Abstract
A micropump and a disposable pump body thereof are disclosed. The micropump includes the pump body and an actuator device. The pump body includes a chamber, an inlet communicating with the chamber, an outlet communicating with the chamber and a covering membrane on top of the chamber. The actuator device includes an actuator and a transmitting post. One of the two ends of the transmitting post connects to the actuator. The other end of the transmitting post abuts against the membrane. Since the pump body is separated from the actuator device, the pump body is disposable and can be replaced after use to avoid cross-infection of disease, particularly useful for medical liquid delivery.
