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 this application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0038] 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.

[0039] like Figures 1 to 6As shown, the present application provides an anesthesia machine, including a main frame 100, a circuit assembly 200 and an interface assembly 300. The interface assembly 300 is arranged on the main frame 100, the main frame 100 is provided with a receiving cavity 101, and the circuit assembly 200 is arranged in the receiving cavity 101 and connected to the main frame 100.

[0040] In this embodiment, the interface component 300 includes a bag interface 301 connected to the air circuit of the loop component 200. The bag interface 301 is connected to the main frame 100 and is independently arranged relative to the loop component 200. The bag interface 301 is used to connect to the breathing bag so that the patient's exhaled gas can enter the breathing bag, and then by pressing the breathing bag, the breathing bag can drive the exhaled gas into the carbon dioxide absorption tank 400 of the anesthesia machine, and then the gas coming out of the carbon dioxide absorption tank 400 is delivered to the patient through the air circuit pipeline and mixed with fresh gas containing anesthetics, and this cycle is repeated.

[0041] After adopting the above technical solution, since the bag interface 301 is separated from the loop assembly 200 and is independently arranged relative to the loop assembly 200, the bag interface 301 can be arranged at different positions of the main frame 100, and does not need to be limited by the installation position of the loop assembly 200, so that the breathing bag connected to the bag interface 301 can be prevented from being squeezed or deformed due to the installation position of the bag interface 301, so that the breathing bag can be fully stretched, and there will be no problems such as rupture, air path blockage and increased air resistance due to squeezing or deformation of the breathing bag, and there will be no leakage of anesthetic from the rupture of the breathing bag, thereby affecting patients, staff and the environment. In addition, the anesthesia machine of the present application can also be adapted to the use of multiple scenarios, and the breathing bag will not be limited by the position of the bag interface 301; at the same time, the air path pipeline connecting the bag interface 301 and the loop assembly 200 can also be stored in the main frame 100, making the overall shape and volume of the anesthesia machine more compact.

[0042] In an optional embodiment, if Figures 1 to 4 As shown, the bag interface 301 is arranged near the upper part of the main frame 100, which not only ensures the normal function of the bag interface 301, but also solves the risk of using breathing bags of different sizes when the anesthesia machine is placed on the desktop. The breathing bag will not be squeezed or even deformed due to the large size of the breathing bag, which may easily cause rupture, airway blockage and increased air resistance. There is a risk of suffocation for surgical patients, and it may also cause harm to the environment and staff due to anesthetic leakage.

[0043] In an optional embodiment, the bag interface 301 is located above the loop assembly 200, which not only ensures the normal function of the bag interface 301, but also solves the risk of using breathing bags of different sizes on the anesthesia machine when working on the desktop. The larger size of the breathing bag will not be limited by the loop assembly 200, which may cause the breathing bag to be squeezed or even deformed, and then easily cause problems such as rupture, airway blockage and increased air resistance, which may pose a risk of suffocation to surgical patients and may also cause harm to the environment and staff due to anesthetic leakage.

[0044] After adopting the above scheme, since the bag interface 301 is arranged close to the upper part of the main frame 100 or is located above the loop assembly 200, the internal air circuit of the loop assembly 200 can be simplified to a certain extent, thereby reducing the structural limitations of the loop assembly 200 caused by the internal air circuit design; at the same time, since the bag interface 301 is located at a higher position, it has no effect on all application scenarios of the anesthesia machine, such as desktop, trolley version, transportation and wall-mounted application scenarios, and can avoid some risks caused by insufficient space for the breathing bag when the anesthesia machine is placed on the desktop; secondly, when replacing the bag interface 301, there is no need to disassemble the loop assembly 200, reducing the accidental failure of the internal air circuit of the loop assembly 200 during disassembly and assembly, and the maintainability is strong.

[0045] In an optional embodiment, the circuit assembly 200 further includes a pressure relief valve 700, and the pressure relief valve 700 and the bag interface 301 are both located on the same side of the main frame 100, so as to facilitate the operation of the pressure relief valve 700 and the breathing bag connected to the bag interface 301, effectively ensuring the precise control of the anesthesia machine, so that the gas from the carbon dioxide absorption tank 400 can be fully mixed with the fresh gas containing anesthetics, and at the same time ensuring that the air pressure in the circuit assembly 200 will not cause harm to the patient. Among them, the main function of the breathing bag is to assist or control breathing, and the pressure relief valve 700 is used to adjust the pressure of the patient's inhaled gas.

