摘要:
A pump for pumping fluid includes a tube platen, a plunging mechanism, a bias member, inlet and outlet valves, an actuator mechanism, a position sensor, and a processor. The plunger is configured for actuation toward and away from the infusion-tube when the tube platen is disposed opposite to the plunger. The bias member is configured to urge the plunger toward the tube platen. The bias member can be the sole source of force of the plunger against a tube which allows the use of the plunger’s position to estimate volume of fluid within the tube, check for the integrity of the tube, check for leaks of the inlet and outlet valves, and/or check for occlusions upstream or downstream of the pump.
