[0002] Anesthetic waste gas refers to the volatile gas generated during medical anesthesia, mainly including inhaled anesthetics such as sevoflurane, isoflurane, etc., and the volatile components of some auxiliary drugs. Long-term exposure to anesthetic waste gas environment will cause symptoms such as headache, dizziness, nausea, memory loss, etc. in medical staff, and may also have adverse effects on the reproductive system, immune system, etc. In order to protect the health of medical staff and patients, it is necessary to use an anesthetic waste gas adsorption treatment device to reduce the concentration of anesthetic waste gas in the indoor air.

[0003] When the traditional anesthetic waste gas adsorption treatment device treats waste gas, it needs to manually replace the activated carbon and stop the machine for operation, and it is necessary to open the device, take out the old activated carbon and load the new activated carbon. The process is relatively cumbersome, time-consuming, and affects the timeliness of anesthetic waste gas treatment. During the period of stopping the machine to replace the activated carbon, anesthetic waste gas may accumulate locally, causing safety problems, such as discomfort or even poisoning of personnel due to too high anesthetic waste gas concentration.

The fan extracts the anesthetic waste gas in the collection cylinder through the first delivery pipe and the first delivery pipe and sends it into the detection cylinder. When the anesthetic waste gas passes through the separation box, the water, sevoflurane, isoflurane, etc. in the anesthetic waste gas are absorbed by the activated carbon; S3: Turn on the gas monitor and monitor the anesthetic waste gas in the detection cylinder.

At this time, the second motor is started to drive the rotating seat to rotate 90 degrees, so that a new separation box adsorbs and treats the waste gas. Then the electronic valve is opened to continue detecting the anesthetic waste gas; S4: When the separation box with saturated adsorbed activated carbon rotates 90 degrees, the top block is pushed into the space between the two arc-shaped limiting plates, and the separation box falls into the discharge pipe and is removed by the first hydraulic cylinder; S5: Place the separation box with the replaced activated carbon on the top plate. Rotate the rotating base again, start the first motor, drive the lifting plate to rise through the screw rod, and push the separation box with the replaced activated carbon into the vacant air vent.

[0016] Compared with the related technologies, the anesthesia waste gas adsorption treatment device and treatment method provided by the present invention have the following beneficial effects: The present invention provides an anesthesia waste gas adsorption treatment device. Through the cooperation of a grooved wheel, a dial, a second motor, a rotating base, a first delivery pipe, a blower, and a gas monitor, the continuity of waste gas treatment can be ensured. When the activated carbon in one separation box is saturated, the rotating base can immediately rotate the separation box filled with fresh activated carbon to the working position, so that the adsorption treatment of anesthesia waste gas will not be interrupted, effectively ensuring the continuous purification of indoor air. There is no need to stop the machine to replace the activated carbon as in the traditional method. The device can operate continuously, greatly improving the treatment efficiency of anesthesia waste gas, reducing the frequency of manual replacement of activated carbon, and lowering the labor cost and labor intensity. Through the cooperation of a partition board, a top block, a fourth spring, a first spring, an arc-shaped limiting plate, a discharge pipe, a reset plate, a transfer plate, a first hydraulic cylinder, a placement pipe, a lifting plate, a screw rod, and a first motor, the whole process does not require manual direct participation in the disassembly and installation of the central cylinder. It can automatically complete the removal of the saturated central cylinder, and only requires manual placement of a new central cylinder, greatly improving the work efficiency, reducing the chance of manual contact with anesthesia waste gas and activated carbon, and reducing the safety hazards such as the health risks brought by long-term contact with anesthesia waste gas by operators and the dust hazards generated when handling activated carbon. The present invention provides an anesthesia waste gas adsorption treatment device. Through the cooperation of a second roller, a sixth spring, a movable magnet, a seventh spring, a second filter box, a guide bar, a first roller, a fifth spring, a guide rod, a push plate, a connecting rod, a cam, a third motor, a belt, and a rotating disc, the discharge and filling of activated carbon in the central cylinder can be automatically completed without manual handling, which can significantly improve the work efficiency, and can ensure that the activated carbon is evenly and tightly filled in the central cylinder, ensuring the stability and consistency of the adsorption effect. Moreover, the whole process can avoid long-term manual contact with anesthesia waste gas and activated carbon dust, reducing the harm to the surrounding environment and personnel, and avoiding safety problems such as poisoning and allergy caused by long-term contact with activated carbon or anesthesia waste gas during the manual operation process, thus protecting the physical health of the operators. The present invention provides an anesthetic waste gas adsorption and treatment device. Through the cooperation of a fifth motor, a feed hopper, a feed pipe, a screw conveyor, a conductive sheet, and a conical disk, it ensures that the same amount of activated carbon is loaded each time, so that the adsorption capacity of each separation box remains consistent, thereby ensuring the stable treatment effect of the entire anesthetic waste gas adsorption and treatment device. The adsorption effect will not be uneven due to differences in the loading amount of activated carbon. Moreover, it precisely controls the loading amount of activated carbon, avoiding waste caused by overloading and insufficient adsorption capacity caused by underloading, making more reasonable use of activated carbon resources and reducing the operating cost. Through the cooperation of a limiting pipe, a lifting cylinder, a third spring, a conical disk, and a second hydraulic cylinder, when the second hydraulic cylinder drives the lifting cylinder to descend, through the contact between the conical disk and the activated carbon, it can accurately sense the loading height of the activated carbon and stop loading when the set amount is reached, ensuring that the loading height is consistent each time and further improving the loading accuracy.

