Description

FIELD OF THE INVENTION

Exemplary embodiments of the present disclosure relate to a method and apparatus for loading and more particularly to a method and apparatus for loading and maintaining sterilized items. Exemplary embodiments of the present disclosure even more particularly relate to transporting and presenting collectively and individually sterilized items to a surgical field.

BACKGROUND OF THE INVENTION

Sterilization is a term referring to any process that eliminates (removes) or kills microbial life, including transmissible agents (such as fungi, bacteria, viruses, or spore forms) present on a surface, contained in a fluid, in medication, or in a compound such as biological culture media. Sterilization can be achieved by applying heat, chemicals, irradiation, high pressure, and filtration or combinations thereof.

In general, surgical instruments and medications that enter an already aseptic part of the body (such as the bloodstream, or penetrating the skin) must be sterilized to a high sterility assurance level. Examples of such instruments include scalpels, hypodermic needles and implantable medical devices (IMD), such as artificial pacemakers. This also includes all of the outer garments worn by the medical personnel, drapes used on or over the patient, and drapes used to divide the sterile portion of an operating room and the non-sterile portion of the operating room.

One method of sterilization involves passing a sterilizing agent, such as steam through a cabinet. For effective sterilization, steam needs to penetrate the cabinet load uniformly. Accordingly, the cabinet must not be overcrowded, and the lids of the bottles and containers must be left ajar. During the initial heating of the chamber, residual air must be removed. Indicators should be placed in the most difficult places for the steam to reach to ensure that steam actually penetrates there.

A filter is typically placed over the vent to keep particles or extraneous materials from entering the cabinet before, during or after the sterilizing process. Once the sterilizing process is completed the filter needs to be removed and inspected by medical professionals to verify the integrity of the sterilizing process was maintained. If it is discovered during the inspection that the filter did not remain intact, the sterilization process has to be repeated with a new filter.

DETAILED DESCRIPTION OF THE INVENTION

Prior to any surgical procedure, all of the items that will be used during the procedure should be properly sterilized. This includes all of the medical instruments, such as scalpels and needles as well as the outer garments worn by the medical professionals. Typically, each of the fabric items, such as garments and drapes, that are used during a medical procedure are individually sterilized and then wrapped in a sealed bag prior to the medical procedure. This allows the medical professionals to open and unwrap only the items that will be needed for a given procedure while maintaining the sterility of the unused items.

The individually sterilized items are typically kept in a cart, which is more commonly known as a case cart. The purpose of the case cart is twofold. First, the case cart maintains the individually sterilized items in a manner that will sufficiently ensure that the packaging and thus the sterile nature of each of the individually sterilized items is maintained. Second, the case cart provides accessibility and mobility for its contents, which can be wheeled from one area to another with relative ease.

Shown in FIG. 1 is an exemplary case cart 100. Case cart 100 includes a substantially flat top 102, push handles 104, shelf 106, doors 108, and wheels 110. Case cart 100 can be constructed out of any durable material that is strong enough to maintain its shape and form under significant weight and also able to be sterilized. Ideally, case cart 100 is constructed out of a steel or aluminum alloy or a combination thereof. It should be understood that case cart 100 is merely an exemplary embodiment of a case cart. Alternative exemplary embodiments of case cart 100 do not include an enclosed interior section, but offers an open midsection with one or multiple shelves.

Flat top 102 of case cart 100 provides a flat surface to maintain other items. Exemplary embodiments of the present disclosure provide that flat top 102 is rigid enough to maintain the weight of a sterilizing cabinet or other like sterilizing device or apparatus. Flat top 102 may also include a locking mechanism (not shown). The locking mechanism provides a means to removeably affix a sterilizing cabinet to case cart 100 on flat top 102. Exemplary embodiments of the locking mechanism include any means that would allow a sterilizing cabinet to be securely affixed to case cart 100 on flat top 102 such that a sterilizing cabinet only moves when case cart 100 moves. Exemplary embodiments of the locking mechanism include clamps, laches, slots, bolts, screws, and the like.

