In summary, the one-way valve mechanism 9 allows external air to enter the connection box 8 only through the air inlet pipe 2, and the air inside the connection box 8 can only be discharged through the exhaust pipe 3. The driving motor 1101 is driven by the pulley 1105 and the belt 1106 to rotate the threaded rod 1104. Since the limit rod 1102 limits the pressing plate 1103 to follow the rotation of the threaded rod 1104, the pressing plate 1103 moves left and right, thereby reciprocatingly compressing the airbag 10, so that the air can be continuously delivered into the airbag. When the device is out of power inside the patient's body, rotate the compression cover 5 and remove it from the right end of the shell 1. Then, put your hand through the handle and hold the compression cover 5. By pressing the compression cover 5 back and forth, the compression cover 5 presses the air bag 10 back and forth, and manual pumping can be performed. It can be used for temporary emergency use when there is no power. Add pure water to the liquid box 402, and then guide the pure water to the atomizing sheet 401 through the absorbent cotton strip. The pure water is atomized by the atomizing sheet 401, and the atomized water vapor remains in the connection box. 8, humidify the air inside the connection box 8, rotate the knob 706 to align the notch 707 with the slide groove 705, and the filter box 702 can be directly ejected by the elastic member 704, and the filter sponge 701 can be replaced. After replacing the filter sponge 701, insert the filter box 702 into the air intake pipe 2 and loosen the knob 706. The torsion spring will reset the knob 706, and the slide groove 705 can be blocked by the knob 706 to prevent the filter box 702 from falling.

The right end of the shell 1 is threadedly connected to the compression cover 5. The left side of the cover 5 is rotated and connected to the right side of the right airbag 10. The one-way valve mechanism 9 allows external gas to enter the connecting box 8 only through the air inlet pipe 2, and the gas inside the connecting box 8 can only be discharged through the exhaust pipe 3. The driving motor 1101 is driven by the pulley 1105 and the belt 1106 to rotate the threaded rod 1104. Since the limit rod 1102 limits the pressing plate 1103 to rotate with the threaded rod 1104, the pressing plate 1103 moves horizontally left and right, thereby reciprocatingly compressing the airbag 10, so that air can be continuously delivered into the patient's body. When the device is out of power, rotate the compression cover 5 and remove the compression cover 5 from the right end of the shell 1. Then, pass your hand through the handle and hold the compression cover 5.

After replacing the filter sponge 701, the filter box 702 is inserted into the intake pipe 2 and the knob 706 is loosened. The torsion spring will reset the knob 706, and the slide groove 705 can be blocked by the knob 706 to prevent the filter box 702 from falling. Installation and disassembly are very simple and convenient.

[0028] The humidifying mechanism 4 includes an atomizing sheet 401, a liquid box 402 and a water-absorbing cotton strip. The atomizing sheet 401 is installed at the lower part of the connecting box 8, the water-absorbing cotton strip is installed at the lower part of the atomizing sheet 401, the water-absorbing cotton strip is arranged inside the liquid box 402, and the upper part of the liquid box 402 is threadedly connected to the lower part of the shell 1. Pure water is added to the liquid box 402, and then the pure water is guided to the atomizing sheet 401 through the water-absorbing cotton strip. The pure water is atomized by the atomizing sheet 401, and the atomized water vapor remains inside the connecting box 8 to humidify the air inside the connecting box 8.

[0029] The one-way valve mechanism 9 includes a sealing ring 901, a fixing frame 902, a connecting rod 903, a limiting block 904, a sealing block 905 and a spring 906. The fixing frame 902 is installed inside the exhaust pipe 3. The outer periphery of the connecting rod 903 is slidably connected to the inside of the fixing frame 902. The middle of the limiting block 904 is fixedly connected to one end of the connecting rod 903. The middle of the sealing block 905 is fixedly connected to the other end of the connecting rod 903. The sealing ring 901 is installed inside the exhaust pipe 3 near the side of the sealing block 905. The spring 906 is sleeved on the outer periphery of the connecting rod 903. The connecting rod 9 03 is arranged between the fixing frame 902 and the sealing block 905, and the spring 906 pushes the sealing block 905 so that the sealing block 905 blocks the middle part of the sealing ring 901, thereby making the one-way valve mechanism 9 in a normally closed state. When the airbag 10 is opened, the air pressure inside the airbag 10 and the connecting box 8 is low, so that the outside air opens the one-way valve mechanism 9 inside the intake pipe 2 and enters the inside of the connecting box 8. When the airbag 10 is closed, the air pressure inside the airbag 10 and the connecting box 8 increases, thereby making the one-way valve mechanism 9 inside the exhaust pipe 3 open, so that the air is discharged.

[0030] Working principle:

[0031] Through the one-way valve mechanism 9, external gas can only enter the connection box 8 through the air inlet pipe 2, and the gas inside the connection box 8 can only be discharged through the exhaust pipe 3, driving the motor 1101, and through the transmission of the pulley 1105 and the belt 1106, the threaded rod 1104 rotates. Since the limit rod 1102 limits the pressing plate 1103 to follow the rotation of the threaded rod 1104, the pressing plate 1103 moves left and right, thereby reciprocatingly compressing the airbag 10, so that air can be continuously delivered into the patient's body. When the device is out of power, rotate the compression cover 5 and remove the compression cover 5 from the right end of the shell 1. Then, put your hand through the handle and hold the compression cover 5. By pressing the compression cover 5 back and forth, the compression cover 5 reciprocates to press the airbag 10, and manual pumping can be performed. For temporary emergency use in the absence of electricity, add pure water to the liquid box 402, and then guide the pure water to the atomizing sheet 401 through the absorbent cotton strip, and atomize the pure water through the atomizing sheet 401. The atomized water vapor remains in the connection box 8 to humidify the air inside the connection box 8. Rotate the knob 706 to align the notch 707 with the slide 705, and the filter box 702 can be directly popped out through the elastic member 704, and the filter sponge 701 can be replaced. After replacing the filter sponge 701, insert the filter box 702 into the air intake pipe 2 and loosen the knob 706. The torsion spring will reset the knob 706, and the slide 705 can be blocked by the knob 706 to prevent the filter box 702 from falling. Installation and disassembly are very simple and convenient.
