Abstract

Metering apparatus for use with a parenteral fluid infusion set and having a rotor provided with pressure rollers for pumping the fluid by peristaltics, the rotor being driven by a stepper motor and being controlled by pulses generated at a user-adjustable rate, second generating means being provided to generate pulses at a fixed minimum rate, the second generating means coming into operation when a predetermined volume of fluid has been infused unless the user adjustable rate was set below a predetermined level when operation of the second generating means is inhibited. The apparatus may include a flow restrictor to provide back pressure for the pump to work against and may include means to detect an occlusion in the tubing whereupon the rotor is stopped, and to detect an air bubble or power supply failure resulting in an alarm. The stepping motor may be supplied with pulses via optical isolation units to prevent interference.
