Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This patent application claims the benefit of priority to U.S. Provisional Patent Application No. 61/360,975, filed Jul. 2, 2010. The aforementioned patent application is incorporated by reference herein in its entirety.

BACKGROUND

1. Field of the Disclosure
The present disclosure relates to methods and systems for sterilizing surgical instruments and related equipment. Particularly, the present disclosure is directed to improved systems and methods for sterilization by sequestering count sheets in locations that are easily accessible to hospital personnel.
2. Description of Related Art
Open top surgical trays are conventionally wrapped in a sterilization wrap which is generally a non-woven fabric (but can be a woven textile fabric) with surgical instruments inside to form what is typically referred to as a sterilization pack. By way of further example, a rigid sterilization container with a lid may also be used, sometimes referred to as a container. Such containers are generally rigid and are not wrapped The sterilant penetrates the container through a filter on the lid, and this filter also serves as a sterile barrier. Once a sterilization pack or container has completed a sterilization cycle, it may be removed from the sterilizer and stored for future use during surgery.
Surgical instrument trays and containers are generally sterilized using steam or another gas. This gas is commonly referred to as the sterilant. The contents of the tray or container, such as surgical instruments, are sterilized by way of the sterilant gas contacting and sterilizing the instruments. Sterilization of surgical tools including scalpels, scissors and clamps may be thus accomplished in a known manner by placing the tools in a sterilization tray (or container), wrapping the tray with a sterilization wrap to form a sterilization pack and then placing the pack or container into a sterilizer.
Persons have recognized that count sheets can cause problems in sterilization. Count sheets, sometimes referred to as inventory sheets, surgical instrument count sheets and the like, are sheets of paper (such as 8.5×11 inch sheets of paper) that are printed out in hospital sterilization departments that list the contents of each wrapped sterilization tray or container.
Count sheets sometimes accompany instruments in the sterilization tray or container. While these sheets are sterilized with the surgical instruments in the tray under such circumstances, ink and other chemical contaminants from the count sheet can be deposited on the contents of the tray, including surgical instruments. In addition, paper material from the count sheet can also be deposited on the instruments. Either of these conditions is in contravention to certain aspects of the AAMI standards and the AORN Recommended Practices, which are incorporated herein by reference in their entireties. This can result in toxic chemical contamination or other contamination, possibly endangering the health and safety of the patient. While those of skill in the art can attempt to remedy this situation by placing the count sheet in packaging such as a paper bag, peel pack or the like within the sterilization pack or container, this still requires the package to be opened to confirm the contents of the container, which simultaneously compromises the sterility of the instruments, possibly requiring re-sterilization.
It has also been standard practice to attempt to attach count sheets to the exterior of sterilization containers and wrapped sterilization packs. With respect to containers, some have stapled the count sheet itself around a handle of the container and run both through a sterilization cycle. This can unduly damage the count sheet, to say nothing of possibly introducing one or more staples into the OR that may not be noticed and accounted for. Similarly, some have tried to tape the count sheet directly to the sterilization wrap. This can damage the count sheet, but removal of the tape from the wrap can tear the wrap, compromising sterility of the sterilization pack, thereby requiring re-sterilization. Some have attempted to tape count sheets to sterilization wraps inside of paper bags, but this presents the same problem with tearing the wrap, and presents the additional disadvantage of not being able to view the count sheet in any respect without tearing the bag and removing the count sheet from the bag.
Some have tried to place count sheets in what are commonly referred to as “peel packs”, which include a transparent plastic film on a breathable paper backing. The peel pack is then attached typically to the wrap of a sterilization pack with tape. However, this can lead to a number of problems. First, it should be noted that the peel pack is typically placed with the transparent side up, thereby possibly preventing sterilant from infiltrating the peel pack, thereby possibly preventing sterilization of the count sheet. This can lead to a sense of false security of sterility of the count sheet. If the peel pack is later opened in the sterile field of the Operating Room (“OR”), the sterile field is compromised, thereby jeopardizing the procedure, the patient, and/or generally resulting in delaying the procedure until the sterile field can be reestablished, which typically requires all instruments in the tray to be re-sterilized. Use of the peel pack is also inconvenience because it requires tape to be peeled off of the wrap of the sterilization pack, which can tear a hole in the wrap, and compromise the sterility of the pack once sterilized.
