Abstract: An infusion device includes an infusion pump for delivering a liquid through an infusion conduit from a separate source of the liquid into a patient, a bubble detector for detecting the presence of an air bubble in the infusion conduit, and control circuitry responsive to the bubble detector for determining if the size of the air bubble is unacceptable. The control circuitry is configured to determine if during the time the air bubble is detected it advances a distance indicative of the unacceptable size, one embodiment counting the steps of a linear peristaltic infusion pump for that purpose.

Abstract: A dispenser comprising a base and a reel rotatably mounted on the base. An elongated flexible member which is to be dispensed is wound on the reel, and a housing is provided for the reel and the flexible member. Interlocking members on the reel and the housing hold the reel against rotation in the housing. The reel has first and second sets of radially extending fingers at the periphery of the reel, with the first set of fingers being inclined relative to the second set of fingers. The flexible member is wound on the reel between the first and second sets of fingers.

Abstract: A clamp apparatus useful for controlling the flow of fluid through a flexible conduit which comprises: a resilient pad element adapted to aid in at least partially occluding the conduit; and a force system structured to be moved to at least partially occlude the flexible conduit such that when the force system is activated the flexible conduit contacts both the resilient pad element and the force system and the resilient pad element moves in response to the activation of the force system, provided that the force system is adapted to maintain the flexible conduit in at least one state of partial occlusion.
