The present specification relates generally to disposable pads and bags used in medical and surgical procedures for placement under both the patient and instruments and for the disposal of waste materials. More particularly, the present specification relates to an indicator integrated into a combined procedure drape and carrying bag unit.
Conventional disposable absorbent drapes or pads used in medical and surgical procedures are often comprised of a plurality of absorbent and impermeable material layers joined mechanically to produce a sterile mat of given geometry. These mats are placed upon medical carts to establish a sterile work platform upon which surgical, endoscopic and other medical instruments may be placed upon, beneath the patient procedure zone, to contain wastes emanating from the procedure due to gravitational flow from the patient's body, and on other such areas in the procedural region to allow for capture of waste or the establishment of a sterile work surface.
With regards to a conventional absorbent drape, once the procedure is complete, the equipment involved in the procedure, which is now contaminated, is removed from the area by medical personnel. The equipment may be placed in a separate container for transport or left exposed to the environment and carried to a decontamination/sterilization area for preparation in the next procedural use. The absorbent disposable drapes used in the procedure are gathered by medical personnel and placed in containers or receptacles for proper disposal of biohazard materials.
During removal of the equipment and drapes, medical personnel may be exposed to biohazard materials deposited on the equipment and drapes. Procedures are commonly employed to reduce the level of exposure, but movement or disposal of the equipment and drapes still involves the placement of the affected articles into separate containers and transport or disposal units, and still involves exposure of medical personnel to biohazard materials deposited thereon. A combined drape and carrying bag unit has been described in U.S. Pat. No. 8,042,688, assigned to the applicant of the present invention, to limit medical personnel exposure to waste materials, collect all used equipment, and eliminate the need for a separate container, and is hereby incorporated by reference in its entirety.
What is additionally needed in, and beneficial to, drape and carrying bag units is a means of informing medical personnel of the contents of the bag once it has been closed, without the need of re-opening or looking inside the bag. Therefore, what is needed is an integrated labeling or identifying means that would become visible only after the procedure has been completed and the drape and carrying bag unit has been changed to its carrying bag configuration. Such an identifying means would inform medical personnel if the bag contains biohazard waste, used medical and/or surgical instruments, or some other post-procedural byproduct.
The present specification is directed toward a device for identifying contents of a combined drape and carrying bag unit used in medical and surgical settings. In one embodiment, the specification discloses a device for identifying contents of a combined drape and carrying bag unit, comprising a drawstring contained within a drawstring casing, for use in medical and surgical settings, comprising an indicator fixedly attached to a portion of said drawstring, wherein said indicator is compressed and hidden in the drawstring casing while said unit is in a first, mat configuration and said indicator is deployed and exposed outside the drawstring casing when said unit is converted into a second, carrying bag configuration.
Optionally, the indicator is sewn to the drawstring. The indicator comprises at least one of a flag, label, tag, card, rectangle, square, circle, or oval. The indicator is rectangular in shape and measures between 3 and 6 inches in length by 2 and 4 inches in width. The unit is converted from the first, mat configuration into the second, carrying bag configuration by pulling the drawstring through at least one space in the drawstring casing. When the unit is in the first, mat configuration, the indicator is positioned along the drawstring approximately 20-60 cm from the at least one space. When the unit is in the first, mat configuration, the indicator is positioned along the drawstring approximately 40 cm from the at least one space. The indicator contains preprinted information, a barcode for scanning, space for inscription of information by medical personnel, or any combination of the above.
In another embodiment, the present specification discloses a system for identifying contents of a combined drape and carrying bag unit used in medical and surgical settings, comprising a combined drape and bag carrying unit convertible from a first, mat configuration to a second, carrying bag configuration, said unit comprising a centrally positioned, generally rectangular shaped portion for receiving an instrument, a drawstring casing along the periphery of said unit with a continuous drawstring disposed therein, and at least two drawstring access openings positioned along said drawstring casing, thereby exposing a portion of said drawstring to medical personnel and an indicator fixedly attached to said drawstring along a particular length of said drawstring, said indicator is contained within said drawstring casing while said combined drape and bag carrying unit is in said first configuration, such that conversion of said unit from said first configuration to said second configuration results in said indicator automatically becoming deployed and exposed from said drawstring casing through at least one of said drawstring access openings.
