The present invention relates in general to the field of medical procedures. More particularly, the present invention relates to drapes used during medical procedures to improve sterile conditions. Specifically, a preferred embodiment of the present invention relates to a drape that is used to maintain sterility about a surgical back table holding medical instruments prior to a medical procedure.
In the operating room, a back table is an area where there is major risk of contamination. Traditionally, the various pieces of medical equipment that will be utilized during the medical procedure are placed onto the back table prior to the surgery. More specifically, a sterile cover is applied to the back table, and then the medical equipment is placed upon the cover. Because the bulk of these pieces of medical equipment will come into direct contact with a patient, it is imperative that all of the equipment remains sterile prior to the surgical procedure.
As a result, contamination about a back table is a major problem during surgical procedures. Back tables can be contaminated in as little as 30 minutes when exposed to air in the operating room. In fact, The Journal of Bone and Joint Surgery has found that approximately 4% of back tables are contaminated after 30 minutes, 15% of back tables are contaminated after an hour, 22% of back tables are contaminated after two hours, and 30% are contaminated after four hours. Obviously, these contaminations can present significant health concerns to patients and significant costs to the hospital or medical facility.
As a result, current standard practice is that once the medical equipment is placed onto the back table, the back table must not be “left unobserved.” See 2017 AORN Guidelines for Perioperative Practice. Nurses usually refer to this as keeping the back table attended. Further, this has commonly been interpreted to mean that a member of the medical staff must stay with the back table and equipment lying thereupon to ensure that sterility about the table is maintained. Obviously, this results in additional costs to the hospital or medical facility in terms of human resources. Additionally, by requiring constant observance of the back table, it is impractical to prepare the back table, including installing the cover and organizing the medical equipment, far in advance of the surgery.
It should also be noted that even when a back table is attended, this does not protect the back table from contamination in the air, such as by dust, bacteria, air circulation, and the like.
U.S. Pat. No. 8,726,907 and Application Publication Nos. 2014/0251346 and 2015/0374442, all of which are incorporated herein by reference in their entirety, have introduced a number of different drapes used throughout the medical field to help avoid potential breaches in sterility. While many of the drapes shown in this patent and applications could be used to help maintain sterility about the back table, there is still a need to provide a drape that provides a sufficient alternative to having the back table under constant observation as suggested by the 2017 AORN Guidelines.
What is needed therefore is a drape system that can be used with a surgical back table to ensure that sterility is maintained about the back table and the instruments resting thereon without constant observation by a member of the medical staff. What is also needed is a drape system that provides a visual indicator that allows medical practitioners to quickly and easily determine whether a prepared back table, including a back table drape has been tampered with, which could result in a loss of sterility. What is further needed is a drape system that allows the back table to be assembled and sterility to be maintained prior to the surgical procedure. What is also needed is a back table drape that is transparent, which allows a user to visually inspect the contents of the back table.
By way of summary, the present invention is directed to a drape system. A primary object of the invention is to provide a drape system that is used with a surgical table including a sterile drape and at least one securement device. The surgical table is supported by a plurality of legs with an underside and a top surface with a perimeter. The top surface is used to support a plurality of surgical instruments.
Another object of the invention is to provide a sterile drape that may have a first edge, a second edge, a first end, a second end, a bottom side, a perforation, and an overlapping portion. In one embodiment, the perforation extends from the first end to the second end between the first side and the second side. The overlapping portion is located above the perforations.
Additionally, the sterile drape may include an area defined by a predetermined length and a predetermined width. The drape may also have a selectively separable portion extending a substantial portion of at least one of the predetermined length and the predetermined width. The selectively separable portion further includes a first peripheral edge and a second peripheral edge. These peripheral edges are initially in a sealed position but can be unsealed by applying opposing forces to the peripheral edges. Additionally, the selectively separable portion includes a first overlaying section which overlays the selectively separable portion when the sterile drape is in a sealed position.
Yet another object of the invention is to provide a securement device that is used to secure the sterile drape to the surgical table. Preferably, the securement device is configured to indicate when the sterile drape has been moved from the surgical table. This allows a user to ensure that sterility is maintained about the top surface and the plurality of surgical instruments.
For instance, in yet another aspect of this invention, the securement device is an adhesive sticker with a first side, a second side opposite the first side, a third side extending between the first side and the second side, and a fourth side extending between the first side and the second side and located opposite the third side. The adhesive sticker also has a perforation that extends from the first side to the second side. The perforation is configured to easily break when the adhesive sticker is pulled apart. In one embodiment, the third side of the adhesive sticker is attached to one of the first edge, the second edge, the first end, or the second end of the sterile drape and the fourth side is attached to one of the underside or one of the plurality of legs.
In another aspect of the invention, the system can additionally include one of a magnet and a weight that is rested on top of the sterile drape. The magnet may form a magnetic connection with the table. Both a magnet and a weight help to keep the sterile drape secured to the table.