[0017] The present invention provides an anesthetic waste gas adsorption and treatment method. By using the above-mentioned anesthetic waste gas adsorption and treatment device to treat anesthetic waste gas, it greatly facilitates the replacement work of activated carbon and is conducive to improving the work efficiency of relevant operators.

The gas monitor 8 is turned on, and the gas monitor 8 starts to monitor the waste gas after adsorption treatment in the detection cylinder 6. When the waste gas in the detection cylinder 6 still contains sevoflurane and isoflurane, the electronic valves on the first delivery pipe 20 and the second delivery pipe 22 are closed, the second motor 24 is started, and the dial 37 is driven to rotate through the output shaft. When the dial 37 rotates, the grooved wheel 38 is driven to rotate through the cooperation of the dial rod and the linkage groove. At this time, the rotating seat 14 rotates by ninety degrees, and the separation box 26 filled with saturated activated carbon is moved directly above the discharge pipe 3. At this time, the top block 33 extends into the arc-shaped groove and pushes the two arc-shaped limiting plates 19 apart, so that the two arc-shaped limiting plates 19 move away from each other, and the separation box 26 falls to the bottom of the discharge pipe 3.

A transfer plate 17 is arranged in the second opening. A first hydraulic cylinder 2 is fixedly installed on the outer wall of the discharge pipe 3. A telescopic end of the first hydraulic cylinder 2 is fixedly connected to the transfer plate 17. The lifting and inserting device includes a screw rod 10 rotatably installed on the top of the base 1. A first motor 9 is fixedly installed on an outer wall of the insertion pipe 12.

A top plate is fixedly installed on the top of the lifting plate 18. The discharge pipe 3 and the insertion pipe 12 are both communicated with corresponding communication ports.

[0024] Four annular grooves are provided on the top of the rotating base 14. First isolation blocks 28 are arranged in the four annular grooves. One end of a second spring 27 is fixedly installed at the bottom of the first isolation block 28. The other end of the second spring 27 is fixedly connected to the annular groove. A second isolation block 29 is fixedly installed at the bottom of the fixed disk 30. Annular inclined surfaces are provided at one ends of the second isolation block 29 and the first isolation block 28 close to each other. The two annular inclined surfaces are in fit. When the rotating base 14 rotates by ninety degrees, a new separation box 26 will rotate to directly below the fixed disk 30, and the second isolation block 29 and the first isolation block 28 will contact to prevent waste gas leakage.

