Abstract
Description
Technical Field
[0001] This application relates to the field of anesthesia machine technology, specifically to an interlocking mechanism and an anesthesia machine. Background Technology
[0002] The "interlocking pin" structure on an anesthesia machine is a safety mechanism designed to prevent operational errors during anesthesia and ensure the correct and safe use of the equipment. Interlocking pins are typically designed to connect different mechanical components or control links. The main principle of the "interlocking pin" structure is to ensure that only one anesthetic solution from one vaporizer is used during anesthesia machine operation, preventing accidental delivery of different solutions to the patient's airway due to misoperation or vaporizer malfunction, thus achieving safe output. The "interlocking pin" relies heavily on direct mechanical operation, mostly through manual rotation of a knob. The knob extends and retracts the interlocking pin via a mechanical linkage mechanism. Because it depends on a purely mechanical mechanism, it suffers from slow response time, poor user experience, and low control precision. Utility Model Content
[0003] This application provides an interlocking mechanism and an anesthesia machine, which can solve the problems of interlocking mechanisms relying on manual operation, slow response speed, poor user experience, and low control precision.
[0004] To address the aforementioned technical problems, this application provides an interlocking mechanism applied to an evaporator. The interlocking mechanism includes an electric component, a contact member, and a resilient interlocking component. The electric component includes a power member, which, when energized, enables movement; the power member drives the contact member to reciprocate; the resilient interlocking component is slidably connected to the evaporator; the resilient interlocking component has an interlocked position and an unlocked position, and the movement of the contact member drives the resilient interlocking component from the unlocked position to the interlocked position; the elastic restoring force of the resilient interlocking component resets the resilient interlocking component from the interlocked position to the unlocked position.
[0005] In one embodiment, the electric component is an electromagnet component, a pneumatic component, or a hydraulic component; the electromagnet component can generate a magnetic field when energized, and the power component can move when the magnetic field changes; the pneumatic component can drive the power component to move by compressing or releasing gas volume; the hydraulic component can drive the power component to move by a hydraulic pump.
[0006] In one embodiment, the electric component further includes an electromagnet and a first elastic element. One end of the first elastic element is used to abut against a contact element. When the electromagnet is energized, it can generate a magnetic field. The magnetic force of the magnetic field is used to attract or repel the power element. When the magnetic force of the magnetic field is greater than the elastic force of the first elastic element, the power element moves along a first direction to move the elastic interlock component from the unlocked position to the interlocked position. When the magnetic force is less than or equal to the elastic force of the first elastic element, or when the electromagnet is de-energized, the power element moves in the opposite direction of the first direction to move the elastic interlock component from the interlocked position to the unlocked position.
[0007] In one embodiment, the power member and the abutment member are fixedly connected, and the power member and the abutment member move synchronously. The movement direction of the abutment member is consistent with the movement direction of the power member. The elastic interlocking assembly can reciprocate along the second direction or the opposite direction of the second direction. The first direction is perpendicular to the second direction.
[0008] In one embodiment, the end of the abutment member near the elastic interlocking assembly has a ramp, the side of the ramp facing the elastic interlocking assembly is an inclined surface, the height of the inclined surface decreases along the first direction, the direction of the elastic restoring force of the elastic interlocking assembly is along the second direction, and the elastic interlocking assembly remains abutting the inclined surface under the action of the elastic restoring force of the elastic interlocking assembly.
[0009] In one embodiment, the power element and the electromagnet are arranged sequentially along a first direction, one end of the first elastic element is connected to the electromagnet, the other end of the first elastic element is used to abut against the power element, and the magnetic force of the magnetic field is used to attract the power element.
[0010] In one embodiment, the electromagnet is provided with a guide channel, and at least a portion of the power member is slidably disposed within the guide channel. The guide channel extends along a first direction to limit the power member in a direction perpendicular to the first direction.
[0011] In one embodiment, the elastic interlock assembly includes a fixing member, a second elastic member, and an interlocking pin. The fixing member is used to fix it to the evaporator, the interlocking pin is slidably connected to the fixing member, and the interlocking pin abuts against a stop member. One end of the second elastic member is fixed to the fixing member, and the other end of the second elastic member is used to abut against the interlocking pin. The elastic restoring force of the second elastic member is used to reset the interlocking pin.
[0012] In one embodiment, there are two elastic interlocking components, and an abutment can be disposed between the two elastic interlocking components so that the two elastic interlocking components abut against opposite sides of the abutment, and the movement of the abutment can drive the two elastic interlocking components to move toward the interlocking position in opposite directions.
