MEDICAL INSTRUMENT HOLDER
BACKGROUND OF THE INVENTION
In recent years, increased attention has been directed by medical practitioners and the medical community as a whole to blood borne illnesses and infections. The potential for the transmission of blood borne illnesses from patients to practitioners has heightened the awareness of safety standards to protect against inadvertent practitioner infection. A variety of new safety practices and regulations have been developed dictating procedures to be followed before, during, and after surgery as well as during the routine care of patients. For example, special procedures and cautions are recommended and/or required for interactions with patients involving bodily fluids, the handling of medical apparatus that have been utilized in connection with the bodily fluids of patients; and for the disposal of bodily fluids and other biological materials. As a part of the new safety emphasis with regard to blood borne illnesses and infections, particular attention has been directed to the handling of needles, trocars, or other "sharps." Such sharps have been a subject of increased focus due to the potential for accidental puncture of the practitioner's skin and transmission of disease to the practitioner. A number of devices have been developed to protect against accidental punctures while utilizing sharps. For example, self-deploying needle shields, which can be readily actuated with limited risk of inadvertent puncturing of a practitioner, have been provided on a number of needles and other trocar type apparatus. Specialized depositories for the receipt and containment of used needles have also been developed which provide for safe and simple disposition of sharps. Another type of device which has been developed to prevent needle sticks or other punctures of a practitioner is a temporary needle holder. Such temporary needle holders are adapted to be utilized in a surgical field for holding a needle or other sharp implement that has been utilized or is intermittently utilized during the course of the procedure. Such temporary needle holders typically have a instrument holder field in which the needles can be inserted while they are not being used. The temporary needle holder provides a location for the holding of needles that are not being utilized, such that the needles are not left on the surgical surface in a manner that they may inadvertently stick or puncture the skin of a practitioner during the course of the procedure.
Typically, such temporary needle holders are configured to be fairly small. Smaller temporary needle holders are typically desired due to surgical surface ergonomics and the fact that a limited number of needles are typically utilized in a procedure. For example, typically the number and types of surgical tools, implements, and containers placed in the surgical field for use during the procedure are sufficient that a limited amount of space is available for each apparatus. Due to the limited number of needles that are utilized in typical procedures, a fairly small temporary needle holder is sufficient to hold the number of needles needed during the procedure. Because a fairly small number of needles are typically utilized and the size requirements for additional needles are quite minimal, a larger unit is typically inefficient due to unused space on the instrument holder field. Elimination of unused space on the instrument holder field typically creates greater efficiencies in usage of materials, storage/shipping size, and per unit weight.
One problem associated with such smaller and/or lighter devices is that where a practitioner is utilizing a larger needle and syringe combination or where the syringe is still partially filled with fluid, placement of the needle and syringe in the temporary needle holder can result in disadvantageous tipping of the temporary needle holder. Not only can such tipping be unpredictable, but the tipping can make it difficult to utilize the temporary needle holder and the needles and/or syringes positioned therein during the course of the procedure. Additionally, tipping of a partially filled syringe can result in turbulence in the contents of the syringe that may introduce air bubbles into the syringe. As a result, valuable surgical time may be consumed de-bubbling the syringe in preparation for injection of the contents of the syringe into the patient.
BRIEF SUMMARY OF SOME EXAMPLE EMBODIMENTS Broadly stated, embodiments of the present invention are generally concerned with devices for temporarily securing medical instruments. In one particular example embodiment, a device is provided that is configured to temporarily secure one or more medical instruments. Various optional aspects and features that may be employed in connection with the aforementioned, and other, example embodiments are addressed in the discussion of further example embodiments set forth below, and as set forth elsewhere in this application.
As suggested above, information is disclosed throughout this application concerning different possible example embodiments of the invention and various optional aspects and features that can be implemented, in various combinations and arrangements, in connection with one or more of such example embodiments. In this regard, it should be understood that yet additional embodiments are contemplated as being within the scope of the invention and, like those embodiments disclosed immediately below, can be defined by combining, in various ways, one or more of the aspects disclosed herein. Accordingly, the disclosed embodiments, including those addressed immediately below, are examples only and are not intended to limit the scope of the invention in any way. As well, nothing herein is intended, nor should be construed, to constitute either an assertion or admission that any particular disclosed aspect(s) of any embodiment of the invention constitutes a critical or essential element of such embodiment, or of any other embodiment of the invention.
With the foregoing points in mind, attention is directed now to another example embodiment of the invention. In this example, a medical instrument holder is provided that is generally configured to receive one or more needles, trocars, or other devices or implements. This example of a medical instrument holder includes one or more instrument holder fields configured and arranged to allow a practitioner to insert a needle or other sharp device into the medical instrument holder such that the needle or other sharp device can be removably retained in the medical instrument holder without effort or intervention on the part of the practitioner. One or more of the instrument holder fields may be associated with a cushion, or similar material or device, within which a portion of an inserted medical instrument can be removably retained.
In another example embodiment, a medical instrument holder is provided that is generally configured to receive one or more needles, trocars, or other sharp device or implements. This example of a medical instrument holder includes two or more instrument holder fields, at least one of which is configured and arranged to allow the practitioner to insert a needle or other sharp device into the medical instrument holder such that the medical instrument holder retains the needle or other sharp device without effort on the part of the practitioner. In this example, a boundary septum or comparable structure is provided that is configured and arranged so as to reduce the likelihood that an instrument inserted into a first one of the instrument holder fields would pass into a second one of the instrument holder fields and consequently pose a threat of injury to a practitioner or patient. The boundary septum may be positioned between at least two of the instrument holder fields, but can alternatively be configured and/or arranged in any other fashion that would reduce the likelihood that an instrument inserted into a first one of the instrument holder fields would pass into another of the instrument holder fields.

DETAILED DESCRIPTION OF SOME EXAMPLE EMBODIMENTS
As noted above, embodiments of the present invention are generally concerned with devices for temporarily securing medical instruments. Tn connection with the disclosed example embodiments, it should be noted that the terms 'temporary needle holder,' 'sharps holder apparatus,' 'medical instrument holder,' 'needle holder apparatus,' 'instrument holder/ 'temporary instrument holder' and similar terms are all employed herein in reference to devices that, in general, are configured to removably retain one or more medical instruments.
Accordingly, the use of the aforementioned terms is not intended as, nor should be construed as, a limitation on the scope of the claims.