[0046] Exemplarily, the pressure relief valve 700 includes but is not limited to an APL valve, which is arranged on the circuit assembly 200 and is used to adjust the upper pressure limit of the breathing circuit of the anesthesia machine. When the anesthesia machine is in a manual state, the airflow of the patient's inhalation, through the manual hand pinching of the breathing bag, the fresh gas in the breathing bag enters the patient's respiratory tract through the inhalation valve of the anesthesia machine, etc. At this time, the APL valve can be used to adjust the airflow pressure of the breathing circuit in the manual state. The airflow of the patient's exhalation, the carbon dioxide gas exhaled by the patient enters the carbon dioxide absorption tank 400 of the anesthesia machine, and reacts with the carbon dioxide absorbent in the carbon dioxide absorption tank 400, the carbon dioxide gas is absorbed, and the remaining gas returns to the breathing circuit. Among them, the pressure relief valve 700 and the bag interface 301 are located on the same side of the main frame 100, and when the medical staff operates, the medical staff can face the breathing bag and the APL valve, and operate with two hands synchronously, one hand presses the breathing bag, and the other hand presses the APL valve synchronously, and when the breathing bag is released, the APL valve is released, and the eyes of the medical staff can be used to observe the patient, and the patient includes but is not limited to animals or human bodies.

[0047] In an optional embodiment, the main frame 100 is provided with an interface mounting portion connected to the loop assembly 200, and the leather bag interface 301 is detachably connected to the interface mounting portion. The installation is flexible and the disassembly is convenient. It can be used according to specific circumstances and is convenient for inspection and maintenance. It has strong environmental adaptability, especially for installation in a relatively small space.

[0048] In an optional embodiment, the bag interface 301 is rotatably installed in the interface mounting portion, and different installation angles can be selected according to specific application scenarios. At the same time, the rotation angle of the bag interface 301 can also be adjusted axially along the interface mounting portion to avoid the breathing bag being limited by the installation position. It is designed to solve the risk of rupture of the breathing bag due to squeezing, and has a simple structure, firm fixation, and easy disassembly and assembly.

[0049] In an optional embodiment, a first disassembly part is provided on the interface mounting portion, and a second disassembly part is provided on the skin bag interface 301. The skin bag interface 301 is installed on the main frame 100 through the cooperation of the first disassembly part and the second disassembly part. It is not only simple and convenient to operate, but also safe and reliable in connection.

[0050] In an optional embodiment, if Figure 5 and Figure 6 As shown, the first disassembly part includes a bayonet structure arranged on the interface mounting part, and the second disassembly part includes a snap structure 3014 arranged on the skin bag interface 301. The snap structure 3014 is snapped into the bayonet structure, making the installation of the skin bag interface 301 more convenient and labor-saving, effectively improving the efficiency and convenience of the installation of the skin bag interface 301, and having strong maintainability.

[0051] In an optional embodiment, the first disassembly part includes a connecting hole arranged on the interface mounting portion, and the second disassembly part includes a fixing hole 3015 arranged on the leather bag interface 301. The number and positions of the connecting holes correspond to the number and positions of the fixing holes 3015, so that the fixing parts 102 such as screws can pass through the connecting holes and be fixed in the fixing holes 3015. Not only is the structure simple, but the fixing is also firm and convenient for assembly and disassembly.

[0052] In an optional embodiment, the first disassembly part includes a plurality of bayonet structures, and the second disassembly part includes a bayonet structure 3014 matching the number of the bayonet structures. The plurality of bayonet structures are arranged around the peripheral side of the interface mounting part. After the bayonet structure 3014 is installed to the bayonet structure, the bayonet structure 3014 can be snapped into the interface mounting part by rotation. The structure is simple, the fixation is firm, and the disassembly and assembly are convenient.

[0053] Exemplarily, the first disassembly member includes a bayonet structure and a connection hole, and the second disassembly member includes a buckle structure 3014 and a fixing hole 3015. When the skin bag interface 301 needs to be installed on the interface installation part, the skin bag interface 301 is first inserted into the interface installation part through the cooperation of the buckle structure 3014 and the bayonet structure, and then the skin bag interface 301 is rotated clockwise or counterclockwise to a certain angle so that the skin bag interface 301 can be completely engaged in the interface installation part, and finally the fixing member 102 passes through the connection hole and is connected to the fixing hole 3015, so that the skin bag interface 301 is firmly fixed on the main frame 100. The angle of the clockwise or counterclockwise rotation of the skin bag interface 301 relative to the main frame 100 can be, but is not limited to, 45 degrees.

