The output end of the one-way valve 220 is communicated with an oxygen feeding pipe 230, and the other end of the oxygen feeding pipe 230 penetrates through the air return control plate 210 and is communicated with an oxygen outlet pipe 240. A plurality of groups of air return pipes 241 are distributed on the side wall of the oxygen outlet pipe 240 in an annular array. A plurality of groups of air outlets 250 are distributed on the outer wall of the air return control panel 210 in an annular array, and each group of air outlets 250 is fixedly provided with a group of guide plates 260.

Firstly, the oxygen mask 201 is covered at the mouth and the nose of a patient, then the breathing machine body 100 is started, and oxygen is transmitted to the oxygen mask 201 for the patient to use through the breathing machine body 100 by the one-way valve 220, the oxygen delivery pipe 230 and the oxygen outlet pipe 240 in sequence. The carbon dioxide exhaled by the patient will also return to the oxygen delivery tube 230 through the oxygen outlet tube 240, but due to the obstruction of the one-way valve 220, the carbon dioxide gas is discharged into the return air control plate 210 through the plurality of sets of return air tubes 241 distributed in the annular array and then discharged through the air outlet 250. So that the carbon dioxide can be discharged quickly, the carbon dioxide is prevented from being doped with the oxygen due to long-term leaving, the purity of the oxygen is ensured, and the use effect of the breathing machine body 100 is improved.

The patient's head and neck are fixed by the face fixing plate 510 and the side limiting plate 420, and the angle and position of the face fixing unit 500 can be adjusted at will by the first stretching strap 473, at this time, the first stretching strap 473 is in a loose state, so that the patient's head can move slightly, thereby improving the comfort of the patient. When the swing of the patient's head is too great due to struggling spasm, the sensing plate 454 is touched, and the servo motor 471 is operated to contract the first tension band 473 to tighten it, so that the face fixing plate 510 fixes the patient's head. The head of the oxygen therapy mask is prevented from being damaged secondarily, and the oxygen therapy mask 201 is prevented from falling off, so that the using effect of the auxiliary breathing device is improved. Second pillow 410 is scalene trapezoid, and the contained angle between first lateral wall 411 and roof 412 will be greater than the contained angle of second lateral wall 413 and roof 412, consequently, first lateral wall 411 and second lateral wall 413 all can be laminated completely at patient's neck, avoid patient's neck to appear unsettling to patient's uncomfortable sense when the first aid has been reduced. When the patient struggles spasm, especially face upwards faces upward, will make its throat cause the extrusion to facial fixed plate 510, then utilize the rotatable characteristic of release link 542, drive jack catch body 522 and rotate to make first baffle 520 break away from second baffle 530, also let two sets of facial fixed plates 510 break away from each other, and no longer cause the extrusion to patient's throat, guaranteed the smooth and easy of its respiratory track. When the face fixing plate 510 deforms due to external force, the external force is absorbed by the four groups of stretching rods 551 hinged end to end in sequence, the stretching rods act on the second spring 554 in the inner cavity 552, then the two groups of tip abutting blocks 553 bounce by the elasticity of the second spring 554, and then the diamond-shaped structure is supported by the two groups of tip abutting blocks 553, so that the reset is completed. And thus the external force is absorbed, and the injury of the external force to the head of the patient is avoided. The protective effect of the face fixing unit 500 is improved. The carbon dioxide exhaled by the patient will return to the oxygen tube 230 through the oxygen outlet tube 240, but due to the obstruction of the one-way valve 220, the carbon dioxide gas will be exhausted into the return air control plate 210 through the several sets of return air tubes 241 distributed in the annular array and then exhausted through the exhaust port 250. So that the carbon dioxide can be discharged quickly, the carbon dioxide is prevented from being doped with the oxygen due to long-term leaving, the purity of the oxygen is ensured, and the use effect of the breathing machine body 100 is improved.
