Negative Pressure Wound Therapy Systems Capable of Vacuum Measurement Independent of Orientation
First Claim
1. A portable negative pressure wound therapy system, comprising:
- a dressing assembly for positioning over a wound to apply a negative pressure to the wound; and
a canister assembly including;
a control unit;
a vacuum source disposed in the control unit;
a pressure sensor in communication with a processor unit of the control unit;
a collection canister having an inlet conduit in fluid communication with the dressing assembly, a first chamber to collect wound fluids from the dressing assembly, an inlet port coupled to the inlet conduit to introduce the wound fluids from the dressing assembly into the first chamber, a suction port to communicate with the first chamber and the vacuum source; and
a pressure sensor port to communicate with the first chamber and the pressure sensor, the pressure sensor port in fluid communication with a “
T”
-off point between the inlet conduit and the inlet port.

Abstract
A portable negative pressure wound therapy system includes a dressing assembly for positioning over a wound to apply negative pressure to the wound and a canister assembly. The canister assembly includes a control unit, a vacuum source disposed in the control unit, a pressure sensor in communication with a processor unit of the control unit, and a collection canister. The collection canister includes an inlet conduit in fluid communication with the dressing assembly, a first chamber to collect wound fluids, an inlet port coupled to the inlet conduit to introduce the wound fluids from the dressing assembly into the first chamber, a suction port to communicate with the first chamber and the vacuum source, a pressure sensor port to communicate with the first chamber and the pressure sensor. The pressure sensor port is in fluid communication with a “T”-off point between the inlet conduit and the inlet port.
