Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] It should also be understood that the terminology used in this specification is merely for describing specific realities within the context of this application. It is important to understand that terms such as "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are used solely for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0043] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0044] like Figures 1 to 11 As shown, this application provides an anesthesia machine, which includes an anesthesia machine main unit 100, a display, a breathing circuit 200, a drive module 300, a body column 500, and a mounting platform 600. The display is mounted on the anesthesia machine main unit 100, the breathing circuit 200 is mounted on the mounting platform 600, and both the drive module 300 and the mounting platform 600 are mounted on the body column 500. The drive module 300 is positioned no higher than the position of the breathing circuit 200 on the mounting platform or the position on the body column of the mounting platform. The anesthesia machine main unit 100 is connected to the mounting platform 600 or the body column 500 so that the body column 500 can support the anesthesia machine main unit. All or all of the anesthesia machine main unit 100 except for the mounting mating position is located above the mounting platform. The breathing circuit 200 can be mounted on the body column 500 via the mounting platform 600. The breathing circuit 200 includes a volume exchange device 201, and the drive module 300 is used to provide drive gas to the volume exchange device 201 so that the volume exchange device 201 can provide ventilation airflow to the patient.

[0045] In some embodiments, the flow meter panel of the anesthesia machine is disposed on the main unit 100 of the anesthesia machine, and the position of the flow meter panel on the main unit 100 is no lower than the position of the drive module 300 on the machine body column 500. The flow meter panel may include a first panel and a second panel facing the operator of the anesthesia machine. The first panel is provided with a first functional component, and the second panel may be provided with a second functional component. The first functional component includes at least a main flow control selector and an auxiliary flow control selector. The main flow control selector is used to regulate the flow rate of fluid from a first fluid input end flowing through the first flow control valve, for example, to regulate the flow rate of fluid supplied to the patient via the breathing circuit. The auxiliary flow control selector is used to regulate the flow rate of fluid from a second fluid input end flowing through the second flow control valve to meet actual clinical needs. The second panel may have a first area and a second area. A panel mounting position is provided on the second area, and the first panel is detachably mounted on the panel mounting position. The first panel and the second panel may also be two independent panels, jointly mounted on the side of the main unit 100 of the anesthesia machine facing the operator.

[0046] Specifically, in machine-controlled mode, when the patient exhales, the exhaled gas enters the volume exchange device 201 along the tubing of the breathing circuit 200 and is stored. When the patient inhales, the drive module 300 controls a certain flow rate and pressure of driving gas into the volume exchange device 201, and pushes the gas within the volume exchange device 201 to drive the anesthesia machine to provide continuous gas to the patient. The breathing circuit 200 also includes a carbon dioxide absorption canister. When the patient exhales, the exhaled gas enters the carbon dioxide absorption canister, which removes carbon dioxide before mixing it with fresh gas carrying anesthetic gas and oxygen before entering the patient's lungs, thus completing one respiratory cycle.

[0047] The volume exchange device 201 can be a bellows assembly. The pleated bag within the bellows assembly stores a certain amount of gas containing anesthetic components during the patient's inhalation and exhalation. Specifically, when the patient exhales, the exhaled gas enters the pleated bag along the breathing tube, causing it to rise. When the patient inhales, the drive module 300 controls a certain flow rate and pressure of driving gas to enter the bellows assembly. This driving gas pushes the pleated bag downwards, expelling the gas inside. The gas then flows through a carbon dioxide absorption canister to filter out carbon dioxide, and finally mixes with fresh gas carrying anesthetic gas and oxygen before entering the patient's lungs, completing one respiratory cycle.

[0048] Alternatively, the volume exchange device 201 can be a volume reflector. When the patient exhales, the exhaled air enters the volume reflector along the breathing tubing and is stored there. Simultaneously, the volume reflector expels excess air. When the patient inhales, the drive module 300 controls a certain flow rate and pressure of driving gas to enter the volume reflector and push the air inside, thus expelling the air from the volume reflector. The gas then flows through a carbon dioxide absorption canister to filter out carbon dioxide, and is mixed with fresh gas carrying anesthetic gas and oxygen before entering the patient's lungs, completing one respiratory cycle.