[0054] In an optional embodiment, the bag interface 301 includes a first pipe portion 3011 for connecting to a breathing bag and a second pipe portion 3012 for being installed to an interface mounting portion. The center line of the first pipe portion 3011 and the center line of the second pipe portion 3012 are arranged at a first angle. This not only meets the structural strength of the bag interface 301, but also ensures that the connection between the breathing bag and the bag interface 301 is not obstructed, and even does not cause the breathing bag to be damaged due to folding.

[0055] In an optional embodiment, the first angle ranges from 100 degrees to 110 degrees, which not only meets the structural strength of the bag interface 301, but also ensures that the connection between the breathing bag and the bag interface 301 is not hindered, and even does not cause the breathing bag to be damaged due to folding.

[0056] In an optional embodiment, the length of the second pipe portion 3012 extending from the main frame 100 is greater than or equal to 20 mm, which is beneficial for medical personnel to plug and unplug the breathing bag on the bag plug-in and unplug-out interface 301.

[0057] Exemplarily, the skin bag interface 301 includes a blocking portion 3013, which is arranged on the second pipe portion 3012 and is used to block the length of the second pipe portion 3012 extending into the interface installation portion. The blocking portion 3013 divides the second pipe portion 3012 into a first section and a second section, the first section extends toward one side of the first pipe portion 3011, the first pipe portion 3011 is connected to the end of the first section away from the blocking portion 3013, and the second section extends in a direction away from the first pipe portion 3011. The buckle structure 3014 and the fixing hole 3015 are arranged in the second section and can be plugged into the interface installation portion with the second section.

[0058] In an optional embodiment, at least two bosses are provided on the second section, the axes of the at least two bosses are perpendicular to the center line of the second pipe portion 3012, the fixing holes 3015 are provided on the at least two bosses, and there is a first preset distance between the snap structure 3014 and the blocking portion 3013, and the value of the first preset distance is adapted to the wall thickness of the main frame 100.

[0059] In an optional embodiment, the interface assembly 300 further includes an oxygen interface 303, which is disposed on the side of the main frame 100 and is used to connect to a high-pressure gas source, an oxygen generator or an oxygen supply tank, etc., so as to supply oxygen to the anesthesia machine, which is not limited in the present application.

[0060] It should be noted that the main frame 100 has a front, a side and a back, the front is facing the side operated by medical staff, the back is the side opposite to the front, and the side is connected between the front and the back, that is, the two sides of the main frame 100. Among them, the accommodating chamber 101 is arranged on the front, and the back can be used in the wall version for but not limited to mounting the main frame 100 on the wall. The present application sets the oxygen interface 303 on the side of the main frame 100, which can adapt to different installation scenarios, such as the wall version. Since the distance between the back of the main frame 100 and the wall is relatively small, it is not convenient to insert the tube. Therefore, the oxygen interface 303 of the present application can facilitate the pipe plugging of the main frame 100 in any installation scenario. Among them, the oxygen interface 303 can be on one of the two sides of the main frame 100, which is not limited by the present application. In an optional embodiment, the interface assembly 300 also includes an exhaust gas interface 302, which is arranged on the side of the main frame 100 for connecting a sewage system, such as an exhaust gas absorption tank, a sewage pipe and an active AGSS, etc., which is not limited by the present application.

[0061] After adopting the above technical solution, since the exhaust gas interface 302 is set on the side of the main frame 100, it can adapt to different installation scenarios, such as the wall-mounted version. Since the distance between the back of the main frame 100 and the wall is relatively small, it is not convenient to insert the pipe. Therefore, the exhaust gas interface 302 of the present application can facilitate the pipe insertion of the main frame 100 in any installation scenario. Among them, the exhaust gas interface 302 can be on one of the two sides of the main frame 100, and this application is not limited.

[0062] In an optional embodiment, the interface assembly 300 further includes an air interface 304, which is disposed on a side of the main frame 100 and is used to connect a high-pressure gas source, an oxygen generator or an oxygen supply tank, etc., so as to supply oxygen to the anesthesia machine, which is not limited in the present application.

[0063] After adopting the above technical solution, since the air interface 304 is set on the side of the host frame 100, it can adapt to different installation scenarios, such as the wall-mounted version. Since the distance between the back of the host frame 100 and the wall is relatively small, it is not convenient to insert the pipe. Therefore, the air interface 304 of the present application can facilitate the pipe insertion of the host frame 100 in any installation scenario. Among them, the air interface 304 can be on one of the two sides of the host frame 100, and the present application does not limit it.

