[0001] This invention relates to the field of medical device technology, and in particular to an anesthesia machine. Background Technology

[0002] Anesthesia machines are among the most commonly used pieces of equipment in operating rooms. High-end anesthesia machines typically use oxygen cells to measure the oxygen concentration of the mixed gas, allowing doctors to more precisely control the oxygen supply during surgery. Currently, the oxygen cells on anesthesia machines are exposed, making them susceptible to dust accumulation or entry into the machine through the interface between the oxygen cell and the breathing circuit, which is inconvenient for cleaning. Furthermore, exposed oxygen cells also affect the machine's appearance. Summary of the Invention

[0003] In view of this, embodiments of the present invention provide an anesthesia machine that can conceal the oxygen cell, avoid the oxygen cell being exposed and affecting the aesthetics of the anesthesia machine, prevent dust from settling on the oxygen cell, and prevent dust from entering the interior of the anesthesia machine through the interface between the oxygen cell and the breathing circuit.

[0004] This invention provides an anesthesia machine, including an anesthesia machine body, a breathing circuit, and an oxygen battery housing structure for installing an oxygen battery. When the oxygen battery is installed in the oxygen battery housing structure, the detection end of the oxygen battery is connected to the breathing circuit to detect the oxygen content of the breathing circuit. The oxygen battery housing structure is installed on the anesthesia machine body and includes a housing compartment and a door cover.

[0005] The containment chamber is a hollow structure with an opening. The door cover is connected to the opening of the containment chamber in an openable and closable manner. When the door cover is closed, the containment chamber is sealed. When the door cover is opened, the containment chamber is opened.

[0006] In this invention, when the door is closed, the door seals the opening of the receiving chamber, so that the door and the receiving chamber form a closed cavity, which can hide the oxygen battery and prevent the oxygen battery from being exposed and affecting the appearance of the anesthesia machine. At the same time, it also prevents dust from entering the anesthesia machine through the interface between the oxygen battery and the breathing circuit. Attached Figure Description

[0020] The following will refer to the appendices in the embodiments of the present invention. Figure 1-10 The technical solutions in the embodiments of the present invention will be clearly and completely described. The present invention can be implemented in many different forms and is not limited to the implementation methods described in this embodiment. The purpose of providing the following specific embodiments is to facilitate a clearer and more thorough understanding of the disclosure of the present invention. The terms indicating directions such as up, down, left, and right are only used to refer to the position of the structure shown in the corresponding drawings.

[0021] It is understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. When used herein, the singular forms “a” and “” are intended to include the plural forms as well, unless the context clearly indicates otherwise. Furthermore, when used in this specification, the terms “comprising” and / or “including” indicate the presence of features, integrals, steps, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, elements, components, and / or combinations thereof. The following description is a preferred embodiment for carrying out the invention; however, the description is for the purpose of illustrating the general principles of the invention and is not intended to limit the scope of the invention. The scope of protection of this invention is determined by the appended claims.

[0022] Please refer to the following: Figure 1 and Figure 2 This is a schematic diagram of an anesthesia machine 1000 provided in an embodiment of the present invention. The anesthesia machine 1000 may include an anesthesia machine body 100, a display screen 500 disposed on the anesthesia machine body 100, and a breathing circuit 300 and an oxygen battery housing structure 400 for mounting an oxygen battery 350 disposed below the workbench 400 of the anesthesia machine body 100. This arrangement allows the workbench 400 to conceal the breathing circuit 300 and the oxygen battery housing structure 400, thus improving the appearance. When the oxygen battery... Figure 1 After being installed in the oxygen cell housing structure 400 as shown, the detection end of the oxygen cell 350 is connected to the breathing circuit 300, thereby enabling the detection of the oxygen content within the breathing circuit 300. The anesthesia machine body 100 is mounted on the cabinet 600, which is mounted on the base 700. Casters 710 are installed at the bottom of the base 700 to facilitate the movement of the anesthesia machine 1000.