[0013] To solve the above-mentioned technical problems, this application provides an anesthesia machine, which includes a vaporizer and an interlocking mechanism according to any of the above embodiments. The number of vaporizers is two, and the interlocking mechanism is installed on the vaporizers. The elastic interlocking components of the two vaporizers are arranged opposite to each other. When the elastic interlocking component of one of the two vaporizers is in the interlocked position, the elastic interlocking component in the interlocked position can limit the elastic interlocking component of the other vaporizer, so that the other vaporizer cannot work.

When energized, the electric component enables movement of the power component. The power component, through the contact member, drives the resilient interlocking component to switch between the interlocked and unlocked positions. By controlling the interlocking mechanism through the power component, the power component can have a high response speed under the influence of electricity, providing a better user experience. Furthermore, the control precision of the power component's movement is higher when controlled by electricity. Attached Figure Description

Therefore, they should not be construed as limitations on the embodiments of this application.
[0027] Please refer to Figure 1 and Figure 2 This application provides an anesthesia machine 10, which includes a vaporizer 20 and an interlocking mechanism 30. The interlocking mechanism 30 may have the same or similar structure as the interlocking mechanism 30 in any of the embodiments described below, and perform the same or similar functions. There are two vaporizers 20, and the interlocking mechanism 30 is installed on each vaporizer 20, that is, each vaporizer 20 is equipped with a set of interlocking mechanisms 30.
[0028] like Figure 3-7 As shown, this application provides an interlocking mechanism 30, which can be applied to the aforementioned evaporator 20. The interlocking mechanism 30 includes an electric component 31, an abutment member 32, and a resilient interlocking component 33.
[0029] Specifically, such as Figure 1-3 After the two vaporizers 20 are installed on the anesthesia machine 10, their elastic interlocking components 33 are arranged opposite each other. Preferably, the elastic interlocking components 33 of the two vaporizers 20 are arranged opposite each other along a straight line. Each elastic interlocking component 33 has an interlocked position and an unlocked position, and each elastic interlocking component 33 can switch between the interlocked position and the unlocked position. When the elastic interlocking component 33 of one of the two vaporizers 20 is in the interlocked position, the elastic interlocking component 33 in the interlocked position can limit the elastic interlocking component 33 of the other vaporizer 20, so that the other vaporizer 20 cannot work. A sensor can be installed on the interlocking mechanism 30 of the vaporizer 20. The sensor can sense whether the elastic interlocking component 33 has reached the interlocked position. When the sensor does not sense that the elastic interlocking component 33 has reached the interlocked position, the vaporizer 20 will not work.
[0030] Specifically, the interlocked position is closer to the other evaporator 20 than the unlocked position; that is, the elastic interlock component 33 in the interlocked position extends further out of the evaporator 20 than the elastic interlock component 33 in the unlocked position. This can be achieved by the elastic interlock component 33 in one interlocked position occupying the interlocked position of the elastic interlock component 33 of the other evaporator 20, preventing the other evaporator 20's elastic interlock component 33 from reaching its interlocked position, or by the elastic interlock component 33 in one interlocked position abutting against the elastic interlock component 33 of the other evaporator 20, preventing the other evaporator 20's elastic interlock component 33 from moving. For example, in... Figure 2 In this embodiment, the elastic interlock component 33 of the right evaporator 20 extends, and the right evaporator 20 is in the working state. The left evaporator 20 is limited by the elastic interlock component 33 of the right evaporator 20 and cannot extend, so the left evaporator 20 is in the stopped working state.
[0031] When the elastic interlock assembly 33 of one of the two vaporizers 20 is in the interlocked position, the elastic interlock assembly 33 of the other vaporizer 20 cannot extend to the interlocked position. Therefore, the anesthetic solution in only one vaporizer 20 can be used during the operation of the anesthesia machine 10, preventing accidental delivery of the anesthetic solution in both vaporizers 20 to the patient's airway at the same time.
[0032] like Figure 3-7 As shown, the electric component 31 includes a power element 311, which, when energized, enables movement. For example, when an operator performs an initialization operation via the control panel buttons, the system provides an energizing signal to the power element 311, energizing it. The electric component 31 is used to control the elastic interlock component 33 to switch between the interlocked and unlocked positions. The electric component 31 can convert electrical energy into the kinetic energy of the power element 311.
