STACKABLE ENDOSCOPE STORAGE TRAY AND METHOD OF USE

BACKGROUND

Endoscopes are well-known in the art and are commonly used for numerous medical procedures. After each use, an endoscope will undergo reprocessing by cleaning, disinfection and/or sterilization to reduce or prevent contaminants from settling onto the endoscope, as well as to prevent the spread of disease, viruses, bacteria, and illness.

After endoscope reprocessing, an endoscope is generally disposed in a stress-free state within a clean tray that has been cleaned in a cart washer, where fluid, chemicals and/or heat are applied to the tray in order to decontaminate the tray. However, due to high temperatures, trays can deform during washing. After the endoscope has been disposed within the clean tray, a cover and/or a lid can be secured to the perimeter of the tray. The tray can then be stacked one on top of another where it can be then transported by hand or stacked in a cart and then transported to a procedure or storage room. After the endoscope is used, or the shelf-life of the contents of the tray has expired, the tray can be stacked one on top of the other and transported back for reprocessing.

During transport, the stacked trays can move, increasing the chances of the endoscopes stored within the trays being damaged. Further, movement of the stacked trays can make transport more difficult since the stacked trays may slide with side to side movement. This side to side or lateral movement may cause damage to the endoscope during transport. If one or more trays fall, the endoscope can be further damaged or the endoscope may be placed in a different tray all together, which may lead to difficulties in tracking the endoscope before or after use and risk potential cross-contamination among patients undergoing an endoscope procedure. While some known brands of trays can be stacked, these trays are not locked together in a mating engagement to prevent movement.

Thus, there is a need to develop a new tray, systems and methods where endoscope trays can be stacked in a mating engagement to lock the trays together to improve tray portability during transport and storage. There is also a need to provide stackable trays that reduce side to side movement of the trays when transported. There is also a need to develop a tray that is cart washer compatible so that the tray does not deform during washing.

While most of the terms used herein will be recognizable to those of ordinary skill in the art, it should be understood that when not explicitly defined, terms should be interpreted as adopting a meaning presently accepted by those of ordinary skill in the art.

In some embodiments, a tray is provided that has a feature such as a recess and/or a projection within a base of the tray and on an upper surface of a lid to allow for tray and lid engagement. This engagement or interface between the tray and the lid will prevent sliding of the base of the tray on the upper surface of the lid which will improve portability. In some embodiments, the recess and/or projection on the tray will also provide increased strength to the base of the tray and the recess and/or projection on the lid will provide increased strength to the lid to decrease the likelihood of tray and lid deformation during a cart washing cycle at elevated temperatures.

In some embodiments, a tray is provided that is cart washer compatible and that is chemical and heat resistant. In some embodiments, dimensions of the tray can be sufficient to accommodate substantially all sizes of flexible medical endoscopes in a coiled state without undue stress being applied to the flexible portions of the endoscope. However, the tray can also be sufficiently small to permit it to be easily carried by a person. In some embodiments, the tray is constructed and dimensioned to provide support for the endoscope coiled in a stress-free state.

In some embodiments, the tray is rigid and re-usable and comprises a base having planar and non-planar portions and surrounding sidewalls upstanding therefrom, the tray being formed of a semi-rigid material capable of withstanding repeated disinfection and dimensioned to provide support for a flexible medical endoscope coiled in a stress-free state.

In some embodiments, the tray is designed to prevent contact of sensitive areas of an endoscope from coming into contact with each other during storage and transportation which prevents damage to the endoscope.

Tray

Referring to FIGS. 1-21, an endoscope tray 20 is provided. The tray is configured to store a flexible medical endoscope 22 and to be matingly stacked with other compatible trays having a corresponding lid 24 to improve stability and portability during transport. The tray can be rigid and reusable and can be formed of a semi-rigid material capable of withstanding repeated disinfection and dimensioned to provide support for the endoscope coiled in a stress-free state.

The tray includes an interior 26 for storage and/or reprocessing of the endoscope, as shown in FIG. 2. The interior is defined by an inner surface 28 that forms a base 30 and surrounding sidewalls 32 upstanding therefrom. The sidewalls can be continuous and monolithic with the base of the tray. The sidewalls can include openings or handles 34 to assist a user in moving and/or carrying the tray. In some embodiments, a portion of the opening or handle can be formed from a side 35 of the lid, as shown in FIG. 1.

