Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and particularly to a medical device, an anesthesia machine and a locking device thereof. Background Art

[0002] In actual application scenarios of medical devices, it is often necessary to disassemble and assemble the host or functional modules. Taking an anesthesia machine as an example, the anesthesia machine is used to provide gas anesthesia and respiratory support to patients during surgery. When the anesthesia machine is working, the gas flows through the internal pipeline of the respiratory circuit of the anesthesia machine and then enters the patient's body. Since the respiratory circuit belongs to a high-humidity environment and is prone to bacterial growth, and cross-infection may occur between different patients, it is necessary to disinfect the respiratory circuit. Usually, the respiratory circuit is disassembled and soaked or sterilized by high-temperature steaming. Therefore, the respiratory circuit should be convenient to disassemble and install. At the same time, to prevent misoperation, a locking mechanism is designed on the patient circuit main body of the respiratory circuit. The respiratory circuit needs to be locked by the locking mechanism during normal use, and the locking of the locking mechanism needs to be manually released before disassembling the respiratory circuit, and then the disassembly can be carried out.

[0003] Some existing locking mechanisms require the operator to perform locking and unlocking operations in a purely manual manner. Using such a locking mechanism, it is easy for the operator to forget to manually lock after installing the respiratory circuit, resulting in risks in clinical use. To reduce the risk of forgetting to lock, some locking mechanisms achieve automatic locking through a first elastic member, and when unlocking, the operator needs to press an unlocking button to unlock the locking mechanism. Although this solution can avoid the risk of forgetting to lock, during the process of disassembling the respiratory circuit, the operator needs to always maintain the posture of pressing the unlocking button with one hand and can only use the other hand to disassemble the respiratory circuit, which brings inconvenience to the operator's disassembly action. Especially in some anesthesia machines, a large pulling force is required to disassemble the respiratory circuit, which makes it particularly difficult for the operator to disassemble with one hand. Summary of the Invention

[0004] The main technical problem to be solved by the present invention is that when disassembling the respiratory circuit of the existing anesthesia machine, the operator needs to always maintain the posture of pressing the unlocking button with one hand and can only use one hand to perform the disassembly action, which brings inconvenience to the operator's disassembly operation.

[0005] In a first aspect, in one embodiment, an anesthesia machine is provided, including:

[0006] An anesthesia machine host;

On the one hand, since the locking tongue driving mechanism can drive the locking tongue to remain in the unlocking position after being initially triggered, the staff can use both hands to perform the detachment work on the breathing circuit, which is beneficial to reducing the difficulty of the detachment work. On the other hand, after the breathing circuit is reinstalled to the anesthesia machine main body, it can be automatically locked to the anesthesia machine main body, thus avoiding the risk that the staff forgets to lock the breathing circuit to the anesthesia machine main body. Or, during the process of the staff detaching the suction circuit from the anesthesia main body, the locking tongue driving mechanism will be automatically triggered a second time, so that the locking tongue driving mechanism drives the locking tongue to move from the unlocking position to the locking position, thus preparing for the staff to reinstall the breathing circuit subsequently.

Detailed implementation manners

[0062] The present invention will be further described in detail below in conjunction with the accompanying drawings through specific implementation manners. Similar elements in different implementation manners are labeled with related similar reference numerals. In the following implementation manners, many details are described to enable a better understanding of the present application. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification to avoid the core part of the present application being overwhelmed by excessive description. For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0063] In addition, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. Meanwhile, the steps or actions in the method description can also be reordered or adjusted in a manner obvious to those skilled in the art. Therefore, the various sequences in the specification and drawings are only for clearly describing a certain embodiment and do not mean a necessary sequence, unless it is stated otherwise that a certain sequence must be followed.

[0064] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the objects described and do not have any sequential or technical meaning. And as used in this application, "connection" and "coupling", unless otherwise specified, both include direct and indirect connection (coupling).

[0065] This embodiment provides an anesthesia machine.

[0066] Please refer to Figures 1-7 , this anesthesia machine includes an anesthesia machine main unit (not shown), a breathing circuit 2000, and a locking control device 1000.

