  • Patent number: 6110410
    Abstract: A method of radio frequency (RF) welding of a flexible PVC sheet to a rigid copolyester carrier by holding a flexible PVC sheet and a rigid copolymer carrier together between heated RF dies. A predetermined temperature differential is maintained between the RF dies, with the flexible sheet side at a higher temperature than the rigid carrier side and adjusted so that a weld plane is established along the interface between the PVC and the copolyester. An RF weld signal is passed through the first and second RF dies and the PVC and copolyester therebetween, so that the flexible PVC sheet and the copolyester rigid carrier partially melt and become welded together at the weld plane.

  • Patent number: 5554013
    Abstract: A fluid infusion pump includes a disposable cassette having an inlet, an outlet, and a fluid chamber between the inlet and the outlet. There is a fixed wall of the fluid chamber and a movable wall of the fluid chamber. A pump body receives the cassette in a fixed operating relationship such that an actuator in the pump body is activatable for reciprocal advancement and retraction with respect to the cassette and is adapted to confront the movable diaphragm when the cassette is received in the pump body. There is a detachable coupling between the actuator mounted in the pump body and the movable wall so that fluid is expelled from the fluid chamber on advancement of the actuator and positively drawn into the fluid chamber upon retraction of the actuator.

  • 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.