[0049] In an optional embodiment, the mounting platform 600 includes one of a first mounting platform 601 and a second mounting platform 602. The first mounting platform 601 and the second mounting platform 602 share at least the characteristic that they can be used to mount a breathing circuit. The difference lies in that the second mounting platform 602 has a work surface 6021, which refers to a surface used as an operating area or a place for storing items, such as for placing instruments or for the doctor to make surgical records during use; the first mounting platform 601 does not have a work surface used as an operating area or a place for storing items, or even if the second mounting platform 601 has an area extending towards the front of the anesthesia machine (i.e., the side facing the user), this area cannot support the installation of a drawer. The first mounting platform 601 and the second mounting platform 602 are provided with platform mounting parts, and the body column 500 is provided with a support part. The first mounting platform 601 or the second mounting platform 602 is mounted on the support part through the platform mounting parts, and the anesthesia machine main unit 100 is mounted on the first mounting platform 601 or the second mounting platform 602; or, the support part has a first mounting area and a second mounting area, the first mounting platform 601 or the second mounting platform 602 is mounted on the first mounting area through the platform mounting parts, and the anesthesia machine main unit 100 is mounted on the second mounting area.

[0050] refer to Figure 1 In this embodiment, when the mounting platform 600 is the second mounting platform 602, the anesthesia machine main unit 100 is mounted on the second mounting platform 602, which is then connected to the machine body column 500. The worktable 6021 is located on the side of the machine body column 500 facing the user. The drive module is located inside the machine body column 500 and is mounted in a lower position relative to the second mounting platform or the worktable, that is, the drive module is positioned no higher than the position of the second mounting platform on the machine body column or below the worktable.

[0051] refer to Figure 2 In this embodiment, when the mounting platform 600 is the first mounting platform 601, both the anesthesia machine main unit 100 and the first mounting platform 601 are mounted on the machine body column 500. Although the first mounting platform 601 in this embodiment has an extended area facing the front of the anesthesia machine, this area is neither a work surface used as an operating area or a storage area, nor can it be used to install drawers. The drive module is located within the machine body column 500 and is positioned lower than the location where the first mounting platform or the breathing circuit is mounted on the first mounting platform; that is, the drive module is positioned no higher than the location of the first mounting platform on the machine body column or the location where the breathing circuit is mounted on the first mounting platform.

[0052] Although the first and second mounting platforms in this application are described as being mounted on the main frame, this description does not limit the first and second mounting platforms to being separate components independent of the main frame and the anesthesia machine host. The first and second mounting platforms in this application can be separate components separate from the main frame and the anesthesia machine host, and then mounted on the main frame via a specific connection method when assembled into the anesthesia machine; or they can be integral with the main frame, and a portion thereof defined within that integral part, in which case the mounting can be, for example, integrally formed or with an irreversible connection and fixing method; or they can be integral with the anesthesia machine host, and a portion thereof defined within that integral part, and then mounted on the main frame via a specific connection method when assembled into the anesthesia machine.

[0053] In an optional embodiment, a drive mounting section 501 is provided on the body column 500. The height of the drive mounting section 501 is lower than the height of the mounting platform 600, so that the drive module 300 can be mounted on the body column 500 and located in the lower part of the anesthesia machine. When the drive module 300 is located in the lower part of the body column, the anesthesia machine does not need to increase the volume of the mounting platform to accommodate the drive module, nor does it need to increase the volume of the anesthesia machine main unit. This reduces the overall width of the anesthesia machine. The overall component layout of the anesthesia machine is more balanced, making the overall structure of the anesthesia machine more compact and small. In addition, when the drive module is installed in the body column, whether the volume of the anesthesia machine's mounting platform can accommodate the drive module no longer affects the overall layout design of the anesthesia machine. The drive module is installed on the drive mounting section in an integral disassembly and assembly manner. For example, the drive module may include a first bracket. Each component is first set on the first bracket, and then the first bracket, with each component already installed, is installed into the body column to achieve integral installation. During disassembly, the first bracket can be disconnected from the body column first, and then the specific components connected to the first bracket can be removed.

[0054] Specifically, the first mounting platform 601 or the second mounting platform 602 each has an upper end face and a lower end face that are arranged opposite to each other. The volume exchange device 201 is installed on the upper end face, and the carbon dioxide absorption tank is installed on the lower end face. When the first mounting platform 601 or the second mounting platform 602 is installed on the body column 500, the volume exchange device 201 faces the side (upper side) of the anesthesia machine host 100, and the carbon dioxide absorption tank is located on the opposite side (lower side) relative to the volume exchange device. The drive module 300 is installed on the body column 500 at a position lower than the volume exchange device 201.

