BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to operating room sterilization equipment and methods, and in particular, to an improved mobile apparatus and method to sterilize one or more surgical trays, along with a dedicated integrable transfer and storage system.
2. Description of Related Art
A variety of instruments and supplies are required during modern operations. These are typically stored and sterilized in one or more wrapped trays. For example, an average knee replacement operation requires approximately twelve trays containing the instruments and supplies needed for this operation.
Traditionally, sterilization procedure has involved the steps of washing each tray, loading instruments and supplies into the tray, and then wrapping each tray individually within a protective wrap, frequently a 54-inch by 54-inch sterilizable linen or blue wrap. If a tray were to have sharp corners or protuberances, these would have to be padded with a towel or foam blocks to avoid tearing the protective wrap. The one or more loaded and wrapped trays would then be placed onto the shelves of a cart, and the cart inserted into an autoclave for sterilization.
Within the autoclave, the cart loaded with one or more trays generally would be sterilized at 270 degrees Fahrenheit for four to ten minutes, and then removed from the autoclave. The tray or trays are required to dry for up to 60 minutes before handling.
The tray or trays are put away into storage until needed. When required, each tray would be transported to the operating room, inspected and unwrapped as its contents were needed for the procedure being performed. Each tray would bear a chemical indicator that would read the sterilization status of a tray. Each chemical indicator would also then have to be inspected.
It would take in the vicinity of ten to fifteen minutes to inspect each tray and its chemical indicator and to unwrap the trays. Sterile 54-inch by 54-inch wraps cost approximately $3.00 per tray, so that a cart bearing twelve trays would require about $36.00 in sterile wraps. In addition, the cost of twelve chemical indicators and protective padding would have to be added to the sterilization costs for the cart.
If a wrap were found to have been torn or breached, the contents of the tray to which that wrap had been applied would have to be considered non-sterile. In this event, the autoclaving procedure would have to be repeated (which takes about one hour and 45 minutes), or in the alternative, an emergency “flash autoclave” would have to be performed. A flash autoclave involves sterilizing a tray in an autoclave for about ten minutes. A flash autoclave is not as thorough a sterilization as the full procedure, and carries greater risks. Therefore, when a sterile wrap was discovered to have been torn or breached in the operating room while a procedure was underway, the surgeon would be faced with the undesirable choice of having to wait one hour and 45 minutes for a full autoclave sterilization, or order a flash autoclave if such a delay were unacceptable. Any delay could be potentially damaging to the patient, because time spent under anesthesia is best minimized.
Mobile Apparatus and Method to Sterilize Surgical Trays, U.S. Pat. No. 8,454,901 (Snyder) teaches a mobile apparatus and method to sterilize surgical trays which does not require the use of protective wraps, which reduces the number of chemical indicators required, and which contemplates the capacity to transport the sterilization apparatus to and from an autoclave, a storage area, or an operating room. This apparatus and method, however, while clearly superior to more traditional sterilization processes, still requires the use of a large industrial autoclave, and provides adequate no means for readily moving the apparatus between a sterilization location, a storage area, and an operating room.
The large industrial autoclaves used in hospitals are very expensive pieces of equipment, costing between $100,000.00 and $250,000.00 each. A big hospital typically may have between four and six such autoclaves, which constitute a substantial capital investment. Moreover, there are other significant operational costs associated with these autoclaves, including labor and material costs associated with the preparation for each sterilization, as well as ongoing maintenance and repair. The failure of even a single autoclave can result in not only additional economic outlays, but in potentially adverse consequences for patient care.
By eliminating the need for separate industrial-sized autoclaves, a medical facility could enjoy substantial capital and operational savings, and patient care could be enhanced and rendered more reliable. Storage space could be better utilized and more sterilizations could be carried out in less time, particularly if a compact autoclave apparatus were to be integrated with a means of easily and securely transporting it from one location to another and with a means of maximizing the ease and efficiency with which such an apparatus were to be stored.
