Abstract

A non-contact wound treatment device having a flexible portion to accommodate patient motion without peeling off. A removable wound heater may be used to treat the wound area.

Claims

1. A wound treatment device, comprising:

an attachment portion in a first plane;

a wound treatment portion including a wound cover in a second plane for defining a wound treatment volume extending between the first plane and the second plane;

a standoff acting between the attachment portion and the wound cover; and

a flexible composite shell attached to the standoff and connecting the attachment portion to the wound treatment portion.

2. The wound treatment device of claim 1, wherein the wound cover is for supporting a heater over the wound treatment volume.

3. The wound treatment device of claim 1, wherein the standoff has a substantially annular configuration.

4. The wound treatment device of claim 1, wherein the standoff comprises a foam ring.

5. The wound treatment device of claim 1, further including a heater disposed on the wound treatment portion over the wound treatment volume.

6. The wound treatment device of claim 5, wherein the wound treatment portion includes a pocket, the heater being disposed in the pocket.

7. The wound treatment device of claim 6, wherein the heater has a substantially planar configuration.

8. The wound treatment device of claim 5, further including a power supply connected to the heater.

9. The wound treatment device of claim 5, wherein the heater is a passive heater including a reflective surface facing the wound treatment volume.

10. A wound treatment device, comprising:

an attachment portion in a first plane;

a wound treatment portion including a wound cover in a second plane for defining a wound treatment volume extending between the first plane and the second plane;

an annular standoff acting between the attachment portion and the wound cover; and

a flexible composite shell attached to the annular standoff and connecting the attachment portion to the wound treatment portion.

11. A wound treatment device, comprising:

an attachment portion in a first plane;

a wound treatment portion including a wound cover in a second plane for defining a wound treatment volume extending between the first plane and the second plane;

a foam ring acting between the attachment portion and the wound cover; and

a flexible composite shell attached to the foam ring and connecting the attachment portion to the wound treatment portion.

12. A wound treatment device, comprising:

an attachment portion in a first plane;

a wound treatment portion including a wound cover in a second plane for defining a wound treatment volume extending between the first plane and the second plane;

a standoff acting between the attachment portion and the wound cover;

a flexible composite shell attached to the standoff and connecting the attachment portion to the wound treatment portion; and

a heater with a reflective surface disposed on the wound treatment portion such that the reflective surface faces the wound treatment volume.
