Description

Technical Field

[0001] This invention relates to the field of anesthesia technology, specifically to a multifunctional device for inducing and maintaining inhaled anesthesia in multiple mice. Background Technology

[0002] In animal experiments, especially in pharmacology, toxicology, and neuroscience research, it is often necessary to administer inhalation anesthesia to mice and maintain it for extended periods. Currently, a common method of anesthesia involves placing the mouse in a sealed chamber and introducing fresh gas containing volatile anesthetics such as sevoflurane to induce and maintain anesthesia.

[0003] Existing anesthesia devices, such as a simple small animal anesthesia box designed by Kunming Medical University, mainly consist of a box body. An air inlet pipe is connected to the top of the box body, and a gas delivery pipe is fixedly connected to the top of the inner cavity. Multiple gas nozzles are connected at intervals to the bottom of the gas delivery pipe, and a solenoid valve is installed at the top of the air inlet pipe. An air outlet pipe and a suction hood are connected to one side of the box body. A vacuum pump sends waste gas into a gas recovery tank, where an adsorption medium treats the waste gas, allowing it to be discharged into the atmosphere.

[0004] However, in existing anesthesia devices, if the adsorption medium reaches saturation during waste gas recovery and treatment, it can no longer effectively adsorb harmful substances in the waste gas. The device must be shut down and the adsorption medium replaced before waste gas treatment can continue. This method makes it difficult to quickly replace the adsorption medium while simultaneously recovering and treating waste gas, resulting in limited waste gas treatment capacity, low treatment efficiency, and difficulty in continuously performing anesthesia and waste gas treatment, leading to low safety. Therefore, this invention provides a multifunctional inhalation anesthesia induction and maintenance device for multiple mice to solve the above problems. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides a multifunctional inhalation anesthesia induction and maintenance device for multiple mice. Through the design of the waste gas treatment branch, the adsorption medium can be replaced in real time during the waste gas recovery and treatment process, thereby effectively ensuring the continuous operation of anesthesia and waste gas treatment, improving the efficiency of waste gas treatment and the safety of anesthesia.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A multifunctional inhalation anesthesia induction and maintenance device for multiple mice includes a controller and a sealed box. The top of the sealed box has an insertion port for inserting mice, and the bottom of the sealed box is detachably connected to a sealing cap. A sealing component is provided at the insertion port for sealing the insertion port. An air intake component for inputting anesthetic gas is provided on one side of the sealed box. An exhaust pipe is connected to the other side of the sealed box, and a one-way exhaust valve is connected to the exhaust pipe where it connects to the sealed box. A waste gas treatment branch is provided on the side of the exhaust pipe away from the sealed box, and the waste gas treatment branch includes a double-unit soda lime tank and a double-unit activated carbon tank connected in series. The double-unit soda lime tank includes a first soda lime tank and a second soda lime tank connected to each other. The disodium lime tank and the first activated carbon tank are connected by a first reversing valve at their connection point; the dual activated carbon tank includes a first activated carbon tank and a second activated carbon tank that are connected to each other, and the connection point between the two is connected by a second reversing valve; the input end of the first reversing valve is connected to the exhaust pipe on the side away from the sealed chamber, and the output end of the second reversing valve is connected to a suction pump; the first disodium lime tank and the first activated carbon tank are connected to form a first processing path, and the second disodium lime tank and the second activated carbon tank are connected to form a second processing path; a controller is used to control the operation of the first reversing valve and the second reversing valve; a gas concentration monitoring component is installed inside the sealed chamber to monitor the concentration of various gases inside the sealed chamber, and the controller is used to adjust the operation of the suction pump according to the concentration of various gases.

[0007] The technical principle of the above solution is as follows:

[0008] Mice are placed into a sealed chamber through an inlet, which is then sealed using a sealing assembly. Anesthetic gas is continuously introduced into the chamber through an air intake assembly to anesthetize the mice. A suction pump continuously draws in the anesthetic gas, and the controller adjusts the pump's power based on the concentration of various gases to maintain the anesthetic gas levels within a specified range. During this process, the anesthetic gas sequentially enters the exhaust pipe and waste gas treatment branch through a one-way valve. The controller regulates the opening and closing of the first and second reversing valves, selectively directing the anesthetic gas into either the first or second treatment path. When the soda lime and activated carbon in the first path need replacement, the second treatment path is activated, and the soda lime and activated carbon in the first path are replaced; conversely, when the soda lime and activated carbon in the second path need replacement, the first treatment path is activated, and the soda lime and activated carbon in the second path are replaced. This alternating operation of the first and second treatment paths ensures continuous anesthesia and waste gas treatment.

