Interlocking module, vaporizer and anesthesia machine

Abstract

The embodiment of the present application provides an interlocking module, an evaporator and an anesthesia machine. The interlocking module comprises a mounting seat, a knob, an ejection assembly, a connecting rod assembly and an ejection piece. The ejection piece is in sliding connection with the mounting seat. The connecting rod assembly is arranged between the knob and the ejection assembly. The connecting rod assembly comprises a follower and a linkage. The follower is connected with the knob. When the knob rotates, the follower can drive the linkage to move. The linkage further drives the ejection piece to move outwardly from the mounting seat, so that the ejection piece moves from an initial position to an interlocking position. The ejection pieces of two evaporators are arranged at intervals. When an operator rotates one of the evaporators, the corresponding ejection piece extends and abuts against the ejection piece of the other evaporator, thereby limiting the movement of the ejection piece. Thus, the rotation of the knob of the other evaporator is further limited, and the simultaneous use of two anesthetics is avoided.

Description

Technical Field

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

[0002] In inhalation anesthesia, liquid anesthetics—such as enflurane, isoflurane, sevoflurane, and desflurane—are typically vaporized and delivered to the patient via a vaporizer in the anesthesia delivery system. For ease of use, multiple anesthetics are often prepared simultaneously, requiring multiple vaporizers to vaporize different anesthetics. However, only one anesthetic can be administered to the patient at a time during anesthesia; therefore, it is essential to ensure that only one vaporizer's anesthetic is delivered to the patient at any given time. Summary of the Invention

[0003] This invention provides an interlocking module, a vaporizer, and an anesthesia machine to solve the problem in the prior art where dual-tank anesthesia machines may deliver two anesthetic agents to a patient simultaneously during use.

[0004] According to a first aspect, embodiments of the present invention provide an interlocking module, comprising:

[0005] Mounting base;

[0006] Knob;

[0007] An ejector assembly includes an ejector member slidably connected to the mounting base;

[0008] A linkage assembly is provided between the knob and the ejector assembly. The linkage assembly includes a follower and a linkage. The follower is connected to the knob. When the knob is rotated, the follower can drive the linkage to move. The linkage then drives the ejector to move outward from the mounting base, so that the ejector moves from the initial position to the interlocked position.

[0009] As a further optional solution for the interlocking module, there are two ejector pieces with their ends facing each other and their axes aligned on the same straight line. When the knob drives the linkage to move, the linkage can enter between the two ejector pieces, causing the two ejector pieces to move toward the interlocking position in opposite directions.

[0010] As a further optional solution for the interlocking module, the interlocking module also includes a first reset member, which is disposed between the ejector and the mounting base. The first reset member can deform when the ejector moves to the interlocking position, and after the force applied by the linkage to the ejector is removed, it drives the ejector to reset.

[0011] As a further optional solution for the interlocking module, the knob is provided with a guide structure, and one end of the follower is slidably connected to the guide structure. When the knob is rotated, the guide structure can drive the end of the follower to move closer to or away from the center of the knob, and the follower in turn drives the linkage to move.

[0012] As a further optional solution for the interlocking module, the linkage assembly includes a first linkage and a second linkage. The first linkage constitutes the follower, and the second linkage constitutes the linkage. One end of the first linkage is connected to the guide structure, and the other end of the first linkage is connected to the second linkage. The middle part of the first linkage is rotatably connected to the external structure.

[0013] As a further optional solution for the interlocking module, the interlocking module also includes a second reset member, which is disposed between the mounting base and the linkage member. When the knob drives the linkage member to move, the second reset member deforms to generate elastic force. The elastic force generated on the second reset member can make the linkage assembly tend to reset.