As shown in FIG. 3, the tray can include a rim 36 and a peripheral lip 38 disposed at least partially around the surrounding sidewalls and extending outwardly therefrom. The rim and/or the lip are configured for engagement with a perimeter 48 of the lid so that the lid covers the tray, as shown in FIG. 1. The lid can have a friction fit engagement with the tray when covering the tray. In some embodiments, the lid can self-seal with the rim of the tray by a natural vacuum created when the lid is mated with the tray.

The tray includes a bottom exterior surface 40, as shown in FIG. 6. The bottom exterior surface is configured to mate with the lid when the tray is stacked on top of the lid. The bottom exterior surface of the tray includes one or a plurality of recesses 41 and/or projections 42 that are configured to mate with one or a plurality of recesses 43 and/or projections 44 formed from an exterior surface 46 of the lid, as shown in FIGS. 5-8. It is to be understood that one or a plurality of projections defined from the tray will mate with corresponding one or a plurality of recesses defined from the lid and one or a plurality of recesses defined from the tray will mate with corresponding one or a plurality projections defined from the lid.

Mating engagement of the recesses and/or projections of the tray and the lid reduces lateral side to side movement of the tray when the bottom exterior surface of the tray is stacked on the exterior surface of the lid. The mating engagement of the recesses and/or projections of the tray and the lid creates a locked engagement, thereby allowing a user to lift one or multiple trays with lids together as a single unit so that the trays and lids can be moved from one location to another location without detaching. The mating engagement described above also reduces the probability of an endoscope being dropped or contaminated during transport. It is to be understood that the lid can mate with the recesses and/or projections of the tray when the tray is uncovered, as shown in FIG. 3.

The recesses and/or projections of the tray, in some embodiments, are configured to provide increased strength to the bottom exterior surface of the tray and the recesses and/or projections of the lid provide increased strength to the lid to help prevent deformation during reprocessing such as a cart washing cycle at an elevated temperature.

The recesses and/or projections of the bottom exterior surface of the tray and the lid can be friction fittings that when mated, reduce lateral side to side movement of the tray, as described above and shown by the arrows in FIG. 7. The recesses and/or projections can also have a male/female engagement, tab/slot engagement, snap engagement, and/or compressive engagement. The bottom exterior surface of the tray and/or the exterior surface of the lid can have 1 to about 100 recesses and/or projections. In some embodiments, the bottom exterior surface of the tray and/or the exterior surface of the lid can have 1 to about 80, 1 to about 75, 1 to about 60, 1 to about 50, 1 to about 40, 1 to about 25, 1 to about 20, 1 to about 15, 1 to about 10, 1 to about 5 or 1 to about 2 recesses and/or projections. The tray and/or the lid can have 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95 to about 100 recesses and/or projections.

The recesses and/or projections can be arranged in a pattern shape and/or can include geometric shapes, as shown in FIGS. 1-21. For example, as shown in FIGS. 1-8, the tray includes a pattern shaped projection and square shaped recesses disposed within a center of the tray and the lid includes a corresponding pattern shaped recess and square shaped projections disposed within a center of the lid. The pattern shaped projection of the tray will mate with the corresponding pattern shaped recess of the lid and the square shaped recesses of the tray will mate with the corresponding square shaped projections of the lid to matingly lock the tray with the lid, as shown in FIG. 6-8.

As shown in FIGS. 9-14, the tray can include a pattern shaped projection and circular shaped recesses and the lid includes a pattern shaped recess and circular shaped projections. The pattern shaped projection of the tray will mate with the corresponding pattern shaped recess of the lid and the circular shaped recesses of the tray will mate with the corresponding circular shaped projections of the lid to matingly lock the tray with the lid, as shown in FIG. 12-14.

As shown in FIG. 15, the tray can include a pattern shaped projection with square and rectangular shaped recesses and the lid can include a pattern shaped recess with square and rectangular shaped projections. The pattern shaped projection of the tray will mate with the corresponding pattern shaped recess of the lid and the square and rectangular shaped recesses of the tray will engage with the corresponding square and rectangular shaped projections of the lid to mate, locking the tray with the lid.

As shown in FIG. 16, the tray can include a pattern shaped projection and triangular shaped recesses and the lid can include a pattern shaped recess and triangular shaped projections. The pattern shaped projection of the tray will mate with the corresponding pattern shaped recess of the lid and the triangular shaped recesses of the tray will engage with the corresponding triangular shaped projections of the lid to mate, locking the tray with the lid.