[0009] The above approach has the following beneficial effects:

[0010] 1. This invention, through the design of a double-unit soda lime tank and a double-unit activated carbon tank, can quickly switch the treatment path of anesthetic gas without interrupting the process. The treatment medium in the device can be quickly replaced, allowing anesthesia and waste gas treatment to continue continuously, effectively improving the safety of anesthesia and the efficiency of waste gas treatment.

[0011] 2. This invention monitors the concentration of various gases inside a sealed chamber and dynamically adjusts the operating power of the suction pump based on the monitored gas concentrations. This ensures that the waste gas treatment work can be carried out reasonably while maintaining the concentration of anesthetic gas inside the sealed chamber within a specified range, thus guaranteeing the effectiveness and safety of the anesthesia work.

[0012] 3. This invention utilizes sodium lime and activated carbon to treat waste gas simultaneously, which can not only remove heptafluoroane from the waste gas, but also remove CO2 from the waste gas, ensuring that the final discharged gas meets the safety standards for carbon dioxide and anesthetic drug residues, and minimizing the impact of waste gas on the environment.

[0013] Furthermore, the air intake assembly includes an air intake pipe connected to one side of the upper part of the sealed box, a dispersion pipe connected to the top wall of the sealed box, and several through holes at the bottom of the dispersion pipe; the air intake pipe is connected to the dispersion pipe, and a one-way air intake valve is connected at the connection between the air intake pipe and the dispersion pipe; the dispersion pipe is in the shape of a zigzag line or a ring.

[0014] Beneficial effects: Unlike traditional single-hole direct-blowing air inlets, the zigzag or annular dispersion pipe of this invention divides a single stream of anesthetic gas into multiple low-speed and dispersed airflows through multiple through holes at the bottom, improving the consistency of anesthetic gas concentration in various locations within the sealed chamber, thereby ensuring uniform anesthesia depth in multiple mice.

[0015] Furthermore, the sealing assembly includes a sliding plate that slides laterally at the insertion port, the area of ​​which is larger than the area of ​​the insertion port.

[0016] Beneficial effects: As the sliding plate slides laterally, its edge gradually crosses the edge of the insertion port, making the open area of ​​the insertion port gradually change from small to large. The operator can place mice of different sizes and close the insertion port after placement to ensure the airtightness of the environment.

[0017] Furthermore, the gas concentration monitoring component includes several gas concentration sensors and temperature sensors embedded in the sealed enclosure. The gas concentration sensors are used to collect various gas concentration data and transmit the various gas concentration data to the controller. The gas concentration sensors include at least a carbon dioxide concentration sensor, an oxygen concentration sensor, and a heptafluoroane concentration sensor.

[0018] Beneficial effects: By collecting the concentration of various gases, this method facilitates the subsequent adjustment of the operating power of the suction pump by the controller, thereby regulating the concentration of various gases and ensuring the effectiveness and safety of anesthesia.

[0019] Furthermore, all corners of the inner wall of the sealed box are designed with rounded chamfers.

[0020] Beneficial effects: The smooth, rounded corner design makes it easier for operators to clean the sealed chamber. At the same time, the rounded corners eliminate sharp edges, preventing mice from getting skin abrasions, tail pinches, or limb entrapments due to collisions with right-angled edges, thus protecting the mice's safety and reducing abnormal experimental data caused by mouse injuries.

[0021] Furthermore, several operating holes are symmetrically opened on the side wall of the sealed enclosure, and operating gloves can be detachably connected to each operating hole.

[0022] Beneficial effect: Operators can perform specified operations on mice using operating gloves.

[0023] Furthermore, an air intake pump is connected to the side of the sealed enclosure near the air intake duct. An emergency stop button is installed on the sealed enclosure. The emergency stop button is used to close the one-way air intake valve and start the air intake pump.

