[0041] In an example embodiment of this specification, an anesthetic absorption test device is provided. The anesthetic absorption test device can be used in scenarios for testing the adsorption effect of anesthetic adsorption materials that absorb anesthetic agents in anesthetic waste gas, and can specifically be used for filling and fixing different types of anesthetic adsorption materials. For example, the anesthetic adsorption materials can be different types of activated carbon.

[0042] According to the anesthetic absorption test device provided in the embodiments of this specification, the structure is simpler, the manufacturing cost is lower, and when the test is completed or the anesthetic adsorption material is replaced, it is convenient to clean the anesthetic absorption test device, reducing the cleaning difficulty of the anesthetic absorption test device. At the same time, it can avoid the influence on the test results due to incomplete cleaning, ensuring the accuracy of the test results. In addition, it can ensure that the anesthetic adsorption material can be fully filled into the accommodation tank body, so that the anesthetic adsorption material on at least the intake end side can fully adsorb the gas to be tested, and the quick-release connection outlet end cover is convenient for replacing the anesthetic adsorption material from the outlet end side. The operation is simple, the process is simple, and the test efficiency of anesthetic adsorption is effectively improved.

[0043] Reference Figures 1 to 3 As shown, the anesthetic absorption test device 01 may include an accommodation tank body 1, an intake end cover 2, and an outlet end cover 3. Among them:

[0044] Both ends of the accommodation tank body 1 are through and in a hollow cylindrical shape. Its cross-section can be circular or square, and this embodiment is not limited thereto. The accommodation tank body 1 can be used to fill and accommodate the anesthetic adsorption material. In this way, when the anesthetic adsorption material is filled into the accommodation tank body 1, it is convenient to fill, and when the anesthetic adsorption material is replaced, it is also convenient to pour out the anesthetic adsorption material and clean. The accommodation tank body 1 may include an intake connection end 11 and an outlet connection end 12. The intake connection end 11 is provided at one end of the accommodation tank body 1, and the outlet connection end 12 is provided at the other end of the accommodation tank body 1. In this way, the anesthetic waste gas containing anesthetic agent entering from one end can be fully absorbed by the anesthetic adsorption material, improving the test effect.

[0045] The intake end cover 2 can be connected to the intake connection end 11 for airtight sealing of the intake connection end 11. The intake end cover 2 may include an intake pipe 21, and the intake pipe 21 can be used to dock with the gas pipeline for transmitting the gas to be tested containing anesthetic waste gas. In order to enable the anesthetic waste gas containing anesthetic agent to effectively and fully contact with the anesthetic adsorption material filled in the accommodation tank body 1, the inner diameter of the accommodation tank body 1 is generally larger, while the inner diameter of the gas pipeline for transmitting the gas to be tested containing anesthetic waste gas is generally smaller. By providing the intake pipe 21 on the intake end cover 2, the connection between the external gas pipeline and the anesthetic absorption test device 01 can be effectively realized, so that the anesthetic absorption test device 01 can adapt to many scenarios. It can be understood that the intake pipe 21 can be detachably connected to the intake end cover 2. For example, threads can be provided on the outer side wall of the intake pipe 21, and screw holes can be provided at the connection of the intake end cover 2. The intake pipe 21 can be tightly connected to the intake end cover 2 through the threads and screw holes. In this way, intake pipes 21 with different inner diameters can be preset to adapt to test gas transmission pipelines with different inner diameters, further expanding the application range of the anesthetic absorption test device 01.

[0046] The air outlet end cover 3 can be connected to the air outlet connection end 12 for hermetically closing the air outlet connection end 12. The air outlet end cover 3 can include an air outlet pipe 31, and the air outlet pipe 31 can be used to dock with a gas pipeline for transmitting the gas to be tested adsorbed by the anesthetic adsorption material. By providing the air outlet pipe 31 on the air outlet end cover 3, the connection between the external gas pipeline and the anesthetic absorption test device 01 can be effectively realized, so that the anesthetic absorption test device 01 can adapt to many scenarios. It can be understood that, similar to the intake pipe 21, the air outlet connection end 12 can be detachably connected to the air outlet end cover 3, or air outlet pipes 31 with different inner diameters can be preset to improve the application range of the anesthetic absorption test device 01.

[0047] The intake end cover 2 can be tightly connected to the intake connection end 11, and the air outlet end cover 3 is connected to the air outlet connection end 12 in a quick-release manner. In this way, when filling the anesthetic adsorption material into the anesthetic absorption test device 01, the intake end cover 2 can be tightly connected to the intake connection end 11 first, and then the anesthetic adsorption material can be filled. To ensure the test effect, the anesthetic adsorption material needs to be pressed. By tightly connecting the intake end cover 2 to the intake connection end 11, the stability of the end cover during the filling of the anesthetic adsorption material can be effectively ensured. At the same time, after the filling is completed, the air outlet connection end 12 can be hermetically closed through the quick-release connection between the air outlet end cover 3 and the air outlet connection end 12, effectively simplifying the operation of installing the air outlet end cover 3. And when replacing the anesthetic adsorption material, the air outlet end cover 3 can be quickly opened to complete the replacement of the anesthetic adsorption material in the accommodation tank body 1, shortening the replacement cycle and effectively improving the test efficiency of anesthetic absorption.

