Abstract

A diver's breathing apparatus comprises a mouthpiece, a canister of carbon dioxide absorbing medium, two tubes linking the mouthpiece and the canister, one permitting flow of exhaled gas to the canister and the other permitting flow of purified gas to the mouthpiece. Two more tubes extend between the canister and an inflatable bag. One allows gas to flow into the bag and the other allows gas to flow back to the canister. The apparatus further comprises a high pressure oxygen cylinder to maintain a sufficient oxygen concentration in the system. Non-return valves in said tubes ensure that virtually all exhaled gas passes twice through the canister before being rebreathed.
