[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides: an anesthetic waste gas collection bag device, including a filter box 1, an exhaust pipe 2 fixedly connected inside the filter box 1, a support block 3 fixedly connected to the outer wall of the exhaust pipe 2, a collection pipe 4 disposed inside the support block 3, the outer wall of the collection pipe 4 fitting against the inner wall of the exhaust pipe 2, a collection bag body 5 fixedly connected to the outer wall of the collection pipe 4, a threaded post 6 threadedly connected inside the support block 3, a rotating block 7 fixedly connected to the outer wall of the threaded post 6, a sliding plate 8 rotatably connected to the end of the threaded post 6 away from the rotating block 7, the outer wall of the sliding plate 8 slidingly connected to the inner wall of the support block 3, a connecting post 10 fixedly connected to the outer wall of the sliding plate 8, a retaining ring 11 fixedly connected to the outer wall of the connecting post 10, the inner wall of the retaining ring 11 abutting against the outer wall of the collection pipe 4, a first spring 9 fixedly connected to the outer wall of the sliding plate 8, the outer wall of the first spring 9 fixedly connected to the inside of the support block 3, and a moving component disposed on the lower surface of the filter box 1;

[0025] Specifically, the filter box 1 fixes the exhaust pipe 2, facilitating the discharge of filtered waste gas. The exhaust pipe 2 fixes the support block 3, which in turn supports the collection pipe 4. The collection pipe 4 facilitates the introduction of waste gas into the collection bag body 5. The outer wall of the collection pipe 4 fits against the inner wall of the exhaust pipe 2, forming a seal during the discharge process to prevent leakage. The support block 3 supports the threaded post 6, which fixes the rotating block 7. Rotating the rotating block 7 allows the threaded post 6 to slide inside the support block 3. The threaded post 6 also supports the sliding plate 8. When the threaded post 6 slides, the sliding plate 8 slides, and the sliding plate 8 will adhere to... The sliding of the inner wall of the support block 3 limits the sliding of the threaded column 6, preventing deviation during the sliding process. The first spring 9 is placed between the slide plate 8 and the support block 3. The first spring 9 will be squeezed by the sliding of the slide plate 8. The buffering effect of the first spring 9 can avoid damage caused by instantaneous contact with the collection tube 4. The slide plate 8 plays a role in fixing the connecting column 10, and the connecting column 10 plays a role in fixing the retaining ring 11, thereby allowing the retaining ring 11 to slide synchronously. The retaining ring 11 is designed to be fully engaged with the collection tube 4. The collection tube 4 can be fixed by the clamping of the retaining rings 11 on the upper and lower sides. Conversely, when the retaining ring 11 is no longer in contact with the collection tube 4, the collection bag body 5 can be removed and replaced.

[0026] Reference Figure 1 The moving component includes a base plate 12, the upper surface of which is fixedly connected to the lower surface of the filter box 1, and a caster wheel 13 is provided on the lower surface of the base plate 12. A suction pipe 14 is fixedly connected to the outer wall of the filter box 1.

[0027] Specifically, the base plate 12 supports and fixes the filter box 1. The lower surface of the base plate 12 is provided with casters 13, which facilitates moving the entire device to a suitable position and fixing it. The suction pipe 14 facilitates the introduction of exhaust gas into the interior of the filter box 1.

[0028] Reference Figure 4 and Figure 5The filter box 1 has a top cover 15 on its upper surface, and a sealing ring 16 on its outer wall. The outer wall of the sealing ring 16 fits against the inner wall of the filter box 1. A push column 17 is slidably connected inside the filter box 1. A push plate 18 is fixedly connected to the outer wall of the push column 17. The outer wall of the push plate 18 is slidably connected inside the filter box 1. A second spring 25 is fixedly connected to the outer wall of the push plate 18. The outer wall of the second spring 25 is fixedly connected inside the filter box 1. A fixed seat 19 is fixedly connected to the outer wall of the push plate 18. A first rotating shaft 20 is rotatably connected inside the fixed seat 19. A rotating plate 21 is fixedly connected to the outer wall of the first rotating shaft 20. A second rotating shaft 22 is fixedly connected to the inner wall of the rotating plate 21. A connecting seat 23 is rotatably connected to the outer wall of the second rotating shaft 22. A locking rod 24 is fixedly connected to the outer wall of the connecting seat 23. The outer wall of the locking rod 24 is slidably connected inside the filter box 1 and abuts against the inner wall of the top cover 15.

