Abstract: A lever including a far end to engage an infusion tubing is provided. The lever includes a pivot end configured to fit into a shaft and to allow the lever to rotate about a shaft axis, the pivot end including a pocket to capture a spring having a leg protruding outside. The spring is configured to apply a bias from the lever against a door assembly. The lever includes a tab disposed on an outer side of the far end and configured to interface with the door assembly, and a pusher protruding into an inner side of the far end and configured to contact the infusion tubing when the far end engages the infusion tubing. The pusher applies a downward pressure to the infusion tubing when the door assembly is closed until the infusion tubing is properly aligned with an air-in-line sensor disposed on both sides of the tubing.