[0024] Beneficial effects: This design, through the intake pump and emergency stop button, enables rapid dilution and replacement of gas in the sealed chamber, improving the survival rate and rescue success rate of laboratory mice in emergency situations, and enhancing the safety of the device.

[0025] Furthermore, several cable ports are opened on the lower side wall of the sealed enclosure, and each cable port is fixedly connected with a flexible sealing layer.

[0026] Beneficial effects: This solution, through the design of cable ports and flexible sealing layers, can ensure the normal use of various experimental equipment while maximizing the airtightness of the anesthesia environment.

[0027] Furthermore, an observation window is provided on the side wall of the sealed enclosure, and a transparent glass is fixedly connected to the observation window.

[0028] Beneficial effects: This solution, through the design of the observation window and transparent glass, allows the operator to observe the signs of anesthesia in mice in real time and clearly without damaging the seal of the box.

[0029] Furthermore, a display panel connected to the controller signal is fixedly connected to the top of the sealed enclosure. The display panel is used to display the concentration of various gases and the ambient temperature.

[0030] Beneficial effects: This solution, through the design of the display panel, allows operators to directly obtain the gaseous environment parameters inside the chamber. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0039] The following detailed description illustrates the specific implementation method:

[0040] Example 1:

[0041] like Figure 1 As shown, a multifunctional inhalation anesthesia induction and maintenance device for multiple mice includes a controller and a sealed box 1. The top of the sealed box 1 has an insertion port for inserting mice, and the bottom of the sealed box 1 is detachably fitted with a sealing bottom cover 8.

[0042] A rubber sealing ring is fitted on the sealing bottom cover 8 to improve the sealing performance of the device. Considering that heptafluoroane gas can easily cause rubber aging, the sealing ring on the sealing bottom cover 8 can be replaced. An insertion opening is provided on the sealing bottom cover 8, into which a heating plate of the prior art can be placed to adjust the ambient temperature.

[0043] like Figure 1 As shown, a sealing assembly for sealing the inlet is provided at the inlet; the sealing assembly includes a sliding plate 2 that is laterally slidably fitted at the inlet, and the area of ​​the sliding plate 2 is larger than the area of ​​the inlet.

[0044] Specifically, in the initial state, the sliding plate 2 completely seals the inlet. The operator can adjust the size of the inlet opening by sliding the sliding plate 2, thereby placing mice of different sizes into the sealed box 1. After the mice are placed in, the sliding plate 2 is reset to close the inlet.

[0045] like Figure 1 and Figure 2 As shown, several operating holes are symmetrically opened on the side wall of the sealed chamber 1, and operating gloves 16 can be detachably connected to each operating hole. An observation window is opened on the side wall of the sealed chamber 1, and a transparent glass 17 is fixedly glued to the observation window.

[0046] Specifically, after the mouse is placed in the sealed box 1, the operator can put their hands into the operating gloves 16, thereby performing the specified operation on the mouse in an isolated state and improving the safety of the operation.

[0047] like Figure 1 and Figure 2As shown, the lower side wall of the sealed box 1 has several cable ports 101, and each cable port 101 is fixedly bonded with a flexible sealing layer (a sealing rubber ring is used in this embodiment).

[0048] Specifically, the operator can select to place different experimental devices into the sealed chamber 1 according to the needs, such as electrode plates and temperature probes, and lead out the cables of these experimental devices through the cable port 101 to ensure that the experimental devices can operate normally; the flexible sealing layer can prevent the cables from repeatedly rubbing against the cable port 101, thereby protecting the cables, while also improving the sealing of the sealed chamber 1, reducing gas exchange, and ensuring the anesthetic effect.

[0049] like Figure 1 and Figure 4 As shown, a gas inlet assembly for inputting anesthetic gas is provided on one side of the sealed box 1. The gas inlet assembly includes a gas inlet pipe 5 connected to the upper side of the sealed box 1. A dispersion pipe 18 is connected to the inner top wall of the sealed box 1. Several through holes are opened at the bottom of the dispersion pipe 18. The gas inlet pipe 5 is connected to the dispersion pipe 18. A one-way gas inlet valve 4 is connected at the connection between the gas inlet pipe 5 and the dispersion pipe 18. The dispersion pipe 18 is in the shape of a broken line or a ring (a broken line shape is selected in this embodiment).