[0029] Specifically, the top cover 15 seals the interior of the filter box 1, preventing exhaust gas leakage that could cause pollution and harm. A sealing ring 16 is located on the outer wall of the top cover 15, allowing it to fit tightly against the inner wall of the filter box 1, thus forming a seal. The filter box 1 supports the push column 17, which in turn fixes the push plate 18. Pushing the push column 17 allows the push plate 18 to slide inside the filter box 1. A second spring 25 is positioned between the push plate 18 and the filter box 1. The second spring 25 is compressed by the sliding of the push plate 18, and it rebounds. When no longer compressed, it rebounds and pushes the push plate 18 to slide in the opposite direction. 18 serves to fix the fixed seat 19, which in turn supports the first rotating shaft 20, allowing the fixed seat 19 and the first rotating shaft 20 to slide synchronously. The rotating plate 21 also serves to fix the first rotating shaft 20 and can be pushed to rotate inside the filter box 1. The rotating plate 21 also supports the second rotating shaft 22, which connects the rotating plate 21 and the connecting seat 23, thereby allowing the connecting seat 23 to slide. The connecting seat 23 fixes the locking rod 24, thereby driving the locking rod 24 to slide synchronously. By sliding the locking rod 24 into or out of the top cover 15, the top cover 15 can be fixed or disassembled, facilitating the replacement of the filtrate or the cleaning of the filter box 1.

[0030] Working principle: When the device is needed, the inhalation tube 14 is connected to the exhaust outlet of the anesthesia machine. The exhaust gas will enter the interior of the filter box 1 through the inhalation tube 14. The filter box 1 is filled with filter liquid. When the exhaust gas passes through the filter liquid, the harmful components in it are adsorbed or chemically reacted by the active components in the filter liquid and thus removed. The purified exhaust gas will be discharged through the exhaust pipe 2 and enter the collection tube 4 and the collection bag body 5 for collection. When the collection bag body 5 needs to be replaced, the rotating block 7 drives the threaded column 6 to slide inside the support block 3. When the threaded column 6 slides, it will drive the sliding plate 8 to slide inside the support block 3. During the sliding process, the sliding plate 8 will drive the retaining ring 11 to slide through the connecting column 10. Thus, the collection tube 4 is released from the retaining ring 11 by the sliding of the retaining rings 11 on both sides. At this time, the collection tube 4 and the collection bag body 5 can be pulled out for replacement, which can facilitate quick replacement of the collection bag body 5, prevent the accumulation of anesthesia exhaust gas and bacterial growth, and improve work efficiency.

[0031] When the filter liquid inside the filter box 1 needs to be replaced or the filter box 1 needs to be cleaned, the push column 17 is pushed to drive the push plate 18 to slide. During the sliding process, the push plate 18 will squeeze the second spring 25. When the push plate 18 slides, it will push the fixed seat 19 and the first rotating shaft 20 to slide at the same time. During the sliding process, the first rotating shaft 20 will drive the rotating plate 21 to rotate. During the rotation of the rotating plate 21, it will pull the connecting seat 23 and the locking rod 24 to slide through the second rotating shaft 22. When the locking rod 24 slides out of the inner wall of the top cover 15, the top cover 15 and the sealing ring 16 can be removed from the inside of the filter box 1, so as to effectively adsorb and neutralize the harmful components in the exhaust gas, and at the same time facilitate the cleaning and replacement of the filter liquid, thereby improving the exhaust gas treatment efficiency. This device can not only facilitate the quick replacement of the collection bag body 5 to prevent the accumulation of anesthetic exhaust gas and the growth of bacteria, thus improving work efficiency, but also effectively adsorb and neutralize the harmful components in the exhaust gas, and at the same time facilitate the cleaning and replacement of the filter liquid, thereby improving the exhaust gas treatment efficiency.

[0032] 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.
