ABSTRACT:
An infusion pump for use with standard pre-filled single dose IV bags. The pump includes a housing having a lid which opens and closes so that the IV bag can be inserted and supported in a delivery mode position. A platen surface is positioned along one side of the bag while a compression roller is mounted for movement along the other side of the bag. A control circuit actuates drive means which moves the compression roller in a direction towards a dispensing port of the bag while the roller applies force for expelling solution from the bag. Forward movement of the pressure roller is controlled to maintain solution pressure within the bag at a predetermined level. Electromechanical indicators, alarms and interlock features are provided for purposes of safety and for monitoring the infusion process.
