Description

Technical Field

[0001] The present invention relates to the technical field of anesthesia systems, and in particular to a breathing circuit lifting device and an anesthesia machine. Background Art

[0002] An anesthetic breathing circuit forms a loop between the anesthesia machine's gas outlet and the patient's airway. Fresh air and inhaled anesthetics are delivered to the patient's airway through the circuit, while carbon dioxide in the patient's exhaled air is filtered through an absorbent and re-enters the respiratory circulation. Excess gas is discharged to the waste gas treatment system. The circuit integrates an inspiratory and expiratory flow sensor, an oxygen battery, a manual-automatic switching valve (BTV), a pressure limiting valve (APL), a sensor heating module, an airway pressure sampling port, and a fresh air inlet. Because the circuit requires regular cleaning and disinfection, it must be easily disassembled. Because the circuit has numerous interfaces between the anesthesia breathing circuit and the anesthesia machine, including those for drive air, fresh air, waste gas, airway pressure, differential pressure sensor, electrical heating, and oxygen battery, the reliability of each interface must be ensured after installation.

[0003] In the prior art, anesthesia breathing circuits usually adopt a lateral disassembly structure or a rotational disassembly structure. For the lateral disassembly structure, two guide columns and a locking mechanism are usually required, and all interfaces are concentrated on the side of the main unit of the anesthesia machine. This structural layout is limited, and the gas circuit interface and electrical interface are concentrated, which poses the risk of leakage and poor contact. In addition, the guide column will take up a certain amount of space, which is not conducive to compact structural optimization. For the rotational disassembly structure, although the layout has greater flexibility, all interfaces will be pulled and slipped during the installation process, which will greatly increase the risk of leakage and poor contact, and easily cause gas circuit leakage and poor electrical contact.

[0004] Therefore, how to optimize the structural layout of the breathing circuit to facilitate disassembly and installation is a technical problem that those skilled in the art currently need to solve. Summary of the Invention

[0062] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any novel efforts shall fall within the scope of protection of the present invention.

[0063] In the description of the present invention, it should be understood that the terms "upper," "lower," "top," and "bottom" and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the positions or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations of the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0064] like Figure 1 As shown, this is a schematic diagram of the rotating disassembly structure in the prior art. The interface between the anesthesia machine and the breathing circuit body 100 will be pulled and slipped during the installation process, which greatly increases the risk of leakage and poor contact, and is prone to gas leakage and poor electrical contact.

[0065] like Figure 2As shown, the breathing circuit lifting device disclosed in the present invention is arranged on an anesthesia machine, and includes a lifting mechanism, a breathing circuit body 100, and an unlocking mechanism, wherein the lifting mechanism is arranged on the anesthesia machine and is used to lift and lower the breathing circuit body 100 in the vertical direction, the breathing circuit body 100 is detachably connected to the lifting mechanism, and the unlocking mechanism is connected to the lifting mechanism. When the unlocking mechanism is in a locked state, the lifting mechanism is in a lifting state, and when the unlocking mechanism is in an unlocked state, the lifting mechanism is in a lowering state. Specifically, the lifting mechanism is connected to the anesthesia machine and can move in the vertical direction of the anesthesia machine, but during the lifting or lowering process, the lifting mechanism is not separated from the anesthesia machine, and when the breathing circuit body 100 needs to be installed on or removed from the lifting mechanism, the lifting mechanism and the unlocking mechanism do not need to be separated from the anesthesia machine. Therefore, such an arrangement can make the structural layout of the breathing circuit lifting device on the anesthesia machine very reasonable. Initially, the unlocking mechanism is in the unlocked state and the lifting mechanism is in the lowered state. After the breathing circuit body 100 is connected to the lifting mechanism, the unlocking mechanism switches from the unlocked state to the locked state, while simultaneously driving the lifting mechanism to rise vertically until the breathing circuit body 100 is connected to the anesthesia machine. At this point, the unlocking mechanism is in the locked state and the lifting mechanism is in the raised state. This arrangement allows the interface on the breathing circuit body 100 to connect vertically to the anesthesia machine, avoiding poor contact. Furthermore, when the breathing circuit body 100 needs to be disassembled, there is no need to disassemble the lifting mechanism and unlocking mechanism, making the overall structure more reasonable and compact. This optimizes the breathing circuit structural layout, making it easier to disassemble and install.

