ABSTRACT:
A portable infusion pump for controllably supplying a programmed volume of medicant to a patient. The apparatus generally comprises a small, portable container having a keyboard for programming the mode of operation and operating parameters, whereby a microprocessor controls the pump in the various BASAL, SUPPLEMENTAL OR MANUAL dose delivery modes. The apparatus also contains a photo-coupler controlled driven lead screw assembly for controlling the stroke of the syringe plunger, whereby metered doses of the medicant are injected into the patient; display means for confirming programmed inputs; means for audibly warning of error conditions; and means for recording the total cummulative dosage delivered.
