Description

BACKGROUND OF THE INVENTION
• 1. Field of the Invention[0001]
• The present inventions are directed to surgical equipment, and in particular, equipment used for irrigating wounds on the human body.[0002]
• 2. Description of the Related Art[0003]
• Basins are widely used in the medical field to collect irrigation fluid during an irrigation procedure of a wound on a patient. The wound may consist of a laceration or a cut that breaks a skin surface. Fractures may also require irrigation procedures. Medical personnel irrigate such wounds to flush out any contaminants from the wound prior and/or subsequent to conducting a medical procedure on the wound area.[0004]
• Irrigation procedures are common in the medical field, particularly in the field of orthopedic surgery, due to the fact that wounds are fairly common injuries, many of them requiring treatment at a medical facility, particularly deep cuts. Therefore, medical facilities tend to maintain a significant number irrigation kits ready for use during surgical procedures. This is also true for emergency room facilities, where patients with wounds requiring immediate treatment generally arrive, and where the number of patients that will arrive throughout a day is impossible to predict. However, the use of irrigation kits is not limited to emergency room procedures and includes other medical procedures as well.[0005]
• Existing irrigation kits typically include at least one basin to collect the irrigation fluid wrapped in plastic or other material preventing dirt or other contamination from coming in contact with the basin. Wrapping the kit in plastic also allows the kits to be kept separate from each other, even if the kits are stacked one on top of another. Moreover, each kit generally includes various components necessary for an irrigation procedure so that medical personnel usually need not open more than one irrigation kit to perform an irrigation procedure. The components, such as the basins, are usually sterilized.[0006]
• When a wound requires irrigation, medical personnel open an irrigation kit to take the basin out of the kit, and place the basin in an area below the region of the patient's body where the wound is located. Then, with an irrigation device, the medical personnel directs an irrigation fluid, such as, but without limitation, water, saline, or a solution including antibacterials and/or antibiotics at the wound area to remove contaminants, tissue and/or bone fragments from the wound.[0007]
• The irrigation device preferably delivers irrigation fluid at a pressure and flow rate sufficient to effectively clean the wound area. The irrigation device may have a shield connected to the device to reduce the amount of irrigation fluid that splashes off the wound field and/or in the direction of the treating medical personnel or on the floor. The shield can further be used to focus the direction of the irrigation fluid on the wound when the device is placed close to the wound area.[0008]
• Throughout the irrigation procedure, medical personnel adjust the location of the basin to collect the irrigation fluid after it strikes the wound area. For example, one may place the basin just below the body part where the wound is located. Alternatively, one may place the basin in a location to which the irrigation fluid flows after striking the wound area.[0009]
SUMMARY OF THE INVENTION
• One aspect of at least one invention disclosed herein includes the realization that a significant amount of labor is unnecessarily wasted during medical irrigation procedures. For example, in a typical irrigation procedure, an open wound or fracture is irrigated with an irrigation device that discharges a stream of irrigation fluid. Typically, a doctor or surgeon manually aims the stream of irrigation fluid into the wound in order to dislodge and flush out contaminants, tissue and/or bone fragments. Occasionally, irrigation fluid will splash out of the wound when the stream of irrigation fluid strikes tissue or bone.[0010]
• The amount of irrigation fluid used for such procedures varies. For example, more irrigation fluid is used for irrigating larger wounds than that used for irrigating smaller wounds. However, the amount of irrigation fluid used may also vary depending on the depth of the wound, e.g., more irrigation fluid being used for deeper wounds. Additionally, the amount of irrigation fluid used may also vary depending on the type and risk of potential contamination. For example, where a wound was partially created during an accident such as impalement, more irrigation fluid may be used compared to that used to irrigate a wound created by a surgeon during a planned procedure or other surgical procedures. Finally, a surgeon may decide to irrigate one wound more than another for various other reasons, such as, but without limitation, the amount of time the wound was open. Thus, it can be difficult to predict the amount of irrigation fluid that will be used to irrigate a wound.[0011]
• During irrigation procedures performed for orthopedic surgery or other major medical procedures, a large amdunt of irrigation fluid is often used, e.g. one to ten liters. Thus, the basin used for collecting the irrigation fluid must be emptied repeatedly, requiring the irrigation procedure to stop, unless additional personnel and/or basins are used. As a full basin is removed, and an empty basin is re-positioned, some irrigation fluid inevitably is spilled on the floor, thus requiring additional towels and cleaning equipment to be used to keep the floor clean. If the towels or equipment is to be re-used, they must be sterilized.[0012]
• An additional consideration with conventional basins is the potential for contamination of medical personnel with the bodily fluids of the patient that are collected in the basin during an irrigation procedure. If the irrigation fluid in the basin is spilled, the irrigation fluid, soft tissue, bone, and other debris contained therein may come in contact with medical personnel, exposing the personnel to contaminated and potentially infectious matter. Such an exposure can result in the transmission of diseases.[0013]
• Thus, one aspect of at least one of the inventions disclosed herein includes the realization that a basin that can be used alone or quickly modified to be actively drained can decrease the risk of transmission of disease and save a significant amount of labor normally associated with surgical irrigation procedures. Such a basin can reduce the number of medical personnel needed for an irrigation procedure and the total man-hours required for the procedure.[0014]
• Thus, in accordance with one embodiment of at least one invention disclosed herein, a basin comprises a sidewall portion and a bottom portion, at least one of the sidewall and bottom portions including at least one convertible portion configured to provide a substantially leak-proof barrier in a first state and to form a drain in a second state through which the basin can be drained, such as, for example, but without limitation, a suction hose commonly used in operating rooms.[0015]
• By including at least one convertible portion in the basin, the basin achieves the dual goals of providing a conventional multi-purpose basin, and providing a basin that can be modified for use during a large volume irrigation procedure. For example, the basin can have any conventional shape, including for example, but without limitation, round, square, rectangular, oval, C-shaped, L-shaped, and kidney. Thus, the basin can be used for irrigation procedures just as any conventional basin is used, as well as non-irrigation related uses such as the temporary placement of instruments or devices. Additionally, the convertible portion can be modified to drain the basin. As such, the basin provides a more convenient device for collecting and discarding irrigation fluid used during an irrigation procedure.[0016]
• For example, in one embodiment the convertible portion includes a frangible portion, which can be broken to form an aperture. A suction hose commonly used in an operating room can be connected to the aperture formed by the broken frangible portion. Thus, personnel handling the basin will not have to stop the irrigation procedure to empty the basin, and are less likely to spill any irrigation fluid, either on the floor or on themselves, during the procedure.[0017]
• In accordance with another embodiment of at least one of the inventions disclosed herein, a wound irrigation kit comprises a grommet that can be readily fitted onto a basin in the kit to allow for draining of the basin during the irrigation procedure. Accordingly, the kit is advantageously versatile, allowing the basin to be used without the grommet for a shortened irrigation procedure, as well as allowing the basin to be readily modified to incorporate the draining attachment for a prolonged irrigation procedure. The grommet is defined by an axis and comprises a fitting part, a sealing part and a channel disposed in the center of the fitting and the sealing part along the axis. The fitting part is configured to be inserted through the convertible portion of the basin so that the sealing part of the grommet forms a substantially watertight seal with the wall of the basin facing the cavity of the basin. The fitting part protrudes out of the body of the basin in a direction away from the basin body. The fitting part also comprises an outer surface configured to securely receive a draining hose for active draining of the basin.[0018]
• In accordance with another embodiment of at least one of the inventions disclosed herein, a wound irrigation kit comprises a cannula optionally having an adhesive surface. The cannula can optionally be made of flexible rubber. In another option, the cannula can be made of a hard plastic. Additionally, the cannula can optionally be configured to have a specific shape, such as, but without limitation, a C-shape, a Z-shape and an L-shape. The adhesive surface can optionally comprise flange integrally formed with the cannula. In another option, the adhesive surface can comprise the outer surface of the cannula itself.[0019]
• In another embodiment of at least one of the inventions disclosed herein, a basin is configured for irrigation of a wound generally located on a knee area of a human leg. For example, the wound may be located on the leg over a kneecap. Additionally, the wound may be located on an upper shin or a lower quadriceps region of the leg, proximally located to the knee area. Use of the basin is not limited to wounds located on a front side of the leg, where the front side is defined as the side on which the knee-cap is located. The basin can also be used in irrigation procedures on a side of the knee or a region behind the knee. Additionally, the basin can be used in irrigation procedures on a wound on an upper calf or a lower hamstring region of the leg, proximally located to the knee area of the leg. Further, the basin can also be used for irrigation procedures on open fractures of other lower extremities.[0020]
• The basin advantageously includes two recesses located on opposite sides of the basin along an upper periphery of the basin. The recesses are configured to receive the leg at two regions proximal to the location of the wound or fracture, so that the wound or fracture is located over the cavity of the basin. Specifically, the recesses are sized so that one is broader than the other, the broader recess configured to comfortably accommodate a larger region of the leg and the other recess configured to comfortably accommodate a smaller region of the leg.[0021]
