Breath synchronized gas-insufflation device and method therefor

摘要

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.
