    摘要: A flow controller primarily for breathing gas analysis has a gas flow circuit leading from a breathing air inlet to a gas analyzer and to a vacuum source. Another gas is bled into the circuit between the breathing air inlet and a point upstream of the vacuum source. Such other gas is precluded from flowing upstream in the circuit toward the gas analyzer by making the intervening flow path or conduit of suitable dimensions to have a Peclet number at least equal to 4 and preferably greater than 4 and about 6.

    摘要: This invention provides a simple skeletal muscle linear pull energy convertor which can harness the maximal amount of muscle power for a wide variety of implantable medical devices, including the full range of circulatory support devices. The muscle powered system provides completely implantable circulatory support as an alternative to cardiac transplantation, with a quality of life relatively free from external batteries, transcutaneous energy transmission and other electromechanical hardware.

    摘要: A volume ventilating respirator, especially for infant and pediatric use, has a pair of different size volume chambers with means for selecting one or the other for specific use. There is a selector affording a choice of several different ventilating modes including deep breaths at chosen periods or events. The operation is generally automatic with response to patient effort, if desired, and has some responses to manual signals; i.e. deep breath and inspiration. The operation is electric with pneumatic and electronic controls and logic and numerous event indicators and alarms.
