DESCRIPTION OF THE PREFERRED EMBODIMENTS

(9) The systems, devices, and methods described herein generally include a lined storage bin comprising a container, a venting grommet, and a liner bag. In an embodiment, the systems, devices, and methods may further comprise a bag storage and dispensing system. The venting grommet is generally sized and shaped to provide a ventilation route for trapped air to escape rapidly from the storage container when displaced by the volume of items disposed in the bin. The venting grommet also generally holds the liner bag in place while also permitting a loose enough fit between the liner bag and the rim that sufficient air may rapidly escape through the ventilation route by passing between the liner bag and the rim without dislodging the bag from the rim.

(10) Such systems can be particularly useful for the storage of medical reuseables, particularly items that may be used multiple times at different points on the same procedure with one patient, but which need to remain sterile (other than for contact with that one patient) during the procedure. They may then be traditionally resterilized or disposed of. These types of devices generally need a semi-sterile location to be placed during the procedure, semi-sterile in that the location is clean with regards to contact with body fluids from other patients, but not clean with regards to body fluids from this patient. The devices also need to remain easily accessible to the person performing the procedure. As a non-limiting example, a medical device such as a surgical clamp may be in this category. The same clamp may be used at multiple points during a procedure without it needing to be cleaned or resterilized (since all contamination is from this patient). However, the clamp cannot be placed on a non-sterile surface or storage device during the procedure, as then it could not be reused with this patient.

(11) Although the present disclosure is generally in conjunction with storing medically contaminated products, tools, or materials, one of ordinary skill in the art will understand this disclosure to encompass other uses for the systems, devices, and methods described herein. The present disclosure is suitable for use in any setting in which it is desirable that a material or tool be sequestered or isolated. By way of example and not limitation, the present disclosure is suitable for use with materials that are, become, or are exposed to, radioactive compounds or materials. Such embodiments may include additional or modified components, including but not limited to liners designed for use in sequestering radioactive materials.

(12) The devices, systems, and methods described herein generally include a storage container, a venting grommet, and one or more bag liners. The devices, systems, and methods described herein also generally include the disposing of potentially contaminated objects by placing such objects in a liner bag lining the interior of a storage container by inserting the objects through the central opening in a venting grommet attached to the rim of the storage container, and placing the venting grommet itself in the liner bag before removing the liner bag from the storage container.

(13) In the depicted embodiment of FIG. 1, an exploded view of a storage bin (102) and a venting grommet (106) is provided. The depicted storage bin (102) is a generally cylindrical container having a hollow interior and two ends (108) and (110), one of which is an open end and the other of which is a generally solid base (110). When the bin (102) is placed for use, the base (110) is normally in contact with the surface on which the bin (102) rests, and the base (110) is generally flat so that the bin (102) stands upright when placed on a flat surface.

(14) In the depicted embodiment, the base (110) is generally sized and shaped similarly to the cross-section of the bin (102) and constructed from the same or similar materials. However, in an embodiment, the base (110) may be sized and shaped differently, such as for fitting into a particular holder designed to accommodate a bin (102), and constructed from or include materials different from those use to construct the bin (102) and/or its subcomponents.

(15) In an embodiment, the base (110) may include a weighting system (not depicted). In such an embodiment, the weighting system moves the center of gravity of the device closer to the surface on which it rests and thus reduces the likelihood of tips, spills, or otherwise dislodging the device from its resting place if jostled or disturbed.

(16) In an alternative embodiment, the base (110) may include a system (not depicted) for increasing the coefficient the friction between the base (110) and the surface on which it rests, also to reduce spills, tips, and dislodging. Such a system may include, without limitation: rubber feet; a friction pad; a friction coating; texturing, shaping, or sizing to increase friction; adhesive; the use of magnets or magnetism; or other systems.

(17) The depicted bin (102) includes a top end opposite the base (110) which has an opening (108) allowing access to the hollow interior of the bin (102). In the depicted embodiment, the top end is narrower than the base (110), forming a second cylindrical shape having a smaller radius than the bin (102) and attached to the bin (102) at the top end. In the depicted embodiment, the exterior of the storage bin (102) near the opening end (108) is threaded (104) such that a threaded venting grommet (106) may be secured to the storage bin (102) by counter-rotating the bin (102) and/or grommet (106) so that the threads (104) of the bin (102) interlock with the threads in the venting grommet (106).

