AN INFUSION DEVICE FOR MEDICAL FLUIDS.

摘要

The infusion device comprises a pusher for a plunger (10) of a syringe (6) containing a liquid to be infused. A load cell (14) measures the push force. An encoder associated to a motor (13) commanding the pusher measures the displacement of the pusher. A controller (15) signals an alarm when the ratio between the variation of the push force and the displacement exceeds a predetermined threshold. The device, which serves for infusing an anticoagulant into an extracorporeal blood circuit in a dialysis apparatus, is able to signal an onset of an anomalous situation of lack of infusion in good time.