[0066] like Figure 3-Figure 5As shown, in some embodiments of the present invention, the lifting mechanism includes a base connecting plate 200, a lifting cam 201 and a roller 202, wherein the base connecting plate 200 includes a first plate 2001 and a second plate 2002, the first plate 2001 and the second plate 2002 are arranged vertically, the first plate 2001 is used to connect the breathing circuit body 100, the second plate 2002 moves in the vertical direction along the anesthesia machine, the lifting cam 201 is provided with a lifting groove 2011 on one side close to the second plate 2002, the roller 202 is arranged inside the lifting groove 2011, and moves along the opening track of the lifting groove 2011, and the roller 202 is moved along the opening track of the roller 202. The second plate 2002 is connected, the first end of the lifting groove 2011 is located at the bottom of the lifting cam 201, and the second end is located at the top of the lifting cam 201. The unlocking mechanism is connected to the lifting cam 201. When the unlocking mechanism switches from the locked state to the unlocked state, the unlocking mechanism controls the lifting cam 201 to move in the first direction, and the roller 202 moves from the second end of the lifting groove 2011 to the first end of the lifting groove 2011. When the unlocking mechanism switches from the unlocked state to the locked state, the unlocking mechanism controls the lifting cam 201 to move in the second direction, and the roller 202 moves from the first end of the lifting groove 2011 to the second end of the lifting groove 2011. Specifically, the lifting groove 2011 is arc-shaped, with its first and second ends respectively located at the two ends of a diagonal line of the lifting cam 201. The arc-shaped lifting groove 2011 can make the lifting cam 201 more evenly stressed. Lifting groove 2011 with other shapes is also within the scope of protection of the present invention and will not be described in detail here. Specifically, the roller 202 is rotatably connected to the second plate 2002 and can drive the second plate 2002 to move. Specifically, the solution of the roller 202 being fixedly connected to the second plate 2002 is also within the scope of protection of the present invention and will not be described in detail here.

[0067] Furthermore, when in use, the anesthesia machine is connected to a carbon dioxide absorption tank 400 , and an opening for connecting the carbon dioxide absorption tank 400 is provided on the first plate 2001 . The carbon dioxide absorption tank 400 is connected to the anesthesia machine from the bottom of the first plate 2001 upwards.

[0068] During use, when the unlocking mechanism switches from a locked state to an unlocked state, the unlocking mechanism controls the lifting cam 201 to move in a first direction, and the roller 202 moves from the second end of the lifting groove 2011 to the first end of the lifting groove 2011. At the same time, the base connecting plate 200 descends in a vertical direction. After descending into place, the operator can remove or install the breathing circuit body 100 to the first plate 2001. When the unlocking mechanism switches from an unlocked state to a locked state, the unlocking mechanism controls the lifting cam 201 to move in a second direction, and the roller 202 moves from the first end of the lifting groove 2011 to the second end of the lifting groove 2011. At the same time, the base connecting plate 200 is lifted in a vertical direction. After lifting into place, the unlocking mechanism is in a locked state. It should be noted that the first direction and the second direction are two opposite directions along the horizontal direction. Such an arrangement can convert the horizontal movement of the lifting cam 201 into the vertical movement of the base connecting plate 200, has a compact structure, and optimizes the structural layout of the breathing circuit.

[0069] To optimize the above technical solution, the lifting mechanism also includes a lifting guide rail 203. The first side of the lifting guide rail 203 cooperates with the second plate 2002, and the lifting cam 201 moves horizontally along the second side adjacent to the lifting guide rail 203. Specifically, guide grooves are defined on both sides of the lifting guide rail 203. These grooves respectively cooperate with the two sides of the second plate 2002, so that when the second plate 2002 moves vertically, the two sides of the second plate 2002 engage within the guide grooves. Specifically, when the unlocking mechanism is in the locked state, the second plate 2002, the lifting guide rail 203, and the lifting cam 201 are arranged in sequence in a direction perpendicular to the second plate 2002. By arranging the lifting guide rail 203, the second plate 2002 can move vertically along a fixed trajectory, preventing it from deflecting, thereby improving the lifting and lowering efficiency of the lifting mechanism.