[0014] As a further optional embodiment of the interlocking module, the interlocking module further includes:

[0015] A handle assembly is movably connected to the mounting base. The handle assembly can move between a locked position and an unlocked position. When the handle assembly is in the locked position, it can limit the movement of the linkage assembly, so that the linkage assembly and the knob are in a locked state. When the handle assembly is in the unlocked position, it can release the restriction on the movement of the linkage assembly, so that the linkage assembly and the knob are in an unlocked state.

[0016] A limiting component is disposed on the mounting base, the limiting component being able to hold the handle assembly in the locked position and also being able to hold the handle assembly in the unlocked position.

[0017] As a further optional solution for the interlocking module, the handle assembly is disposed radially on the linkage member, and the side wall of the handle assembly can limit the movement of the linkage member when the handle assembly is in the locked position; a relief portion is formed on the handle assembly, and the relief portion can avoid the movement of the linkage member when the handle assembly is in the unlocked position, so that the linkage assembly and the knob are in the unlocked state.

[0018] According to a second aspect, embodiments of the present invention provide an evaporator, including a tank, a regulating valve, and an interlocking module as described in any of the foregoing embodiments. The regulating valve is disposed in the tank, and a knob is connected to the regulating valve such that the regulating valve can be opened or closed when the knob is turned. The mounting base is connected to the tank.

[0019] According to a third aspect, embodiments of the present invention provide an anesthesia machine, including an anesthesia machine body, a connecting seat, and a vaporizer as described in any of the foregoing embodiments. The number of vaporizers is set to two, and the ejector parts of the two vaporizers are spaced apart. When the ejector part of one vaporizer is in an interlocked position, it can press against the ejector part of the other vaporizer, thereby limiting the ejector part of the other vaporizer and preventing it from moving.

[0020] Implementing the embodiments of the present invention will have the following beneficial effects:

[0021] This interlock module slides the ejector onto the mounting base and connects the linkage assembly between the knob and the ejector, so that the movement state of the knob and the movement state of the ejector are correlated, thus enabling two adjacent devices (such as evaporators) to have an interlock function. It has a simple structure, high reliability, and strong stability.

[0022] The evaporator uses an interlock module that connects the knob to the regulating valve. The turning motion of the knob controls the opening and closing of the regulating valve. The linkage assembly is connected between the knob and the ejector, so that the movement state of the knob and the movement state of the ejector are related, thus enabling two adjacent evaporators to have an interlock function.

[0023] The anesthesia machine uses a vaporizer with an interlocking module, with the ejector parts of the two vaporizers spaced apart. When the operator turns one vaporizer, the corresponding ejector part extends and abuts against the ejector part of the other vaporizer, thus restricting the movement of the ejector part. This further restricts the rotation of the knob of the other vaporizer, avoiding the simultaneous use of two anesthetics. Attached Figure Description

[0044] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many other different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0045] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0047] This invention provides an interlocking module, a vaporizer, and an anesthesia machine to solve the problem in the prior art where dual-tank anesthesia machines may deliver two anesthetic agents to a patient simultaneously during use.

[0048] In the embodiments of the present invention, please refer to the references. Figure 1 and Figure 4 The interlocking module includes: a mounting base 10, a knob 20, an ejector assembly 90, and a linkage assembly 50; wherein, the ejector assembly 90 includes an ejector 91, which is slidably connected to the mounting base 10; the linkage assembly 50 is disposed between the knob 20 and the ejector assembly 90, and the linkage assembly 50 includes a follower and a linkage. The follower is connected to the knob 20. When the knob 20 is rotated, it can drive the linkage to move through the follower, and the linkage will then drive the ejector 91 to move outward from the mounting base 10, so that the ejector 91 moves from the initial position to the interlocked position.

[0049] In the embodiments of the present invention, please refer to the references. Figure 1 , Figure 4 and Figure 5 The evaporator includes a tank 60, a regulating valve 70, and the aforementioned interlocking module. The regulating valve 70 is located inside the tank 60. The knob 20 is connected to the regulating valve 70, so that the regulating valve 70 can be opened or closed when the knob 20 is turned. The mounting base 10 is connected to the tank 60.

