In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0023] The embodiments of this application are described below with reference to the accompanying drawings: refer to Figures 1 to 5 The anesthesia device according to an embodiment of this application includes a first pump body 110, an anesthesia bottle 410, an anesthesia structure 310, a recovery bottle 420, and a second pump body 120. The output end of the first pump body 110 is connected to a first multi-port structure 210, which includes a first outlet and a second outlet. The anesthesia bottle 410 is used to contain anesthetic, with its inlet connected to the first outlet and its outlet connected to a second multi-port structure 220, which is connected to the second outlet. The anesthesia structure 310 is connected to the second multi-port structure 220. The recovery bottle 420 is used to contain adsorbent, with its inlet connected to the anesthesia structure 310. The second pump body 120 is connected to the recovery bottle 420. Therefore, after anesthesia is completed, the suction of the second pump body 120 promotes the flow of residual anesthetic gas within the recovery bottle 420, allowing the adsorbent to more thoroughly adsorb the residual anesthetic gas, thus improving the safety of the anesthesia experiment.

[0024] Specifically, the first multi-port structure 210 and the second multi-port structure 220 can be three-way structures, and the structures can be connected by silicone tubes, namely, between the first pump body 110 and the first multi-port structure 210, between the first multi-port structure 210 and the anesthesia bottle 410, between the first multi-port structure 210 and the second multi-port structure 220, between the anesthesia bottle 410 and the second multi-port structure 220, between the second multi-port structure 220 and the anesthesia structure 310, between the anesthesia structure 310 and the recovery bottle 420, and between the recovery bottle 420 and the second pump body 120. The second pump body 120 can be connected to the outlet of the recovery bottle, or connected in series in the pipe connecting the recovery bottle. Through the suction of the second pump body 120, the residual anesthetic gas can actively flow into the recovery bottle 420 to ensure the absorption of the residual anesthetic gas.

[0025] During anesthesia, the first pump 110 is activated to provide airflow. The first multi-pass structure 210 has a diversion function. A portion of the gas generated by the first pump 110 flows through the anesthesia bottle 410, which contains an anesthetic agent, such as isoflurane solution. This solution has significant volatility, and by flowing within the anesthesia bottle 410, the anesthetic gas generated by the evaporation of the anesthetic agent can be carried away without the need for an additional anesthetic vaporizer, which helps reduce the production cost of the anesthesia device. Thus, the mixed airflow containing the anesthetic gas flows to the second multi-pass structure 220. At the same time, another portion of the gas generated by the first pump 110 flows directly to the second multi-pass structure 220 and can mix with the anesthetic gas from the anesthesia bottle 410 at the second multi-pass structure 220. Subsequently, the mixed airflow can flow to the anesthesia structure 310 to administer anesthesia to experimental animals or patients. After anesthesia is completed, the second pump 120 is activated for suction. The suction action of the second pump 120 allows the residual anesthetic gas to flow more evenly and rapidly within the recovery bottle 420. The adsorbent in the recovery bottle 420 can more fully absorb the residual anesthetic gas, effectively preventing leakage of residual gas and improving the safety of the anesthesia experiment.

[0026] It should be noted that the anesthetic can be an inhaled anesthetic such as isoflurane, halothane, enflurane, sevoflurane, or desflurane, and the adsorbent can be an adsorbent such as activated carbon, molecular sieve, or activated alumina.

[0027] In addition, to ensure a clearer understanding of the relative positions of the various structures, Figure 2 The fact that the pipes connecting the various structures are hidden does not mean that they need to be disassembled and stored after use.

[0028] refer to Figures 1 to 5In other embodiments, the first pump body 110 can be a dual-hole air pump. The output end of the first pump body 110 is provided with a three-way pipe, two openings of which are connected to the two holes of the dual-hole air pump, and the remaining opening is connected to the first multi-way structure 210. The connection can be made using a silicone tube. The two output holes of the dual-hole air pump can jointly provide airflow. Compared to a single-hole air pump, this helps reduce the impact of fluctuations in the output of a single pump body on the overall airflow stability, resulting in a more stable airflow within the device.

