    Abstract: A fluid infusion pump includes a platen between an outer door and the pumping mechanism. The platen is located so that as the outer door of the pump is moved to the closed position, it moves the platen to position the fluid flow tube into occlusive contact with the pumping mechanism before the platen engages a flow stop formed integrally with the tube and releases the flow stop to permit fluid flow, thus avoiding a free flow condition. The door also includes a handle having a sear with a hook that engages the flow stop when the door is in the closed position. As the door is opened, the hook moves the flow stop to the occluded position before the platen is moved away from the tube thus preventing a free flow condition. The platen includes a flow stop release portion that is offset from the remainder of the platen that operatively engages a release tab on the flow stop to permit movement of the flow stop to the fluid flow configuration. The platen is mounted to the housing with a floating hinge and datum pins located on the face of the pumping mechanism precisely locate the platen into position with the pumping mechanism and thereby result in precise positioning of the fluid tube.

    Abstract: A syringe plunger driver system capable of capturing syringes of widely varying sizes comprises a pair of asymmetric plunger retainer arms pivotally mounted to a plunger driver. The system includes a low profile driver having a length that exceeds its width so that it may be mounted adjacent control modules and other operational modules. The arms are biased toward each other and one arm is longer than the other with a notch on an inside edge to receive the tip of the shorter arm when capturing small syringe flanges. A rotation knob mounted to the front surface of the low profile driver forces the arms apart when rotated to a first rotation position. A force sensor is mounted in the driver to detect occlusions in the fluid line. A processor monitors the force sensed by the force sensor and provides an alarm if the force exceeds a threshold. The driver includes a force concentrator that defines a pushing surface adapted to press against a plunger flange so that the force applied to the plunger flange is concentrated at a defined location for more accurate measurement.

    Abstract: 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.
