DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] Referring now to the drawings and the illustrative embodiments depicted therein, a vertical storage system 10 provides for vertical storage of elongate articles 12, such as esophageal dilators (FIG. 1). The storage system 10 includes a gripping element 14 in the form of a flexible sheet material having a plurality of receiving slots or apertures 16 for gripping and statically holding elongate articles 12. The gripping element 14 is supported by a support cassette or support frame 18. The support frame 18 includes a hollow elongate rectangular frame defined by a rigid bottom support panel 20, a top plate 21, a first side plate 23, and a second side plate 25. The support panel 20, top plate 21, and side plate 23, 25, are mechanically fastened such that the support frame 18 is sufficiently rigid to support the weight of a plurality of elongate articles 12. The bottom support panel 20 of support frame 18 includes a pattern of holes 22 linearly spaced along the length of the panel 20. The gripping element 14 rests on the top of the support panel 20 and is held in position by a securing plate 24 which is positioned on top of the gripping element 14 so that the gripping element 14 is held between bottom support panel 20 and securing plate 24 (FIGS. 1 and 2). Like support panel 20, the securing plate 24 defines a pattern of holes 26, each of the holes 26 generally corresponding to the location of holes 22 of the bottom support panel 20 (FIGS. 2 and 3), and the holes 22, 26 corresponding to the locations of apertures 16 formed in the gripping element 14. The securing plate 24 may be removable from the support frame 18 in order to remove and clean or replace the gripping element 14. The support frame 18 may be made of metal, plastic, composite, or other rigid material suitable for sterile storage.

[0022] Patterns of gripping slots or apertures 16 are cut or formed into the gripping element 14 and each aperture 16 defines a plurality of gripping fingers 31 (FIGS. 2 and 3). The receiving apertures 16 are disposed such that their centers are substantially aligned with the centers of the holes 22 of the rigid support panel 20 and the holes 26 of the securing plate 24, thus allowing end portions of the elongate articles 12 to pass through the bottom support panel 20, through openings formed by the apertures 16 in the gripping element 14, and through the securing plate 24.

[0023] The receiving apertures 16 are each configured to allow one of the elongate articles to at least temporarily form an opening in the gripping element 14 due to an entry or insertion force, causing the gripping fingers 31 to give way around the elongate article 12. The gripping fingers 31 of the gripping element 14 then grip or frictionally engage around the elongate article 12, thus providing a friction interaction between the exterior 27 of the elongate article 12 and exterior surfaces 29 of the gripping fingers 31, such as shown in FIGS. 2 and 3. The material of the gripping element 14 is sufficiently stiff and provides sufficient friction force between the gripping fingers 31 and the elongate article 12 to support the full weight of the suspended article 12, substantially without crushing or piercing or otherwise permanently deforming or damaging the structure of the elongate article 12.

[0024] As best shown in FIGS. 1 and 2, the receiving apertures 16 of the illustrated embodiment are formed by selectively opening a cruciform or cross pattern of slits cut into the gripping element 14, although it will be appreciated that the apertures 16 may be formed with different patterns, such as circles, rectangles, triangles, squares, cruciform, star patterns, or the like. The receiving apertures 16 are capable of accommodating various sizes of elongate articles 12, including a constant-diameter tail end 12a of an elongate article 12 and a tapered leading end 12b of an elongate article, such as shown in FIG. 3. The apertures 16 may be a slit pattern having substantially no void or opening in its relaxed or non-deflected state when not engaged by an elongate article (see the left side aperture in FIG. 2 and the right side apertures in FIG. 1) such that a void or opening in the receiving apertures 16 is first created during insertion of the elongate article 12. However, it is further envisioned that the apertures may have some initial width or separation between the adjacent gripping fingers, and/or that other shapes of non-slotted openings may be used, without departing from the spirit and scope of the present invention.

[0025] The flexible sheet material of gripping element 14 may be composed of rubber, plastic, composite, silicone, or similar flexible material, and preferably a material approved by the U.S. Food and Drug Administration (FDA) for medical use, optionally with antimicrobial properties. The flexible sheet material of gripping element 14 preferably has physical properties including sufficient surface friction to grip the exterior of an elongate article 12, being cleanable by cleaning solutions commonly used for reusable medical devices without absorbing the cleaning solutions, resistance to permanent deformation, readily elastically deformable, resistance to tearing, resistance to moisture absorption, resistance to degradation in the presence of ultraviolet (UV) light, and the like. It will be appreciated that the gripping element 14 may be formed of a uniform material throughout or may be formed of a composite of materials, such as various grades of silicone, or a combination of plastic and silicone, etc. For example, the peripheral regions of the gripping element 14 may be a rigid plastic while the gripping element portions on the central region of the element 14 may be flexible silicone, wherein the flexible silicone is mechanically or chemically coupled to the rigid plastic. It will also be appreciated that the gripping element 14 may be self-supporting within the support frame 18, such that the rigid bottom support panel 20 may be omitted. For example, the gripping element 14 may have sufficient structural rigidity to support its own weight and the weight of the elongate articles engaged with the element 14, while still allowing for a user to remove or insert elongate articles into the receiving apertures 16.