In one example embodiment, discussed in further detail below in connection with Figure 1, a lateral surface instrument holder aperture is provided in addition to an instrument holder field in a top surface of the instrument holder aperture. Thus, smaller instruments, such as needles, can be inserted into the top surface instrument holder field. Larger medical instruments such as larger needles, partially-filled syringes, scalpels or other sharps can be positioned in the lateral surface instrument holder aperture. A portion of the instrument can rest on the support surface on which the temporary instrument holder is positioned. Resting of the instrument on the support surface minimizes tipping of the temporary instrument holder. When an instrument is positioned in the lateral surface instrument holder aperture, the instrument is positioned out of the way of movement of the practitioner, limiting disruption, damage, or breakage that may occur from the practitioner inadvertently contacting the instrument and/or instrument holder. Additionally, the unique position of the lateral surface instrument holder aperture allows a practitioner to easily and quickly identify and acquire an instrument positioned in the lateral surface instrument holder aperture.
Figure 1 is a perspective view of temporary needle holder 10, according to one embodiment of the present invention. In the illustrated embodiment, temporary needle holder 10 has a lateral surface aperture 20, which is utilized to allow for insertion of needles into the side of the temporary needle holder 10. Among other things, this arrangement may help to minimize tipping of temporary needle holder 10. In the illustrated embodiment, temporary needle holder 10 includes a top surface 12, a side surface 14, a instrument holder field 16, a lateral surface aperture 20, a boundary septum 22, a rim 24, and a bottom 26.
Top surface 12 of temporary needle holder 10 includes instrument holder field 16. Top surface 12 of temporary needle holder 10 is configured such that it is facing upward allowing it to be easily viewed and accessed by the practitioner. Targets 18 arc positioned in the instrument holder field 16 to provide a visual identification of potential placement areas for needles, trocars, or other sharp implements or tools that have been utilized during the course of the procedure. A practitioner can insert smaller and/or lighter needle apparatus, such as needle tips, emptied syringes, or an IV trocar into top surface 12.
During the course of the procedure, it is not uncommon that relatively larger medical devices such as larger needles, syringes, trocars, scalpels or other sharp implements may be utilized. Additionally, it is not uncommon that a partially filled syringe might need to be inserted into the temporary needle holder 10 during the course of the procedure. Lateral surface aperture 20 is positioned in the side surface 14 of the temporary needle holder 10 in a manner that the practitioner can insert larger and/or heavier needles and other sharp implements into the lateral surface aperture 20. Lateral surface aperture 20 provides not only a supplementary instrument holder field for insertion of sharps devices, but is also positioned relatively closer to the surgical surface, allowing the implement to rest on the surgical surface and minimize tipping of the temporary needle holder.
Boundary septum 22 is positioned adjacent a lateral side of instrument holder field 16. In one embodiment, boundary septum 22 comprises a hardened layer or other puncture impervious or puncture resistant layer, such as plastic, metal or other suitable material, configured to prevent the passage of the tips of needles, trocars, or other sharp implements from the instrument holder field to the lateral surface aperture. Boundary septum 22 minimizes migration of needle tips into adjacent instrument holder fields that may cause damage to the medical instruments. Boundary septum 22 also limits the passage of needle tips from instrument holder field 16 to lateral surface aperture 20, or from lateral surface aperture 20 to instrument holder field 16 so as to reduce the likelihood of a puncture or other break of the practitioner's skin. In this way, boundary septum 22 may prevent injury to the practitioner that might otherwise result from inadvertent contact with a sharp instrument. Rim 24 is positioned to provide an outer boundary for instrument holder field
16. Rim 24 creates a slight recess between top surface 12 of a temporary needle holder 10 and the elevation of instrument holder field 16. In this manner, rim 24 prevents inadvertent slipping of needles, sharps, or other implement from the top surface of the instrument holder field 16 to the exterior of the temporary needle holder 10. In this manner, a practitioner can safely grasp the temporary needle holder 10 and insert a needle into the instrument holder field 16. In the event that the needle slips or does not entirely puncture the instrument holder field 16, the tip of the needle will typically be caught by rim 24, preventing unexpected slipping and consequent puncturing of the skin of the practitioner. Bottom 26 is positioned on the side of temporary needle holder 10 opposite top surface 12. Bottom 26 is configured to be positioned on a surgical or other medical work surface on which the temporary needle holder 10 is to be utilized. In one embodiment, bottom 26 includes a non-slip surface or adhesive surface which facilitates contact of the temporary needle holder 10 with the surgical surface and additionally prevents tipping of the temporary needle holder 10.
As will be appreciated by those skilled in the art, a variety of types and configurations of temporary needle holder can be provided without departing from the scope and spirit of the present invention. For example, in one embodiment, a different number and configuration of targets are provided in the instrument holder field. In another embodiment, the lateral surface aperture is of a different size, shape and/or configuration than indicated in Figure 1. In another embodiment, the temporary instrument holder field may not include a boundary septum.
Figure 2 is a perspective view of the temporary needle holder 10 of Figure 1, illustrating a needle syringe combination 30 inserted into lateral surface aperture 20. In the illustrated embodiment, a syringe portion of needle syringe combination
30 is partially filled with a fluid 32. Fluid 32, positioned in the syringe portion of needle syringe combination 30, substantially adds to the weight of needle syringe combination 30. Additionally, the length of the needle portion of the needle syringe combination 30 creates a higher center of gravity, which can add to the likelihood of tipping of temporary needle holder 10 should needle syringe combination 30 be positioned or inserted in instrument holder field 16.
Additionally, a practitioner may simply desire to position needle syringe combination 30 in a separate location away from other needles or sharp implements. By providing a separate location for the insertion of needles and other sharps implements, instrument holder field 16 can also help to more readily identify needle syringe combination 30 as an implement which the practitioner may desire to utilize later in the procedure being performed.
In the illustrated embodiment, needle syringe combination 30 is inserted in lateral surface aperture 20. Needle syringe combination 30 is shown positioned at a slight angle, such that the rearward portion of needle syringe combination 30 is in contact with support surface 28. By being in contact with support surface 28, needle syringe combination 30 is sufficiently supported to prevent breakage, or other damage, of needle syringe combination 30. Additionally, needle syringe combination 30 is supported in a manner that minimizes tipping of temporary needle holder 10. In this manner, a desired and intended positioning of temporary needle holder 10 is maintained, allowing a practitioner to quickly identify instrument holder field 16 for the insertion of additional needles, sharps, or other tools or implements, and also to quickly identify the positioning of lateral surface aperture 20 and needle syringe combination 30 positioned therein.
