  • Patent number: 5658133
    Abstract: A medical infusion pump (10) for delivering liquids to a patient includes an elastomeric pump chamber (140) contractable between a refill position and a discharge position. An inlet valve (122) is operatively associated with an elastomeric inlet (142) supplying liquid to the pump chamber (140). The inlet valve (122) is selectively positionable in an open position permitting and a closed position preventing flow of liquid between the inlet (142) and the pump chamber (142). An outlet valve (124) is operatively associated with an elastomeric outlet (144) which conveys liquid from the pump chamber (140). The outlet valve (124) is selectively positionable in an open position permitting and a closed position preventing flow of liquid between the outlet (144) and pump chamber (140). A pump motor (256) and associated plunger (120) contracts and expands the pump chamber (140) between the refill position and the discharge position.

  • Patent number: 5630710
    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.