[0029] During operation, the dual-port gas pump starts, and gas is simultaneously output from both outlets. The gas flows into the three-way tube through the corresponding silicone tube, and after converging in the three-way tube, it flows into the first multi-way structure 210 through the silicone tube connected to the three-way tube. Subsequently, it follows the preset diversion path for subsequent gas delivery and mixing to complete the anesthesia-related operations. After anesthesia is completed, the second pump 120 starts to aspirate the recovery bottle 420, allowing the residual anesthetic gas to enter the recovery bottle 420 and be absorbed by the adsorbent.

[0030] refer to Figures 1 to 5 In some embodiments, the anesthesia device further includes a flow meter 230, wherein at least one of the following is arranged: between the first multi-port structure 210 and the second multi-port structure 220; between the anesthesia bottle 410 and the second multi-port structure 220; and between the second multi-port structure 220 and the anesthesia structure 310: the flow meter between the first multi-port structure 210 and the second multi-port structure 220 is used to regulate the air flow rate; the flow meter between the anesthesia bottle 410 and the second multi-port structure 220 is used to regulate the anesthetic gas flow rate; and the flow meter between the second multi-port structure 220 and the anesthesia structure 310 is used to regulate the airflow flow rate after the anesthetic gas is mixed. This allows for flexible adjustment of the ratio of anesthetic gas mixed in the anesthesia device, improving the flexibility of the anesthesia device's adjustment.

[0031] Specifically, the flow meter can be single or multiple, and there are seven possible configurations: First, a flow meter is arranged between the first multi-port structure 210 and the second multi-port structure 220; second, a flow meter is arranged between the anesthesia bottle 410 and the second multi-port structure 220; third, a flow meter is arranged between the second multi-port structure 220 and the anesthesia structure 310; fourth, a flow meter is arranged between the first multi-port structure 210 and the second multi-port structure 220, and also between the anesthesia bottle 410 and the second multi-port structure 220; fifth, a flow meter is arranged between the first multi-port structure 210 and the second multi-port structure 310; sixth, a flow meter is arranged between the first multi-port structure 210 and the second multi-port structure 220; seventh, a flow meter is arranged between the first multi-port structure 210 and the second multi-port structure 220; and eighth, a flow meter is arranged between the first multi-port structure 210 and the second multi-port structure 310. A flow meter is arranged between the multi-pass structures 220, and a flow meter is arranged between the second multi-pass structure 220 and the anesthesia structure 310; a sixth type is where a flow meter is arranged between the anesthesia bottle 410 and the second multi-pass structure 220, and a flow meter is arranged between the second multi-pass structure 220 and the anesthesia structure 310; a seventh type is where a flow meter is arranged between the first multi-pass structure 210 and the second multi-pass structure 220, a flow meter is arranged between the anesthesia bottle 410 and the second multi-pass structure 220, and a flow meter is arranged between the second multi-pass structure 220 and the anesthesia structure 310, which is beneficial for achieving independent regulation of airflow at each location.

[0032] Furthermore, if there are multiple anesthesia structures 310, each anesthesia structure 310 is independently connected to the second multi-port structure 220. The number of anesthesia structures 310 can be two, three, four, five, six, seven, etc. A second multi-port structure 220 with an opening adapted to the number of anesthesia structures 310 can be selected. For example, the second multi-port structure 220 can be a combination of a three-way tube and a multi-way tube. The three-way tube is used to connect the first multi-port structure 210 and the anesthesia bottle 410. Then, the three-way tube is connected to each anesthesia structure 310 through the multi-way tube.

[0033] Accordingly, the number of flow meters can be the same as the number of anesthesia structures 310, with each flow meter arranged one-to-one between the anesthesia structure 310 and the second multi-channel structure 220, so that the anesthesia structures 310 distributed in each channel can independently adjust the flow rate.

[0034] refer to Figures 1 to 5 In some embodiments, the anesthesia device further includes a storage box 510, which has a receiving cavity 511. The storage box 510 is used to store the first pump body 110, the anesthesia bottle 410, the anesthesia structure 310, the recovery bottle 420, and the second pump body 120. The flow meter is connected to the outer peripheral wall of the storage box 510. When anesthesia is performed, it does not need to be taken out of the receiving cavity 511, which facilitates reading and flow rate adjustment.