[0050] Specifically, in this embodiment, the air intake pipe 5 is connected to an anesthesia machine in the prior art. The anesthesia machine delivers anesthetic gas into the dispersion pipe 18 through the air intake pipe 5 and the one-way air intake valve 4, and delivers it to various positions in the sealed box 1 through the through hole, thereby improving the uniformity of the distribution of anesthetic gas concentration and ensuring that the anesthesia depth of multiple mice is uniform.

[0051] A gas concentration monitoring component is installed inside the sealed chamber 1. This component monitors the concentration of various gases inside the sealed chamber 1, and a controller adjusts the operation of the suction pump 15 based on the concentration of each gas. The gas concentration monitoring component includes several gas concentration sensors and temperature sensors embedded inside the sealed chamber 1. The gas concentration sensors collect data on the concentration of various gases and transmit this data to the controller. The gas concentration sensors include at least a carbon dioxide concentration sensor, an oxygen concentration sensor, and a heptafluoroane concentration sensor. Figure 1 As shown, a display panel 3, which is connected to the controller signal, is fixedly attached to the top of the sealed chamber 1. The display panel 3 is used to display the concentration of various gases and the ambient temperature. The operator can directly observe the various gas concentration parameters and the ambient temperature inside the sealed chamber 1 through the display panel 3.

[0052] Specifically, during anesthesia, the operator can adjust the operating power of the suction pump 15 via the controller as needed, thereby adjusting the rate at which gas is discharged from the device to the outside. In this embodiment, taking a specified sevoflurane concentration as an example, the operator inputs the desired sevoflurane concentration through the controller, which then adjusts the operating power of the suction pump 15. When the sevoflurane concentration in the sealed chamber 1 is higher than the desired concentration, the operating power of the suction pump 15 increases. Since the sevoflurane input rate remains constant while the output rate increases, the sevoflurane concentration in the sealed chamber 1 gradually decreases to the target concentration. When the sevoflurane concentration in the sealed chamber 1 is lower than the desired concentration, the operating power of the suction pump 15 decreases. Since the sevoflurane input rate remains constant while the output rate decreases, the sevoflurane concentration in the sealed chamber 1 gradually rises to the target concentration. This allows for the completion of anesthesia experiments under different specified environments.

[0053] This embodiment monitors the concentration of various gases inside the sealed chamber 1 and dynamically adjusts the operating power of the suction pump 15 based on the monitored gas concentrations. This ensures that the waste gas treatment work can be carried out reasonably while maintaining the concentration of anesthetic gas inside the sealed chamber within a specified range, thus guaranteeing the effectiveness and safety of the anesthesia work.

[0054] like Figure 1 and Figure 3 As shown, an exhaust pipe 10 is connected to the other side of the sealed chamber 1, and a one-way exhaust valve 9 is connected to the connection between the exhaust pipe 10 and the sealed chamber 1. A waste gas treatment branch is provided on the side of the exhaust pipe 10 away from the sealed chamber 1. The waste gas treatment branch includes a double-unit soda lime tank and a double-unit activated carbon tank connected in series. The double-unit soda lime tank includes a first soda lime tank 11 and a second soda lime tank 12 connected to each other, with a first reversing valve 19 connected at their connection point. The double-unit activated carbon tank includes a first activated carbon tank 13 and a second activated carbon tank 14 connected to each other, with a second reversing valve 20 connected at their connection point. The input end of the first reversing valve 19 is connected to the side of the exhaust pipe 10 away from the sealed chamber 1, and the output end of the second reversing valve 20 is connected to a suction pump 15. The first soda lime tank 11 and the first activated carbon tank 13 form a first treatment path, and the second soda lime tank 12 and the second activated carbon tank 14 form a second treatment path. The controller is used to control the operation of the first reversing valve 19 and the second reversing valve 20.

[0055] Specifically, in the initial state, the gas flow direction at the first reversing valve 19 is from the exhaust pipe 10 to the first soda lime tank 11, and the gas flow direction at the second reversing valve 20 is from the first activated carbon tank 13 to the suction pump 15.