• For example, the recesses are configured to receive a shin and a thigh portion of the leg. If the wound is located on the kneecap, the recesses disposed on the upper periphery of the basin are capable of receiving the lower quadriceps region and the upper calf region of the leg. Moreover, one of the recesses is sized broader than the other recess, wherein the broader recess is sized to receive the thigh portion and the other recess is sized to receive the shin portion of the leg. Further, the recesses are preferably contoured in shape to comfortably receive the shin and thigh portions. The recesses advantageously allow the basin to more effectively collect the irrigation fluid used to irrigate a wound on the knee region during an irrigation procedure.[0022]
• In still another embodiment of at least one of the inventions disclosed herein, a basin is configured for irrigation of a wound generally located on a human elbow region. For example, the wound may be located on either side of the elbow. Additionally, the wound may be located on a biceps region, a triceps region or a forearm region proximal to the elbow.[0023]
• The basin for use in irrigation of a wound on the elbow region also has two recesses on the upper periphery for receiving two regions of the arm. The recesses are further configured to more effectively collect the irrigation fluid used to irrigate a wound on the elbow region during an irrigation procedure.[0024]
• In another embodiment of at least one of the inventions disclosed herein, a basin is configured for irrigation of a wound generally located on a human ankle region. For example, the wound may be located on either side of the ankle. Additionally, the wound may be located on a lower shin or a lower calf region o the leg proximal to the ankle.[0025]
• The basin for use in irrigation of a wound on the ankle region (i.e., ankle-basin) is configured similarly to the basin used to irrigate a wound on the elbow region (i.e., elbow-basin). The ankle-basin preferably has a taller sidewall and differently sized recesses than the elbow-basin. Specifically, the ankle-basin has two recesses on the upper periphery for receiving two regions of the leg proximal to the ankle. The recesses are configured to more effectively collect the irrigation fluid used to irrigate a wound on the ankle region.[0026]
• In another embodiment of at least one of the inventions discloses herein, a basin comprises three recesses on the upper periphery. The first and third recesses are optionally sized to receive a human leg, while the second recess is sized to receive a human upper arm. Therefore, according to this embodiment, the basin can be used to irrigate wounds on the knee and elbow regions. Similarly, the second recess can optionally be sized to receive a human foot. Therefore, according to this embodiment, the basin can be used to irrigate wounds on the knee and ankle regions.[0027]
• In still another embodiment of at least one of the inventions disclosed herein, a basin can have four recesses. The recesses can optionally have the same dimensions. In another option, only three of the four recesses can have the same dimensions. In still another option, only two of the recesses can have the same dimensions. In yet another option, the recesses can each have different dimensions. Accordingly, the basin can be configured to receive various parts of human extremities.[0028]
• In another embodiment of at least one of the inventions disclosed herein, a basin comprises one recess on the upper periphery of the basin. The recess is preferably configured to receive a human extremity. For example, the recess can be configured to receive a human forearm to irrigate wounds located below the elbow. In another example, the recess can be configured to receive a human thigh region to irrigate wounds located below the knee. The height of the basin sidewalls is greater if the basin is used to irrigate leg wounds than if it is used to irrigate arm wounds.[0029]
• In another embodiment of at least one of the inventions disclosed herein, a basin is configured for irrigation of a wound on a human shoulder. The wound can be located on an upper arm region near the juncture of the arm with the shoulder. The wound can also be located on a shoulder blade region or a pectoral region near the juncture with the arm.[0030]
• The basin is preferably generally C-shaped, which advantageously allows the basin to be fitted around the upper arm region proximal to the wound. However, the basin can optionally have other shapes, such as, but without limitation, oval, round, square, kidney and horseshoe. The basin is further configured to have a contact region on an outer surface of the basin, wherein the contact region is advantageously configured to fit against a portion of a circumference of the upper arm. Accordingly, the basin is configured to more effectively collect the irrigation fluid used to irrigate a wound on the shoulder region during an irrigation procedure.[0031]
• In yet another embodiment of at least one of the inventions disclosed herein, a basin is configured for irrigation of a wound on a human hip. The wound may be located on a buttock region or a lower hip region near the juncture with the buttock.[0032]
• The basin advantageously has a contact region formed on the upper periphery of the basin. Moreover, the contact region advantageously makes substantial contact with the human anatomy from just above a hip to just below a buttock. Further, the contact region is advantageously recessed downward relative to the upper periphery of the basin, allowing the upper periphery to operate as a splash shield during the irrigation procedure.[0033]
• Another embodiment of at least one of the inventions disclosed herein includes providing a flexible irrigation shield that can be attached to an irrigation device, such as the irrigation device shown in U.S. Pat. No. 6,156,004. The shield can also be readily modified to vary its length. Such a shield advantageously allows medical personnel to vary the splash-prevention area as needed for a specific irrigation procedure. The irrigation shield can have a variety of shapes. For example, the shield can be in the shape of a circle or a square. The shield can also be made of a variety of materials. For example, the shield can be made of a clear plastic.[0034]
• Still another embodiment of at least one invention disclosed herein is directed to an irrigation kit that provides a plurality of the components useful for an irrigation procedure. The kit includes a plurality of basins, each basin configured to receive a body part that is to be irrigated to more effectively collect an irrigation fluid in the basin. Each basin comprises a body with a base and at least one wall defining a cavity configured to collect irrigation fluid. Additionally, each basin is advantageously configured to be readily modified for active draining of the basin. Each basin optionally has at least one convertible portion on the body, which may optionally be a frangible portion in the form of a circle. The convertible portion is preferably located near the bottom of the basin wall, wherein the convertible portion may be modified to form a drain. Further, the base of each basin is preferably slanted at an angle toward an end of the basin proximal to the convertible portion so that irrigation fluid collected in the basin advantageously rolls toward the drain formed on the basin body when the convertible portion is modified.[0035]
• Another aspect of at least one of the inventions disclosed herein includes the realization that during certain types of surgery, such as for example, but without limitation, orthopedic surgery, the standard suction tubing commonly used suffers from a clogging problem that can be caused by constrictions that form in the tubing during packaging and storage. For example, typical operating rooms and other medical facilities use suction tubing having an inner diameter (I.D.) of about 5-6 mm in a relaxed state. Additionally, all of the components which are configured to be connectable with the 5-6 mm I.D. tubing, are sized and shaped so that they will only allow debris to pass into the suction tubing that is smaller than 5-6 mm.[0036]
• During certain medical procedures, only liquids such as bodily fluids, humors, or irrigation fluid, is removed with a suction device. The typical 5-6 mm tubing does not suffer from a clogging problem when only liquids are being suctioned. However, during certain types of surgery, such as orthopedic surgery, for example, a significant amount of bodily tissues can be drawn into a suction device. It has been found that the conventional 5-6 mm I.D. tubing commonly used in operating rooms suffers from a bottle-necking problem, due in part to the packaging technique used in marketing the tubing. More specifically, the conventional 5-6 mm tubing commonly stocked for operating room use is folded into a sterilized package. The tubing is soft and flexible. Typically, the tubing is between 5 and 20 feet long. Thus, when the tubing is folded, the tubing collapses in the area of each fold. After the tubing has been stored for a significant amount of time, the collapsed portions of the tubing, usually in the area of the folds, remain in a partially collapsed state.[0037]
• During an orthopedic operation, such as a joint replacement, many bone chips and clumps of tissue must be removed from the wound prior to closing. Thus, an orthopedic surgeon typically uses a small suction device having a suction tip with restricted openings, to suck out irrigation fluid, clumps of tissue, and bone chips. The restricted openings are sized so as to prevent large clumps of tissue and bone fragments from entering the suction hose. However, despite the size of the restricted opening, tissue clumps and bone fragments pass through the restricted opening which are large enough to form clogs at bottlenecks in the suction circuit. When a clog forms in the suction tubing, it is often difficult to dislodge the debris causing the clog. Thus, it is often necessary to stop the procedure, shut off the vacuum device, replace the tubing, then continue the procedure. This interruption can increase the labor hours required for certain procedures, and thus represents additional costs suffered by the medical facility in performing the medical procedure.[0038]
• It has been found that the partially collapsed portions of conventional suction tubing contributes significantly to the clogging problem. Another aspect of at least one of the inventions disclosed herein includes the realization that where a larger diameter suction tubing is partially collapsed, the resulting cross sectional size of the collapsed portion can be large enough to reduce the likelihood of clogs from forming at the partially collapsed portion.[0039]
• Thus, in accordance with yet another aspect of at least one of the inventions disclosed herein, a suction hose kit comprises a sterilized package enclosing tubing having an inner diameter of at least about 8 mm. As such, the tubing can be made from the typically-used soft plastic material and folded into a compact shape, without causing constrictions that cause the clogging problem associated with the conventional smaller diameter suction tubing. Other objects, advantages, and features of the present invention will become readily apparent to those skilled in this art from the ensuing detailed description of preferred embodiments thereof.[0040]

• The[0089]outer surface12bcomprises twoend surfaces18a,18barranged at longitudinal ends17a,17bof amajor axis17, respectively, and disposed generally perpendicular to themajor axis17. Theouter surface12balso comprises twoside surfaces18c,18dextending between the longitudinal ends17a,17band generally parallel to themajor axis17. As used herein, the term “major axis” generally refers to an axis that passes through thebasin10 along the longitudinal direction of thebasin10, i.e., along the greatest dimension or “length” of thebasin10.
• The[0090]basin10 further comprises afirst recess15 configured to receive, for example, a human thigh and asecond recess16 configured to receive, for example, a human shin. Thefirst recess15 is preferably broader than thesecond recess16. Thefirst recess15 is disposed along theupper periphery14 at thelongitudinal end17aof thebasin10.