[0055] In an optional embodiment, the workbench 6021 may be part of the second mounting platform 602. The breathing circuit 200 is disposed on the second mounting platform 602 and located on one side of the workbench 6021. The second mounting platform 602 is mounted on the machine body column 500. The anesthesia machine main unit 100 is mounted on the second mounting platform 602 and located above the workbench 6021. The machine body column 500 is provided with a drive mounting part 5011 at a position not higher than the workbench 6021. When the drive module 300 is mounted on the drive mounting part 501, it is not higher than the position on the workbench mounted on the anesthesia machine main unit 100, which makes the arrangement, installation and removal of the drive module 300 convenient and flexible.

[0056] For example, the anesthesia machine also includes a display screen, which is connected to the anesthesia machine host 100 and located above the mounting platform; the machine body column 500 is located below the anesthesia machine host 100 and serves to support the anesthesia machine host 100 and the display screen.

[0057] In an optional implementation, the drive module 300 includes one of an electronically controlled drive module 301 and a pneumatic drive module 302. The electronically controlled drive module 301 and the pneumatic drive module 302 can be interchanged on the drive mounting part 501. Specifically, the selection can be made according to the functional requirements of the anesthesia machine, thereby effectively realizing the interchangeability between the electronically controlled drive module 301 and the pneumatic drive module 302, and greatly reducing the labor intensity of modifying the anesthesia machine host 100.

[0058] Among them, the anesthesia machine that uses an electronically controlled drive module 301 to control the driving gas is the electric version, and the anesthesia machine that uses a pneumatically controlled drive module 302 to control the driving gas is the pneumatic version. The electric and pneumatic versions of the anesthesia machine have different advantages in use, and the differences are significant. Furthermore, anesthesia machines of the same model cannot be simultaneously compatible with both electric and pneumatic versions; they must either only have an electronically controlled drive module 301 or only a pneumatically controlled drive module 302. Moreover, due to the different drive methods, the overall structural layout of the electric and pneumatic versions of the anesthesia machine also differs significantly; it is not possible to easily convert an anesthesia machine from electronically controlled to pneumatically controlled (and vice versa).

[0059] For example, when the drive module 300 inside the anesthesia machine is an electronically controlled drive module 301, the electronically controlled drive module 301 uses a turbine to control the flow rate and pressure of drive gas into the volume exchange device 201, and pushes the gas inside the volume exchange device 201. When the drive module 300 inside the anesthesia machine is a pneumatic drive module 302, the pneumatic drive module 302 uses an exhalation valve 3012 to control the flow rate and pressure of drive gas into the volume exchange device 201, and pushes the gas inside the volume exchange device 201.

[0060] However, existing methods differentiate between pneumatic and electric anesthesia machines based on their overall structure, resulting in significantly different overall designs and making it impossible to switch between them after the machines leave the factory. This application addresses this by using a drive mounting section 501 that accommodates both the electronic drive module 301 and the pneumatic drive module 302. This allows for interchangeability between the two modules on the drive mounting section 501, and facilitates the removal of the electronic drive module 301 and pneumatic drive module 302 from the machine body column 500. This enables convenient switching between the pneumatic and electric versions of the anesthesia machine and also simplifies assembly and maintenance. Meanwhile, the drive installation unit can unify the installation position of the electronic drive module 301 or the pneumatic drive module 302, setting the electronic drive module 301 or the pneumatic drive module 302 at a position where the machine body column 500 is not higher than the installation platform (or the installation position of the breathing circuit 200), that is, integrating the electronic drive module 301 or the pneumatic drive module 302 into the lower part of the anesthesia machine. This allows the anesthesia machine main unit 100 or the installation platform to be made smaller, which helps to miniaturize the design of the anesthesia machine.

