Steady insufflation of a gas starts before the beginning of each inhalation, and a pulse-like peak flow insufflation of the gas is superposed on the steady insufflation for a short period of times at the beginning of the inhalation, and the steady insufflation is terminated before the end of the inhalation, so as to improve the inhalation efficiency of insufflated gas extremely.

A breath-synchronized gas-insufflation device, comprising a gas source, a valve means connected to the gas source so as to regulate flow rate and duration of gas flow from the gas source, an insufflating means connected to the valve means so as to insufflate the gas therefrom toward a respiratory system of a living body, a sensor exposed to respiration of the living body and producing electric signals which distinctively indicate inspiratory phase and expiratory phase of the respiration, and an operational controller receiving the electric signals from the sensor and producing such control signals to the valve means that gas insufflation starts before beginning of the inspiratory phase and ends before termination of the inspiratory phase while providing a short pulse-like peak flow of a large amount of the gas in an early stage of the inspiratory phase.