BRIEF SUMMARY OF THE INVENTION
The present invention, an improved mobile apparatus and method to sterilize surgical trays, comprises a cabinet, at least one shelf sized to support one or more surgical trays, and removable, autoclavable wheels. Surgical trays are placed within the cabinet, the cabinet doors are closed, and to sterilize the trays, an effective quantity of a sterilization agent is introduced into the cabinet via one or more input couplers attached to the cabinet for a time sufficient to carry out the sterilization of the interior of the cabinet and any contents thereof. The sterilization agent may then be removed from the cabinet via one or more vacuum outlet couplers. The cabinet doors are not unsealed until the cabinet is in the operating room, ready for use. At that point the doors may be opened, any trays removed, and the sterilized contents of the trays used.
Chemical indicators and a locator card may be used to verify the sterilization status and autoclave history of the cabinet and its contents. Maintenance steps include periodically replacing the filters and door gasket. In at least one embodiment of the invention, the cabinet may be configured readily into a surgical back table. RF location software and hardware may be incorporated into the apparatus as well.
The invention further comprises and integrable transfer and storage system that includes a transfer cart to facilitate moving the cabinet between storage areas, operating rooms, and other locations within a medical facility, as well as a modular lift device allowing the cabinets to be stacked vertically for maximum storage efficiency. A transfer cart may also be stored within the lift device.

DETAILED DESCRIPTION OF THE INVENTION
The present invention is an improvement over, and may incorporate all or any combination of features found in U.S. Pat. No. 8,454,901 B1 (Snyder). The invention that is the subject of the instant application comprises a Cabinet 2, integrable with a Transfer Cart 81 and Lift Device 100, having cabinet access means for opening and closing the Cabinet 2, cabinet securing means to maintain a Cabinet 2 in a closed state, as well as at least one Shelf 66 capable of admitting at least one surgical tray. The term ‘cabinet access means’ as utilized herein is intended to include any structure that can be employed to carry out the function of opening and closing a Cabinet 2, and the term ‘cabinet securing means’ is intended to include any structure that can be employed to carry out the function of fastening to ensure that a Cabinet 2 remains in a closed state, whether or not such a structure is recited with particularity herein.
A Cabinet 2, which may be made from stainless steel, other metal or synthetic materials, or indeed, any other suitable materials or combinations of any such suitable materials whatsoever, may have one or more filterable vents allowing air to pass between the exterior to the interior of the Cabinet 2, said vents typically located in the vicinity of a Cabinet Roof 4, a Cabinet Bottom 60, or both. After at least one standard surgical tray has been loaded into a Cabinet 2 and the Cabinet 2 has been closed and sealed, steam, ethylene oxide gas (ETO) or any other appropriate sterilization agent is introduced into the Cabinet 2 through at least one Input Coupler 32 in an effective amount for a time sufficient to achieve sterilization of the interior of the Cabinet 2 and its contents.
A sterilization agent thereafter may be evacuated from a Cabinet 2 through at least one vacuum Outlet Coupler 62, and the Cabinet 2 then may transferred a storage area until needed or otherwise be taken to an operating room where the Cabinet 2 may be reopened and unsealed, and any surgical tray therein removed and used as required, obviating the necessity of protective wraps and redundant chemical indicators, as well as the necessity of an industrial autoclave into which the entire Cabinet 2 must be inserted in order to carry out sterilization of the interior of the Cabinet 2 and its contents.
The Cabinet 2 has been designed to be integrated with a Transfer Cart 81 and transported via said Transfer Cart 81 between a given sterilization location, a storage location, and an operating room. A Transfer Cart 81 itself is designed to be secured to an industrial autoclave for purposes of transferring a Cabinet 2 from the Transport Cart 81 into an industrial autoclave, if desired, for sterilization of an entire Cabinet 2 and its contents. The Cabinet 2 and the Transfer Cart 81 are meant to integrate with a dedicated modular, expandable Lift Device 100 that allows vertical stacking of Cabinets 2 for efficient storage and provides a means of storage for at least one Transfer Cart 81 as well.