[0035] refer to Figures 1 to 5In some embodiments, the anesthesia device has a first state and a second state. In the first state, anesthesia can be administered. In the first state, the first pump body 110, the anesthesia bottle 410, the recovery bottle 420, and the second pump body 120 are located in the receiving cavity 511, while the anesthesia structure 310 is located outside the receiving cavity 511. An airflow mixed with anesthetic gas can flow out from the anesthesia structure 310, allowing the subject to absorb the gas and become anesthetized. In the second state, the first pump body 110, the anesthesia bottle 410, the recovery bottle 420, the anesthesia structure 310, and the second pump body 120 are located inside the receiving cavity 511, allowing for the storage of each component and making the entire device more convenient to carry. When switching between the first and second states, the flow meter is fixed to the outer peripheral wall of the receiving box 510, eliminating the need to disassemble the flow meter during assembly and disassembly, thus simplifying the assembly and disassembly of the anesthesia device.

[0036] Specifically, multiple flow meters can be arranged on the same side of the storage box 510, making it more convenient to observe the flow rate along different paths and to adjust the flow rate. When anesthesia is required, the anesthesia structure 310 can be removed to conduct the anesthesia experiment, making it more convenient to use. The first pump body 110 can be an air pump, and the second pump body 120 can be a circulating pump.

[0037] It should be noted that the first state refers to the state when the anesthesia device is administering anesthesia, and the second state refers to the stored state when the anesthesia device is not administering anesthesia. The switching of the first state is achieved by the experimenter changing the position of the components. In any embodiment of this application, unless otherwise specified, the relative positions and connections in the first state should be understood.

[0038] refer to Figures 1 to 5 In some embodiments, the flow meter has multiple flow meters, including at least one of a first flow meter 231, a second flow meter 232, and a third flow meter 233; A first flow meter 231 is provided between the first multi-port structure 210 and the second multi-port structure 220, and a second flow meter 232 is provided between the anesthetic bottle 410 and the second multi-port structure 220. The range of the first flow meter 231 is larger than that of the second flow meter 232, so that the air flow adjustment range can match the actual air demand during the anesthesia process. At the same time, the small range of the second flow meter 232 can more accurately control the low flow of anesthetic gas, avoiding excessive concentration due to excessive adjustment of anesthetic gas flow or insufficient adjustment leading to excessively low concentration, thereby improving the precision of the air-to-anesthetic gas ratio adjustment.

[0039] And / or, there are multiple anesthesia structures 310, each anesthesia structure 310 is independently connected to the second multi-pass structure 220, and a third flow meter 233 is provided between the second multi-pass structure 220 and each anesthesia structure 310. At least two third flow meters 233 have different ranges. On the one hand, each third flow meter 233 can independently control the airflow of the corresponding anesthesia structure 310, avoiding the influence of flow adjustment of one anesthesia structure 310 on other pathways. On the other hand, the third flow meters 233 with different ranges can adapt to the flow requirements of different anesthesia structures 310. For example, a larger flow meter range can be used to adapt to rats, and a smaller flow meter range can be used to adapt to mice.

[0040] refer to Figures 1 to 5 In some embodiments, the storage box 510 is provided with a through hole 512, which connects to the receiving cavity 511. The flow meter includes a body 234 and a flow interface 235. The flow interface 235 passes through the through hole 512. One end of the flow interface 235 is connected to the body 234, and the other end of the flow interface 235 is connected to the receiving cavity 511, so that each flow meter can be connected within the receiving cavity 511. This is beneficial to shorten the pipeline connection path and makes the connection of the anesthesia device simpler.

[0041] Specifically, when connecting the pipes, the pipes connected to the flow meter are docked inside the receiving cavity 511. Other components inside the receiving cavity 511 (such as the tee structure, pump body interface, etc.) are directly connected to the flow interface 235 of the flow meter located inside the cavity through the pipes. There is no need to lead the pipes out of the receiving box 510 and then turn back to connect them, which shortens the connection path of the pipes and allows more pipes to be concentrated in the receiving cavity 511, making the outside of the receiving cavity 511 relatively cleaner.

[0042] refer to Figures 1 to 5 In some embodiments, the anesthesia structure 310 includes an anesthesia mask 311 and an induction box 312. The anesthesia mask 311 and the induction box 312 are independently connected to the second multi-channel structure 220. The recovery bottle 420 is connected to the anesthesia mask 311 and the induction box 312. The anesthesia mask 311 is used to fit the face of the experimental subject, and the induction box 312 is used to place the experimental subject. Thus, the anesthesia mask 311 or the induction box 312 can be used alone or simultaneously, depending on the experimental requirements, to adapt to different experimental subjects or anesthesia stages, making the anesthesia device more flexible.