[0056] In the initial stage of waste gas treatment (used anesthetic gas and gas produced by mouse respiration), the waste gas enters the exhaust pipe 10 through the one-way exhaust valve, and then enters the first soda lime tank 11 and the first activated carbon tank 13 through the exhaust pipe 10 and the first reversing valve 19 in sequence. The first soda lime tank 11 will adsorb CO2 in the waste gas, and the first activated carbon tank 13 will adsorb heptafluoroane in the waste gas. After the adsorption is completed, it is finally discharged to the outside through the suction pump 15, thus completing the waste gas treatment.

[0057] During the continuous waste gas treatment process, the soda lime in the first soda lime tank 11 and the activated carbon in the first activated carbon tank 13 will reach saturation. At this time, the operator can adjust the operating status of the first reversing valve 19 and the second reversing valve 20 through the controller, so that the gas flow direction at the first reversing valve 19 is from the exhaust pipe 10 to the second soda lime tank 12, and the gas flow direction at the second reversing valve 20 is from the second activated carbon tank 14 to the suction pump 15. The overall treatment path of the waste gas will change from the first treatment path to the second treatment path. During the treatment of the waste gas in the second treatment path, the operator can replace the soda lime in the first soda lime tank 11 and the activated carbon in the first activated carbon tank 13. Conversely, when the second treatment path reaches saturation, the operator can switch back to the first treatment path and replace the soda lime in the second soda lime tank 12 and the activated carbon in the second activated carbon tank 14.

[0058] This embodiment, through the design of the waste gas treatment branch, can not only recycle and treat waste gas, reducing its pollution to the environment, but also replace the adsorption medium in real time during the waste gas recycling process without interrupting the process. This effectively ensures the simultaneous and continuous operation of anesthesia and waste gas treatment, improving the efficiency of waste gas treatment and the safety of anesthesia.

[0059] Furthermore, this waste gas treatment method overcomes the technical drawback of existing technologies where the adsorption medium must be shut down and replaced after it becomes saturated, thus effectively extending the duration of a single experiment and providing the possibility for conducting more diverse anesthesia experiments.

[0060] Example 2:

[0061] Unlike the embodiments described above, as Figure 1 As shown, the corners of the inner wall of the sealed box 1 are all designed with rounded chamfers.

[0062] Specifically, the smooth, rounded corner design makes it easier for operators to clean the sealed chamber 1. At the same time, the rounded corners eliminate sharp edges, preventing mice from getting skin abrasions, tail pinches, or limb entrapments due to collisions with right-angled edges, thus protecting the safety of the mice and reducing abnormal experimental data caused by mouse injuries.

[0063] Example 3:

[0064] Unlike the embodiments described above, as Figure 1 As shown, the sealed box 1 is also connected to the intake pump 6 on the side near the intake duct. An emergency stop button 7 is installed on the sealed box 1. The emergency stop button 7 is used to close the one-way intake valve 4 and turn on the intake pump 6.

[0065] Specifically, in the initial state, when the emergency stop button 7 is not triggered, the one-way air intake valve 4 is in the normally open state, the air intake pump 6 is in the power-off closed state, and the anesthetic gas is normally input into the sealed chamber 1 from the external anesthesia machine through the air intake pipe 5 and the one-way air intake valve 4; when the emergency stop button 7 is pressed and triggered, the one-way air intake valve 4 receives the control signal and closes instantly, cutting off the passage of anesthetic gas from the air intake pipe 5 into the distribution pipeline, and at the same time the air intake pump 6 is powered on and starts, continuously pumping fresh air or pure oxygen into the sealed chamber 1 (the gas source depends on the laboratory gas source configuration, and can be indoor air after high-efficiency filtration, or connected to the oxygen cylinder in the existing technology).

[0066] This embodiment, through the design of the air intake pump 6 and the emergency stop button 7, can quickly dilute and replace the gas in the sealed chamber 1, thereby improving the survival rate and rescue success rate of experimental mice in emergency situations and enhancing the safety of the anesthesia process.

[0067] Example 4:

[0068] Unlike the embodiments described above, as Figure 1 and Figure 3 As shown, a heptafluoroane gas concentration monitor is installed at the output end of the suction pump. Users can set the minimum treatment standard for heptafluoroane gas concentration through the display panel 3. If the concentration of the discharged exhaust gas exceeds the minimum treatment standard, the display panel 3 will issue a prompt to provide an early warning.

[0069] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