Optionally, the indicator is attached to said drawstring at a position between 20 and 60 cm along the drawstring from at least one of said drawstring access openings when said unit is in said first configuration. The indicator is attached to said drawstring at a position 40 cm along the drawstring from at least one of said drawstring access openings when said unit is in said first configuration. The indicator is sewn to the drawstring. The indicator comprises at least one of a flag, label, tag, card, rectangle, square, circle, or oval. The indicator is rectangular in shape and measures between 3 and 6 inches in length by 2 and 4 inches in width.
In another embodiment, the present specification discloses a device for identifying contents of a combined drape and carrying bag unit, comprising a drawstring contained within a drawstring casing, for use in medical and surgical settings, comprising a first indicator portion of said drawstring and a second portion of said drawstring, wherein said first indicator portion visually differentiates said first indicator portion from the second portion of the drawstring, wherein said first indicator portion is hidden in the drawstring casing while said unit is in a first, mat configuration and wherein said first indicator portion is deployed and exposed outside the drawstring casing when said unit is converted into a second, carrying bag configuration.
Optionally, the first indicator portion comprises a portion of the drawstring that is a different color from the second portion of the drawstring. The unit is converted from the first, mat configuration into the second, carrying bag configuration by pulling the drawstring through at least one space in the drawstring casing. When the unit is in the first, mat configuration, the first indicator portion is positioned along the drawstring approximately 20-60 cm from the at least one space. When the unit is in the first, mat configuration, the first indicator portion is positioned along the drawstring approximately 40 cm from the at least one space.
In another embodiment, the present specification discloses a method for deploying an indicator integrated with a combined drape and carrying bag unit used in medical and surgical settings, comprising laying out a combined drape and bag carrying unit convertible from a first, mat configuration to a second, carrying bag configuration, said unit comprising: a centrally positioned, generally rectangular shaped portion for the disposition of an instrument, a drawstring casing along the periphery of said unit with a continuous drawstring disposed therein, at least two drawstring access openings positioned along said drawstring casing, thereby exposing a portion of said drawstring to medical personnel, and an indicator fixedly attached to said drawstring along a particular length of said drawstring, said indicator contained within said drawstring casing while said combined drape and bag carrying unit is in said first configuration; and placing medical waste or used medical equipment in the centrally positioned, generally rectangular shaped portion; and pulling on portions of said drawstring exposed at said drawstring access openings, thereby converting said unit from said first configuration to said second configuration by gathering together said periphery of said unit and forming a bag and further thereby deploying and exposing said indicator by pulling said particular length of drawstring with attached indicator out of said drawstring casing.
These, and other embodiments, shall be further described in the Detailed Description in relation to the drawings.
These and other features and advantages of the present invention will be further appreciated, as they become better understood by reference to the detailed description when considered in connection with the accompanying drawings:
The present specification is directed toward an indicator to be used in combination with a combined drape and carrying bag unit, said unit for use as a sterile or non-sterile surface mat during medical and surgical procedures and conversion of same through operation of embodied features therein to a carrying bag for the containment of procedural equipment and post-procedural waste.
In one embodiment, the indicator is integrated with the drape and carrying bag unit and hidden while the unit is in the drape configuration and exposed once the unit is converted to the carrying bag configuration. In various embodiments, the indicator comprises a flag, label, tag, or card with space available for alphanumeric and/or barcode information. As would be clear to one experienced in the art, in other embodiments, the indicator could take any other form or shape not listed above that would be easy for medical personnel to locate and read. In one embodiment, the indicator has preprinted information thereupon. In another embodiment, the indicator is blank and allows for inscription of identifying information by medical personnel. In yet another embodiment, the indicator includes both preprinted information and space for the inscription of additional information. The information included on the indicator informs medical personnel of the contents of the unit when in the carrying bag configuration, obviating the need for medical personnel to re-open the bag and visually inspect the contents, thereby limiting exposure to biohazard waste.
