The required pressure for administering the drug comes from the elastomeric layer that is molded inside the pump. When the pump is filled, the layer is stretched. The elastic constriction drives the liquid through the tubing and eventually through a flow restrictor out into the patient connection. The pressure is consistent until near the end of the infusion, when there will usually be a pressure spike resulting in a higher flow rate. The accuracy of the flow rate is controlled by a flow restrictor (glass capillary or steel ...