The tray can include star shaped projections and the lid can include star shaped recesses, as shown in FIG. 17. The tray can include pentagonal shaped projections and the lid can include pentagonal shaped recesses, as shown in FIG. 18. The tray can include hexagonal shaped projections and the lid can include hexagonal shaped recesses, as shown in FIG. 19. The tray can include cross shaped projections and the lid can include cross shaped recesses, as shown in FIG. 20. The tray can include diamond shaped recesses and the lid can include diamond shaped projections, as shown in FIG. 21. It is to be understood that the shaped configurations of the recesses and projections on the tray and the lid of FIGS. 15-21 can be the reverse of what is described above. For example, rather than the tray having star shaped projections and the lid having star shaped recesses, the tray can have star shaped recesses and the lid can have star shaped projections.

It is contemplated that the recesses and/or projections can be any shape such as geometric or otherwise, and can be a mix of shapes disposed on a single tray and/or lid. Shapes include, but are not limited to a nonagon, octagon, heptagon, hexagon, triangle, scalene triangle, right triangle, parallelogram, rhombus, square, pentagon, circle, oval, heart, cross, arrow, cube, cylinder, star, crescent, a wavy line, semicircular, ring, quatrefoil shaped or a combination thereof. The shapes can be regular, irregular and/or freeform.

It is further contemplated that the tray and the lid can each include both recesses and projections or recesses or projections. The recesses and/or projections can be oriented in a discrete or a random pattern on the bottom exterior surface of the tray and/or the exterior surface of the lid. The recesses and/or projections can cover the entire bottom exterior surface of the tray or only portions of the bottom exterior surface of the tray. Similarly, the recesses and/or projections can cover the entire exterior surface of the lid or only portions of the exterior surface of the lid.

The recesses and/or projections can have various surfaces configurations such as, smooth, rough, arcuate, undulating, porous, semi-porous, dimpled, knurled, polished and/or textured. The recesses and/or projections can also be a certain size, such as, for example, from about 1 millimeter (mm) to about 4 inches in length, width, thickness and/or height. It is contemplated that the recesses and/or projections can be from about 1, 5, 10, 15, 20, 25 mm, 1, 2, 3 to about 4 inches in length, width, thickness and/or height.

The recesses and/or the projections of the tray can be spaced apart a certain distance from each other on the bottom exterior surface of the tray. For example, each recess and/or projection can be 1 mm to about 10 inches from each other. In some embodiments, each recess and/or projection can be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25 mm, 1, 2, 3, 4, 5, 6, 7, 8, 9 and/or 10 inches from each other on the bottom exterior surface of the tray. In a similar manner, the recesses and/or projections of the lid can be spaced apart a certain distance from each other on the exterior surface of the lid. For example, each recess and/or projection can be 1 mm to about 10 inches from each other, as described above. It is to be understood that the distance between each recess and/or projection of the tray will be equal to and correspond to the distance between the recesses and/or projections located on the lid so that the tray and lid matingly engage.

It is contemplated that more than one tray and one lid can be implemented. For example, 1 to about 10 trays and 1 to about 10 lids can be used and stacked together. In some embodiments, 1, 2, 3, 4, 5, 6, 7, 8, 9 to about 10 trays and 1, 2, 3, 4, 5, 6, 7, 8, 9 to about 10 lids can be stacked together in a mating engagement, which locks the trays with the lids.

The recesses and/or projections of the tray and/or the lid can be vacuum formed or injection molded. The recesses and/or projections can also be monolithic to the exterior surfaces of the tray and lid or can be in an over-molded configuration. It is to be understood that in some embodiments, the mold or shape of the recesses and/or projections will be seen within the interior of the tray molded into the base, as shown in FIG. 2.

Once the trays and lids of the present application are assembled and stacked, side to side or lateral movement will be eliminated or reduced, which reduces damage to the endoscope stored within the tray during transport. The stacked trays can more easily be transported by hand or in a cart or cabinet to the desired area as there is more stability to the stacked trays.

Because the trays and lids of the present application are more stable when stacked, the risk of one or more trays falling is reduced, which reduces further damage to the endoscope during transport. The more stable storage and transport of endoscopes in the trays also reduces or prevents the chance of an endoscope falling out of the tray and being misplaced in a different tray, which may lead to difficulties in tracking the endoscope before or after use. Tracking of the endoscope is essential for quality assurance purposes and for patient tracing to avoid cross-contamination among patients.