[0067] The breathing circuit 2000 is detachably connected to the anesthesia machine main unit. The locking control device 1000 is disposed between the anesthesia machine main body and the breathing circuit 2000. The locking control device 1000 includes a locking control base body 100, a locking tongue 200, and a locking tongue driving mechanism 300. The locking tongue 200 is movably disposed in the locking control base body 100, and the locking tongue 200 can move between a locked position and an unlocked position. The locking control device 1000 is used to lock the breathing circuit 2000 to the anesthesia machine main unit when the locking tongue 200 moves to the locked position, and to unlock the breathing circuit 2000 from the anesthesia machine main unit when the locking tongue 200 moves to the unlocked position. The locking tongue driving mechanism 300 is connected to the locking tongue 200. The locking tongue driving mechanism 300 is used to drive the locking tongue 200 to move to the unlocked position when initially triggered, and the locking tongue 200 remains in the unlocked position until the locking tongue driving mechanism 300 is triggered a second time. The locking tongue driving mechanism 300 can be automatically triggered a second time during the process of detaching the breathing circuit 2000 from the anesthesia machine main unit or when the breathing circuit 2000 is reinstalled on the anesthesia machine main unit after being detached, so as to drive the locking tongue 200 to move from the unlocked position to the locked position.

[0068] It should be noted that the meaning of the "locking tongue" in each embodiment of this application is not limited to the locking tongue in the traditional door lock mechanism. It should be regarded as a locking tongue of a "locking device" in a broader sense that can be applied to any device. For example, a locking device usually has a clamping member that can move out and retract, and this clamping member is used to engage with a card slot on another object to achieve the locking of the other object. Then, in a broad sense, this clamping member can be regarded as the "locking tongue".

[0069] Please continue to refer to Figures 1-7, when the staff needs to disassemble the breathing circuit 2000 from the main body of the anesthesia machine, the tongue driving mechanism 300 can be triggered once. The tongue driving mechanism 300 drives the tongue 200 to move from the locked position to the unlocked position, and the tongue 200 will remain stationary at the unlocked position, so that the staff can use both hands to remove the breathing circuit 2000 from the main body of the anesthesia machine. When the staff completes the disinfection or maintenance work of the anesthesia machine, the breathing circuit 2000 can be reinstalled onto the main body of the anesthesia machine. At this time, the tongue driving mechanism 300 will be automatically triggered a second time, so that the tongue driving mechanism 300 drives the tongue 200 to move from the unlocked position to the locked position, thereby realizing the automatic locking of the breathing circuit 2000 and the main body of the anesthesia machine. On the one hand, since the tongue driving mechanism 300 can drive the tongue 200 to remain at the unlocked position after being initially triggered, it enables the staff to use both hands to disassemble the breathing circuit 2000, which is beneficial to reducing the difficulty of the disassembly work. On the other hand, after the breathing circuit 2000 is reinstalled onto the main body of the anesthesia machine, it can be automatically locked with the main body of the anesthesia machine, thus avoiding the risk that the staff forgets to lock the breathing circuit 2000 with the main body of the anesthesia machine. Or, during the process of the staff disassembling the breathing circuit 2000 from the main body of the anesthesia machine, the tongue driving mechanism 300 will be automatically triggered a second time, so that the tongue driving mechanism 300 drives the tongue 200 to move from the unlocked position to the locked position, thereby preparing for the staff to reinstall the breathing circuit 2000 subsequently.

[0070] It should be noted that the tongue driving mechanism 300 can keep the tongue 200 stationary at the unlocked position through a pure mechanical transmission structure, or can keep the tongue 200 stationary at the unlocked position through an electric drive structure. For example, the tongue driving mechanism 300 uses a clamping connection, a damping fit, a magnetic attraction fit or other suitable mechanical structures to keep the tongue 200 at the unlocked position. Another example is that the tongue driving mechanism 300 can use a linear motor, and the tongue 200 is kept at the unlocked position through the self-locking characteristic of the linear motor.

[0071] On the other hand, this embodiment also provides a lock control device 1000.

[0072] The lock control device 1000 is used to be arranged between a first object and a second object. The first object and the second object can be the main body of the anesthesia machine and the breathing circuit 2000 as described above, or can be other medical devices and medical modules.

[0073] Please refer to Figures 1-7 , the lock control device 1000 includes a lock control base body 100, a tongue 200 and a tongue driving mechanism 300.

[0074] The locking tongue 200 is movably arranged on the locking base body 100, and the locking tongue 200 can move between a locking position and an unlocking position. The locking device 1000 is used to lock the first object and the second object when the locking tongue 200 moves to the locking position, and unlock the first object and the second object when the locking tongue 200 moves to the unlocking position. The locking tongue driving mechanism 300 is connected to the locking tongue 200. The locking tongue driving mechanism 300 is used to drive the locking tongue 200 to move to the unlocking position when initially triggered, and the locking tongue 200 remains in the unlocking position until the locking tongue driving mechanism 300 is triggered a second time. The locking tongue driving mechanism 300 can be automatically triggered a second time during the process of disassembling the second object from the first object or when the second object is reinstalled on the first object after being disassembled, so as to drive the locking tongue 200 to move from the unlocking position to the locking position.