As described in U.S. Pat. No. 8,042,688, which is incorporated herein by reference in its entirety, the drape and carrying bag unit comprises a singular sheet or plurality of joined or attached sheets of pliable materials, both permeable and impermeable, of a size to define a mat to accommodate a working medical procedural area thereon, upon which may be placed in single or combination, medical equipment and biomaterials extracted from a patient. In one embodiment, the mat is of size to accommodate a patient's procedural volume thereon. In various embodiments, the mat is also suitable for use as a sterile or non-sterile procedural mat, medical cart mat, prep area mat, or the like. A drawstring casing extends about the periphery of the drape and has a plurality of openings therein. A drawstring is received in the drawstring casing and is of size to extend about the periphery of the drape when it defines a mat. The drawstring is slidably received in the drawstring casing so that when portions of the drawstring are pulled out of the drawstring casing through the openings, the periphery of the drape forms gathers adjacent the casing to permit the periphery to reduce in size and form a carrying bag.
In one embodiment, the drape has a generally rectangular periphery defined by two generally parallel side edges and two generally parallel end edges, the side edges being longer than and generally perpendicular to the end edges. The drawstring casing includes, but is not limited to, two openings positioned proximate the midpoints of those portions of the casing which extend along the end edges.
When portions of the drawstring are pulled out of the two openings and such drawstring portions are secured together adjacent the openings, a handle portion is formed. The handle portion is comprised of the drawstring casing, those portions of the drape adjacent the drawstring casing and those portions of the drawstring pulled out of the openings. In one embodiment, the indicator of the present specification is fixedly connected to the drawstring. The indicator is affixed to a specific segment of the drawstring such that, when the drape and carrying bag unit is in its drape or mat configuration, the indicator is positioned within the drawstring casing and is not visible. In another embodiment, the indicator is in the form of a differently colored portion of the drawstring itself, including a differently colored portion of the drawstring, a highlighted portion of the drawstring, a printed on portion of the drawstring, or some otherwise physically modified portion of the drawstring to create the desired indicator.
When a medical professional pulls on the drawstrings at the openings and the unit converts to the carrying bag configuration, the section of drawstring with the indicator attached becomes exposed and the indicator is deployed. In one embodiment, the indicator is folded or rolled to minimize area and unfolds or unfurls once it comes out of the drawstring casing.
The present invention is directed toward multiple embodiments. The following disclosure is provided in order to enable a person having ordinary skill in the art to practice the invention. Language used in this specification should not be interpreted as a general disavowal of any one specific embodiment or used to limit the claims beyond the meaning of the terms used therein. The general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the invention. Also, the terminology and phraseology used is for the purpose of describing exemplary embodiments and should not be considered limiting. Thus, the present specification is to be accorded the widest scope encompassing numerous alternatives, modifications and equivalents consistent with the principles and features disclosed. For purpose of clarity, details relating to technical material that is known in the technical fields related to the invention have not been described in detail so as not to unnecessarily obscure the present invention.
In one embodiment, a centrally located absorbent mat 130 is embedded within the unit 100, having a generally rectangular shape defined by two generally parallel end edges 140, 145 and two generally parallel side edges 150, 155. The unit also includes two creases 160, 165, about which draping sections 170, 175 are folded and hang down from the sides of a procedure table.
A drawstring casing or annulus 103 extends around the periphery of the drape and carrying bag unit 100. A continuous drawstring 193 is positioned within the drawstring casing 103. In one embodiment, two drawstring access openings 180, 185 or are positioned proximate the center of each side edge 115, 120. In another embodiment (not shown), the drawstring access openings are positioned proximate the center of each end edge. A portion of drawstring 193 is exposed and accessible to medical personnel at each of these two openings 180, 185. Simultaneously pulling on each exposed portion of drawstring 193 causes the side edges 115, 120, end edges 105, 110, and angled corner edges 117, 119 to be drawn and cinched together, resulting in a change in shape of the unit 100 from the drape or mat configuration to the carrying bag configuration. Any instruments, biohazard waste, or other objects lying on the unit at the time of cinching become enclosed within the carrying bag for transfer or disposal.