[0025] The working principle of the anesthesia waste gas adsorption and treatment device provided by the present invention is as follows: First, inject anesthetic waste gas into the collection cylinder 4 through the injection pipe 11. Then, convey water to the spray pipe 23 through the water injection pipe. The water sprayed by the spray pipe 23 reduces the solid dust particles in the waste gas. Subsequently, start the fan 13. The fan 13 pumps the waste gas in the collection cylinder 4 into the detection cylinder 6 through the first conveying pipe 20 and the second conveying pipe 22. When the waste gas passes through the separation box 26, the activated carbon in the separation box 26 absorbs the moisture, sevoflurane, isoflurane, etc. in the waste gas. Open the gas monitor 8, and the gas monitor 8 starts to monitor the waste gas after adsorption treatment in the detection cylinder 6. When the waste gas in the detection cylinder 6 still contains sevoflurane and isoflurane, the electronic valves on the first conveying pipe 20 and the second conveying pipe 22 close, and the second motor 24 starts and drives the dial 37 to rotate through the output shaft. When the dial 37 rotates, it drives the sheave 38 to rotate through the cooperation of the dial rod and the linkage groove. At this time, the rotating seat 14 rotates 90 degrees, moving the separation box 26 filled with saturated activated carbon to directly above the discharge pipe 3. At this time, the top block 33 extends into the arc-shaped groove and pushes the two arc-shaped limit plates 19 apart, causing the two arc-shaped limit plates 19 to move away from each other. The separation box 26 falls to the bottom of the discharge pipe 3. When falling, there is a return spring at the bottom of the reset plate 16 on the discharge pipe 3, which slows down the falling speed of the separation box 26 and reduces the direct collision between the cylinder body and the pipeline. Subsequently, start the first hydraulic cylinder 2 to move the separation box 26 out. When the rotating seat 14 rotates 90 degrees, a new separation box 26 will rotate to directly below the fixed disk 30. The second isolation block 29 contacts the first isolation block 28 to prevent waste gas leakage. Open the two electronic valves and start the fan 13 to continue adsorbing and treating the waste gas. At this time, the air circulation port on the rotating seat 14 at the top of the discharge pipe 3 is vacant. When the vacant position rotates to the top of the insertion pipe 12, place the separation box 26 filled with brand-new activated carbon on the top plate of the lifting plate 18. Start the first motor 9, and the output shaft of the first motor 9 drives the screw rod 10 to rotate. The screw rod 10 drives the lifting plate 18 to rise, pushing the separation box 26 filled with brand-new activated carbon into the vacant position. Then, the two arc-shaped limit plates 19 clamp it. Subsequently, the waste gas after adsorption treatment is discharged through the discharge pipe 7, thus completing the removal of the saturated separation box 26 and the work of placing a new separation box 26.

[0026] Compared with the related technology, the anesthetic waste gas adsorption and treatment device provided by the present invention has the following beneficial effects: The present invention provides an anesthetic waste gas adsorption and treatment device. Through the cooperation of a Geneva wheel 38, a dial 37, a second motor 24, a rotating base 14, a first delivery pipe 20, a blower 13 and a gas monitor 8, it can ensure the continuity of waste gas treatment. When the activated carbon in one separation box 26 is saturated, the rotating base 14 can immediately rotate the separation box 26 filled with fresh activated carbon to the working position, so that the adsorption and treatment of anesthetic waste gas will not be interrupted, effectively ensuring the continuous purification of indoor air. There is no need to stop the machine to replace the activated carbon in the traditional way. The device can run continuously, greatly improving the treatment efficiency of anesthetic waste gas, reducing the frequency of manual replacement of activated carbon, and lowering the labor cost and labor intensity. Through the cooperation of a partition plate 15, a top block 33, a fourth spring 36, a first spring 25, an arc-shaped limiting plate 19, a discharge pipe 3, a reset plate 16, a transfer plate 17, a first hydraulic cylinder 2, a placement pipe 12, a lifting plate 18, a screw rod 10 and a first motor 9, the whole process does not require manual direct participation in the disassembly and installation of the central cylinder. It can automatically complete the removal of the saturated central cylinder, and only requires manual placement of a new central cylinder, greatly improving the work efficiency, reducing the chance of manual contact with anesthetic waste gas and activated carbon, and lowering the health risks brought to the operators by long-term contact with anesthetic waste gas, as well as potential safety hazards such as dust hazards generated during the treatment of activated carbon.