Figure 3 is a side view of temporary needle holder 10, illustrating a top needle holder cushion layer 34 in phantom lines. It should be noted that various types of cushion layers may also be referred to herein individually and collectively as simply a 'cushion layer' or 'cushion layers,' respectively.
The positioning of top needle holder cushion layer 34 relative to lateral surface aperture 20 is also shown. As previously discussed, lateral surface aperture 20 is positioned in side surface 14 of temporary needle holder 10. Top needle holder cushion layer 34 represents the total volume of the cushion layer associated with a instrument holder field that is available to receive needles, trocars, or other sharp implements from the instrument holder field.
In the illustrated embodiment, top needle holder cushion layer 34 extends a depth into temporary needle holder 10 which at least corresponds to, and may even extend beyond, the location of lateral surface aperture 20. Boundary septum 22 runs from top surface 12 of temporary needle holder 10 to the bottom 26 of temporary needle holder 10. In this manner, boundary septum 22 provides a complete and effective boundary to prevent the passage of needles, or other sharps, from needle holder cushion layer 34 to lateral surface aperture 20. In the illustrated embodiment, the material from which top needle holder cushion layer 34 is formed comprises a non-coring resilient foam material. The non-coring quality of cushion layer 34 allows a needle to be inserted into top needle holder cushion layer 34 and withdrawn without leaving a noticeable hole. In this manner, a secondary implement can be reinserted into the same position without weakening or minimizing the ability of cushion layer 34 to retain the secondary implement, subsequent to the earlier insertion. Other materials of comparable functionality and characteristics may be employed.
As will be appreciated by those skilled in the art, a variety of types and configurations of temporary needle holder can be utilized without departing from the scope and spirit of the present invention. For example, in one embodiment the boundary septum extends only a portion of the length from the top surface of the needle holder cushion layer to the bottom of the needle holder cushion layer. In another embodiment a variety of types and configuration of cushion materials are be utilized. For example, in one embodiment, a thermalplastic rubber layer can be utilized. In another embodiment, another resilient polymer-based material can be utilized. In another embodiment, small layers of foam can be positioned adjacent one another in a manner to retain a needle or other sharp implement.
Figure 4 is a top view of the temporary needle holder 10 illustrating the juxtaposition of the side needle holder cushion layers 36, 38 relative to the instrument holder field 16. In the illustrated embodiment, side needle holder cushion layers 36, 38 are positioned on two sides of instrument holder field 16. Side needle holder cushion layers 36, 38 extend along the length of the outer boundary of the instrument holder field 16. As explained with reference to Figure 3, boundary septum 22 provides an effective barrier between top needle holder cushion layer 34 and side needle holder cushion layers 36 and 38. By virtue of the first and second side needle holder cushion layers 36, 38, a practitioner can insert more than one implement into a lateral surface aperture. This allows the placement of multiple syringes in the event that multiple syringes may need to be utilized during the course of the procedure or in the event that multiple heavy needle/syringe combinations or other implements are utilized. Figure 5 A is a top cross-sectional view of a temporary needle holder 10 according to one embodiment of the present invention. In the illustrated embodiment, the tips of needle syringe combinations 30a and 30b are inserted into side needle holder cushion layers 34 and 36, respectively. In the illustrated embodiment, it can be seen that the length of the needle syringe combinations 30a and 30b are sufficiently long that, in the absence of boundary septums 22a, 22b, the needles could extend from the side needle holder cushion layers 36, 38 and into the top needle holder cushion layer 34 and out of the associated instrument holder field 16 (see also Figure 5B).
Use of side needle holder cushion layers 36, 38 provides two additional points of placement for needles, trocars, or other sharp implements, in addition to the instrument holder field 16 (see Figure 1). Side needle holder cushion layers 36, 38 and their associated lateral apertures allow the practitioner to more easily keep track of particular needles, syringes, and associated medicinal fluids contained therein, to be utilized in subsequent portions of the procedure. Additionally, the needles 30a and 30b can rest on the support surface on which the temporary needle holder 10 is positioned. This minimizes potential breaking of the tips of the needles 30a, 30b while also minimizing tipping of the temporary needle holder 10. In the illustrated embodiment, boundary septum 22a extends along the entire length of temporary needle holder 10, such that the tip of needle syringe combination 30b is prevented from contacting the tip of needle syringe combination 30a in a manner that may cause damage, the exchange of fluids, or other contamination of needle syringe combination 30a from needle syringe combination 30b.
Figure 5B is a cross-sectional side view of a temporary needle holder 10 in which needle tips 40a and 40b have been inserted into a top needle holder cushion layer 34. In the illustrated embodiment, it can be seen that rim 24 of temporary needle holder 10 extends above the top surface of the instrument holder field 16. Needle tips 40a and 40b have been inserted into top needle holder cushion layer 34, such that the distal ends of the needle tips 40a and 40b extend a given amount into the top needle holder cushion layer. The length of needle tip 40a is substantially longer than that of needle tip 40b. It can be appreciated that, in the absence of a boundary septum 22 and in the event that needle tip 40a is inserted at an angle into top needle holder cushion layer 34, the point of needle tip 40a could extend out through the side needle holder cushion layer 36 and associated lateral surface aperture 20 (see Figure 1) in a manner that could result in inadvertent sticking or puncture of the practitioner who may be holding the temporary needle holder 10.
As will be appreciated by those skilled in the art, a variety of types and configurations of the temporary needle holder can be provided without departing from the scope and spirit of the present invention. For example, in one embodiment, the shape of the temporary needle holder is rectangular. In another embodiment, the shape of the temporary needle holder is other than a square or rectangle. In another embodiment, the sides of the needle holder cushion layers completely fill the inside of the temporary needle holder, such that the needle holder cushion layers are only bounded by the outside edges of the temporary needle holder and the boundary septa. Figure 6 A is a perspective view of an alternative embodiment of the present invention. In the illustrated embodiment, a first lateral surface aperture 20a and a second lateral surface aperture 20b are positioned in the side surface 14 of the temporary needle holder 10. In the illustrated embodiment, first lateral surface aperture 20a is positioned above second lateral surface aperture 20b. Second lateral surface aperture 20b is larger than first lateral surface aperture 20a. This allows larger needle syringe combinations to be placed in second lateral surface aperture 20b. As a result, a smaller needle syringe combination inserted into first lateral surface aperture 20a can rest directly on a larger needle syringe combination placed in second lateral surface aperture 20b. A plurality of lateral surface apertures can be provided in the same side surface of temporary needle holder 10, providing additional placement locations and potential sharps device organization by the practitioner during the course of the procedure.
