  • Patent number: 9283370
    Abstract: An infusion pump for metering fluid flow through an delivery tube of an infusion tubing set has an internal occlusion clamp which clamps the delivery tube to prevent the free flow of fluid through the tube when access to the delivery tube in the infusion pump is possible. To release the delivery tube from the infusion pump, a slide clamp is manually used to release the occlusion clamp to an open, non-occluding position while simultaneously occluding the delivery tube to prevent the free flow of fluid.

  • Patent number: 9017297
    Abstract: A delivery tube is inhibited from unintended withdrawal from an infusion pump which has an internal occlusion clamp that clamps the delivery tube to prevent the free flow of fluid through the tube, by overlapping a blocking lip from a compression edge of the occlusion clamp with a restraint surface of an anvil against which the tubing is compressed and by overlapping a blocking projection from the restraint surface with the compression edge. Inhibition is also achieved by positioning an obstruction protrusion adjacent to the compression edge and the blocking lip to resist the application of exterior physical force to force the occlusion clamp from an occluding position to a non-occluding position.

  • Patent number: 7914490
    Abstract: An ambulatory infusion pump assembly and housing therefore has a cover and a base providing an enclosed cavity. The system includes a liquid pump in fluid communication with a supply source of a liquid drug. The pump and supply source are received in the housing cavity. Further, the system includes a seal providing a liquid tight seal between the cover and the base. A through passage extends from the enclosed cavity external to the housing and an infusion tube extends through the through passage. A fluid tight seal is formed about the infusion tube. A vent is provided in the housing that maintains a balanced pressure state between the enclosed cavity and the atmosphere, while at the same time, the vent prevents the ingress and egress of contaminants into and fluid out of the enclosed cavity.