(18) The cylindrical shape of the storage bin (102), particularly the threaded portion (104), allows a threaded venting grommet (106) to be gently coupled to the storage bin (102). Generally speaking, in an embodiment including a threaded interlocking system, the edges of the threads (104) are not sharp, but rather are smooth and rounded to reduce the likelihood that a bag retained between the threads (104) will be damaged or torn when the venting grommet (106) is attached to the storage bin (102).

(19) Although the body of the storage bin (102), as depicted, is generally cylindrical, other shapes and configurations are possible and specifically contemplated, including without limitation polygonal prisms and ellipsoidal configurations. The diameter of the depicted storage bin (102), as well as the height, may vary from embodiment to embodiment, generally depending upon the type of materials or tools with which a given embodiment is to be used.

(20) By way of example and not limitation, where an embodiment is to be used for a lengthy surgical procedure, a larger bin (102) may be necessary to contain all of the disposed materials and/or tools, whereas a smaller bin (102) may suffice for a shorter or less complex procedure. By contrast, in an embodiment for use in an examining room in a family practice clinic, the bin (102) may primarily hold discarded ear swabs, tongue depressors, plastic slip shields, latex gloves, and the like, and a bin (102) with a shorter height or smaller diameter may be sufficient to accommodate the volume of material accumulated.

(21) Similarly, the diameter of the opening (108) will be sized and shaped to accept the materials and/or tools with which the bin (102) is to be used. In general, the diameter of the opening (108) is large enough to allow the materials to enter the storage bin (102) through the opening (108), but the opening will generally be larger than this to provide a larger target into which users can drop materials, thus improving ease-of-use and reducing the amount of contaminated material that contacts the grommet (106).

(22) In the depicted embodiment of FIG. 1, the top opening (108) is about the same diameter as the body of the storage bin (102). This configuration improves the usage of the interior space of the storage bin (102) because the opening (108) is about the same diameter as the bin (102), and the opening (108) can accommodate the passage of items that are also nearly as large as the diameter of the storage bin (102). This is particularly useful where the items to be inserted are not flexible and cannot be bent or deformed to fit through the opening (108).

(23) The storage bin (102) will generally be made of a material known to one of ordinary skill in the art to be suitable for use in cleaning, sterilization and sanitation procedures for the industry or setting in which a given embodiment is to be used. For example, bins (102) for use in medical facilities will generally be made from smooth plastics, stainless steel, porcelain, or other non-porous solids readily cleanable and sterilizable through use of chemicals and other treatments, including without limitation heat and steam.

(24) The apparatus generally also includes a venting grommet (106), such as the embodiment of a venting grommet depicted in FIGS. 1, 2, 5, 6A, 6B, and 7. In the depicted embodiment of FIG. 2, the venting grommet (106) is sized and shaped for attaching to the open end (108) of the bin (102) such that the grommet (106) generally circumscribes the rim. In the depicted embodiment, the venting grommet (106) is generally in the shape of a flat tire.

(25) The venting grommet (106) serves a number of roles. First, the grommet (106) couples to the bin (102) to hold a liner bag (200) in place. The snugness of the fit between the bag (200) and rim (128) generally is loose enough that air within the bin (102) can, when displaced by objects placed in the bin (102), escape from the bin (102) by passing between the bag (200) and rim (128). This fit is generally loose enough that the force of an item disposed in the bin (102) could dislodge the bag (200) from the rim (128), or the force of the rapid ventilation of the air could itself dislodge the bag (200) from the rim (128). The grommet (106) facilitates the ventilation of air from the bin (102) by, among other things, allowing the bag (200) to be disposed on the rim (128) with a sufficiently loose fit to allow ventilation, while holding the bag (200) in place so that it does not slip into the bin (102) when items are placed in it.

(26) The grommet (106) also provides a rigid shield protecting the rim (128) so that materials dropped or thrown into bin (102) do not puncture, tear, or otherwise damage the liner bag (200). Further, the grommet (106) provides a filter of appropriately sized items to place in the bin (102)objects which are too large to fit through the central opening (122) in the grommet are large enough to pose a heightened risk of tearing or puncturing the bag (200) when the bag (200) is removed from the container (102).

(27) The flat tire shape of the depicted venting grommet (106) is formed from a generally circular major arc closed at the end points (124) via a chord (118). The grommet (106) includes a generally circular major arc-shaped inner wall (114 and an outer wall (116), also generally in the shape of a circular major arc. The outer wall (116) generally has a larger radius (612) than the inner wall (114) and is generally concentric with and circumscribes the inner wall (114). These two walls (114) and (116) are generally the same thickness and height and are connected at the top end (112), so that the cross-section of the structure is generally that of an inverted square U-shape as depicted in FIG. 6B. This U-shape provides a channel or pocket sized and shaped to accommodate, accept, and couple with the rim (128) of the bin (102).

