ABSTRACT:
A peristaltic pump is provided with a housing, a pump head in the housing, and a receiving path defined along a housing and pump head for receiving tubing. An air sensor assembly in the pump has a slot for receiving a section of the tubing in the receiving path. A position covering the receiving path and an open position exposing the receiving path. An engaging member is provided for pushing the tubing in the slot. The engaging member is pivotally mounted to the door for rotation about an axis parallel to the door pivot axis. The engaging member has a ram for contacting the tubing. The orientation of the ram relative to the door can change as the ram enters the slot when the door closes so that the tubing is pushed relatively evenly and along a substantially straight line into the slot.
