DETAILED DESCRIPTION OF THE INVENTION WITH REFERENCE TO THE ACCOMPANYING FIGURES
The present invention as discussed hereinbefore relates to an improved surgical drape that includes a calibrated pouch component to collect and measure blood during post-partum hemorrhage.
Figure 1 illustrates a surgical drape comprising of a drape component; a fluid collection pouch component; a window component; one or more cavities; one or more fasteners; a stiffening mechanism; and a calibrated tape. The drape component has a main sheet portion (1) for wrapping around the abdomen of patient or onto a surgical table and may have the fenestration in proximity to the pouch for providing access to the posterior side of the abdomen on a patient undergoing surgery. The mainsheet portion is opaque and the inner portion of the main sheet is lined with absorbent material (16). The window component is attached to the mainsheet portion at the top and the sides. Both the top and the sides are sealed with heat seals and the bottom of the window being open. The fluid collection pouch (2) is inverted conical in shape with flattered top which is made of a front (3) and a rear panel (4) that is heat sealed together on the sides. The
base of the pouch is attached to the bottom of the mainsheet portion with the rear panel heat sealed to the posterior of the bottom of the mainsheet portion. The calibrated tape (8)/ transparent scale with markings are attached to the flattered apex of the front panel of the pouch with adhesives to measure volume of fluid in milliliters. One of the cavity is created by the heat seal over the window on the main sheet portion of the drape and the other cavity is created with one or more heat seals (9) that run parallel to each other along the width of the main sheet portion sealing a rectangular strip of the material that the main sheet portion of the drape is made of to the main sheet portion of the drape. In one aspect, the fastener is a tape/strip runs from left to right through the second/other cavity on the posterior side of mainsheet portion (1) of the drape at the bottom of the window with knots at both ends. The fasteners themselves may be designed to be capable of repeated fastening and unfastening events without failure. Examples of this design may include but are not limited to knot type fasteners, snaps, hook and loop, and clips. A pair of visual indicators is stamped on the front of the window on its sides with adhesives, the indicators being L and R stamps that indicate the left and right sides. The stiffening mechanism provided at the base of the front panel of the pouch is made of a stiffener (10) enclosed in a transparent cavity created by folding a part of the base of the front panel of the pouch and heat- sealing it on the sides and the bottom. The stiffener is made of a length of plastic cable with a backbone of metal to form a fenestration.
In accordance with another aspect, the drape configuration may vary based upon the type of surgical procedure toss" be performed and/or the preference of the surgical team. The pouch would be provided with a fenestration which would be opened to collect fluid. The top and at least a portion of the sides are open. Disposed upon at least one of the panels is plurality of spaced-apart fasteners that include Velcro straps, adhesive patches etc. to attach the drape onto the surgical table or to the patient. The fasteners are situated so as to secure the drape. This arrangement creates a series of alternating fastened regions and unfastened regions, in the otherwise open top. The number of fasteners and the distance between each is dependent upon the drape design and/or the pouch design itself. The alternating fastened and unfastened regions enable the surgical team to selectively choose whether or not to fasten any combination of fasteners independent of one another. The fasteners may be selected from any number of suitable alternatives. Alternatively, the fasteners may be designed for limited fastening and unfastening events. Examples of these include adhesives as well as adhesive tape (not shown). In some cases,
the adhesives may be designed for a single fastening only. The drape provides a sterile barrier between the patient and the surgical table.
The pouch may be stand-alone component that is attached to the drape just prior to the surgical procedure when the patient is being prepped. This would enable optimal placement of the pouch and repositioning of the pouch if desired by the surgical team. As such, the pouch may be attached to the drape by an adhesive, adhesive tape or other suitable alternative. The pouch may also be fastened to the drape during manufacture. In one possible construction, the adhesive is affixed to an outside surface of panel proximate to the top. The adhesive is contacted to the drape and subsequently adhering the pouch to the drape. To ensure proper fluid runoff, fenestration reinforcement material .(if provided) may be caused to overlap the interface of the drape and pouch. One alternative may to adhere the pouch directly to the fenestration reinforcement material. This is easily accomplished by affixing the adhesive to the surface of panel that contacts that fenestration reinforcement material. Referring to Figure 2 is the fluid collection pouch (2) affixed to a surgical drape selected so as to be appropriate to the type of surgery performed. The fluid collection pouch (2) comprises of a front panel (3) and a rear panel (4) joined along common side edges. The rear panel is attached to the drape in proximity to the fenestration and holds the pouch in place on the drape. The pouch in accordance with the present invention may be used to collect excess fluids that may escape from the operative site, thus minimizing contamination of the operating room by preventing the fluids from dripping on to the floor. Collection of patient fluid would also be beneficial to operating personnel in that it may help minimize the potential transfer of blood-borne pathogens. The pouch may also serve as a means to secure surgical tubes and lines in various configurations so that they remain in -position throughout the surgical procedure. Another use for the pouch described herein is for storage of surgical instruments and/or materials to be used in the surgical procedure. Such a pouch may be useful for any one individual or any combination of these purposes. The pouch would be attached to the bottom of the main sheet's embodiments.