[0048] In an exemplary embodiment of this specification, referring to Figures 1 to 8 as shown, the intake end cover 2 can include a first connection cover plate 22, a first filter barrier layer 23, and a first pressing plate 24. Among them:

[0049] The first connection cover plate 22 can be a plate with a shape the same as the cross-sectional shape of the accommodation tank body 1. For example, if the cross-sectional shape of the accommodation tank body 1 is circular, then the first connection cover plate 22 can be a circular plate; if the cross-sectional shape of the accommodation tank body 1 is square, then the first connection cover plate 22 can be a square plate. This exemplary embodiment does not make special limitations on this. Subsequently, it will be described by taking the cross-sectional shape of the accommodation tank body 1 as circular and the first connection cover plate 22 as a circular plate as an example.

[0050] The intake pipe 21 can be arranged on one side of the first connection cover plate 22, and the intake connection end 11 can be fixedly connected to the outer edge of the first connection cover plate 22. Optionally, screw holes can be provided on the intake connection end 11, connection holes can be provided on the outer edge of the first connection cover plate 22, and the first connection cover plate 22 and the intake connection end 11 can be fixedly connected by using fasteners through the screw holes and the connection holes. Of course, other fixed connection methods can also be adopted between the intake connection end 11 and the first connection cover plate 22, and the present exemplary embodiment is not limited thereto.

[0051] The first filter barrier layer 23 can be arranged on the side of the first connection cover plate 22 away from the intake pipe 21, and is used for filtering the gas to be tested transmitted from the intake pipe 21 and the intake through hole 222 into the interior of the accommodation tank body 1, and preventing the anesthetic adsorption material inside the accommodation tank body 1 from leaking out through the intake pipe 21. For example, the first filter barrier layer 23 can be a primary filter cotton or a sound-absorbing cotton. The present exemplary embodiment does not make special limitations on the constituent material of the first filter barrier layer 23. The diameter of the first filter barrier layer 23 can be smaller than that of the first connection cover plate 22, but the diameter of the first filter barrier layer 23 is larger than the inner diameter of the intake pipe 21, so that the first filter barrier layer 23 can fully cover the intake pipe 21.

[0052] The first pressing plate 24 can be arranged on the side of the first filter barrier layer 23 away from the first connection cover plate 22 and is fixedly connected to the first connection cover plate 22, and is used for fixing the first filter barrier layer 23 on the first connection cover plate 22. Optionally, the first pressing plate 24 can include at least one through hole. For example, the first pressing plate 24 can be provided with one through hole, and the diameter of this through hole can be greater than or equal to the inner diameter of the intake pipe 21. Of course, the first pressing plate 24 can be provided with multiple through holes, as long as it is ensured that the gas to be tested passing through the first filter barrier layer 23 by the intake pipe 21 can pass through the first pressing plate 24 without hindrance. The present exemplary embodiment does not make special limitations on the setting method of the first pressing plate 24.

[0053] The first filter barrier layer 23 can be fixed on the first connection cover plate 22 through the first pressing plate 24, so as to fully filter the gas to be tested input by the intake pipe 21, avoid the influence of interfering impurities, improve the accuracy of the anesthetic adsorption test, and at the same time, through the first filter barrier layer 23, it can also be ensured that while the gas to be tested is filtered, the anesthetic adsorption material in the accommodation tank body 1 will not leak out through the intake pipe 21.

[0054] Optionally, referring to Figures 5 to 7 as shown, the first connection cover plate 22 can include a first cover plate body 221, an intake through hole 222 and a connection flange 223. Among them:

[0055] The intake through-hole 222 can be provided through the first cover body 221, and the intake pipe 21 can be arranged on one side of the first cover body 221 and communicated with the intake through-hole 222.

[0056] The connecting flange 223 can be arranged on the side of the first cover body 221 away from the intake pipe 21 and fixedly connected to the first cover body 221. For example, the connecting flange 223 can be integrally formed and connected with the first cover body 221, or can be fixedly connected through a snap structure. This exemplary embodiment does not make special limitations on this. Optionally, the projection of the intake through-hole 222 on the extension surface of the first cover body 221 is inside the projection of the connecting flange 223.

[0057] Among them, the first filter barrier layer 23 can be arranged in the recess formed by the first cover body 221 and the connecting flange 223 and cover the intake through-hole 222. In this way, it can be ensured that the gas to be tested input from the intake pipe 21 can be fully filtered by the first filter barrier layer 23. The first pressing plate 24 can be fixedly connected through fasteners based on the connecting holes distributed on the outer edge and the connecting holes on the connecting flange, so as to press the first filter barrier layer 23 in the recess formed by the first cover body 221 and the connecting flange 223, so that there is no gap between the first filter barrier layer 23 and the intake through-hole 222, ensuring the full filtration of the gas to be tested input from the intake pipe 21.

