[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] It should also be understood that the terms used in this specification of the present invention are only for describing specific realities. In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0043] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0044] like Figures 1 to 11 As shown, the present application provides an anesthesia machine, which includes an anesthesia machine main unit 100, a display, a breathing circuit 200, a drive module 300, a fuselage column 500 and a mounting platform 600, wherein the display is mounted on the anesthesia machine main unit 100, the breathing circuit 200 is mounted on the mounting platform 600, the drive module 300 and the mounting platform 600 are both mounted on the fuselage column 500, and the setting position of the drive module 300 is not higher than the position where the breathing circuit 200 is installed on the mounting platform or is not higher than the position on the fuselage column of the mounting platform. The anesthesia machine main unit 100 is connected to the mounting platform 600 or the fuselage column 500 so that the fuselage column 500 can support the anesthesia machine main unit. All or part of the anesthesia machine main unit 100 except the mounting matching position is located above the mounting platform. The breathing circuit 200 can be mounted on the fuselage column 500 through the mounting platform 600. The breathing circuit 200 has a capacity exchange device 201, and the driving module 300 is used to provide driving gas to the capacity exchange device 201, so that the capacity exchange device 201 can provide ventilation airflow for the patient.

[0045] In some embodiments, the flow meter panel of the anesthesia machine is arranged on the anesthesia machine mainframe 100, and the setting position of the flow meter panel on the anesthesia machine mainframe 100 is not lower than the setting position of the drive module 300 on the fuselage 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. Among them, the first functional component at least includes a main flow control selector and an auxiliary flow control selector. The main flow control selector is used to adjust the flow of the fluid from the first fluid input end flowing through the first flow control valve, for example, for adjusting the flow of the fluid provided to the patient through the breathing circuit. The auxiliary flow control selector is used to adjust the flow of the fluid from the second fluid input end flowing through the second flow control valve to meet the 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 can be detachably mounted on the panel mounting position. The first panel and the second panel may also be two independent panels, which are installed together on the side of the anesthesia machine mainframe 100 facing the operator.

[0046] Specifically, in the machine control mode, when the patient exhales, the gas exhaled by the patient enters the capacity exchange device 201 along the pipeline of the breathing circuit 200 and is stored; when the patient inhales, the driving module 300 controls the driving gas of a certain flow rate and pressure to enter the capacity exchange device 201, and pushes the gas in the capacity exchange device 201 to drive the anesthesia machine to provide continuous gas for the patient. Among them, the breathing circuit 200 also includes a carbon dioxide absorption tank. When the patient exhales, the gas exhaled by the patient enters the carbon dioxide absorption tank. The carbon dioxide absorption tank can remove the carbon dioxide therein and mix it with the fresh gas containing anesthetic gas and oxygen before entering the patient's lungs, thereby completing a breathing cycle.

[0047] Among them, the capacity exchange device 201 can be a bellows assembly, and the folding bag in the bellows assembly can store a certain amount of gas containing anesthetic components when the patient inhales and exhales. Specifically, when the patient exhales, the gas exhaled by the patient enters the folding bag along the breathing tube and lifts the folding bag. When the patient inhales, the driving module 300 controls the driving gas with a certain flow rate and pressure to enter the bellows assembly, and the driving gas pushes the folding bag to move downward, thereby pressing out the gas inside the folding bag. The gas flows through the carbon dioxide absorption tank to filter out carbon dioxide, and then mixes with the fresh gas containing anesthetic gas and oxygen and enters the patient's lungs to complete a breathing cycle.

[0048] Alternatively, the capacity exchange device 201 is a capacity reflector. When the patient exhales, the gas exhaled by the patient enters the capacity reflector along the breathing tube and is stored. At the same time, the capacity reflector can discharge excess gas. When the patient inhales, the driving module 300 controls the driving gas of a certain flow rate and pressure to enter the capacity reflector and push the gas in the capacity reflector, thereby pushing out the gas inside the capacity reflector. The gas flows through the carbon dioxide absorption tank to filter out carbon dioxide, and then mixes with the fresh gas containing anesthetic gas and oxygen and enters the patient's lungs to complete a breathing 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 have in common at least that they can be used to install a breathing circuit. The difference between the two is that the second mounting platform 602 has a work surface 6021, and the work surface 6021 refers to a surface used as an operating area or an object placement area, for example, it can be used to place instruments or for doctors to take surgical records during use; the first mounting platform 601 does not have a work surface used as an operating area or an object placement area, or even if the second mounting platform 601 is provided with an area extending toward the front side of the anesthesia machine (i.e., the side facing the user), this area cannot support the installation of a drawer. A platform mounting portion is provided on the first mounting platform 601 and the second mounting platform 602, a supporting portion is provided on the fuselage column 500, the first mounting platform 601 or the second mounting platform 602 is installed on the supporting portion through the platform mounting portion, and the anesthesia machine main unit 100 is installed on the first mounting platform 601 or the second mounting platform 602; or, the supporting portion has a first mounting area and a second mounting area, the first mounting platform 601 or the second mounting platform 602 is installed on the first mounting area through the platform mounting portion, and the anesthesia machine main unit 100 is installed on the second mounting area.

