METHOD FOR PREPARATION AND SUPPLY OF THERAPEUTIC GAS MIX AND DEVICE FOR ITS EMBODIMENT Russian patent published in 2000 - IPC

FIELD: medical devices, in particular, for curing, first aid, rehabilitation after surgery, and so on. SUBSTANCE: method involves proportioning and mixing compressed gases, their heating and adding inhalation doping agents and subsequent processing in recycling mode with oxygen additions. Gas mix is supplied as either atmospheric air or as prepared gas mix of specific content. Inhalation doping agents are added by means of blowing heated gas mix through inhalation materials. Prepared mix is used as gas mix for breathing using inhalation mask or as gas environment in helmet, intensive treatment unit or under local cover. Corresponding device has inhalator, which is embedded into mix chamber, which is located in gas channel between therapeutic tank and gas heater, which is designed as controlled transmission-type heat exchanger. Output unit may be designed as inhalation valve which is connected to air or be connected to additional gas mix flask, which has reduction valve and constrictor, or to additional oxygen flask. Main gas channel between gas mix flask and heat exchanger may include forced breathing bellows or compressor with periodic action receiver and maximal pressure reduction unit, which are equipped with single turn gas mix supply and regulators of rate and speed of its actuation. EFFECT: increased efficiency of inhalation. 21 cl, 5 dwg
