    摘要： An ambulatory infusion system includes a spring-pressurized reservoir to facilitate portable use of the system. The system includes a liquid-filled flexible container, and a pair of opposed platens between which the flexible container is removably positionable. Energy-storing, clip-like biasing springs act against the platens to urge them toward each other, thereby effecting pressurization of the liquid within the container. A tubing set of the system preferably includes a non-adjustable flow restrictor, which may be sized for relatively low flow rates to permit the system to be used for catheter patency maintenance.

    摘要： In an apparatus for testing pneumatic flow resistance of a test component, such as an air filter useful in a system for admixing parenteral solutions, a pneumatic bridge has two branches connected, via a filter, a flow restrictor, and a flowmeter, to a source of gas under regulated pressure. Each branch comprises two arms with a centerpoint. The bridge has a pressure transducer connected between the centerpoints and arranged to detect pressure imbalances in the bridge. Each arm comprises a flow restrictor, namely a needle valve, which is calibrated via a vernier head. The valves are adjustable to balance the bridge. In one arm, in which the needle valve can be fully opened, the test component is connectible to constitute a flow restrictor. The transducer produces an output displayed via a digital voltmeter, which may be calibrated.

    摘要： A method and apparatus are provided for controlling the dispensing of a primary liquid from a pressurized source of primary liquid. Primary liquid is admitted through an inlet valve to a primary chamber having a primary element which is biased toward an initial position but is movable away from the initial position when subjected to the source pressure of the primary liquid. A sensor determines when the primary element has moved away from an initial position to a predetermined final position, and the inlet valve is closed in response thereto. The difference between the initial and final positions defines a predetermined dispensing volume. An outlet valve is opened to dispense the dispensing volume under the biasing force of the primary element which returns to the initial position. A sensor determines when the primary element has returned to the initial position, and the outlet valve is closed in response thereto.

    摘要： A catheter assembly with a reciprocable obturator is disclosed which facilitates patency maintenance during intravenous therapy. The assembly includes a catheter having an elongated tubular portion defining a lumen, and an obturator assembly mounted on the catheter. The obturator assembly includes a reciprocable obturator member including an elongated obturator rod telescopically disposed within the catheter lumen. The rod is configured to cooperate with the lumen to inhibit liquid flow into the free end of the catheter. The device can be employed in conjunction with a high molecular weight, viscous fluid, in order to further inhibit ingress of liquid into the catheter.