[0075] When the staff needs to disassemble the second object from the first object, the locking tongue driving mechanism 300 can be triggered once first. The locking tongue driving mechanism 300 drives the locking tongue 200 to move from the locking position to the unlocking position, and the locking tongue 200 will remain stationary in the unlocking position, so that the staff can use both hands to disassemble the second object from the first object. When the staff completes the disinfection or maintenance work on the anesthesia machine, the second object can be reinstalled on the first object. At this time, the locking tongue driving mechanism 300 will be automatically triggered a second time, so that the locking tongue driving mechanism 300 drives the locking tongue 200 to move from the unlocking position to the locking position, thus realizing the automatic locking of the second object and the first object. On the one hand, since the locking tongue driving mechanism 300 can drive the locking tongue 200 to remain in the unlocking position after being initially triggered, it enables the staff to use both hands to disassemble the second object, which is beneficial to reducing the difficulty of the disassembly work. On the other hand, after the second object is reinstalled on the first object, it can be automatically locked with the first object, thus avoiding the risk that the staff forgets to lock the second object with the first object. Or, during the process of the staff disassembling the second object from the first object, the locking tongue driving mechanism 300 will be automatically triggered a second time, so that the locking tongue driving mechanism 300 drives the locking tongue 200 to move from the unlocking position to the locking position, thus preparing for the staff to reinstall the second object later.

[0076] Please refer to Figures 2-5, in one embodiment, the bolt driving mechanism 300 includes a first elastic member 310, a primary trigger assembly 320, an unlocking and holding assembly 330, and a secondary trigger assembly 340. One end of the first elastic member 310 abuts against the lock control base body 100, and the other end abuts against the bolt 200. The elastic restoring force of the first elastic member 310 is used to drive the bolt 200 to move towards the locking position. The primary trigger assembly 320 is movably disposed on the lock control base body 100 and is connected to the bolt 200. The primary trigger assembly 320 can drive the bolt 200 to move to the unlocking position under the action of an external force. The unlocking and holding assembly 330 is used to contact the bolt 200 located at the unlocking position to prevent the bolt 200 from moving. The secondary trigger assembly 340 is movably disposed on the lock control base body 100. The secondary trigger assembly 340 is used to be automatically triggered during the process of detaching the breathing circuit 2000 from the anesthesia machine main body. When the secondary trigger assembly 340 is triggered, it can drive the unlocking and holding assembly 330 to disengage from the bolt 200 located at the unlocking position, so that the bolt 200 moves to the locking position under the drive of the first elastic member 310.

[0077] Since the unlocking and holding assembly 330 keeps the bolt 200 in the unlocking position through mechanical contact, the unlocking and holding assembly 330 does not increase the electrical control complexity of the anesthesia machine and is not affected by electrical control failures, thereby making the lock control device 1000 more reliable. Specifically, the unlocking and holding assembly 330 can keep the bolt 200 in the unlocking position by means of snap connection, damping cooperation, suction cup adsorption or other suitable methods. The first elastic member 310 can be a spring, a spring sheet or other suitable elastic structures, and the first elastic member 310 can generate an elastic restoring force in a compressed state or an extended state.

[0078] Please refer to Figures 2-5, during actual operation, when the staff needs to disassemble the breathing circuit 2000 from the anesthesia machine main unit, the primary trigger component 320 can be triggered first. The primary trigger component 320 drives the locking tongue 200 to move from the locked position to the unlocked position. At this time, the unlocking and holding component 330 contacts the locking tongue 200 at the unlocked position to prevent the locking tongue 200 from moving, so that the locking tongue 200 remains at the unlocked position, enabling the staff to remove the breathing circuit 2000 from the anesthesia machine main unit with both hands. During the process of the staff disassembling the breathing circuit 2000 from the anesthesia machine main unit, the secondary trigger component 340 is automatically triggered, thereby driving the unlocking and holding component 330 to disengage from the locking tongue 200 at the unlocked position through the secondary trigger component 340, so that the locking tongue 200 moves to the locked position under the drive of the first elastic member 310. When the staff reinstalls the breathing circuit 2000 onto the anesthesia machine main unit, the side wall of the breathing circuit 2000 presses against the locking tongue 200 towards the unlocked position, causing the locking tongue 200 to move to a position that does not hinder the installation of the breathing circuit 2000. This position can be set at a certain distance from the locked position, so that the locking tongue 200 will not be locked by the unlocking and holding component 330. When the breathing circuit 2000 is installed in place, the locking tongue 200 aligns with the locking groove 2100 of the breathing circuit 2000, and the elastic restoring force of the first elastic member 310 drives the locking tongue 200 to engage with the locking groove 2100 to achieve automatic locking of the locking tongue 200.

