Description

Technical Field

[0001] This invention relates to the field of anesthesia equipment technology, and more specifically, to a multifunctional anesthesia machine and system. Background Technology

[0002] Currently, before anesthesia surgery, the parameters of the anesthesia machine need to be adjusted according to the needs of the surgery. After the adjustment is completed, the circuit system supplies anesthetic gas and oxygen. Generally, the supply and recovery are achieved through an inlet tube and a return tube. The inlet tube and the return tube are connected to the gas supply line through a Y-type connector to provide breathing for the surgical patient.

[0003] During surgical procedures, controlling the position of the inhalation tube is particularly important, especially regarding the stability of its connection with the inhalation mask. Typically, a specialist is assigned to fix the inhalation tube and connector, either manually or with clamps. The former is more labor-intensive, while the latter, although it solves the problem of high labor intensity, has the drawback of inconvenient adjustment.

[0004] In the existing technology, we understand that there are methods that use purely mechanical articulated hands to clamp the gas delivery pipe. Although this has the advantage of certain position adjustment, it only has a clamping function. It cannot fully guarantee that it can be clamped securely without affecting the gas delivery of the gas delivery pipe. In particular, the clamping direction after clamping cannot be well controlled, which affects the connection stability between the gas delivery pipe and the gas delivery cover and is prone to falling off.

[0005] In view of the above, this application is hereby submitted. Summary of the Invention

[0006] The purpose of this invention is to provide a multifunctional anesthesia machine and system. This anesthesia machine and system can not only clamp the gas delivery tube and Y-connector to ensure the clamping stability of the entire gas supply system, but also adjust the clamping direction and perform fine-tuning by pulling and retracting, thereby ensuring the ease of operation of the entire clamping and further improving the clamping stability.

[0007] The embodiments of the present invention are implemented as follows:

[0008] In a first aspect, a multifunctional anesthesia machine includes an anesthesia machine body, an adjustment mechanism, and a clamping mechanism. The anesthesia machine body has a circuit system, which includes a first air port and a second air port. Both the first and second air ports are used to connect to anesthesia delivery tubes, and the two anesthesia delivery tubes converge through a Y-connector. The adjustment mechanism includes a fixed base and a parallel swing assembly. The fixed base is connected to the anesthesia machine body and is hinged to a first free end of the parallel swing assembly. A swing adjustment component, driven and connected to a second free end of the parallel swing assembly, is mounted on the fixed base to allow the third free end of the parallel swing assembly to move away from or towards the fixed base. The clamping mechanism includes a telescopic component, a first clamping component, and a second clamping component. The telescopic component is connected to the third free end. The first clamping component is slidably connected to the telescopic end of the telescopic component and is used to clamp the anesthesia inlet tube. The second clamping component is oscillatingly connected to the telescopic end of the telescopic component and is used to clamp the Y-shaped connector. A position adjustment component is provided on the fixed base. The position adjustment component acts on the fourth free end of the parallel swing component, allowing the third free end to bounce away from or towards the fixed base, so that the first clamping component and the second clamping component respectively pull and retract the anesthesia inlet tube and the Y-shaped connector.

[0009] In an optional embodiment, the parallel swing assembly includes a first swing arm and a second swing arm, with two parallel telescopic rods hinged between the first swing arm and the second swing arm. The two ends of the first swing arm form the first free end and the second free end, respectively, and the two ends of the second swing arm form the third free end and the fourth free end, respectively.

[0010] In an alternative embodiment, the third free end is located below the fourth free end during use.

[0011] In an optional embodiment, the adjusting assembly includes an adjusting rod and a threaded sleeve, the threaded sleeve being rotatably connected to the fixed base, one end of the adjusting rod passing through the threaded sleeve and being rotatably connected to the second free end, and the adjusting rod being threadedly engaged with the threaded sleeve.

[0012] In an optional embodiment, the position adjustment component includes a servo motor and a traction belt. The servo motor is mounted on the fixed base, a first end of the traction belt is driven and connected to the servo motor, and a second end of the traction belt is wound around the fourth free end and fixedly connected to the third free end.