[0023] Please refer to the following: Figure 3 The oxygen cell housing structure 300 includes a housing compartment 310 and a door cover 320, and is mounted on the anesthesia machine body 100. Specifically, Figure 1 The diagram shows the state of the oxygen cell housing structure 300 when the door cover 320 is open. Figure 2The diagram shows the oxygen cell housing structure 300 with its cover 320 closed. Since the oxygen cell housing structure 300 is mounted on the anesthesia machine body 100, when the cover 320 is closed, the oxygen cell 350 is concealed, preventing it from being exposed and affecting the aesthetics of the anesthesia machine 1000. It also prevents dust from entering the anesthesia machine 1000 through the interface between the oxygen cell 350 and the breathing circuit 200. It should be noted that in the embodiments disclosed in this invention, the oxygen cell housing structure 300 is a separate component, detachably connected to the anesthesia machine body 100. Specifically, the oxygen cell housing structure 300 and the anesthesia machine body 100 can be connected by screws or by snap-fit. This facilitates replacement of the oxygen cell housing structure 300 when it is damaged. In some other embodiments, the oxygen cell housing structure 300 can be integrally formed with the anesthesia machine body 100.

[0024] In this embodiment of the invention, the oxygen cell housing structure 300 is located below the cover plate 312 on the left side of the workbench 400 of the anesthesia machine body 100. This facilitates connection with the breathing circuit 200, which is also located below the cover plate 312, and avoids interference between the oxygen cell housing structure 300 and other components of the anesthesia machine 1000. It is easy to operate and has a beautiful appearance and compact structure.

[0025] like Figure 3 As shown, the oxygen cell housing structure 300 includes a housing chamber 310 and a door cover 320. The housing chamber 310 is a hollow structure with an opening. The door cover 320 is closable and connectable to the opening of the housing chamber 310. When the door cover 320 is closed, the housing chamber 310 is sealed, housing the oxygen cell 350 inside. When the door cover 320 is opened, the housing chamber 310 is opened, facilitating the installation of the oxygen cell 350 within the oxygen cell housing structure 300, allowing the detection end of the oxygen cell 350 to connect to the breathing circuit 200. The oxygen cell housing structure 300 of this embodiment prevents dust from falling onto the oxygen cell 350 and prevents dust from entering the anesthesia machine 1000 through the interface between the oxygen cell 350 and the breathing circuit 200. Furthermore, the oxygen cell housing structure 300 can conceal the oxygen cell 350, improving the overall appearance of the anesthesia machine 1000 compared to an exposed installation method.

[0026] In some of these embodiments, see Figure 3 and Figure 4 The door cover 320 is hinged to the receiving chamber 310 to facilitate the opening and closing of the door cover 320. The door cover 320 has a connecting hole 313 for mounting a rotating shaft 323. The rotating shaft 323 is fixed on the door cover 320, and both ends of the rotating shaft 323 are rotatably mounted on the receiving chamber 310.

[0027] In some other embodiments, the cover 320 can be detachably fastened to the opening of the receiving compartment 310, or the cover 320 can be pulled out and installed at the opening of the receiving compartment 310, i.e., the cover 320 is a pull-out door. When the cover 320 is a pull-out door, the sliding direction of the cover 320 is perpendicular to the axis of the receiving compartment 310 and parallel to the end face where the outlet of the receiving compartment 310 is located. The receiving compartment 310 is opened and closed by pushing and pulling the cover 320. It should be noted that the sliding direction of the cover 320 can also be set to be parallel to the axis of the receiving compartment 310 and perpendicular to the end face where the outlet of the receiving compartment 310 is located, similar to a drawer-type structure. To facilitate the sliding of the cover 320, a handle can be provided on the cover 320. The handle can be L-shaped, arc-shaped, or circular, etc. To prevent slippage when pulling the handle, an anti-slip layer is pasted or etched on the handle.

[0028] In some embodiments, such as Figure 4 As shown, the door cover 320 includes a door body portion 321 and a door connecting portion 322, wherein the door body portion 321 is connected to the door connecting portion 322. Specifically, the door body portion 321 and the door connecting portion 322 are integrally formed and connected. In some other embodiments, the door body portion 321 and the door connecting portion 322 can also be detachably connected, for example, by screw connection or snap-fit ​​connection.

[0029] Specifically, a pivot 323 is installed on the side of the door connecting part 322 that faces away from the door body part 321, such as Figure 4 As shown, the pivot 323 is rotatably mounted on the end of the receiving compartment 310, the door body 321 is used to cover the opening, and both ends of the pivot 323 are mounted on the receiving compartment 310 via bearings. In some other embodiments, the door connecting part 322 and the receiving compartment 310 can be connected by hinges, etc.