[0079] It should be noted that in this embodiment, the primary trigger of the locking tongue driving mechanism 300 refers to the staff actively triggering the primary trigger component 320, and the secondary trigger of the locking tongue driving mechanism 300 refers to the secondary trigger component 340 being automatically triggered. In other embodiments, when the locking tongue driving mechanism 300 is a motor, both the primary trigger and the secondary trigger are for the linear motor. The primary trigger can be that the staff triggers the motor through an electric control button, and the secondary trigger can be that when the breathing circuit 2000 is installed on the anesthesia machine main unit, the motor is triggered by the feedback signal of a travel switch or a photoelectric sensor. That is, "primary" and "secondary" do not refer to the first and second in an absolute quantity sense, but rather to the relatively sequential trigger operations in each repeated disassembly and installation process.

[0080] In one embodiment, the locking tongue driving mechanism 300 includes a motor (not shown), an electric control button (not shown), and a sensor assembly (not shown). The output end of the motor is connected to the locking tongue 200. The electric control button is used to start the motor when triggered, so that the motor drives the locking tongue 200 to move to the unlocked position and then self-lock. The sensor assembly is electrically connected to the motor. The sensor assembly is used to emit a feedback signal when it detects that the breathing circuit 2000 is reinstalled on the anesthesia machine main unit after being disassembled. The motor drives the locking tongue 200 to move to the locked position after receiving the feedback signal.

[0081] During the actual operation process, when the staff needs to disassemble the breathing circuit 2000 from the anesthesia machine main unit, they can first press the electric control button, so that the electrode drives the locking tongue 200 to move from the locked position to the unlocked position and then self-lock, so that the locking tongue 200 remains in the unlocked position, so that the staff can use both hands to disassemble the breathing circuit 2000 from the anesthesia machine main unit. When the staff completes the disinfection or maintenance work of the anesthesia machine, they can reinstall the breathing circuit 2000 onto the anesthesia machine main unit. At this time, the sensor assembly will be triggered, so that the sensor assembly emits a feedback signal. After receiving the feedback signal, the motor drives the locking tongue 200 to move from the unlocked position to the locked position, thereby realizing the automatic locking of the breathing circuit 2000 and the anesthesia machine main unit. Specifically, the sensor assembly can be a travel switch triggered by contact or a photoelectric sensor, etc.

[0082] Please refer to Figures 2-5 , in one embodiment, the unlocking and holding assembly 330 includes a clamping member 331 and a second elastic member 332. The clamping member 331 is movably arranged on the locking control base 100, and the locking tongue 200 has a first clamping groove 210. When the locking tongue 200 is in the unlocked position, the first clamping groove 210 is aligned with the clamping member 331, and the clamping member 331 can move closer to and away from the first clamping groove 210, so that the clamping member 331 is clamped and unclamped with the first clamping groove 210. The elastic restoring force of the second elastic member 332 is used to drive the clamping member 331 to move closer to the first clamping groove 210, so that the clamping member 331 is clamped with the first clamping groove 210.

[0083] When the locking tongue 200 moves to the unlocked position under the action of the initial triggering assembly 320, the first clamping groove 210 is aligned with the clamping member 331. At this time, the elastic restoring force of the second elastic member 332 drives the clamping member 331 to move closer to the first clamping groove 210, so that the clamping member 331 is clamped with the first clamping groove 210. The locking member is held in the unlocked position through the cooperation of the clamping member 331 and the first clamping groove 210. Specifically, the second elastic member 332 can be a spring, a spring piece or other suitable elastic structures. The second elastic member 332 can generate an elastic restoring force in a compressed state or an extended state. In other embodiments, the clamping member 331 and the first clamping groove 210 in this embodiment can also be replaced by a damping structure or a suction cup structure.

[0084] Please refer to Figures 1-3And 5, in one embodiment, the locking base 100 has a mounting groove 130, and the side of the mounting groove 130 facing the locking tongue 200 has a mounting opening 131. The clamping member 331 is movably arranged in the mounting groove 130, and the clamping member 331 can move in the mounting groove 130 to extend into or withdraw from the mounting opening 131. One end of the second elastic member 332 abuts against the inner wall of the mounting groove 130, and the other end abuts against the clamping member 331. The elastic restoring force of the second elastic member 332 is used to drive the clamping member 331 to extend out of the mounting groove 130 from the mounting opening 131.