[0013] In an optional embodiment, the position adjustment assembly further includes a roller assembly comprising a first roller, a second roller, and a third roller. The first roller is rotatably disposed on the fixed base and is used to wind around a first end of the traction belt. The second roller is rotatably disposed on the fourth free end and is used to wind around the middle portion of the traction belt. The third roller is rotatably disposed on the third free end and is used to wind around a second end of the traction belt.

[0014] In an optional embodiment, the two ends of the axle of the third roller are respectively rotatably connected to the third free end, and damping pads are provided at the rotatable connection points; a tightening belt is connected between the axle and the fixed end of the telescopic component, the tightening belt is used to adjust the distance between the fixed end of the telescopic component and the third free end, and the tightening direction of the tightening belt is consistent with the tightening direction of the traction belt.

[0015] In an optional embodiment, the first clamping assembly includes multiple sets of clamping rings, all of which are slidably disposed on the telescopic end; the second clamping assembly includes a clamping plate and three sets of retaining rings, the clamping plate being connected to the telescopic end of the telescopic assembly via a hinge, and the three sets of retaining rings being used to clamp the three branch pipes of the Y-type connector respectively.

[0016] Secondly, a multifunctional anesthesia system includes the aforementioned multifunctional anesthesia machine, and further includes a first force sensor and a controller. The first force sensor is used to detect the tension on the traction belt. The controller is electrically connected to the first force sensor and the servo motor. The first roller has a first damping force when it rotates. When the tension on the traction belt is greater than or less than the upper or lower limit of the first damping force, the controller controls the servo motor to rotate forward or in reverse.

[0017] In an optional embodiment, a second force sensor is further included to detect the tension on the tightening belt; the third roller has a second damping force, which is at least three times the first damping force; when the tension on the tightening belt is greater than the upper limit of the second damping force, the tightening belt tightens under the rotation of the third roller, and at the same time, the servo motor receives a power-off signal.

[0018] The beneficial effects of the embodiments of the present invention are:

[0019] The multifunctional anesthesia machine provided in this embodiment of the invention has an adjustment mechanism configured on the main body of the anesthesia machine. The adjustment mechanism uses a four-bar parallel movement mechanism to enable it to adjust its spatial position, and uses a swing adjustment component and a position adjustment component to enable the third free end to swing and jump. This allows the first clamping component and the second clamping component to adjust the position and orientation when clamping the gas delivery tube and the Y-type connector. After the initial adjustment is completed, fine adjustment and tightening are performed to ensure the connection stability and orientation of the gas delivery tube and the Y-type connector, and reduce the risk of detachment from the gas delivery mask.

[0020] The multifunctional anesthesia system provided in this embodiment of the invention, by configuring a force sensor on the aforementioned multifunctional anesthesia machine, can automatically adapt the posture of the parallel swing arm assembly to the operation of different user operating positions and the magnitude of the applied force, thereby improving the operability of the entire adjustment mechanism while ensuring connection stability.

[0021] In summary, the multifunctional anesthesia machine and system provided in this invention can not only clamp the gas delivery tube but also the Y-shaped connector, making it less likely for the gas delivery tube and the Y-shaped structure to detach. This further reduces the wind direction that could cause the Y-shaped connector to detach from the gas delivery mask. Furthermore, the entire clamping direction is adjustable, allowing the gas delivery tube to be pulled in an adaptive manner according to the specific position and traction direction of the gas delivery mask. This avoids excessive angles between the two directions, which could increase the risk of detachment. Finally, fine-tuning of the pulling and retracting can ensure the straightness of the entire gas delivery tube and the Y-shaped connector, reducing the risk of detachment caused by the shaking of the gas delivery tube.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] Example

