摘要：
A fluid infusion device includes a pump having a rotor and a stator. A rotor cam element rises from a reference surface of the rotor. The stator includes a cam element having a stator cam surface. The cam elements axially displace the rotor as the rotor revolves. Inlet and outlet valves open and close as a function of angular and axial position of the rotor. A motor actuates the rotor to pump fluid to a body, via a subcutaneous conduit. First and second contact elements are located on the rotor. A sensing element on the stator cooperates with a detection circuit to detect when the sensing element makes contact with the first sensor contact element and the second sensor contact element. The detection circuit monitors a detection signal obtained from the sensing element to determine an operating condition of the fluid pump mechanism.
