Abstract
A portable and programmable infusion pump system is disclosed for injecting one or more medicinal substances into an individual under the control of the individual. A common controller unit and microprocessor is provided for one or more pump units. Each pump unit includes a chamber for holding a medicinal substance, an infusion tube that is connected to the chamber and is adapted to be connected to the individual, and a motor driven pump for pumping the medicinal substance through the infusion tube. The individual programs the microprocessor to perform one or more infusion processes by use of a keyboard, a card reader, a bar code reader, or a modem. Each motor and pump are controlled in accordance with its program parameters as contained in the programmed microprocessor. A pressure sensor and an air bubble detector is associated with each infusion tube, and these sensors and detectors are connected to the microprocessor.
