Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1:

[0027] See also Figures 1 to 6 A surgical anesthesia gas recovery device includes a controller 1, a recovery component 2 located above the controller 1 for recovering waste anesthesia gas, a support component 3 located on one side of the controller 1, a plurality of gas storage devices 4 provided on the support component 3, and a lifting component 5 located on one side of the controller 1, and further includes a temporary storage component 6 for temporarily storing the recovered waste gas generated during the replacement of the gas storage device 4;

[0028] The controller 1 is electrically connected to the compressor 202 , the gas flow meter 207 , the servo motor 306 , the telescopic member 501 and the electric valve 604 ;

[0029] The temporary storage assembly 6 includes an outer protective cover 601, which contains an airbag 602. When the exhaust gas enters the airbag 602, it expands, thereby allowing it to accommodate more exhaust gas. The bottom of the outer protective cover 601 is provided with an air nozzle 603, which is connected to the interior of the airbag 602 and is provided with an electric valve 604.

[0030] Furthermore, the temporary storage assembly 6 further includes a retaining ring 605 fixedly mounted on the air nozzle 603. A sealing gasket 606 is provided at the bottom of the retaining ring 605. The sealing gasket 606 is made of rubber and can form a sealing effect after contacting the extrusion ring 403.

[0031] The recovery component 2 includes a filter tank 201 arranged above the controller 1, a compressor 202 is provided on the top of the filter tank 201, the air outlet end of the compressor 202 is connected to the interior of the filter tank 201, an air inlet end of the compressor 202 is provided with an air suction hose 203, one end of the air suction hose 203 is provided with a mask 204, the mask 204 is used to align with the patient's nasal cavity to facilitate the recovery of waste gas, a support frame 205 is provided on the controller 1, an exhaust pipe 206 is provided on the support frame 205, one end of the exhaust pipe 206 is connected to the air outlet end of the filter tank 201, the exhaust pipe 206 is also connected to one end of the air bag 602, a gas flow meter 207 is provided on the exhaust pipe 206, and the gas flow meter 207 is used to detect the amount of air flow;

[0032] Specific implementation method: Air is inhaled into the suction hose 203 through the compressor 202, and the mask 204 generates negative pressure to recover the anesthetic waste gas breathed by the patient. The anesthetic waste gas enters the filter tank 201 and then enters the air bag 602 through the exhaust pipe 206, and then enters the bottle body 401 below through the air nozzle 603 to complete the collection. When the controller 1 detects through the gas flow meter 207 that the waste gas passing through is close to the volume value of the bottle body 401, the electric valve 604 is closed. At this time, the waste gas will enter the air bag 602, causing it to expand, achieving a temporary storage effect.

[0033] Example 2:

[0034] See also Figures 1 to 6 This embodiment provides a technical solution based on the first embodiment: the support assembly 3 includes a fixing frame 301 fixedly connected to the controller 1, a main shaft 302 is rotatably connected to the fixing frame 301, a rotating disk 303 is provided at the top of the main shaft 302, and a plurality of storage holes 304 are opened on the rotating disk 303;

[0035] The support assembly 3 further includes a driven gear 305 fixedly mounted on the main shaft 302. A servo motor 306 is disposed in the fixed frame 301. A driving gear 307 is disposed on the output shaft of the servo motor 306. The driving gear 307 is meshed with the driven gear 305.

[0036] The support assembly 3 can support multiple gas storage devices 4, and can be driven by the servo motor 306 to rotate accurately, making replacement convenient;

[0037] The gas storage device 4 includes a bottle body 401, which is placed in the storage hole 304. A valve body 402 is provided on the bottle body 401, and an extrusion ring 403 is provided on the bottle body 401. After rising, the extrusion ring 403 can resist the sealing gasket 606, which is convenient for sealing the connection position to prevent exhaust gas from overflowing. A limiting sleeve 404 is provided on the fixed sleeve of the bottle body 401, and the limiting sleeve 404 is used to support the bottle body 401.

[0038] The lifting assembly 5 includes a telescopic member 501 provided on the controller 1. The telescopic member 501 can use an electric push rod or a pneumatic cylinder. A push plate 502 is provided at the telescopic end of the telescopic member 501.

[0039] Specific implementation: When the gas storage device 4 needs to be replaced, the operator closes the valve body 402 and starts the telescopic part 501 to drive the push plate 502 to move downward. At this time, the bottle body 401 loses thrust and separates from the gas nozzle 603 under its own gravity. Then the servo motor 306 is started to drive the driven gear 305 engaged with it to rotate through the driving gear 307. At this time, the main shaft 302 can drive the rotating disk 303 to rotate a certain angle, and move the unused gas storage device 4 to the bottom of the gas nozzle 603. Then, it is pushed upward through the telescopic part 501 so that its top opening is inserted into the gas nozzle 603, and the extrusion ring 403 presses against the sealing gasket 606.