[0038] Currently, during preoperative anesthesia, we usually have an assistant who, after adjusting the anesthetic gas parameters, guides the anesthesia into the trachea, connecting the trachea, endotracheal connector, inhalation mask, or nasal / laryngotrachea. After connection, the tube is inserted into the patient's lungs as required. Generally, we wait until after the surgery to disassemble all the tubes one by one. During this process, the assistant will fix and control the anesthesia inhalation tube, especially after it shifts or shakes, and needs to adjust it in time. This method relies on the stability of the controller's grip, which is not only labor-intensive but also prone to human error. To address the aforementioned issues, we previously encountered an anesthesia machine equipped with a mechanical gripping mechanism. This mechanism aimed to clamp and secure the anesthesia tubing. However, while it achieved some tubing clamping functionality, it couldn't effectively adjust the clamping direction. It was more suitable for attaching and clamping the anesthesia tubing during storage than for clamping it during surgery. This is because the anesthesia tubing actively adjusts its clamping direction during the assistant's initial grasp, aligning the main force direction at the connection point with the gas mask as closely as possible, and applying appropriate force to maintain tension, reducing bending and shaking of the tubing and ensuring the stability of the connection between the tubing, connector, and gas mask. Clearly, the existing gripping mechanisms cannot adequately solve these problems. Therefore, this invention provides a multifunctional anesthesia machine and system to overcome the aforementioned problem of insufficient connection stability between the anesthesia tubing, connector, and gas mask during clamping.

[0039] Please see Figure 1 This embodiment provides a multifunctional anesthesia machine including an anesthesia machine body 1, an adjustment mechanism 2, and a clamping mechanism 3. The anesthesia machine body 1 possesses the basic functions of an existing anesthesia machine, which will not be described in detail here. The anesthesia machine body 1 has a circuit system 11, which is used to provide anesthetic mixed gas and recover exhaled waste gas. Specifically, the circuit system 11 includes a first air inlet 12 and a second air inlet 13. Both the first air inlet 12 and the second air inlet 13 are used to connect to anesthesia delivery tubes (not shown), one for supplying gas and the other for recovering gas. The two anesthesia delivery tubes converge through a Y-type connector (not shown) (the converging pipe is generally connected to a gas delivery hood). During surgery, the delivery tubes, connectors, and gas delivery hood are usually assembled as a whole component and then the parameters are adjusted. After passing the test, the anesthesia program begins. In order to reduce the intensity of manual labor and improve the automation of operation during anesthesia, an adjustment mechanism 2 is configured on the anesthesia machine body 1 to adjust the posture of the anesthesia delivery tubes and Y-type connectors, thereby ensuring the connection and stability of the overall component.

[0040] Please refer to the details. Figure 2The adjustment mechanism 2 includes a fixed base 21 and a parallel swing assembly 22. The fixed base 21 is connected to the anesthesia machine body 1. For example, in one embodiment, the fixed base 21 is connected to the top side wall of the anesthesia machine body 1 via a support plate and fasteners. This side can be directly above the circuit system 2 to facilitate subsequent interaction with the anesthesia inlet tube and Y-connector, while also reserving space for the posture change of the parallel swing assembly 22. In some embodiments, the parallel swing assembly 22 adopts a parallel linkage mechanism, such as a four-bar parallel mechanism or a six-bar parallel mechanism, but it needs to have two parallel swing rods that can swing synchronously. The two ends of the parallel swing rods serve as free moving ends, which are used as the basis for connecting with other components and for posture change.

[0041] Specifically, please combine Figure 2 and Figure 3 The fixed base 21 is hinged to the first free end 221 of the parallel swing assembly 22, allowing them to swing relative to each other. A swing adjustment assembly 23 is mounted on the fixed base 21 and drivenly connected to the second free end 222 of the parallel swing assembly 22, enabling the third free end 223 of the parallel swing assembly 22 to swing towards or away from the fixed base 21. It should be noted that the parallel swing assembly 22 has at least three free ends, with the first free end 221 and the second free end 222 located on the same parallel swing rod. The swing adjustment assembly 23 acts on the second free end 222, causing the entire parallel swing rod to swing about the first free end 221 as its center relative to the hinge point with the fixed base 21. This causes the third free end 223 of the other parallel swing rod to swing synchronously (the two parallel swing rods are always relatively parallel), thus achieving the swinging action of moving closer to or away from the fixed base 21.