(28) The flat portion (118) of the flat tire shape is generally a flat surface or chord (118) connecting the end points (124) of the interior wall (114). In the depicted embodiments, this flat surface (118) does not extend to the outer wall (116), but rather ends at end points (124), to present the inverted square U-shape cross-section for coupling the grommet (106) to the rim (128). This surface (118) is generally a flat elongated rectangular prism with a height about the same as that of walls (114) and (116). Among other things, this element (118) provides additional rigidity and stability to the grommet (106) so that it maintains its shape.

(29) As depicted in FIG. 7, the flat portion (118) also results in a portion of the bag (200) disposed upon the rim (128) to be uncovered (701) by the grommet (106). If the fit between the bag (200) and rim (128) is sufficiently loose, air between the bin (102) and the bag (200) can escape from the bin (102) by passing between the bag (200) and the rim (128) at this uncovered portion (701), but there is little risk of the bag (200) becoming dislodged from the rim (128) or otherwise slipping into the bin (102) because the circular portion of the grommet (106) holds the bag (200) in place along the majority of the circumference of the rim (128). Thus, when an object is placed in the bag (200), the volume of the object displaces a volume of air within the bin (102), and that volume of air can vent from the bin (102) without disturbing the bag (200).

(30) The flat chord (118) also allows the grommet (106) to both circumscribe a majority of the rim (128), which in turn circumscribes the opening (108), while also presenting a sufficiently narrow cross-section to, when rotated along a line generally perpendicular to the plane of the chord (118), pass through the opening (108) into the interior of the bin (102), as depicted in FIG. 5. Because the arc-shape leaves a portion (701) of the bag (200) exposed, as depicted in FIG. 7, the chord (118) also provides some protection to the portion (701) of the rim (128) and bag (200) left uncovered by the grommet (106).

(31) In this fashion, the grommet (106) can itself be placed into the bag (200) lining the bin (102). This has the advantage that a soiled or contaminated grommet (106) need not be placed on and contaminate another surface while the bag (200) is being removed from the bin (102), but rather can be removed and placed directly into the bag (200). Also, because the grommet (106) need not be set aside to change the bag (200), cleaning staff are unlikely to leave a soiled grommet (106) in the treatment room, and thus the risk that subsequent treatments or procedures in that room will be exposed to a contaminated grommet (106) is reduced. This also allows a soiled grommet (106) to be placed in the bag (200) while the bag (200) is still disposed upon the rim (128), meaning the soiled grommet (106) is less likely to contaminate the bin (102) itself when the bag (200) is being changed, as the grommet (106) is itself sequestered prior to removing the bag (200).

(32) In the depicted embodiment of FIGS. 6A and 6B, some details of the venting grommet (106) are provided. FIG. 6A is a bottom elevation view of venting grommet (106). As depicted, the interior wall (114) is generally in the shape of a circular arc closed at the end points (124) by a generally flat rectangular prism (118), and generally circumscribed by the exterior wall (116). The exterior wall (116), unlike the interior wall (114), does not include a closing surface between the end points (126), again so that the cross-section provides the square inverted U-shape for coupling the grommet (106) to the rim (128). The angle (620) of the arc of the interior wall (114) is generally slightly larger than the angle (622) of the arc defining the external wall (116). The radius (610) of the arc defining the interior wall (114) is less than that of the radius (612) defining the arc of the exterior wall (116). As depicted, the arc shape is the major arc between end points (124), not the minor arc. In the depicted embodiment, the end points of walls (114) and (116) are generally coplanar with chord (118), producing the flat tire shape of the grommet (106) when viewed from the top or bottom.

(33) The grommet (106) includes a central opening (122) as depicted in FIGS. 1 and 6, circumscribed in part by walls (114) and (116), through which discarded material is inserted into the storage bin (102) when the device is assembled, as depicted in FIG. 7. In an embodiment, device is assembled by placing a liner bag (200) within the storage bin (102) and then inverting an open end of the liner bag (200) around the opening (108) in the top of the storage bin (102) and dragging the liner bag down around the outside surface of the rim (128), similar to how garbage bags are attached to garbage cans in ordinary domestic use. The liner bag (200) effectively provides a sanitary shield which prevents the rim (128) of the opening (108) from coming into contact with biological material, thus reducing the need to sanitize or clean the rim (128).

