  • Intermitten gas-insufflation apparatus and method therefor
    Patent number: 5735268
    Abstract: An intermittent gas-insufflation apparatus insufflates a quantity of the gaseous fluid into an entrance of a respiratory system of a breathing patient during an exhalation interval of an immediate breathing cycle and into a subsequent inhalation interval of a successive breathing cycle. The intermittent gas-insufflation apparatus includes a valve assembly, a sensor and a controller. The valve assembly actuates between a closed state to prevent the gaseous fluid from flowing from a source of gaseous fluid to the patient and an opened state to establish gaseous fluid flow to the patient. The sensor detects changes in breathing pressure of the patient throughout the immediate breathing cycle and to generates sensor signals characteristic of the changes in the breathing pressure thereof.
    Type: Grant
