SHEET 1 0? 2 PERINEAL PAD The present invention relates to perineal pads for post delivery use in the treatment and prevention of edemas and is a continuation-in-part of Ser. No. 108,464, filed Jan. 21 1971, and now abandoned.
, BACKGROUND OF THE INVENTION A relatively frequent complication following the there is a need for a perineal pad of simple, low cost. construction ensuring sterility, ease of application, and patient comfort when the use of a cold pack is indicated.
THE PRESENT INVENTION A principal objective of the present invention is, accordingly, the provision of perineal pads that meet the requirement of production and use, an objective attained with a pad for use with a separate thermal pack in providing thermal treatment of the urogential region of the perineum, the pad comprising a flexible member with an absorbent member carried thereby, and means for-attaching the pack to the flexible member in a position to underlie that portion of the absorbent member that is to hem engagement with the urogential region of the perineum.
Another objective of the invention is to ensure sterility of the pad while it is being prepared for use, an ob jective attained by providing that the pad comprises an elongated gauze sleeve open at one end and a sterile absorbent member within the central portion of the sleeve, one surface of the central portion to be disposed in engagement with the urogential region of the perineum. The ends of the sleeve are of a length providing forward'andrearward attaching portions by which the a pad may be attached to a patient with said one surface thus positioned. The forward attaching portion is the open end ofthe sleeve. The pad, prior to use, is folded transversely upon itself with respect to said one surface with a fold line between the ends of the, absorbent member but spaced from the'forward end thereof to define, at least when the pad is thus folded, the bottom of a pocket between the sleeve and the other surface of the absorbent member accessible through the open end of the sleeve. The free end of the rearward attaching portion is folded over said one surface and is dimen' sioned so that its free end extends to the forward end of the absorbent member thus enabling the folded pad to be handled without said one surface losing its sterility while a thermal pack is being entered into the pocket through the forward attaching portion.
Another objective of the invention is to provide a pad in which the forward attaching portion is divided along its side to provide separable flaps, one foldable against the free end of the rearward attaching portion and the other foldable against said other pad surface while the thermal pack is being inserted.
A further objective of the invention is to provide a perineal pad which, when the pack is attached thereto for use maintains the absorbent member concave, lengthwise considered, with respect to its surfacethat is to be in engagement with the urogenital region, an objective attained by providing, in the case of a nonfrozen pack, a concave backing therefor and in the case of a frozen pack, providing the frozen pack with a concave surface.
Another objective of the inventionis to provide a perineal pad in which the absorbent member includes a portion extending rearwardly of that part that is to engage the urogenital region and there being of increased thickness.
Yet another objective of the invention is to provide a perineal pad in which the absorbent member includes marginal portions to overlie the sides of the thermal pack.

FIG. 4 is a side view thereof; FIG. 5 is a plan view of the opposite or outer faceof the unfolded pad; I
1 FIG. 6 is a section, on an increase in scale, taken approximately along the indicatedlines 6-6 of FIG. 3;
FIG. 7 is aplan view of an ice bag; FIG. 8 is a side view thereof; FIG. 9 is a longitudinal section through the unfolded pad with the ice pack of FIG. 10 inserted in the pack;
THE PREFERRED EMBODIMENT OF THE INVENTION The perineal pad illustrated by the drawings comprises an elongated flexible member 15, preferably a gauze sheet, with its margins folded to overlap centrally of the outer surface of the pad and secured together in a suitable manner, preferably by an adhesive to provide a sleeve. An absorbent member generally indicated at 16 is encased in the flexible sleeve member 15 between the ends thereof so that said ends provide forward and rearward attaching portions indicated, respectively, at 15A and 158 by which the pad may be detachably secured to a belt. The absorbent member 16 is shown, see FIG. 6 as comprising a bat-like fibre body 17, an outer layer 18 that is preferably moisture resistant and that has its margins overlapping and adhesively secured to the margins of an absorbent layer 19 on the surface of the body 17 that is to engage the urogenital region of the perineum and hereinafter referred to as the inner surface of the pad.
In accordance with the invention, the absorbent.
member 16 includes a posterior portion 16A of increased thickness, conveniently a. doubled-over end.
The forward attaching portion 15A of the flexible sleeve member is divided into inner and outer flaps, see FIGS. 5 and 9, to enable a thermal pack generally indicated at 20, to be inserted between the absorbent member 16 and the outer face of the flexible sleeve member 15. The thermal pack 20 is discussed herein as an ice pack.
The pad is shown in FIGS. 1 and 2 folded transversely at the junction of the absorbent member 16 and its thicker portion 16A enabling theattaching portion 158 to overlie the otherwise exposed inner surface of the absorbent member. The attaching portion A is folded over the attaching portion 158. In practice, the thus folded pad would be within a protective envelope until its use was wanted. The pad, when removed from its envelope may be readied for use without loss of sterility of the inner face thereof by holding it in its unfolded state with the attaching portion 158 overlying said inner face. The outer flap of the attaching portion 15A is then folded downwardly against the other face of the pad facilitating the entry of the pack between the flaps of the forward attaching portion 15A and into the pocket defined by the outer face of the absorbent member 16, the outer face of the sleeve member 15 and the fold line established by the folded over portion 16A of the absorbent member. With the pack 20 in place, the pad is then unfolded and its end portion attached to the belt.
It will be noted that the absorbent member 16 is shown with its margins 16C folded to define pocket sides receiving between them the sides or edges of the pack 20. This construction is preferred when the presence of an ice pack would otherwise be uncomfortably cold to the patient.
The pack isshown as a bag having a neck 20A with lengthwise folds 20B extending lengthwise of its sides enabling the bag to expand as it is filled. After the bag is filled, the neck 20A is then folded over and securely closed by means of a wrap-around 21 of the type including a bendable non-resilient wire 21A secured to one face of the neck 20A near its mouth enabling the folded over portion to be quickly and easily secured. The bag is formed of thin waterproof plastic stock to be so inexpensive that it may be discarded after a single use.
In use, the packs may be filled with crushed ice or they may be water filled and then frozen. It is preferred, however, that the inner surface of the absorbent member 16 be concave. It is preferred that the bags are filled with water and then placed on a convex form 22, see FIG. 10, in a freezer, not shown, thus to provide the frozen bags with the desired concave form. When the contents of the bagsare not frozen as when they are filled with crushed ice, an appropriately shaped backer 23 is inserted between the pack and the outer surface of the flexible sleeve member 15, see FIG. 11.
1. A perineal pad for use with an insert in providing a thermal factor in the treatment of the urogenital region of the perineum, said pad comprising an elongated gauze sleeve open at one end and a sterile absorbent member within the central portion-of the sleeve, one surface of said central portion to be disposed in engagement with said region, the ends of said sleeve being of a length to provide forward and rearward portions by which the pad may be attached to a patient with said one surface thus positioned, the forward attaching portion including the open end of the sleeve, the pad being folded transversely upon itself with respect to said one I surface with the fold line between the ends of the absorbent member but spaced from the forward end thereof to define, at least when the pad is thus folded, the bottom of a pocket between the sleeve and the other surface of the absorbent member accessible through the open end of the sleeve, the free end of the rearward attaching portion being folded over said one surface and dimensioned so that its free end extends to the forward end of the absorbent member thus enabling the folded pad to be handled without said one surface losing its sterility while a thermal pack is being entered into the pocket through the forward attaching portion.
