Device for controlling liquid flow in peristaltic pump as e.g. blood pump, in dialysis apparatus for patient, has sensor device, where signal is emitted for stopping running of pump, when falling below fixed amount of liquid in container

摘要

The device (1) has a wireless capacitive and/or inductive sensor device (4) arranged on a liquid dispensing container (3). A control signal is emitted for stopping running of a peristaltic pump (2), when falling below a fixed amount of liquid in the liquid dispensing container. A liquid inlet of the peristaltic pump is connected with the liquid dispensing container, and pumped liquid is dispensed from a liquid outlet to the in a fluid intake point. The sensor device includes a clamp (5), supporting plate (6), sensor electrode and a control device that evaluates a sensor signal.
