    摘要： A medical pump apparatus including an internally sterile pumping chamber having a flexible diaphragm forming a wall portion and a drive rod extending through the diaphragm in a rotating vane disposed within the pumping chamber. A motor rotates a revolving hook which engages the drive rod to drive the vane within the pumping unit. The pumping chamber is isolated from the motor by the fluidtight attachment of the drive rod through the flexible diaphragm. Fluid is pumped into the inlet of pumping chamber through the hollow shaft of the vane and out through a fluid conduit of the vane, subsequently out the outlet of the pumping chamber.

    摘要： A normally-closed valve that can be easily connected and disconnected. Disposed in the fluid passageway through the valve is a flexible, resilient disk and a pin mounted adjacent to the disk. The disk is mounted in a wide portion of the passageway and is held in place by the narrow portions of the passageway. The disk fits snugly into the passageway so that the edge of the disk forms a seal with the wall of the passageway. A nozzle is inserted into the passageway and urges the pin against the disk, causing the disk to deform. When the disk deforms, its effective diameter decreases, and its edge separates from the passageway wall, permitting fluid to flow through the valve. The narrow sections of the passageway wall have channels disposed therein for permitting flow when the disk is deformed. The pin also has channels on its surface to permit flow around it.

    摘要： A system is provided for the automatic, self-checking switching of a medical infusion controller among a plurality of modes of operation. A medical infusion controller has a plurality of pressure-sensitive switches, each of which corresponds to a different mode of operation. A drip chamber is provided with nub elements in one of a variety of possible configurations, each of which correspond to one of the pressure-sensitive switches on the controller. When the drip chamber is placed in the controller, the nub configuration activates the corresponding switch. If the controller detects an incorrect number of nubs, it delivers an error message.

    摘要： A system for measuring flow of fluid through a line. A portion of the fluid in the line is isolated in a rigid container so that the fluid in the container is not affected by pressure in the rest of the line. An apparatus is provided for measuring that portion of the container that is not occupied by the fluid. In order to urge fluid into and out of the container, a positive pressure source, for providing gas to the container, and a negative pressure source for removing gas from the container, are provided for.

    摘要： A system detecting the presence of successive drops of fluid in a fluid path has a system input for connection to a photoelectric transducer so situated as to have a change in electrical output on the presence of a drop in the fluid drop path. The system includes an arrangement for storing a quantity related to the value of the photoelectric transducer output in the absence of a drop. The quantity stored can then be compared with the present value of the output of the photoelectric transducer, and in the event of a sufficient difference, an output may be provided. In a preferred embodiment, the output signal itself may be used to disconnect the storage system from receiving input information that pertains to the presence rather than the absence of a drop.

    摘要： A sheet with inlet and outlet ports forms a housing, with a flow tube disposed between the ports. In a preferred embodiment, a plurality of arms affixed at one end to the housing are adjustably spaced by a threaded tapered nut which mates with the other end of the arms. The flow tube passes between the arms and is constricted by the arms as the nut is advanced. The thread pitch, the degree of taper, and the point where the tube crosses the arms all determine the rate of constriction. In a further preferred embodiment the tube passes through a transverse indentation in the arms and is bonded thereto. In another preferred embodiment the housing is adapted to removably mount on an automatic flow sensing and adjusting module, which engages the tapered nut to adjust the flow rate through the tube.

    摘要： In a system for controlling fluid flow from a reservoir to a patient, a first signal representative of reservoir weight and a second signal representative of desired weight are compared digitally to generate a signal representative of their dissimilarity. An analog strain gauge may be used together with an analog-to-digital converter for generating the reservoir weight signal.

    摘要： A device for reducing the rate of flow from a reservoir as the reservoir empties requires only a single chamber having an input, for receiving fluid from a reservoir, and an output port. There is a provision for sensing fluid level in the chamber, and a separate provision for reducing the flow through the output port when fluid level in the chamber has fallen to a predetermined level. In a preferred embodiment of the invention, fluid level is sensed by a float, which, after falling to a predetermined level, actuates a plunger that reduces flow through an aperature at the bottom of the chamber.