The fluid collection pouch (2) may be constructed in a variety of ways, including as a bag or series of panels attached to one another. In this embodiment, front (3) and rear panels (4), each having a periphery is superimposed one over the other and sealed to one another along at least a portion of their peripheries. The superimposed and sealed panels together form the pouch. The
rear panel (4) may be constructed so as to be opaque, translucent or transparent in whole or in part. The materials for constructing the pouch are well known and understood by those skilled in the art. Some suitable materials for manufacturing the pouch include but are not limited to films and non-woven materials, in embodiments adapted to hold instruments for use in the intended procedure, it may be desirable for the front panel (3) to be transparent to better assist in the visual identification of the instruments contained within the pouch (2). As such a transparent film would be useful for this purpose.
The pouch is seen to have a top (5), a bottom- (6), and sides (7). The pouch may be of any shape desirable for the surgical procedure and may have more or less than two sides, a top and a bottom. In embodiments adapted to collect and retain fluids, the bottom is sealed along edge and the sides are sealed for some length "L" alongside edge. The length "L" is dependent upon the pouch design. Pouches designed to collect and retain significant amounts of fluid would be sealed a greater length "L" than those designed to collect and retain a lesser quantity of fluid. For example, in some embodiments the seal length "L" may extend for as much as about halfway up the side edges, in other embodiments the seal length may extend for as much as about seventy- five percent up the side edges. As stated, the seal length "L" may be any length deemed appropriate by those skilled in the art. Moreover, some embodiments of the pouch may configured to incorporate a drain and an appropriate fitting (not shown) to drain fluids collected. It should be understood that the existence of a drain would have a bearing upon the need for a specific seal length "L". As such, a shorter seal length "L" could be used even though larger quantities of fluids might be anticipated in the procedure because the drain would function to minimize the amount of fluid retained within the pouch.
Accompanying Figures 3, 5 and 7 are the front portion of the main sheet with absorbent material (16) for patient comfort. Figure 4 illustrates the back portion of the main sheet with absorbent material and one or more adhesive patches (1 1) to secure the drape to the surgical table. The pouch component has an open top end to which is attached one or more stiffeners (10) for attaching the poly lining (12) to hold the pouch open during use. Figure 6 illustrates the back portion of the main sheet with absorbent material and one or more tape/strip (13) to secure the drape to the surgical table. The tape/strip (13) is attached to the main sheet with heat seal (9). Patient's tucking area (14) lies between the fasteners. Figure 8 illustrates the back portion of the main sheet with absorbent material and one or more Velcro straps (15) to secure the drape to the
surgical table. Patient's tucking area (14) lies between the Velcro straps (15). Figures 9, 11 and 13 are the front portion of the main sheet without absorbent material for patient comfort. Figure 10 is the back portion of the main sheet without absorbent material and with one or more adhesive patches (11) to secure the drape to the surgical table. Further, it is provided with one or more stiffeners (10) for attaching the poly lining (12) to hold the pouch open during use. Figure 12 is the back portion of the main sheet without absorbent material and with one or more tape/strip (13) to secure the drape to the surgical table. The tape/strip (13) is attached to the main sheet with heat seal (9). Patient's tucking area (14) lies between the fasteners. Figure 14 is the back portion of the main sheet without absorbent material and one or more Velcro straps (15) to secure the drape to the surgical table.
It is contemplated that the surgical drape constructed in accordance with the present invention will be tailored and adjusted by those of ordinary skill in the art to accommodate various levels of performance demand imparted during actual use. Accordingly, while this invention has been described by reference to certain specific embodiments and examples, it will be understood that this invention is capable of further modifications. This application is therefore, intended to cover any variations, uses or adaptations of the invention following the general principles thereof, and including such departures from the present disclosure as come within known or customary practice in the art to which this invention pertains and fall within the limits of the appended claims.