[0042] The above technical solution provides a basis for the third free end 223 (the parallel swing arm away from the fixed base 21 is intended to reserve space for posture changes) to change position. This connection between the anesthesia infusion tube and the Y-connector reduces motion interference during clamping and makes adjustment more convenient. The clamping mechanism 3 includes a telescopic component 31, a first clamping component 32, and a second clamping component 33. The telescopic component 31 is connected to the third free end, for example, by a fixed connection, providing a structural basis for synchronous posture changes between the telescopic component 31 and the third free end. The first clamping component 32 is slidably connected to the telescopic end of the telescopic component 31, giving it the function of sliding relative to the telescopic component 31. The first clamping component 32 is used to clamp the anesthesia infusion tube, thereby allowing adjustment of the clamping position along the tube's direction. The second clamping component 33 is oscillatingly connected to the telescopic end of the telescopic component 31, so that the second clamping component 33 has the function of swaying relative to the telescopic component 31. The second clamping component 33 is used to clamp the Y-type connector, thereby giving the Y-type connector an adaptive swaying space when clamped, and improving the flexibility of clamping.

[0043] Through the above technical solutions, the initial clamping and initial position adjustment functions of the anesthesia inlet tube and the Y-type connector are realized. However, based on this, the third free end 223 needs to adjust its positioning function and further improve the tightening function of the anesthesia inlet tube and the Y-type connector. Therefore, the fixed base 21 is provided with a position adjustment component 24. The position adjustment component 24 acts on the fourth free end 224 of the parallel swing component 22, so that the third free end 223 can jump away from or towards the fixed base 21, so that the first clamping component 32 and the second clamping component 33 respectively pull and retract the anesthesia inlet tube and the Y-type connector. It should be noted that the third free end 223 and the fourth free end 224 are located on the same parallel swing arm. When the position adjustment component 24 causes the fourth free end 224 to move, the third free end 223 also moves accordingly. In particular, when the fourth free end 224 bounces significantly or slightly towards the fixed base 21, the third free end 223 also bounces significantly or slightly. Here, "bounce" refers to the third free end 223 and the fourth free end 224 simultaneously swaying vertically or moving horizontally towards the fixed base 21. When bouncing significantly, the third free end 223 pulls the anesthesia inlet tube and the Y-connector to retract significantly, which is used to realize the storage of the anesthesia inlet tube and the Y-connector. When bouncing slightly, the third free end 223 pulls the anesthesia inlet tube and the Y-connector to retract slightly, which is used to realize the straightening and pulling back of the anesthesia inlet tube and the Y-connector.

[0044] Through the above technical solution, the movement of the first free end 221 and the second free end 222 drives the orientation adjustment of the third free end 223 and the fourth free end 224, thereby realizing the function of adjusting the clamping direction of the anesthesia infusion tube and the Y-type connector. This avoids the formation of an excessively large angle between the clamping direction of the anesthesia infusion tube and the Y-type connector and the connection direction of the infusion mask, which could cause creases that affect the infusion process or result in excessive normal force at the connection point, leading to instability. Furthermore, the retraction of the fourth free end 224 causes the third free end 223 to retract simultaneously, resulting in a slight straightening and pullback along the clamping direction after initial clamping. This straightens the entire anesthesia infusion tube, the Y-type connector, and the connection with the infusion mask, reducing tubing sway and preventing instability or unreliability in the connection. It ensures that the line connection will not easily detach, replacing manual clamping while retaining the basis for free adjustment of the clamping and tightening direction.

