Abstract: Low power peristaltic medicine pump and filter for infusion of medicinal solutions. The pump includes a pump housing, a low durometer PVC pump tube; fit within an interior circular groove of the pump housing, tube slots, a rotor cavity within the walls of the pump housing bearing hole and recessed motor mounting body holes. A sealed geared motor in a motor recess in the bottom of the pump housing and a shaft and drive pin extend from the motor through a bearing hole in the pump housing to drive a pump rotor. Rotor mounted plungers offset at an angle to the radii of the pump rotor body to minimize internal friction for low power consumption and are spring loaded outwardly to depress plunger mounted rollers against the PVC pump tubing for subsequent peristalic pumping action through an inset PVC pump tube. A knurled knob loading tool positions on the pump rotor. Feed fingers attached to a circular plate on the loading tool facilitate loading of the PVC pump tube into the inner groove of the pump housing.

Abstract: Drug dispensing system for dispensing of drugs from a reservoir or external reservoir such as a standard I.V. bag through a drug dispenser according to a preselected algorithm controlling a motor where a CPU pumps the drug. An external controller for the drug dispenser stores a plurality of parameters including a patient number, name, drug dispenser number, date, time, drug, an algorithms for dispensing the drug including dosage levels and frequency of dosage where the algorithm is stored in the external controller and the program is subsequently stored in the CPU of the drug dispenser for subsequent controlling of the motor driving the pump for dispensing of the drug. The external controller also includes an LCD display for medical personnel interaction and a printer for hard copy storage of the selected algorithm and other information as programmed into the external controller by a keyboard.
