摘要： An interlock, latching and retaining mechanism for use in an infusion system, embodying a latch arm mounted to a rotatable shaft having a plurality of cams and gears attached thereto, a rectangular faceplate with a pluraltiy of apertures formed therethrough, and a clamp. Rotating the latch arm functions to engage fluid monitoring, flow control and pumping structure of the infusion system with a pumping segment for control of fluid flow through the segment and also causes the clamp to hold the pumping segmemt in a required position. In another aspect, rotation of the latch arm additionally causes an air-in-line sensor to rotate into position on the pumping segment.

摘要： An interlock, latching and retaining mechanism (10) for use in an infusion system, embodying a latch arm (28) mounted to a rotatable shaft (26) having a plurality of cams (146, 148) and gears attached thereto, a rectangular faceplate with a plurality of apertures formed therethrough, and a clamp. Rotating the latch arm functions to engage fluid monitoring, flow control and pump structure of the infusion system with a pumping segment for control of fluid flow through the segment in a required position. In another aspect, rotation of the latch arm additionally causes an air-in-line sensor to rotate into position on the pumping segment.

摘要： An air-in-line sensing apparatus (10) for use with a parenteral fluid administration set (34) to detect the passage of air through a fluid conduit (12). The apparatus comprises a first housing having a first arcuate section mounting a first transducer adjacent the first arcuate section and a second housing having a second arcuate section mounting a second transducer adjacent the second arcuate section. The first and second housings are independently movable relative to each other so that when the housings are moved towards one another, the first and second arcuate sections capture a length of administration set tubing therebetween (44) providing secure intimate contact therewith. A signal may be generated from one of such transducers, passed through the fluid conduit and received by the other transducer to detect whether the conduit is carrying air.

摘要： A fluid delivery system in which the pressure platen for a fluid conduit is fixedly mounted to the pump and the pumping mechanism is movable in relation to the platen (32) to control the force exerted on the conduit. A moving system comprising a four-bar linkage (48, 50, 52, 54) retains the movable pumping mechanism in a predetermined orientation to the conduit through the mechanism's range of movement. The pumping mechanism is spring (63) loaded towards the conduit (30). The peristaltic fingers (22) of the pump mechanism are located in guides with the drive means for those fingers rigidly mounted to that guide. Should the movements of one or more fingers through the respective guide be prevented, the drive means will be stopped from movement and the pumping mechanism will stall rather than back off and allow free flow.