[0045] Please refer to it again. Figure 3In this embodiment, the parallel swing assembly includes a first swing rod 225 and a second swing rod 226, which are two parallel swing rods. Furthermore, two parallel telescopic rods 227 are hinged between the first swing rod 225 and the second swing rod 226, forming a four-bar parallel mechanism. Of course, by increasing the number of telescopic rods 227, a five-bar or six-bar parallel mechanism can be formed. The telescopic rods 227 refer to rods with telescopic functions, such as electric push rods, cylinders, or manual screw rod assemblies. Their purpose is to adjust the distance between the first swing rod 225 and the second swing rod 226, thereby adjusting the distance between the third free end 223 and the fixed seat 21 to accommodate a wide range of adjustments at different clamping positions.

[0046] In addition, in this embodiment, the two ends of the first swing arm 225 are respectively formed as a first free end 221 and a second free end 222, and the two ends of the second swing arm 226 are respectively formed as a third free end 223 and a fourth free end 224. In use, the third free end 223 is located below the fourth free end 224. That is, the third free end 223 is located below, which makes it easier for the first clamping component 32 and the second clamping component 33 at the third free end 223 to directly clamp the anesthesia infusion tube and the Y-type connector downwards.

[0047] To facilitate manual stepless adjustment of the second free end 222, allowing the operator to make adaptive adjustments during clamping, please refer to [link / reference needed]. Figure 4 The swing adjustment assembly 23 includes an adjusting rod 231 and a threaded sleeve 232. The threaded sleeve 232 is rotatably connected to the fixed base 21, particularly in the same direction as the first free end 221, which is rotatably connected to the fixed base 21. One end of the adjusting rod 231 passes through the threaded sleeve 232 and is rotatably connected to the second free end 222. This rotatable connection means that the two can rotate relative to each other but cannot move along the axial direction of the adjusting rod 231 (achieved by adding a limit). The adjusting rod 231 and the threaded sleeve 232 are threadedly engaged. By manually turning the adjusting rod 231, the adjusting rod 231 and the threaded sleeve 232 rotate simultaneously, achieving relative displacement (moving along the axial direction of the adjusting rod 231). As a result, the second free end 222 is pulled back or pushed out, and the entire assembly swings around the first free end 221 as a fulcrum, ultimately achieving the purpose of stepless swing adjustment of the first swing rod 225. At this time, the second swing rod 226 also swings accordingly.

[0048] Since the second pendulum 226 can move relatively parallel to the first pendulum 225, after the second free end 222 (third free end 223) is initially positioned, it needs to maintain its current position and wait for further adjustment. To ensure that the second pendulum 226 remains stationary relative to the first pendulum 225 during this positional change and responds quickly to further adjustments, the position adjustment component 24 needs to possess stable connection and sensitive response. Specifically, please refer to... Figure 5 and Figure 6 The position adjustment component 24 includes a servo motor 241 and a traction belt 242. The servo motor 241 is mounted on a fixed base 21. The first end of the traction belt 242 (a flexible belt) is driven and connected to the servo motor 241, and can be retracted or extended with the forward or reverse rotation of the servo motor 241. The second end of the traction belt 242 is wound around a fourth free end 224 and fixedly connected to a third free end 223. That is, the middle part of the traction belt 242 and the fourth free end 224 are wound around each other and make frictional contact. When the traction belt 242 is retracted or extended, it can drive the fourth free end 224 to move closer to or away from the fixed base 21. At this time, the fixedly connected third free end 223 also moves closer to or away from the fixed base 21. Through the above technical solution, the traction belt 242 can adaptively deform after the position adjustment of the second swing arm 226. While always maintaining relative fixation with the fourth free end 224 and the third free end 223, it can respond quickly and make adaptive adjustments when driven, achieving the purpose of stable connection and sensitive response.

