International Classification:

A62B 708

US Classification:

128147

Abstract:

A cannister has an inhalation chimney mounted thereon, and includes an inlet and an outlet. Several layers of KO. sub. 2 particles are contained in the cannister, separated by parallel screen assemblies, the upper two screen assemblies being connected by a vertical bypass screen near the cannister inlet. The layered KO. sub. 2 bed is effective to remove CO. sub. 2 from exhaled breathe, and generate oxygen for recharging the air prior to inhalation. The cannister inlet is connected by a flexible hose to the exhalation side of a breather mouthpiece, the inhalation side of the mouthpiece being connected to the upper end of the inhalation chimney. Communication between the cannister outlet and the lower end of the inhalation chimney is provided by a breather bag, fitted with a set of baffles to define a tortuous flow path for cooling the processed air. A collector mounted at the cannister outlet prevents liquid KO. sub. 2 from entering the breather bag.

International Classification:

A62B 708

US Classification:

128147

Abstract:

An impact resistant external casing is provided to enclose a canister containing a multi-layered chemical bed, with by-passes in each layer to accommodate the flow across and through the bed of exhaled breath which reacts with potassium superoxide in tablet form, the casing being provided with a (top) lid section which contains a mouthpiece, breathing hoses, and neck straps, the opposite side of the casing being provided with a bottom cover which accommodates the storage of a folded breathing bag and chest straps. An air passageway constituting an annular section is provided to accommodate a chimney extending from the bag through the passageway section between the casing and the canister, which is open to ambient air for cooling purposes. The inside bottom portion of the canister is provided with a trammel to prevent escape of deliquesced KO. sub. 2, and the breathing bag is characterized by having a single baffle, forcing air through the bag in such manner as to take the air as far from the heat of the canister as is possible.