[0085] The mounting groove 130 realizes the mounting of the clamping member 331 and the second elastic member 332 on the locking base 100. When the second elastic member 332 drives the clamping member 331 to extend out of the mounting groove 130 from the mounting opening 131, the clamping member 331 is clamped with the first clamping groove 210. When the clamping member 331 retracts into the mounting opening 131 under the action of an external force, the clamping member 331 is disengaged from the first clamping groove 210.

[0086] Please refer to Figures 1-3 Figures 5 and 6, in one embodiment, the secondary trigger assembly 340 includes an unlocking tongue 341 and an unlocking rod 342. The unlocking rod 342 is movably connected to the locking base 100. The unlocking tongue 341 is connected to the unlocking rod 342, and the unlocking rod 342 has a pressing portion 3422. The unlocking tongue 341 can drive the pressing portion 3422 of the unlocking rod 342 to move close to the clamping member 331 when being triggered, so that the clamping member 331 is disengaged from the first clamping groove 210 under the pressing of the pressing portion 3422. During the process of the breathing circuit 2000 being detached from the anesthesia machine main unit, the unlocking tongue 341 will be pressed and triggered.

[0087] When the staff detaches the breathing circuit 2000 from the anesthesia machine main unit, the breathing circuit 2000 will press and trigger the unlocking tongue 341, thereby driving the pressing portion 3422 of the unlocking rod 342 to move close to the clamping member 331 through the unlocking tongue 341, so that the pressing portion 3422 presses the clamping member 331, and further the clamping member 331 is separated from the first clamping groove 210 under the action of the pressing force. At this time, the clamping member 331 will no longer hinder the locking tongue 200 from moving to the unlocking position.

[0088] Please refer to Figures 1-3, 6 and 7, in one embodiment, the secondary trigger assembly 340 further includes a rotating screw 343. The unlocking tongue 341 is rotatably connected to the unlocking rod 342 through the rotating screw 343. The unlocking tongue 341 has a first limiting portion 3411, and the unlocking rod 342 has a second limiting portion 3421. The first limiting portion 3411 is used to contact the second limiting portion 3421 to limit the rotation angle of the unlocking tongue 341. When the unlocking tongue 341 is triggered, it has a first movement stage and a second movement stage. In the first movement stage, the unlocking tongue 341 rotates relative to the unlocking rod 342 to make the first limiting portion 3411 contact the second limiting portion 3421. In the second movement stage, the unlocking tongue 341 drives the pressing portion 3422 of the unlocking rod 342 to move closer to the clamping member 331.

[0089] When the staff reinstalls the breathing circuit 2000 onto the anesthesia machine main unit, the breathing circuit 2000 will squeeze and trigger the unlocking tongue 341, causing the unlocking tongue 341 to perform the movements of the first movement stage and the second movement stage in sequence. In the first movement stage, the unlocking tongue 341 rotates relative to the unlocking rod 342 to make the first limiting portion 3411 contact the second limiting portion 3421. At this time, due to the limiting effect of the first limiting portion 3411 and the second limiting portion 3421, the unlocking tongue 341 cannot continue to rotate relative to the unlocking rod 342. In the second movement stage, the unlocking tongue 341 drives the pressing portion 3422 of the unlocking rod 342 to move closer to the clamping member 331, so that the pressing portion 3422 drives the clamping member 331 to release the clamping with the first clamping groove 210. The rotation of the unlocking tongue 341 relative to the unlocking rod 342 plays a certain buffering role, making the unlocking tongue 341 not easily damaged under the squeezing force of the breathing circuit 2000.

[0090] Please refer to Figures 1-3 , 6 and 7, in one embodiment, the secondary trigger assembly 340 further includes a first reversing structure 345 and a second reversing structure 346. The first reversing structure 345 is arranged between the clamping member 331 and the pressing portion 3422 to change the direction of the acting force of the pressing portion 3422 on the clamping member 331. The second reversing structure 346 is arranged on the unlocking tongue 341 to change the direction of the squeezing force received by the unlocking tongue 341.

[0091] When the extrusion part 3422 extrudes the clamping part 331, the first reversing structure 345 changes the direction of the acting force of the extrusion part 3422 on the clamping part 331, so that the moving directions of the extrusion part 3422 and the clamping part 331 are not limited to being parallel to each other, which is beneficial to expanding the layout modes of the positions of the extrusion part 3422 and the clamping part 331. The second reversing structure 346 changes the direction of the extrusion force received by the unlocking tongue 341, so that when the unlocking tongue 341 is extruded, it can first rotate relative to the unlocking rod 342, and then drive the extrusion part 3422 of the unlocking rod 342 to move closer to the clamping part 331. For example, when the second reversing structure 346 is configured as the third guiding inclined plane 3461, the extrusion force acting on the third guiding inclined plane 3461 will first drive the unlocking tongue 341 to rotate, so that the first limiting part 3411 abuts against the second limiting part 3421. After that, no matter in which direction the extrusion force acts on the third guiding inclined plane 3461, a component force along the axial direction of the unlocking rod 342 will be generated, and this component force drives the extrusion part 3422 of the unlocking rod 342 to move closer to the clamping part 331, so as to achieve the effect of approximately "changing the direction of the extrusion force".

