Device for infiltration of anaesthetizing fluids has motor operated occlusion roller pump, with pump output and flow rate adjustable by hand potentiometer, pneumatic capsule, or sensitive foot switch with integrated potentiometer

摘要

The device for the infiltration of fluids consists of an occlusion roller pump operated by a motor. The starting, interrupting, ending and control of the motor power, and therefore the pump output and flow rate, are effected by a hand potentiometer in the appliance and in the handle, a pneumatic capsule in the handle with a pressure converter, or a sensitive foot switch with an integrated potentiometer, all of which enable a variable flow. A sterile packed disposable PVC-plastic tube system is for the transporting of the fluid.