[0030] In some embodiments, such as Figure 4 As shown, the cross-section of the door body 321 is square. In some other embodiments, the cross-section of the door body 321 is circular or irregular.

[0031] In some embodiments, see Figure 3 and Figure 4The oxygen cell housing structure 300 also includes a locking device 330. When the door cover 320 is closed, the locking device 330 locks the door cover 320 and the housing compartment 310 to prevent the door cover 320 from shaking due to vibration during the operation of the anesthesia machine 1000. The locking device 330 can be any device capable of locking the door cover 320. Specifically, in the oxygen cell housing structure 300 described above, the opening and closing of the door cover 320 is controlled by pressing the independently provided locking device 330. In some other embodiments, the locking device 330 can also be a latch lock or a bolt, etc. In some other implementations, a separate locking device 330 may not be provided, and a push-type door lock structure may be used, in which the housing compartment 310 is opened and closed by directly pressing the door cover 320.

[0032] Specifically, the present invention discloses a locking device 330 including a lock base 331 and a lock latch 332, one of which is mounted on a door cover 320, and the other of which is mounted on a receiving compartment 310. In one embodiment, as shown... Figure 5 As shown, the lock base 331 is mounted on the receiving compartment 310, and the latch 332 is mounted on the door cover 320. It should be understood that in some other embodiments, the latch 332 may also be integrally formed with the door cover 320.

[0033] In some embodiments, the lock base 331 includes a connecting portion 331a and a locking portion 331b. One end of the connecting portion 331a is fixed to the inner wall of the receiving chamber 310, and the latch 332 is mounted on the door cover 320. The other end of the connecting portion 331a is connected to the locking portion 331b. A slot is formed on the end face where the outlet of the receiving chamber 310 is located, and the locking portion 331b extends into the slot to form a locking position that can lock the latch 332. When the door cover 320 is locked on the receiving chamber 310, the latch 332 is engaged in the locking position formed by the locking portion 331b and the slot. When the door cover 320 needs to be opened, the locking portion 331b is moved to increase the gap between the locking portion 331b and the slot, thereby opening the latch 332.

[0034] To facilitate the opening of the door cover 320, the present invention discloses that the locking device 330 further includes an unlocking component 340, such as... Figure 5 and 6As shown, the unlocking component 340 is installed on the side wall of the receiving compartment 310, and the driving end of the unlocking component 340 can push or pull the connecting part 331a, causing the connecting part 331a to rotate away from the slot, releasing the latch 332, thereby unlocking. The unlocking component 340 includes a button sleeve 341 and a door cover button 342. The button sleeve 341 is installed on the side wall of the receiving compartment 310, and the door cover button 342 is slidably installed in the button sleeve 341 to drive the connecting part 331a. The driving end of the door cover button 342 that drives the connecting part 331a and the latching part 331b are both located on the same side of the connection point between the connecting part 331a and the receiving compartment 310. By pressing the door cover button 342, the connecting part 331a can be pushed to rotate away from the slot, thereby causing the latching part 331b to move away from the slot, thereby releasing the latch 332.

[0035] To facilitate the reset of the door cover button 342, this invention discloses that the door cover button 342 is provided with a pull cord or pull ring, and the door cover button 342 is reset by pulling the pull cord or pull ring. The material of the pull cord and pull ring is not limited, as long as it can reset the door cover button 342, it is within the protection scope of this invention.

[0036] To reduce manual labor intensity, the present invention discloses that the unlocking component 340 further includes an elastic reset member 343. The elastic reset member 343 is placed inside the button sleeve 341, and its two ends act on the button sleeve 341 and the door cover button 342 respectively, for resetting the door cover button 342. When the door cover button 342 is pressed, the elastic reset member 343 can automatically drive the door cover button 342 to return to its original position, avoiding the need to manually pull the door cover button 342 to reset.

[0037] Specifically, the present invention discloses that the elastic reset member 343 is a compression spring. In some other embodiments, in order to further reduce the intensity of manual labor, a drive telescopic device can be provided instead of the elastic reset member 343. The drive telescopic device drives the door cover button 342 to extend and retract. Specifically, the drive telescopic device can be a cylinder or a hydraulic cylinder, etc.