One end of a guiding rod 47 is fixedly installed at the bottom of the connecting rod 40, and the other end of the guiding rod 47 extends outside the fixed ring plate 41 and is fixedly connected with the push plate 46. A fifth spring 48 is sleeved outside the guiding rod 47, and both ends of the fifth spring 48 are fixedly connected with the connecting rod 40 and the fixed ring plate 41 respectively.

A discharge port is provided on one side of the charging and discharging cylinder 65 away from the third motor 42, and a centralized box 21 is provided on the top of the base 1. When the third motor 42 is started, the output shaft of the third motor 42 drives the rotating disc 45 to rotate by 90 degrees through the belt 44. During the rotation, through the cooperation of the cam 39 and the first roller 49, the push plate 46 starts to push the separation box 26 and separates the separation box 26 from the second filter frame 35.

[0030] Pulley wheels are fixedly installed on the output shaft of the third motor 42 and the outer wall of the rotating rod, and the same belt 44 is sleeved outside the two pulley wheels.

[0031] When the first hydraulic cylinder 2 drives the transfer plate 17 through its telescopic end to push the separation box 26 onto the rotating disk 45, the electromagnet 66 on the rotating disk 45 is powered on. At this time, the electromagnet sucks out the movable magnet 50 at the bottom of the second filter frame 35 and fixes the second filter frame 35 on the rotating disk 45. Then, the third motor 42 is started. The output shaft of the third motor 42 drives the rotating disk 45 to rotate by ninety degrees through the belt 44. During the rotation, through the cooperation of the cam 39 and the first roller 49, the push plate 46 starts to push the separation box 26 and separates the separation box 26 from the second filter frame 35. At this time, the activated carbon in the separation box 26 is poured out and concentrated in the concentration box 21. Subsequently, the rotating disk 45 is rotated by ninety degrees again. At this time, the push plate 46 no longer pushes the separation box 26 and returns to its original position. The separation box 26 slides to the top of the second filter frame 35. The first filter frame 31 is opened to load new activated carbon into the separation box 26. After the loading is completed, there is a return spring on the first filter frame 31, which automatically rotates back to its original position. The electromagnet 66 is powered off, and the fourth motor 43 is started. The output shaft of the fourth motor 43 drives the cam 39 to rotate, and the separation box 26 is pushed into the insertion tube 12 again through the push plate 46. Through the setting of the above components, the present invention can automatically complete the discharge of the activated carbon in the concentration cylinder without manual handling, which can significantly improve the work efficiency, and can ensure that the activated carbon is evenly and tightly filled in the concentration cylinder, ensuring the stability and consistency of the adsorption effect. Moreover, the whole process can avoid the long-term contact of artificial with anesthetic waste gas and activated carbon dust, reduce the harm to the surrounding environment and personnel, and avoid safety problems such as poisoning and allergy caused by long-term contact with activated carbon or anesthetic waste gas during the manual operation process, thus protecting the physical health of the operators.

[0032] Third Embodiment: Based on the anesthetic waste gas adsorption and treatment device provided in the second embodiment of the present application, a third embodiment of the present application proposes another anesthetic waste gas adsorption and treatment device. The third embodiment is only a preferred way of the second embodiment, and the implementation of the third embodiment will not affect the independent implementation of the second embodiment.

[0033] The following further describes the third embodiment of the present invention in conjunction with the drawings and embodiments.

