[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figure 1 , Figure 2 , Figure 4An embodiment of this utility model provides an anesthetic gas purification device, including a purification box 11. A box door 3 is rotatably connected to the front side of the purification box 11. A connector 8 is fixedly connected to the right side of the box door 3. A threaded head insert 9 is threadedly connected to the inside of the connector 8. A positioning block 23 is fixedly connected to the inside of the right side of the purification box 11. A through groove 24 is opened inside both the positioning block 23 and the purification box 11. A trapezoidal block 26 is slidably connected to the front and rear of the inside of the positioning block 23. A telescopic rod 25 is fixedly connected to one side of the trapezoidal block 26. A spring 27 is sleeved on the outside of the telescopic rod 25. One end of the telescopic rod 25 is fixedly connected to the inside of the through groove 24. The threaded head insert 9 is slidably connected to the inside of the positioning block 23. The trapezoidal block 26 is slidably connected to the inside of the threaded head insert 9. A moving component is fixedly connected to the bottom of the purification box 11. One end of the spring 27 is fixedly connected to one side of the trapezoidal block 26. The other end of the spring 27 is fixedly connected to the inner wall of the through groove 24. The threaded head insert 9 is threadedly connected to the inside of the purification box 11.
[0032] The movable component includes a base 1, which is fixedly connected to the bottom of the purification box 11. All-wheel casters 2 are fixedly connected to the four corners of the bottom of the base 1. A handle 4 is fixedly connected to the upper left side of the purification box 11.
[0033] By rotating the threaded rod 9, it moves inside the positioning block 23 and simultaneously inside the purification box 11. As the threaded rod 9 moves, it presses against the trapezoidal block 26. This pressing of the trapezoidal block 26 then presses against the telescopic rod 25 and the spring 27, causing the trapezoidal block 26 to separate from the threaded rod 9 and move into the through slot 24. This allows the box door 3 to be pulled open, opening the doors in front of the three filter boxes and allowing for easy replacement of the filter components. This facilitates simple and convenient disassembly and replacement of the filter components, preventing long-term failure to effectively purify anesthetic gases. Pushing the handle 4 causes the device to rotate via the base 1 and the casters 2, thus moving the device.
[0034] Reference Figure 1 , Figure 2 , Figure 3A filter box 12 is fixedly connected to the upper side of the interior of the purification box 11. A filter screen 17 is slidably connected from top to bottom inside the filter box 12. A filter element 18 is provided at the bottom of the filter screen 17. An activated carbon adsorption layer 19 is provided at the bottom of the filter element 18. A first connecting pipe 13 is fixedly connected to the bottom right side of the filter box 12. A filter box 24 is fixedly connected to one end of the first connecting pipe 13. A filter plate 22 is slidably connected inside the filter box 24. A second connecting pipe 15 is fixedly connected to the outer left side of the filter box 24. A filter box 3 16 is fixedly connected to one end of the second connecting pipe 15. Two HEPA filters 20 are slidably connected inside the filter box 3 16. An exhaust pipe 10 is fixedly connected to the inner left side of the filter box 3 16.
[0035] A suction pump 6 is fixedly connected to the upper right side of the base 1. A suction pipe 7 is fixedly connected to the input end of the suction pump 6. An air supply pipe 5 is fixedly connected to the output end of the suction pipe 7. One end of the air supply pipe 5 is fixedly connected to the top of the filter box 12.
[0036] By activating the suction pump 6, the suction tube 7 draws in the anesthetic gas exhaled by the patient. The anesthetic gas then travels through the gas delivery tube 5 to the interior of filter box 12, where it is filtered by the internal filter screen 17, filter element 18, and activated carbon adsorption layer 19. It then travels through the first connecting pipe 13 to the interior of filter box 24, where it undergoes secondary filtration by the filter plate 22. Finally, it enters filter box 3 16 through the second connecting pipe 15, where it undergoes a third filtration by the HEPA filter 20. Finally, it is discharged from the device through the exhaust pipe 10. This process effectively filters solid particles and harmful substances from the anesthetic gas exhaled by the patient, preventing environmental pollution in the operating room and harm to medical personnel.
[0037] Working principle: When the device is needed, the suction pump 6 is activated, driving the suction tube 7 to draw in the anesthetic gas exhaled by the patient. The gas is then delivered through the gas delivery tube 5 to the interior of filter box one 12, where it is filtered by the filter screen 17, filter element 18, and activated carbon adsorption layer 19. It then passes through the first connecting pipe 13 to the interior of filter box two 14, where it undergoes secondary filtration by the filter plate 22. Finally, it enters the interior of filter box three 16 through the second connecting pipe 15, where it undergoes a third filtration by the HEPA filter 20. This multi-stage filtration of the anesthetic gas exhaled by the patient avoids... This design avoids environmental pollution in the operating room and harm to medical staff. By rotating the threaded rod 9, it moves out of the positioning block 23 and the purification box 11. While moving, it squeezes the trapezoidal block 26, which in turn squeezes the telescopic rod 25 and the spring 27, causing the trapezoidal block 26 to move out of the threaded rod 9. This allows the box door 3 to be pulled open, and the doors in front of the three filter boxes to be opened, enabling the replacement of the filter components inside. This allows for simple and convenient disassembly and replacement of the filter components, preventing the inability to effectively purify anesthetic gases after long-term use.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