Figure 6B is an illustrative view of a temporary needle holder 1OA, according to one embodiment of the present invention. In the illustrated embodiment, a instrument holder field 16a having two targets 18a is positioned in a top surface 12 of the temporary needle holder 1OA. A lateral surface aperture 20a having two targets 18b is positioned in a second side surface 14 of temporary needle holder 1OA. A second lateral surface aperture 20b having two targets 18c is positioned in a third side surface 15. In this manner, both primary and secondary surfaces on the temporary needle holder are provided with substantially identical instrument holder fields that can be utilized as desired by the practitioner. An arrangement as presently illustrated, in which the configuration of the instrument holder fields are substantially the same, while being provided at different locations on the temporary needle holder, can be desirable where a procedure requires the organization and/or reuse of many similar sharp implements. Alternatively, a plurality of sharp implements which simply require repeated use and safe disposition throughout the course of the procedure may be utilized. According to one embodiment of the present invention, all or substantially all of the surfaces of the temporary needle holder are provided with a instrument holder field, such that in the event that the temporary needle holder is tipped, a instrument holder field is readily available for the disposition of needles, trocars, or other sharp implements that need to be disposed of.
According to one embodiment of the present invention, the temporary needle holder 1OA is configured such that subsequent to the completion of the procedure, the entire temporary needle holder 1OA can be discarded without needing to remove the needles that have been inserted therein. In this manner, the temporary needle holder 1OA provides not only a safety mechanism for use during the course of the procedure, but also a quick, safe, and effective mechanism for disposing of the sharps subsequent to the completion of the procedure. Because lateral surface apertures 20a and 20b allow for the positioning of heavier needles, syringes, tools, or other implements, the temporary needle holder 1OA functions not only as a sharps receptacle for smaller needle tips or lighter syringes, but also as a depository for all potentially sharp implements that may need to be discarded subsequent to the completion of the procedure.
Figure 7 is a perspective view of a temporary instrument holder 110, according to another embodiment of the invention. In the illustrated embodiment, temporary instrument holder 110 has a lateral surface aperture 120, which is utilized to allow for insertion of medical instruments, such as needles, trocars, scalpels or other devices or implements, into the side of temporary instrument holder 110. Insertion of such medical instruments into the side of temporary instrument holder 110 helps to reduce tipping of temporary instrument holder 110. In the illustrated embodiment, temporary instrument holder 110 includes a body
1 1 1, a lid 113, a top surface 112, side surfaces 114, a instrument holder field 116, lateral surface aperture 120, a rim 124, a bottom 126, top instrument holder cushion layer 134, and lateral instrument holder cushion layer 133.
In one embodiment, body 111 of temporary instrument holder 110 provides a housing for instrument holder field 116. In the illustrated embodiment, body 111 comprises a generally box-like structure having side surfaces 114, rim 124 and bottom 126. Body 111 can be made of any suitable material, such as plastic or some other polymer. In the illustrated embodiment, lid 113 is linked to a side surface of body 111 via a hinge-type connection. Lid 113 is configured to enclose instrument holder field 116 when lid 1 13 is closed and positioned adjacent rim 124.
The outer boundary of lid 113 may be sized to correspond and mate with rim 124. Furthermore, lid 113 and body 111 may include a latching device to substantially secure lid 113 to body 111.
In one embodiment, lid 113 is configured and sized such that its depth is sufficient to allow needle tips 140a and 140b to be positioned in instrument holder field 116 with lid 113 closed without having the needle tips 140a and 140b interfere with the complete closure of lid 113. In this manner, after a practitioner has disposed of various medical instruments, such as needle tips, the practitioner may close lid 113. Closing lid 113 encloses the needle tips in instrument holder field 116 to in turn reduce the risk of accidental puncture of the practitioner by the disposed medical devices. When lid 113 is closed, lid 113 may effectively serve as a boundary septum for lateral surface aperture 120. In some other embodiments, lid 113 may include additional instrument holding fields.
Top surface 112 of temporary instrument holder 110 includes instrument holder field 116. Top surface 112 of temporary instrument holder 110 is configured such that it is facing upward allowing it to be easily viewed and accessed by a practitioner when lid 113 is open. A plurality of targets 118 are positioned in instrument holder field 116 to provide a visual identification of the potential placement areas for medical instruments, such as needles, trocars, scalpels or other sharp implements or tools that may be utilized during the course of a procedure. A practitioner can insert smaller and/or lighter needle apparatus, such as needle tips, emptied syringes, or an TV trocar into top surface 112.
Lateral surface aperture 120 is positioned in side surface 114 of temporary instrument holder 110 in a manner that the practitioner can insert larger and/or heavier medical instruments such as a scalpel, a needle syringe combination, or some other sharp implement, into lateral surface aperture 120. Lateral surface aperture 120 provides not only a supplementary instrument holder field for insertion of sharp devices, but is also positioned closer to the surgical surface, allowing for resting of the medical instrument on the surgical surface and thereby minimizing tipping of temporary instrument holder 110. Lateral surface aperture 120 is one example of a feature enabling insertion of a needle or other sharp device into a second side of the temporary instrument holder.
In the illustrated embodiment, lateral surface aperture 120 is rectangular in shape. The shape and configuration of lateral surface aperture 120 enables a variety of types, shapes and sizes of implements to be inserted therein. The size and configuration of lateral surface aperture 120 may be adjusted to accommodate for the size and configuration of various medical implements. For example, in the illustrated embodiment, a scalpel 131 has been inserted in lateral surface aperture 120. The positioning of scalpel 131 in lateral surface aperture 120 facilitates the contact of scalpel 131 with a support surface. By contacting the support surface, scalpel 131 helps to reduce tipping of temporary instrument holder 110. Tn this manner, desired and intended positioning of temporary instrument holder 110 is maintained. Moreover, a practitioner is thus able to quickly identify instrument holder field 116 for the insertion of additional medical instruments such as needles, sharps or other tools or implements, while also being able to quickly identify the positioning of lateral surface aperture 120 and scalpel 131 positioned therein.
