The motor drives the disc cam 108 to rotate, the track groove 10802 of the disc cam 108 pushes the roller 117 to reciprocate in the sliding groove 10701 of the sliding frame 107, and then the driven rod 118 drives the hollow piston 119 to reciprocate in the piston cylinder 109, and because the piston cylinder 109 and the hollow piston 119 are both provided with one-way valves with consistent air flow movement directions, when the hollow piston 119 moves towards a direction far away from the piston cylinder 109, the air in the air collection tank 112 is pumped into a space surrounded by the hollow piston 119 and the piston cylinder 109; when the hollow piston 119 moves towards the direction close to the piston cylinder 109, gas between the hollow piston 119 and the piston cylinder enters the hollow piston 119 through the vent hole 130, the gas passes through the activated carbon bag 125 and then passes through the third pipe joint 123, and part of harmful components in the gas are adsorbed in the activated carbon bag 125, so that the first-stage purification of the gas is realized; then, the gas is discharged from the bellows into the gas collecting pipe 204, discharged from the bottom of the gas collecting pipe 204, and then floated from the liquid organic solvent in the reaction tank 201 in the form of bubbles, and during the floating process, the harmful components in the gas are dissolved in the liquid organic solvent, so that the second-stage purification of the gas is realized, and finally, the gas is pumped into the gas storage tank 209 by the vacuum pump 212.
Through the regulation of motor speed, can control the flow of gaseous extraction in the unit interval, and then realize the regulation of negative pressure in the air inlet subassembly 103, when the negative pressure in the air inlet subassembly 103 is low excessively, then too big with the pressure differential of external atmospheric pressure, this pressure differential, can act on pressure regulating mouth 134, make two cycloid shells 13402 warp, prop open lip seam 13404 on the pressure regulating lip 13403, and then make the external air current gush into air inlet subassembly 103, realize the compensation of pressure, avoid the negative pressure to hang down and cause harm to patient excessively.
If the gas leaked from the mask of the patient needs to be collected or the gas generated in the laparoscopic surgery or the high-frequency electrotome surgery needs to be collected, the flexible tube 205 is communicated with the bent tube 20701 of the elastic adsorption gun 207 and the first valve 104, the first valve 104 is opened, and other gas can enter the device through the first valve 104 while the device absorbs the anesthetic waste gas.
Since the bending tube 20701 and the bending plate 20702 of the elastic adsorption gun 207 are made of carbon steel as the holder for lazy people, they can be manually bent into a desired shape to be held on the wrist or the head.
When the activated carbon bag 125 needs to be replaced, a finger of one hand is pinched on the finger groove 120, a finger of the other hand is pinched on the anti-slip teeth 122, then the locking nut 121 is screwed to be separated from the hollow piston 119, then the third pipe joint 123 is taken down, the activated carbon bag 125 is taken out, a new activated carbon bag 125 is placed, then the third pipe joint 123 is put back, and the locking nut 121 is screwed in; the locking nut 121 and the thread pair matching with each other on the hollow piston 119 have self-locking property.
The finger groove 120 facilitates the application of force by a finger on the one hand, and the protrusion of the finger groove 120 on the inner wall of the hollow piston 119 can grip the activated carbon cartridge 125 on the other hand.
The liquid organic solvent is introduced into the reaction tank 201 through any one of the gas headers 204, and is discharged through the fifth pipe connector 203.
The gas tank 209 may be replaced periodically, and the gas in the gas tank 209 may be directly discharged to the outside.
The present invention is not limited to the above-described embodiments, and those skilled in the art will be able to make various modifications without creative efforts from the above-described conception and fall within the scope of the present invention.
