  • Patent number: 4399816
    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.
