Infusion apparatus










Image Number 7 for United States Patent #4752289.

An infusion pump pressure monitor comprises a drive (26, 27, 30, 31) for an infusion pump, a pressure sensor (38) to monitor the delivery pressure downstream of the pump, and a programmed computer (34, 35). The computer (34, 35) is programmed to monitor the maximum delivery pressure that occurs during an initial operating period, and then, subsequently to monitor the delivery pressure downstream of the pump for the remainder of the delivery period of the infusion pump. The programmed computer (34, 35) is programmed to disable the drive (26, 27, 30, 31) for the infusion pump if the monitored delivery pressure differs by more than a predetermined amount from the maximum pressure monitored during the initial operating period. The infusion liquid is carried by a disposable infusion set having a pressure responsive chamber (1) located in a key-hole shaped slot (44) in the pressure monitor.
