FIELD OF THE INVENTIONThe present invention relates to a toilet attachment for enema, douche or colonic irrigation, and more particularly to a toilet attachment that can be removed fast and easily and allows hygienic use. The present method further relates to a method for applying such a toilet attachment.
BACKGROUND OF THE INVENTIONColonic irrigation is used to remove the plaster-like fecal coating that sometimes forms on the walls of the colon. In such cases enemas are not effective to dissolve the coating. Furthermore, to remove this coating too rapidly would cause the inner lining of the colon to become “raw” and painful. For removal, the fecal coating in the colon must be thoroughly soaked and saturated with water so that its removal can take place gradually and comfortably. This gradual removal can be accomplished by a series of colon irrigations in which many gallons of water, several ounces at a time, are introduced into the colon through the rectum. The water is expelled after each introduction, requiring an apparatus to contain the expelled liquid until it can be safely discarded, or requiring apparatus to guide the expelled water into a disposal container. This apparatus is expensive, bulky and awkward to use in a home environment, especially as home colonic equipment often includes boards on which a person lies in a reclined position during the irrigation. Further, the volume of water involved makes it difficult to perform colonic irrigation in the home while remaining clean.
Additionally, if the irrigating tube is inserted improperly into the rectum, the irrigation may be ineffective, or harmful. The rectal tip of the irrigation device should never go into the rectum over 2.5 to 3 inches. Colon perforation, sepsis and possible injury of the anal canal of rectum may result with a misdirected or inadequately lubricated tip.
Further, enemas also introduce water into the colon through the rectum, although the volume of water used is much less. As enemas are preferably performed while lying on a person's side, with the water being expelled while sitting, cleanliness and convenience are typically compromised. Thus, the same or similar concerns on cleanliness, convenience and safety exist. Likewise, for a douche water is also introduced into a body cavity in small amounts, yet similar concerns exist as to the safety, convenience and cleanliness
There is thus a need for a simple irrigation device that may be used safely and cleanly to irrigate body cavities in the home.
SUMMARY OF THE INVENTIONAn aspect of the invention involves a toilet attachment that can be positioned between a toilet seat and a toilet bowl and can be connected to a fluid line. The toilet attachment comprises a tubular irrigation assembly and a base plate. The base plate has an upper and lower surface, a rear end and a front end. When installed, the rear end faces a rear portion of the bowl and the front end faces a front portion of the bowl. The base plate has ports to receive and secure the fluid line and the irrigation assembly. At least one of these ports is located at the front end. The toilet attachment can easily be attached to and removed from a toilet to store the toilet attachment when it is not in use. The irrigation assembly and the fluid line can be removed from the base plate, which allows easy cleaning and replacement of parts that get into contact with a user's body and/or a user's fluids or excrements.
A further aspect of the invention involves a toilet attachment having a safety feature. The toilet attachment comprises an irrigation assembly with an irrigation tip and a means for preventing insertion of the irrigation tip into a user's body cavity beyond a predetermined distance. This means is disposed on the assembly at a preset distance from the tip. The means may have a variety of shapes, e.g., a double “L” shape, a lateral “U” shape, or a lateral “S” shape. The means is sized to prevent easy or unintentionally insertion into a rectum or vagina. The various embodiments of the safety feature further adds flexibility to the irrigation assembly to allow a user more mobility and provide for more comfort than a hard tube.
Another aspect of the invention involves a toilet attachment comprising an L shaped tube to be attached to a base plate which can be positioned between a toilet seat and a toilet bowl. The L shaped tube is to be connected to a fluid line. The toilet attachment further comprises a tubular irrigation assembly having an irrigation tip and a generally U shaped form, and a means for preventing insertion of the irrigation tip too far into a user's body cavity as described above. The L shaped tube has a first end to connect to the fluid line, and a second end to receive a connecting end of the irrigation assembly. The base plate has an upper and lower surface, a rear end and a front end. When installed, the rear end faces a rear portion of the bowl and the front end faces a front portion of the bowl. The base plate has a hole in proximity to the front end to receive a portion of the L shaped tube, and brackets attached on the upper surface of the base plate to secure the tube. The irrigation assembly is connected to the portion of the tube that is fed through the hole. The L shaped tube can be easily removed from and attached to the flat base plate making the attachment particularly portable.