[0070] In order to optimize the above technical solution, the lifting mechanism also includes a slide rail 204, which is arranged at the top and / or bottom of the lifting cam 201 to move the lifting cam 201 in the horizontal direction. Specifically, because the lifting cam 201 needs to move in the horizontal direction during the process of switching from unlocking to locking or from locking to unlocking, the slide rail 204 is arranged at the top and / or bottom of the lifting cam 201 to reduce the wear of the lifting cam 201 on the anesthesia machine. Furthermore, a plurality of guide rods 205 are fixed on the anesthesia machine, so that the lifting cam 201 can only move within the horizontal range enclosed by the plurality of guide rods 205, which is also within the scope of protection of the present invention and will not be repeated here. Furthermore, the guide rods 205 and the slide rail 204 can be arranged at the same time to make the movement of the lifting cam 201 more convenient.

[0071] During use, the lifting cam 201 moves along the slide rail to drive the base connecting plate 200 to rise or fall. This arrangement can utilize a small space to reduce the wear and tear caused by the movement of the lifting cam 201 on the anesthesia machine, while standardizing the movement trajectory of the lifting cam 201 and further optimizing the breathing circuit structure layout.

[0072] To optimize the above technical solution, the breathing circuit lifting device further includes a counterweight mechanism 300, which is arranged opposite the second end of the lifting groove 2011 and connected to the second plate 2002, and is used to match the weight of the breathing circuit body 100. Specifically, the counterweight mechanism 300 includes, but is not limited to, a counterweight coil spring, a counterweight block, etc., as long as it can match the weight of the breathing circuit body 100. When the counterweight mechanism 300 is a counterweight coil spring, when in use, when the base connecting plate 200 is lowered, the second plate 2002 pulls up the counterweight coil spring to prevent the breathing circuit body 100 from falling when the base connecting plate 200 is lowered. When the base connecting plate 200 is raised, the counterweight coil spring retracts, returning to its original state.

[0073] Furthermore, the counterweight coil spring can be optimized as a constant-force coil spring, whose force acting on the second plate 2002 is constant and equal to the weight of the breathing circuit body 100. This ensures that the force on the base connecting plate 200 is balanced during the lowering or lifting of the breathing circuit body 100, thereby improving the operational stability of the breathing circuit lifting device. Therefore, by arranging the counterweight mechanism 300, the weight of the breathing circuit body 100 can be matched, preventing the breathing circuit body 100 from falling, and improving the operational stability of the breathing circuit lifting device.

[0074] like Figure 6 and Figure 7 As shown, to optimize the above technical solution, the breathing circuit lifting device also includes a breathing circuit mounting base 500. The bottom of the breathing circuit mounting base 500 is connected to the first plate 2001, and its top is used to connect the breathing circuit body 100. The breathing circuit mounting base 500 is used to connect the breathing circuit body 100 to the anesthesia machine. Specifically, the breathing circuit body 100 and the carbon dioxide absorber 400 are both connected to the anesthesia machine via the breathing circuit mounting base 500. During use, the breathing circuit mounting base 500 is connected to the first plate 2001, and the breathing circuit body 100 is installed on the breathing circuit mounting base 500. The base connecting plate 200 drives the breathing circuit mounting base 500 and the breathing circuit body 100 to rise vertically until the interface of the breathing circuit body 100 connects with the interface of the anesthesia machine, thereby locking the unlocking mechanism. This arrangement ensures that the interface of the breathing circuit body 100 is vertically connected to the interface of the anesthesia machine, optimizing the structural layout of the breathing circuit while ensuring the reliability of each interface after the breathing circuit body 100 is installed in the anesthesia machine.

