[0053] Working or installation process:

[0054] Open the oxygen cylinder and put the oxygen mask on the patient's mouth and nose, oxygen enters the airbag 20, the reciprocating motor 28 is started, the output shaft of the reciprocating motor 28 drives the reciprocating gear 27 to rotate, the reciprocating gear 27 meshes with the first rack 25 and the second rack 26 and drives the first rack 25 and the second rack 26 to move, the first rack 25 and the second rack 26 move towards each other, the first rack 25 drives the first slider 16 to move toward the side close to the airbag 20, the second rack 26 drives the second slider 18 to move toward the side close to the airbag 20, the first slider 16 and the second slider 18 squeeze the airbag 20 at the same time and make the airbag 20 deform, the oxygen in the airbag 20 is squeezed into the three-way pipe 19, the three-way pipe 19 quickly transports the oxygen to the trachea of ​​the oxygen mask and transports the oxygen to the oxygen mask through the trachea to provide it for the patient to breathe;

[0055] After the first slider 16 and the second slider 18 squeeze the airbag 20, the reciprocating motor 28 is started in the reverse direction, and the output shaft of the reciprocating motor 28 drives the reciprocating gear 27 to rotate in the reverse direction, and the reciprocating gear 27 drives the first rack 25 and the second rack 26 to move, and the first rack 25 drives the first slider 16 to move to the side away from the airbag 20, and the second rack 26 drives the second slider 18 to move to the side away from the airbag 20. After the airbag 20 is no longer squeezed by the first slider 16 and the second slider 18, oxygen continues to flow into the airbag 20, and the airbag 20 expands outward and deforms to the initial state through the material of the airbag 20 and the oxygen flowing into the airbag 20.

[0056] When the airbag 20 is deformed and restored to its initial state, the reciprocating motor 28 is started forward again, and the above operation is repeated, so that the rear end bracket 15 and the second slider 18 continuously reciprocate and squeeze the airbag 20 to provide oxygen to the patient.

[0057] If the weather is relatively dry, the humidifier 13 is started, the humidifier 13 generates water vapor, and passes the water vapor into the connecting pipe 29. The connecting pipe 29 passes the water vapor into the three-way pipe 19 to mix with oxygen, thereby increasing the humidity of the air and making it more suitable for patients to inhale.

[0058] If the reciprocating motor 28 is damaged during use and oxygen cannot be provided to the patient, the medical staff pushes the push rod 24, and the push rod 24 slides in the guide tube 23 toward the side close to the airbag 20. The end of the push rod 24 close to the airbag 20 squeezes the airbag 20 and causes the airbag 20 to deform. The airbag 20 deforms and delivers oxygen to the patient, thereby avoiding sudden damage to the equipment that causes the inability to deliver oxygen to the patient in time.

[0059] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept.