• As shown in FIG. 2, the[0094]base11 of thebasin10 is generally horizontal relative to the resting surface and rectangular in shape. Moreover, thebase11 is substantially at zero degrees relative to the resting surface. However, thebase11 of thebasin10 is not limited to the rectangular shape or to being parallel to the resting surface. For example, thebase11 may be inclined at an angle greater than zero degrees and configured to direct irrigation fluid on the base11 in the direction of theconvertible portion19. For example, thewall12 can include downwardly protruding portions (not shown) which raise theend17arelative to theend17b. Alternatively, thebase11 can be mounted to thewall12 such that the end of the base11adjacent end17ais higher than the end of the base11 adjacent theend17b. In another example, thebase11 can be configured to be adjustably inclined to a plurality of angles such that the end of the base11adjacent end17ais higher than the end of the base11 adjacent theend17b. For example, but without limitation, the outer surface of the base11 can be configured to releasably engage at least one shim (not shown) to selectively change the inclination of the base11 relative to the resting surface. Thus, thekit1 can include abasin10 and at least one shim to selectively vary the inclination of thebase11.
• The[0095]peripheral wall12 defines a thickness, which preferably is uniform along the periphery of thewall12. The thickness is configured to provide thewall12 with adequate structural rigidity to prevent excessive flexing of thewall12. Accordingly, the thickness can optionally have various sizes, each of which is capable of providing thewall12 with adequate structural rigidity. For example, the thickness can be between 1 mm and 5 cm.
• The[0096]wall12 defines amaximum height12dalong the periphery of thewall12. Themaximum height12dis defined as the distance from the resting surface to theupper periphery14 of thewall12. Thewall12 also defines a minimum height12eat thelongitudinal end17aof the basin. The minimum height12eis defined as the distance from the resting surface to aminimum point15aof thefirst recess15. Further, the wall defines aminimum height12fat thelongitudinal end17bof thebasin10. Theminimum height12fis defined as the distance from the resting surface to aminimum point16aof thesecond recess16. Theheights12d,12e,12fare configured to be sufficiently large to allow thecavity13 defined by thewall12 and the base11 to hold a substantial volume of fluid.
• The[0097]upper periphery14 in the illustrated embodiment is generally parallel to theaxis17. However, theupper periphery14 can optionally be inclined inwardly so as to drain liquid falling on theperiphery14 back into thecavity13. Additionally, theperiphery14 can have a curved surface so that theperiphery14 does not have theedges14a,14band to provide a seamless junction between theupper periphery14 and theouter surface12b.
• The[0098]first recess15, as illustrated in FIG. 2, extends from theedges14cof theupper periphery14 to theminimum point15a. Moreover, therecess15 has a curved shape. However, thefirst recess15 can Optionally have any contoured shape configured to receive, for example, a human thigh. Accordingly, therecess15 is not limited to the arcuate shape illustrated in FIG. 2. Therecess15 further comprises a recess surface15band edges15c,15d. Therecess15 preferably joins to thewall12 at theedge15d. Optionally, therecess15 can join to thewall12 at theedge15c. The recess surface15bextends horizontally from theedge15cto theedge15dadjacent theend surface18a. The recess surface15bcan optionally be curved between theinner surface12aand theend surface18ato provide a seamless junction between the surface15band thesurfaces12a,18awithout theedges15c,15d. The recess surface15bcan also optionally be inclined inwardly so as to drain liquid falling on the surface15bback into thecavity13. Thefirst recess15 may also have a contoured juncture with theupper periphery14 to provide a seamless junction between the recess surface15band theupper periphery14, without theedges14c.
• Similarly, the[0099]second recess16 has a generally curved shape, as illustrated in FIG. 2, and extends from theedges14cof theupper periphery14 to theminimum point16a. Moreover, thesecond recess16 has a curved shape, which can be different than the curved shape of thefirst recess15. Accordingly, thefirst recess15 and thesecond recess16 can optionally be asymmetric. Additionally, thesecond recess16 can optionally have any contoured shape configured to receive, for example, a human shin. Therefore, therecess16 is not limited to the arcuate shape illustrated in FIG. 2. Therecess16 further comprises arecess surface16band edges16c,16d. Therecess16 preferably joins to thewall12 at the edge16d. Optionally, therecess16 can join to thewall12 at theedge16c. Therecess surface16bextends horizontally from theedge16cto the edge16dadjacent theend surface18b. Therecess surface16bcan optionally be curved between theinner surface12aand theend surface18bto provide a seamless junction between thesurface16band thesurfaces12a,18bwithout theedges16c,16d. Therecess surface16bcan also optionally be inclined inwardly so as to drain liquid falling on thesurface16bback into thecavity13. Thesecond recess16 may also have a contoured juncture with theupper periphery14 to provide a seamless junction between therecess surface16band theupper periphery14, without theedges14c.
• The[0100]convertible portion19 can comprise a variety of structures and combination of structures. Moreover, as noted above, one or a plurality ofconvertible portions19 can be disposed along the periphery of thebasin10 or on thebase11.
• For example, but without limitation, the[0101]convertible portion19 can comprise ahole19 formed on the base11 or thewall12 covered with a peel-off seal19a, as illustrated in FIG. 2b. The peel-off seal19acan be disposed on theinner surface12aor theouter surface12bof thebasin10, or on the bottom of thebase11. Preferably, theseal19ais constructed of an adhesive applied to a thin light-weight plastic, such as, for example, but without limitation, a thermo-plastic. The adhesive is configured to allow the thin plastic portion to be peeled-off of thebasin10 by hand.
• The[0102]basin10 can optionally comprise a strainer portion (not shown) over thehole19, where the strainer is configured to capture bone chips, soft tissue, and other debris. The peel-off seal19aadvantageously provides a simple way of creating a drain on thebasin10 or any container used for collecting contaminated and potentially infectious fluids, such as, but without limitation, bed pans.
• A[0103]kit1 including thebasin10 can also comprise additional peel-offseals19aconfigured to cover thehole19. The additional peel-offseals19acan be used to cover thehole19 if a drain is no longer desired.
• In another example, the[0104]convertible portion19 can comprise a threadedhole19 formed on thewall12 and a threadedplug19ato plug thehole19, as illustrated in FIG. 2c. Theplug19aand threadedhole19 advantageously allow medical personnel to readily modify theconvertible portion19 to create a drain in thebasin10 by removing theplug19afrom thehole19. Similarly, personnel can insert theplug19ainto thehole19 if a drain is no longer desired. The threadedhole19 and threadedplug19aadvantageously provide a simple way of creating a drain on thebasin10 or any container used for collecting contaminated and potentially infectious fluids, such as, but without limitation, bed pans.
• In still another example, the[0105]convertible portion19 can comprise ahole19 formed on thewall12 and aremovable cork19ato cover thehole19, as illustrated in FIG. 2d. Thecork19aadvantageously allows medical personnel to readily modify theconvertible portion19 to create a drain in thebasin10 by removing thecork19afrom thehole19. Similarly, personnel can insert thecork19ainto thehole19 if a drain is no longer desired. Thehole19 andremovable cork19aadvantageously provide a simple way of creating a drain on thebasin10 or any container used for collecting contaminated and potentially infectious fluids, such as, but without limitation, bed pans.
• In yet another example, the[0106]convertible portion19 can comprise anipple19 extending outward from theside surface18dhaving aremovable cap19a, as illustrated in FIG. 2e. Thenipple19 can be molded onto theside surface18d. Optionally, thenipple19 can be removably screwed onto a threaded hole on theside surface18d. Thenipple19 defines achannel19bextending therethrough to theinner surface12aof thebasin10. Thenipple19 and cap19aadvantageously provides a way to create a drain in thebasin10 by removing thecap19afrom thenipple19, which allows fluid in thebasin10 to flow through thechannel19bof thenipple19. Similarly, medical personnel can place thecap19aover thenipple19 if a drain is no longer desired. Thenipple19 andremovable cap19aadvantageously provide a simple way of creating a drain on thebasin10 or any container used for collecting contaminated and potentially infectious fluids, such as, but without limitation, bed pans.
• In another example, the[0107]convertible portion19 can comprise anipple19 having a strainer (not shown) and aremovable cover19a, such as, but not limited to, a peel-off seal19a, as illustrated in FIG. 2f. As discussed above, thenipple19 defines achannel19bextending therethrough to theinner surface12a. The peel-off seal19ais preferably disposed over the protrudingnipple19. Alternatively, the peel-off seal19acan be disposed on theinner surface12aover the strainer. This configuration advantageously provides aconvertible portion19 that is readily modifiable to create a drain in thebasin10 by peeling off the peel-off seal19a, and that captures soft tissue, bone chips, and other debris during the draining of thebasin10. Thebasin10 can also comprise additional peel-offseals19aconfigured to cover thenipple19′ Thenipple19 and peel-off seal19aadvantageously provide a simple way of creating a drain on thebasin10 or any container used for collecting contaminated and potentially infectious fluids, such as, but without limitation, bed pans.
• In still another example, the[0108]convertible portion19 can comprise acannula19 extending generally vertical to the resting surface from anaperture19aproximal to the base11 to anaperture19bproximal to and disposed on a plane generally parallel to theperiphery14, as illustrated in FIG. 2g. However, thecannula19 can optionally extend above theperiphery14, as shown in phantom in FIG. 2g.
• The[0109]cannula19 can optionally be integrally molded to theinner surface12aof thebasin10. In another option, thecannula19 can optionally be integrally molded to theouter surface12bof thebasin10 and extend through thewall12 such that theaperture19ais disposed generally along thebase11. In still another option, theaperture19bof thecannula19 can face away from thebasin10. In yet another option, thecannula19 can be removably attached to theinner surface12aof thebasin10.