As will be appreciated from the above discussion, the approaches present in the art are inadequate for a variety of reasons. The present disclosure provides a solution for these problems.

DETAILED DESCRIPTION

Reference will now be made in detail to the present preferred embodiments of the disclosure, examples of which are illustrated in the accompanying drawings. The methods and corresponding steps of the disclosed embodiments will be described in conjunction with the detailed description of the systems.
The deficiencies in the art are set forth above. Applicants have invented new ways of addressing these problems, as embodied herein. In one aspect, the disclosure provides methods of providing a count sheet, securing the count sheet in a protective count sheet holder that defines an enclosure, and securing the count sheet holder to a wrapped sterilization tray or instrument container, and sterilizing tray or container. The enclosure is adapted and configured to protect the count sheet, but the count sheet is easily removable post-sterilization, thus decreasing the chances that the sterility of the wrapped tray or the container will be compromised. Thus, the sterility of the package is maintained while permitting access to the count sheet after sterilization, yet the sterility of the surgical instruments or other tray/container contents is not compromised. The enclosure is preferably sufficiently durable to survive the sterilization process, and should be able to protect and contain the count sheet during sterilization, and during the trip from the sterilization department of the hospital to the operating room (“O.R.”). Preferably, the enclosure includes a variety of indicia including, for example, instructions for use and an indication that the contents of the enclosure are not sterile. This can be implemented in a variety of ways.
In accordance with one embodiment, a count sheet holder including an enclosure is provided for a count sheet that can be used with a wrapped sterilization tray or a container. For purposes of illustration, and not limitation, an exemplary count sheet holder 100 is illustrated in FIGS. 1-3. As illustrated in FIG. 1(A), count sheet holder 100 is provided in the form of a pouch formed from a first layer 110 of material disposed on a base, or second layer of material 120. If desired, the second layer 120 of material can include adhesive on its back side 122 that may be exposed by removing a further protective layer 130. As illustrated, first layer 110 and second layer 120 are joined about three of four sides in a bonding region 114 by various means (e.g., heat sealing, adhesive, solvent welding, ultrasound welding, etc.) and defining a generally rectangular compartment 118 therein and leaving an elongate opening 112 along one edge to permit a count sheet 170 to be inserted into the compartment 118 of the count sheet holder 100. Indicia 116 of various types may be provided to facilitate proper use of the enclosure 100. Preferably, indicia 117 of non-sterility of the count sheet is also provided to inform hospital personnel that the count sheet is not to be considered to be sterile, thereby minimizing the chances that the sterile field in the OR will be compromised by the count sheet. If desired, a foldable flap (shown in dashed lines as 143 with an adhesive patch 144) can be provided to fold over opening 112 after the count sheet is inserted. By way of another example, a zipper closure(not shown) can be provided along opening 112 to maintain count sheet holder 100 in a closed condition.
