METHOD AND DEVICE FOR PROVIDING INTERMITTENT NEGATIVE PRESSURE WOUND HEALING
First Claim
1. A method for providing intermittent negative pressure wound healing which includes the steps of:
- (a) applying a negative pressure compressible therapeutic dressing about a wound;
(b) compressing the therapeutic dressing using negative pressure to subject the wound and the therapeutic dressing to a first predetermined pressure which is low enough to provide therapy to the wound and high enough to maintain a seal between the dressing and the wound; and
(c) decompressing the therapeutic dressing to a second sub-atmospheric pressure above the first predetermined pressure sufficient to maintain the dressing in a generally sealed contact with the wound while relaxing compression about the wound.

15. A therapeutic device for providing intermittent negative pressure wound healing includes fluid moving means for one of raising, compressing, or transferring fluid, a compressible therapeutic member operably connected to the fluid moving means and actuated thereby, the compressible therapeutic member operably disposably used on a patient in a manner to deliver therapy to the patient as function of actuation of the fluid moving means;
- and control means operably associated with the fluid moving means for controlling application of a negative pressure to the compressible therapeutic member about a wound in a manner to compress the compressible therapeutic member using negative pressure to subject the wound and the compressible therapeutic member to a first predetermined pressure which is low enough to provide therapy to the wound and high enough to maintain a seal between the compressible therapeutic member and the wound and decompressing the compressible therapeutic member to a second sub-atmospheric pressure above the first predetermined pressure sufficient to maintain the compressible therapeutic member in generally sealed contact with the wound while relaxing compression about the wound, and a power source to supply power to the fluid moving means and said control means.