[0061] In an optional embodiment, the anesthesia machine further includes a transfer structure 400 disposed in the body column 500. The transfer structure 400 is detachably connected to the drive module 300 and serves to connect the drive module 300 and the volume exchange device 201. The interface on the transfer structure 400 for connecting to the drive module 300 is configured to be usable for both electronically controlled drive module 301 and pneumatically controlled drive module 302. The transfer structure 400 provides a transfer between the volume exchange device 201 and the drive module 300 (pneumatically controlled drive module 302 or electronically controlled drive module 301), allowing for easy interchangeability of the two different drive modules 300 within a single anesthesia machine model, reducing the economic costs associated with design changes to accommodate different drive modules 300.

[0062] In an optional embodiment, the drive mounting part 501 includes a receiving groove disposed within the body column 500. The structure of the receiving groove is adapted to the structure of the electronic drive module 301 and the pneumatic drive module 302, so that the electronic drive module 301 and the pneumatic drive module 302 can be respectively housed in the receiving groove. This allows the overall structure of the electronic drive module 301 or the pneumatic drive module 302 to be hidden within the body column 500, greatly reducing the size of the anesthesia machine and improving its overall aesthetics. At the same time, it can also effectively protect the electronic drive module 301 or the pneumatic drive module 302.

[0063] In an optional embodiment, the electronic drive module 301 and the pneumatic drive module 302 are interchangeable on the drive mounting part 501 in an integral disassembly and assembly manner, which can effectively reduce the labor intensity of assembling the electronic drive module 301 and the pneumatic drive module 302 and shorten the installation time of the electronic drive module 301 and the pneumatic drive module 302.

[0064] In an optional embodiment, both the electrically controlled drive module 301 and the pneumatic drive module 302 are provided with an inspiratory channel outlet 300a, an expiratory channel inlet 300b, and an expiratory channel outlet 300c. These three outlets are located on the same side of the drive module 300 and face the volume exchange device 201, for connection to the volume exchange device 201. The volume exchange device 201 can communicate with the drive module 300 via a transfer structure 400, allowing the drive module 300 to control the flow rate and pressure of driving gas into the volume exchange device 201 and propel the gas within it, providing gas output to the patient.

[0065] The inspiratory channel outlet 300a, expiratory channel inlet 300b, and expiratory channel outlet 300c are positioned on the same side, facilitating their connection to the volume exchange device 201. This can be achieved by connecting them via a loop pipe, or by using a component similar to the transfer structure 400 to integrate them with the volume exchange device 201. Alternatively, the transfer structure 400 can be integrally formed with the inspiratory channel outlet 300a, expiratory channel inlet 300b, and expiratory channel outlet 300c, and then the volume exchange device 201 can be connected to them.

[0066] Since both the electronically controlled drive module 301 and the pneumatic drive module 302 are equipped with an inhalation channel outlet 300a, an expiratory channel inlet 300b, and an expiratory channel outlet 300c, and these three components are located on the same side and face the volume exchange device 201, an anesthesia machine of one model can easily achieve interchangeability between the two different drive modules 300, namely the electronically controlled drive module 301 and the pneumatic drive module 302, reducing the economic costs caused by design changes to the anesthesia machine to accommodate different drive modules 300. For example, the electronically controlled drive module 301 is connected to the volume exchange device 201 on the breathing circuit 200 through the inspiratory channel outlet 300a, the expiratory channel inlet 300b, and the expiratory channel outlet 300c. When it is necessary to replace the electronically controlled drive module 301 with the pneumatic drive module 302, the pneumatic drive module 302 can be directly replaced in the anesthesia machine. Similarly, the pneumatic drive module 302 can be connected to the volume exchange device 201 on the breathing circuit 200 through the inspiratory channel outlet 300a, the expiratory channel inlet 300b, and the expiratory channel outlet 300c, thus solving the problem that the structural layout of an anesthesia machine cannot support the interchangeability of two drive modules 300.

[0067] In one alternative implementation, such as Figure 9 and Figure 10 As shown, the transfer structure 400 includes a driving gas inlet 400a, an exhalation valve inlet 400b, and an exhalation valve outlet 400c. The driving gas inlet 400a is connected to the inhalation channel outlet 300a, the exhalation valve inlet 400b is connected to the exhalation channel inlet 300b, and the exhalation valve outlet 400c is connected to the exhalation channel outlet 300c, so as to reduce intermediate connecting pipes and improve the convenience of assembly operations.

