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.

摘要： A negative pressure wound therapy system creates a negative pressure environment in the opening of a wound-dressing unit and a positive pressure environment in the collecting bag. Then a positive pressure detecting procedure is proceeded in the positive pressure environment and a negative pressure detecting procedure is proceeded in the negative pressure environment. The detecting results are sent to determine whether a micro pump is stopped.

摘要： An actuator has a pump head detachably connecting to an external motor. When the actuator extracts the pus and the infection subjects, the fluid only flows through the pump head so that only the pump head needs to be made of biocompatibility materials. Therefore, the manufacturing cost is reduced. Moreover, because the motor is not made of biocompatibility materials, only the pump head needs to be treated as medical wastes so that the disposal cost is reduced. Furthermore, since the pump head is detachable from the motor, the infected pump head is replaced independently to lower the replacement cost.