• The[0110]aperture19aproximal to the base11 optionally comprises aperforated screen19cto prevent bone chips, soft tissue, and other debris from entering the cannula. A peel-off seal (not shown) can optionally be disposed over theperforated screen19c. Theaperture19bproximal to theperiphery14 is configured to receive a fitting to actively drain thebasin10. Optionally, theaperture19bproximal to the periphery can receive and hold a flexible tube to actively drain thebasin10. As another option, the portion of thecannula19 proximal to theperiphery14 includes a nipple (not shown) sized to fit within a suction hose commonly used in operating rooms.
• In yet another example, the[0111]convertible portion19 can comprise aclamp19, as illustrated in FIG. 2h. Theclamp19 can optionally be integrally molded to theinner surface12aof thebasin10. In another option, theclamp19 can be removably attached to theinner surface12aof thebasin10. Theclamp19 comprises acontact surface19adefined by twoarms19babout an axis. Thecontact surface19ais configured to receive a tube, but allow said tube to be adjusted along said axis in response to a force. Thearms19bare configured to hold the tube against thecontact surface19a. Theclamp19 advantageously provides a simple structure on thebasin10 that can be used in conjunction with a tube or a fitting to actively drain thebasin10. Moreover, the tube can advantageously be adjusted while thearms19bof theclamp19 hold it. Medical personnel can thus adjust the tube to a position that provides the best active draining of thebasin10.
• In another example, the[0112]convertible portion19 can comprise aremovable holder19dhaving at least oneclip19e, as shown in FIG. 2i. Twoclips19eare shown in the illustrated embodiment. Theclips19eare configured to engage and hold a conventional suction hose against theholder19dand proximal to thebase11 of thebasin10 for active draining of thebasin10. Theclips19eare optionally manually actuated to engage the suction hose. Similarly, theclips19eare optionally manually actuated to release the hose when active draining is no longer desired. Theholder19dis configured to fit over theperiphery14 of thebasin10 such that it hangs generally vertical to the resting surface. Thus, akit1 including anirrigation basin10 can include aremovable holder19dhaving at least oneclip19eto allow thebasin10 to be readily converted for draining.
• In still another example, the[0113]convertible portion19 can comprise anaperture19gformed on theupper periphery14 of thebasin10, as illustrated in FIG. 2j. The aperture.19gis configured to align with afirst cannula19hdisposed under theperiphery14 such that an upper end of thefirst cannula19habuts against an underside of theperiphery14 about theaperture19g. Thefirst cannula19hpreferably has an outer diameter that is greater than the diameter of theaperture19g. The upper end of thefirst cannula19his configured to receive a lower end of asecond cannula19ithat is inserted through theaperture19gand through the upper end of thefirst cannula19h. Thesecond cannula19ipreferably has an outer diameter that is smaller than an inner diameter of thefirst cannula19h. Thecannulas19h,19iare preferably made of a hard plastic. Optionally, thecannulas19h,19ican be made of a flexible rubber.
• With reference to[0114]2kin yet another modification, theconvertible portion19 can comprise arecess19jdefined on theinner surface12aof thewall12. Therecess19jpreferably is configured to releasably engage a suction hose that is commonly used in an operating room or medical facility. For example, the Sherwood Medical Company of St. Louis, Mo. manufacturers suction hose under the trade name “argyle® non-conductive connecting tube with shore group female molded connectors”. The argyle® suction hose has an inner diameter of about 6 millimeters and an outer diameter of about 9 millimeters. Thus, therecess19jpreferably is configured to releasably engage a hose having an outer diameter of about 9 millimeters with an interference fit.
• For example, the[0115]recess19jcan includelateral edges19k,191. Arear wall19mcan connect the lateral edges19k,191. Preferably, the spacing W between thelateral edges19k,191 is less than about 9 millimeters. Optionally, the lateral edges19k,191 can include tabs (not shown) extending from the lateral edges19k,191, thereby further reducing the minimum clearance between thelateral edges19k,191. Thus, the standard argyle® suction hose can be snapped into therecess19j. Further, the lateral edges19k,191 andrear wall19mare sized so as to provide an interference fit with the outer surface of suction hose, such as the argyle® 6 millimeter suction hose, or any other suction hose. Thus, once the suction hose is snapped into therecess19j, the hose is held in place through an interference fit therewith. As such, thebasin10 illustrated in FIG. 2kcan be quickly and conveniently modified by attaching a commonly used suction hose to theconvertible portion19.
• Optionally, a strainer (not shown) can be attached to the lower end of the suction hose to be connected to the[0116]convertible portion19. Thus, the strainer can prevent large clumps of tissue and bone fragments from entering the suction hose, so as to reduce the likelihood of clogging.
• According to the illustrated embodiment of the[0117]basin10, the at least oneconvertible portion19 is in the form of an annularly extendingscore19 defining a frangible portion disposed on theside surface18d. However, thescore19 can be disposed on any portion of thewall12 or thebase11. Additionally, a plurality ofscores19 can optionally be disposed on thebasin10. Thescore19 is configured to form an aperture through thewall12 orbase11 to drain thecavity13 following the removal of the material bounded by thescore19 from thewall12. Thescore19 is preferably disposed near the bottom of thesurface18d, close to the resting surface. However, thescore19 can be disposed in any location capable of providing an effective drain for thecavity13 upon the removal of the material bounded by thescore19 from thewall12. Additionally, though thescore19 preferably comprises a circular shape, as shown in the illustrated embodiment, thescore19 can comprise any shape that provides an effective drain for thecavity13. For example, thescore19 can comprise a slit.
• In preparation for the irrigation of a knee wound, medical personnel remove the cover[0118]2 from thekit1 and remove thebasin10 from the kit. If the wound is in the knee area along the front part of the leg, personnel have the patient sit on an examination table with their leg extended. The patient can optionally lie on his or her back if the wound is on the back of the knee. Medical personnel then place thebasin10 under the extended leg of the patient so that the patient's thigh rests on thefirst recess15 and the patient's shin rests on thesecond recess16. Accordingly, the patient's wound is disposed over thecavity13 of thebasin10. If the wound is in the knee area along the back part of the leg, personnel have the patient lay on their stomach with their injured leg extended. The personnel then place thebasin10 under the patient's leg as described above. If the personnel wish to actively drain thebasin10 during the irrigation procedure, the personnel modify theconvertible portion19. As noted above, thebasin10 can comprise a plurality ofconvertible portions19 disposed along the periphery of thebasin10, allowing personnel to choose theconvertible portion19 that best accommodates the draining of thebasin10 or create additional drains. The draining device and active draining process are further described below.
• If the[0119]convertible portion19 comprises ahole19 formed on thewall12 covered with a removable cover, such as a peel-off seal, a threaded plug, and a cork, one can modify theconvertible portion19 by removing the cover from thehole19. This allows irrigation fluid in thecavity13 of thebasin10 to flow out of the basin through thehole19.
• In another example, if the[0120]convertible portion19 comprises anipple19 having aremovable cap19a, personnel can modify theconvertible portion19 by removing thecap19afrom thenipple19. In still another example, if theconvertible portion19 comprises anipple19 having a strainer and a peel-off seal19a, personnel can modify theconvertible portion19 by peeling off theseal19a. Personnel can then connect a suction hose to the nipple and connect the suction hose to a suction device to actively drain thebasin10.
• In yet another example, if the[0121]convertible portion19 comprises acannula19, personnel can insert a conventional tube into thecannula19. Personnel can then connect an end of the suction tube to a suction device to actively drain thebasin10.
• In another example, if the[0122]convertible portion19 comprises aclamp19, medical personnel can attach a conventional suction hose to theclamp19 so that an end of the suction hose is proximal to thebase11. Personnel can then connect a second end of the hose to a suction device to actively drain thebasin10.
• In still another example, if the[0123]convertible portion19 comprises aremovable holder19dwith at least oneclip19e, medical personnel can attach the at least oneclip19eto a conventional suction hose so that an end of the suction hose is proximal to thebase11. Personnel can then connect a second end of the hose to a suction device to actively drain thebasin10.
• In another example, if the[0124]convertible portion19 comprises anaperture19gformed on theupper periphery14, personnel can place afirst cannula19hunder theupper periphery14 so that it aligns with theaperture19g. Personnel can then insert asecond cannula19ithrough theaperture19gand thefirst cannula19h. Personnel can then connect a second end of thesecond cannula19ito a suction hose or a suction device to actively drain thebasin10.
• In yet another example, personnel can attach the adhesive surface[0125]5aof thecannula5 to theinner surface12aof thebasin10 so that one end of thecannula5 is proximal to thebase11 and the other end of thecannula5 engages a suction device. In another option, thecannula5 is configured to self-support against theinner surface12aof thebasin10 without the adhesive surface5a. The suction device can then be operated to actively drain thebasin10.
• In the illustrated embodiment, where the[0126]convertible portion19 comprises afrangible portion19, personnel can break thefrangible portion19 to create a drain for thebasin10. Personnel can optionally insert a draining device into the drain and attach a suction hose to an end of the draining device. Personnel can then attach a second end of the suction hose to a suction device to actively drain thebasin10.
• Irrigation fluid is then directed to the wound region to remove any contaminants from the wound region. The irrigation fluid directed to the wound region subsequently collects in the[0127]cavity13 of thebasin10. Therecesses15,16 that receive the thigh and shin of the patient, respectively, further improve the fluid-collection ability of thecavity13 by reducing escape of irrigation fluid through the juncture of the thigh and shin with therecesses15,16, respectively.