[0068] In an alternative embodiment, the drive air inlet 400a, the exhalation valve inlet 400b, and the exhalation valve outlet 400c are located on the same side of the transfer structure 400 and are positioned toward the drive module 300 so that they can be connected to the drive module 300.

[0069] In an optional embodiment, the transfer structure 400 is further provided with an expiratory inlet 4021 and a driving gas outlet 4022. The expiratory inlet 4021 and the driving gas outlet 4022 are located on the same side of the transfer structure 400 and are arranged facing the volume exchange device 201. They are used to connect with the volume exchange device 201, so that the volume exchange device 201 can be connected to the driving module 300 through the transfer structure 400. This allows the driving module 300 to control the driving gas at a certain flow rate and pressure to enter the volume exchange device 201 and push the gas in the volume exchange device 201 to provide gas output for the patient.

[0070] In an optional embodiment, the transfer structure 400 is further provided with an APL exhaust port 4023 on the same side as the expiratory inlet 4021 or the driving gas outlet 4022, for connecting to the APL valve in the anesthesia machine, so that the gas discharged from the APL valve can be discharged from the APL exhaust port 4023, thereby controlling the gas pressure of the respiratory system in the anesthesia machine, so that the pressure of the patient's inhaled gas can be adjusted through the APL valve.

[0071] For example, the transfer structure 400 is also provided with an exhaust pipe 403. The exhaust pipe 403 can be located on the opposite side of the exhalation inlet 4021 and the driving gas outlet 4022, and the exhaust pipe 403 is connected to the APL exhaust port 4023 to discharge the gas discharged from the APL valve. For example, when the anesthesia machine is in manual mode, the gas discharged from the APL valve will enter through the APL exhaust port 4023 and then be discharged through the exhaust pipe 403, realizing pressure regulation of the respiratory system in manual mode.

[0072] In an optional embodiment, the transfer structure 400 further includes a first pipeline with an exhaust outlet, the first pipeline being connected to the APL exhaust port 4023, the exhalation valve outlet 400c and the exhaust pipe 403; wherein, a negative pressure valve 405 is provided in the first pipeline, the valve outlet of the negative pressure valve 405 being connected to the first pipeline, for balancing the internal pressure in the first pipeline.

[0073] The exhaust pipe 403 has a first port 4031 and a second port. The first port 4031 is connected to the anesthetic gas purification system, and the second port is connected to the exhaust outlet, allowing the anesthetic gas purification system to continuously draw exhaust gas from the anesthesia machine. If the exhalation valve or APL valve is blocked, the internal pressure of the anesthesia machine will be too low, preventing further exhaust gas extraction. At this time, the negative pressure valve 405 opens, allowing external air to enter the first pipe to balance the internal pressure of the anesthesia machine and prevent excessive negative pressure in the internal pipes from damaging internal components.

[0074] In an optional embodiment, the transfer structure 400 includes a first fixing member 401, a connecting member 404, and an adapter member 402. The connecting member 404 has the aforementioned driving gas inlet 400a, the aforementioned expiratory valve inlet 400b, and the aforementioned expiratory valve outlet 400c. The adapter member 402 has the aforementioned expiratory inlet 4021 and the aforementioned driving gas outlet 4022. The connecting member 404 is connected to the adapter member 402. The first fixing member 401 is disposed on the side of the connecting member 404 facing the driving module 300 and is used to fix it to the anesthesia machine body.

[0075] In an optional embodiment, the first fixing member 401 is floatingly connected to the connecting member 404, that is, there is a certain amount of movement between the driving air inlet 400a, the exhalation valve inlet 400b, and the exhalation valve outlet 400c and the first fixing member 401, so as to avoid air leakage at the connection due to the accumulation of tolerances when the driving air inlet 400a, the exhalation valve inlet 400b, and the exhalation valve outlet 400c are connected to the inhalation channel outlet 300a, the exhalation channel inlet 300b, and the exhalation channel outlet 300c.

[0076] For example, the first fixing member 401 is provided with a first through hole 4011 and a second through hole 4012. The outer flange of the driving air inlet 400a is clearance-fitted with the first through hole 4011, and the outer flanges of the exhalation valve inlet 400b and the exhalation valve outlet 400c are clearance-fitted with the second through hole 4012, so as to allow the driving air inlet 400a, the exhalation valve inlet 400b and the exhalation valve outlet 400c to have vertical and horizontal floating gaps relative to the first through hole 4011 and the second through hole 4012.

