  • Patent number: 5437635
    Abstract: A flow limiter mechanism for use with an infusion pump of the type operating upon a disposable cassette held by the infusion pump and having a flow tube connected to the cassette. The flow limiter includes a receiving channel located on the infusion pump adjacent to the disposable cassette held by the infusion pump. A tube pincher is operatively associated with the receiving channel to pinch the flow tube in a clamped position and mechanically retractable to an unclamped position to allow the flow tube to open. Electrical controls are connected for selectably operating the tube pincher from the clamped closed position to the unclamped opened position while the disposable cassette is held by the infusion pump. A flow clip is attached to the flow tube and is manually operable between opened and closed clipping positions prior to inserting the disposable cassette into the infusion pump.

  • Patent number: 5169106
    Abstract: A quick attach/release pole clamp is mounted on the side of a medical instrument case. A stationary clamp member is secured to the case and a movable clamp member slides in a slot oriented at a slight acute angle to the vertical, so that it moves toward and away from the stationary clamp member as it moves up and down the slot. A spring biases the movable clamp member toward the top of the slot so that the clamp is moved to the closed position. The user may support the instrument case in two hands while depressing the sliding clamp member to permit the clamp members to be positioned around a pole. When the pressure is released, the spring causes the clamp to close on the pole. A camming lever permits the user to provide positive latching of the clamp member from movement, and to engage an anti-rotation element with the pole. An interlock prohibits activation of the camming lever while the movable clamp member is being depressed.
