Ambulatory infusion pump

Abstract

A remotely programmable infusion system for administering liquid to a patient includes an infusion pump unit having a pump for infusing liquids operated by means of a control including a programmed processing unit and a memory chip. The processing unit operates in accordance with delivery program data stored in the memory circuit for executing an infusion delivery sequence. An output circuit is operatively disposed between the processing unit and the pump unit to control operation of the pump unit in accordance with the infusion delivery sequence. A wireless data communication circuit is operatively connected to the control for transmitting and receiving data. A programmer remote from the pump unit includes a programmed processing unit, a memory circuit, a user interface operatively associated with the processing unit for entering program commands and configuring delivery program data for storage in the memory circuit and a modem circuit operatively connected to the processing unit for transmitting and receiving data to and from the infusion pump unit. A remote communication interface unit includes a pump interface operatively communicating, in use, with the pump wireless data communication circuit, a programmer interface, including a modem circuit operatively communicating, in use, via a telephone line with the programmer modem circuit and a control circuit operatively connected to the pump interface and the programmer interface for channeling data between the pump interface and the modem circuit.