[0077] In one optional implementation, the drive module 300 includes either a pneumatic drive module 302 or an electronically controlled drive module 301; wherein the transfer structure 400 is further provided with at least one of a PEEP exhaust inlet and an expiratory pressure monitoring port, the PEEP exhaust inlet being used to connect to the pneumatic drive module 302, and the expiratory pressure monitoring port being used to monitor the expiratory pressure of the electronically controlled drive module 301.

[0078] Specifically, when the drive module 300 is a pneumatic drive module 302, the PEEP exhaust port is connected to the pneumatic drive module 302, and the transfer structure 400 is not equipped with an expiratory pressure monitoring port, or the expiratory pressure monitoring port on the transfer structure 400 is not connected to the outside; or, when the drive module 300 is an electronically controlled drive module 301, the expiratory pressure monitoring port is used to monitor the expiratory pressure of the electronically controlled drive module 301, and the transfer structure 400 is not equipped with a PEEP exhaust port, or the PEEP exhaust port on the transfer structure 400 is not connected to the outside.

[0079] In an optional embodiment, the volume exchange device 201 is disposed at the upper part of the anesthesia machine, the drive module 300 is disposed at the lower part of the anesthesia machine, and the transfer structure 400 includes a gas channel extending along the upper and lower sides of the anesthesia machine for communicating the drive module 300 located at the lower part of the anesthesia machine with the volume exchange device 201 located at the upper part of the anesthesia machine, so that the drive module 300 can drive the volume exchange device 201 to move, and the volume exchange device 201 can provide a continuous airflow to the patient to ensure the continuity of ventilation.

[0080] The placement of the volume exchange device 201 at the top of the anesthesia machine and the drive module 300 at the bottom contributes to the miniaturization and integration of the anesthesia machine, allowing it to adapt to smaller operating environments and improving its flexibility. Furthermore, the transfer structure 400 includes gas channels extending along the top and bottom of the anesthesia machine for connecting the drive module 300 and the volume exchange device 201. This reduces the need for piping between the drive module 300 and the volume exchange device 201, and also allows for a reduction in the size of the upper part of the anesthesia machine, thereby minimizing its impact on the overall weight and center of gravity.

[0081] In an optional embodiment, the capacity exchange device 201, the transfer structure 400, and the drive module 300 are sequentially arranged in the lateral direction of the anesthesia machine. The interface of the transfer structure 400 for connecting with the drive module 300 is located on the same side of the transfer structure 400 and faces the drive module 300. The interface of the transfer structure 400 for connecting with the capacity exchange device 201 is located on the same side of the transfer structure 400 and faces the capacity exchange device 201. This reduces intermediate connecting pipes, supports the overall disassembly and assembly of the whole machine during assembly, and realizes the modular design of the capacity exchange device 201, the transfer structure 400, and the drive module 300, resulting in a compact structure.

[0082] In an optional implementation, the interface of the transfer structure 400 for connecting with the drive module 300 is floatingly connected to the fuselage column 500. That is, a certain amount of movement is left between the drive air inlet 400a, the exhalation valve inlet 400b, and the exhalation valve outlet 400c and the fuselage column 500 to avoid air leakage at the connection due to accumulated tolerances when the drive air inlet 400a, the exhalation valve inlet 400b, and the exhalation valve outlet 400c are connected to the inhalation channel outlet 300a, the exhalation channel inlet 300b, and the exhalation channel outlet 300c.

[0083] In an optional embodiment, the drive module 300 includes a first bracket 3014 for detachable connection with the drive mounting part 501. At least two of the inspiratory channel outlet 300a, expiratory channel inlet 300b, and expiratory channel outlet 300c are distributed at different heights on the first bracket 3014. That is, at least two of the inspiratory channel outlet 300a, expiratory channel inlet 300b, and expiratory channel outlet 300c have a certain vertical height difference at their positions on the first bracket 3014 and are not on the same plane. This allows the inspiratory channel outlet 300a, expiratory channel inlet 300b, and expiratory channel outlet 300c to be distributed in a three-dimensional space. Compared with the planar distribution of the inspiratory channel outlet 300a, expiratory channel inlet 300b, and expiratory channel outlet 300c, this arrangement can make more efficient use of space and reduce the space occupied in the anesthesia machine.