FIG. 1 is a front left top isometric view of a clamshell-style embodiment of a Cabinet 2 in a closed state. In this embodiment, the Cabinet 2 comprises a Left Cabinet Portion 2a and a Right Cabinet Portion 2b. Clamshell Hinges 46 allow the Cabinet 2 to be opened and reopened to access the interior of the Cabinet 2 by pivotally rotating the Left Cabinet Portion 2a and the Right Cabinet Portion 2b independently away from one another, and closed and reclosed by pivotally rotating said portions towards one another. The Left Cabinet Portion 2a and the Right Cabinet Portion 2b may secured together in the closed state by any cabinet securing means, which will typically be mechanical in nature, such as the Clamshell Closures 18 illustrated in FIG. 1, each such Clamshell Closure 18 comprising a Clamshell Closure Female Member 20 and a Clamshell Closure Male Member 22.
In this particular clamshell-style embodiment, a Cabinet Roof 4 is formed by a Left Cabinet Roof 4a and a Right Cabinet Roof 4b adjacent to one another when the clamshell embodiment of the Cabinet 2 is in a closed state. One or more Filter Well Vented Doors 10, each of which may include a Filter Well Vented Door Handle 14, may be located on both the Left Cabinet Roof 4a and the Right Cabinet Roof 4b. Every Filter Well Vented Door 10 has a plurality of Vent Holes 11. Each Filter Well Vented Door 10 may be removably attached to the Cabinet Roof 4 or Cabinet Floor 16 (see FIG. 8) by means of a Filter Well Vented Door Hinge 12, and each Filter Well Vented Door 10 may employ a Filter Well Vented Door Handle 14 to facilitate the opening and closing of the Filter Well Vented Door 10.
A Filter Well Vented Door 10 may be secured in a closed position by locking means, such as the Filter Well Vent Door Cam-Lock 24 pictured in the embodiment in FIG. 1. A Filter Well Vent Door Cam-Lock 24 typically may be comprised of one or more Filter Well Vent Door Cam-Lock Female Elements 27 and one or more Filter Well Vent Door Cam-Lock Male Elements 25. Security integrity means, typically mechanical in nature, such as the Closure Integrity Lock 26 illustrated, may be used to ensure the integrity of any locking means, such as a Filter Well Vent Door Cam-Lock 24, so that said cabinet securing means do not become disengaged or otherwise fail during the course of sterilization. The term ‘security integrity means’ is intended to include any structure that can be employed to carry out the function of ensuring or enhancing the integrity of any other securing means or locking means, whether or not such a structure is recited with particularity herein. A Chemical Indicator Sticker 28 may be applied to any Closure Integrity Lock 26 to help to ascertain readily the sterilization status of the Cabinet 2.
As illustrated in the embodiment present in FIG. 1, a Pressure Gauge 34 and a Temperature Gauge 35 may be incorporated into the Cabinet 2 to allow monitoring of the temperature and pressure on the inside of the Cabinet 2 before, during, and after sterilization. A Chemical Indicator Card Holder 36 in which a chemical indicator card (not illustrated) may be inserted to further ascertain the sterilization status of the Cabinet 2 also may be positioned on the outside of the Cabinet 2. A Serial/Lot Code Data Plate 38 can be attached to the Cabinet 2 for identifying the Cabinet 2, and a Locator Card Holder 40 may be included on the Cabinet 2 to accept a locator card (not illustrated) for recording the history of the Cabinet 2, e.g., the date and time that the Cabinet 2 has undergone autoclave. FDA Certification Placards 30 may provide information required by federal law and regulations concerning requirements and recommendations respecting the Cabinet 2 and its operation.
Each Cabinet 2 may have a plurality of removable, autoclavable Cabinet Wheels 48 to facilitate its movement between a dedicated Transfer Cart 81 with one or more Transfer Cart Connecting Rails 86 and a designated Lift Device 100 with one or more Lift Rails 109. A Cabinet Wheel 48, together with a Long Safety Retention Tab 50 and a Short Safety Retention Tab with Slot 51, may be attached to a Cabinet 2 by screws or by any other suitable attachment means. The Long Safety Retention Tab 50 associated with a Cabinet Wheel 48 serves to keep the Cabinet Wheel 48 on and guided by a Transfer Cart Connecting Rail 86, a Lift Rail 109, or a rail used in an industrial autoclave, as well as to provide a structure with which a Cabinet Safety Lock 95 may engage to secure a Cabinet 2 to a Transfer Cart 81. The Short Safety Retention Tab with Slot 51 associated with a Cabinet Wheel 48 provides a structure with which a Cabinet Safety Pin 85 may engage to secure a Cabinet 2 to a Transfer Cart 81.