[0050] In the embodiments of the present invention, please refer to Figure 1 The anesthesia machine includes the main body of the anesthesia machine (not shown in the figure), the connecting seat 80 and the aforementioned vaporizer. The number of vaporizers is set to two, and the ejector parts 91 of the two vaporizers are arranged at intervals. When the ejector part 91 of one vaporizer is in the interlocked position, it can press against the ejector part 91 of the other vaporizer, so that the ejector part 91 of the other vaporizer is limited and cannot move.

[0051] The anesthesia machine is used as follows: Take two vaporizers and install the mounting bases 10 of the two vaporizers onto the connecting base 80, so that the ejector parts 91 on the two mounting bases 10 are spaced apart; during the administration of anesthesia, the operator turns the knob 20 of one of the vaporizers. The movement of the knob 20 acts on the connecting rod assembly 50, causing the follower of the connecting rod assembly 50 to drive the linkage to move. The linkage further drives the ejector part 91 to be ejected. The ejector part 91 presses against the ejector part 91 of the other vaporizer, so that the ejector part 91 is limited and cannot move. The limited state of the ejector part 91 acts on the knob 20 through the connecting rod assembly 50, so that the knob 20 cannot be turned. Therefore, during the operation, the operator can only turn one vaporizer at a time.

[0052] The interlock module slides the ejector 91 onto the mounting base 10 and connects the connecting rod assembly 50 between the knob 20 and the ejector 91, so that the movement state of the knob 20 is related to the movement state of the ejector 91, thereby enabling two adjacent devices (such as evaporators) to have an interlock function. It has a simple structure, high reliability, and strong stability.

[0053] The evaporator uses an interlock module that connects the knob 20 to the regulating valve 70. The turning motion of the knob 20 controls the opening and closing of the regulating valve 70. The connecting rod assembly 50 is connected between the knob 20 and the ejector 91, so that the movement state of the knob 20 and the movement state of the ejector 91 are related to each other, thus enabling two adjacent evaporators to have an interlock function.

[0054] The anesthesia machine uses a vaporizer with an interlocking module. The ejector parts 91 of the two vaporizers are set at intervals. When the operator turns one of the vaporizers, the corresponding ejector part 91 extends and abuts against the ejector part 91 of the other vaporizer, thereby restricting the movement of the ejector part 91. This further restricts the rotation of the knob 20 of the other vaporizer, avoiding the use of two anesthetics at the same time.

[0055] For instructions on how to configure the pop-out component 90, please refer to [link / reference]. Figure 4In one embodiment, two ejector pieces 91 are provided, with their ends facing each other and their axes aligned on the same straight line. When the knob 20 drives the linkage to move, the linkage can enter between the two ejector pieces 91, causing the two ejector pieces 91 to move toward the interlocked position in opposite directions.

[0056] The advantage of this embodiment is that when the interlock module is installed on the evaporator, the ejector 91 can function on both sides of the evaporator. Compared to the method of setting only one ejector 91, the two evaporators with two ejector 91 do not need to be deliberately distinguished in position during installation, making the installation simpler. Moreover, the evaporators manufactured using this solution are exactly the same, eliminating the need to manufacture different molds, making the production process simpler and the cost lower.

[0057] In one specific embodiment, the ejector assembly 90 further includes a first reset member 92, which is disposed between the ejector 91 and the mounting base 10. The first reset member 92 can deform when the ejector 91 moves to the interlock position, and after the force applied to the ejector 91 by the linkage member is removed, it drives the ejector 91 to reset.