[0043] Specifically, the anesthesia mask 311 and the induction chamber 312 can be connected to the two output ports of the second multi-port structure 220 through independent pipes. The anesthesia mask 311 is a flexible mask that fits the face of the test subject, and the edges can be provided with silicone sealing gaskets to reduce gas leakage. The induction chamber 312 is a transparent and sealed box with an openable operating door on the side. The test subject can enter the induction chamber 312 and inhale the mixed anesthetic gas inside the induction chamber 312.

[0044] During anesthesia, the anesthetic gas, mixed through the second multi-port structure 220, can be delivered separately to the anesthesia mask 311 and the induction chamber 312 via independent pipelines. When anesthetizing small laboratory animals, the animal can be placed in the induction chamber 312, the operating door closed, and the anesthetic gas enters the chamber for initial anesthesia induction. When continuous anesthesia is required for induced animals or large experimental subjects, the anesthesia mask 311 can be used to deliver the anesthetic gas by fitting it against the animal's mouth and nose. Residual gases generated during anesthesia flow out from the exhaust ports of the anesthesia mask 311 and the induction chamber 312, and then enter the recovery bottle 420 via a shared pipeline, where they are adsorbed and treated by the adsorbent inside the recovery bottle 420. The recovery bottle 420 is connected to the exhaust ports of both, enabling centralized treatment of residual gases generated during anesthesia, preventing the anesthetic gas from spreading into the environment, helping to reduce potential hazards to operators, and improving the safety of the experimental environment.

[0045] refer to Figures 1 to 5 In some embodiments, the anesthesia device also includes a backflow prevention structure, which is arranged between the first multi-port structure 210 and the anesthesia bottle 410. The backflow prevention structure can be a check valve, which effectively prevents the anesthetic liquid in the anesthesia bottle 410 from flowing back, so as to avoid contamination or blockage caused by the anesthetic liquid entering the first multi-port structure 210, thereby protecting the normal function of the first multi-port structure 210 and upstream components and helping to extend the service life of the device.

[0046] Specifically, the check valve structure can be a spring-loaded check valve, which includes a valve body, a valve core, and a spring. One end of the spring is fixed to the outlet side inside the valve body, and the other end is connected to the valve core. The valve core can move axially inside the valve body. The first outlet of the first multi-port structure 210 is connected to the inlet of the check valve through a pipe. The outlet of the check valve is connected to the inlet of the anesthetic bottle 410 through a pipe. When gas flows from the first multi-port structure 210 to the anesthetic bottle 410, the gas pressure acts on the valve core of the check valve, overcoming the spring force and pushing the valve core to move towards the outlet side, thus opening the internal passage of the check valve. The gas can then smoothly pass through the check valve and enter the anesthetic bottle 410. When the anesthetic liquid in the anesthetic bottle 410 has a tendency to flow back due to pressure fluctuations, the liquid pressure acts on the side of the valve core facing the inlet. At the same time, the spring force pushes the valve core to move towards the inlet side, so that the valve core tightly fits the sealing surface inside the valve body, closing the internal passage of the check valve, thereby preventing the anesthetic liquid from flowing back to the first multi-port structure 210. Therefore, the anti-reverse structure not only prevents liquid backflow but also reduces the waste of anesthetics caused by liquid leakage, which is beneficial to improving the efficiency of anesthetic use.

[0047] refer to Figures 1 to 5In some embodiments, the anesthesia device further includes a first interceptor, which is disposed between the first multi-pass structure 210 and the anesthesia bottle 410. The first interceptor can be a structure with both sealing and opening functions, such as a water-stop clamp, which can seal or connect the path from the first multi-pass structure 210 to the anesthesia bottle 410. This allows the gas flow to be stopped in time when the anesthetic gas concentration is too high, preventing further increase in the anesthetic gas concentration and helping to maintain the stability of the anesthetic state.