As further illustrated in FIG. 1(B), an alternative count sheet holder 100′ is provided in the form of a pouch formed from a first layer 110′ of material disposed on a base, or second layer of material 120′. If desired, the second layer 120′ of material can include adhesive on its back side 122′ that may be exposed by removing a further protective layer 130′. As illustrated, first layer 110′ and second layer 120′ are joined about three of four sides in a bonding region 114′ by various means (e.g., heat sealing, adhesive, solvent welding, ultrasound welding, etc.) and defining a generally rectangular compartment 118′ therein and leaving an elongate opening 112′ along one edge to permit a count sheet 170′ to be inserted into the compartment 118′ of the count sheet holder 100′ along the direction of arrow “A”. Indicia 116′ of various types may be provided to facilitate proper use of the enclosure 100′. As illustrated, an overhang 145 of the top layer 110′ is provided to protect the edge of the count sheet 170′, and to facilitate the easy removal of the count sheet from the holder 100′. If desired, the overhang 145 can include adhesive disposed on an inner face 145 a of the overhang, and may be covered with a removable covering 145 b that can be removed to expose the adhesive, such that the adhesive, when exposed, causes the overhang adhere to the sterilization wrap when pressed against the wrap after the count sheet is inserted in the count sheet holder, thereby preventing access to the count sheet. Preferably, the count sheet holder then further includes a removable tamper evident strip 179 that, when removed, provides access to the count sheet and visual indication that the count sheet holder has been compromised. Alternatively, strip 179 can be a zipper closure that can permit selective opening and closing of the count sheet holder. In one embodiment, the count sheet holder can include material that permits writing thereon. The count sheet holder can use an adhesive such as a acrylic copolymer to attach it to a wrapped tray or a sterilization container.
After the adhesive is exposed, the count sheet holder 100 may be attached to the sterilization wrap of a package as illustrated in FIG. 2 or directly to the body of a sterilization container as illustrated in FIG. 3. As illustrated in FIG. 2, a sterilization tray is depicted wrapped in a KimGuard® type sterilization wrap, wherein a corner 152 of the wrap 150 is wrapped and tucked underneath the package. While not preferred, enclosure could be provided with an elongate member, cord, or tape 119 that can be wrapped into the sterilization wrap to secure the enclosure to the package, but still leaving the body of the count sheet holder exposed and visible.
By way of further example, in contrast to a wrapped set, a container 160 is illustrated in FIG. 3 having a bottom portion 162 for receiving a plurality of instruments and a removable cover portion 164 for maintaining closure of the container. While not preferred, an adhesive backed count sheet holder 100 can be used in connection with a container as illustrated in FIG. 3, but preferably a count sheet holder similar to embodiment 200 is used, described in detail below.
Count sheet holder 100, 100′ can be made in a variety of ways and from a variety of materials. Preferably, count sheet holder 100 is made from a highly durable material that can withstand the conditions of sterilization (e.g., high humidity and 275° F. for about twenty minutes, with a total cycle time of about an hour including heat up and cool down), and handling from the sterilization department of a hospital to the O.R. For example, count sheet holder 100 can be made from layers of polypropylene (“PP”), paper, TYVEK® type sheet material, and the like. If adhesive is used to secure the count sheet holder 100 to a sterilization wrap or tray, various types of adhesive can be used, including acrylic copolymer, hot melt adhesive, and the like. Count sheet holder 100 can be provided in a variety of shapes, such as square or elongate and rectangular. As to dimensions, enclosure is preferably about 4.75 by about 3.25 inches overall, although other dimensions may be used as a matter of preference. The material of count sheet holder 100 preferably permits writing thereon (such as with permanent marker). For steam sterilization, count sheet holder 100 is preferably applied prior to sterilization. For plasma, hydrogen peroxide or ozone sterilization, count sheet holder 100 is preferably affixed post-sterilization, as paper material inside enclosure may cause the sterilization unit to abort, particularly if an adhesive or zipper closure is not used. When a wrapped container is delivered to the O.R., the circulating nurse preferably removes the count sheet 170 from the count sheet holder count sheet holder 100 rather than removing the enclosure from the wrap 150, as the wrap 150 could be torn in the process, thereby compromising the sterility of the contents of the sterilization tray. However, it will be appreciated that count sheet holder can nonetheless be applied and filled with count sheet holder before or after sterilization, as desired. The count sheet can be made from a cellulose-based material or non-cellulose based material, such as spun bonded polypropylene, sold under the trade name of Tyvek®. Any count sheet holder described herein can be disposed after the sterilization step, or reused in a subsequent sterilization operation.