Rim 124 is positioned to provide an outer boundary for instrument holder field 116. Rim 124 creates a slight recess between top surface 112 of temporary instrument holder 110 and the elevation of instrument holder field 116. In this manner, rim 124 prevents inadvertent slipping of sharp medical instruments from top surface 112 of instrument holder field 116 to the exterior of temporary instrument holder 110. Thus, a practitioner can safely grasp temporary instrument holder 110 and insert a needle or other medical instrument into instrument holder field 116. In the event that the needle or some other medical instrument slips or does not entirely puncture instrument holder field 116, the tip of the medical instrument will typically be caught by rim 124. This catching generally prevents additional slipping and puncturing of the practitioner.
Bottom 126 is positioned on the side of temporary instrument holder 110 opposite top surface 112. Bottom 126 is configured to be positioned on a surgical or other medical work surface on which temporary instrument holder 110 is to be utilized. In one embodiment, bottom 126 includes a non-slip surface or adhesive surface which facilitates retention of temporary instrument holder 110 on the surgical surface and additionally prevents tipping of temporary instrument holder 1 10.
In the illustrated embodiment, lateral instrument holder cushion layer 133 extends a depth into temporary instrument holder 110. The size of the lateral instrument cushion layer 133 may correspond with, and even extend beyond, the location of lateral surface needle aperture 120. In this embodiment, lateral instrument holder cushion layer 133 substantially fills the volume of body 111 below rim 124. In this manner, needles or scalpels or other sharp implements which are inserted into instrument holder field 116 and/or lateral surface aperture 120 are inserted into instrument holder cushion layer 133.
In the illustrated embodiment, the material from which lateral instrument holder cushion layer 133 is formed comprises a non-coring resilient foam material. The non-coring quality of instrument holder cushion layer 133 allows a needle to be inserted into instrument holder cushion layer 133 and withdrawn without leaving a noticeable hole. Thus, another implement can be subsequently inserted into the same position in instrument holder cushion layer 133 without weakening or minimizing the ability of instrument holder cushion layer 133 to retain that implement.
As will be appreciated by those skilled in the art, a variety of types and configurations of temporary instrument holders can be utilized without departing from the scope and spirit of the present invention. Tn one embodiment, a variety of types and configurations of cushion materials may be utilized. For example, in one embodiment, a thermoplastic rubber layer can be utilized. In another embodiment, another resilient polymer-based material can be utilized. In another embodiment, small layers of foam can be positioned adjacent one another in a manner to retain a needle or other sharp implement.
Figure 8 illustrates an alternative embodiment of temporary instrument holder 110. In this embodiment, a first lateral surface aperture 120a and a second lateral surface aperture 120b are positioned in side surface 114 of the temporary instrument holder 110. In the illustrated embodiment, first lateral surface aperture
120a is positioned to the side of second lateral surface aperture 120b. First lateral surface aperture 120a is larger and a different shape than second lateral surface aperture 120b; first lateral surface aperture 120a is rectangular and second lateral surface aperture 120b is circular. This enables different types and sizes of medical implements to be placed in either the first or second lateral surface apertures 120a and 120b, respectively. For example, an implement, such as a scalpel, may be inserted into first lateral surface aperture 120a and a needle combination may be placed in second lateral surface aperture 120b. A plurality of lateral surface apertures may be provided in the same side surface of temporary instrument holder 110, providing additional placement locations and potential sharps device organization by the practitioner during the course of the procedure.
Further illustrated in Figure 8 is a boundary septum 122 separating lateral surface apertures 120a and 120b from instrument holder field 116. In one embodiment, boundary septum 122 runs from top surface 112 of temporary instrument holder 110 to bottom 126 of temporary instrument holder 110, and extends from one side of body 111 to the opposing side of body 111. In this manner, boundary septum 122 may provide a complete and effective boundary to prevent the passage of sharps from instrument holder cushion layer 134 to lateral surface apertures 120a and 120b.
In the illustrated embodiment, instrument holder field 116 comprises a top instrument holder cushion layer 134. In this embodiment, top instrument holder cushion layer 134 is rectangular shaped to correspond to a portion of body 111 defined by three side surfaces of body 111, bottom 126 and boundary septum 122. Lateral surface apertures 120a and 120b comprise a side instrument holder cushion layer 138. In the illustrated embodiment, side instrument holder cushion layer 138 substantially fills the volume of body 111 defined by three side surfaces 114, bottom 126 and boundary septums 122.
As will be appreciated by those skilled in the art, a variety of types and configurations of temporary instrument holders may be utilized without departing from the scope and spirit of the present invention. For example, in one embodiment the boundary septum extends only a portion of the length from the top surface of the instrument holder cushion layer to the bottom of the instrument holder cushion layer.
Figure 9 is an illustrative view of a temporary instrument holder 110, according to one embodiment of the invention. In the illustrated embodiment, body 111 of temporary instrument holder 110 comprises first and second instrument holder fields 116a and 116b positioned in top surface 112 of temporary instrument holder 110 and first and second lateral surface apertures 120a and 120b positioned in opposing side surfaces 114 of temporary instrument holder 1 10. Tn this embodiment, each of first and second instrument holder fields 1 16a and 116b are positioned proximate opposing corners of body 111. Likewise, each of first and second lateral surface apertures 120a and 120b may be positioned in opposing corners of body 111.
A first boundary septum 122a separates first lateral surface aperture 120a from- first instrument holder field 116a, second instrument holder field 116b and second lateral surface aperture 120b. In one embodiment, first boundary septum 122a runs from top surface 112 of temporary instrument holder 110 to bottom 126 of temporary instrument holder 110. In this manner, first boundary septum 122a may provide a complete and effective boundary to prevent the passage of scalpels, needles, sharps, or other implements between first lateral surface aperture 120a and first and second instrument holder fields 116a and 116b and second lateral surface aperture 120b.
A second boundary septum 122b separates second lateral surface aperture 120b from first instrument holder field 116a, second instrument holder field 116b and first lateral surface aperture 120a. In one embodiment, second boundary septum 122b runs from top surface 1 12 of temporary instrument holder 110 to bottom 126 of temporary instrument holder 110. In this manner, second boundary septum 122b may provide a complete and effective boundary to prevent the passage of scalpels, needles, sharps, or other implements between second lateral surface aperture 120b and first and second instrument holder fields 116a and 116b and first lateral surface aperture 120a. In this embodiment, four separate cushion layers are provided — one for each of the first and second instrument holder fields
116a and 116b and one each for the first and second lateral surface apertures 120a and 120b.