A still further aspect of the invention involves a method for applying a toilet attachment for irrigating a body cavity. The method places a support between a toilet bowl and a toilet seat to hold a fluid connector, and removably connects a fluid source to one end of the fluid connector. The method further removably connects an irrigation assembly to the fluid connector so fluid from the source can flow to the irrigation tip, and provides the irrigation tip with at least one portion that changes the direction of the fluid flow by at least 90°. One portion is located not more than about three inches from a distal end of the irrigation tip to limit insertion of the tip into a user's body cavity.
Another aspect of the invention involves an irrigation assembly suitable for a toilet attachment. The assembly comprises a tubular body having a first and second end. The first end is open, and can be removable attached to a base plate of the toilet attachment so that fluid can be fed to the assembly. The assembly further comprises an irrigation tip and a means for limiting insertion of the tip. The tip is positioned at the second end of the tubular body, and the means is disposed on the tubular body at a preset distance from the irrigation tip for limiting insertion of the tip into a user's body to a preset maximum distance. The irrigation assembly is removable attachable to the base plate so that various users may use the same base plate and change only the irrigation assembly which is partly inserted into a body cavity.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTFIG. 1 shows an overview of a conventional toilet with an installed toilet attachment for enema, douche or colonic. The toilet comprises atoilet bowl10 and awater reservoir14 in water communication with thetoilet bowl10 for flushing thetoilet bowl10 after use. Atoilet seat12 is attached to thetoilet bowl10 in a conventional hinged manner. The toilet attachment is positioned between thetoilet seat12 and arim30 of thetoilet bowl10, and comprises a base plate28 (only partly visible in FIG.1), atubular irrigation assembly24 and afluid line20.
Thefluid line20 provides for fluid communication between afluid reservoir18 and theirrigation assembly24, subsequently referred to as the rectal assembly, which may be partly inserted into the rectum or vagina for use. Preferably thefluid reservoir18 is placed at an elevated location so that gravity determines the fluid pressure. In a bathroom of a private home, the elevated location can be achieved by simply placing thefluid reservoir18 on top of thewater reservoir14, and as needed, on top of anadditional support16. The height ofsupport16 can be varied to adjust the gravity controlled fluid pressure through thefluid line20. Thefluid reservoir18 may also be a bag which can be attached to a wall or ceiling by means of a hook. The location of the hook and bag can again adjust the fluid pressure. Such a bag, e.g., is used for camping or other outdoor activities to store water. AU-shaped tube26 connects thefluid line20 to thefluid reservoir18. Aclamp22 is disposed on thefluid line20 and allows the flow of fluid to be manually controlled, with theclamp22 preferably being resiliently urged into a closed or no-flow position.
The fluid may be water or an aqueous solution comprising, e.g., a therapeutical composition. The fluid may be heated within thefluid reservoir18 or may be filled into thefluid reservoir18 at room or body temperature.
Thefluid line20 can be an one-piece line or a line comprising two or more interconnected pieces. Preferably, thefluid line20 is made of a flexible material, e.g., a conventional hose. If thefluid line20 comprises two or more pieces different materials may be used having differing flexibilities as appropriate to the use of each piece.
As an alternative to thefluid reservoir18, thefluid line20 can be attached to a faucet. In this case, a suitable connector is attached to thefluid line20 to ensure a reliable water tight connection. For safety reasons, a pressure regulator is required when thefluid line20 is connected to a faucet.
FIG. 2A is a schematic illustration of the toilet attachment positioned on top of a toilet bowl. Thetoilet seat12 is lifted to allow a better view of the toilet attachment positioned on top of the bowl'srim30 at the back of thebowl10 towards thewater reservoir14.FIG. 2A also allows a better view of therectal assembly24 which will be described in more detail in connection with FIG.2B andFIGS. 4A-4F.