[0084] In an optional embodiment, the drive module 300 includes an expiratory valve 3012 for discharging excess gas from the volume exchange device 201. The expiratory valve 3012 has an expiratory channel inlet 300b and an expiratory channel outlet 300c. The expiratory channel inlet 300b and the expiratory channel outlet 300c are distributed at different heights relative to the inspiratory channel outlet 300a on the first support 3014. This arrangement is more efficient in utilizing space than a planar distribution and also reduces the space occupied by the expiratory valve 3012 in the anesthesia machine.

[0085] In one alternative implementation, such as Figures 6 to 8 As shown, the first support 3014 has at least two first loading positions 30141 and second loading positions 30142 spaced apart along the height direction, so that the inspiratory channel outlet 300a, expiratory channel inlet 300b, and expiratory channel outlet 300c can be sequentially distributed in the first loading positions 30141 and second loading positions 30142. The expiratory valve 3012 is disposed on the first loading position 30141, with the expiratory channel inlet 300b and expiratory channel outlet 300c distributed in the first loading position 30141, and the inspiratory channel outlet 300a distributed in the second loading position 30142. When the drive module 300 is installed in the receiving slot, the inspiratory channel outlet 300a, expiratory channel inlet 300b, and expiratory channel outlet 300c can be installed along the height direction of the anesthesia machine and correspondingly connected to the drive gas inlet 400a, expiratory valve inlet 400b, and expiratory valve outlet 400c on the transfer structure 400.

[0086] In an optional embodiment, the electronically controlled drive module 301 includes a turbine box 3011, an inhalation valve 3013, and an exhalation valve 3012. The turbine box 3011 is connected to the volume exchange device 201 through an exhalation channel inlet 300b and an inhalation channel outlet 300a. The turbine box 3011 is used to generate driving gas during inhalation, so that the driving gas can be input into the volume exchange device 201 after passing through the inhalation valve 3013 and the inhalation channel outlet 300a. The gas in the volume exchange device 201 is discharged after entering the exhalation valve 3012 through the exhalation channel inlet. The intake valve 3013 is equipped with a first voice coil motor, which works in conjunction with the turbine housing 3011 to control the flow rate of the driving gas flowing out of the intake valve 3013. This not only eliminates the need for an external air source, allowing the driving gas to be generated directly through the turbine housing 3011 without consuming additional external air sources, thus reducing operating costs, but also enables more efficient and accurate control of the driving gas flow rate by coordinating the turbine speed of the turbine housing 3011 with the first voice coil motor.

[0087] In an optional embodiment, the drive module 300 further includes a first bracket 3014 for detachable connection with the drive mounting portion 501. The first bracket 3014 has adjacent first end face, second end face and third end face. A first mounting portion is provided on the first end face, a second mounting portion is provided on the second end face and a third mounting portion is provided on the third end face. The turbine box 3011, the exhalation valve 3012 and the inhalation valve 3013 are respectively mounted on the first mounting portion, the second mounting portion and the third mounting portion.

[0088] For example, the first bracket 3014 has adjacent first end face, second end face, and third end face. A first mounting portion is disposed on the first end face, a second mounting portion is disposed on the second end face, and a third mounting portion is disposed on the third end face. Specifically, the first mounting portion is a first recessed groove on the first end face, the third mounting portion is a second recessed groove on the second end face, and the third mounting portion is a third recessed groove on the third end face. The turbine housing 3011 is fitted into the first recessed groove, the exhalation valve 3012 is fitted into the second recessed groove, and the inhalation valve 3013 is fitted into the third recessed groove.

[0089] In an optional embodiment, the electronically controlled drive module 301 further includes a cooling fan 315. The first bracket 3014 is connected to a first mounting bracket 30143, which has a mounting groove. A limiting member is provided on the side wall of the mounting groove. The limiting member is used to guide the cooling fan 315 to be installed in the mounting groove, so that the cooling fan 315 can dissipate heat from the electronically controlled drive module 301. At the same time, the limiting member enables the cooling fan 315 to be installed with one hand, eliminating the need to hold the cooling fan 315 with one hand and operate the fixing screws with the other, thus improving the assembly efficiency of the cooling fan 315.