[0038] In some embodiments, such as Figure 5 and Figure 6As shown, the end face of the receiving compartment 310 with an opening is provided with a raised edge 324 surrounding the opening. When the door cover 320 is closed, the door cover 320 is recessed or flush with the raised edge 324 to prevent the door cover 320 from protruding from the receiving compartment 310 and to improve the appearance. The receiving compartment 310 includes a compartment body 311 and a cover plate 312. The cover plate 312 is detachably connected to the compartment body 311 by screws. In some other embodiments, the cover plate 312 and the compartment body 311 can also be snap-fitted or hinged. When one end of the cover plate 312 is hinged to the compartment body 311, the other end of the cover plate 312 is snap-fitted onto the compartment body 311. To facilitate the opening and closing of the cover plate 312, a handle for easy holding can be provided on the cover plate 312. The shape of the handle is not limited.

[0039] The inner cavity of the receiving chamber 310 is formed by the chamber body 311 and the cover plate 312. Specifically, the cover plate 312 is the left cover plate 312 on the workbench. In some other embodiments, the cover plate 312 may also be a separate cover plate 312. A connecting hole 313 for mounting screws is provided on the end face of the chamber body 311. The screws are countersunk screws, and a silicone plug 314 is fixed to the top of the connecting hole 313 to cover the screws. In some other embodiments, other blocks or other devices that can cover the screws may be used instead of the silicone plug 314.

[0040] In some embodiments, such as Figures 5-7 As shown, the oxygen cell 350 is mounted on the oxygen cell mounting base 360. A positioning mounting hole 210 is provided on the breathing circuit 200. After the oxygen cell mounting base 360 ​​passes through the receiving chamber 310, its end is threadedly connected to the positioning mounting hole 210, facilitating the positioning and installation of the oxygen cell receiving structure 300. The oxygen cell mounting base 360 ​​has a mounting position for the oxygen cell 350. A limiting protrusion for the oxygen cell 350 is provided at the outlet end of the mounting position. To facilitate the engagement or disengagement of the oxygen cell 350 from the limiting protrusion, a handle 361 is provided on the limiting protrusion. The handle 361 is strip-shaped. Under normal conditions, the limiting protrusion is in a state where it can engage the oxygen cell 350. When it is necessary to release the oxygen cell 350, the handle is pulled away from the axis of the oxygen cell mounting base 360 ​​to disengage the oxygen cell 350 from the limiting protrusion.

[0041] like Figure 7As shown, the oxygen battery cable 370 is positioned behind the door cover 320. When the door cover 320 is closed, it presses the end of the oxygen battery cable 370 against the oxygen battery 350, thus achieving an electrical connection between the two. This avoids the need for additional interconnection structures on the ends of the oxygen battery cable 370 and the oxygen battery 350, resulting in a simpler structure. A gap is provided between the door connection 322 and the receiving compartment 310, through which the oxygen battery cable 370 extends into the anesthesia machine body 100. This prevents the oxygen battery cable 370 from being exposed and affecting the aesthetics of the anesthesia machine 1000, and also prevents dust from settling on the oxygen battery cable 370.

[0042] In some embodiments, the door cover button 342 includes a button cover 342a and a button lever 342b, such as Figure 8 As shown, the button cover 342a is fixed to one end of the button rod 342b, and the other end of the button rod 342b is the driving end of the unlocking assembly 340. A compression spring is sleeved on the button rod 342b, and both ends of the compression spring abut against either the button cover 342a or the button sleeve 341. In some other embodiments, one of the button cover 342a and the button sleeve 341 is connected to one end of the compression spring, and the other abuts against the other end of the compression spring. That is, it is necessary to ensure that one end of the compression spring is movable.

[0043] In some embodiments, a limiting portion 344 is provided on the button cover 342a or the button lever 342b, such as... Figure 8 As shown, when the compression spring is in its initial state, the limiting part 344 engages with the button sleeve 341. When the button cover 342a is pressed to compress the compression spring, the limiting part 344 separates from the button sleeve 341. The limiting part 344 prevents the button cover 342a from slipping off the button sleeve 341. Specifically, the present invention discloses that the limiting part 344 is disposed on the button cover 342a, and the limiting part 344 is a hook that extends out of the button sleeve 341 and engages with the bottom wall of the button sleeve 341. Specifically, there are multiple hooks, evenly distributed in the circumferential direction of the button cover 342a, so as to achieve a uniform distribution of the force applied by the button cover 342a to the button sleeve 341.