[0064] Exemplarily, the exhaust gas interface 302 and the bag interface 301 are arranged on one side of the main frame 100, and the oxygen interface 303 and the air interface 304 are arranged on the other side of the main frame 100, thereby reducing the distance between the back side of the main frame 100 and the wall, which can not only adapt to the wall-mounted version of the anesthesia machine, but also facilitate the connection of pipelines.

[0065] In an optional embodiment, if Figure 3 and Figure 4 As shown, the anesthesia machine also includes a storage device 902, which is arranged on the back side of the main frame 100. The storage device 902 is on the side facing away from the accommodating cavity 101 and forms a storage space. The storage space is used to store the cables and / or trachea of ​​the anesthesia machine, so that the cables and / or trachea of ​​the anesthesia machine can be arranged neatly and orderly on the main frame 100, avoiding multiple cables and / or trachea from being entangled with each other and tied into a ball, thereby facilitating the use of medical staff and also improving the appearance of the anesthesia machine.

[0066] In an optional embodiment, if Figure 2 and Figure 3As shown, the anesthesia machine further includes a pressure gauge 600, which is arranged on the same side of the main frame 100 as the bag interface 301, and can be used to monitor the expiratory pressure and / or inspiratory pressure in the breathing circuit of the anesthesia machine. After adopting the above technical solution, since the pressure gauge 600 and the bag interface 301 are arranged on the same side of the main frame 100, it is convenient for medical personnel to observe the pressure gauge 600 while operating the breathing bag connected to the bag interface 301. When the pressure of the rapidly supplied oxygen is too high, the APL valve automatically opens and discharges excess gas.

[0067] Exemplarily, the gas in the breathing bag enters the patient's respiratory tract through manual squeezing, and the pressure gauge 600 is used to monitor the patient's respiratory pressure, which can monitor the expiratory pressure and inspiratory pressure in the breathing circuit of the anesthesia machine. When the manual pressure or the rapid supply of oxygen pressure value is greater than the set value of the APL valve, the APL valve automatically opens and removes excess gas. In this embodiment, the left and right hands of the medical staff are used to operate the APL valve and the breathing bag respectively. The eyes not only need to observe the patient's condition, but also occasionally observe the value of the pressure gauge 600; therefore, the present application sets the pressure gauge 600, the APL valve and the bag interface 301 on the same side of the main frame 100, which can facilitate the operation and observation of the medical staff. It should be noted that the APL valve and the air bag interface can be set on the same side or in a close position, and the pressure gauge 600 can be set in a position that is easy to observe, and the present application does not limit it.

[0068] In an optional embodiment, the pressure gauge 600 is disposed above the circuit assembly 200 and is spaced apart from the pressure relief valve 700 disposed on the circuit assembly 200 to facilitate operation and observation by medical personnel.

[0069] In an optional embodiment, the anesthesia machine also includes a flow meter 800, which is disposed in the middle of the accommodating chamber 101 and extends along the height direction of the accommodating chamber 101, and is used to separate the accommodating chamber 101 into a first chamber 1011 and a second chamber 1012. The circuit assembly 200 is disposed in the first chamber 1011, and the anesthetic vaporizer 500 is disposed in the second chamber 1012, and is used to convert liquid anesthetic into anesthetic gas, and then mix it with the gas from the interface assembly 300 and deliver it to the patient.

[0070] Exemplarily, the anesthesia machine further includes a carbon dioxide absorption tank 400, which is connected to the circuit assembly 200 and disposed in the first chamber 1011, and is used to absorb carbon dioxide in the patient's exhaled gas to ensure the freshness of the inhaled air flow.

[0071] In an optional embodiment, if Figure 3 and Figure 4As shown, a frame fixing member 901 is provided on one side of the main frame 100 facing away from the accommodating chamber 101, and the frame fixing member 901 is used to be detachably connected to a fixing bracket fixed on the wall to fix the anesthesia machine on the wall. The frame fixing member 901 includes but is not limited to a wall screw, and the wall screw can be detachably connected to the fixing bracket, and the fixing bracket is fixed on the wall.

[0072] In an optional embodiment, a support portion 900 is provided at the bottom of the main frame 100 for supporting the anesthesia machine when it is placed, wherein the support portion 900 includes but is not limited to a foot pad, which can facilitate the placement of the anesthesia machine on the desktop.