[0058] In a more specific embodiment, the mounting base 10 has an ejector mounting hole that runs straight through the mounting base 10. Two ejectors 91 are slidably connected in the ejector mounting hole with one end facing each other, and their ends are exposed on both sides of the mounting base 10. An annular groove is formed on the side wall of the ejector 91, and a C-shaped retaining ring 911 is provided in the annular groove. Two sealing members 13 are provided on the mounting base 10. The two sealing members 13 are respectively provided at the two openings of the ejector mounting hole, and the sealing members 13 are sleeved on the outer surface of the ejector 91. The first reset member 92 is a spring, one end of which abuts against the C-shaped retaining ring 911, and the other end abuts against the sealing member 13.

[0059] In this embodiment of the invention, the linkage assembly 50 refers to a mechanism composed of multiple (two or more) components with definite relative motion connected by lower pairs (revolute joints or prismatic joints). Its function is to link the position state of the ejector assembly 90 with the rotational degree of freedom of the knob 20. Due to the flexibility of the linkage assembly 50 in practice, this specification can only describe some preferred embodiments. Linkage assemblies 50 that are not listed but conform to the above functional description should also be considered to fall within the protection scope of this invention.

[0060] In one embodiment, the knob 20 is provided with a guide structure 21, and one end of the follower is slidably connected to the guide structure 21. When the knob 20 is rotated, the guide structure 21 can drive the end of the follower to move closer to or away from the center of the knob 20, and the follower in turn drives the linkage to move.

[0061] In one specific embodiment, please refer to the reference. Figures 2 to 5 The linkage assembly 50 includes a first linkage 51 and a second linkage 52. The first linkage 51 constitutes a follower, and the second linkage 52 constitutes a linkage. One end of the first linkage 51 is connected to the guide structure 21, and the other end of the first linkage 51 is connected to the second linkage 52. The middle part of the first linkage 51 is rotatably connected to an external structure (such as a mounting plate rotatably connected to the tank 60 of the evaporator).

[0062] The advantage of this embodiment is that the linkage assembly 50 consists of only two components, which is simple in structure and can reduce installation difficulty and production cost.

[0063] In another specific embodiment, please refer to Figure 7 The linkage assembly 50 includes a first link 53, a second link 54, a third link 55, and a sliding ring 56. One end of the second link 54 is connected to the guide structure 21, and the other end is rotatably connected to the end of the first link 53. One end of the third link 55 is rotatably connected to the middle of the second link 54, and the other end is rotatably connected to the sliding ring 56, which is slidably connected to the first link 53. In this configuration, the second link 54 acts as a follower, while the first link 53, the third link 55, and the sliding ring 56 act as a linkage.

[0064] For the configuration of guide structure 21, please refer to [reference needed]. Figure 6 In one specific embodiment, the guide structure 21 is configured as a guide groove 211, and the first end of the connecting rod assembly 50 is slidably connected in the guide groove 211. It should be noted that the guide groove 211 should have a portion that is further away from the center of the knob 20 than other portions, so that when the knob 20 is rotated, the guide groove 211 can drive the first end of the connecting rod assembly 50 to move closer to or further away from the center of the knob 20.

[0065] In another, more specific embodiment, the guide structure 21 is configured as a slide rail, the end of the first link 51 is slidably connected to the slide rail, and moves along the slide rail toward or away from the center of the knob 20 when the knob 20 is rotated.

[0066] In one embodiment, the interlock module further includes a second reset member 100, which is disposed between the mounting base 10 and the linkage member. When the knob 20 drives the linkage member to move, the second reset member 100 deforms to generate a spring force. The spring force generated on the second reset member 100 can make the linkage assembly 50 tend to reset.

[0067] In conjunction with the aforementioned implementation of the linkage assembly 50, please refer to the reference. Figures 3 to 5In one specific embodiment, the linkage assembly 50 includes a first linkage 51 and a second linkage 52; the second reset member 100 is configured as a reset spring, which is sleeved on the outer surface of the second linkage 52. The mounting base 10 has a first mounting hole 11 and a second mounting hole 12 that are connected. The reset spring is inserted into the first mounting hole 11, and the second linkage 52 is inserted into the second mounting hole 12. A protrusion 521 is formed on the outer surface of the second linkage 52. One end of the reset spring abuts against the protrusion 521, and the other end abuts against the bottom wall of the first mounting hole 11. It should be noted that in this embodiment, since the reset spring can drive the second linkage 52 to move, the first linkage 51 and the second linkage 52 can be interconnected or only abut against each other.