[0034] Please refer to Figures 18 - 23, the anesthetic waste gas adsorption and treatment device further includes a fixed cylinder 57, which is fixedly installed at the top of the charging and discharging cylinder 65. An inlet pipe 58 is fixedly installed on the outer wall of the fixed cylinder 57. A screw conveyor 62 is rotatably installed in the inlet pipe 58. One end of the inlet pipe 58 away from the fixed cylinder 57 is fixedly installed with a fifth motor 55. The output shaft of the fifth motor 55 extends into the inlet pipe 58 and is fixedly connected to one end of the screw conveyor 62. A feed hopper 56 is also fixedly installed on the outer wall of the inlet pipe 58. A lifting cylinder 63 is arranged in the fixed cylinder 57. A guiding connecting plate is fixedly installed on the outer wall of the lifting cylinder 63. One end of the guiding connecting plate extends outside the fixed cylinder 57. A second hydraulic cylinder 59 is fixedly installed on the outer wall of the fixed cylinder 57. The telescopic end of the second hydraulic cylinder 59 is fixedly connected to the guiding connecting plate. A limiting pipe 60 is arranged on the outer wall of the lifting cylinder 63. An annular fixed plate and an annular flow guiding plate are fixedly installed on the inner wall of the lifting cylinder 63. Three connecting arms 64 are slidably installed on the annular fixed plate. The bottoms of the three connecting arms 64 are fixedly installed with the same conical plate 61. The tops of the three connecting arms 64 are all fixedly installed with limiting pieces. Conductive sheets 32 are fixedly installed on the tops of the limiting pieces and the bottoms of the annular flow guiding plates. The second hydraulic cylinder 59 drives the lifting cylinder 63 to descend through the telescopic end. The limiting pipe 60 pushes open the first filter frame 31. The conical plate 61 extends into the separation box 26. When the amount of activated carbon in the separation box 26 continuously rises and contacts the conical plate 61, it drives the conical plate 61 to rise, so that the two conductive sheets 32 are in contact. At this time, the fifth motor 55 no longer drives the screw conveyor 62 to rotate and no longer fills the activated carbon. Thus, it can ensure that the same amount of activated carbon is filled each time, so that the adsorption capacity of each separation box 26 remains consistent, ensuring the stable treatment effect of the entire anesthetic waste gas adsorption and treatment device, and preventing the adsorption effect from being uneven due to differences in the filling amount of activated carbon. Moreover, the filling amount of activated carbon is precisely controlled, avoiding waste caused by overfilling and insufficient adsorption capacity caused by underfilling.

[0035] The three connecting arms 64 are rotationally symmetrically distributed on the annular fixed plate at an angle of 120 degrees.

[0036] A third spring 34 is sleeved on each of the three connecting arms 64 above the annular fixed plate. The tops of the three third springs 34 are fixedly connected to the corresponding limiting pieces. The bottoms of the three third springs 34 are fixedly connected to the top of the annular fixed plate.

[0037] The fifth motor 55 is started, and the output shaft of the fifth motor 55 drives the auger 62 to rotate, and the activated carbon is poured into the feed hopper 56. The auger 62 drives the activated carbon to be transported to the fixed cylinder 57. At this time, the second hydraulic cylinder 59 is started, and the second hydraulic cylinder 59 drives the lifting cylinder 63 to descend through the telescopic end, and the limiting tube 60 opens the first filter frame 31, and the conical disk 61 extends into the separation box 26. When the amount of activated carbon in the separation box 26 continues to increase, it contacts the conical disk 61 and drives the conical disk 61 to rise, so that the two conductive sheets 32 contact. At this time, the fifth motor 55 no longer drives the auger 62 to rotate, and no longer loads activated carbon. The second hydraulic cylinder 59 drives the lifting cylinder 63 to rise through the telescopic end, so that the limiting tube 60 and the conical disk 61 are away from the separation box 26, thus completing the Regarding the filling of activated carbon, the present invention can ensure that the same amount of activated carbon is filled each time through the arrangement of the above-mentioned components, so that the adsorption capacity of each separation box 26 remains consistent, thereby ensuring the stability of the treatment effect of the entire anesthetic waste gas adsorption treatment device, and will not cause uneven adsorption effects due to differences in the activated carbon filling amount. The activated carbon filling amount can be accurately controlled to avoid waste caused by overfilling and insufficient adsorption capacity caused by underfilling, so that activated carbon resources can be more reasonably utilized and operating costs can be reduced. When the second hydraulic cylinder 59 drives the lifting cylinder 63 to descend, the contact between the conical disk 61 and the activated carbon can accurately sense the filling height of the activated carbon, and stop filling when the set amount is reached, ensuring the height of each filling amount is consistent, further improving the filling accuracy.
