Patent ID: 8579872

Claim:
A system for treating a tissue site with reduced pressure, the system comprising: a reduced-pressure dressing for disposing proximate to the tissue site, the reduced-pressure dressing comprising an interface distribution manifold for placing proximate to the tissue site, a dressing sealing member, and a reduced-pressure interface; a wireless, reduced-pressure pump fluidly coupled to the reduced-pressure dressing, the wireless, reduced-pressure pump comprising: a RFID antenna, a first processor coupled to the RFID antenna, a micro-pump device coupled to the first processor for receiving power therefrom and developing reduced pressure, the micro-pump device comprising a piezoelectric pump, a first pump-sealing member and a second pump-sealing member, wherein the first pump-sealing member and the second pump-sealing member are at least partially coupled to form a pump pouch in which the micro-pump device is disposed, a fluid reservoir fluidly coupled to the micro-pump device, a first distribution manifold, an absorbent layer, and a diverter layer, wherein the first distribution manifold, the absorbent layer, and the diverter layer are disposed within the pump pouch formed by the first pump-sealing member and the second pump-sealing member; a base unit having a RFID reader; and wherein the RFID reader is configured to provide power to the RFID antenna such that the micro-pump device is powered.