[0068] In this embodiment, the operation of the linkage assembly 50 is related to the arrangement of the guide structure 21. Depending on the arrangement of the guide structure 21, when the driving force of turning the knob 20 is removed, the linkage assembly 50 may remain in its current state (i.e., the linkage assembly 50 and the knob 20 will not move due to the action of the return spring after the driving force is removed) or it may be reset (i.e., it returns to the state before the knob 20 was turned under the action of the reset member). The following describes two specific implementation schemes assuming that the guide structure 21 is configured as a guide groove 211.

[0069] In a more specific embodiment, the guide groove 211 is configured as a straight groove, with one end close to the center of the knob 20 and the other end away from the center of the knob 20. An angle exists between the line connecting the end of the first connecting rod 51 and the center of the knob 20 and the sidewall of the guide groove 211. In the unlocked state, when the user turns the knob 20, the return spring is compressed. When the knob 20 is released, the return spring pulls the first connecting rod 51 via the second connecting rod 52. The force between the first connecting rod 51 and the guide groove 211 generates torque on the knob 20, thereby causing the knob 20 to reset.

[0070] The advantage of this embodiment is that during the administration of anesthesia, the operator needs to continuously apply force to the knob 20, and when the operator's hand leaves the knob 20, the knob 20 will automatically reset, avoiding the situation where the operator forgets to close the regulating valve 70, and further reducing the possibility of anesthetic leakage.

[0071] In another, more specific embodiment, please refer to Figure 6The guide groove 211 includes a surrounding portion 2111 equidistant from the center of the knob 20 and an extension portion 2112 formed by the outward deflection of the end of the surrounding portion 2111. The end of the first connecting rod 51 can move within the surrounding portion 2111 and the extension portion 2112, thus moving closer to or further away from the center of the knob 20. The evaporator is used as follows: when the end of the first connecting rod 51 is in the extension portion 2112, the regulating valve 70 is closed. When the user turns the knob 20 so that the end of the first connecting rod 51 enters the surrounding portion 2111, the regulating valve 70 opens. If the user removes the driving force on the knob 20, the direction of the force between the end of the first connecting rod 51 and the surrounding portion 2111 passes through the center of the knob 20, meaning that no torque can be generated on the knob 20, and the connecting rod assembly 50 and the knob 20 remain in their current state. To close the regulating valve 70, the user needs to turn the knob 20 back so that the end of the first connecting rod 51 re-enters the extension portion 2112.

[0072] The advantage of this embodiment is that the user does not need to keep one hand on the knob 20 during the anesthesia process, making it easier to operate; at the same time, the force between the end of the first link 51 and the surrounding part 2111 has a certain maintaining effect on the position of the knob 20, so that the knob 20 will not easily rotate due to external disturbances other than the user, thereby avoiding changes in the release rate of the anesthetic.

[0073] Those skilled in the art can freely choose between the two solutions described above as needed. It should be noted that the guide groove 211 is not limited to only these two forms; the descriptions using these two examples are merely for illustrative purposes. Those skilled in the art can still make appropriate modifications to the specific form of the guide groove 211 to achieve the same or substantially the same effect.

[0074] In one specific embodiment, please refer to the reference. Figures 2 to 5 The interlocking module also includes a handle assembly 30 and a limiting assembly 40. The handle assembly 30 is movably connected to the mounting base 10 and can move between a locked position and an unlocked position. When the handle assembly 30 is in the locked position, it can limit the movement of the linkage assembly 50, so that the linkage assembly 50 and the knob 20 are in a locked state. When the handle assembly 30 is in the unlocked position, it can release the restriction on the movement of the linkage assembly 50, so that the linkage assembly 50 and the knob 20 are in an unlocked state. The limiting assembly 40 is disposed on the mounting base 10 and can hold the handle assembly 30 in the locked position and also hold the handle assembly 30 in the unlocked position.