FIG. 1 further reflects a Cabinet Handle 42 on a Cabinet Right Side 6. A Cabinet Handle 42 may be positioned on either side of the Cabinet 2 to allow the Cabinet 2 to be pulled or otherwise manipulated into a desired position. The Cabinet may also have a hinged deployable External Cabinet Shelf 44 for the placement of a biological challenge pack for orthopedic prostheses and similar items, which may be sterilized within the Cabinet 2. The External Cabinet Shelf 44 may be locked into place and unlocked by means of an External Cabinet Shelf Lock 45.

The Cabinet 2 as described allows for an improved method of sterilization of surgical trays. First, gaskets may be examined and replaced as necessary or desired. In the case of a clamshell-style embodiment of a Cabinet 2, any Clamshell Gaskets 64 may be inspected and replaced if necessary or desired. With respect to door-style embodiments of a Cabinet 2, Cabinet Door Gaskets 130 may be replaced as necessary or desired, as well as any gasket between a Left Cabinet Door 132 and a Right Cabinet Door 134. Filter Well Vented Door Gaskets may also be inspected and replaced as necessary or desired.
Next, a Cabinet 2 is prepared for sterilization by installing any necessary or desired Filters 56 (Filters 56 may, but need not, be used if sterilization is to be conducted with Ethylene Oxide (ETO) gas). The installation of Filters 56 is accomplished, with respect to each Filter Well Vent Door 10, by disengaging each Filter Well Vent Door Cam-Lock 24 or other locking means so as to unlock the Filter Well Vent Door 10, opening each Filter Well Vent Door 10, inserting a Filter 56 within each Filter Well 58, closing each Filter Well Vent Door 10, engaging each locking means, such as a Filter Well Vent Door Cam-Lock 24, and installing security integrity means, such as a Closure Integrity Lock 28.
At this point, a Cabinet 2 maybe closed and secured until it is time to proceed with sterilization. In the case of a clamshell version of a Cabinet 2, this may accomplished by pivoting a Left Cabinet Portion and a Right Cabinet Portion towards one another, then engaging the Clamshell Closure 18 or other cabinet securing means to hold fast the Cabinet 2. In the case of a door embodiment, the Cabinet Door(s) 120 is/are closed and the Cabinet Door Closure 124 or other cabinet securing means engaged. When it is time for sterilization, the Cabinet 2 may again be opened as described above.
When it is time for sterilization, surgical trays and their respective contents are then inserted into the Cabinet 2 as prepared above and onto Shelves 66 that have already been installed within the Cabinet 2 at the desired level(s). Chemical Indicator Stickers 28 may at this point be inserted within the interior of the Cabinet B, which is then closed as described above, and the Clamshell Closure 18, Cabinet Door Closure 124, or other cabinet securing means engaged. At this point, Closure Integrity Locks 26 or other security integrity means may be engaged with respect to the Clamshell Closure 18, Cabinet Door Closure 124, or other cabinet securing means, as applicable.
One or more supply lines for a sterilization agent is/are then attached to one or more Inlet Couplers 34, and one or more vacuum lines are attached to one or more Outlet Couplers 62. The sterilization agent, which may be steam, ETO, or another appropriate substance, is then introduced into the Cabinet 2 through the one or more Inlet Coupler(s) 34 in an effective amount for a period of time sufficient to achieve sterilization of the interior of the Cabinet 2 and its contents, following which said sterilization agent may be extracted from the Cabinet 2 via one or more Outlet Couplers 62. The supply and vacuum lines are then removed from the one or more Inlet Couplers 34 and the one or more Outlet Couplers 62, respectively. The contents of the Cabinet 2 are now sterilized and ready for use. The Cabinet 2 may be taken to storage until it is time to use the sterilized surgical tray or trays and their contents.