[0044] In other embodiments, the limiting part 344 can also be other structures. For example, the limiting part 344 is disposed on the button cover 342a, and the limiting part 344 is a guide block. A sliding groove is formed on the inner wall of the button sleeve 341, and the end of the sliding groove away from the connecting part 331a is a closed end. The guide block slides in the sliding groove to prevent the guide block from slipping off. The limiting part 344 can also be a retaining spring. The retaining spring is engaged with the part of the button rod 342b that extends out of the button sleeve 341. When the spring is compressed in the initial state, the retaining spring is engaged with the outer bottom wall of the button sleeve 341 to prevent the button cover 342a from falling off the button sleeve 341. Alternatively, a gasket can be used. The gasket is fixed to the bottom end of the button rod 342b by screws. The gasket is located outside the button sleeve 341. When the compression spring is in the initial state, the gasket is engaged with the outer bottom wall of the button sleeve 341 to prevent the button cover 342a from falling off the button sleeve 341. The limiting part 344 can also include a nut assembly and a gasket. The button rod 342b has threads. The nut assembly fixes the gasket to the part of the screw rod that extends out of the button sleeve 341. When the compression spring is in the initial state, the gasket is engaged with the outer bottom wall of the button sleeve 341 to prevent the button cover 342a from falling off the button sleeve 341.

[0045] In some embodiments, such as Figure 9 As shown, the top of the button sleeve 341 is provided with a snap-fit ​​edge 345, and the side wall of the button sleeve 341 is provided with an elastic protrusion 346. The side wall of the receiving chamber 310 is provided with a mounting hole 315. The snap-fit ​​edge 345 and the elastic protrusion 346 snap onto the side wall of the receiving chamber 310 to install the button sleeve 341 in the mounting hole 315, thus preventing the button sleeve 341 from occupying external space. It should be noted that the button sleeve 341 can also be threaded or glued to the receiving chamber 310. It should be understood that in some other implementations, the mounting hole 315 can also be provided on the cover plate 312.

[0046] Specifically, this invention discloses that the button sleeve 341 is a circular cylinder, and the mounting hole 315 is a circular hole. It should be noted that the button sleeve 341 and the mounting hole 315 can also be other shapes. For example, in some embodiments, the button sleeve 341 is a square cylinder, and the mounting hole 315 is a square hole. In some implementations, the square button sleeve 341 can be snapped into the square hole by rotation, etc. Figure 10 As shown.

[0047] It should be noted that the unlocking component 340 is not limited to the components mentioned above, and can also be other components. For example, the unlocking component 340 can be a lever, one end of which is locked outside the containment chamber 310. Specifically, a limiting crossbar for easy hand gripping can also be provided on the lever, and the limiting crossbar is locked onto the outer wall of the containment chamber 310. To prevent slippage, an anti-slip layer can be pasted or etched onto the limiting crossbar.

[0048] The other end of the lever extends into the containment chamber 310 and is hinged to the end of the connecting part 331a away from the locking part 331b. The lever and the locking part 331b are located on opposite sides of the connection point between the connecting part 331a and the containment chamber 310, forming a lever-type connection. Pulling the lever will cause the connecting part 331a to rotate away from the locking slot, releasing the latch 332.

[0049] In order to increase the locking force of the locking buckle 332, the present invention discloses that the connection point between the connecting part 331a and the receiving chamber 310 is connected by a torsion spring. When in the locked state, the torque of the torsion spring drives the connecting part 331a to move towards the slot, so that the locking part 331b can cooperate with the slot to lock the buckle 332.

[0050] For the foregoing method embodiments, in order to simplify the description, they are all described as a series of actions. However, those skilled in the art should understand that the present invention is not limited to the described order of actions, because according to the present invention, some steps can be performed in other orders or simultaneously. Furthermore, those skilled in the art should also understand that the embodiments described in the specification are preferred embodiments, and the actions and modules involved are not necessarily essential to the present invention.

[0051] It should also be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably.
