Description

Life saving helmet

1, technical field

Life saving helmet is to adopt to pass into the carbon dioxide of characteristics of contaminated respiratory droplets and steam to carry out chemical reaction in the capillary chromatographic column being filled with the fixing phase of metal peroxides and be converted into oxygen, maintain the eupnea of people, it is to avoid people death by suffocation and portable lifesaving device of designing under anaerobic environment. It is applicable to individual save oneself from shipwreck, poison, fire, the escape of mine disaster scene. Its technology belongs to personal life-saving appliance field.

2, background technology

Metal peroxides runs into moisture and chemical reaction can be occurred to generate alkaline hydrated oxide and oxygen. The alkaline hydrated oxide generated can absorb acid carbon dioxide and occur to neutralize water generation reaction and carbonate. The water generated runs into metal peroxides can continue reaction generation oxygen. Therefore can utilize metal peroxides can be the required oxygen of human body respiration by the carbon dioxide of characteristics of contaminated respiratory droplets and steam transforming. Adopt capillary chromatography column technology using metal peroxides as fixing phase, using the carbon dioxide of characteristics of contaminated respiratory droplets and steam as mobile phase, behind sufficiently long capillary chromatographic column path, carbon dioxide and steam will be fully converted to oxygen and flow out from capillary chromatographic column end. As long as so there being sufficiently long capillary tube, abundant number of capillaries, the metal peroxides of q.s, it is possible to utilize the carbon dioxide of characteristics of contaminated respiratory droplets and steam to obtain the oxygen meeting human body respiration needs.

Helical form chemical reaction post that life saving helmet is made up of the bundle of capillary tubes having been filled with powdery metal peroxide, head-shield two parts that the O-ring tubular that the tee T of one-way cock, flexible oxygen ball and sponge plug form breathes box and the flexible material equipped with transparent window and sealing ring makes are installed constitute.

Breathe box and be fixed on the mouth and nose position outside head-shield. The air inlet breathing helical form chemical reaction post within box and the tee T arm UNICOM being provided with sponge plug and check valve, the gas outlet of helical form chemical reaction post and another root are provided with the tee T arm UNICOM of sponge plug, flexible oxygen ball and check valve, and the 3rd arm of tee T is through breathing box cover and the breathing mouth UNICOM in head-shield. Adopt bundle of capillary tubes can increase chemical reaction post gas flow, increase the contact area of exhalation gas mobile phase and the fixing phase of metal peroxides in capillary tube, both improve metal peroxides utilization rate, and efficiently reduced again the volume and weight of breathing equipment.The tee T that two arms are separately installed with one-way cock has and carbon dioxide and the steam of characteristics of contaminated respiratory droplets is imported reaction column air inlet and simultaneously close off reaction column gas outlet, and reaction column end gas outlet is opened the function simultaneously closing off reaction column air inlet when human body air-breathing. The oxygen that the flexible oxygen ball of tee T flows out for depot reaction post gas outlet. The sponge plug of tee T is possible to prevent metal peroxides powder to enter in tee T.

Sealed flexible head-shield is easy to use and carries, and can avoid external environment condition harmful gas or liquid inlet nose. The transparent window of head-shield is beneficial to user environment of observation, selects best-effort path. The sealing ring of head-shield is possible to prevent harmful gas or liquid to enter head-shield from cervical region head-shield opening part.