(34) Items placed in the bag (200) may pull the bag (200) into the container (102), causing a portion of the bag (200) situated outside of the container (102) to slip inside the container (102), effectively eliminating the shielding function of the bag (200). As described elsewhere herein, the venting grommet (106) may be attached to the top of the storage container (102), sandwiching the bag (200) between the grommet (106) and the rim (128), to hold the bag (200) in place and reduce the likelihood of such slippage by holding the bag (200) in place.

(35) In an embodiment, the venting grommet (106) may be twisted to engage threads (104) on the rim (128) with threads on the venting grommet (106), establishing a more secure connection between the container (102) and the venting grommet (106). In an alternate embodiment, the venting grommet (106) is sized and shaped to attach to the rim (128) without the use of threads, and is held in place through friction between walls (114) and (116) and rim (128). The assembled embodiment depicted in FIG. 7 shows a bag (200) installed in the storage bin (102) and held in place a venting grommet (106) placed over the rim (128) of the bin (102). Contaminated materials may be placed into the storage bin (102) by inserting such materials through the opening (108) and venting grommet (106). The venting grommet (106) will also reduce the likelihood of tearing or ripping of the bag (200) or cracking or damaging the rim (128).

(36) To minimize the amount of the rim (128) which will be exposed (701) when the grommet (106) is attached, the grommet (106) may be sized, shaped, and configured to achieve a long arc-length of walls (114) and (116) while still sizing and shaping the grommet (106) to be capable of being inserted through opening (108) when rotated about 90 degrees around an axis generally perpendicular to chord (118), as depicted in FIG. 5. The longer the arc-length of the walls, the smaller the uncovered portion (701) of the bag (200) and/or rim (128) as seen in FIG. 7. However, as the arc-length of walls (114) and (116) approaches 360 degrees, i.e. a circle, the maximum length of the cross section of the grommet (106) when so rotated also increases, eventually becoming larger than the diameter of the opening (108) such that the grommet (106) can no longer pass through the opening (108) even when so rotated. In an embodiment, the arc-lengths of walls (114) and (116) is optimized to maximize the arc-lengths while still configuring the grommet (106) to pass through the opening (108).

(37) In an alternative embodiment, the grommet (106) may be sized, shaped, and configured such that the largest arc-length of walls (114) and (116) is too large for the grommet (106) to be capable of being inserted through the opening (108) when rotated with respect to the opening as depicted in FIG. 5, unless the size and shape of the opening (108) is deformed or otherwise modified into a generally ellipsoid shape having a major axis large enough to accommodate the insertion of the grommet (106). This deforming or modification may be done through any means, including without limitation manual compression or squeezing.

(40) When it is desired to remove the bag, such as when a procedure, examination or treatment is finished and the material in the storage bin (102) should be discarded or sanitized, the venting grommet (106) is likely to have biological or other material on its surface. As materials are discarded through the opening (108), a portion of the discarded material is likely to come in contact with a part of the venting grommet (106), particularly the interior wall (116), leaving a residue of material. Thus, for the system to remain sanitary, the venting grommet (106) itself may be sanitized or discarded and replaced with a sterile, clean grommet (106). As depicted in the embodiment of FIG. 5, the venting grommet (106) is removed from the rim (128) and inserted into the bag (200) within the storage bin (102) through the opening (108).

(41) Although the outer circumference of the outer wall (116) is greater than that of the rim (128) defining the opening (108), the venting grommet (106) nevertheless can be inserted into the bag (200) through the opening (108) because of the arc shape of the grommet (106). That is, when the grommet (106) is rotated 90 degrees along an axis generally perpendicular to the plane of chord (118), the grommet (106) presents a narrower cross section than when the grommet (106) is oriented for attaching to the rim (128). This allows the grommet (106) to pass through the opening (108) into the bin (102) and/or bag (200). The bag (200) may then be removed from the bin (102) and discarded, or sent for sterilization, where the grommet (106) may be sterilized along with any tools or materials within the bag (200).

(42) Because the rim (128) and the upper portion of the body of the storage bin (102) are protected by the bag (200), the storage bin (102) itself may not generally need to be cleaned, or may require only minimal cleaning and sterilization. The portions of the storage bin (102) that are difficult and time-consuming to clean, such as the threaded (104) rim (128), will not generally require cleaning because they were covered by a bag (200) and the venting grommet (106). This reduces costs and shortens the turnover time for the operating room and its equipment.