[0049] Based on the above scheme, in order to increase the smoothness of the interaction between the traction belt 242 and each free end and prevent excessive friction from reducing response sensitivity, the position adjustment component 24 further includes a roller group. The roller group includes a first roller 243, a second roller 244, and a third roller 245. The first roller 244 is rotatably mounted on the fixed base 21 via an axle and bearing. The axle of the first roller 244 is driven and connected to the output shaft of the servo motor 241, enabling it to rotate synchronously. The first roller 244 is used to wind around the first end of the traction belt 242. The second roller 244 is rotatably mounted on the fourth free end 224 via an axle and bearing, and is used to wind around the middle part of the traction belt 242 (winding up to one turn through the groove). The third roller 245 is rotatably mounted on the third free end 223 via an axle 246 and bearing, and is used to be fixedly wound around the second end of the traction belt 242. Through the above technical solutions, the traction belt 242 interacts with the roller assembly to achieve the purpose of interacting with the free end. The rolling friction of the roller is relatively small, which can ensure the starting sensitivity. Furthermore, the cooperation between the traction belt 242 and the wheel groove can ensure the stability of the winding motion.

[0050] Considering that using a servo motor 241 and traction belt 242 to actively pull the third free end 223 during the micro-pulling process would result in high control precision and cost, we adopt an alternative fine-tuning method to achieve the micro-pulling and straightening purpose. Specifically, the two ends of the axle 246 of the third roller 245 are rotatably connected to the third free end 223 (through bearings for rotatable connection), and damping pads are provided at the rotatable connection points. The purpose of these damping pads is to prevent the third roller 245 from easily rotating under the pull of the traction belt 242 (the entire parallel swing assembly 22 is made of lightweight plastic, and the driving force can be less than 30N, for example). That is, the fixed connection point between the second end of the traction belt 242 and the third roller 245 will not easily rotate.

[0051] A tightening strap (located in the inner cavity of the third free end 223 end shell) is connected between the axle 246 and the fixed end of the telescopic component 31. The tightening strap (tough strap) is used to adjust the distance between the fixed end of the telescopic component 31 and the third free end 223. Specifically, an inner cavity is provided at the end of the second rocker arm 226 that forms the third free end 223. This inner cavity provides space for the sliding assembly of the fixed end of the telescopic component 31 and also provides space for the tightening strap. One end of the tightening strap is connected to the axle 246, and the other end is connected to the fixed end of the telescopic component 31. When the axle 246 is driven to rotate, the tightening strap can be pulled back or released (this pulling back and releasing is different from the pulling back and releasing of the traction belt 242 in that one is manual fine adjustment and the other is automatic large adjustment), thereby achieving the purpose of adjusting the distance of the fixed end of the telescopic component 31, and thus achieving the purpose of slightly pulling back the first clamping component 32 and the second clamping component 33.

[0052] It should be noted that the tightening direction of the tightening belt is consistent with the tightening direction of the traction belt 242. That is, when the manual external force drives the wheel axle 246 (including the damping pad) to rotate slightly clockwise or counterclockwise, the tightening belt can be synchronously retracted or released. This achieves the effect that while the tightening belt is pulled back along with the first clamping component 32 and the second clamping component 33 (so that the anesthesia infusion tube and the Y-type connector are pulled back and straightened), the traction belt 242 is also retracted and straightened at this time, thereby ensuring the stability of the posture of the entire parallel swing component 22.

[0053] Please refer to it again. Figure 6In some embodiments, the first clamping assembly 32 includes multiple sets of clamping rings 321. Each clamping ring 321 is a semi-ring with an inlay notch, allowing the anesthesia infusion tube to be inserted. All sets of clamping rings 321 are slidably disposed at the telescopic end of the telescopic assembly 31. In particular, the sliding direction of the clamping rings 321 (the purpose of sliding is to support different parts of the anesthesia infusion tube and adjust the overall shape) is consistent with the telescopic direction of the telescopic assembly 31. This allows different parts of the anesthesia infusion tube to maintain a parallel clamping posture with the telescopic assembly 31, achieving controllable clamping direction (this clamping direction can be kept as consistent as possible with the direction of the axial force at the connection of the infusion mask, reducing the risk of bending or detachment).