Thebase plate28 of the toilet attachment is secured to the toilet by being located between thetoilet seat12 and thebowl10, and by having a depending portion29 (FIGS. 2B and 3) depending into thebowl10 and configured to rest against the curve of thebowl10. As no further attachment means are required, thebase plate28 and its dependingportion29 are therefore the whole toilet attachment. The attachment can be easily installed and removed, e.g., for cleaning to ensure hygienic conditions. The shape ofbase plate28 is advantageously adapted to the contour of therim30 at the back of thebowl10 and does not significantly extend from underneath thetoilet seat12. In the illustrated embodiment of thebase plate28, thebase plate28 has a flat, curved form. The opening of thetoilet bowl10 is therefore only minimally reduced when thebase plate28 is installed. Thebase plate28 has a rear end that, when installed, faces thewater reservoir14, and a front end that, when installed, faces the front of thetoilet bowl10.
Except for the dependingportion29 that extends inside therim30 of thebowl10, thebase plate28 has a thickness that is about equal to a distance between therim30 and thetoilet seat12 when thetoilet seat12 is lowered. This distance is determined by the height ofspacers40 usually attached to atoilet seat12. If the thickness is about equal to, or very slightly greater than this distance, then the weight of a user sitting on theseat12 will trap thebase plate28 between therim30 andseat12 to help hold thebase plate28 in position.
Thebase plate28 holds therectal assembly24 in a substantially vertical position and provides for a reliable connection between therectal assembly24 and thefluid line20. Preferably, thefluid line20 and therectal assembly24 are both attached to the front end of thebase plate28 within the depending section of thebase plate28. In another embodiment (not shown) of the attachment, thefluid line20 may be attached to the rear end of thebase plate28. As noted above, the dependingportion29 may be thicker than remaining portions of thebase plate28, which have to fit between therim30 and thetoilet seat12. Thefluid line20 is also positioned between therim30 and thetoilet seat12 without being significantly compressed so as to restrict fluid flow through theline20.
FIG. 2B shows a magnified portion of abase plate28 and arectal assembly24 to illustrate an example for attaching thefluid line20 and therectal assembly24 to thebase plate28. In a plane parallel to an upper surface of thebase plate28, the upper surface facing thetoilet seat12, thebase plate28 has a channel or groove36 with two ends orports46,48. Thechannel36 extends in the plane parallel to the upper surface. In the illustrated embodiment of thebase plate28, thechannel36 is open at the upper surface and forms aU-shaped groove36 opening onto the upper surface ofbase plate28 to allow the insertion oftube32 having an annular cross section. Within the base plate'sdependent section29, the ends46,48 face the front end of thebase plate28. Thegroove36 receives aflexible tube32 which is preferably secured in a press-fit manner to allow easy removal from thebase plate28, e.g., for cleaning or replacement of thetube32 or thebase plate28. To assist securing thetube32, the groove ends46,48 compriseprojections42,44 to narrow the diameter of thegroove36 to slightly compress thetube32 and hold it in position while not unduly restricting flow through thetube32. An end portion of thefluid line20 is removably inserted into an end34a of thetube32, with at least one of these ends being sufficiently resilient to provide a water tight connection. Insertingparts20,54 into theends34,34a also makes a tighter fit between theends34,34a and theadjacent projections42,44 to further hold thetube32 to thebase plate28.
The tubularrectal assembly24 comprises an irrigation (rectal)tip38, aU-shaped portion52 and a connectingportion50 that connects therectal tip38 and one end of theU-shaped portion52. The other end of theU-shaped portion52 is connected, at right angles to the connectingportion50, to anend portion54. Theend portion54 of therectal assembly24 is removably inserted inside anend34 of thetube32, with at least theend34 or theend portion54 being sufficiently resilient to provide a water tight connection.
Therectal tip38 contains a plurality of holes orapertures58 through which a fluid, such as water, flows. Theseholes58 may have a diameter of about {fraction (3/32)} inch and are uniformly distributed over an end portion of the connectingportion50, this end portion forms therectal tip38. Therectal tip38 may have a diameter that is equal to the diameter of the connectingportion50. In a further embodiment of therectal assembly24, thetip38 may have an enlarged bulbous shape especially suitable for a douche and for insertion into the vagina.
In a further example for attaching thefluid line20 to thebase plate28, an end portion of thefluid line20 may be inserted directly into thegroove36. In this case, thegroove36 and thefluid line20 have suitable diameters to secure thefluid line20 in the described press-fit manner. Also, the inner diameter of thefluid line20 and the outer diameter of therectal assembly24 are sized and shaped to each other to provide a releasable but water tight connection.