In yet another aspect of the invention, the sterile drape may have at least one poly-tie. Each poly-tie has a first end permanently attached to the sterile drape, a second end with an adhesive, and a release liner covering the adhesive. When the poly-tie is used, the release liner can be removed to expose the adhesive and the second end is pulled away from the first end. The adhesive is then secured to the sterile drape to secure the sterile drape to the table. Once the second end is secured to the sterile drape, a third side of the adhesive sticker is attached to the second end of the poly-tie and the fourth side of the adhesive sticker is attached to the sterile drape. In this way, if the second end of the poly-tie is detached from the sterile drape, the adhesive sticker will break about the perforation to provide visual evidence that sterility about the table may have been compromised. Alternatively, the system can also include a buckle through which the poly-tie may be secured. The third side of the adhesive sticker is then attached to the poly-tie and the fourth side of the adhesive sticker is attached to the sterile drape.
In another aspect of the invention, the system may include a plurality of rubber bands and a plurality of hooks that are used to engage adjacent rubber bands. These rubber bands are wrapped around the perimeter, and a third side of the adhesive sticker is attached to one of the hooks, and the fourth side of the adhesive sticker is attached to the sterile drape. In this way, if the hook is disengaged from the rubber bands, the adhesive sticker will break about the perforation to provide visual evidence that sterility about the table may have been compromised.
In another aspect of the invention, the system may include a plurality of clips that releasably attach to the plurality of legs. In doing so, the clips secure the sterile drape to the plurality of legs. The third side of the adhesive sticker is then attached to the clip, and the fourth side of the adhesive sticker is attached to the sterile drape. In this way, if the clip is detached from the leg, the adhesive sticker will break about the perforation to provide visual evidence that sterility about the table may have been compromised.
In another aspect of the invention, the securement device includes a plurality of adhesive tabs located on the bottom side of the sterile drape and a plurality of release liners releasably attached to the adhesive tabs. When the sterile drape is ready to be used, the release liners are removed to expose the adhesive tabs, and the tabs are anchored to the top surface of the table. In the event that any of the adhesive tabs are not anchored to the top surface, it will be evident that sterility about the table may have been compromised. Alternatively, the adhesive tabs can be anchored to the perimeter. Additionally, the sterile drape may have a perforation that extends around the perimeter.
In yet another aspect of the invention, the securement device includes at least one strap with a first end, a second end, and a body located therebetween. The first end is attached to one of the plurality of legs, the body secures the sterile drape to the table, and the second end is attached to another one of the plurality of legs. The third side of the adhesive sticker is attached to one of the first end and the second end and the fourth side of the adhesive sticker is attached to one of the plurality of legs. In this way, if the end is detached from the leg, the adhesive sticker will break about the perforation to provide visual evidence that sterility about the table may have been compromised. Additionally, the strap could be reusable.
In another aspect of the invention, the securement device includes at least one strip of tape with a first end, a second end, and a body therebetween. The first end of the tape is attached to one of the plurality of legs, the body is secured to the sterile drape, and the second end of the tape is attached to another of the plurality of legs.
In accordance with another object of the invention, a method of maintaining sterility about a back table is provided. This method can include placing a sterile cover on a top surface of the back table. After the cover is placed, a plurality of sterile surgical instruments may be placed on the sterile cover. Next, a sterile drape is placed on top of the sterile surgical instruments. After the drape has been placed, a securement device is used to secure the sterile drape to the surgical table. The securement device is configured to indicate when the drape has been removed from the surgical table to ensure sterility is maintained about the top surface and the plurality of surgical instruments.
In accordance with another aspect of the invention, the method may include additional steps. For instance, an adhesive sticker that is the securement device can be provided. The adhesive sticker may include a first side, a second side, a third side, and a fourth side, with a perforation located between the third side and the fourth side. The third side of the adhesive sticker is then attached to one of a plurality of legs supporting the table, and the fourth side of the adhesive sticker is attached to the sterile drape. Once it is time to perform the surgical procedure, the adhesive sticker may be broken in half about the perforation by pulling the third side of the adhesive sticker away from the fourth side of the adhesive sticker.
These and other aspects and objects of the present invention will be better appreciated and understood when considered in conjunction with the following description and the accompanying drawings. It should be understood, however, that the following description, while indicating preferred embodiments of the present invention, is given by way of illustration and not of limitation. Many changes and modifications may be made within the scope of the present invention without departing from the spirit thereof, and the invention includes all such modifications.
