## Abstract

A pre-stressed pressure device for treating a wound or reduce scarring of a skin of a patient includes a substrate assembly having a first surface, a pressure member having a curve in a central portion, the pressure member being secured to the substrate assembly; a treatment device for exerting a pressure on the wound or the scarring, the treatment device being connected to a first area of the first surface; and an adhesive for applying the pressure bandage to the skin, the adhesive being disposed on a second area of the first surface, the first and second areas being non-overlapping.

## Claims

### Claim 1

A pressure device for treating a wound or reducing scarring of a skin of a patient, the pressure device comprising:
a substrate assembly having a first surface side and a second surface side, as well as first and second end portions;
a pressure member having a curved state and a non-curved state, the pressure member having an inner surface and an outer surface, the pressure member also comprising a central portion and first and second end portions,
the central portion having a convex curved shape along the outer surface of the pressure member when the pressure device is not adhered to the skin of the patient, and the pressure member being connected to the second surface side of the substrate assembly;
a treatment device connected to the outer surface of the pressure member, wherein the first and second end portions of the pressure member extend beyond ends of the treatment device; and
an adhesive located on the first and second end portions of the substrate assembly and the first and second end portions of the pressure member for applying the pressure member to the skin of the patient;
wherein when the adhesive secures the skin of the patient to the first and second end portions of the substrate assembly and the first and second end portions of the pressure member, and the pressure member is in the non-curved state, the pressure member exerts end forces directing the first and second end portions of the pressure member away from the skin of the patient and a central force directing the central portion of the pressure member towards the skin of the patient.

### Claim 2 (depends on 1)

The pressure device of claim 1, wherein the pressure member exerts a pressure ranging from 10-25 mm Hg to the wound when secured to the wound in the non-curved state.

### Claim 3 (depends on 1)

The pressure device of claim 1, wherein the substrate assembly comprises a woven cloth, cotton, artificial and/or natural fibers, artificial and/or natural gel materials, natural or artificial foamed rubber, or a combination thereof.

### Claim 4 (depends on 1)

The pressure device of claim 1, wherein the treatment device comprises a silicone pad, a gauze, an anti-bacterial agent treated pad, a coagulant agent treated pad, a hemostatic agent treated pad, a vitamin E treated pad, an antibiotic treated pad, an antiseptic treated pad, a botulism toxin treated pad, or a growth factors treated pad.