The tray can be made from a material such as, for example, a polymeric material. The polymeric material can be thermoplastic and/or is a polycarbonate. For example, the tray can be fabricated from materials such as machined or injection molded thermoplastics such as polyaryletherketone (PAEK) including polyetheretherketone (PEEK), polyetherketoneketone (PEKK) and polyetherketone (PEK), carbon-PEEK composites, PEEK-BaS04 polymeric rubbers, polyethylene terephthalate (PET), fabric, silicone, polyurethane, silicone-polyurethane copolymers, polymeric rubbers, polyolefin rubbers, semi-rigid and rigid materials, elastomers, rubbers, thermoplastic elastomers, thermoset elastomers, elastomeric composites, polyphenylene, polychloropene, polyamide, polyetherimide, polyethylene, epoxy, partially resorbable materials, totally resorbable materials, polyglycolide, polytyrosine carbonate, polycaprolactone, silicone based rubber, liquid silicone rubber, High Consistency Rubber, silicon, TPE, Polypropylene, Polycarbonate, ABS or any combination thereof. The tray can also be made from steel, aluminum, paper, bamboo, cork, glass, hemp or any combination thereof.

In some embodiments, the tray can have a certain length, width and height. In some embodiments, the length of the tray can be from about 16 to about 34 inches, the width can be from about 12 to about 24 inches and the height can be from about 3 to about 8 inches. In some embodiments, the length of the tray can be from about 16, 18, 20, 22, 24, 26, 28, 30, 32 to about 34 inches, the width of the tray can be from about 12, 14, 16, 18, 20, 22 to about 24 inches, and the height of the tray can be from about 3, 4, 5, 6, 7 to about 8 inches.

The components of the tray, individually or collectively, may also be fabricated from a heterogeneous material such as a combination of two or more of the above-described materials. The tray as described herein may be constructed of a suitable biocompatible material to impart various desirable characteristics, such as rigidity, and resilience.

Components of the tray can also be made from a suitable material such as for example, polyurethane, polyurea, polyether(amide), PEBA, thermoplastic elastomeric olefin, copolyester, styrenic thermoplastic elastomer, carbon fiber, glass fiber, ceramics, methacrylates, poly (N-isopropylacrylamide), plastic (e.g., polycarbonates), ABS, MABS, or the like or combinations thereof.

Storage System

Referring to FIGS. 1-31, a stackable tray system 50 for storage of an endoscope(s) is provided. The system comprises a tray 20, endoscope 22 and lid 24, as described above. For example, as shown in FIGS. 1, 9 and 15-21, the system can include a first tray 20 having a first lid 24 configured to cover the first tray, and a second tray 20 having a second lid 24 configured to cover the second tray. The recess and/or projection of the exterior surface of the first lid of the first tray is configured to mate with the recess and/or projection of the bottom exterior surface of the second tray when the first tray and the second tray are stacked together to reduce lateral side to side movement of the first tray and the second tray. It is to be understood that the first lid and the second lid are interchangeable or the first lid and the second lid are not interchangeable. As described above, one or more trays and lids can be implemented with the system such as 1 to about 10 trays and 1 to about 10 lids.

The system can include a liner 52, as shown in FIGS. 22-23. The liner is configured to engage with the interior of the tray and the endoscope, as shown in FIG. 23. The liner can be configured to engage contours of the interior and rim of the tray. In some embodiments, the liner is similar to the liner found and described in U.S. Pat.

The tray interior and portions of the exterior of the tray can be engaged by the liner. The liner can be made of a flexibly deformable material substantially impermeable to fluids. The disposable liner can contact the bottom surface of the tray and at least partially encloses the reprocessed endoscope. In some embodiments, the liner is a disposable single use liner that may be sterile or unsterile.

The disposable liner can be configured to temporarily line the entirety of the interior of the tray and prevent the endoscope from having direct contact with the interior of the tray. In some embodiments, the liner prevents moisture from the reprocessed endoscope from contacting the tray and when the tray is used repeatedly, it prevents or reduces contamination from one endoscope to the next endoscope. In some embodiments, the disposable liner can be in a sheet or bag configuration.

The tray whether it is lined or not lined can be temporarily covered with a disposable cover 54, as shown in FIGS. 24-30. The cover can be a puncture resistant flexible cover configured to enclose or partially enclose the tray when it is covered or uncovered with the lid. As shown in FIG. 24, the cover can enclose the tray and the lid, or the cover can enclose the tray and the lid can be disposed on top of the cover to close the tray, as shown in FIG. 25.