(43) In an embodiment, the storage bin (102) is also sized and shaped for housing a bag and/or liner storage and/or dispensing system (300), such as depicted in FIGS. 3-4. In an embodiment, the storage bin (102) further includes a system (300) for storing and dispensing liner bags (200). In the depicted embodiment of FIG. 3, the system (300) includes a spindle (306) attached to a flat, disc-shaped support (310) at one end of the spindle (306) and oriented within the container (102) such that the central axis of the spindle (306) is generally collinear with the central axis of the storage container (102). The bottom of the spindle may be secured to the base (110) of the storage container (102) by a cap (308) which is affixed to the spindle (306) such as by use of adhesive, or hardware. The cap (308) in the depicted embodiment is attached to the exterior of the base (110) and passes through a hole in the base (110) to connect to the spindle (306). The top end of the spindle (306) generally is attached to the support (310) through the use of a second cap (304), which is attached to the spindle (306) in similar fashion to the bottom cap (308).

(44) The support (310) provides a surface on which the bottom of the bag can rest. As materials are placed into the bag, the base (110) would ordinary provide a resting surface, but in an embodiment, including the depicted bag storage and retrieval system (300), the bottom of the bag (200) does not reach the base. Without a support (110), the bottom of the bag (200) would hang suspended within the bin (102), and as materials are accumulated in the bag (200), they would weigh it down, stretching and stressing the bag, and increasing the likelihood of a slip or tear. The support (310) relieves some of this pressure by providing a resting surface for accumulated material in the bag (200).

(45) In the depicted embodiment, the disc is oriented such that the flat surface of the support (310) is generally parallel with the base (110) and opening (108). The diameter of the support (310) is generally sized and shaped such that a gap (312) exists between the outer ridge of the support (310) and the interior of the surface of the storage bin (102) and the gap (312) is wide enough to allow a bag (200) to pass through the gap (312). This arrangement is depicted in FIG. 4. In the embodiment of FIG. 4, a roll of bags (402) is placed on the spindle (306) and unraveled in part, with the unraveled bags being threaded through the gap (312). The topmost bag (200) has an open end which is disposed on the bin (102) as described elsewhere herein.

(46) The spool of bags (402) may include, in an embodiment, a hollow tube at the middle of the spool through which spindle (306) is inserted, similar to bathroom tissue in a residential building. When the bag (200) is to be discarded, the bag (200) is removed from the bin (102) and sealed, such as by tying, zip tie, or other sealing system, and lifted out of the storage container (102). The roll of bags (402) initially includes a plurality of bags (200) connected to each other from bottom to top along a perforated edge (404). When the bag (200) in use is removed, the perforation (404) is torn, allowing the next bag in the spool (402) to be pulled from the container (102) and opened. By pulling on the top bag (200), the spool (402) will rotate about the spindle (306), allowing the next bag to pass through the gap (312) between the disc (310) and the inner wall of the container (102). In this fashion each bag (200) in the spool (402) may be used consecutively.

(47) The bin (102) may be used independently or in a storage system, and may include further elements not depicted in the Figures. By way of example and not limitation, the bin (102) may include a system for attaching or hanging the bin (102) on equipment, such as a wall, table, gurney, bed, vehicle, chair, or other fixture or device. The bin (102) may also be sized and shaped for attaching to such equipment, such as by having a flat surface to reduce rolling.

(48) In an embodiment, the bin (102) and/or grommet (106) are used in conjunction with a medical procedure, examination, or treatment, and the bin (102) and/or grommet (106) are sterilized and/or sanitized prior to the commencement of the medical procedure, examination, or treatment. In an embodiment, a bag (200) is disposed over the rim (128) and the grommet (106) is attached to the bin (102) before materials are placed in the liner bag (200). Materials are then placed in the bag (200) through the opening (108) of the bin (102) and the opening (122) of the grommet (106). The grommet (106) is then removed from the bin (102) before the bag (200) is removed from the bin, and the grommet (106) is inserted into the bag (200) through the opening (108) in the bin (102) while the bag (200) is still in the bin (102). Then, the bag (200) containing the grommet (106) is removed from the bin (102).

(49) In an embodiment including a bag storage and dispensing system, such as the system depicted in FIGS. 3-4, after the bag (200) containing the grommet (106) is removed from the bin (102), another bag (200) is retrieved from the bag storage and dispensing system and disposed on the rim (128) as described elsewhere herein. A second grommet (106), or the cleaned and/or sterilized first grommet (106), is then attached to the bin (102).

(50) While the invention has been disclosed in connection with certain preferred embodiments, this should not be taken as a limitation to all of the provided details. Modifications and variations of the described embodiments may be made without departing from the spirit and scope of the invention, and other embodiments should be understood to be encompassed in the present disclosure as would be understood by those of ordinary skill in the art.