In one embodiment, an indicator is fixedly attached to a portion of the drawstring proximate one of the drawstring access openings. The indicator and drawstring are slidably movable within the drawstring casing. As the drawstring is pulled, the attached indicator will be pulled along with it.
In one embodiment, the indicator is folded or rolled to minimize its size and more easily fit within the drawstring casing 203. As the drawstring 293 is pulled, the indicator pulls along with it and exits the drawstring casing 203 at the drawstring access opening 280, becoming fully deployed. Deployment involves unfolding, decompressing, or unfurling of the indicator.
At step 425, a medical professional reads or labels indicator to determine contents of bag. In one embodiment, the medical professional scans a barcode on the indicator to determine and log the contents of the bag. If the bag contains medical or surgical instrument as in step 430, the instrument is properly removed for recycling at step 435. In one embodiment, recycling of the instrument(s) includes cleaning, sterilizing, and repackaging/labeling of the instrument for future use. Once the instrument has been removed, or, if the bag initially did not contain any instruments, the bag only contains biohazard waste as in step 440.
In one embodiment, the bag containing only biohazard waste is properly disposed of in step 445. In another embodiment, in step 450, the bag is opened, allowing drawstring and indicator to feed back into the drawstring casing, and the medical equipment is accessed and then properly cleaned, sterilized, and packaged for repeat use. The drape and carrying bag unit is disposed of 455.
It should be appreciated that, while the drape and carrying bag is shown as an octagonal shape, it can be of any shape that includes a central mat area with side portions extending therefrom and that is configured to adopt a bag shape upon constriction of a drawstring extending around the periphery of the central mat and side portions.
An indicator is then attached to the drawstring by placing 515 the indicator, such as a flag or tag, in physical contact with a portion of the drawstring at a location that is sufficiently close to the access point such that, upon pulling the drawstring through the access point, it causes the indicator to be pulled out of the drawstring casing through the access point but not so close as to be visible to a user when the drape and carrying bag is in a mat, or flat, configuration. In one embodiment, the indicator is placed at a point that is 20-60 cm (including all integer and fractional increments therein), and preferably 40 cm, along the drawstring from a drawstring access opening, when the drape and carrying bag unit is in the mat configuration.
After the indicator is placed in the appropriate physical location 515, the indicator is attached to the drawstring 520. The indicator may be attached to the drawstring by folding the indicator around the drawstring and attaching to the indicator to itself, sewing the indicator to the drawstring or to itself (which is wrapped around the drawstring), ultrasonic welding the indicator to the drawstring or to itself (which is wrapped around the drawstring), chemically adhering the indicator to the drawstring or to itself (which is wrapped around the drawstring), thermal/melting the indicator to the drawstring or to itself (which is wrapped around the drawstring), or heat tubing the indicator to the drawstring or to itself (which is wrapped around the drawstring).
After the indicator is attached 515, the edges of the material are folded over the drawstring, and the edges are attached to the body of the material, to thereby create a drawstring casing 525. In one embodiment, to minimize the likelihood of the indicator being improperly sewn to the material in the process of creating the drawstring casing, the edges of the drawstring casing may be attached and, before attaching the portion of the drawstring casing where the indicator and drawstring reside, the indicator and drawstring may be temporarily repositioned while the drawstring casing is formed. Once formed, the indicator and drawstring are then repositioned into the appropriate location. In one embodiment, the drawstring casing if formed by sewing, ultrasonic welding, chemical adherence, thermal/melting, or heat tubing.
Where the indicator is in the form of a differently colored portion of the drawstring itself, after the drawstring is placed in the appropriate position 510, an appropriate location for the indicator is identified 515 and the drawstring is colored, highlighted, printed on, or otherwise physically modified to create the desired indicator 520.
The above examples are merely illustrative of the many applications of the system of the present invention. Although only a few embodiments of the present invention have been described herein, it should be understood that the present invention might be embodied in many other specific forms without departing from the spirit or scope of the invention. Therefore, the present examples and embodiments are to be considered as illustrative and not restrictive, and the invention may be modified within the scope of the appended claims.