• With reference to FIG. 3, the draining device is illustrated therein. In the illustrated embodiment, the draining device is a[0128]grommet20. Thegrommet20 can optionally comprise a peel-off seal (not shown). Thegrommet20 can also optionally comprise a strainer, (not shown). In the illustrated embodiment, thegrommet20 defines anaxis21 along the longitude of thegrommet20, theaxis21 having twolongitudinal ends21a,21b. Thegrommet20 comprises a sealingpart22 and afitting part24. Thegrommet20 is preferably made of a rigid material. For example, thegrommet20 can be made of a hard plastic. Optionally, the sealingpart22 and thefitting part24 can be made of different materials. For example, the sealingpart22 can be made of a flexible rubber and thefitting part24 can be made of a hard plastic.
• The sealing[0129]part22 is disposed at thelongitudinal end21band comprises a sealingsurface23afacing in the direction of thelongitudinal end21a. The sealingsurface23ais configured to provide a substantially watertight seal with a mating surface (not shown) in contact with the sealingsurface23a. The sealingpart22 also comprises adrain surface23bfacing in the direction away from thelongitudinal end21a. Thedrain surface23bdefines adrain aperture23cpreferably disposed in a substantially central position on thedrain surface23b. Both surfaces23a,23bextend about theaxis21. The sealing part also comprises abottom surface23dproximal to thedrain aperture23c. Thebottom surface23dis preferably a flat surface.
• As illustrated in FIG. 3[0130]a, thegrommet20 optionally comprises astrainer23edisposed on thedrain surface23bover thedrain aperture23c. Thestrainer23eis configured to advantageously capture any bone debris, soft tissue, and other debris.
• The[0131]fitting part24 comprises astem25 having anouter surface25aextending circumferentially about theaxis21. Thefitting part24 further comprises a plurality ofsteps26 along theouter surface25aof thestem25, proximal to thelongitudinal end21a. In the illustrated embodiment, thefitting part24 of thegrommet20 has threesteps26.
• The plurality of[0132]steps26 is configured to engage a tube disposed over thestem25 at thelongitudinal end21a. For example, thesteps26 can be sized to elastically deform and thereby engage and seal against the inner surface of a suction hose commonly used in an operating room. Thesteps26 comprise a runningsurface26aand a steppingsurface26b, where bothsurfaces26a,26bextend circumferentially about theaxis21. The runningsurface26ais preferably angled downward, relative to theaxis21, in the direction of thelongitudinal end21a. The runningsurface26aof the plurality ofsteps26 preferably has the same angle relative to theaxis21 for each of thesteps26. Optionally, the runningsurface26ahas a different angle relative to theaxis21 for each of thesteps26, the angle increasing with each of thesteps26 in a direction away from thelongitudinal end21a. The steppingsurface26bis preferably at substantially a ninety degree angle relative to theaxis21 and comprises a same height for each of the plurality ofsteps26. As used here, the height is the vertical distance between the stepping surfaces26bof twoadjacent steps26. Optionally, the steppingsurface26bhas a different height for each of thesteps26, the height increasing with each of thesteps26 in a direction away from thelongitudinal end21a.
• A[0133]channel27, illustrated by the short dashed lines in FIG. 3, is defined inside thegrommet20 about theaxis21 and extends from an endpoint of the stem at thelongitudinal end21athrough the sealingpart22, to thedrain aperture23cat thelongitudinal end21b. As illustrated in FIG. 3b, thechannel27 is optionally flared in the direction of thelongitudinal end21bsuch that the diameter of thechannel27 at thelongitudinal end21band the diameter of thedrain aperture23cis greater than the diameter of thechannel27 at thelongitudinal end21a. This feature advantageously provides a larger drain area.
• With reference to FIG. 4, use of the[0134]grommet20 to provide a basin of thekit1 with a drain for use in an active draining process is illustrated therein. In the illustrated embodiment, thegrommet20 is used to provide thebasin10 with a drain.
• To form the drain on the[0135]basin10, medical personnel first modify theconvertible portion19 to form a drain. In the illustrated embodiment, theconvertible portion19 is afrangible portion19 in the form of an annularly extendingscore19. However, as discussed above, theconvertible portion19 can comprise a variety of different structures and combination of structures. In the illustrated embodiment, personnel preferably remove the material by punching the material through thewall12, creating anaperture28 through thewall12, extending from theside surface18dto theinner surface12a. Medical personnel can use any number of instruments to remove this material. For example, personnel can use their finger, or another instrument with an end surface corresponding to the surface of the material bound by thescore19.
• Upon modification of the[0136]convertible portion19, personnel insert thefitting part24 of thegrommet20 through theaperture28 at theinner surface12aso that the sealingsurface23acontacts theinner surface12ato form a substantially watertight seal. Thebottom surface23doptionally contacts thebase11. Personnel subsequently direct atube40 connected to a suction device (not shown) over thelongitudinal end21aof thestem25, so that the plurality ofsteps26 substantially grip thetube40. Medical personnel can then operate the suction device during the irrigation procedure to draw irrigation fluid from thecavity13 of thebasin10, through thechannel27 and into thetube40.
• With reference to FIG. 5, the[0137]irrigation basin30 for irrigating a wound on a human extremity is illustrated therein. For example, thebasin30 can be used for irrigating a wound on a human elbow. Thebasin30 comprises a base31 having a generally rectangular shape and aperipheral wall32. Thebasin30 can have other shapes, such as, but without limitation, round, oval, kidney, and square. Thewall32 is substantially at ninety degrees relative to the resting surface. Thebase31 and thewall32 define acavity33 in the center of thebasin30. Theperipheral wall32 also defines aninner surface32afacing toward thecavity33 of thebasin30 and anouter surface32bfacing away from thecavity33 of thebasin30. Thebasin30 also comprises anupper periphery34 having aninner edge34aand anouter edge34b. Theouter edge34bpreferably joins theupper periphery34 to theouter surface32b. In the illustrated embodiment, theperiphery34 defines an inwardly extending flange having awidth32c, supported only by the connection between theouter edge34bto thewall32. Alternatively, the thickness of thewall32 can be sufficient to form theperiphery34. In another option, theinner edge34ajoins theupper periphery34 to theouter surface32band theperiphery34 is supported only by the connection between theinner edge34ato thewall32.
• The[0138]basin30 is preferably made of a hard plastic material. For example, but without limitation, thebasin30 can be made of polyurethane or polypropylene, among other materials. The material is preferably biocompatible and hypo-allergenic. Thebasin30 can also be made of metal, such as, but without limitation, stainless steel. Additionally, thebasin30 is preferably sterilized for use in medical procedures. Thebasin30 can optionally be re-useable.
• The[0139]outer surface32bcomprises twoend surfaces38a,38barranged at longitudinal ends37a,37bof amajor axis37, respectively, and generally perpendicularAo themajor axis37. Theouter surface32balso comprises twoside surfaces38c,38dextending between the longitudinal ends37a,37band generally parallel to themajor axis37. As used herein, the term “major axis” generally refers to an axis that passes through thebasin30 along the longitudinal direction of thebasin30, i.e., along the greatest dimension or “length” of thebasin30.

In one example, theconvertible portion39 can be centrally disposed on the bottom of thebase31. In the illustrated embodiment, theconvertible portion39 is disposed on theside surface38d.
• In the illustrated embodiment, the[0143]base31 of thebasin30 is generally horizontal relative to the resting surface and rectangular in shape. Moreover, thebase31 is substantially at zero degrees relative to the resting surface. However, thebase31 of thebasin30 is not limited to the rectangular shape or to being parallel to the resting surface. For example, thebase31 may be inclined at an angle greater than zero degrees and configured to direct irrigation fluid on the base31 in the direction of theend surface38bnearest to theconvertible portion39. For example, thewall32 can include downwardly protruding portions (not shown) which raise theend37arelative to theend37b. Alternatively, thebase31 can be mounted to thewall32 such that the end of the base31adjacent end37ais higher than the end of the base31 adjacent theend37b.

• The[0146]upper periphery34 in the illustrated embodiment is generally parallel to theaxis37. However, theupper periphery34 can optionally be inclined inwardly so as to drain liquid falling on theperiphery34 back into thecavity33. Additionally, theperiphery34 can have a curved surface so that theperiphery34 does not have theedges34a,34band to provide a seamless junction between theupper periphery34 and theouter surface32b.
• The[0147]first recess35, as illustrated in FIG. 5, extends from theedges34cof theupper periphery34 to theminimum point35a. Moreover, therecess35 has a curved shape.

Thescore39 is configured to form an aperture through thewall32 orbase11 to drain thecavity33 following the removal of the material bounded by thescore39 from thewall32. Thescore39 is preferably disposed near the bottom of thesurface38d, close to the resting surface. However, thescore39 can be disposed in any location capable of providing an effective drain for thecavity33 upon the removal of the material bounded by thescore39 from thewall32. Additionally, though thescore39 preferably comprises a circular shape, as shown in the illustrated embodiment, thescore39 can comprise any shape that provides an effective drain for thecavity33. For example, thescore39 can comprise a slit.
• In preparation for the irrigation of an elbow wound, medical personnel remove the cover[0154]2 from thekit1 and remove thebasin30 from the kit. If the wound is in the elbow area, medical personnel have the patient place the patient's upper arm on thefirst recess35 and the patient's forearm on thesecond recess36 so that the wound is disposed over thecavity33 of the basin and faces away from the base.31 of thebasin30.
• If medical personnel wish to actively drain the[0155]basin30 during the irrigation procedure, as described above with respect to thebasin10, the personnel modify theconvertible portion39 to create a drain in thebasin30. Thebasin30 is then ready to be actively drained. In the illustrated embodiment, where theconvertible portion39 comprises afrangible portion39, medical personnel can break thefrangible portion39 to create a drain for thebasin30. Personnel can optionally insert a draining device, such as thegrommet20, into the drain and attach a suction hose to the draining device. Personnel can then attach a second end of the suction hose (not shown) to a suction device (not shown) to actively drain thebasin30.