[0058] Optionally, the connecting flange 223 can include a limiting groove 2231. The limiting groove 2231 can be arranged on the outer peripheral side of the connecting flange 223, and the outer diameter of the connecting flange 223 can be equal to or slightly smaller than the inner diameter of the accommodating tank body 1. In this way, when the intake end cover 2 is fixedly connected to the intake connection end 11 of the accommodating tank body 1, the connecting flange 223 is inside the accommodating tank body 1, and the outer peripheral surface of the connecting flange 223 is in contact with the inner side wall of the accommodating tank body 1 at the intake connection end 11 to complete the sealing, which can effectively improve the airtightness of the intake end cover 2 to the intake connection end 11.

[0059] At this time, the anesthetic absorption test device 01 can further include a sealing gasket 4. The sealing gasket 4 can be arranged in the limiting groove 2231 and can be used to make part of the sealing gasket 4 abut against the inner side wall of the intake connection end 11 when the intake end cover is connected to the intake connection end, realizing the airtight sealing of the accommodating tank body 1 and further improving the airtightness of the intake end cover 2 to the intake connection end 11.

[0060] It can be understood that, as shown in Figure 2 and Figure 4 The intake connection end 11 can further form a stepped surface on the inner side wall of the accommodating tank body 1, and the connecting flange 223 on the first connecting cover 22 can be in contact connection with the stepped surface on the intake connection end 11, further improving the airtightness of the intake connection end 11.

[0061] In an exemplary embodiment of the present specification, with reference to Figures 1 to 8 as shown, the air outlet end cover 3 may include a second connecting cover plate 32, a second filtering and blocking layer 33, and a second pressing plate 34. Among them:

[0062] The second connecting cover plate 32 may be a plate having the same cross-sectional shape as that of the accommodating tank body 1. For example, if the cross-sectional shape of the accommodating tank body 1 is circular, then the second connecting cover plate 32 may be a circular plate; if the cross-sectional shape of the accommodating tank body 1 is square, then the second connecting cover plate 32 may be a square plate. This exemplary embodiment does not make any special limitation thereto. Subsequently, the case where the cross-sectional shape of the accommodating tank body 1 is circular and the second connecting cover plate 32 is a circular plate will be taken as an example for description.

[0063] The air outlet pipe 31 may be provided on one side of the second connecting cover plate 32. The air outlet connecting end 12 and the second connecting cover plate 32 may be connected by a connecting member 35. For example, the connecting member may be a buckle, a mother-and-son buckle, or a magnetic attraction buckle. This exemplary embodiment does not make any special limitation to the form of the connecting member.

[0064] The second filtering and blocking layer 33 may be provided on the side of the second connecting cover plate 32 away from the air outlet pipe 31, for filtering the to-be-tested gas that has been subjected to adsorption treatment inside the accommodating tank body 1, and preventing the anesthetic adsorption material inside the accommodating tank body 1 from leaking out through the air outlet pipe 31. The diameter of the second filtering and blocking layer 33 may be smaller than that of the second connecting cover plate 32, but the diameter of the second filtering and blocking layer 33 is larger than the inner diameter of the air outlet pipe 31, so that the second filtering and blocking layer 33 can fully cover the air outlet pipe 31.

[0065] The second pressing plate 34 may be provided on the side of the second filtering and blocking layer 33 away from the second connecting cover plate 32 and fixedly connected to the second connecting cover plate 32, and may be used to fix the second filtering and blocking layer 33 on the second connecting cover plate 32. Optionally, the second pressing plate 34 may include at least one through hole. For example, the second pressing plate 34 may be provided with one through hole, and the diameter of the through hole may be greater than or equal to the inner diameter of the air outlet pipe 31. Of course, the second pressing plate 34 may be provided with a plurality of through holes, as long as it is ensured that the to-be-tested gas passing through the second filtering and blocking layer 33 by the air outlet pipe 31 can pass through the second pressing plate 34 unobstructed. This exemplary embodiment does not make any special limitation to the setting manner of the first pressing plate 24.

[0066] The second filter barrier layer 33 can be fixed to the second connection cover plate 32 through the second pressing plate 34, so as to fully filter the gas to be tested input by the air outlet pipe 31, avoid the influence of interfering impurities, improve the accuracy of the anesthetic adsorption test, and at the same time, through the second filter barrier layer 33, it can also ensure that while the gas to be tested is filtered, the anesthetic adsorption material in the accommodating tank body 1 will not leak out through the air inlet pipe 21.

[0067] Optionally, the second connection cover plate 32 may include a second cover plate body 321, an air outlet through hole 322, a surrounding flange 323, and a connection edge 324. Among them:

[0068] The air outlet through hole 322 may be provided through the second cover plate body 321, and the air outlet pipe 31 may be provided on one side of the second cover plate body 321 and communicate with the air outlet through hole 322.

[0069] The surrounding flange 323 may be provided on the side of the second cover plate body 321 away from the air outlet pipe 31 and fixedly connected to the second cover plate body 321. For example, the surrounding flange 323 may be integrally formed and connected with the second cover plate body 321, or may be fixedly connected through a snap structure.