The disposable cover can at least partially enclose or entirely enclose the reprocessed endoscope and the tray. The cover can be a disposable single use cover that may be sterile or unsterile. In some embodiments, the cover can be similar to the cover found and described in U.S. U.S. Pat. No. 6,749,063, assigned to Cantel (UK) Limited. This patent is herein incorporated by reference.

The cover can include a flexibly deformable sheet material substantially impermeable to fluids. The flexibly deformable sheet material can be configured to be temporarily secured to the tray so as to cover at least the interior of the tray.

In some embodiments, the recess and/or projection of the first tray and the second tray and/or the recess and/or projection of the first lid and the second lid are vacuum formed or injection molded. In some embodiments, the first endoscope and the second endoscope are reprocessed and stored in the interior of the first tray and the second tray. In some embodiments, the first tray and the second tray are stored in a washer compatible cart.

In some embodiments, components of the system described above may be made by injection molding, compression molding, blow molding, thermoforming, die pressing, slip casting, electrochemical machining, laser cutting, water-jet machining, electrophoretic deposition, powder injection molding, sand casting, shell mold casting, plaster-mold casting, investment casting, vacuum casting, permanent-mold casting, slush casting, pressure casting, die casting, centrifugal casting, squeeze casting, rolling, forging, swaging, extrusion, shearing, spinning, or combinations thereof.

In some embodiments, the components of the system may be formed by 3D printing. The terms “three-dimensional printing system,” “three-dimensional printer,” and “printing,” describe various solid freeform fabrication techniques for making three-dimensional articles or objects by selective deposition, jetting, fused deposition modeling, multi-jet modeling, and other additive manufacturing techniques now known in the art or that may be known in the future that use a build material or ink to fabricate three-dimensional objects.

Instructions in the form of schematics encompassing any of the embodiments disclosed herein may be given to a computer to be carried out by a 3D printer. In some embodiments, components of the system may be color coded to signify various properties.

Components of the system may be sterilizable. In various embodiments, one or more components of the system are sterilized by gas sterilization, such as, for example, with ethylene oxide or steam sterilization.

In various embodiments, one or more components of the system are sterilized by radiation in a terminal sterilization step in the final packaging. Terminal sterilization of a product provides greater assurance of sterility than from processes such as an aseptic process, which require individual product components to be sterilized separately and the final package assembled in a sterile environment.

Typically, in various embodiments, gamma radiation is used in the terminal sterilization step, which involves utilizing ionizing energy from gamma rays that penetrates deeply in the device. Gamma rays are highly effective in killing microorganisms, they leave no residues nor have sufficient energy to impart radioactivity to the device. Gamma rays can be employed when the device is in the package and gamma sterilization does not require high pressures or vacuum conditions, thus, package seals and other components are not stressed. In addition, gamma radiation eliminates the need for permeable packaging materials.

In various embodiments, electron beam (e-beam) radiation may be used to sterilize one or more components of the system. E-beam radiation comprises a form of ionizing energy, which is generally characterized by low penetration and high-dose rates. E-beam irradiation is similar to gamma processing in that it alters various chemical and molecular bonds on contact, including the reproductive cells of microorganisms. Beams produced for e-beam sterilization are concentrated, highly-charged streams of electrons generated by the acceleration and conversion of electricity.

In various embodiments, a kit or system is provided that may include additional parts along with one or more trays and lids combined together to be used with the cart. The kit may include one or more trays in a first compartment. A second compartment may include one or more lids. A third compartment may include one or more liners. A fourth compartment may include one or more covers. A fifth compartment may include cleaning solutions, gloves and other procedural supplies for performing cleaning of the endoscope, as well as an instruction booklet or notification of a website where instructions for using the kit or system can be located. Each component of the system or kit may be separately packaged in a plastic pouch. A cover of the kit may include illustrations of the use of the cover and a clear plastic cover may be placed over the compartments to maintain sterility.

From the foregoing description, one of ordinary skill in the art can easily ascertain the essential characteristics of this disclosure, and without departing from the spirit and scope thereof, can make various changes and modifications to adapt the disclosure to various usages and conditions. The implementations described hereinabove are meant to be illustrative only and should not be taken as limiting of the scope of the disclosure, which is defined in the following claims.
