Abstract
A breathing assisting device. The device includes a face mask and an oxygen dispenser which alternately injects oxygen (i) into the mask during an inhalation phase, and (ii) into a conveying piece which in turn conveys the oxygen through the mask during an exhalation phase in a manner which produces a subatmospheric pressure, or suction, within the mask during the exhalation phase, thereby assisting the user with both inhalation and exhalation.