[0048] Specifically, when there is no need to block the airflow, the stop clamp is in the open state. The gas output from the first multi-port structure 210 can flow through the silicone tube, through the stop clamp, into the anesthesia bottle 410, and continue to participate in the subsequent anesthesia process after carrying the anesthetic gas. When the proportion of anesthetic gas is too high, the operator can manually close the stop clamp to block the airflow to the anesthesia bottle 410. At this time, the gas output from the first multi-port structure 210 will no longer enter the anesthesia bottle 410, which helps to reduce the continuous input of anesthetic gas and thus adjust the concentration of anesthetic in the mixed gas. After the anesthesia experiment is completed, the stop clamp can also be closed to block the airflow to the anesthesia bottle 410. At this time, the gas output from the first multi-port structure 210 can flow as a cleaning airflow in the device. With the suction action of the second air pump, the residual anesthetic gas in the device is carried into the recovery bottle 420 and absorbed by the adsorbent in the recovery bottle 420. This can more effectively remove residual anesthetic gas, reduce the risk of gas leakage into the environment, and improve the safety of experimental operations.

[0049] And / or, the anesthesia device also includes a second interceptor disposed between the anesthesia bottle 410 and the second multi-port structure 220, for cutting off the downstream path of the anesthesia bottle 410, further reducing leakage of anesthetic gas into the environment, and reducing the risk of operator exposure to anesthetic gas.

[0050] Specifically, the second interceptor can also be a structure with both sealing and opening functions, such as a water-stop clamp. When anesthetic gas needs to be delivered, pressing the second interceptor opens it, allowing the anesthetic gas evaporating from the anesthetic bottle 410 to enter the second multi-port structure 220 through the silicone tube. When anesthetic gas delivery is not required (such as when anesthesia is paused or after the experiment), the second interceptor blocks the flow of anesthetic gas from the anesthetic bottle 410 to the second multi-port structure 220. Thus, even if anesthetic still evaporates from the anesthetic bottle 410, the second interceptor can directly block the diffusion of anesthetic gas to the second multi-port structure 220 and subsequent pipelines, further reducing the evaporation of anesthetic gas and more directly cutting off the downstream path of the anesthetic gas, which is beneficial to further improving the safety of the experimental environment.

[0051] refer to Figures 1 to 5 In some embodiments, the anesthesia device further includes a third throttling element; The anesthesia structure 310 includes multiple anesthesia masks 311, each of which is independently connected to a second multi-channel structure 220. A third interceptor is arranged between the second multi-channel structure 220 and the anesthesia mask 311. A recovery bottle 420 is connected to each anesthesia mask 311. This allows the gas passage of each anesthesia structure 310 to be independently adjusted, which is beneficial to improving the anesthesia flexibility of the anesthesia device.

[0052] Specifically, the third interceptor can also be a structure with both sealing and opening functions, such as a water-stop clamp. The anesthesia structure 310 may include an induction box 312 and multiple anesthesia masks 311. A third interceptor can be provided between the induction box 312 and the multi-pass structure, and between each anesthesia mask 311 and the multi-pass structure, so as to independently control the airflow into the induction box 312 and control the connection to the anesthesia masks 311.

[0053] The mixed anesthetic gas flows from the second multi-port structure 220 into the main inlet of the multi-port structure, and then is distributed to each branch through the outlet of the multi-port structure. When a particular anesthesia mask 311 needs to be used, the third shut-off device corresponding to that mask 311 is opened to open the pipeline, allowing the anesthetic gas to enter the mask 311 through the pipeline. If use needs to be suspended, the corresponding third shut-off device is closed, the pipeline is sealed, and the gas delivery is interrupted. Similarly, by operating the third shut-off device corresponding to the induction box 312, the supply of anesthetic gas to the induction box 312 can be independently controlled. The residual anesthetic gas discharged from each anesthesia mask 311 and the induction box 312 converges into the main pipeline through their respective branch pipelines and flows into the recovery bottle 420 to be absorbed by the adsorbent.

[0054] Alternatively, the anesthesia structure 310 includes an anesthesia mask 311 and an induction box 312. The anesthesia mask 311 and the induction box 312 are independently connected to the second multi-pass structure 220. A third interceptor is provided between the second multi-pass structure 220 and the anesthesia mask 311, and between the second multi-pass structure 220 and the induction box 312, so that the two passages of the anesthesia mask 311 and the induction box 312 are independent of each other, so as to ensure the flexibility of passage adjustment.

