Abstract
A peristaltic pump disclosed herein includes a raceway, a plunger, a motor, and a heater. The raceway is configured to retain a tube (e.g., an IV tube). The plunger acts on the tube disposed within the raceway. The motor engages the plunger to actuate the plunger. The heater is disposed in thermal-conductive contact with the tube. That is, the heater, either through direct or indirect application, heats the tube.
