    Abstract: A pump is described in which a flexible enclosure defines a pump chamber and in which the contents of the pump chamber are expelled by movement of a pair of opposed pusher elements engaged with the enclosure. The pusher elements are displaced by at least one pair of beam springs, each of which is pivotally supported at one end and is engaged with one of the pusher elements at the other end. The ends of the beam springs opposite the pusher elements are pivoted by actuation of symmetrical solenoid armatures, causing each of the springs to be stressed. Relief of the spring stress forces the pusher elements toward each other. De-energization of the solenoid armatures permits the beam springs to pivot back to the original position upon filling of the pump chamber.

    Abstract: Multiple embodiments of an implantable infusion device for delivering precisely regulated dosages of drugs, each device including reservoir means (16) for containing the drug, catheter means (22) for delivering the drug to the body and an actuating means (44) which is responsive to a signal applied externally of the body for initiating delivery of a precisely regulated dosage. In one embodiment, the device is implanted subcutaneously to permit actuation by a solenoid driven element responsive to coded telemetry signal applied through the skin. In additional embodiments, the reservoir is pressurized for example, by means of vapor pressure or a mechanical spring, the drug under pressure in the reservoir being released in response to an externally applied signal.

    CPC classification number: G01N21/3504

    Abstract: A gas analyzer and gas analyzing method are described of the non-dispersive infrared type wherein infrared energy is passed through a sample cell (11) containing an unknown mixture of gas. The infrared energy passing through the cell is received by a detector (13) and an electrical signal is produced representative thereof. A rotary filter wheel (15) positions at least one filter (16) in the path of the infrafed energy, resulting in a pulsating detector output. The electrical signal is processed to produce an output indicating the concentration of the constituents of the gas mixture in the sample cell. Synchronization with the processed electrical signal is obtained by deriving synchronizing pulses directly from the electrical signal produced by the detector.

    Abstract: An apparatus and method for measuring the concentration of carbon dioxide in respiratory gases. The apparatus is a non-dispersive gas analyzer (100) attached in series with the respiratory airway which is universally compatible with any host system. The analyzer (100) includes a housing (102) which supports a sample cell containing the respiratory gases, and which contains an infrared radiation source (130) encased in shock absorbing material, means for directing the radiation into a collimated beam through the sample cell, means (145) for splitting the beam and directing it towards two infrared detectors (142, 146) for measuring the amount of absorption of carbon dioxide in the sample cell. The analyzer has two heating servos (118, 152), one regulating the temperature of the sample cell windows to inhibit condensation build-up and one regulating the ambient temperature surrounding the detectors (142, 145) to ensure more accurate measurements. Calibration means within the analyzer housing ( 102) stores and provides information characterizing performance parameters of the analyzer (100).