[0092] Please refer to Figures 1-3 Figures 6 and 7. In an embodiment, the first reversing structure 345 includes a first guiding inclined plane 3451 and a second guiding inclined plane 3452. The first guiding inclined plane 3451 is adapted to the second guiding inclined plane 3452. The first guiding inclined plane 3451 is located on the side of the clamping part 331 facing the extrusion part 3422, and the second guiding inclined plane 3452 is located on the extrusion part 3422. The second guiding inclined plane 3452 is used to extrude the first guiding inclined plane 3451 to guide the clamping part 331 away from the first clamping groove 210. The second reversing structure 346 includes a third guiding inclined plane 3461. The third guiding inclined plane 3461 is arranged on the unlocking tongue 341. The third guiding inclined plane 3461 is used to guide the unlocking tongue 341 to rotate and drive the extrusion part 3422 of the unlocking rod 342 to move closer to the clamping part 331 when being extruded.

[0093] When the extrusion part 3422 extrudes the clamping part 331, the first guiding inclined plane 3451 contacts the second guiding inclined plane 3452, and the clamping part 331 is guided to disengage from the first clamping groove 210 through the cooperation of the first guiding inclined plane 3451 and the second guiding inclined plane 3452. When the breathing circuit 2000 extrudes the unlocking tongue 341, the third guiding inclined plane 3461 contacts the breathing circuit 2000, so as to first guide the unlocking tongue 341 to rotate, and then guide the extrusion part 3422 of the unlocking rod 342 to move closer to the clamping part 331. Of course, in other embodiments, the above-mentioned guiding inclined plane can also be replaced by a spherical structure or a lever structure, as long as the conversion of the acting direction of the extrusion force can be realized.

[0094] Please refer to Figures 1-3, in one embodiment, the first reversing structure 345 includes a lever structure (not shown), the lever structure includes a fulcrum and a lever, the lever has a first end and a second end disposed opposite to each other, and the middle of the lever is rotatably connected to the fulcrum; the pressing portion 3422 is used to press the first end of the lever to drive the lever to rotate relative to the fulcrum, so that the second end of the lever drives the engaging member 331 away from the first engaging groove 210. Alternatively, the first reversing structure 345 includes a first spherical structure (not shown), the first spherical structure is connected to the engaging member 331 or the pressing portion 3422 to change the acting direction of the pressing force when being pressed; or, the second reversing structure 346 includes a second spherical structure (not shown), the second spherical structure is connected to the unlocking tongue 341 to change the acting direction of the pressing force when being pressed.

[0095] That is, the first guiding inclined surface 3451 and the second guiding inclined surface 3452 can be replaced by a lever structure, or the first guiding inclined surface 3451 and the second guiding inclined surface 3452 can be replaced by a first spherical structure, which can also play a role in changing the acting direction of the acting force of the pressing portion 3422 on the engaging member 331. The acting direction of the pressing force received by the unlocking tongue 341 can also be changed by the second spherical structure.

[0096] Please refer to Figures 1-3 , 6 and 7, in one embodiment, the secondary trigger assembly 340 further includes a third elastic member 344, one end of the third elastic member 344 abuts against the lock control base body 100, and the other end abuts against the unlocking rod 342. The elastic restoring force of the third elastic member 344 is used to drive the pressing portion 3422 of the unlocking rod 342 to move away from the engaging member 331.

[0097] Due to the addition of the third elastic member 344, when the breathing circuit 2000 releases the pressing on the unlocking tongue 341, the elastic restoring force of the third elastic member 344 can drive the unlocking rod 342 to move away from the second side 150 of the lock control device 1000. On the one hand, this makes the pressing portion 3422 move away from the engaging member 331 and no longer prevent the engaging member 331 from moving towards the lock tongue 200. On the other hand, it also enables the unlocking tongue 341 to extend from the locking opening 160 on the first side 140 of the lock control device 1000, thereby realizing the automatic reset of the unlocking tongue 341. Specifically, the third elastic member 344 can be a spring, a spring sheet or other suitable elastic structures, and the third elastic member 344 can generate an elastic restoring force in a compressed state or an extended state.

