Abstract

A closure band of water-vapor permeable, flexible, elastic plastic spans a cut in the flesh and holds the cut closed. Flesh-engaging penetrants such as hooks are partly embedded in or are part of the band and engage the flesh either side of the cut. Adhesive on the band also contacts the flesh and helps hold the penetrants embedded. A tear strip overlying openings through the band, when removed, allows inspection of the cut.

Claims

1. A wound closing device for engaging the flesh adjacent an elongated cut comprising a band of flexible material of predetermined thickness having an inside face and an outside face, a pair of integral rib portions each upstanding from said outside face and spaced from each other to leave a central portion of said band of said predetermined thickness adapted to overlie said cut and spaced from the ends of said band to leave side portions of said band of said predetermined thickness, means defining areas of adhesion on said inside face at said side portions thereof, and a pair of individual hooks, each hook having a base embedded in a respective one of said rib portions and having a needle connected to said base and extending therefrom and projecting through said inside face adjacent an area of adhesion, said needles being in positions converging toward each other.

2. A device as in claim 1 in which each of said rib portions includes a plurality of said hooks, all of said hooks in one of said rib portions having said needles thereof substantially parallel to each other.

3. A device as in claim 1 in which said needle is curved.

4. A device as in claim 1 in which said band is elastic.
