Title: Individual respiratory gas supply device including a respiratory mask and a facial respirator

Abstract: Individual respiratory gas supply device comprising a respiratory mask and a facial respirator of the cannula or respiratory flexible oro-nasal shell type for comfortably supplying a subject with respiratory gas during a high-altitude flight. The respiratory mask and the facial respirator are adapted so that in the event of de-pressurization or the presence of toxic gases, the subject equips himself with the respiratory mask possibly after having previously removed the facial respirator. Switching means make it possible to cut off the oxygen supply of the facial respirator and dispense oxygen to the regulator when the subject is equipped with the respiratory mask.