[0098] Please refer to Figures 1-3, 6, and 7, the breathing circuit 2000 has a locking groove 2100, and the locking base 100 has a relatively arranged first side 140 and a second side 150. The first side 140 is used to face the locking groove 2100. The locking base 100 has a locking axis parallel to the moving direction of the locking tongue 200, and the locking axis passes through the first side 140 and the second side 150. The first side 140 has a locking opening 160. When the locking tongue 200 moves to the locked position, the locking tongue 200 extends out of the locking base 100 from the locking opening 160 of the first side 140 and is engaged with the locking groove 2100. When the locking tongue 200 moves to the unlocked position, the locking tongue 200 retracts into the locking base 100 from the locking opening 160.

[0099] By reciprocating linearly the locking tongue 200 along a direction parallel to the locking axis, the locking tongue 200 is switched between the locked position and the unlocked position. When the locking tongue 200 moves to the locked position, the breathing circuit 2000 is locked to the anesthesia machine main unit through the engagement cooperation between the locking tongue 200 and the locking groove 2100. When the locking tongue 200 moves to the unlocked position, the locking tongue 200 retracts into the locking base 100 from the locking opening 160, so that the locking tongue 200 is disengaged from the locking groove 2100, so that the staff can remove the breathing circuit 2000 from the anesthesia machine main unit. Specifically, please refer to Figure 2 , the locking axis is as Figure 2 the axis L1 shown in

[0100] Please refer to Figures 1-3 , 6, and 7, in an embodiment, the locking tongue driving mechanism 300 includes an unlocking and holding component 330 and a secondary triggering component 340. The unlocking and holding component 330 includes a clamping member 331, and the secondary triggering component 340 includes an unlocking rod 342. The clamping member 331 and the unlocking rod 342 are both movably arranged in the locking base 100. The unlocking rod 342 and the locking tongue 200 are arranged adjacent to or separated from each other in the locking base 100 along a direction perpendicular to the locking axis, and the moving paths of the unlocking rod 342 and the locking tongue 200 are both parallel to the locking axis. The moving path of the clamping member 331 is perpendicular to the locking axis.

[0101] Since the moving paths of the unlocking rod 342 and the locking tongue 200 are both parallel to the locking axis, the unlocking rod 342 and the locking tongue 200 are not easily interfered with each other during movement, thereby reducing the probability of mechanical failures. Specifically, the unlocking rod 342 and the locking tongue 200 are arranged adjacent to each other in the locking base 100, and at Figure 3The unlocking rod 342 and the lock tongue 200 are arranged side by side in the horizontal direction of the lock control base 100, which makes the internal structure of the lock control base 100 more compact, thereby facilitating the reduction of the volume of the lock control device 1000. Of course, in other embodiments, when the volume limitation of the lock control device 1000 is not required, the unlocking rod 342 and the lock tongue 200 may be arranged separately, for example, the unlocking rod 342 and the lock tongue 200 may be arranged up and down, and a gap may be provided between the unlocking rod 342 and the lock tongue 200.

[0102] Please refer to Figures 1-3 , 6 and 7, in one embodiment, the lock control base 100 includes a base 110 and a cover 120, and the cover 120 is covered on the base 110 in a direction perpendicular to the locking axis. The lock tongue 200 and the unlocking rod 342 are arranged adjacently or separately in a direction perpendicular to the locking axis on the base 110, and are both parallel to the cover 120, and the clamping member 331 is located on the side of the lock tongue 200 and the unlocking rod 342 away from the cover 120. The orthographic projections of the lock tongue 200 and the unlocking rod 342 on the cover 120 do not overlap, and the orthographic projections of the clamping member 331 on the cover 120 overlap with the orthographic projections of the lock tongue 200 and the unlocking rod 342 on the cover 120.

[0103] The top of the base 110 is closed by the cover 120, so that the lock tongue 200 and the unlocking rod 342 will not be separated from the base 110 from the top of the base 110. Since the orthographic projections of the lock tongue 200 and the unlocking rod 342 on the cover 120 do not overlap, the lock tongue 200 and the unlocking rod 342 are not easy to interfere with each other when moving in a direction parallel to the locking axis. Since both the lock tongue 200 and the unlocking rod 342 need to contact the clamping member 331 and generate a force, the orthographic projection of the clamping member 331 on the cover 120 overlaps with the orthographic projections of the lock tongue 200 and the unlocking rod 342 on the cover 120.

