Abstract

A pressure dressing provided with a cushion for tightly holding an element of grafted skin, wherein the portion opposite the portion in contact with the body (5) has a rigid plate (4).

Claims

1. A skin graft pressure dressing for pressing a skin graft against a body member,

said pressure dressing comprising in combination:

a fluid-containing cushion for engaging and exerting pressure against the entire skin graft and the surrounding normal skin on the body member,

said cushion having thin flexible walls enclosing a space for receiving a fluid material,

said walls being made of a thin flexible resilient foil material,

a rigid pressure plate engaging said cushion on the side thereof opposite from the skin graft for pressing said cushion against the skin graft and the surrounding normal skin,

said plate being made of a transparent material,

the foil material between said plate and the skin graft also being transparent to render the skin graft clearly visible for inspection through said plate and said cushion,

means for securing said plate to the body member while exerting pressure upon said plate to press said plate against said cushion so that said cushion will exert pressure against the skin graft,

and means for producing, maintaining and controlling the pressure of the fluid material within said cushion.

2. A skin graft pressure dressing according to claim 1, in which said plate is made of transparent thermoplastic material which is moldable in shape with the aid of heat.

3. A skin graft pressure dressing according to either claim 1 or 2, in which said plate has a shape conforming generally to the shape of the body member on which the skin graft is to be mounted.

4. A skin graft pressure dressing according to claim 1, 2 or 3, in which said plate is fixedly secured to said cushion.

5. A skin graft pressure dressing according to claim 1, 2 or 3, in which said plate is one of a plurality of plates secured to said cushion.

6. A skin graft pressure dressing according to claim 1, 2, 3, 4 or 5, in which said fluid material in said cushion is compressed air, the pressure of which is produced, maintained and controlled by said last mentioned means.
