RESPIRATORY APPARATUS TO PERFORM CLEANING OF GAS MEDIUM IN HERMETIC OBJECT

摘要

FIELD: mechanics. ^ SUBSTANCE: respiratory apparatus to perform cleaning of gas medium in hermetic object consists of face part and absorbing cartridge with carbon dioxide as absorber; face part and absorbing cartridge are connected to each other with a hose pipe. Absorbing cartridge is equipped with an absorber on lithium hydroxide base, the said absorber cartridge is made as perforated blocks. Inhale valve is located directly in the face part or in the hose pipe. Exhale valve is installed into the hose pipe between the inhale valve and the absorbing cartridge creating a free volume of 100-300 cubic cm between the face part and the inhale valve. Exhale branch is installed in the lower part of the absorbing cartridge at the outlet to the hermetic object. ^ EFFECT: to increase efficiency of gas medium cleaning in a hermetic object due to reduction of exhale resistance and utilization of physiological characteristics of a human organism of members of the crew of a hermetic object. ^ 2 cl, 1 dwg