Push handles 104 of case cart 100 provide the means for a user to more easily push and pull case cart 100. In the embodiment shown in FIG. 1, push handles 104 are provided on opposite sides of case cart 100. Each of the push handles 104 span the width of case cart 100. It should be appreciated, that embodiments of push handles 104 include push handles 104 being located on all sides or only on one side of case cart 100 along with different configurations.

Case cart 100 also includes shelf or shelves 106. FIG. 1 depicts case cart 100 with only one shelf 106, however, exemplary embodiments of case cart 100 can include both numerous shelves 106 and zero shelves 106. Shelves 106 provide a stable location for maintaining individually sterilized items or non-sterile items. Exemplary embodiments of individually sterilized items include sterile garments, dividers or drapes that are typically used during a procedure or in an operating room. The individually sterilized items are each individually sterilized and then wrapped in a sealed wrapping that maintains the sterility of the item by preventing extraneous materials from coming into direct contact with the individually sterilized items. Non-sterile items include any type of instrument, tool, garment, apparatus, device, or thing that has not been sterilized as well as those that have not been sterilized and can be, will be or is typically used in or in conjunction with a procedure or in an operating room. Non-sterile surgical tape or gauze are non-limiting exemplary embodiments of non-sterile items.

In one exemplary embodiment, shelf or shelves 106 are flat and rigid enough to maintain the weight of a sterilizing cabinet or other like sterilizing device or apparatus. Shelf or shelves 106 may also include a locking mechanism (not shown). The locking mechanism provides a means to removeably affix a sterilizing cabinet to shelf or shelves 106. Exemplary embodiments of the locking mechanism include any means that would allow a sterilizing cabinet to be securely affixed to shelf or shelves 106 such that a sterilizing cabinet only moves when case cart 100 moves, for the case that shelf or shelves 106 are affixed to the body of case cart 100. For the case the shelf or shelves 106 are removable from case cart 100, the locking mechanism includes any means that allow a sterilizing cabinet to be securely affixed to shelf or shelves 106 such that the sterilizing cabinet only moves when shelf or shelves 106 move. Exemplary embodiments of the locking mechanism include clamps, laches, slots, bolts, screws, and the like. In a further exemplary embodiment, the sterilizing cabinet can be directly and removeably affixed to case cart 100 rather than on shelf or shelves 106, such as on the bottom or sides of case cart 100.

Also shown in FIG. 1 are door or doors 108. Door or doors 108 are able to open and close for access to the interior of case cart 100, which is typically in the midsection of case cart 100. Door or doors 108 are physically connected to case cart 100. Door or doors 108 can be attached through the use of a hinge or hinges which allows the doors to swing open. Door or doors 108 can also include a latch or lock for securely keeping door or doors 108 from opening when not desired. It should be appreciated that exemplary embodiments of door or doors 108 include any mechanism that allows for door or doors 108 to move from an open position to a closed position to provide access to the interior of case cart 100. Exemplary embodiments of case cart 100 provide that the interior of case cart 100 is of the shape and size such that an entire sterilizing cabinet can reside within the interior of case cart 100 and door or doors 108 are free to open and close without being obstructed should a sterilizing cabinet reside within the interior of case cart 100.

FIG. 1 also includes wheels 110 on case cart 100. Exemplary embodiments of wheels 110 provide a means for case cart 100 to be moved from one location to another. Embodiments of wheels 110 are configured to hold a significant amount of weight and are still able to freely rotate such that when a user pushes or pulls case cart 100, wheels 110 rotate in a direction of the user's actions. Embodiments of wheels 110 include the ability for wheels 110 to be selectively placed into a locked position wherein movement of wheels 110 is prohibited. Exemplary embodiments of case cart 100 include the four wheels 110 located at each corner of the bottom of case cart 100. However, it should be appreciated that alternative embodiments of case cart 100 include more or less than four wheels as well as different arrangements.

Exemplary embodiments of case cart 100 include numerous shapes and sizes. FIG. 2 depicts three such case carts. Shown in FIG. 2 is case cart 100, case cart 200, and case cart 202. As illustrated in FIG. 2, case cart 200 has almost all of the characteristics of case cart 100 except that it appears taller and includes a single door 204 and multiple shelves 206. Case cart 202 also has almost all of the characteristics of case cart 100 except that it too only includes a single door 208. It should be appreciated that case cart 100, case cart 200, and case cart 202 though they may appear differently, each of their elements (i.e., doors, wheels, shelves, and flat top portion) are configured to functionally perform the similar task of providing mobility and the ability to maintain individually sterilized items.