Further included in the embodiment of Figure 9 are a third lateral surface aperture 120c and associated third boundary septum 122c, and a fourth lateral surface aperture 12Od and associated fourth boundary septum 122d in lid 113. In the illustrated embodiment, third boundary septum 122c may provide a complete boundary to prevent the passage of sharps such as scalpels, needles, or other implements from third lateral surface aperture 120c. Likewise, fourth boundary septum 122d may provide a complete boundary to prevent the passage of scalpels, needles, sharps, or other implements from fourth lateral surface aperture 12Od. The positioning of third and fourth lateral surface apertures 120c and 12Od in lid 113 provides additional locations for a practitioner to place medical implements while not in use. Furthermore, positioning of third and fourth lateral surface apertures 120c and 120d in lid 113 enables a practitioner to effectively utilize the space of temporary instrument holder 110. An arrangement as presently disclosed may be desirable where a procedure requires the organization and/or reuse of many similar sharp implements. Alternatively, a plurality of sharp implements which simply require repeated use and safe disposition throughout the course of the procedure may be utilized. According to one embodiment of the present invention, all or substantially all of the surfaces of the temporary instrument holder are provided with a instrument holder field, such that in the event that the temporary instrument holder is tipped, a instrument holder field is readily available for the disposition of needles, trocars, or other sharp implements that need to be disposed.
According to some embodiments of the present invention, subsequent to the completion of the procedure, the entire temporary instrument holder 110 may be discarded as a unit, including any used instruments inserted into temporary instrument holder 110. This allows the disposal of contaminated instruments without necessitating the removal of needles and/or instruments that have been inserted into the temporary instrument holder 1 10. Thus, temporary instrument holder 110 provides not only a safety mechanism for use during the course of the procedure, but also a quick, safe, and effective mechanism for disposing of the sharps subsequent to the completion of the procedure. Because lateral surface apertures allow for the positioning of heavier needles, syringes, tools, or other implements, temporary instrument holder 110 functions not only as a sharps receptacle for smaller needle tips or lighter syringes, but also as a depository for all potentially sharp implements that may need to be discarded subsequent to the completion of the procedure.
As will be appreciated by those of skill in the art, a variety of types and configurations of temporary instrument holders can be provided without departing from the scope and spirit of the present invention. For example, in one example embodiment, a different number and configuration of targets are provided in the instrument holder field. In another example embodiment, the lateral surface aperture is of a different size, shape and/or configuration. In another example embodiment, the lid is sized and configured so as to enclose both instrument holder field and lateral surface aperture.
With attention now to Figures 1OA and 1OB, various elements of a sharps holder apparatus, according to one example embodiment of the present invention, are disclosed. In the illustrated embodiment, the sharps holder apparatus 200 comprises a housing 201, a top surface cushion layer 226, and a side-surface cushion layer 228. Top surface cushion layer 226 and side surface cushion layer
228 can be positioned within housing 201 to provide a mechanism for capturing sharps such as needles, syringes, trocars, scalpels or other sharp medical implements that may be utilized within the surgical field. Housing 201 may provide a mechanism for accommodating and securing top surface cushion layer 226 and side surface cushion layer 228 in a manner that allows for securement of the sharps by cushion layers 226 and 228.
In the illustrated embodiment, housing 201 may include an outer wall 202, a first cavity 204, a second cavity 206, a boundary septum 207, a top surface aperture 208, a side surface aperture 210, and a moveable bottom member 215. Outer wall 202 can define the outer boundary of housing 201 and provides a secure framework in which top surface cushion layer 226 and side surface cushion layer 228 can be positioned. Outer wall 202 partially defines a first cavity 204 and a second cavity 206. First cavity 204 may have a substantially square configuration having a depth configured to accommodate top surface cushion layer 226. Second cavity 206 may have a depth and size to accommodate second side surface cushion layer 228. Boundary septum 207 can separate first cavity 204 from second cavity 206. Utilizing a boundary septum 207 prevents passage of a trocar, needle, or other sharp implement between top surface cushion layer 226 and side surface cushion layer 228.
As illustrated, housing 201 may include a top surface aperture 208 and side surface aperture 210. Top surface aperture 208 is defined by the top surface of housing 201. Side surface aperture 210 may be positioned on the side surface of housing 201. When sharps holder apparatus 200 is MIy assembled and resting on the surgical surface, top surface aperture 208 may then be positioned upward allowing needles, trocars, or other instruments to be inserted therein, as illustrated in Fig. HB. As shown in Fig. 1OA, side surface aperture 210 may be positioned on the side of the needle holder apparatus in a manner such that heavier or larger implements, such as a fluid-filled syringe 242 (Fig. HB), a scalpel 256 (Fig. 12), or other implement can be positioned in the side surface cushion layer 228 while the instrument, trocar, or other apparatus can rest on the table or other surgical surface in manner to prevent tipping of the needle holder apparatus.
A top rim contact surface 212, top barrier surface 214, and side rim contact surfaces 250 are also illustrated. Top rim contact surface 212, top barrier surface 214, and side rim contact surface 250 facilitates proper positioning and securement of top surface cushion layer 226 and side surface cushion layer 228 during assembly. For example, when top surface cushion layer 226 is positioned in first cavity 204, top surface cushion layer 226 may be slid into first cavity 204 until the outer rim of the upper surface of top surface cushion layer 226 contacts rim contact surface 212. Contact surface 212 can stop additional upward movement of top surface cushion layer 226, and also provides indication to the user that further advancement of the top surface cushion layer is no longer necessary.
Top barrier surface 214 may provide a solid contact surface that also stops further advancement of side surface cushion layer 228 when side surface cushion layer 228 is being inserted into housing 201. Side rim contact surfaces 250 may maintain the lateral positioning of side surface cushion layer 228 in second cavity 206. In this manner, side surface cushion layer may be prevented from migrating out of side surface aperture 210 during assembly or usage of the needle holder apparatus.
A moveable bottom member 215 is also illustrated. Moveable bottom member 215 may be configured to be secured to the bottom periphery of outer wall 202 to secure top surface cushion layer 226 and side surface cushion layer 228 within their respective cavities 204 and 206. As illustrated, moveable bottom member 215 may be attached to one side of outer wall 202 using a hinge 217. In this manner, the desired positioning of moveable bottom member 215 relative to the other portions of housing 201 may be maintained until the top surface cushion layer 226 and side surface cushion layer 228 have been positioned within first cavity 204 and second cavity 206.