[0050] refer to Figure 1 In the embodiment, that is, when the mounting platform 600 is the second mounting platform 602, the anesthesia machine mainframe 100 is mounted on the second mounting platform 602, and the second mounting platform 602 is further connected to the fuselage column 500, and the work surface 6021 is located on the side of the fuselage column 500 facing the user. The drive module is arranged in the fuselage column 500 and is installed at a lower position relative to the second mounting platform or the work surface, that is, the setting position of the drive module is not higher than the position of the second mounting platform on the fuselage column or below the work surface.

[0051] refer to Figure 2 In the embodiment, when the mounting platform 600 is the first mounting platform 601, the anesthesia machine main unit 100 and the first mounting platform 601 are both mounted on the fuselage column 500. Although the first mounting platform 601 of this embodiment has an extended area in the direction toward the front side of the anesthesia machine, the area is neither a work surface used as an operation area or an item placement area, nor can the area be used to install a drawer. The drive module is arranged in the fuselage column 500, and is arranged lower relative to the first mounting platform or the position where the breathing circuit is installed on the first mounting platform, that is, the setting position of the drive module is not higher than the position of the first mounting platform on the fuselage column or the position where the breathing circuit is installed on the first mounting platform.

[0052] Although the first mounting platform and the second mounting platform in the present application are described as being mounted on the fuselage column, the description does not limit the first mounting platform and the second mounting platform to being separate components independent of the fuselage column and the anesthesia machine main unit. The first mounting platform and the second mounting platform of the present application can be separate components separated from the fuselage column and the anesthesia machine main unit, and then mounted on the fuselage column by specific connection means when they are combined into the anesthesia machine; they can also be formed as a whole with the fuselage column, and the partial area defined on the whole is installed, and the installation at this time can be, for example, one-piece molding or non-reversible connection and fixing means; they can also be formed as a whole with the anesthesia machine main unit, and the partial area defined on the whole is installed on the fuselage column by specific connection means when they are combined into the anesthesia machine.

[0053] In an optional embodiment, a drive mounting portion 501 is provided on the fuselage column 500, and the height of the drive mounting portion 501 is lower than the height of the mounting platform 600, so that the drive module 300 can be installed on the fuselage column 500 and located at the lower part of the anesthesia machine. When the drive module 300 is arranged at the lower part of the fuselage column, the anesthesia machine can be provided with the drive module without expanding the volume of the mounting platform at the position of the mounting platform, and can also be provided with the drive module without expanding the volume of the anesthesia machine host, and the size of the anesthesia machine in the width direction can be reduced as a whole. The overall device layout of the anesthesia machine is more balanced, making the overall structure of the anesthesia machine more compact and compact. In addition, when the drive module is arranged in the installation mode of the fuselage column, whether the volume of the mounting platform of the anesthesia machine 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 portion in an integral disassembly manner, for example, the drive module may include a first bracket, each component is first arranged on the first bracket, and then the first bracket on which each component is installed is installed is installed in the fuselage column to achieve an integral installation. During disassembly, the first bracket can be disconnected from the fuselage 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 has an upper end face and a lower end face that are relatively arranged, the capacity 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 fuselage column 500, the capacity exchange device 201 faces one side (upper side) of the anesthesia machine main unit 100, and the carbon dioxide absorption tank is located on the opposite side (lower side) relative to the capacity exchange device, and the drive module 300 is installed on the fuselage column 500 at a position lower than the capacity exchange device 201.

[0055] In an optional embodiment, the work surface 6021 may be a part of the second mounting platform 602, the breathing circuit 200 is arranged on the second mounting platform 602 and is located on one side of the work surface 6021, the second mounting platform 602 is installed on the fuselage column 500, the anesthesia machine main unit 100 is installed on the second mounting platform 602 and is located above the work surface 6021, the fuselage column 500 is provided with a drive mounting portion 5011 at a position not higher than the work surface 6021, and when the drive module 300 is installed on the drive mounting portion 501, it is not higher than the position where the work surface is installed on the anesthesia machine main unit 100, which can make the arrangement, installation and removal of the drive module 300 convenient and flexible.

