NEGATIVE PRESSURE WOUND THERAPY SYSTEM WITH A BUFFERING UNIT
First Claim
1. A negative pressure wound therapy system comprising a controller, a sensor, an actuator, a collector, a wound dressing, and a buffering unit that responds to the negative pressure variation and compensates for the negative pressure loss in the wound, whereinthe controller is electrically connected to the sensor and the actuator;
- the actuator is connected to the buffering unit and the collector;
the sensor is connected to the buffering unit; and
the buffering unit is connected between the wound dressing and the actuator.

Abstract
A negative pressure wound therapy system has a buffering unit connected between an actuator and a wound dressing. The buffering unit has similar physical condition with the wound, and consumes its negative pressure to compensate for the negative pressure loss in the wound to resist the pressure rise in the wound during slight leakage. The buffering unit also keeps the actuator from directly operating on the wound to reduce the pain of the patient while lowering the pressure in the wound.