Once top surface cushion layer 226 and side surface cushion layer 228 have been positioned within housing 201, the user can simply hinge moveable bottom member 215 into cooperative and locked engagement with the entire bottom periphery of outer wall 202. As illustrated, outer wall 202 includes a snap fit ridge
220 and moveable bottom member 215 includes a snap fit flange 222. When moveable bottom member 215 is hinged to a closed position relative to outer wall 202, snap fit flange 222 biases over snap fit ridge 220 securing moveable bottom member 215 in position relative to the other components of housing 201. In this manner, top surface cushion layer 226 and side surface cushion layer 228 can be secured within housing 201 in a relatively simple, effective, and cost effective manner.
As illustrated, side margin supports 216 and bottom margin supports 218 may be provided. Side margin supports 216 comprise a raised ridge, and bottom margin supports 218 comprise raised panels. Side margin supports 216 and bottom margin supports 218 may be adapted to contact portions of top surface cushion layer 226 and side surface cushion layer 228. Side margin supports 216 and bottom margin supports 218 may effectively secure top surface cushion layers 226 and side surface cushion layer 228 within first cavity and second cavity 204 and 206, even when there is a slight margin left by a discrepancy between the size of top surface cushion layer 226 and first cavity 204 or side surface cushion layer 228 and second cavity 206. In this manner, any gap that is left by a slightly smaller side of cushion layers 226 and 228 may be effectively filled, while allowing for larger cushion layers to also be inserted within first cavity 204 and second cavity 206.
As illustrated, side margin supports 216 may be positioned on the inside of first cavity 204 and second cavity 206. For example, side margin supports 216 can be provided on each of the four lateral surfaces along outer wall 202 and boundary septum 207. The somewhat narrow and stiffened nature of side margin supports 216 and bottom margin supports 218 may allow for a certain amount of deformation of cushion layers 226 and 228 in the event that there is little or no margin between the sides of the cushion layer and the respective cavity in which it is being positioned. Additionally, the ridged nature of side margin supports 216 and bottom margin supports 218 may allow for securement of the cushion layer in the event that there is a somewhat larger margin between the sides of the cushion layer and the respective cavity in which it is positioned. Side margin supports 216 may be configured to fill lateral discrepancies in size between the cushion layer 226, 228, and the cavities 204 and 206, respectively. Bottom margin supports 218 may be configured to facilitate contact between top rim contact surface 212 and the top surface cushion layer 226. Similarly, bottom margin support 218 may facilitate contact between top barrier surface 214 and the side surface cushion layer 228.
As illustrated, an adhesive cover strip 224 may extend from the underside of moveable bottom member 215. Adhesive cover strip 224 includes a tab that can be grasped by a user facilitating removal of adhesive cover strip 224 from the respective adhesive strip. When positioned on the underside of moveable bottom member 215, adhesive cover strip 224 may secure sharps holder apparatus 200 on a surgical or other support surface, minimizing tipping or inadvertent movement of the apparatus during a surgical procedure being performed.
Top surface cushion layer 226 and side surface cushion layer 228 are depicted in Figure 1OB. As illustrated, top surface cushion layer 226 may include a side surface 230 and a top surface 232. As previously discussed, side surface 230 may be positioned in contact with outer wall 202 and boundary septum 207. Top surface 232 may be largely exposed to the external working environment by top surface aperture 208 of housing 201. In this manner, top surface 232 can be accessed by a user for positioning needles, trocars, scalpels, or the like within the sharps holder apparatus. The outer periphery of top surface 232 may be configured to contact top rim contact surface 212 to secure the positioning of top surface cushion layer 226 within housing 201. Top surface cushion layer 226 also includes a bottom surface 238. Bottom surface 238 may be configured to be in contact with moveable bottom member 215 so that top surface cushion layer 226 is thereby cooperatively secured between top rim contact surface 212 and bottom surface 238. In the illustrated embodiment, a plurality of targets 233 of top surface cushion layer 226 are depicted. Targets 233 are positioned on top surface 232 of top surface cushion layer 226. Targets 233 may provide a visual identification facilitating proper insertion of needles, trocars, or other instruments within the top surface cushion layer 226. As illustrated, a side surface cushion layer 228 is also depicted. Side surface cushion layer 228 includes a side surface 234, a top surface 236, and bottom surface 240. As previously discussed, top surface 236 may be configured to be in contact with a top barrier surface 214. One of side surfaces 234 may be exposed to the external environment by side surface aperture 210. In this manner, a practitioner, such as a surgeon or nurse for example, can insert a scalpel, fluid filled syringe, or other instrument into side surface cushion layer 228. In this manner, when moveable bottom member 215 is resting on the support surface, the instrument positioned within side surface cushion layer 228 can rest on the surgical surface in a manner to prevent tipping of the needle holder apparatus or inadvertent breakage of the instrument positioned within side surface cushion layer 228.
Bottom surface 240 may be positioned in contact with moveable bottom member 215. In this manner, side surface cushion layer 228 may be sandwiched between top barrier surface 214 and moveable bottom member 2Ϊ5.
As will be appreciated by those skilled in the art, a variety of types and configurations of the sharps holder apparatus can be implemented without departing from the scope and spirit of the present invention. For example, according to one embodiment of the present invention, a single needle cushion layer may be provided. In another embodiment, the moveable bottom member may be locked into place once the sharps holder apparatus has been fully assembled. In another embodiment, moveable bottom member may be secured to the needle holder apparatus using other than a hinge. In another embodiment, the moveable bottom member may not be secured to the needle holder apparatus but positioned in place once the one or more cushion layers have been positioned within the housing. In yet another embodiment the moveable bottom member may comprise a plurality of components, which cooperatively secure one or more cushion layers within the housing. In yet another embodiment, one or more side ports may be provided in addition to a top surface cushion layer.
