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.
Claims30
A wound treatment device for attachment to a patient's skin surface and for accommodating stretching motion of said patient's skin surface from a first nominally relaxed state to a second stretched state, said wound treatment device comprising:
- a wound attachment portion lying in contact with said patients's skin surface, said patient's skin surface defining a first plane;
- a wound treatment portion defining a wound treatment area on said patient's skin surface, and defining a non-contact wound treatment volume over said wound treatment area;
- said wound treatment portion including a standoff extending from said first plane to a second plane, said second plane being parallel to said first plane;
- a transition portion for coupling said attachment portion to said wound treatment portion, said transition portion including a membrane connected to said attachment portion proximate said first plane and connected to said standoff;
- whereby, said attachment portion projected onto said patient's skin surface defines a projected attachment area;
- said wound treatment portion projected onto said patient's skin surface defines a projected wound treatment area;
- said transition portion projected onto said patient's skin surface defines a projected transition portion area;
- said wound covering having a nominal total projected area corresponding to said first relaxed state and having an increased total projected area corresponding to said second stressed state wherein said total projected area is increased over said nominal total projected area;
- and said increased total projected area results primarily from compliance of said transition portion.
A wound treatment device for attachment to a patient's skin surface said wound treatment device comprising:
- a wound attachment portion lying in contact with said patients's skin surface, said patient's skin surface defining a first plane;
- a standoff portion extending from said first plane to a second plane substantially parallel to said first plane said standoff portion defining a wound treatment volume over a wound treatment area;
- a transition portion connected to said standoff portion and connected to said attachment portion;
- a planar heater located in said second plane supported by said standoff for radiating heat onto said wound treatment area.
A wound treatment device for attachment to a patient's skin surface said wound treatment device comprising:
- a wound attachment portion lying in contact with said patients's skin surface, said patient's skin surface defining a first plane;
- a standoff portion extending from said first plane to a second plane substantially parallel to said first plane said standoff portion defining a wound treatment volume over a wound treatment area;
- a transition portion connected to said standoff portion and connected to said attachment portion;
- a heat reflector located in said second plane supported by said standoff for reflecting heat onto said wound treatment area.
A method of making a wound treatment device comprising the steps of:
- forming a unitary cup shaped member having an attachment portion and having a transition portion and having a wound treatment portion;
- removing an area of said cup member forming a window zone;
- attaching a wound cover to said window zone;
- positioning and attaching a wound enclosure ring proximate said wound cover;
- adhesively applying a release liner to said attachment portion.
A method of treating a wound comprising the steps of:
- positioning a planar radiant heat source above said wound;
- enclosing the wound with a non-contact wound treatment device.