[0054] The second clamping assembly 33 includes a clamping plate 331 and three sets of retaining rings 332. The clamping plate 331 is connected to the telescopic end of the telescopic assembly 31 via a hinge (e.g., a ball joint, a planar hinge, etc.), allowing the clamping plate 331 to swing freely relative to the telescopic end of the telescopic assembly 31 with the hinge point as the fulcrum. This provides the Y-type connector with adaptive space when clamped, increasing the tolerance for movement after the Y-type connector is connected to the anesthesia infusion tube. The three sets of retaining rings 332 are used to engage the three branches of the Y-type connector. Specifically, the retaining rings 332 are semi-rings, allowing the three branches of the Y-type connector to be easily engaged. Through this technical solution, the Y-type connector has a tendency to twist or rotate relative to the anesthesia infusion tube. When the anesthesia infusion tube twists, the adaptive adjustment of the Y-type connector follows the swing, thus ensuring the stability of the connection.

[0055] This embodiment also provides a multifunctional anesthesia system, which includes the aforementioned multifunctional anesthesia machine. It should be noted that the multifunctional anesthesia machine here refers to a technical solution including a traction belt and a tightening belt, capable of using force detection of the traction belt and tightening belt to determine the current position of the adjusting mechanism 2, so as to respond promptly and adjust the corresponding position. Specifically, the anesthesia system also includes a first force sensor and a controller. The first force sensor is used to detect the tension on the traction belt 242; the controller is electrically connected to the first force sensor and the servo motor 241, thereby forming a control loop capable of force feedback. The first roller 243 has a first damping force when it rotates, which is detected when the first roller 243 is assembled. When the tension on the traction belt 242 is greater than or less than the upper or lower limit of the first damping force (the upper and lower limits are floating upper and lower limits determined based on the first damping force), the controller controls the servo motor 241 to rotate forward or backward. That is, when the force on the traction belt 242 is greater than the upper limit of the first damping force, it indicates that the traction belt 242 is being pulled outward and needs to be released. At this time, the servo motor 241 rotates accordingly to release the traction belt 242. When the force on the traction belt 242 is less than the lower limit of the first damping force, it proves that the traction belt 242 is in a slack state (some external force has replaced the tension converted from the damping force of the traction belt 242 itself) and needs to be retracted. At this time, the servo motor 241 rotates accordingly to retract the traction belt 242.

[0056] Through the above technical solution, when the operator holds the second swing arm 226 and pulls it forward or backward, the servo motor 241 can respond in time and pull out or retract the traction belt 242. When the operator finishes adjusting, the external force disappears when the hand is released, proving that the traction belt 242 is only subjected to the tension of the parallel swing component 22 at this time, and can be maintained at the first damping force of rotation. This makes the whole adjustment process more convenient and faster. The operator only needs to move according to experience to make the adjustment mechanism 2 adaptively change its posture, which greatly improves the convenience and smoothness of operation.

[0057] Based on the above technical solutions, and considering further improvements in ease and smoothness of operation, this multifunctional anesthesia system also includes a second force sensor. This second force sensor detects the tension on the tightening band. The third roller 245 has a second damping force, which is at least three times the first damping force, meaning the third roller 245 will not easily rotate synchronously with the first roller 243. When the tension on the tightening band exceeds the upper limit of the second damping force, the tightening band tightens under the rotation of the third roller 245. This indicates that the operator needs to use a greater force to drive the axle 246 of the third roller 245 to rotate. At this time, the tension on the tightening band increases significantly, maintaining a tightened posture, thereby bringing the telescopic component 31 closer to the third free end 223, achieving a slight tightening of the anesthesia infusion tube and the Y-connector. It should be noted that at this time, the traction belt 242 is subjected to greater tension, but after the controller detects the required value of the second force sensor, it will send a signal to the circuit breaker to instantly cut off the power to the servo motor, preventing the traction belt 242 from being pulled out. This ensures that while the tightening belt is tightening, the traction belt 242 is also slightly pulled and straightened, ensuring high stability of the entire clamping state.
