Abstract:
1. An individual respiratory gas supply device comprising a respiratory mask for supplying a subject with respiratory gas, especially during a high-altitude flight, the mask itself comprising an oro-nasal facepiece adapted for covering the mouth and nose of the subject, thereby providing a substantially leaktight junction with the face of this subject, the facepiece being connected to an oxygen flow regulator supplying the facepiece with respiratory gas from an oxygen dispenser, comprising: a facial respirator adapted for delivering oxygen to at least one of the oro-nasal orifices of the subject without preventing inhalation of ambient air when the subject inspires, and means of switching the dispensing of oxygen between the respiratory mask and the facial respirator, adapted for cutting off the oxygen supply of the facial respirator and dispensing oxygen to the regulator from the dispenser when the subject wears the respiratory mask.
