Abstract

A postoperative garment for protection and improved healing of a wound, injury or disease site comprising a first panel and a second panel, the panels being constructed of a fabric structure comprising a blend of at least one polyester fiber and at least one elastic fiber. The fabric has an elasticity of about 200-220+/-10% in both the warp direction and in the fill direction, the difference between the warp and fill direction elasticity preferably being no more than about 3% to about 5%, a compression modulus of about 1 to about 4, and a breathability measurement of 70-100% moisture loss within 30 minutes and an approximate skin surface temperature reduction of about 4-6° F. within about 3-7 minutes as measured by evaporative cooling, and the panels being attachable to each other along one edge by a closure means, such as mated hook and loop fasteners. The improved universal compression characteristics, breathability and thermoregulation provide enhanced ability to promote healing and protect the wound site.

Claims

1. A postoperative garment for protection and improved healing of a wound, injury or disease site, comprising:

a first panel and a second panel, said panels being constructed of a fabric structure having warp and fill directions with at least one elastic fiber and a blend of at least one selected from a group consisting of polyester and nylon fiber such that said fabric has an elasticity of about 200-220+/-10% in both the warp direction and in the fill direction, the difference between the warp and fill direction elasticity being no more than about 3% to about 5%, a compression modulus of about 1 to about 4, and a breathability measurement of 70-100% moisture loss within 30 minutes and an approximate skin surface temperature reduction of about 4-6°

F. within about 3-7 minutes as measured by evaporative cooling, said panels being attachable to each other along one edge by a closure means.

2. The garment of claim 1, wherein said polyester is selected from a group consisting of cationic dyeable polyester, and a continuous filament yarn.

3. The garment of claim 1, wherein said polyester comprises a cationic dyeable, hollow core, continuous filament yarn with an approximate 20% void in fiber interior.

4. The garment of claim 3, wherein said continuous filament yarn has a tetrachannel cross section.

5. The garment of claim 1, wherein said elastic fiber is composed of a synthetic elastomeric material.

6. The garment of claim 1, wherein said garment has substantially equal compressive force in the warp and fill directions.

7. The garment of claim 6, wherein said compressive force is from about 7 to about 25 mmHg.

8. The garment of claim 1, wherein said closure means is selected from a group consisting of mated hook and loop fasteners, zippers, hook and eye closures, snaps, and buttons.

9. The garment of claim 1, further comprising a surgical drain attached to said garment for permitting passage of fluids there through.