[0026] In the embodiment of FIG. 4, a plurality of support frames 18 are disposed inside a portable cabinet 28 having a door 30, a top panel 32, a bottom panel 34, a right side panel 36, a left side panel 38, and a back panel 40, all cooperating to define the cabinet 28. Optionally, and as shown, a plurality of frame members 42 form a frame of the cabinet 28, with each frame member 42 coupled between the top panel 32 and the bottom panel 34, with the right side panel 36, the left side panel 38, and the back panel 40 disposed between the frame members 42. Optionally, the side panels 36 and 38 and the back panel 40 may be attached to the exterior side of the frame members 42. The door 30 is mounted by a hinge 44, which is fixed to either the edge of the left side panel 38, right side panel 36, or a frame member 42. The cabinet 28 is supported by locking wheels 46 attached to the bottom of the bottom panel 34 to allow the cabinet to be maneuvered, such as from one operating room to another operating room.

[0027] The support frames 18 within cabinet 28 may be slideably supported by slidable mounting rails 50 that are mechanically fixed onto each side of the support frame 18 (FIGS. 5 and 6). The slidable rails 50 enter into respective fixed mounting rails 52 (FIG. 7) that are mechanically fixed within the cabinet 28, thus enabling the support frame 18 to be slid outward relative to the cabinet 28, such as shown in FIG. 5. The fixed rails 52 are mechanically attached within the cabinet 28 at the bottom surface of the top panel 32. The sliding rails 50 are configured such that when the door 30 is in an open position the support frame 18 may slide out of the opening exposed by the open door to allow access to all elongate articles 12 stored on that frame, such as shown in FIG. 6. The support frames 18 within cabinet 28 each include an end plate handle 54 attached to the front of the support frame, to allow a user to pull the slideably mounted support frame 18 outward from the cabinet 28. The support frames 18 each include a lower divider 48 configured to provide separation between the suspended ends of elongate articles 12 stored on the respective support frames 18. The lower divider 48 is supported by vertical supports 49, one vertical support 49 connected to each end of the support frame 18 as shown in FIG. 7. The lower divider 48 has a plurality of divided openings 48a defined by a plurality of horizontal dividing fingers 48b. Optionally, vertical divider sheets or screens may be disposed between support frames 18 and lower dividers 48 to ensure separation of the articles 12 even while moving the cabinet 28.

[0028] In another embodiment, a vertical surface-mountable cabinet 56 supports a set of two support frames 18, such as shown in FIGS. 8 and 9. The cabinet 56 includes a rear panel 58, a rectangular main frame 60, and a hingedly mounted door 62 (FIG. 8). The rear panel 58 includes mounting holes 64 that facilitate mounting the cabinet 56 to a vertical surface, such as a wall. The door 62 includes a door panel 66 and a rectangular door frame 68. The door 62 is fixed to the main frame 60 with a vertically oriented hinge 70. A support frame 18 is fixedly mounted to the top of the main frame 60 to provide vertical storage of elongate articles 12 (FIGS. 8 and 9). Another support frame 18 is fixedly mounted to the top of the door frame 68 to provide vertical storage of additional elongate articles 12, such that the door-mounted support frame 18 and the other support frame 18 that is mounted on the main frame 60 reduce the likelihood of contact or interference of the stored elongate articles 12 when the door is open, closed, or moving between opened and closed positions.

[0029] Disinfecting elements, such as a disinfecting light 47, may be provided for use with the storage system 10, such as mounted on the interior of the portable cabinet 28 (FIG. 4) or on the interior of the cabinet 56 (FIG. 8). The disinfecting elements provide infection and contamination control of the stored elongate articles 12. Disinfecting elements may emit ultraviolet light (less than about 400 nm wavelength) or violet or near-ultraviolet light (about 405 nm wavelength). The disinfecting elements are provided for destroying biological pathogens on the stored elongate articles, the interior structures of the storage apparatus, and in the air within the storage apparatus. Such pathogens may include bacteria, viruses, mold, and the like. The disinfecting light may include an individual bulb, as shown, or may include a string or strand of multiple lights, or one or more tubular elongate lights.

[0030] Accordingly, the vertical storage system of the present invention provides vertical storage for elongate articles, such as medical dilators. The storage system provides a simple and effective storage solution for elongate articles, for keeping the dilators clean, orderly, and readily removable and replaceable. The storage system includes a flexible sheet of material having receiving slots or apertures that form fingers or edges to grip the exterior of an elongate article with sufficient gripping force to maintain each article in a vertical orientation until it is removed by a downward pulling force. The gripping force is accomplished via the gripping fingers or elements at the aperture pattern and the physical properties of the flexible material, such as elastic deformability and exterior friction coefficient. The storage device may be disposed inside a container for convenient access, transportation, and protection from contamination. The storage device may also include disinfecting lights to further decrease contaminants on the stored elongate articles.

[0031] Changes and modifications in the specifically described embodiments can be carried out without departing from the principles of the present invention, which is intended to be limited only by scope of the appended claims, as interpreted according to the principles of patent law, including the doctrine of equivalents.