[0033] For example, in one embodiment, the electric component 31 is an electromagnet 312 assembly, a pneumatic assembly, or a hydraulic assembly. The electromagnet 312 assembly can generate a magnetic field when energized, and the power component 311 can move when the magnetic field changes. Specifically, the electromagnet 312 generates a magnetic field by passing current through a coil, thereby attracting or repelling ferromagnetic objects. The pneumatic assembly can drive the power component 311 by compressing or releasing gas volume; for example, the pneumatic assembly can use compressed air as the working medium and control mechanical movement through cylinders and valves. The hydraulic assembly can drive the power component 311 by a hydraulic pump; for example, the hydraulic assembly can use hydraulic oil as the working medium and transmit power and movement through a hydraulic pump and hydraulic cylinder.
[0034] Please refer to Figure 3-7 ,in, Figure 3 The elastic interlock component 33 is located in the interlock position. Figure 5 The elastic interlock component 33 is in the unlocked position. The power component 311 can drive the abutment component 32 to reciprocate. The elastic interlock component 33 can be slidably connected to the evaporator 20. The movement of the abutment component 32 can drive the elastic interlock component 33 from the unlocked position to the interlocked position. That is, by energizing the electric component 31, the power component 311 and the abutment component 32 move, so that the elastic interlock component 33 moves from the unlocked position to the interlocked position. When the force of the abutment component 32 on the elastic interlock component 33 disappears, the elastic restoring force of the elastic interlock component 33 can reset the elastic interlock component 33 from the interlocked position to the unlocked position.
[0035] The interlocking mechanism 30 of this application is powered by an electric component 31. When the electric component 31 is energized, it can move the power component 311. The power component 311 can drive the elastic interlocking component 33 to switch between the interlocked position and the unlocked position through the abutment component 32. The interlocking of the interlocking mechanism 30 is controlled by the power component 311. The power component 311 can have a high response speed under the action of electricity, which brings a better user experience. Moreover, the control precision of the movement of the power component 311 controlled by electricity is higher and it is less prone to errors.
[0036] like Figure 3-7As shown, in one embodiment, the electric component 31 further includes an electromagnet 312 and a first elastic member 313. One end of the first elastic member 313 is used to abut against the abutment member 32, and the other end of the first elastic member 313 is fixedly disposed relative to the evaporator 20. The electromagnet 312 generates a magnetic field when energized, and the magnetic force of the magnetic field is used to attract or repel the power member 311. When the power member 311 moves under the action of the magnetic force, the first elastic member 313 generates an elastic force in the opposite direction to the magnetic force. When the magnetic force of the magnetic field is greater than the elastic force of the first elastic member 313, the power member 311 moves along a first direction X. The first direction X can be towards the electromagnet 312 or away from the electromagnet 312. The first direction X is related to whether the magnetic force attracts or repels the power member 311. When the magnetic force attracts the power member 311, the first direction X is towards the electromagnet 312; when the magnetic force repels the power member 311, the first direction X is away from the electromagnet 312. When the power component 311 moves along the first direction X, it can move the elastic interlock assembly 33 from the unlocked position to the interlocked position. When the magnetic field force is less than or equal to the elastic force of the first elastic component 313, or when the electromagnet 312 is de-energized, the power component 311 moves in the opposite direction of the first direction X under the action of the elastic force of the first elastic component 313, so that the elastic interlock assembly 33 moves from the interlocked position to the unlocked position. The first elastic component 313 can be a spring, a sheet, etc. When the power component 311 moves under the action of the magnetic field force, the spring can be compressed to generate an elastic force. By setting the first elastic component 313, the elastic interlock assembly 33 can be automatically reset when the electromagnet 312 is de-energized.
[0037] In one embodiment, the power member 311 is fixedly connected to the abutment member 32, and the power member 311 and the abutment member 32 move synchronously so that the movement direction of the abutment member 32 is consistent with the movement direction of the power member 311. For example, when the power member 311 moves along the first direction X, the abutment member 32 also moves along the first direction X; when the power member 311 moves in the opposite direction of the first direction X, the abutment member 32 also moves synchronously in the opposite direction of the first direction X. When the abutment member 32 moves along the first direction X, the elastic interlocking assembly 33 can move along the second direction Y; when the abutment member 32 moves in the opposite direction of the first direction X, the elastic interlocking assembly 33 can reciprocate in the opposite direction of the second direction Y. The first direction X and the second direction Y are perpendicular. Through the movement of the abutment member 32, the movement along the direction of the magnetic force can be converted into movement perpendicular to the direction of the magnetic force, which facilitates the installation and arrangement of the evaporator 20.
