Abstract
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.