FIG. 3 depicts a perspective view of a cabinet or sterilizing cabinet 300. Exemplary embodiments of sterilizing cabinet 300 are able to collectively sterilize items that are placed within its interior. Exemplary embodiments of a sterilizing cabinet include any type of cabinet with the ability to be repeatedly subjected to a sterilizing process. Exemplary embodiments of a sterilizing cabinet further include the ability to use a filter or filters for passing a sterilizing agent into and out of the sterilizing cabinet. Shown in FIG. 3 is sterilizing cabinet 300 with door or doors 302, vents 304, primary filters 306, secondary filters 308, filter holders 310, and filter lock 312. Door or doors 302 are able to open and close for access to the interior of sterilizing cabinet 300. Door or doors 302 are physically connected to sterilizing cabinet frame 314. Door or doors 302 can be attached through the use of a hinge or hinges which allows the doors to swing open. Alternatively, door or doors 302 can be removable from sterilizing cabinet 300 through the use of clamps (not shown). It should be appreciated that exemplary embodiments of door or doors 302 include any mechanism that allows for door or doors 302 to move from an open position to a closed position to provide access to the interior of sterilizing cabinet 300. It should be appreciated that sterilizing cabinet 300 as depicted in FIG. 3 includes two doors 302, however, alternative exemplary embodiments of sterilizing cabinet 300 include as few as one door 302 as well as numerous doors 302.

Sterilizing cabinet 300 in the embodiment illustrated in FIG. 3 includes four vents 304. Exemplary embodiments of sterilizing cabinet 300 provide that sterilizing cabinet 300 may include one or more vents 304.

Vents 304 provide numerous small openings for the passage of a sterilizing agent, such as sterilizing steam. The small openings in vents 304 can be holes or slits. In an alternative embodiment, vents 304 are fenestrated.

Primary filter 306 in conjunction with filter holder 310 covers vent 304. Primary filter 306 with filter holder 310 forms a sealed interface with the adjacent portions of sterilizing cabinet 300 such that during the operation of a sterilizing cycle, any sterilizing steam that passes through the vents 304 must also pass through primary filter 306. Exemplary embodiments of primary filter 306 provide that primary filter 306 can be made of any porous material that (1) allows for the passage of sterilizing steam through sterilizing cabinet 300 and (2) prevents extraneous materials from passing through primary filter 306 and entering vent 304. Primary filter 306 is removable from sterilizing cabinet 300 and is typically replaced with a new filter following each sterilizing cycle.

Secondary filter 308 resides on top of primary filter 306 in filter holder 310. Secondary filter 308 covers primary filter 306 and forms a sealed interface with primary filter 306 in conjunction with filter holder 310 such that any sterilizing agent, such as sterilizing steam that passes through vent 304 must then pass through primary filter 306 and secondary filter 308. Secondary filter 308 can be made of any type of porous material that (1) allows for the passage of sterilizing steam from sterilizing cabinet 300 and primary filter 306 and (2) prevents extraneous materials from passing through secondary filter 308.

Exemplary embodiments of sterilizing cabinet 300 also include configurations wherein sterilizing cabinet 300 only includes a primary filter 306 and does not include the use of a secondary filter 308. Exemplary embodiments of this disclosure also provide for the embodiment that employs the use of a secondary filter 308 to form a sealed periphery with primary filter 306. In another exemplary embodiment the sealed interface between the primary filter 306 and the adjacent portion of either the sterilizing cabinet 300 is independent of an interface between secondary filter 308 and primary filter 306. In one exemplary embodiment, the primary filter 306 and the secondary filter 308 are coextensive. In another exemplary embodiment, primary filter 306 and secondary filter 308 have different filter properties. For instance, primary filter 306 and secondary filter 308 may filter different elements of the sterilizing agent, which exits sterilizing cabinet 300 during a sterilization cycle. In an alternative exemplary embodiment, primary filter 306 and secondary filter 308 have similar filter properties. Another exemplary embodiment provides that primary filter 306 and secondary filter 308 are different colors.

