Abstract

An adhesive strip-like bandage for application to skin wounds for sealing the wound without surface stitches or staples. The wound closure strips may be fabricated from a bias cut, woven, or non-woven, polymer-based material or other film, exhibiting uni-directional stretch properties which permits the strips to stretch in a controlled manner during wound healing. The strip bandages are detachably mounted to a backing member and in one configuration comprise a comb-like structure.

Claims

1. A process for fabricating wound closure strips comprising:

(a) feeding a continuous web of woven or non-woven polymer material of a type exhibiting an easy stretch axis and a hard stretch axis orthogonal to said easy stretch axis and having an adhesive backing on one surface of said web past a first die cutting station;

(b) feeding a backing material in juxtaposed relation to said web of material past a second die cutting station;

(c) aligning said first die cutting station at a bias angle relative to said easy stretch axis of said polymer material, said bias angle being selected to obtain a predetermined modulus, E_t, in a selected stretch direction in the range of from 0.5 pounds per inch to 110 pounds per inch;

(d) die cutting individual pad members from said web of material at said first die cutting station and depositing said die cut pad members on said backing material; and

(e) die cutting said backing material at said second die cutting station so as to produce individual detachably mounted wound closure bandages on the cut backing material having said predetermined modulus.
