Abstract
The utility model relates to a hypoxia respirator capable of absorbing CO2 by a wet method, which is characterized in that a plurality of air filter sheets are respectively arranged in a front cover and a rear cover, and the rear end of the front cover is sheathed together with the front end of the rear cover; a hook is arranged between a front cover component and a rear cover component, and surfaces at both sides of each air filter sheet are uniformly distributed with dense convex columns and are also provided with a plurality of through holes; after installation, through holes of adjacent air filter sheets are mutually staggered. An air outlet port of a face mask is sheathed with an air inlet port of the rear cover, and the rear end of the face mask is connected with an annular and hollow air cushion; inflation can be carried out to the hollow air cushion by a one-way valve, and the rear cover is provided with two rectangular through holes used for fixing both ends of an elastic clamping belt; the front end of the front cover is provided with a plurality of through holes. When the utility model is in use every time, the hypoxia respirator is eluted by clean water, which enables the surface of the inner part to be under a wet state, and then the mask is used for covering spaces around mouths and noses to form a manual hypoxia environment; additionally, according to the two-film theory of air phase and mass transfer in liquid phase, CO2 which is exhaled by the human body is partially dissolved in water.
Description
Technical field: this utility model relates to the low oxygen inhalation apparatus of a kind of wet absorption carbon dioxide that is used for the hypoxic tolerance training.
Technical background: existing various respiratory organs as aqualung, air filter etc., generally all are to provide competent oxygen for user, and can not cause low-oxygen environment.Yet, need enter the people from Plain of highlands work for those, and pilot, spacefarer etc. adapt to the requirement of low-oxygen environment, must carry out the hypoxia adaptability training at the environment of plains region simulated high altitude hypoxia.In recent years, also adopt mimic hypoxic training, improve athletic anaerobic capacity, but this type of special-purpose hypoxic training equipment is comparatively expensive.Application number is that 02222805.5 utility model patent belongs to a kind of low oxygen inhalation apparatus, and it adopts special-purpose CO
2Absorbent, thereby need periodic replacement, use cost is higher; Its structure is also complicated in addition, and it is bigger than normal that volume and weight still shows, and is not suitable for the general masses and uses.
Summary of the invention: it is littler that the purpose of this utility model provides a kind of volume and weight, uses the low oxygen inhalation apparatus of the wet absorption carbon dioxide convenient, that use cost is extremely low.The purpose of this utility model realizes by following structure: this utility model is a kind of low oxygen inhalation apparatus of wet absorption carbon dioxide, and protecgulum and bonnet inside are installed a plurality of air filter pieces respectively; Preceding cover back-end and bonnet front end sleeve are connected together, and both can rotate mutually, and the label symbol of its mutual alignment of expression is arranged respectively on the outer surface; Between front cover member and the back cover part hook is arranged, the fine and closely woven projection of each air filter piece both side surface uniform distribution, other has some through holes, and the through hole that the adjacent air filter piece in back is installed staggers for it mutually, and the face shield port of giving vent to anger connects face shield rear end connection annular hollow air cushion with bonnet inlet end muzzle, can be the inflation of hollow air cushion by check valve, two rectangular through holes are arranged above the bonnet, be used for fixing the two ends of elasticity cassette tape, the protecgulum front end has some through holes.When this utility model uses at every turn,, make interior surface thereof be in moisture state with the low oxygen inhalation apparatus of clean water drip washing.And then be used for sheltering mouth and nose space on every side, and then form artificial low-oxygen environment.According to the double-film theory of gas phase and mass transfer in liquid phase, the CO that human body is breathed out
2To be partially dissolved in the water.The CO that breathes out in this utility model
2Gas is in decentralized photo, thereby can produce bigger liquid-gas ratio (L/G), helps improving CO
2Absorption efficiency.Experimental result shows, each drip washing in ten minutes once, the low oxygen inhalation apparatus of this structure can be satisfied the demand, and can eliminate because CO
2Excessive concentration and the giddy that causes, untoward reaction such as asphyxia.This utility model face shield rear portion is the annular hollow air cushion, can be the inflation of hollow air cushion by check valve, and wherein the mattress shape designs according to face feature, thereby guarantees to coincide with the closely knit of face.Two rectangular through holes are arranged on the bonnet, the two ends of fixedly connected elasticity cassette tape, thereby very convenient and comfortable when using.Protecgulum and bonnet inside are installed some air filter pieces respectively, and preceding cover back-end and bonnet front end sleeve be connected together, and the two can rotate mutually; Between front cover member and the back cover part hook is arranged, prevent that them from throwing off mutually.Each has some through holes above air filter piece, both side surface evenly has fine and closely woven projection, not only can increase the gas flow resistance but also can store moisture; After the installation, the lead to the hole site of adjacent air filter piece staggers mutually, changes the gas leakage area and the resistance size of breathing road thus, and then causes the hypoxia breathing environment of appropriateness.Face shield give vent to anger port bonnet air inlet port and mutually socket, protecgulum, back interior surface and air filter piece outer surface are rough rough surface.On the outer surface of pro-cover back-end and bonnet front end, the label symbol of its circumferencial direction mutual alignment of expression is arranged respectively.The protecgulum front end has some through holes to be used for ventilation.
Description of drawings: Fig. 1 is this utility model structure cutaway view
The specific embodiment:
This utility model as shown in Figure 1 is a kind of low oxygen inhalation apparatus of wet absorption carbon dioxide, and protecgulum 5 is installed a plurality of air filter pieces 6 respectively with bonnet 4 inside; Protecgulum 5 rear ends and bonnet 4 front end sleeves are connected together, and both can rotate mutually, and the label symbol of its mutual alignment of expression is arranged respectively on the outer surface; Between front cover member and the back cover part hook is arranged, the fine and closely woven projection of each air filter piece 6 both side surface uniform distribution, other has some through holes, and the through hole that the adjacent air filter piece 6 in back is installed staggers for it mutually, and face shield 3 port of giving vent to anger connects face shield 3 rear ends connection annular hollow air cushion 1 with bonnet 4 inlet end muzzles, can be 1 inflation of hollow air cushion by check valve 2, two rectangular through holes are arranged above the bonnet 4, be used for fixing the two ends of elasticity cassette tape 7, protecgulum 5 front ends have some through holes 8.The inner surface of described protecgulum 5, bonnet 4, and the outer surface of air filter piece 6 is rough rough surface.