Sterilizing cabinet 300 also includes legs 314, which reside on the bottom of sterilizing cabinet 300. Legs 314 provide spacing between the surface which sterilizing cabinet 300 rests and the bottom primary filter 306, secondary filter 308 and filter holder 310. In an alternative exemplary embodiment, legs 314 provide spacing between the surface which sterilizing cabinet 300 rests and the bottom primary filter 306 and filter holder 310. In this alternative embodiment, sterilizing cabinet 300 does not contain secondary filter 308. It should be appreciated that legs 314 as depicted in FIG. 3 are only exemplary embodiments of the possible configuration of legs 314. In other exemplary embodiments, legs 314 include wheels (not shown) that allow for sterilizing cabinet 300 to roll on a surface. In this embodiment, legs 314 with wheels can include a locking mechanism that can selectively prevent the wheels from rotating when not desired. In yet another exemplary embodiment, legs 314 can include a flat bottom that allows sterilizing cabinet 300 to slide along a surface.

In another exemplary embodiment, legs 314 include a locking or attachment mechanism that provides a means for affixing sterilizing cabinet 300 to the top of a case cart. Exemplary locking or attachment mechanisms include slots, locks, clamps, clasps, notches, grooves, ramps and the like that would allow sterilizing cabinet 300 to removeably affixed to a surface.

Also shown in FIG. 3 is filter holder 310 for maintaining primary filter 306 and secondary filter 308. In another exemplary embodiment, filter holder 310 only maintains primary filter 306. Exemplary embodiments of filter holder 310 include a hinge which allows portions of filter holder 310 to swing open about the hinge such that primary filter 306 and secondary filter 308 can be removed or placed independent of one another. In other words, filter holder 310 allows for secondary filter 308 to be released and removed from filter holder 310 while simultaneously maintaining primary filter's 306 seal with sterilizing cabinet 300 over vent 304.

FIG. 4 is a perspective view of the construction of an alternative arrangement of sterilizing cabinet 300. As shown in FIG. 4, filter door 606 with clamps 608 attach around the frame of sterilizing cabinet 300. Primary filter 306 is placed on top of filter door 606 and attaches to sterilizing cabinet 300 at hooks 604. Secondary filter 308 is placed on top of primary filter 306 and also attaches to sterilizing cabinet 300 at hooks 604.

In other exemplary embodiments, device 500 may include a processor, a memory including computer program instructions, a display, a controller, and a transmitter/receiver for tracking the contents of device 500. In this embodiment, the memory or non-transitory computer-readable memory including computer program instructions which when executed on the processor of device 500 can cause device 500 to track when each item enters or exits sterilizing cabinet 300 and case cart 100. This tracking system can be performed any type of unit tracking system, such as through the use of barcode scanners. The display will be able to communicate with the other elements of device 500 and display on demand the list of items within sterilizing cabinet 300 and case cart 100 and when a particular item was removed. Additionally, the transmitter/receiver will be able to communicate via wired or wireless networks the same inventory information shown on the display. The controller will be able to communicate with the other elements of device 500 and will allow a user to access the inventory of device 500.

Device 500 in FIG. 5 in practice maintains individually sterilized items in case cart 100 and collectively sterilized items in sterilizing cabinet 300. Device 500 thus provides a means to simultaneously access individually sterilized items as wells as collectively sterilized items.

FIG. 6 presents a summary of the above teachings for loading device 500 in the form of a logic diagram. The logic diagram of FIG. 6 may be considered to illustrate the operation of a method. Block 652 presents loading one of an individually sterilized item or a non-sterile item into the cart, the cart comprising a top portion, and a plurality of wheels fixedly coupled to a bottom portion of the cart able to freely rotate and support the cart; and loading a sterilizing cabinet onto the cart, the sterilizing cabinet being removeably affixed to the cart and comprising an interior, the interior containing collectively sterilized items, the interior being sterilizable and resealable.