In another option, thecannula5 is configured to self-support against theinner surface32aof thebasin30 without an adhesive surface. Personnel can then attach a second end of thecannula5 to a suction device, as described above.
• Irrigation fluid is then directed to the wound region to remove any contaminants from the wound region. The irrigation fluid directed to the wound region subsequently collects in the[0157]cavity33 of thebasin30. Therecesses35,36 further improve the fluid-collection ability of thecavity33 by reducing escape of irrigation fluid through the juncture of the patient's arm with therecesses35,36.

Medical personnel then place the[0159]basin30 under the extended leg of the patient so that the inner side of the patient's leg along the shin region rests on thefirst recess35 of thebasin30 and the inner side of the patient's foot rests on thesecond recess36 of thebasin30. As used here, the outer side means the side facing away from the patient's body and the inner side means the side facing toward the patient's other leg when the patient stands-up straight. Accordingly, the patient's wound is disposed over thecavity33 of thebasin30. Likewise, if the wound is in the ankle area along the inner side of the leg, personnel have the patient sit on the examination table with their leg extended. Personnel then place thebasin30 under the extended leg of the patient so that the outer side of the patient's leg along the shin region rests on thefirst recess35 of thebasin30 and the outer side of the patient's foot rests on thesecond recess36 of thebasin30.
• In another embodiment, the[0160]basin30, as described above, can optionally comprise athird recess36′ disposed along theupper periphery34 opposite thesecond recess36, as illustrated by the dashed lines in FIG. 5.

Thefirst recess35 can be configured to receive, for example, an upper arm portion. Accordingly, thebasin30 can be used for irrigating wounds on the knee area and the elbow area of the human anatomy. Optionally, thefirst recess35 can be configured to receive a human foot, so that thebasin30 can be used for irrigating wounds on the knee area and the ankle area of the human anatomy.
• In another embodiment, the[0162]basin30 can optionally comprise afourth recess35′, disposed along theperiphery34 opposite thefirst recess35. Thefourth recess35′ has the same general structure as thefirst recess35 and would be identified with similar reference numerals (not shown).

Therecesses35,36,35′,36′ can also optionally be sized such that only two of therecesses35,36,35′,36′ share the same dimensions. In another example, therecesses35,36,35′,36′ can be sized such that only three of the fourrecesses35,36,35′,36′ share the same dimensions. In still another example, therecesses35,36,35′,36′ can each have different dimensions. As used herein, the dimension of a recess includes the breadth and depth of the recess. For example, the depth of the first recess is the difference between themaximum height32dand theminimum height32eof thefirst recess35.

The recessededge56ais recessed downward relative to theupper edge54. In the illustrated embodiment, thejunctures54bthat connect theupper edge54 to the recessededge56ahave a contoured shape. For example, thejunctures54bare curved to provide a continuous transition between the recessededge56aand theupper edge54. However, the junctures can have any number of shapes, such as, but without limitation, a step shape as illustrated by the dashed line in FIG. 8.
• The[0193]basin50 further comprises aninner edge56bformed on the inner surface52aand disposed between thejunctures54b. Theinner edge56bis recessed downward relative to theupper edge54 as illustrated in FIGS. 9 and 10. Theinner edge56bmay optionally also be recessed downward relative to the recessededge56aas illustrated in FIG. 9. In the illustrated embodiment, thejunctures54bthat connect theupper edge54 to theinner edge56bhave a contoured shape to provide a continuous transition between theinner edge56band theupper edge54. However, thejunctures54bcan have any number of shapes as discussed above.
• The recessed[0194]edge56aand theinner edge56bdefine acontact region57 that extends between theedges56a,56b. In the illustrated embodiment, thecontact region57 is an outwardly extending flange having a width57a, supported only by the connection between the recessededge56ato thewall52. In another option, theinner edge56bjoins thecontact region57 to theouter surface52band the contact-region57 is supported only by the connection between theinner edge56bto thewall52. Thecontact region57 is recessed downward relative to the upper edge,54, as shown in FIG. 9, and is configured to receive, for example, a human hip. Moreover, thecontact region57 is preferably configured to receive the human anatomy from a point above the hip to a point below the buttock. Thecontact region57 is also preferably horizontal. As used here, horizontal means substantially at zero degrees relative to the resting surface. However, thecontact region57 can optionally be inclined inwardly so as to drain liquid falling on thecontact region57 back into thecavity53, as shown in FIG. 9.
• The[0195]wall52 defines amaximum height52dalong the periphery of thewall52. Themaximum height52dis defined as the distance from the resting surface to theupper edge54 of thewall52. Thewall52 also defines aminimum height52edefined as the distance from the resting surface to theinner edge56b. Theheights52d,52eare configured to be sufficiently large to allow thecavity53 defined by thewall52 and the base51 to hold a substantial volume of fluid.
• As described above with respect to the[0196]basin10, theconvertible portion59 can similarly comprise a variety of structures and combination of structures. Moreover, a plurality ofconvertible portions59 can optionally be disposed along the periphery of thewall52 and thebase51. For example, but without limitation, theconvertible portion59 can comprise ahole59 formed on thewall52 covered with a removable cover, such as, but not limited to, a peel-off seal. The cover can be attached to theouter surface52b, for example, with an adhesive.
• In another example, the[0197]convertible portion59 can comprise a threadedhole59 formed on thewall52 with a threaded plug that covers thehole59. In still another example, a removable cork can be used to cover thehole59.
• In yet another example, the[0198]convertible portion59 can comprise anipple59 having a removable cap, thenipple59 extending outward from theouter surface52b. Thenipple59 can be molded onto theouter surface52b. Optionally, thenipple59 can be removably screwed onto theouter surface52b. In another example, theconvertible portion59 can comprise anipple59 having a strainer and a removable cover, such as, but not limited to a peel-off seal.
• In still another example, the[0199]convertible portion59 can comprise aclamp59 configured to receive a suction hose, such as a conventional suction hose found in a medical facility, where theclamp59 is integrally molded or removably attached to the inner surface52aof thebasin50. In another example, theconvertible portion59 can comprise a removable holder having at least one clip disposed over thewall52 of thebasin50.
• According to the illustrated embodiment of the[0200]basin50, theconvertible portion59 is preferably in the form of an annularly extendingscore59 defining a frangible portion disposed on thecurved region55a. However, thescore59 can be disposed on any portion of thewall52 or thebase51. Additionally, a plurality ofscores59 can optionally be disposed on thebasin50. Thescore59 is configured to form an aperture through thewall52 orbase51 to drain thecavity53 following the removal of the material bounded by thescore59 from thewall52. Thescore59 is preferably disposed near the bottom of thecurved region55a, close to the resting surface. However, thescore59 may be disposed in any location capable of providing an effective drain for thecavity53 upon the removal of the material bounded by thescore59 from thewall52. Additionally, though thescore59 preferably comprises a circular shape, as shown in the illustrated embodiment, thescore59 can comprise any shape that provides an effective drain for thecavity53. For example, thescore59 can comprise a slit.
• In preparation for the irrigation of a hip wound, medical personnel have the patient lay on their side on the examination table so that the wound on the hip faces away from the table. Personnel then place the[0201]basin50 adjacent the patient's hip so that the hip rests on thecontact region57 from a point above the hip to a point below the buttock. Accordingly, thecontact region57 receives the injured hip and the wound faces toward thecavity53. Personnel then direct irrigation fluid with an irrigation device to the wound region to remove any contaminants from the wound region. Because thecontact region57 is recessed relative to theupper edge54, theupper edge54 advantageously acts as a shield during the irrigation procedure, effectively directing irrigation fluid toward thecavity53. The irrigation fluid directed to the wound region subsequently collects in thecavity53 of thebasin50.
• If medical personnel wish to actively drain the[0202]basin50 during the irrigation procedure, personnel modify theconvertible portion59, as described above with respect to thebasin10, to create a drain in thebasin50. Thebasin50 is then ready to be actively drained. In the illustrated embodiment, where theconvertible portion59 comprises afrangible portion59, personnel can break thefrangible portion59 to create a drain for thebasin50. Personnel can optionally insert a draining device, such as thegrommet20, into the drain and attach a suction hose to the draining device. Personnel can then attach a second end of the suction hose to a suction device to actively drain thebasin50. As noted above, thebasin50 can comprise a plurality ofconvertible portions59 disposed along the periphery of thebasin50, allowing personnel to choose theconvertible portion59 that best accommodates the draining of thebasin50 or create additional drains.
• Medical personnel can also actively drain the[0203]basin50 by attaching the adhesive surface5aof thecannula5 to the inner surface52aof thebasin50 such that an end of thecannula5 is proximal to thebase51. Optionally, thecannula5 is configured to self-support against the inner surface52aof thebasin50 without an adhesive surface. Personnel can then attach a second end of thecannula5 to a suction device, as described above.
