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 wound closure strip comprising:

an elongate imperforated pad member formed from a polymeric material of a density to permit the pad member to breathe and expose the wound to ambient air, said pad member being constructed of a material having an easy stretch axis and a hard stretch axis orthogonal to the easy stretch axis, thus exhibiting uni-directional stretch properties said pad member being cut from said material such that its longitudinal axis is oriented at a predetermined oblique angle relative to both said axis of said material such that the pad member has modulus of elasticity (E_t) irrespective of thickness, in the range of 0.5 to 110 pounds per inch, said material having a low elastic recovery characteristic; and

adhesive means bonded to at least one surface of said pad member for adhering said pad member to human skin.

2. A wound closure strip as in claim 1 and further including a backing member upon which said adhesively coated pad member is detachably mounted.

3. A wound closure strip as set forth in claim 1 wherein said adhesive is a low allergenic material.

4. A wound closure strip as set forth in claim 3 wherein said low allergenic material is an acrylic-based adhesive.

5. A wound closure strip as set forth in claim 1 wherein said pad member is configured on said backing member as a plurality axially spaced apart parallel lengthwise strips.

6. A wound closure strip as set forth in claim 1 wherein said pad member comprises a lengthwise portion from which a plurality of strip portions extend in a parallel axially spaced apart relation, each of said strip portions being orthogonal to said lengthwise portion.
