As an improvement, a branch pipe is arranged on the air pipe and between the regulating valve and the protection valve, and a barometer is connected to the branch pipe. The air pressure in the trachea can be visually checked through the barometer, and the damage to the bronchus caused by overlarge air pressure is avoided.
As a further improvement, the protection valve comprises a valve body, and an air inlet passage and an air outlet passage are formed on the valve body; the valve core can move up and down and is used for blocking or communicating the air inlet passage and the air outlet passage; the valve rod is used for driving the valve core to move, the lower end of the valve rod is connected with the valve core, and the upper end of the valve rod is provided with a piston; the piston is positioned in the cylinder and can move up and down along the cylinder; a support plate is fixedly arranged in the cylinder below the piston, and a spring is arranged between the support plate and the piston; the air cylinder is characterized by further comprising a communicating pipe, wherein one end of the communicating pipe is connected with the air outlet passage, and the other end of the communicating pipe is communicated with the top end of the air cylinder. The protective valve is used for setting the upper limit of air pressure in the air pipe, and the protective valve can be automatically closed once the air pressure exceeds the pretightening force of the spring, so that medical accidents are avoided. The principle is as follows: the pressure P1 of the air source is changed into P2 after the valve core is throttled. P2 enters the cylinder through the muffler and acts on the piston, the generated acting force is balanced with the acting force of the spring, and the relative position of the valve core is determined for controlling the size of P2. When P2 is increased, the force of P2 on the piston is increased, and when the force exceeds the pre-tightening force of the spring, the valve core is moved towards the closing direction until the force of the piston is balanced with the pre-tightening force of the spring. Therefore, the air pressure after the pressure stabilizing protection device can be ensured not to exceed a certain preset value. The preset value is determined by the pretightening force of the spring, the larger the pretightening force is, P2 is, and conversely, the smaller the pretightening force is, P2 is, the smaller the pretightening force is.

Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the specific embodiments.
As shown in fig. 1, fig. 2 and fig. 3, the present invention includes an air source 4, the air source 4 is set according to actual conditions, and may be pure oxygen or a mixed gas of pure oxygen and air. The gas tube 6 is also included, one end of the gas tube 6 is connected with the gas source 4, and the other end is connected with the inspection mask 1; the air pipe 6 is provided with an adjusting valve 3 for adjusting the size of air flow and a protection valve 2 for limiting the upper limit of air pressure; and a branch pipe is arranged between the regulating valve 3 and the protective valve 2 on the air pipe 6, and a barometer 5 is connected to the branch pipe. The inspection mask 1 comprises a mask body 11, and an inspection hole for the bronchoscope to pass through is formed in the mask body 11. Specifically, the mask comprises a T-shaped three-way pipe 12, wherein an opening at one end of the three-way pipe 12 is communicated with the mask body 11, an opening at the opposite end is an opening of an inspection hole, and an opening at the other end is connected with the air pipe 6. The connection between the examination mask 1 and the air tube 6 is preferably by means of bellows 14. A protective cover 13 for closing the inspection opening is also included. An elastic diaphragm 15 is arranged in the inspection hole, and the diaphragm 15 is a plurality of petals which can be spliced into a circular shape. The membrane 15 is preferably 3 flaps.
The protection valve 2 comprises a valve body 21, wherein an air inlet passage 24 and an air outlet passage 25 are formed on the valve body 21; the valve core 23 can move up and down to block or communicate the air inlet passage 24 and the air outlet passage 25; the valve rod 22 is used for driving the valve core 23 to move, the valve rod 22 is vertically arranged, the lower end of the valve rod 22 is connected with the valve core 23, and the upper end of the valve rod is provided with a piston 26; the piston 26 is positioned in the cylinder and can move up and down along the cylinder; a support plate 27 is fixedly arranged below the piston 26 in the cylinder, and a spring 28 is arranged between the support plate 27 and the piston 26; it is foreseen that the support plate 27 is provided with a through hole for the passage of the valve stem. And the air cylinder further comprises a communicating pipe 30, wherein one end of the communicating pipe 30 is connected with the air outlet passage 25, and the other end of the communicating pipe is communicated with the top end of the air cylinder.

When the mask is used, the face of the infant to be inspected is covered with the inspection mask, and the mouth and the nose are shielded, so that the opening of the inspection hole is opposite to the mouth of the infant. The air source is used for providing continuous positive pressure oxygen (or mixed gas of oxygen and air) for the infant to assist the infant in breathing. The regulating valve is used for regulating the air pressure, and the protective valve is used for ensuring the highest upper limit of the air pressure in the pipeline. The constant oxygen forms PEEP for the checked infant, PEFP is also called end-expiratory positive pressure, which can increase functional residual capacity, make the alveolus not easy to trap at the end of expiration, increase the end-expiratory lung capacity, improve the alveolar-arterial blood oxygen partial pressure difference, promote the regression of pulmonary interstitium and pulmonary alveolar edema, thereby improving the alveolar diffusion function and ventilation/blood flow ratio, reducing intra-pulmonary circulation and achieving the purpose of improving oxygenation and lung compliance.
The following is a comparison of the oxygen saturation of an infant undergoing bronchoscopy with and without the use of the respiratory apparatus.
Wherein oxygen saturation in 50 groups of the data using the breathing apparatus is (97.06 + -1.89)%.