Figure 1 IA is a top perspective view of sharps holder apparatus 200 during assembly. In the illustrated embodiment, top surface cushion layer 226 may be positioned within housing 201. As previously discussed with reference to Figures 1OA and 1OB, top surface cushion layer 226 may be configured to be positioned within first cavity 204 (see Figure 1OA and 10B). As illustrated, top surface cushion layer 226 may be fully advanced within housing 201 such that top surface cushion layer 226 is accessible through top surface aperture 208. A plurality of targets 233 may be seen through top surface aperture 208. In this manner, potentially desired points of contact between the needle and the top surface cushion layer 226 are clearly displayed to the user. A top rim 252 is also illustrated. Top rim 252 may be positioned on the upward facing side of the top rim contact surface 212 depicted in Figure 1OA. Top rim 252 may have a desired amount of elevation over and above top surface 232 of top surface cushion layer 226. As illustrated, side surface cushion layer 228 may be fully advanced within second cavity 206 (see Figure 1OA and 10B). Side surface cushion layer 228 may be in contact with top barrier surface 214. Additionally, a side rim 254 may be in contact with a side surface 234 of side surface cushion layer 228. In this manner, inadvertent migration of side surface cushion layer 228 out through side surface aperture 210 may be prevented. Side surface aperture 210 may provide access to side surface cushion layer 228. In this manner, a practitioner can insert needles, syringes, scalpels, or other medical devices into the side of the sharps holder apparatus 200. In this manner, heavier items, such as a fluid-filled syringe, scalpel, or other instrument can rest on the table to prevent inadvertent breakage or damage to the medical instrument which is inserted into side surface cushion layer 228. In the depicted embodiment, the movable bottom member 215 is partially closed in relation to the other components of housing 201. As previously discussed, movable bottom member 215 may be secured to housing 201 utilizing a hinge 217. Snap fit flange 222 on the outer periphery on a portion of movable bottom member 215 may allow for securement of the movable bottom member 215 to snap fit ridge 220 of housing 201 (see Figure 1OA and 10B). In this manner, when movable bottom member 215 is closed, the fit between snap fit ridge 220 and snap fit flange 222 may effectively secure movable bottom member 215 to the other components of the housing, thereby securing the position of top surface cushion layer 226 and side surface cushion layer 228. A bottom margin support member 218 is also shown. The illustrated bottom margin support 218 may be configured to contact side surface cushion layer 228 to ensure a desired fit between side surface cushion layer, top barrier surface 214, and movable bottom member 215.
Figure HB illustrates sharps holder apparatus 200 during use. In the illustrated embodiment, the movable bottom member 215 may be secured to the other components of housing 201. In this manner, top surface cushion layer 226 and side surface cushion layer 228 may be secured within housing 201 to allow for desired operation of the sharps holder apparatus.
A needle syringe combination 242 is depicted as being inserted into side surface cushion layer 228. The needle syringe combination may include an amount of fluid which adds substantially to the weight of needle syringe combination 242. In the event that needle syringe combination 242 were inserted into top surface cushion layer 226, the weight of needle syringe combination 242 could tip the sharps holder apparatus 200 or inadvertently result in breakage of the needle portion of the needle syringe combination 242. In the illustrated embodiment, needle syringe combination 242 can rest on the surgical surface on which the needle holder apparatus is positioned. In this manner, positioning of the needle syringe combination 242 is maintained until the needle syringe combination needs to be utilized again or until the entire needle holder apparatus, including the needle syringe combination 242, is disposed. As illustrated, needle tips 244a and 244b may be positioned within the top surface cushion layer 226. In the illustrated embodiment, a first needle tip 244a may be positioned within a first target 233 and a second needle tip 244b also positioned within a different target 233. In this manner, the practitioner can quickly identify potential open areas where needle tip or other sharp implement can be inserted. Additionally, the practitioner can quickly identify the amount of remaining space for sharps that are used in connection with subsequent portions of the procedure.
The top barrier surface 214 may be provided to prevent inadvertent insertion of a needle or other sharp implement into the top surface 236 (not shown) of side surface cushion layer 228. In this manner, inadvertent migration of a needle tip through top surface 236 of side surface cushion layer 228 and out through side surface aperture 210 may be prevented.
Figure 12 is a perspective view of sharps holder apparatus 200 according to another illustrative embodiment of the present invention. In the illustrated embodiment, first and second side surface cushion layers 228a and 228b are illustrated. By providing first and second side surface cushion layers 228a and 228b, a plurality of different medical instruments may be inserted into the sharps holder apparatus 200 organized in an efficient manner. For example, as illustrated, a needle syringe combination 242 may be inserted into side surface cushion layer 228a. Scalpel 256 may also be positioned in side surface cushion layer 228b. In this manner, interference or inadvertent breakage by contact between needle syringe combination 242 and scalpel 256 may be prevented. According to one embodiment of the present invention, side surface cushion layers 228a and 228b may comprise a single internal piece of foam which may be simply separated by a single septum member (not shown) in the outer wall of housing 201. In other words, first and second lateral surface apertures may be provided to access a single side surface to cushion layer positioned on the interior of housing 20] .
As illustrated, a lid 256 may be provided. Lid 256 may be configured to be positioned over sharps holder apparatus 200 subsequent to usage of the sharps holder apparatus 200 and in preparation for disposal of the apparatus and the needles, syringes, or other medical implements utilized therewith. As illustrated, lid 258 may include a top surface 260, a sidewall 262, and an expandable drape 264. Top surface 260 may comprise a hardened material which minimizes inadvertent puncture by implements that are positioned within sharps holder apparatus 200. Sidewall 262 may provide an amount of displacement between the upper surface of the top surface cushion layer 226 and top surface 260.
Expandable drape 264 may be deployed subsequent to closing of lid 258. Expandable drape 264 may be made of a material that allows expandable drape 264 to extend past and enclose components positioned in side surface cushion layers 228a and 228b. Similarly, expandable drape 264 may include several pleats that allow expansion in a similar manner. Alternatively, the expandable drape 264 may not entirely enclose the components positioned within side cushion layer 228 that are utilized to secure those components in place during disposal of the needle holder apparatus, but may expand to contact any components positioned within side cushion layer 228 and provide additional stability to the components.
As will be appreciated by those skilled in the art, a variety of types and configurations of sharps holder apparatus can be utilized without departing from the scope and spirit of the present invention. According to one embodiment of the present invention, the lid 258 may include an extension portion which secures part or all of the apparatus positioned within the side surface cushion layers. In another embodiment, needle holder apparatus may include only side ports and does not include a top surface for inserting needles, trocars, syringes, or the like. In yet another embodiment, the side surface cushion layers may include targets facilitating the insertion of instruments into a central or desired location within the side surface cushion layers. The foregoing, and other, aspects of the present invention will become more fully apparent from the following description and appended claims. The disclosed embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description.
