Surgical drape and method

Abstract

A surgical drape is adapted for use by a woman during childbirth. The surgical drape includes a fecal collection panel having top, bottom, and opposing side edges. An adhesive is applied to a top marginal area of the collection panel directly adjacent its top edge. The adhesive is adapted for temporarily holding the top edge of the collection panel below the vagina and above the anus of the woman when disposed in a lithotomy position, while the bottom edge of the collection panel resides beneath the buttocks. The collection panel defines a protected access aperture designed for enabling ready access by a delivery assistant to the anus of the woman during childbirth. The protected aperture comprises a line of perforations extending perpendicular from the top marginal area of the collection panel towards the bottom edge.

DESCRIPTION OF EXEMPLARY EMBODIMENTS AND BEST MODE

(5) The present invention is described more fully hereinafter with reference to the accompanying drawings, in which one or more exemplary embodiments of the invention are shown. Like numbers used herein refer to like elements throughout. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be operative, enabling, and complete. Accordingly, the particular arrangements disclosed are meant to be illustrative only and not limiting as to the scope of the invention, which is to be given the full breadth of the appended claims and any and all equivalents thereof. Moreover, many embodiments, such as adaptations, variations, modifications, and equivalent arrangements, will be implicitly disclosed by the embodiments described herein and fall within the scope of the present invention.

(6) Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation. Unless otherwise expressly defined herein, such terms are intended to be given their broad ordinary and customary meaning not inconsistent with that applicable in the relevant industry and without restriction to any specific embodiment hereinafter described. As used herein, the article “a” is intended to include one or more items. Where only one item is intended, the term “one”, “single”, or similar language is used. When used herein to join a list of items, the term “or” denotes at least one of the items, but does not exclude a plurality of items of the list.

(7) For exemplary methods or processes of the invention, the sequence and/or arrangement of steps described herein are illustrative and not restrictive. Accordingly, it should be understood that, although steps of various processes or methods may be shown and described as being in a sequence or temporal arrangement, the steps of any such processes or methods are not limited to being carried out in any particular sequence or arrangement, absent an indication otherwise. Indeed, the steps in such processes or methods generally may be carried out in various different sequences and arrangements while still falling within the scope of the present invention.

(8) Additionally, any references to advantages, benefits, unexpected results, or operability of the present invention are not intended as an affirmation that the invention has been previously reduced to practice or that any testing has been performed. Likewise, unless stated otherwise, use of verbs in the past tense (present perfect or preterit) is not intended to indicate or imply that the invention has been previously reduced to practice or that any testing has been performed.

(9) Referring now specifically to the drawings, a disposable surgical drape according to one exemplary embodiment of the present disclosure is illustrated in FIGS. 1 and 2, and shown generally at broad reference numeral 10. The exemplary surgical drape 10 is particularly applicable for use by women during childbirth, and functions to help maintain a clean and sterile delivery area throughout the delivery process. The surgical drape 10 may also alleviate any shame or embarrassment experienced by women after defecating during the pushing phase of labor.

(10) As shown in FIGS. 1 and 2, the exemplary surgical drape 10 comprises a fecal collection panel 11 having top 12, bottom 13, and opposing side edges 14 and 15. The collection panel 11 may be fabricated of any suitable continuous-surface (e.g., fluid impervious) material, such as polyethylene film, polypropylene, SMS fabric or the like. A medical grade contact adhesive 17 is applied to a top marginal area 18 of the collection panel 11 directly adjacent its top edge 12, and extends substantially continuously from one side edge 14 to the other 15. The marginal area 18 of adhesive has an approximate continuous width dimension of 1.0 inches, and functions as described further below to temporarily hold the top edge 12 of the collection panel 11 immediately below the vagina and above the anus of the woman when disposed in a lithotomy position, while the bottom edge 13 of the collection panel 11 resides beneath the buttocks. In one exemplary embodiment, the width of the adhesive marginal area 18 is designed to cover the woman's perineum, while spanning a distance no greater than an anogenital distance between the anus and the vagina. The exemplary adhesive 17 adheres well to the skin, and is latex-free and hypoallergenic to avoid irritation. As shown in FIG. 2, the adhesive 17 is temporarily covered by a peel-away silicone release paper 19 which may be removed by the physician (or other delivery assistant) immediately prior to use.

