Simple respirator capable of adjusting air-blowing depth

Abstract

The invention discloses a simple respirator capable of adjusting air-blowing depth. The simple respirator comprises a respiratory mask, an airbag and an oxygen storage bag, wherein a limiting block isfixedly arranged on the outer side, close to embedding holes, of an airbag box; a push plate is movably arranged on one side, far away from a connection hole I, of the airbag box; the airbag is connected with the respiratory mask through a respiratory tube; the airbag is connected with the oxygen storage bag through an oxygen connecting tube; the limiting block comprises a fixed block and a movable clamping block; a stop block is movably connected with the fixed rod; the fixed rod is fixedly connected with a reset rod; and an embedding rod and a limiting rod are fixed to the movable clampingblock. According to the simple respirator capable of adjusting the air-blowing depth disclosed by the invention, the pressure against the airbag can be adjusted and limited according to situations ofpatients, accurate quantification is achieved, over-high or over-low pressure caused by a manual operation is avoided, and the recovery of a breathing function of a patient is not affected; moreover,an airbag strap is arranged on an oxygen mask and can be tightly adhered with faces of the different patients, so that air leakage during oxygen supply is reduced.

Description

technical field [0001] The invention relates to the technical field of simple respirators, in particular to a simple respirator with adjustable inflation depth. Background technique [0002] The simple respirator has the characteristics of convenient use, light pain, few complications, easy to carry, and can be ventilated immediately with or without an oxygen source. Provide lung ventilation for patients when performing first aid. The existing use of simple respirators mainly relies on the operation of medical personnel. Damage lung tissue, cause respiratory system disorder, and affect the recovery of respiratory function. [0003] In the prior art, a simple respirator with the application number "201720141963.2" includes an airbag, one end of the airbag is connected to a hose, and the other end of the hose is divided into two branch pipes, and each branch pipe is connected to an air acceleration The two air acceleration devices are connected with an air filter, the two ai...

[0002] The simple respirator has the characteristics of convenient use, light pain, few complications, easy to carry, and can be ventilated immediately with or without an oxygen source. Provide lung ventilation for patients when performing first aid. The existing use of simple respirators mainly relies on the operation of medical personnel. Damage lung tissue, cause respiratory system disorder, and affect the recovery of respiratory function

[0003] In the prior art, a simple respirator with the application number "201720141963.2" includes an airbag, one end of the airbag is connected to a hose, and the other end of the hose is divided into two branch pipes, and each branch pipe is connected to an air acceleration The two air acceleration devices are connected with an air filter, the two air filters are connected with the inlet end of the three-way valve, the outlet end of the three-way valve is connected with the spring tube, and the other end of the spring tube is connected with the oxygen mask , an elastic rope is connected to the outside of the oxygen mask, and an exhaust hole is arranged on the outside of the oxygen mask. This simple respirator solves the problem of incomplete purification and the need to replace the respirator when the purification capacity of activated carbon is not enough, which wastes precious time for rescuing patients.

[0004] However, there are still obvious defects in its use: 1. The pressure of pressing the airbag cannot be adjusted and limited. Different patients need to squeeze the airbag to different degrees in different situations. The existing structure mainly relies on The technology of medical staff is often difficult to achieve accurate quantification in actual operation, which will affect the recovery of the patient's respiratory function; 2. The oxygen mask is not adjustable and lacks adaptability. Different patients have different faces, and there will inevitably be leaks in the fixed mask. Affect the quality of oxygen supply
