Description
The utility model relates to a kind of chemical oxygen self-rescuer as the mine rescue device.
Existing chemical oxygen self-rescuer is given birth to the keto consumpting speed of oxygen speed less than the people owing to give birth to the initial stage of oxygen medicine, thus the starter gear of using for living oxygen of initial stage all is housed, with underwriter's physiology of respiration requirement.After the product of prior art has been installed starter gear, reduced reliability, the security used, made volume increase, complex structure, the cost up of self-rescuer.The reciprocating type breathing gas circuit that some self-rescuer adopted, temperature height during expiration, comfortableness is poor.The vent valve of some self-rescuer is individual layer or baroque bilayer, and the security of individual layer vent valve is relatively poor.
The purpose of this utility model is, designs a kind of chemical oxygen self-rescuer that does not have starter gear, has simple in structure, dependable performance, the comfortable characteristics of use.
The technical solution of the utility model is that on the prior art architecture basics, the people's breath inlet end in medicinal cupping is loaded onto the startup oxygen producing drug layer.Wherein one two-port in the breathing catheter group that is made of two root breath conduits is installed sniff valve, to form circulating respiratory system.Also the longest dimension of breathing catheter group can be designed to be not more than the diameter of medicinal cupping; Vent valve on the air bag is designed to have the double-deck vent valve of two-layer rubber valve plate, in medicinal cupping, adopts the hydroxide flake lithium as carbon-dioxide absorbent; And adopt custom-designed gas leakage indicator.
Below in conjunction with drawings and Examples the utility model is explained.
Fig. 1 is the concrete structure of an embodiment of the present utility model, breathing catheter group, gas leakage indicator that it comprises medicinal cupping (8), mouthful tool (2), air bag (15), is made up of breathing catheter (26) and (5), vent valve (22) is housed on the air bag (15), its design feature is that human body expired air inlet end is equipped with and starts oxygen producing drug layer (10) in medicinal cupping (8).
Referring to Fig. 1 and Fig. 2, in the breathing catheter group by breathing catheter (5) and (26) formation, described breathing catheter (5) is communicated with medicinal cupping (8) by ventilation gum cover (7), and breathing catheter (26) is communicated with air bag (15) by air bag attachment cap (16).The utility model is equipped with sniff valve in the two-port of breathing catheter (26).Described sniff valve is made of valve seat (25) and valve block (24).In order to make device that smaller volume be arranged, the longest dimension of described breathing catheter group can be designed to be not more than the diameter of described medicinal cupping (8).
Referring to Fig. 3, the vent valve (22) on the described air bag (15) comprises valve seat (31) and valve gap (32), and its design feature is that it is equipped with interior valve block (30) and the external valve plate made from rubber (29).Its work characteristics is, inlet air pressure is opened valve block, and after air pressure was reduced to certain value, valve block relied on the elastic force of self to reset.
Can in medicinal cupping, adopt the hydroxide flake lithium, make its absorbing carbon dioxide better, and be difficult for producing dust.
Referring to Fig. 4, can go up at self-rescuer shell (36) special gas leakage indicator is installed, it is by transparent telltale shell (33), indicator box (34) and place the indicator (35) of described box (34) to form, and between self-rescuer shell (36) and indicator box (34) two sealing-rings (37) is arranged.Its design feature is that described transparent telltale shell (33) has the garden arc-shaped outer surface of projection, and can adopt thread connection between described shell (33) and self-rescuer shell (36), is convenient to assembling.
Optional usefulness following three kinds (weight percent) is formed in the reference of described startup oxygen producing drug layer (10):
A, sodium superoxide or potassium superoxide 56-92.8%, boric acid 30-5%, aluminium powder 1-0.2%, manganous sulfate 8-2%, copper hydroxide 5-0.5%.
B, sodium superoxide or potassium superoxide 56-92.8%, borax 30-5%, aluminium powder 1-0.2%, manganous sulfate 8-2%, copper hydroxide 5-0.5%.
C, sodium superoxide or potassium superoxide 56-92.8%, monohydrated sodium carbonate 30-5%, aluminium powder 1-0.2%, manganous sulfate 8-2%, COPPER OXYCHLORIDE 37,5 5-0.5%.
The reaction principle that starts oxygen producing drug layer is, it at first touches people's expired air in medicinal cupping, its carbonic acid gas and aqueous vapor make super-oxide give birth to oxygen and give birth to heat, make aluminium powder oxidation emit a large amount of heat simultaneously, make dehydration material (as boric acid) dehydration, thereby make super-oxide emit a large amount of oxygen, satisfy the requirement of use initial stage oxygen-consumption.Manganous sulfate and COPPER OXYCHLORIDE 37,5 play catalyst action.
Principle of the present utility model is, the human body expired air enters ventilation gum cover (7) through the breathing catheter group, enter medicinal cupping (8) again, make its carbonic acid gas of giving birth to oxygen and absorbing exhalation with drug reaction in the jar, the oxygen that generates in jar enters air bag (15) through medicinal cupping lid (19) and air bag attachment cap (16); When air-breathing, the oxygen in the air bag (15) arrives a mouthful tool (2) through sniff valve and breathing catheter group, enters human body, forms circulating breathing gas circuit thus.If the interior oxygen of medicinal cupping (8) generates too much, air bag (15) internal gas pressure is increased, then this air pressure is opened the double-deck valve block of vent valve (22), discharges too much oxygen, and underwriter's eupnea needs.The double beat valve chip architecture of vent valve (22) is simple in structure, safe and reliable than prior art.Lithium hydroxide is absorbing carbon dioxide better, and its sheet structure can reduce the generation of dust.Then variable color of indicator contact moisture in the gas leakage indicator shows the self-rescuer shell gas leakage of sealing, and shell (33) can protect inner indicator lid (34) not to be damaged, and its protruding garden arc-shaped outer surface makes shell (33) that better intensity be arranged.Adopt thread connection between telltale shell (33) and the self-rescuer shell (36), make assembling, easy to maintenance.
The utility model has been cancelled starter gear, has simplified the self-rescuer structure, has improved the reliability and security that uses, its volume compact, and circulating breathing gas circuit makes low, the comfortable wearing of suction temperature; Exhaust structure is simple, safe and reliable, and the hydroxide flake potassium of absorbing carbon dioxide is difficult for producing dust; Gas leakage indicator is simple in structure, and intensity is preferably arranged, and is convenient to assembling and maintenance.