• With reference to FIG. 11, an[0204]irrigation basin60 for irrigating a wound on a human anatomy is illustrated therein. For example, thebasin60 can be used for irrigating a wound on a lower arm region or a lower leg region of the human anatomy. Thebasin60 comprises a base61 having a generally rectangular shape and aperipheral wall62. Thebasin60 can have other shapes, such as, but without limitation, round, oval, kidney, and square. Thewall62 is preferably substantially at ninety degrees relative to a resting surface upon which thebasin60 rests. Thebase61 and thewall62 define acavity63 in the center of thebasin60. Theperipheral wall62 also defines aninner surface62afacing toward thecavity63 of thebasin60 and anouter surface62bfacing away from thecavity63 of thebasin60. Thebasin60 also comprises anupper periphery64 having aninner edge64aand anouter edge64b. Theouter edge64bjoins theupper periphery64 to theouter surface62b. In the illustrated embodiment, theperiphery64 defines an inwardly extending flange having awidth62c, supported only by the connection between theouter edge64bto thewall62. Alternatively, the thickness of thewall62 can be sufficient to form theperiphery64. In another option, theinner edge64ajoins theupper periphery64 to theouter surface62band theperiphery64 is supported only by the connection between theinner edge64ato thewall62.
• The[0205]basin60 is preferably made of a hard plastic material. For example, but without limitation, thebasin60 can be made of polyurethane or polypropylene, among other materials. The material is preferably biocompatible and hypo-allergenic. Thebasin60 can also be made of metal, such as, but without limitation, stainless steel. Additionally, thebasin60 is preferably sterilized for use in medical procedures. Thebasin60 can optionally be re-useable.
• The[0206]basin60 comprises arecess65 configured to receive a human extremity. For example, therecess65 can be configured to receive a human forearm to irrigate a wound located below a human elbow. In another example, therecess65 can be configured to receive a human calf to irrigate a wound located below a human knee. Therecess65 is disposed along theupper periphery64 at one end of thebasin60 and bisects theouter surface62band theinner surface62a. Therecess15 joins to theupper periphery14 atedges14c.
• The[0207]basin60 also optionally includes at least oneconvertible portion69 disposed on theouter surface62bof thewall62 near the bottom edge of thebasin60, where the bottom edge is the edge that contacts the resting surface. Oneconvertible portion69 is shown in the illustrated embodiment. Theconvertible portion69 can optionally be disposed on thebase61. In one example, theconvertible portion69 can be centrally disposed on the bottom of thebase61.
• As shown in FIG. 11, the[0208]base61 of thebasin60 is generally horizontal relative to the resting surface and rectangular in shape. Moreover, thebase61 is substantially at zero degrees relative to the resting surface. However, thebase61 of thebasin60 is not limited to the rectangular shape or to being parallel to the resting surface. For example, thebase61 may be inclined at an angle greater than zero degrees and configured to direct irrigation fluid on the base61 in the direction of theinner surface62anearest to theconvertible portion69. For example, thewall62 can include downwardly protruding portions (not shown) which raise anend67arelative to anend67b. Alternatively, thebase61 can be mounted to thewall62 such that the end of the base61adjacent end67ais higher than the end of the base61adjacent end67b. In another example, thebase61 can be configured to be adjustably inclined to a plurality of angles such that the end of the base61adjacent end67ais higher than the end of the base61 adjacent theend67b.
• The[0209]peripheral wall62 defines a thickness, which preferably is uniform along the periphery of thewall62. The thickness is configured to provide thewall62 with adequate structural rigidity to prevent excessive flexing of thewall62. Accordingly, the thickness can optionally have various sizes, each of which is capable of providing thewall62 with adequate structural rigidity. For example, the thickness can be between 1 mm and 5 cm.
• The[0210]wall62 defines amaximum height62dalong the periphery of thewall62. Themaximum height62dis defined as the distance from the resting surface to theupper periphery64 of thewall62. Thewall62 also defines aminimum height62eat theend67bof the basin. Theminimum height62eis defined as the distance from the resting surface to a minimum point65aof therecess65. Theheights62d,62eare configured to be sufficiently large to allow thecavity63 to hold a substantial volume of fluid.
• The[0211]upper periphery64 in the illustrated embodiment is generally parallel to the resting surface. However, theupper periphery64 can optionally be inclined inwardly so as to drain liquid falling on theperiphery64 back into thecavity63. Additionally, theperiphery64 can have a curved surface so that theperiphery64 does not have theedge64bto provide a seamless junction between theupper periphery64 and theouter surface62b.
• The[0212]recess65, as illustrated in FIG. 11, extends from theedges64cof theupper periphery64 to the minimum point65a. Moreover, therecess65 has a curved shape. However, therecess65 may optionally have any contoured shape configured to receive a human extremity. Accordingly, therecess65 is not limited to the arcuate shape illustrated in FIG. 11. Therecess65 further comprises arecess surface65band edges65c,65d. Therecess65 preferablyjoins to thewall62 at theedge65d. Optionally, therecess65 can join to thewall62 at theedge65c. In the illustrated embodiment, therecess surface65bextends horizontally from theedge65cto theedge65dadjacent theouter surface62b. Therecess surface65bcan optionally be curved between theinner surface62aand theouter surface62bto provide a seamless junction between thesurface65band thesurfaces62a,62bwithout theedge65d. Therecess surface65bcan also optionally be inclined inwardly so as to drain liquid falling on thesurface65bback into thecavity63. Therecess65 may also have a contoured juncture with theupper periphery64 to provide a seamless junction between therecess surface65band theupper periphery64, without theedges64c.
• As described above with respect to the[0213]basin10, theconvertible portion69 can similarly comprise a variety of structures and combination of structures. Moreover, a plurality ofconvertible portions69 can optionally be disposed along the periphery of thewall62 and thebase61. For example, but without limitation, theconvertible portion69 can comprise ahole69 formed onwall62 covered with a removable cover, such as, but not limited to, a peel-off seal. The cover can be attached to theouter wall62b, for example, with an adhesive.
• In another example, the[0214]convertible portion69 can comprise a threadedhole69 formed on thewall62 with a threaded plug that covers thehole69. In still another example, a removable cork can be used to cover thehole69.
• In yet another example, the[0215]convertible portion69 can comprise anipple69 having a removable cap, thenipple69 extending outward from theouter wall62b. Thenipple69 can be molded onto theouter wall62b. Optionally, thenipple69 can be removably screwed onto theouter wall62b. In another example, theconvertible portion69 can comprise anipple69 having a strainer and a removable cover, such as, but not limited to a peel-off seal.
• In still another example, the[0216]convertible portion69 can comprise aclamp69 configured to receive a suction hose, such as a conventional suction hose found in a medical facility, where theclamp69 is integrally molded or removably attached to theinner surface62aof thebasin60. In another example, theconvertible portion69 can comprise a removable holder having at least one clip disposed over thewall62 of thebasin60. In another example, the convertible portion can comprise an aperture on theupper periphery64 configured to receive a cannula.
• According to the illustrated embodiment of the[0217]basin60, theconvertible portion69 is in the form of an annularly extending score defining a frangible portion disposed on theouter surface62b. However, thescore69 may be disposed on any portion of thewall62 or thebase61. Additionally, a plurality ofscores69 can optionally be disposed on thebasin60. Thescore69 is configured to form an aperture through thewall62 orbase61 to drain thecavity63 following the removal of the material bounded by thescore69 from thewall62. Thescore69 is preferably disposed near the bottom of thesurface62b, close to the resting surface. However, thescore69 can be disposed in any location capable of providing an effective drain for thecavity63 upon the removal of the material bounded by thescore69 from thewall62. Additionally, though thescore69 preferably comprises a circular shape, as shown in the illustrated embodiment, thescore69 can comprise any shape that provides an effective drain for thecavity63. For example, thescore69 can comprise a slit.
• In preparation for the irrigation of a wound on a human extremity, if the wound is located below the patient's elbow, medical personnel place the[0218]basin60 below the patient's arm such that the patient's forearm rests on therecess65. Alternatively, if the wound is located below the patient's knee, personnel place thebasin60 below the patient's leg such that the patient's calf rests on therecess65. Accordingly, the patient's wound is disposed over thecavity63 of thebasin60.
• If personnel wish to actively drain the[0219]basin60 during the irrigation procedure, personnel modify theconvertible portion69, as described above with respect to thebasin10, to create a drain in thebasin60. Thebasin60 is then ready to be actively drained. In the illustrated embodiment, where theconvertible portion69 comprises afrangible portion69, personnel can break thefrangible portion69 to create a drain for thebasin60. Personnel can optionally insert a draining device, such as thegrommet20, into the drain and attach a suction hose to the draining device. Personnel can then attach a second end of the suction hose to a suction device to actively drain thebasin60. As noted above, thebasin60 can comprise a plurality ofconvertible portions69 disposed along the periphery of thebasin60, allowing personnel to choose theconvertible portion69 that best accommodates the draining of thebasin60 or create additional drains.
• Medical personnel can also actively drain the[0220]basin60 by attaching the adhesive surface5aof thecannula5 to theinner surface62aof thebasin60 such that an end of thecannula5 is proximal to thebase61. Optionally, thecannula5 is configured to self-support against theinner surface62aof thebasin60 without an adhesive surface. Personnel can then attach a second end of thecannula5 to a suction device, as described above.
• Irrigation fluid is then directed to the wound region to remove any contaminants from the wound region. The irrigation fluid directed to the wound region subsequently collects in the[0221]cavity63 of thebasin60. Therecess65 advantageously improves the fluid-collection ability of thecavity63 by reducing escape of irrigation fluid through the juncture of the extremity with therecess65.
• With reference to FIG. 12, an[0222]irrigation shield70 is illustrated therein. Theirrigation shield70 comprises asheet71 and anaperture73 disposed at a central portion of thesheet71. Theaperture73 is configured to be stretched from a resting state to an enlarged state. Thesheet71 is flexible and thus can be shaped to define anopen end74.