[0075] like Figures 8-10 As shown, to optimize the above technical solution, the unlocking mechanism includes a safety reset member 600, an unlocking handle 601, a safety 602, and a connecting rod 603. The unlocking handle 601 and the safety 602 are arranged parallel to each other. The safety reset member 600 is arranged between the unlocking handle 601 and the safety 602. The safety 602 is provided with a rotating shaft for cooperating with the connecting rod 603. The first end of the connecting rod 603 is connected to the lifting cam 201. The second end of the connecting rod 603 is rotatably provided with a clamping member 604. The rotating shaft cooperates with the clamping member 604. When the unlocking mechanism is in the locked state, the rotating shaft engages with the first clamping slot 6041 of the clamping member 604. When the unlocking mechanism is in the unlocked state, the rotating shaft engages with the second clamping slot 6042 of the clamping member 604. Specifically, the safety reset member 600 includes but is not limited to components such as a spring and a push button. Specifically, the safety reset member 600 is arranged at the second end of the safety 602.

[0076] During use, when the unlocking mechanism needs to be switched from a locked state to an unlocked state, the operator presses the first end of the safety 602 to move the first end of the safety 602 in a direction close to the unlocking handle 601, and the rotating shaft disengages from the first slot 6041. At the same time, the unlocking handle 601 is rotated along the third direction. When the unlocking handle 601 is rotated to the preset position of the fully unlocked state, the rotating shaft is engaged in the second slot 6042, and the safety reset member 600 resets the safety and controls the rotating shaft to continue to be engaged in the second slot 6042. During the rotation of the unlocking handle, the connecting rod 603 is driven to move horizontally along the first direction, and the connecting rod 603 drives the lifting cam 201 to move along the first direction. The lifting cam 201 drives the base connecting plate 200 to descend, so that the breathing circuit body 100 can be installed and disassembled.

[0077] During use, when the unlocking mechanism needs to be switched from the unlocked state to the locked state, the operator presses the first end of the safety 602, causing the first end of the safety 602 to move in a direction close to the unlocking handle 601, disengaging the rotating shaft from the second engaging slot 6042, and simultaneously rotating the unlocking handle 601 in the fourth direction. When the unlocking handle 601 is rotated to the preset position of the fully locked state, the rotating shaft engages with the first engaging slot 6041, and the safety reset member 600 resets the safety and controls the rotating shaft to remain engaged with the first engaging slot 6041. During the rotation of the unlocking handle, the connecting rod 603 is driven to move horizontally in the second direction, and the connecting rod 603 drives the lifting cam 201 to move in the second direction, which in turn drives the base connecting plate 200 to lift. It should be noted that, depending on the location of the unlocking mechanism, the third direction is clockwise and the fourth direction is counterclockwise, or the third direction is counterclockwise and the fourth direction is clockwise.

[0078] like Figure 11 and Figure 12 As shown, in other embodiments of the present invention, the lifting mechanism includes a base connecting plate 200 and a connecting rod structure, which includes multiple connecting rods. The first end of the connecting rod structure is connected to the unlocking mechanism, and the second end of the connecting rod structure is connected to the base connecting plate 200. This arrangement only requires installing multiple connecting rods to connect the unlocking mechanism to the base connecting plate 200, which simplifies the structure and facilitates replacement and maintenance.

[0079] like Figure 13 As shown, in some other embodiments of the present invention, the lifting mechanism includes a base connecting plate 200 and a drive motor 700, which is used to drive the base connecting plate 200 to move vertically. This arrangement allows the base connecting plate 200 to be directly controlled to move linearly by the drive motor 700, resulting in a simple structure and easy installation.

[0080] like Figure 14-17 As shown, the present invention also discloses an anesthesia machine, including an anesthesia machine body 800 and an interface interface 900, and also includes a breathing circuit lifting device as any of the above items, the interface interface 900 is arranged relative to the breathing circuit body 100, and when the unlocking mechanism is in a locked state, the interface interface 900 is connected to the breathing circuit body 100.