FIG. 3 schematically illustrates, by means of a side view of the toilet shown inFIG. 1, the use of the toilet attachment. In use, part of therectal assembly24 including therectal tip38 is inserted into a user's body. As noted above, the toilet attachment is positioned between thetoilet seat12 and thetoilet bowl10, and secured by the weight of the user, the location of the toilet attachment, and the shape of the toilet attachment. Theclamp22 is located at a suitable location on thefluid line20 to allow convenient manual control of the fluid flow from thefluid reservoir18 to therectal tip38.
If therectal tip38 is inserted improperly into the rectum, the irrigation may be ineffective, or harmful. Therectal tip38 should typically not go into the rectum over about 2.5 to 3 inches (6.4 cm to 7.6 cm). Colon perforation, sepsis and possible injury of the anal canal or rectum may result with a misdirected or inadequately lubricated tip. There is more variability for inserting thetip38 into other body cavities, with the distances set by prevailing health and safety parameters.
To guard against inserting therectal tip38 too far into the user's body, an insertion limiter56 is added to therectal assembly24 as a safety feature.FIGS. 4A-4F show various embodiments of rectal assemblies having such a limiter56. Each limiter56 provides a form of projection or restraint that limits insertion of therectal tip38 too far into the user's body. These projections or restraints can take a variety of forms as illustrated inFIGS. 4A-4F. As the body hits these projections or restraints, the insertion of therectal tip38 into the body is stopped. In most cases, the limiter56 is formed by the shape of the connectingportion50.
Thus, the projections or restraints are preferably positioned relative to thetip38 to limit the insertion of thetip38 into the appropriate body cavity, with the insertion distance limited by limiter56. In some cases, it may be desirable to vary these distances. While the previously stated lengths are preferred for the colonic application, shorter or longer dimensions may be suitable depending on the specific use of the irrigation apparatus and the person involved.
TheU-shaped portion52 of the rectal assembly24 (FIG. 2B) provides some flexibility and thus alleviates the force with which thetip38 is inserted into the rectum or other body cavity. The flexibility of therectal assembly24 made of a flexible tube enables the user to have more mobility and therefore is more comfortable than a hard tube (made of rigid plastic or stainless steel, for example). The various illustrated embodiments of the limiter56 can be formed during or after manufacture, e.g., through thermal forming the connectingportion50 into the desired shape. Thetubular connecting portion50 is advantageously a polyethylene tube ¼ inch O.D., 0.170 I.D. The connectingportion50 preferably has a diameter that is as small as possible to provide comfort, but large enough to allow sufficient fluid flow.
The limiter56, basically, is an obstacle which, besides the illustrated embodiments, could also be a wire attached to the connectingportion50. The limiter56 protects a user so that thetip38 is not unintentionally or accidentally inserted too far into the body cavity. Various shapes and configurations would be suitable to prevent therectal tip38 from being inserted too far into the rectum or vagina. The U shaped portion52 (FIG.2B), the limiter56 and therectal tip38 are preferable made of a single tube and together make up therectal assembly24.
FIG. 4A shows alimiter56a comprising a plate made of {fraction (1/16)} inch (0.16 cm) thick plastic plate. The plate is attached to therectal assembly24 at about 3 inches from therectal tip38. The plate can be glued or molded to the connectingportion50 of therectal assembly24. The plate extends orthogonal from the portion50 a distance sufficient to inhibit it from easily or accidentally entering a body cavity so that it limits insertion into such a body cavity.
FIG. 4B shows alimiter56b having a double “L” shape formed by laterally offsetting thetip38 from the main portion of the connectingportion50.
FIG. 4C shows alimiter56c having a “C” or lateral “U” shape, which extends laterally a distance sufficient to prevent easy or accidental insertion of thelimiter56c into a body cavity.
FIG. 4D shows alimiter56d in the form of a loop formed by bending the connectingportion50 into a loop. The loop has a sufficiently large diameter to prevent easy or unintentional insertion of the loop into a body cavity.
FIG. 4E shows alimiter56e comprising a ring at about 3 inches from therectal tip38. The ring is made of plastic and is {fraction (3/16)} inch thick and ½ inch in diameter. The ring's plane is parallel to the axis of the connectingportion50. The ring has a sufficiently large diameter to prevent easy or accidental insertion of the ring into a body cavity.