A clear conception of the advantages and features constituting the present invention, and of the construction and operation of typical mechanisms provided with the present invention, will become more readily apparent by referring to the exemplary, and therefore non-limiting, embodiments illustrated in the drawings accompanying and forming a part of this specification, wherein like reference numerals designate the same elements in the several views, and in which:
In describing the preferred embodiment of the invention which is illustrated in the drawings, specific terminology will be resorted to for the sake of clarity. However, it is not intended that the invention be limited to the specific terms so selected and it is to be understood that each specific term includes all technical equivalents which operate in a similar manner to accomplish a similar purpose. For example, the word connected, attached, or terms similar thereto are often used. They are not limited to direct connection but include connection through other elements where such connection is recognized as being equivalent by those skilled in the art.
The present invention and the various features and advantageous details thereof are explained more fully with reference to the non-limiting embodiments described in detail in the following description.
The current invention is directed to a sterile drape for use with a surgical table that has a tamperproof feature that provides a visual indicator to help a user easily determine if sterility has been compromised about the table. The drape is a sterile cover that helps reduce the risk of contamination from airborne micro-organisms. The drape can be used over the top of a surgical back table that is positioned inside an operating room before an upcoming clinical procedure. These tables traditionally remain in a static condition (i.e. non-mobile table) when they are prepared. A surgical technician first places a sterile back table cover over the top surface of the surgical back table. Next, the surgical technician places sterile surgical tools and instruments on top of the cover to prepare for an upcoming clinical procedure.
Current AORN Guidelines for perioperative practice require that the sterile field is not subject to unrecognized contamination by personnel, vectors (e.g. insects), or breaks in the sterile technique, if left unobserved. The language relating to being “unobserved” has been interpreted to mean that once the back table has been prepared, a sterile field should not be left unattended. This means that an employee of the hospital must remain by the back table to ensure sterility is maintained. However, by introducing a tamperproof securement device to the drape, sterility can be maintained about the back table without having to rely on an employee to constantly observe the back table. In order for this to occur, airflow about the perimeter edges of the drape must not lift the edge of the drape.
A number of different securement devices could be used. For instance, the sterile drape could have built-in weights along the edges to prevent airflow from lifting the perimeter edges. Additionally, tamperproof stickers are applied to the drape and to the legs of the table or the underside of the table. In the event that the sticker is torn, it will be clear to individuals observing the table that sterility may have been breached.
Additionally, magnets could be used that form a magnetic connection with the table. Alternatively, in the event that the table is not made of a magnetic material, an adhesive-backed magnetic strip can be installed to the table. A magnet could then be placed on top of the magnetic strip in order to form a magnetic connection. Again, tamperproof stickers are applied to the drape and to the legs of the table or the underside of the table. In the event that the sticker is torn, it will be clear to individuals observing the table that sterility may have been breached.
Further still, poly-ties could be used with the sterile drape. For instance, poly-ties could be located at each of the four corners of the sterile drape. Each poly-tie is fastened to the drape, and tamperproof stickers are applied to the poly-tie and to the drape. Alternatively, a buckle or multiple buckles could be provided that the poly-tie can be inserted into. Also, a single long poly-tie can be wrapped around the perimeter of the table. Additionally, where a single long poly-tie is used, loops can be located around the perimeter to help guide where the poly-tie should be. Once installed, a tamperproof sticker is applied to the poly-tie and the drape or a portion of the table. If the sticker is torn, it will be clear that sterility may have been breached.
Alternatively still, a plurality of rubber bands and hooks could be used in combination to wrap around the table. Tamperproof stickers could then be fastened to the hooks and the drape or a portion of the table. If the sticker is torn, it will be clear that sterility may have been breached.
Also, clips may be used that are configured to snap over the legs of the back table. In use, the sterile drape would first be placed about the table. The sides of the drape are pulled downwardly and placed against each leg of the table before the clips are then snapped to secure the drape between the clip and the leg. Tamperproof stickers could then be fastened on one side to the clip and on the other side to one of the drape, the legs, or the underside of the table. Alternatively, the clips could be configured to be breakable when removed from the legs. This would allow a user to quickly and easily identify a potential breach of sterility where the clip is broken or the sticker is torn.
Further still, a plurality of adhesive tabs may be included on the underside of the drape, each of which is covered by a release liner. When unfolding the cover, the release liners are removed to expose the adhesive tabs. The adhesive tabs are then pressed against the table in order to anchor the drape to the table top. Alternatively, the adhesive tabs may be pressed against the perimeter of the table. A user can then visually inspect the adhesive tabs to see if any have been disengaged, which is evidence of a potential breach in sterility. Similarly, perforations can be utilized around the tabs, where the perforations are inspected for any evidence of tampering, which would result in potential breaches of sterility. The adhesive tabs could also be color coded with a top portion being a first color and a bottom portion being a second color. This would help to allow a user to quickly identify whether or not the tab has been broken.