• An[0223]elastic member73bpreferably attaches circumferentially to thesheet71, around theaperture73 and is configured to be modified from a resting state to an enlarged state for use with an irrigation device such as the one disclosed in U.S. Pat. No. 6,156,004, discussed below. Themember73bis further configured to generate a gripping force. In the illustrated embodiment, theelastic member73bis an elastic band. Theelastic member73bcan optionally be a latex portion attached circumferentially around theaperture73, the latex portion having an elastically enlargeable opening configured to receive the irrigation device. Themember73bis preferably attached to thesheet71 with glue. However, themember73bcan be attached to thesheet71 in a number of ways, such as, but without limitation, by being sewn to thesheet71.
• The[0224]sheet71 is preferably transparent and made of a flexible material. For example, thesheet71 can be made of polyurethane or polypropylene. In the illustrated embodiment, the sheet defines an umbrella shape extending along anaxis72 and has a plurality ofpleats75 extending between theaperture73 at thelongitudinal end72aand theopen end74 at thelongitudinal end72b. However, thesheet71 can optionally have nopleats75. Moreover, thesheet71 is not limited to defining an umbrella shape, but can define one of a variety of shapes. For example, but without limitation, thesheet71 can define a circular shape, a square shape, a rectangular shape, a star shape, a diamond shape, and a half-circle shape.
• The[0225]sheet71 comprises alength76 defined as the distance between theaperture73 at thelongitudinal end72ato theopen end74 at thelongitudinal end72b. Thelength76 is preferably four feet. Thelength76 of thesheet71 can optionally be shortened, for example with scissors, as desired during an irrigation procedure. Thesheet71 also comprises a thickness77. The thickness77 may be any thickness that adequately provides thesheet71 with the necessary flexibility, and allows thesheet71 to be folded compactly to fit in the cover2 of thekit1. For example, the thickness77 preferably is from 0.001 inch to 0.02 inch.
• A[0226]typical irrigation device80 is illustrated in FIG. 13. Thedevice80 comprises anirrigation handpiece81, and asuction irrigation tip82 that is detachably connected to thehandpiece81. Thehandpiece81 is connected to a suction source83 through aflexible suction tubing84, and to anirrigation source85 throughflexible irrigation tubing86. Asuction lumen87 and anirrigation lumen88, both shown in phantom, extend through the entire length of thehandpiece81. Thesuction lumen87 connects to the suction source83 at one end and to asuction port89 at a second end. Theirrigation lumen88 connects to theirrigation source85 at one end and to anirrigation port90 at a second end. Bothports89,90 are formed in a fitting91 at the distal end of thehandpiece81.
• When the[0227]tip82 is connected to thehandpiece81 and thehandpiece81 is energized, irrigation fluid passes through theirrigation port90 and into thetip82. The irrigation fluid is emitted from adistal end92 of thetip82 at a frequency controlled by thehandpiece trigger93. Thetip82 includes aflexible splash shield95 andconnector96. Theconnector96 is disposed at aproximal end94 of thetip82 and detachably connects thetip82 to thehandpiece81. Theflexible shield95 includes aproximal collar97 and a conical body that diverges in a distal direction to adistal rim98. Thecollar97 is slidably mounted to anirrigation tube99 comprised by thetip82. Vent holes100 disposed on theshield95 are configured to prevent the shield from collapsing when theirrigation device80 is operated in a suction mode. Astop ridge102 may circumscribe the proximal end of theirrigation tube99 to prevent thesplash shield95 from being retracted into contact with theconnector96.
• During operation, medical personnel connect the[0228]handpiece81 to thetip82 and fit therim98 of theshield95 through theaperture73 in its enlarged state so that theelastic member73bpreferably rests around thecollar97. Theelastic member73bpreferably generates a gripping force on the collar to substantially prevent theelastic member73bfrom sliding along thecollar97. Personnel optionally shorten thelength76 of thesheet71 as desired. For example, personnel can cut the sheet71adesired distance circumferentially around theaxis72. Medical personnel preferably cut thesheet71 with scissors, but may optionally use any sharp object.
• Medical personnel then place the[0229]open end74 of thesheet71 so that it is disposed over the wound region of the patient. For example, if the wound is on the knee-area, as discussed above, personnel can place thesheet71 over the injured leg of the patient so that it covers the wound area and thebasin10. Personnel then actuate the irrigation device by pressing thetrigger93 to emit irrigation fluid from thetip82. Irrigation fluid is then directed to the wound area of the patient, which is then collected in the basin.
• It is to be noted that the illustrated[0230]irrigation device80 is merely an example of irrigation devices used in the surgical arts. Theaperture73 can be sized to fit over and engage any type of irrigation device, including those without a suction or aspiration feature, and those with different sizes and types of splash shields, or with or without a splash shield.
• With reference to FIGS. 14-20, a prior art suction system is described below with reference to FIGS. 14-19. An improved suction hose is illustrated in FIG. 20, in section view and identified generally by the[0231]reference numeral5′.
• With reference to FIG. 14, a typical suction system used in an operating room includes a[0232]suction source110, asuction hose112 having a first end connected to the suction source and asecond end114 which includes a female adapter configured to releasably engage a fluid anddebris collection device116.
• The fluid and[0233]debris collection device116 is typically in the form of aglass jar118 having alid120. Thelid120 includes aconnector122 configured to create a seal with theadapter114. Thelid120 typically includes at least oneother adapter124 that is configured to connect with a female connector typically included with suction hose typically used in an operating room.
• FIG. 15 shows an enlarged side elevational view of a[0234]female connector126 connected to an end ofsuction hose128. Thesuction hose128 has aninner diameter130 of about 6 millimeters. Theouter diameter132 of thehose128 is about 9 millimeters.
• The[0235]female adapter126 includes a—firstannular recess134 that is configured to mate with the outer surface of thetubing128. Thefemale adapter126 also includes astop member136 that is configured to abut the inner end of thehose128. Theinner surface138 of thestop136 is sized so as to define an inner diameter that is approximately equal to theinner diameter130. Thefemale adapter126 also includes aninner recess140 that is configured to receive the adapter124 (FIG. 14). The opposite end of thehose128 can include another female adapter similar or identical to the female adapter0.126.
• As shown in FIG. 16, a[0236]suction device142 which is commonly used in medical procedures, includes aninlet end144 and adischarge end146. Theinlet end144 includes a plurality ofopenings148, opening into aninner lumen150. Theopenings148 are sized to prevent large clumps of tissue and bone chips from entering thelumen150. For example, one known suction device includes openings that are about 4 m long and 1-2 mm wide.
• The[0237]lumen150 extends along the length of thesuction device142 and terminates at adischarge146. Thedischarge146 is configured to fit into a recess of a female adapter such as therecess140 in the female adapter126 (FIG. 15).
• In an operation, the[0238]vacuum hose128 connects thesuction device142 with theadapter124 of thedebris collector116. With thesuction source110 activated, a vacuum is created in the interior of thecollection device116, thereby drawing a vacuum through theadapter124, through thevacuum hose128 and through thesuction device142. As such, fluid and debris is drawn through theapertures148, through thelumen150, through thehose128 and into the interior of thecollection device116. Because theadapter122 is mounted to thelid120, the fluid and debris collected within the jar-I18 does not enter thehose112 or thesuction source110.
• However, it has been found that the[0239]suction hose128 that is typically used im operating rooms can become clogged more easily than thesuction device142. Further, it is also been found that clogs within thesuction hose128 can be initiated at deformed portions of thehouse128.
• For example, with reference to FIG. 17, a[0240]suction hose kit152 is illustrated therein and includes a sterilizedpackage154 and thesuction tubing128. It has been found that suchconventional suction tubing128 can become deformed. For example, some portions ofsuch suction tubing128 remains round in sections.
• As shown in FIG. 18, the cross-sectional shape of the[0241]tubing128 in certain areas remains round. However, as shown in FIG. 19, certain portions of thetubing128 can become constricted. This deformation can sometimes be found in the curve of thetubing128 that has been folded for packaging purposes so that thetubing128 fits within thepackage154. Additionally, various portions of thetubing128 can include indentations that may have been formed by machines used to manufacture thetubing128 or from the weight of other articles stacked on top of thepackage154 during stocking. Regardless of the mechanism causing such deformation, aninner dimension156 of the deformed portion of thetube128 can become sufficiently restricted that the likelihood of clogging at the deformed portion is increased.
• Thus, in accordance with an aspect of at least one of the inventions disclosed herein, a[0242]suction tubing5′ illustrated in FIG. 20 includes an inner diameter of at least about 8 millimeters. More preferably, the inner diameter of thetubing5′ is from about 8 millimeters to about 15 millimeters.
• As such, the[0243]tubing5′ can include the same type of deformations occurring in the knownsuction tubing128, yet retain a sufficient clearance within its inner dimension that the likelihood of clogging is not-increased as greatly as that resulting from the deformed portions of thetubing128 illustrated in FIG. 19. For example, were thesuction tubing5′ is formed with an inner diameter of about 8 millimeters in a relaxed state, thesuction tubing5′ can be deformed to some extent resulting in a minimum inner dimension identified by thereference numeral158. Because the diameter of thesuction tubing5′ in a relaxed state is at least 8 millimeters, the reducedinner dimension158 caused by a deformation can still be as large as 6 millimeters. Thus, where thetubing5′ has been damaged or deformed in the same manner as the knowntubing128, thetubing5′ is less likely to cause clogging in the same manner as the knowntubing128.
• Optionally, the[0244]tubing5′ can include the samefemale connectors126 described above with reference to FIG. 15. However, such female adapters can also include slight modifications to theinner recess134 so as to more readily accept the outer diameter of thetubing5.