(11) The exemplary collection panel 11 features a protected aperture 20 designed for enabling ready access by the physician to the anus of the woman during childbirth. The protected aperture 20 comprises a series of perforations 21 formed in a line substantially perpendicular to the top edge 12 of the collection panel 11, and beginning at a point within the marginal area 18 of adhesive and extending towards the bottom edge 13 of the collection panel 11. The length of the protected aperture 20 is between about 1 and 3 inches. To open the aperture 20, the physician simply separates the perforations 21 (e.g., by cutting or tearing) and pulls apart the opposing sides defining the access.

(12) FIGS. 3, 4, and 5 demonstrate one exemplary application of the present surgical drape 10. As shown in FIG. 3, the bottom edge 13 of the fecal collection panel 11 is first positioned beneath the buttocks of the woman in the lithotomy position. As the woman bears down during the pushing phase of delivery, any excreted fecal waste “W” is captured on the collection panel 11. After the woman empties her bowels and prior to delivering the child, the release paper 19 is removed from the marginal area 18 to expose the adhesive 17 and the top edge 12 of the collection panel 11 (with captured fecal waste) is lifted and adhered directly to the legs and buttocks, as shown in FIG. 4. When properly applied, the marginal adhesive area 18 of the collection panel 11 extends between the vagina “V” and anus “A” of the woman. The surgical drape 10 thereby contains and substantially isolates the fecal waste from the vagina “V”, and from the physician and other delivery assistants, during the remainder of the childbirth process. As shown in FIG. 5, if necessary the anus “A” of the woman can be accessed through the protected aperture 20 formed with the fecal collection panel 11 by separating the perforations 21 as described above. After delivering the child, the surgical drape 10 is removed from the woman and discarded. Alternatively, the top marginal area 18 of the collection panel 11 may be lifted and adhered to the woman as shown in FIG. 4 prior to any bowel movement, and may be removed from the woman immediately thereafter and discarded.

(13) In one exemplary embodiment, the surgical drape 10 is substantially square (e.g., 22 inches×22 inches) and the protected access aperture 20 is approximately 2 inches in length. In alternative applications, the surgical drape 10 may be used in other childbirth positions including a side-lying birth position and various upright birth positions, such as squatting, standing, kneeling and all fours. The exemplary surgical drape 10 may offer AAMI Level 3 and AAMI Level 4 protection, and is sufficiently strong and impervious to fluids to effectively control and contain fluid and prevent strike-through.

(14) For the purposes of describing and defining the present invention it is noted that the use of relative terms, such as “substantially”, “generally”, “approximately”, and the like, are utilized herein to represent an inherent degree of uncertainty that may be attributed to any quantitative comparison, value, measurement, or other representation. These terms are also utilized herein to represent the degree by which a quantitative representation may vary from a stated reference without resulting in a change in the basic function of the subject matter at issue.

(15) Exemplary embodiments of the present invention are described above. No element, act, or instruction used in this description should be construed as important, necessary, critical, or essential to the invention unless explicitly described as such. Although only a few of the exemplary embodiments have been described in detail herein, those skilled in the art will readily appreciate that many modifications are possible in these exemplary embodiments without materially departing from the novel teachings and advantages of this invention. Accordingly, all such modifications are intended to be included within the scope of this invention as defined in the appended claims.

(16) In the claims, any means-plus-function clauses are intended to cover the structures described herein as performing the recited function and not only structural equivalents, but also equivalent structures. Thus, although a nail and a screw may not be structural equivalents in that a nail employs a cylindrical surface to secure wooden parts together, whereas a screw employs a helical surface, in the environment of fastening wooden parts, a nail and a screw may be equivalent structures. Unless the exact language “means for” (performing a particular function or step) is recited in the claims, a construction under 35 U.S.C. § 112(f) [or 6th paragraph/pre-AIA] is not intended. Additionally, it is not intended that the scope of patent protection afforded the present invention be defined by reading into any claim a limitation found herein that does not explicitly appear in the claim itself.