[0055] The following example further illustrates this application: In some examples, the first pump body 110 is a dual-port air pump, with its output end connected to silicone tubing with an inner diameter of 4mm and an outer diameter of 6mm. The second pump body 120 can be a water circulation pump, connected to silicone tubing with an inner diameter of 6mm and an outer diameter of 8mm. Airflow at other points is conducted using silicone tubing with an inner diameter of 5mm and an outer diameter of 7mm. Therefore, during anesthesia, only the anesthesia structure 310 needs to be removed from the storage box 510. The structures are pre-connected via silicone tubing, eliminating the need for connecting pipes and moving flow meters, making it more convenient to use. The power of the first pump body 110 is set to at least 5L / min, and the power of the second pump body 120 is 120L / h, or 2L / min. The capacity of the anesthesia bottle 410 can be 100ml, and the capacity of the recovery bottle 420 can be 250ml to ensure sufficient absorption of residual anesthetic gas.

[0056] The anesthesia mask can be made by cutting the bottom of a 20ml transparent square reagent bottle, which helps to reduce manufacturing costs. The first, second, and third flow-stopping parts can be silicone tube water-stopping clamps. A first flow meter 231 is provided between the first multi-port structure 210 and the second multi-port structure 220. A second flow meter 232 is provided between the anesthesia bottle 410 and the second multi-port structure 220. A third flow meter 233 is provided between the second multi-port structure 220 and each anesthesia structure 310. In addition, the anesthesia device of this application is lighter and easier to carry when manufactured using the above materials.

[0057] The anesthetized subjects can be mice and / or rats. When the subject is a mouse, the flow rate of the first flow meter 231 is 300-3000 ml / min, the flow rate of the second flow meter 232 is 10-100 ml / min, and the flow rate of the third flow meter 233 is 100-1000 ml / min. The flow parameters are controlled as follows (for the anesthesia mask 311): 300-500 ml / min for the first flow meter 231 and 10-15 ml / min for the second flow meter 232. Alternatively, if an induction chamber 312 is used, the flow parameters are controlled as follows: 300-500 ml / min for the first flow meter 231 and 30-45 ml / min for the second flow meter 232, to incorporate more anesthetic gas and ensure the anesthetic effect.

[0058] When the subject of anesthesia is a rat, the range of the second flow meter 232 can be changed to 15-160 ml / min, and the flow parameters are controlled as follows (anesthesia mask 311): 500-700 ml / min for the first flow meter 231 and 15-20 ml / min for the second flow meter 232. If the induction chamber 312 is used, the flow parameters are controlled as follows: 500-700 ml / min for the first flow meter 231 and 45-60 ml / min for the second flow meter 232, thus ensuring the same anesthetic effect.

[0059] When the subjects of anesthesia are mice and rats, the flow parameters for mice (anesthesia mask 311) are: 300-500 ml / min for the first flow meter 231 and 10-15 ml / min for the second flow meter 232. The flow parameters for rats (anesthesia mask 311) are: 500-700 ml / min for the first flow meter 231 and 15-20 ml / min for the second flow meter 232.

[0060] Furthermore, if the induction chamber 312 is used, the corresponding flow parameters for mice are: 300-500 ml / min for the first flow meter 231 and 30-45 ml / min for the second flow meter 232. The corresponding flow parameters for rats are: 500-700 ml / min for the first flow meter 231 and 45-60 ml / min for the second flow meter 232.

[0061] After anesthesia is administered, there is no need to disassemble the silicone tubing. It should be understood that the silicone tubing has elastic deformation properties, allowing the anesthesia structure 310 and the connected silicone tubing to be directly placed into the storage box 510. This allows the anesthesia structure 310, anesthesia bottle 410, recovery bottle 420, first pump body 110, second pump body 120, and each silicone tubing to be housed in the receiving cavity 511, making storage more convenient, lighter, and smaller. The entire anesthesia device can be moved by moving the storage box 510, making it more portable.

[0062] In summary, the anesthesia device of this application uses a second pump body 120 to actively recover residual anesthetic gas, which is beneficial to improving the waste gas recovery efficiency. On this basis, flow meters and flow cut-off devices are also installed in each gas passage. On the one hand, the proportion of anesthetic gas can be better controlled. On the other hand, each passage can independently control the gas flow and gas supply on / off, so as to ensure that the number of gas passages can be freely increased or decreased.

[0063] Furthermore, this application also places the flow meter on the outer peripheral wall of the storage box 510 for easy reading and assembly. After anesthesia is administered, the various structures can be stored away, and during use, they can be quickly connected via silicone tubing, making assembly more convenient. The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of this application. Moreover, in the absence of conflict, the embodiments and features described in the embodiments of this application can be combined with each other.