A second embodiment of a count sheet holder is illustrated in FIGS. 4-10, which is preferably configured for use with a sterilization container, rather than a wrapped sterilization tray. As illustrated in FIG. 4, count sheet holder 200 is provided that is configured to attach to a handle 166 of a container 160. The particular configuration of count sheet holder 200 is illustrated in FIGS. 5-10. As can be seen, count sheet holder 200 includes a cover portion 210 attached to a body portion 220 by a hinge member 230 that cooperate to define an enclosure 240 for containing a count sheet 170. Cover portion 210 includes a front face 208, a back face 212, and a perimeter bead 214 that is received by a complementary bead 224 in body portion 220, more clearly illustrated in FIG. 10. It will be appreciated that other types of suitable closures can be used. A plurality of vents 218 are provided to permit air or other gas to be evacuated from compartment 240. One or more tabs 216 can be provided to facilitate opening count sheet holder 200 after sterilization, and can also act to hold the enclosure closed if suitably configured, such as with a buckle or the like.
A zip tie, elastic loop or further attachment strap can be used to attach count sheet holder 200 to tray 160. For example, a strap with hook and loop fastener can be provided to selectively attach to holder 200 and to a handle 166 of a container 160. Alternatively, an attachment tab 250 can be provided for attaching holder 200 to a sterilization container, wherein a tip 252 is provided at a distal end of tab 250 having a plurality of barbs 254 for engaging opening 256 in tab after tab 250 is wrapped, for example, about the handle 166 of container 160. FIG. 7 illustrates back 228 of body portion and FIG. 8 illustrates one of the vents 218. FIG. 9 is a cross-sectional view illustrating enclosure/compartment 240. Count sheet holder 200 can be made from a variety of materials, including silicone rubber and other materials such as a thermoplastic elastomer or polypropylene. Count sheet holder 200 is preferably of dimensions of about 3.25 inches by about 2.5 inches overall, such that holder 200 is suitable to contain a 8½ by 11 inch sheet of paper folded into a smaller size. It will be appreciated that count sheet holder 200 is preferably reusable, whereas count sheet holder 100 is preferably a disposable item that is disposed with the sterilization wrap.
A further embodiment of a count sheet holder 300 is illustrated in FIG. 11. Count sheet holder 300 is a generally envelope-like structure made from a preferably transparent first layer 310 bonded to a preferably transparent second layer 320 via a peripheral seal 314 defining an opening 312 for receiving a count sheet 170. Indicia relating to use 316 and non-sterility of the count sheet 317 can also be provided. A strap 360 is routed through two openings 350 after insertion of the count sheet and used to attach the holder 300 to the handle 166 of a sterilization container 160. Holder 300 can be made from a variety of materials and manners as described with respect to embodiments 100, 100′, which are preferably disposable and 200, which is preferably reusable. Accordingly, holder 300 may be configured to be disposable or reusable. If desired, strap 360 can be unitary with the holder 300 wherein the strap 360 can be routed around the handle, through openings 350, and then attached either to itself or another portion of holder 300.
For purposes of further illustration, and not limitation, FIGS. 12-14 present a further representative embodiment of a count sheet holder 400 in accordance with the present disclosure. Count sheet holder 400, as illustrated, is a generally rigid reclosable box. FIGS. 12-13 illustrate count sheet holder 400 in an open condition, while FIG. 14 illustrates count sheet holder in a closed condition.
As illustrated, count sheet holder 400 includes a cover portion 420 attached to a body portion 410 by a hinge 425 that attaches the cover portion to the body portion. The body portion 410 and cover portion 420 cooperate to define a compartment 430 for containing a count sheet (e.g., 475, FIG. 14(D)) when the cover is closed, and a fastener 440 for fastening the count sheet holder to a sterilization container (e.g., 160). FIG. 12(A) illustrates a plan view of the count sheet holder in an open condition illustrating the exterior planar surfaces 412, 422 of the cover portion 420 and base portion 410 of the count sheet holder 400. FIG. 12(B) illustrates a top view of the count sheet holder, particularly illustrating longitudinal edge walls 414, 424 of the base portion 410 and cover portion 420, respectively.
