  • Patent number: 7059840
    Abstract: An apparatus for pumping fluid through tubing comprising a stop platen is disclosed. The stop platen is operatively arranged to depress a wall of the tubing along a section of a longitudinal axis of the tubing. The stop platen is narrower than the tubing along a transverse axis of the tubing. The invention further comprises a cabinet containing the stop platen, a door rotatably fixed to the cabinet, and locking means for preventing rotation of the door. The locking means are operatively arranged to be unlocked by a tubing occluder.

  • Patent number: 5567120
    Abstract: A holder for an IV tube roller clamp is removably secured in the housing of an electronic infusion device, and has in opposite ends thereof a pair of photo-electric devices, one of which detects when the roller of the clamp is in its tube opening position, and the other detects when the roller is in tube closing position. A lever is pivotal on the housing between a closed position in which it operatively connects the IV tube to a pump unit in the housing, and an open position in which it permits removal of the IV tube from the unit. The spring-loaded armature of a solenoid prevents the lever from being opened until the solenoid coil is energized, and the photo-electric devices prevent the solenoid coil from being energized until the roller is in its tube closing position. When closed, the lever overlies part of the tube channel in which the IV tube is seated and also shifts a pressure plate in the pump unit to a position in which a lip thereon overlies another portion of said channel.
