The invention has the working principle and advantages that: when the medical emergency respirator device for the hyperbaric oxygen chamber is used, the working process is as follows:

as shown in fig. 2, fig. 3 and fig. 4, when the breathing machine is actually used for a patient, the mask 20 is covered on the face of the patient, so that the mouth and nose of the patient are all located at the inner side of the mask 20, the motor 48 is started to work, the motor 48 drives the shaft lever 44 to rotate through the bevel gear set 31, and then the shaft lever 44 drives the sliding block 46 to rotate around the central axis of the shaft lever 44 through the telescopic rod 32, so that the sliding block 46 drives the connecting rod 33 to carry out reciprocating horizontal movement through the sliding frame 10, and then the connecting rod 33 synchronously drives the piston plate two 8 to carry out reciprocating movement in the pump cylinder two 13, when the piston plate two 8 moves leftwards in the pump cylinder two 13, the oxygen in the pump cylinder two 13 is pressurized, so that the oxygen in the pump cylinder two 13 is conveyed into the mask 20 through the air pipe six 16, the patient carries out inhalation action during the process, when the piston plate two 8 moves rightwards in the pump cylinder two 13, the oxygen in the air tank is sucked into the pump cylinder two 13 through the air pipe five 15, so that the patient does not carry out the oxygen circulation during the oxygen delivery, and thus the breathing mechanism is assisted by the patient.

According to different conditions of different patients, when the breathing machine is used, the screw 9 is rotated to drive the sliding plate II 25 to move in the sliding cylinder II 28 by utilizing screw transmission, so that the sliding plate II can convey hydraulic oil in the sliding cylinder II 28 into the sliding cylinder I3201 through the liquid pipe IV 29 and the liquid pipe III 45, or suck hydraulic oil in the sliding cylinder I3201 into the sliding cylinder II 28 through the liquid pipe IV 29 and the liquid pipe III 45, the sliding plate I3203 can drive the sliding rod 3202 to extend or retract in the sliding cylinder I3201, the length of the telescopic rod 32 is adjusted, the moving distance of the sliding block 46 in the direction of the connecting rod 33 is adjusted, the moving travel distance of the sliding plate II 8 in the pump cylinder II 13 is driven by the connecting rod 33, the oxygen delivery amount is adjusted in one breathing process, and the breathing machine is simple and convenient to operate and suitable for different patients.

The waste gas exhaled by the patient is conveyed into the disinfectant box 24 through the air outlet valve 39 and the air pipe III 38, and is discharged through the exhaust pipe 26 after being disinfected by the disinfectant, so that the waste gas exhaled by the patient is prevented from polluting the environment in the cabin 1.

As described above, the connecting rod 33 simultaneously drives the piston plate 7 to reciprocate horizontally in the pump cylinder one 12, as shown in fig. 2, when the piston plate 7 moves rightwards in the pump cylinder one 12, the disinfectant in the disinfectant box 24 is pumped into the liquid cavity through the liquid pipe two 22, and when the piston plate 7 moves leftwards in the pump cylinder one 12, the disinfectant in the pump cylinder one 12 is conveyed into the nozzle 23 through the liquid pipe one 11 and sprayed into the disinfectant box 24 through the nozzle 23, so that the disinfectant can circulate on one hand, and on the other hand, the disinfectant in a spraying state can disinfect the exhaust gas rising from the liquid surface again, thereby improving the disinfection effect on the exhaust gas.

When the face mask 20 is worn on the face of a patient, the silica gel patches 41 are attached to the skin of the face, rib marks and discomfort are not caused to the skin of the face of the patient because silica gel is soft, when the piston plate I7 moves leftwards in the pump barrel I12, air in the negative pressure box 49 is sucked into the air cavity through the air pipe II 37, so that the air pressure in the negative pressure box 49 is lower than the external air pressure, the negative pressure box 49 is further used for sucking out the air in the groove 43 through the air pipe IV 42, the silica gel patches 41 are tightly attached to the face of the patient by using the pressure difference, on one hand, the face mask 20 is not required to be fixed by using a bandage, the comfort level of the patient is improved, on the other hand, the air tightness between the face mask 20 and the face of the patient is kept, and the auxiliary effect of the breathing machine on the breathing system of the patient is improved.

When the piston plate I7 moves rightwards in the pump cylinder I12, air in the air cavity is discharged through the air pipe I35, the air cavity is reciprocated in this way, so that oxygen is fed to a patient and the negative pressure state in the negative pressure box 49 is kept continuously, the stable and reliable oxygen feeding process to the patient is kept, the pressure valve 40 on the negative pressure box 49 is used for opening when the air pressure in the negative pressure box 49 is too low, and external air enters the negative pressure box 49 for pressure regulation and pressure maintaining, so that the groove 43 is always in a balanced low-pressure state, namely, the stable attaching force of the silica gel patch 41 and the face of the patient is kept, and after the use is finished, the mask 20 is taken off from the face of the patient.