[0075] When this embodiment is applied to a vaporizer, the handle assembly 30 is provided with a connection structure for connecting the handle assembly 30 to the connection seat 80 of the anesthesia machine body when the handle assembly 30 is in the unlocked position. The evaporator is used as follows: When the evaporator is not connected to the connecting seat 80, the handle assembly 30 is locked by the limiting assembly 40. The handle assembly 30 limits the connecting rod assembly 50, making the connecting rod assembly 50 locked and unable to move. Due to the linkage between the movement of the connecting rod assembly 50 and the knob 20, the knob 20 is also locked, meaning the operator cannot turn the knob 20, thus preventing leakage of the anesthetic. When the evaporator needs to be used, the operator needs to place the evaporator mounting base 10 on the connecting seat 80 and move the handle assembly 30 from the locked position to the unlocked position. This allows the handle assembly 30 to be connected to the connecting seat 80 through the connecting structure. The handle assembly 30 releases the limiting of the connecting rod assembly 50, thus changing the connecting rod assembly 50 and the knob 20 from the locked state to the unlocked state. The operator can then release the anesthetic in the evaporator by turning the knob 20.

[0076] In this embodiment, the position of the handle assembly 30 is related to the connection status of the vaporizer and the connector 80. Before turning on the vaporizer, the user must first move the handle assembly 30 from the locked position to the unlocked position. This process simultaneously connects the vaporizer to the connector 80, after which the vaporizer can be turned on smoothly. This avoids the problem of anesthetic leakage caused by accidental operation of the vaporizer knob 20 when the vaporizer is not connected to the main body of the anesthesia machine. Combined with the aforementioned solution, the anesthesia machine can simultaneously prevent the simultaneous release of two anesthetics and prevent anesthetic leakage, thereby greatly improving the safety of use.

[0077] The handle assembly 30 can limit the linkage in various ways. For the sake of explanation, this description is based on the embodiment of the linkage assembly 50 including the first linkage 51 and the second linkage 52. Those skilled in the art can adapt and apply the following limiting methods to linkage assemblies 50 with different designs. They will not be described in detail here.

[0078] In a more specific embodiment, please refer to Figure 5 The handle assembly 30 is disposed radially on the second link 52. The side wall of the handle assembly 30 can limit the movement of the second link 52 when the handle assembly 30 is in the locked position. A clearance part is formed on the handle assembly 30. The clearance part can clear the movement of the second link 52 when the handle assembly 30 is in the unlocked position, so that the link assembly 50 and the knob 20 are in the unlocked state.

[0079] In a further specific embodiment, the handle assembly 30 includes a first segment 331 and a second segment 332. The diameter of the second segment 332 is larger than the diameter of the first segment 331. The first segment 331 forms a clearance portion, and the sidewall of the second segment 332 can limit the movement of the second link 52 when the handle assembly 30 is in the locked position. More specifically, the second link 52 is provided with a recess 522. When the handle assembly 30 is in the locked position, the second segment 332 is embedded in the recess 522. More specifically, the handle assembly 30 includes a handle 31, a central shaft 32, and a sleeve 33. The handle 31 provides a gripping position for the operator and is connected to the top of the central shaft 32. The sleeve 33 is fitted onto the outer surface of the central shaft 32, and the first segment 331 and the second segment 332 are formed on the sleeve 33.

[0080] In another more specific embodiment, a clearance groove or clearance hole is provided on the side wall of the handle assembly 30. The clearance groove or clearance hole constitutes the aforementioned clearance part. When the handle assembly 30 is in the unlocked position, the second link 52 can pass through the clearance groove or clearance hole when it moves.

