A self-contained portable personal breathing apparatus that has a casing housing a canister containing an oxygen evolving chemical. The casing is disposed inside a cover which is disposed inside a bag. The cover and the casing form a thermal insulating pocket between them, and with the cover material and the casing material, also made of thermally insulating material, a triple layer of thermal insulation is formed around the canister to protect oxygen produced therein from the heat of reaction of the chemical in the canister. A heat exchanger is situated atop the canister to further cool oxygen before inhalation, and breathing tube extends from the bag to the user for channeling exhaled breath and oxygen.

Oxygen self-rescuer apparatus

A closed cycle respirator includes a breathing bag, the bottom of which is in communication with a canister containing a chemical that binds carbon dioxide and water vapor and liberates oxygen. Inside the breathing bag there is a distributor that guides the regenerated respiratory air flowing up from the canister laterally in the direction of the breathing bag's side walls but keeps that air largely away from the side of the bag that lies against the chest of the wearer. The reason for directing the air through the bag in this manner is to reduce the temperature of the air before it is inhaled again.

Breathing bag for closed cycle respirator

A ring-shape connecting member is disposed in an opening in the bottom of a breathing bag, where it is encircled and tightly engaged by an elastic sleeve secured to the bag around its opening and projecting downwardly out of the bag. A chemical cartridge is provided with an upwardly extending ring-shape flange projecting up into the elastic sleeve in sealing engagement with it, and the top of the cartridge within said flange is provided with an opening communicating with the connecting member.

Respirator

A canister provided with openings for flow of air therethrough contains a chemical that removes water vapor and carbon dioxide from that air and liberates oxygen into it. After a period of time the flow of air through the canister is reversed.
