The three-way switching valve 21 on the air intake pipe 14 is in two states: the air intake pipe 14 is connected to the air bag 13 and the storage chamber 26 is connected to the air bag 13 .

[0022] like Figure 5 As shown, the three-way conversion valve 21 is provided with a valve driver 1 23 for state switching, and the control valve 22 is provided with a valve driver 2 24 for state switching.

The scraper 31 is snapped onto the annular rail 37 through the locking groove 38, so that the scraper 31 is still attached to the inner wall of the airbag 13 after the rotation state, thereby completely scraping and cleaning the inner wall of the airbag 13.

[0026] like Figure 3 and Figure 5 As shown, the airbag 13 is connected to the air inlet end of the breathing joint 15 through the connecting pipe 18, and the air outlet end of the breathing joint 15 is connected to the air outlet pipe 16. Both the connecting pipe 18 and the air outlet pipe 16 are provided with a one-way valve.

When the driver 17 is driven to rotate, it will periodically pull the pressure plate 12, thereby pressing the airbag 13 downward, and the elasticity of the airbag 13 itself realizes the reset of the pressure plate 12. Figure 2 As shown, the pressing plate 12 is provided with a clearance hole for the connecting pipe 18 to pass through.

[0028] In summary, the present invention also has the following comprehensive effects: dual-mode switching mechanism, in the first state of the emergency mode, the three-way conversion valve 21 closes the passage of the storage chamber 26, the control valve 22 is opened, oxygen enters the airbag 13 through the air inlet pipe 14, and is delivered to the patient through the breathing joint 15, and the pressure plate 12 periodically compresses the airbag 13 to achieve artificial respiration.

The locking structure, the annular rail 37 cooperates with the locking groove 38 to ensure that the scraper 31 always moves along the inner wall track of the airbag 13 when rotating, covering the cleaning dead corner. Intelligent control linkage, the controller 25 synchronously switches the three-way valve and the control valve 22 to achieve seamless mode conversion; the flow sensor 110 monitors the respiratory flow in real time and feeds back to the controller 25 to adjust the compression frequency of the driver 17 to match the patient's breathing needs; Efficient self-cleaning and cross-infection prevention, the dual-mode design automatically switches to the cleaning state after first aid, the cleaning agent flushing combined with the physical scraping of the scraper 31 completely removes the pathogens / secretions in the airbag 13, significantly reducing the risk of cross infection; flexible cleaning does not interfere with the first aid function, the flexible telescopic structure of the scraper 31 ensures the normal deformation of the airbag 13 during compression / expansion, and the cleaning action is only performed after the mode is switched to avoid the mechanical resistance affecting the compression efficiency during the first aid process; accurate oxygen supply and intelligent adjustment of the closed-loop control of the flow sensor 110 and the controller 25 to achieve on-demand oxygen supply, such as automatically increasing the compression frequency according to the patient's weak breathing, and improving the success rate of first aid. Long life and low maintenance, the locking member 33 and the annular rail 37 reduce the wear of the scraper 31, and the spring buffer of the telescopic member 35 reduces mechanical fatigue, extending the service life of the airbag 13 and the cleaning component.