[0104] Please refer to Figures 1-3 In one embodiment, the base 110 has a first slide groove 111 and a second slide groove 112 arranged side by side, one end of the lock tongue 200 close to the second side 150 is movably set in the first slide groove 111, and one end of the unlocking rod 342 close to the second side 150 is movably set in the second slide groove 112.

[0105] The movable setting of the locking tongue 200 on the base 110 is realized through the cooperation of the first sliding groove 111 and the locking tongue 200, and the movable setting of the unlocking rod 342 on the base 110 is realized through the cooperation of the second sliding groove 112 and the unlocking rod 342. Specifically, one end of the locking tongue 200 and the unlocking rod 342 close to the second side 150 are both arranged in a rod-shaped structure. On the one hand, this makes the fitting degree higher when the locking tongue 200 is assembled with the first sliding groove 111 and the unlocking rod 342 is assembled with the second sliding groove 112. On the other hand, when the first elastic member 310 and the second elastic member 332 are springs, the springs can be more conveniently sleeved on the rod-shaped structure.

[0106] Please refer to Figures 1-4 , in an embodiment, the initial trigger assembly 320 includes a trigger push button 322 and a trigger engaging portion 323. The trigger push button 322 and the trigger engaging portion 323 are connected. The locking tongue 200 further has a second engaging groove 220. The trigger engaging portion 323 extends into the lock control base 100 and is engaged with the second engaging groove 220. The trigger push button 322 is located outside the lock control base 100.

[0107] When it is necessary to move the locking tongue 200 to the unlocking position, the staff can push the trigger push button 322 towards the second side 150 of the lock control base 100, drive the trigger engaging portion 323 to move through the trigger push button 322, and then drive the locking tongue 200 to move from the locking position to the unlocking position through the trigger engaging portion 323. Specifically, the initial trigger assembly 320 further includes a trigger connecting portion 321. The trigger connecting portion 321 connects the trigger push button 322 and the trigger engaging portion 323. The trigger connecting portion 321 can be in the shape of a plate, a block or other suitable shapes.

[0108] On the other hand, this embodiment also provides a medical device.

[0109] Please refer to Figures 1-7 , the medical device includes a medical host, a medical module and a lock control device 1000.

[0110] The medical module is detachably connected to the medical host. A locking control device 1000 is provided between the medical host and the medical module. The locking control device 1000 includes a locking control base body 100, a locking tongue 200, and a locking tongue driving mechanism 300. The locking tongue 200 is movably arranged on the locking control base body 100, and the locking tongue 200 can move between a locking position and an unlocking position. The locking control device 1000 is used to lock the medical module to the medical host when the locking tongue 200 moves to the locking position, and to unlock the medical module from the medical host when the locking tongue 200 moves to the unlocking position. The locking tongue driving mechanism 300 is connected to the locking tongue 200. The locking tongue driving mechanism 300 is used to drive the locking tongue 200 to move to the unlocking position when being initially triggered, and the locking tongue 200 remains in the unlocking position before the locking tongue driving mechanism 300 is triggered for the second time. The locking tongue driving mechanism 300 can be automatically triggered for the second time during the process of detaching the medical module from the medical host or when the medical module is reinstalled on the medical host after being detached, so as to drive the locking tongue 200 to move from the unlocking position to the locking position.

[0111] When the staff needs to detach the medical module from the medical host, the locking tongue driving mechanism 300 can be triggered once first. The locking tongue driving mechanism 300 drives the locking tongue 200 to move from the locking position to the unlocking position, and the locking tongue 200 will remain stationary in the unlocking position, so that the staff can use both hands to detach the medical module from the medical host. When the staff completes the disinfection or maintenance work on the anesthesia machine, the medical module can be reinstalled on the medical host. At this time, the locking tongue driving mechanism 300 will be automatically triggered for the second time, so that the locking tongue driving mechanism 300 drives the locking tongue 200 to move from the unlocking position to the locking position, thereby realizing the automatic locking of the medical module and the medical host. On the one hand, since the locking tongue driving mechanism 300 can drive the locking tongue 200 to remain in the unlocking position after being initially triggered, it enables the staff to use both hands to perform the disassembly work of the medical module, which is beneficial to reducing the difficulty of the disassembly work. On the other hand, after the medical module is reinstalled on the medical host, it can be automatically locked to the medical host, thus avoiding the risk that the staff forgets to lock the medical module to the medical host. Or, during the process of the staff detaching the medical module from the medical host, the locking tongue driving mechanism 300 will be automatically triggered for the second time, so that the locking tongue driving mechanism 300 drives the locking tongue 200 to move from the unlocking position to the locking position, thereby preparing for the staff to reinstall the medical module subsequently.
