Wound protector with transparent cover
First Claim
1. A wound protector comprising:
- a planar base pad having a central opening therethrough of an area larger than the wound area to be protected, a recess in the top surface of said base pad forming a ledge around said central opening, said ledge to receive a surgical sponge, said pad being of a non-allergenic material selected from the group consisting of felt-like, nonwoven and closed-cell foamed substances, said pad having a thickness such that a surgical sponge placed in said recess will not contact said wound area, said pad further having a non-allergenic adhesive on its undersurface for adhering said protector to the skin, and a pre-use, releasable foil covering the entire undersurface of said base pad including said central opening to protect said adhesive prior to use of the device; and
a flat, transparent cover of the same configuration as said base pad, one side of said cover being secured to the upper surface of said base pad over the length of that side of the base pad and out to the edge of said recess, the opposite side of said cover having an outwardly projecting lip, said cover being semi-rigid and having sufficient flexibility so that when the lip is raised from the base pad, the cover will have a hinge-like action at the area of adhesive securement to the base pad, the undersurface of said cover in said lip area being coated with a second adhesive of a tacky type which will hold the other end of said cover on said base pad and will permit the said other end of said cover to be released from said base portion, said cover further having at least two ventilating openings through said cover, said openings being so positioned on said cover over said ledge.

Abstract
The wound protector comprises a base pad of a pliable fibrous or foamed non-allergenic material in an angular form which may be circular, rectangular, square, oval or triangular. Since the purpose of the wound protector is to prevent the wounded portion of the body from being contacted by anything other than medicants, the central opening of the base pad must be larger than the wounded area about which it is to be placed. A marginal ledge is formed in the top surface of the base pad around the inner opening for the purpose of receiving surgical gauze or sponge containing a medicant, should such be required, for treatment of the wounded area. As the wound protector is to be provided with a transparent cover, the top surface of the base pad between the marginal ledge and the outer vertical surfaces of the pad must be of sufficient width to support the transparent cover as well as provide adequate area for securing at least a part of the cover to the pad. The transparent cover is of a transparent plastic material having some flexibility but lying flat on the upper surface of the base pad when in the normal position. The transparent cover is of the same shape as the base pad and is secured at one side by a permanent adhesive material. While the transparent cover will normally lie flush with the upper surface of the base pad after it is adhered to the pad, a tacky adhesive may be employed on the side of the top surface of the pad opposite the side securing the cover thereto to permit the cover to be lifted up for treatment purposes and then held firmly but releasably to the pad after the treatment. The wound protector is applied to the body area by a non-allergenic adhesive material.
