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: IMPLANTABLE INFUSION DEVICE Multiple embodiments of an implantable infusion device for delivering precisely regulated dosages of drugs are disclosed, 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.

Abstract: A method and apparatus for analyzing pulmonary function including diffusing capacity and cardiac output or local pulmonary blood flow while necessarily determining alveolar volume in order to complete the abovenoted analysis. In order to provide a rapid response in each of the abovenoted analyses or determinations, appropriate gases are caused to be inhaled and exhaled through a sample cell wherein a percentage of each gas may be constantly monitored during inhalation and exhalation by means of non-dispersive infrared absorption techniques, the sample cell and associated components of the pulmonary function analyzing device including additional features to facilitate the abovenoted analyses and determinations, the combination of gases employed for monitoring the pulmonary functions being selected to permit accurate detection by infrared absorption techniques.
