    Abstract: Multiple embodiments of an implantable infusion device for delivering precisely regulated dosages of drugs are disclosed, each device including reservoir means for containing the drug, catheter means for delivering the drug to the body and an actuating means 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.

    Abstract: An intravenous and intra arterial delivery system is described having a disposable cassette actuated by a pump and control electronics for providing positive but variable delivery rates. The cassette is self-priming and provides protection against the delivery of air by being unable to impel air, and means provide an indication of excessive air in the cassette. The electronics has low power consumption so as to be suitable for battery operation, such as by way of rechargeable batteries. A pressure sensor in the delivery line may be used to sense infiltration. The system further features a provision for predetermining the amount of fluid to be delivered, and a detection system for detecting an empty supply bottle.

    Abstract: A non-dispersive infrared gas analyzer utilizing a fluorescent source including a specific gaseous compound whose presence in an unknown gas mixture is to be detected and a container having infrared transparent portions. Fluorescent emission from the specific gaseous compound is stimulated by, for example, a black body infrared source. A sample cell retains an unknown gas mixture in a position to receive fluorescent emission so stimulated while a suitable detector or transducer detects energy absorption by the unknown gas mixture of substantially any portion of the fluorescent emission spectrum of the gaseous compound being detected. An additional stage of selectivity is obtained by inserting a fluorescent filter between the sample cell and the detector. A standard for comparison is provided by a two-channel gas analyzer utilizing a standard cell or normalizing cell in addition to the sample cell. A standard for comparison is also provided by including in the fluorescent source a gaseous compound and enriched quantities of one or more isotopes of the gaseous compound to provide different but nearby wave lengths. A variety of arrangements for signal chopping and for shielding the black body infrared source from the sample cell is included.

    Abstract: An arrangement for ensuring the stability of the set point for a gas analyzer is disclosed. The set point control circuit utilizes an amplifier which is alternately switched between a reference voltage and a sensor signal to provide a signal to a processor representing the reference signal and the sensor signal. The processor compares the two signals and adjusts the heater associated with the sensor to provide a stable set point for the gas analyzer. The arrangement eliminates the need for precision resistors within the set point control circuit and therefore significantly reduces the cost of the circuitry.

    Abstract: An adaptor assembly is described for sampling gas in an airway tube attached to a patient. The adaptor assembly employs a filter arrangement in a subassembly which extends transversely of the axis of the patient's airway and maximizes the ratio of the effective filter area to the dead volume added by the adaptor assembly to the sampling system.