Alternatively, a strap or straps could be used to secure the drape about the table. For instance, the strap could be situated such that a first end is secured to one of the table legs, and a second end is secured to the other of the table legs. For instance, the strap could form an “X” pattern or a “Z” pattern. The strap could be reusable and it could also be color coded. Once the strap is in place, tamperproof stickers could be applied to the strap and the legs or the table.
Additionally, a large zip-lock bag could be used that contains the sterile instruments. The bag could be configured to allow a user to visually understand whether the bag has remained sealed, for instance, using a bag with color changing technology that would result in a change of color once the bag is opened. Similarly, the bag could be vacuum-sealed such that it will be easy for a user to visually confirm whether the bag has remained sealed based on whether the bag is still vacuumed. In the event that the bag is not still vacuumed, it will be apparent that the seal has been broken, and that sterility might have been compromised. Also, a sterilized gas could similarly be applied to the drape and the surrounding components at any time to ensure sterility about the table and associated components.
It should also be noted that the drape or securement device could be moved or removed and later reapplied. By reapplying securement devices or applying new securement devices after the drape has either been moved or removed, risk of airflow about the table can be minimized, which in turn helps to maintain sterility.
Also, any of the drapes described above could also feature a time stamp. This could include pertinent information, including who prepared the back table, when it was prepared, what operation the table was prepared for, and identifying information about the patient. Alternatively still, an RF/ID tag could be installed onto the cover or drape, which would allow a smartphone, tablet, scanner, etc. to scan the label and capture date and time information once the drape is placed.
Any of the drapes described above could include a single or multiple sterile sheets of plastic. Alternatively, any of the drapes described above could include a single or multiple sterile sheets of patient drape material. Also, any of the drapes described above could include a single or multiple sterile sheets of fabric. Similarly, any combination of the above-discussed drapes could be used in combination with a perforation line. Additionally, a sterile dome bag and a sterile cinch bag could be used. Also, tamper evident tapes and labels could be used with any of the disclosed drape systems.
Turning to the figures, a drape system 50 with a sterile drape 64 and a securement device 80 for use with a table 52 is shown generally in
Specific embodiments of the present invention will now be further described by the following, non-limiting examples which will serve to illustrate various features of significance. The examples are intended merely to facilitate an understanding of ways in which the present invention may be practiced and to further enable those of skill in the art to practice the present invention. Accordingly, the examples should not be construed as limiting the scope of the present invention.
The sterile drape 64 includes a first edge 66, a second edge 68, a first end 70, and a second end 72. The first edge 66 and the second edge 68 form a predetermined length. The first end 70 and second end 72 form a predetermined width. The predetermined length and the predetermined width form an area. A perforation 151 is found in a bottom side 74 of the drape 64, with an overlapping portion 78 located above the perforation 151 at a selectively separable portion 146 covered by an overlaying section 154. Additionally, it should be noted that the sterile drape 64 is transparent. This is helpful because the back table 52 and its contents can remain visible by medical practitioners.
The overlapping portion 78 may form a “double Z” flap orientation, with a first peripheral edge 148 and a second peripheral edge 150, as shown in
Various securement devices 80 will now be described. Turning now to
In addition to using the adhesive sticker 82 to help confirm that sterility is maintained about the drape system 50, additional components can be used to keep the drape 64 secure to the table about the perimeter 60. For instance, turning to

Additionally, a single poly-tie 98 can be used to wrap around the entire perimeter 60 of the table 52. In such an embodiment, loops or hooks (not shown) can be included around the drape 64 or the perimeter 60 of the table 62. The poly-tie 98 can be guided into these loops or hooks so that it is easier to incrementally wrap the poly-tie 98 around the entire perimeter 60 of the table 62. The adhesive sticker 82 can then be applied as described above.

Additionally, a method of maintaining sterility about a surgical back table 52 is provided. This method includes initially placing a sterile cover 53 on a top surface 58 of the back table 52. A plurality of sterile surgical instruments 62 is then placed on the sterile cover 53. Once the surgical instruments 62 are appropriately located, a sterile drape 64 is placed on top of the sterile surgical instruments 62 and the sterile cover 53. A securement device 80 is then used to secure the sterile drape 64 to the surgical table 52. The securement device 80 is configured to indicate when the drape 64 has been removed from the surgical table 52 to ensure sterility is maintained about the top surface 58 and the plurality of surgical instruments 62. Also, an adhesive sticker 82 can be provided as the securement device 80, where the adhesive sticker 82 has a first side 84, a second side 86, a third side 88, a fourth side 90, and a perforation 92 that extends between the first side 84 and the second side 86. The third side 88 of the sticker 82 is then attached to one of a plurality of legs 54 supporting the table 52 and the fourth side 90 of the sticker 82 is attached to the sterile drape 64. In the event that the drape 64 is moved, the adhesive sticker 82 will break in half about the perforation 92 when the third side 88 is pulled away from the fourth side 90 of the adhesive sticker 82.