[0056] Exemplarily, the anesthesia machine also includes a display, which is connected to the anesthesia machine main unit 100 and is located above the mounting platform; the body column 500 is arranged below the anesthesia machine main unit 100 to support the anesthesia machine main unit 100 and the display.

[0057] In an optional embodiment, the drive module 300 includes one of the electric control drive module 301 and the pneumatic drive module 302. The electric control drive module 301 and the pneumatic drive module 302 can be interchanged on the drive mounting portion 501. The specific selection can be made according to the functional requirements of the anesthesia machine, thereby effectively realizing the interchange between the electric control drive module 301 and the pneumatic drive module 302, greatly reducing the labor intensity of the modification of the anesthesia machine main unit 100.

[0058] Among them, the anesthesia machine that uses the electric drive module 301 to control the driving gas is an electric version, and the anesthesia machine that uses the pneumatic drive module 302 to control the driving gas is a pneumatic version. Among them, the electric version and the pneumatic version of the anesthesia machine have different advantages in use, and the differences are also very large. The same model of anesthesia machine cannot be compatible with both the electric version and the pneumatic version at the same time. It either has only the electric drive module 301 or only the pneumatic drive module 302. Moreover, the electric version and the pneumatic version of the anesthesia machine have different driving methods, and the overall structural layout of the machine is also significantly different; it is impossible to make an anesthesia machine very convenient to change from an electric drive to a pneumatic drive (or vice versa).

[0059] Exemplarily, when the driving module 300 inside the anesthesia machine is an electronically controlled driving module 301, the electronically controlled driving module 301 uses a turbine to control the driving gas with a certain flow rate and pressure to enter the capacity exchange device 201, and pushes the gas inside the capacity exchange device 201. When the driving module 300 inside the anesthesia machine is a pneumatic driving module 302, the pneumatic driving module 302 uses an exhalation valve 3012 to control the driving gas with a certain flow rate and pressure to enter the capacity exchange device 201, and pushes the gas inside the capacity exchange device 201.

[0060] However, the existing pneumatic anesthesia machine and the electric anesthesia machine are distinguished by the overall structure of the machine, which results in obvious differences in the overall style of the two machines, making it impossible to flexibly switch the anesthesia machine after leaving the factory. However, the present application makes the installation of the electric control drive module 301 and the pneumatic drive module 302 compatible through the drive installation part 501, and the electric control drive module 301 and the pneumatic drive module 302 can be interchanged on the drive installation part 501. The drive installation part 501 facilitates the removal of the electric control drive module 301 and the pneumatic drive module 302 from the body column 500, thereby realizing the convenient switching between the pneumatic and electric anesthesia machines, and facilitating assembly and maintenance. At the same time, the drive installation part can unify the installation position of the electric control drive module 301 or the pneumatic drive module 302, and set the electric control drive module 301 or the pneumatic drive module 302 at a position on the fuselage column 500 that is not higher than the installation platform (or the installation position of the breathing circuit 200), that is, the electric control drive module 301 or the pneumatic drive module 302 is integrated in the lower part of the anesthesia machine, so that the anesthesia machine main unit 100 or the installation platform can be made smaller, which is helpful for the miniaturized design of the anesthesia machine.

[0061] In an optional embodiment, the anesthesia machine further includes a transfer structure 400 disposed in the fuselage column 500, the transfer structure 400 is detachably connected to the drive module 300, and is used to connect the drive module 300 and the capacity exchange device 201. Among them, the interface on the transfer structure 400 for connecting with the drive module 300 is configured to be used for connecting with both the electric control drive module 301 and the pneumatic drive module 302. The transfer structure 400 provides transfer between the capacity exchange device 201 and the drive module 300 (the pneumatic drive module 302 or the electric control drive module 301), so that a type of anesthesia machine can easily realize the interchange of the two different drive modules 300, the pneumatic drive module 302 or the electric control drive module 301, thereby reducing the economic cost caused by design changes to the anesthesia machine to adapt to different drive modules 300.

[0062] In an optional embodiment, the drive mounting portion 501 includes a receiving groove arranged in the fuselage column 500, and the structure of the receiving groove is compatible with the structure of the electric control drive module 301 and the pneumatic drive module 302, so that the electric control drive module 301 and the pneumatic drive module 302 can be respectively accommodated in the receiving groove, so that the overall structure of the electric control drive module 301 or the pneumatic drive module 302 is hidden in the fuselage column 500, which greatly reduces the size of the anesthesia machine and improves the overall aesthetics of the anesthesia machine; at the same time, it can also effectively protect the electric control drive module 301 or the pneumatic drive module 302.