FIG. 4F shows a limiter56f having a lateral “S” shape. The size of the “S” prevents easy or unintentional insertion of the “S” into a body cavity.
In all the above cases, thelimiters56a-56f extend laterally from the longitudinal axis of the tip38 a distance sufficient to prevent the limiter56 from being easily or unintentionally inserted into a rectum or vagina. For practical purposes, the limiter56 is configured to prevent any insertion past the limiter56. The limiter56 is located relative to thetip38 to permit about 2.5 to 3 inches of insertion of thetip38, as previously discussed for colonic irrigation. The limiter56 may be oriented to either extend toward, or face the rear or front end of the toilet. In the illustrated embodiments, the limiter56 is placed to face the rear end of the toilet. In a further embodiment (not shown), theirrigation assembly24 may comprise a pair of limiters56 facing opposite directions. Further, as shown inFIGS. 4B,4C,4D and4F, fluid flowing in direction to theirrigation tip38 changes its flow direction at least once by at least 90°.
The illustratedlimiters56a-56f provide further flexibility to allow thetip38 to gently and resiliently contact the body. Thelimiters56b-56d and56f allow the stiffness and configuration of connectingportion50 to contribute to this increased flexibility and resilience. This reduces the force of any contact with the body to reduce the possibility of injury and to reduce the severity of any tissue injury resulting from contact with thetip38 for prolonged time periods.
Referring toFIG. 5, a further embodiment of a toilet attachment in accordance with the present invention is shown. An L shaped connectingbase tube70 may be stored on aflat base plate60 when not in use and held in place by one or moreresilient brackets62,64,66. As described above, in use, thebase plate60 is placed over a toilet bowl, between the toilet bowl and a toilet seat toward the rear of the bowl. Thebase tube70 is removed from thebrackets62,64,66 and the short end of theL tube70 inserted through ahole68 inplate60 to hold it steady and correctly orientate that end of thetube70. The longer end of theL tube70 may be held in place by thebrackets62,64,66 which are generally C shaped with one portion extending over thetube70. A connectingend72 of the tubularrectal assembly24 is inserted inside one end of thetube70, with at least one of thetubes70,72 being sufficiently resilient to provide a water tight connection. Opposite theend72 of therectal assembly24 is therectal tip38 which may be inserted into the rectum or vagina for use, as noted above. The illustratedrectal assembly24 has alimiter56c having the shape of a “C” (see FIG.4C), although any of the previously described limiters56 could be used.
The described embodiments of toilet attachments including the rectal tip may be used for enema, douche or colonic irrigation. Referring toFIG. 3, a user may advantageously lubricate therectal tip38 and anus, hold therectal assembly24 and slowly and gently insert therectal tip38 into the rectum as the user lowers himself or herself onto theseat12. Therectal tip38 should not be inserted further than the limiter (seeFIGS. 4A-4F) allows, which is typically about three inches maximum. When therectal tip38 is properly inserted, the user opens theclamp22 on thefluid line32 and proceeds with the colonic irrigation.
In a further embodiment, by placing the toilet attachment in the described manner onto a conventional toilet, the toilet can be used as a bidet. In this case, the irrigation assembly may be altered to have a shorter connecting portion50 (FIG. 2B) to position thetip38 at an appropriate location below the rim of theseat12.
The toilet attachment has a simple construction and elegant design that make this toilet attachment easy and safe to use, easy to carry and store, and very clean. The irrigation assembly can be made inexpensively thereby lowering the cost of the whole toilet attachment. The disposable irrigation assembly can be easily replaced to maintain hygienic conditions particularly if several persons use the same base plate. Since the irrigation assembly, the tube32 (FIG. 2B) and thefluid line20 can be completely removed from thebase plate28, thebase plate28 can be cleaned easily. This also allows thorough cleaning of thetube32 and eventually of the portion of thefluid line20 that extends into thebowl10.
Although an exemplary embodiment of the invention has been disclosed for purposes of illustration, it will be understood that various changes, modifications and substitutions be incorporated in such embodiment without departing from the spirit of the invention as defined by the claims which follow.