[0038] Specifically, the end of the abutment 32 near the elastic interlock assembly 33 has a ramp 321. The side of the ramp 321 facing the elastic interlock assembly 33 is an inclined surface. The height of the inclined surface decreases along the first direction X. The direction of the elastic restoring force of the elastic interlock assembly 33 is along the second direction Y. Under the action of the elastic restoring force, the elastic interlock assembly 33 remains abutting the inclined surface. Thus, when the abutment 32 moves along the first direction X, the ramp 321 also moves along the first direction X. Since the height of the inclined surface along the first direction X decreases, the ramp 321 pushes the elastic interlock assembly 33 to slide along the inclined surface towards the position where the height of the ramp 321 decreases, so that the elastic interlock assembly 33 is pushed out, thereby moving the elastic interlock assembly 33 from the unlocked position to the interlocked position. When the abutment 32 moves in the opposite direction of the first direction X, the ramp 321 also moves in the opposite direction of the first direction X. As the height of the ramp increases in the opposite direction of the first direction X, the elastic interlock assembly 33 moves toward the ramp under the action of the elastic restoring force of the elastic interlock assembly 33, so that the elastic interlock assembly 33 is reset.
[0039] In one embodiment, at least a portion of the power member 311 and the electromagnet 312 are arranged sequentially along a first direction X. One end of the first elastic member 313 is connected to the electromagnet 312, and the other end of the first elastic member 313 is used to abut against the power member 311. The magnetic force of the magnetic field is used to attract the power member 311. When the electromagnet 312 is energized, the magnetic force of the magnetic field attracts the power member 311, causing the power member 311 to move towards the first direction X, and causing the first elastic member 313 to generate an elastic restoring force. Since the magnetic force is greater than the elastic restoring force of the first elastic member 313, the power member 311 continues to move towards the first direction X, and drives the abutment member 32 to move towards the first direction X. The ramp 321 on the abutment member 32 can push the abutment member 32 out, causing the elastic interlock assembly 33 to move towards the second direction Y, so that the elastic interlock assembly 33 moves from the unlocked position to the interlocked position. When the electromagnet 312 is de-energized, the power component 311 will move in the opposite direction of the first direction X under the action of the first elastic component 313, and drive the abutment component 32 to move in the opposite direction of the first direction X. Under the action of the elastic restoring force of the elastic interlock component 33, the elastic interlock component 33 moves in the opposite direction of the second direction Y, so that the elastic interlock component 33 moves from the interlock position to the unlock position.
[0040] In one embodiment, such as Figure 4 and Figure 6As shown, a guide channel 3121 is provided inside the electromagnet 312, and at least a portion of the power member 311 is slidably disposed within the guide channel 3121. The guide channel 3121 extends along the first direction X to limit the movement of the power member 311 in a direction perpendicular to the first direction X. By placing the power member 311 within the guide channel 3121 of the electromagnet 312, the movement of the power member 311 in the first direction X or the opposite direction of the first direction X can be made more stable, thereby improving the reliability of the interlocking mechanism 30.
[0041] In one embodiment, the elastic interlock assembly 33 includes a fixing member 331, a second elastic member 332, and an interlocking pin 333. The fixing member 331 is used to fix it to the evaporator 20, and the interlocking pin 333 is slidably connected to the fixing member 331. For example, the fixing member 331 can be a ring-shaped structure, and the interlocking pin 333 passes through the ring-shaped fixing member 331. The interlocking pin 333 abuts against the inclined surface of the abutment member 32. One end of the second elastic member 332 is fixed to the fixing member 331, and the other end of the second elastic member 332 is used to abut against the interlocking pin 333. The elastic restoring force of the second elastic member 332 is used to reset the interlocking pin 333. In other embodiments, a slide rail can be directly provided on the evaporator 20, and the interlocking pin 333 can be slidably disposed in the slide rail, with the second elastic member 332 directly fixed to the evaporator 20. Thus, the fixing member 331 can be omitted.
[0042] In one embodiment, there are two elastic interlocking components 33. An abutment 32 is disposed between the two elastic interlocking components 33, such that the two elastic interlocking components 33 abut against opposite sides of the abutment 32. Both opposite sides of the abutment 32 are provided with ramps 321. Movement of the abutment 32 can drive the two elastic interlocking components 33 to move towards the interlocking position in opposite directions. Therefore, even after the two vaporizers 20 exchange positions, the function of the elastic interlocking components 33 can still be achieved. Thus, compared to the scheme of only one elastic interlocking component 33 on one vaporizer 20, when installing the vaporizer 20 on the anesthesia machine 10, the user does not need to pay extra attention to the position of the elastic interlocking components 33, nor does the user need to install the two vaporizers 20 in sequence. Even if the positions of the two vaporizers 20 are exchanged, they can still have an interlocking function to avoid operator errors.
[0043] The above examples illustrate this application only to aid in understanding the invention and are not intended to limit the scope of the application. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the concept of this application.
