Abstract
860,756. Respiratory appliances. FRANCAIS ETAT. Feb. 6, 1957 [Feb. 27, 1956], No. 4178/57. Class 81 (2). In a closed circuit oxygenbreathing apparatus the exhaled air is passed through soda-lime, oxygen is added and it is then inhaled. As shown, Fig. 4, A flexible bag 3 deflates upon inhalation through valve 13 and opens the oxygen supply valve 8, by lever 9, to supply oxygen from bottle 1 to the purified exhaled air. Upon exhalation, through valve 14 and filter 16, the used air is forced through soda-lime, in purification chamber 2 into the inhalation chamber 11, together with oxygen admitted during inhalation. The apparatus is mounted on a semi-flexible covering, not shown, which holds the apparatus clear of the chest of the wearer.