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

[0064] In an optional embodiment, the electric control driving module 301 and the pneumatic driving module 302 are both provided with an inhalation channel outlet 300a, an exhalation channel inlet 300b and an exhalation channel outlet 300c, and the inhalation channel outlet 300a, the exhalation channel inlet 300b and the exhalation channel outlet 300c are located on the same side of the driving module 300 and are arranged toward the capacity exchange device 201, and are used to connect with the capacity exchange device 201. The capacity exchange device 201 can be connected with the driving module 300 through the transfer structure 400, so that the driving module 300 can control the driving gas of a certain flow rate and pressure to enter the capacity exchange device 201, and push the gas in the capacity exchange device 201 to provide gas output for the patient.

[0065] Among them, the inhalation channel outlet 300a, the exhalation channel inlet 300b and the exhalation channel outlet 300c are arranged on the same side, which can facilitate the connection of the inhalation channel outlet 300a, the exhalation channel inlet 300b and the exhalation channel outlet 300c with the capacity exchange device 201, such as connecting the inhalation channel outlet 300a, the exhalation channel inlet 300b and the exhalation channel outlet 300c with the capacity exchange device 201 accordingly through a loop pipeline, or connecting the inhalation channel outlet 300a, the exhalation channel inlet 300b and the exhalation channel outlet 300c with the capacity exchange device 201 through a component similar to the transfer structure 400, or the transfer structure 400 and the inhalation channel outlet 300a, the exhalation channel inlet 300b and the exhalation channel outlet 300c are integrally formed, and then the capacity exchange device 201 is connected to the inhalation channel outlet 300a, the exhalation channel inlet 300b and the exhalation channel outlet 300c.

[0066] Since both the electric-controlled drive module 301 and the pneumatic drive module 302 are provided with an inhalation channel outlet 300a, an exhalation channel inlet 300b and an exhalation channel outlet 300c, and the inhalation channel outlet 300a, the exhalation channel inlet 300b and the exhalation channel outlet 300c are located on the same side and are arranged toward the capacity exchange device 201, an anesthesia machine of one model can easily realize the interchange of two different drive modules 300, namely the electric-controlled drive module 301 or the pneumatic drive module 302, thereby reducing the economic cost caused by design changes to the anesthesia machine to adapt to different drive modules 300. For example, the electric-controlled drive module 301 is connected to the capacity exchange device 201 on the breathing circuit 200 through the inhalation channel outlet 300a, the exhalation channel inlet 300b and the exhalation channel outlet 300c. When it is necessary to replace the electric-controlled drive module 301 with the pneumatic drive module 302, the pneumatic drive module 302 can be directly replaced to the anesthesia machine. Similarly, the pneumatic drive module 302 can be connected to the capacity exchange device 201 on the breathing circuit 200 through the inhalation channel outlet 300a, the exhalation channel inlet 300b and the exhalation channel outlet 300c, thereby solving the problem that the structural layout of an anesthesia machine cannot support the interchange of two drive modules 300.

[0067] In an optional embodiment, if Fig. 9 and Fig.10 As shown, the transfer structure 400 includes a driving gas inlet 400a, an exhalation valve inlet 400b and an exhalation valve outlet 400c, wherein 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 operation.

[0068] In an optional embodiment, the driving gas 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 arranged toward the driving module 300 so as to be connected to the driving module 300.

[0069] In an optional embodiment, an exhalation inlet 4021 and a driving gas outlet 4022 are further provided on the transit structure 400, and the exhalation inlet 4021 and the driving gas outlet 4022 are located on the same side of the transit structure 400 and are arranged toward one side of the capacity exchange device 201, and are used to be connected to the capacity exchange device 201, so that the capacity exchange device 201 can be connected to the driving module 300 through the transit structure 400, so that the driving module 300 can control the driving gas of a certain flow rate and pressure to enter the capacity exchange device 201, and push the gas in the capacity 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 interface 4023 on the same side as the exhalation inlet 4021 or the driving gas outlet 4022, which is used to connect to the APL valve in the anesthesia machine, so that the gas exhausted by the APL valve can be discharged from the APL exhaust interface 4023, thereby controlling the gas pressure of the respiratory system in the anesthesia machine so that the patient's inhalation gas pressure can be adjusted through the APL valve.