[0081] In another, more specific embodiment, the handle assembly 30 is provided with a connector comprising a first portion extending radially along the handle assembly 30 and a second portion perpendicular to the first portion (as shown in the attached image). Figure 5 Taking the position of the handle assembly 30 as an example, the connector should be located below the second link 52 in space. The first part of the connector extends horizontally and the second part extends vertically upward. The second link 52 has a connector hole. When the handle assembly 30 is in the locked position, the second part is inserted into the connector hole. When the handle assembly 30 is in the unlocked state, the second part is removed from the connector hole.

[0082] In one specific embodiment, the limiting component 40 includes a limiting member 41 and a limiting spring 42. The limiting member 41 is disposed on the mounting base 10. A mating groove 333 is formed on the handle assembly 30. The mating groove 333 includes a vertically extending vertical section 3331 and a horizontally extending horizontal section 3332. The limiting member 41 is inserted into the mating groove 333. The limiting spring 42 is disposed between the handle assembly 30 and the mounting base 10. One end of the limiting spring 42 is connected to the handle assembly 30, and the other end of the limiting spring 42 is connected to the mounting base 10. In its natural state, the limiting spring 42 can support the handle assembly 30 in a locked position. The handle assembly 30 can move downward and rotate under the action of driving force, so that the limiting member 41 moves from the vertical section 3331 into the horizontal section 3332, and the limiting spring 42 changes from its natural state to a compressed state.

[0083] In another specific embodiment, the limiting component 40 includes a limiting bolt and a spring. The limiting bolt is slidably connected to the mounting base 10, and the spring is sleeved on the limiting bolt. One end of the spring is connected to the limiting bolt, and the other end is connected to the mounting base 10. The handle assembly 30 has a first mating hole corresponding to the locking position and a second mating hole corresponding to the unlocking position. In the spring's natural state, the spring presses the phase bolt against the handle assembly 30, causing the end of the limiting bolt to enter the first mating hole or the second mating hole. When the operator needs to change the position of the handle assembly 30, the limiting bolt needs to be pulled, causing the end of the limiting bolt to leave the first mating hole or the second mating hole. After the position of the handle assembly 30 is adjusted, the limiting bolt is released, and the spring applies a pushing force to the limiting bolt, causing it to enter the first mating hole or the second mating hole.

[0084] In another specific embodiment, the limiting component 40 includes a limiting bolt, which is fixedly connected to the mounting base 10. The handle component 30 has a sliding groove, which includes a first groove, a second groove, and a third groove. The first groove and the third groove extend horizontally, and the second groove extends vertically and connects between the first groove and the third groove, so that the sliding groove is approximately "Z" shaped. When the limiting bolt is located in the first groove or the third groove, the handle component 30 is in a locked state or an unlocked state.

[0085] Regarding the connection method between the handle assembly 30 and the connecting seat 80, in one embodiment, the connection structure on the handle assembly 30 is set as a connecting groove 34, and the connecting seat 80 is provided with an "S"-shaped spring (not shown in the figure). By pressing down and rotating the handle assembly 30, the "S"-shaped spring can be connected to the connecting groove 34.

[0086] In another embodiment, the connecting structure on the handle assembly 30 is provided with an external thread, and the connecting seat 80 is provided with an internal thread. The handle assembly 30 is connected to the connecting seat 80 through the engagement of the internal thread and the external thread.

[0087] In another embodiment, the lower side surface of the handle assembly 30 protrudes outward to form a convex ring, and the connecting seat 80 is provided with a slot. When connecting the vaporizer and the anesthesia machine body, the mounting seat 10 is placed on the connecting seat 80, and the handle assembly 30 is pressed down so that the convex ring is inserted into the slot, thus completing the connection. During this process, the handle assembly 30 also moves from the locked position to the unlocked position.

[0088] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0089] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
