Abstract

The infusion pump is for transfusion and perfusion, allowing chronological control by variation of the motor angular displacement, and monitoring by electrical capacity. It has a very small housing with a peristaltic pump having three rollers, whose flow time is regulated by a graduated control multiplying by ten the time of perfusion. The control adjusts motor angular velocity to suit the viscosity of the product. There can be an electronic circuit with an oscillator, a frequency divider, a divider by ten of the frequency, an inverter allowing frequency selection, a frequency divider programmable from 1 to 9, an 11-position switch, a power amplifier, a pump driving motor and an indicator light.
