摘要：
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.
