Mask carbon-oxygen exchange type spontaneous respirator and method for manufacturing same

Abstract

The invention discloses a mask carbon-oxygen exchange type spontaneous respirator which comprises an open mask, an air chamber, a reaction chamber, a reaction chamber connecting sleeve and an exhalation guide tube. Gas is distributed by the aid of three partition plates with check valve plates, the partition plates are arranged above the air chamber, gas only can flow out of a center check valve but cannot flow into the center check valve, exhaled gas is directly guided into the reaction chamber via the exhalation guide tube, the reaction chamber in the special design is of a double-layer structure, the exhaled gas reacts to metal superoxides which are placed in a layered manner, the exhaled CO<2> is adsorbed to generate solid K<2>CO<2>, O<2> can be released, gas with the sufficient oxygen escapes from a porous cover of the reaction chamber, flows into the air chamber and is inhaled into the respiratory organs of a user via two check valves, and gas only can flow into the two check valves but cannot flow out of the two check valves. The mask carbon-oxygen exchange type spontaneous respirator has the advantages that the shortcoming that respiration oxygen needs to be generated by the aid of oxygen candles in advance due to carbon-oxygen exchange reaction lag of a mixed-flow respirator can be overcome, the spontaneous oxygen supply respirator is small, the user can wear the spontaneous oxygen supply respirator conveniently and can be prevented from being harmed by toxic fume, and the mask carbon-oxygen exchange type spontaneous respirator can be used as an emergency oxygen supply tool under the condition of oxygen deficiency.

Description

technical field [0001] The invention relates to a mask-type carbon-oxygen exchange self-breather with diverted exhalation and inhalation and a preparation method thereof. The respirator is a device used for escaping in a fire and belongs to fire-fighting equipment. Background technique [0002] According to statistics, more than 80% of the people who died in the fire were smothered to death by toxic smoke, and less than 20% were directly burned to death. Therefore, how to prevent being smoked to death is one of the important measures to reduce the number of fire deaths. It is understood that the fire department has required hotels, guesthouses, entertainment venues and other crowded places to be equipped with anti-smog equipment. But, the anti-smog equipment for above-mentioned unit application mainly contains two kinds on the market at present: a kind of is the filter type respirator that filters harmful substances with active carbon adsorption; Another kind is the self-ox...
