Abstract
The invention concerns a pumping device that includes a pump having a pumping chamber with a variable volume, an inlet that communicates with the pumping chamber and a valve, an outlet that communicates with the pumping chamber and a valve, and an actuator adapted to change the volume of the pumping chamber. A fluidic pathway in the pumping device includes the inlet, the pumping chamber, the outlet, and a downstream line situated downstream of the outlet valve. The pumping device also includes a pressure sensor for measuring the pressure between the valves of the pathway, and a processing means for processing the received pressure data from the pressure sensor. The invention also concerns a method for detecting a dysfunction in the pumping device.
