[0038] Furthermore, a fixed block 42 is fixedly connected to the outer wall of the motor 41, and the fixed block 42 is fixedly connected to the movable base plate 1.

By opening the arc grooves 49, the raised parts of the double-sided cams 46 can push the first guide blocks 48.

[0039] Further, the mounting assembly 6 includes a connecting rod 61, one end of the connecting rod 61 is fixedly connected to the inner wall of the connecting portion 19, the end of the connecting rod 61 away from the connecting portion 19 is fixedly connected to a U-shaped sleeve 62, the inner wall of the U-shaped sleeve 62 is provided with a second guide groove 63, the inner wall of the second guide groove 63 is symmetrically slidably connected to a second guide block 64, the second guide block 64 can slide horizontally along the inner wall of the second guide groove 63, one side of the U-shaped sleeve 62 is rotatably connected to a double-headed screw 65, the double-headed screw 65 passes through the second guide groove 63 and is threadedly rotatably connected to the second guide block 64 Then, by rotating the double-headed screw 65, the double-headed screw 65 can drive the second guide block 64 to slide horizontally, and an L-shaped synchronization rod 67 is fixedly installed on one side of the two second guide blocks 64, and a semicircular limit block 68 is fixedly installed on the end of the L-shaped synchronization rod 67 away from the second guide block 64. The second guide block 64 can move the semicircular limit block 68 through the L-shaped synchronization rod 67, and the inner wall of the semicircular limit block 68 is in active contact with the outer wall of the limit groove 132. When the two semicircular limit blocks 68 are in contact with the limit groove 132, the breathing airbag 13 can be conveniently fixed.

[0040] Furthermore, a handle 66 is fixedly mounted on one end of the double-headed screw 65 , and by rotating the handle 66 , the handle 66 can drive the double-headed screw 65 to rotate.

[0041] Working principle: When the patient needs to breathe air, the staff first connects the breathing mask 15 to the patient's face, and adds the solvent for filtering carbon dioxide into the preparation barrel 21 through the delivery pipe 23. The solvent added to the preparation barrel 21 immerses the delivery pipe 23, and then introduces external air into the preparation barrel 21 through the delivery pipe 23, and the introduced air contacts the solvent in the preparation barrel 21;

[0042] Subsequently, by turning on the motor 41, the driving shaft of the motor 41 drives the rotating rod 43 to rotate, and the rotating rod 43 causes the stirring rod 28 to rotate synchronously through the two transmission wheels 44 and the transmission belt 45. While the stirring rod 28 rotates, the multiple stirring blades 3 are rotated through the connecting sleeve 29. While the multiple stirring blades 3 rotate, the solvent in the preparation barrel 21 is stirred, so that the air and the solvent react fully. The reaction between the solvent and the air causes the carbon dioxide in the air to be decomposed. At the same time, the air after the carbon dioxide is filtered rises and enters the air storage bag 17 through the air outlet pipe 27 and the third connecting pipe 18, thereby conveniently realizing the filtration of carbon dioxide in the air, thereby effectively improving the effect of subsequent patient treatment;

[0043] At the same time, the rotating rod 43 drives the double-sided cam 46 to rotate. When the convex parts on both sides of the double-sided cam 46 are no longer in contact with the corresponding arc groove 49, the two telescopic rods 5 and the two telescopic springs 51 are rapidly extended, and the two first guide blocks 48 slide toward each other along the inner walls of the corresponding first guide groove 47. The two first guide blocks 48 move the two arc extrusion blocks 53 toward each other through the corresponding moving plates 52. The two arc extrusion blocks 53 move toward each other and squeeze the breathing airbag 13 at the same time. When the convex parts on both sides of the double-sided cam 46 contact the corresponding arc groove 49 again, the two first guide blocks 4 8 slides backwards, the two arc-shaped extrusion blocks 53 move backwards and stop extruding the breathing airbag 13, and with the reciprocating rotation of the bilateral cam 46, the two arc-shaped extrusion blocks 53 reciprocate to squeeze the breathing airbag 13, and the squeezed breathing airbag 13 allows the air in the air storage bag 17 to enter the breathing mask 15 through the second connecting pipe 16 and the first connecting pipe 14 for the patient to breathe, thereby conveniently realizing the automatic reciprocating squeezing of the breathing airbag 13, thereby effectively improving the convenience of squeezing the breathing airbag 13, and avoiding the traditional manual squeezing of the breathing airbag 13 and wasting a lot of manual work time;

[0044] When the breathing bag 13 needs to be replaced, the staff turns the knob handle 66, and the handle 66 rotates the double-headed screw 65. While the double-headed screw 65 rotates, the two second guide blocks 64 slide backwards along the inner wall of the second guide groove 63. The two second guide blocks 64 move the two semicircular limit blocks 68 backwards through the corresponding L-shaped synchronization rod 67. When the two semicircular limit blocks 68 move backwards, they disengage from the limit groove 132, and then the breathing bag 13 is manually taken out, thereby facilitating the disassembly of the breathing bag 13, thereby effectively improving the convenience of replacing the breathing bag 13.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
