Patent ID: 8409160

Claim:
A reduced-pressure treatment device for use with a system for treating a tissue site on a patient with reduced pressure, the reduced-pressure treatment device comprising: a canister unit comprising: a pump head including at least two diaphragms, the pump head for fluidly coupling to the tissue site to provide reduced pressure to the tissue site, and a fluid reservoir fluidly coupled to the pump head for collecting fluid from the tissue site; a pump control unit fluidly separate from the canister unit and configured to provide pump energy to the pump head to cause the pump head to generate reduced pressure and operatively coupled to at least one of the at least two diaphragms to measure the displacement of the respective diaphragm, the pump control unit comprising: a control device, and a power subsystem for providing power to the control device; at least one linking interface associated with the canister unit and the pump control unit, the at least one linking interface for providing the pump energy to the pump head; and wherein the control device and the power subsystem provide the pump energy to the at least one linking interface to generate reduced pressure.
