The air blow bag is a compression cylindrical air blow bag which is provided with elasticity and can be compressed, the air chamber control valve comprises a valve body, a piston, a movable sliding rod, and a spring part, the valve body is a three-way cylindrical valve body, and front end cover and a back end cover with a plurality of holes are respectively arranged at the both ends of the valve body, and a piston rod is arranged on the central axles of the front end cover and the back end cover, a piston sliding on the piston rod is sleeved on the piston rod, and a spring is connected between the back end cover and the piston, the hole on the side wall of the valve body is connected with the air intake tube, and a face mask is arranged on the air intake tube. The utility model has the advantages of simple structure, small volume, easy carryover and convinient operation.

Description

The portable first-aid respiratory organ

Technical field

This utility model relates to cease breathing patient's apparatus of a kind of rescue, belongs to medicine and hygiene fields.

Background technology

At present; the methods of the gas of the generally many employing nostril interpolation pipe oxygen supplys of salvage at scene respiratory arrest patient clinically; in the outdoor method that is still life-kiss; though being field conducts, these methods rescue the critical patient; the important method that the patient is recovered as early as possible; but often cause cross infection; though it is effective to utilize respirator to rescue at large hospital; but because complex structure; volume is big, and the scene is connected and installed bothersome, requires the operating technology height; the field of employment is restricted, and is not easy to outdoor portably using.

Summary of the invention

The purpose of this utility model is exactly at using existing apparatus to rescue the problem that the respiratory arrest person exists, provide a kind of simple in structure, volume is little, portably uses breathing apparatus tool easily.

The purpose of this utility model is to realize like this, this breathing apparatus comprises the air blowing capsule, the air chamber control valve, the air inlet pipe part, described air blowing capsule is to have the cylindrical shape that elasticity can be compressed, described air chamber control valve comprises valve body, piston, movable sliding bar, spring section, described valve body is the cylindrical shape of a threeway, its two ends are respectively equipped with the drive end bearing bracket with a plurality of holes, rear end cap, pro-, the central axis of rear end cap is provided with a piston rod, upper cover of piston rod a piston that can slide thereon, rear end cap is connecting a spring with piston space, hole and air inlet pipe on the described body wall are joined, and air inlet pipe is provided with a face shield.

Owing to adopt said structure, air inlet pipe is inserted in patient's mouth, face shield seals face, at this moment, compression air blowing capsule, air in the air blowing capsule enters in the air chamber control valve by the hole of drive end bearing bracket, promoting piston compression spring moves backward, when piston is drawn back when exposing the gas outlet of air inlet pipe on the sidewall, this moment, a large amount of fresh airs entered in patient's mouth by air inlet pipe, when stopping to blow, entered the expiration state, piston travels forward under the elastic force of spring, when piston moved to rear end face and exposes gas outlet on the sidewall, the waste gas that the patient breathes out was discharged through the hole of rear end cap, moves in circles like this, reach the purpose that helps patient respiratory, have simple in structure, advantage easy to use.
