Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a lead wire arrangement device for an electrocardiogram device. Background Art

[0002] The lead wire arrangement device for an electrocardiogram device is an auxiliary tool designed specifically for optimizing the cable management of medical devices. It is mainly used to regularize the layout of multiple lead wires during the electrocardiogram detection process, avoiding their disorderly entanglement or accidental detachment. The core of the design of this device lies in solving the problem of low efficiency in manually arranging traditional lead wires.

[0003] In the prior art, a patent document with the Chinese patent publication number CN118845029A discloses a lead wire arrangement device for an electrocardiogram device, including a bed. A support plate is fixedly installed on one side of the bed. A bracket and an electrocardiogram machine support are respectively installed on the side of the support plate facing the bed. A wire groove is provided at the top of the bracket near the edge. A through hole is provided through one side of the electrocardiogram machine support, and an electrocardiogram machine is placed on the electrocardiogram machine support. A lead bus is installed on the electrocardiogram machine. The arrangement device can respectively guide the positions of ten groups of lead wires in the electrocardiogram device according to the specific situation of the patient, and can make the lead wires in the electrocardiogram device automatically retract and reset by pulling down the pull rod after use, so as to avoid the situation of mutual entanglement between multiple groups of lead wires, and can quickly and conveniently complete the arrangement and storage of each lead wire, improving the efficiency of electrocardiogram detection.

[0004] In the actual application process, although the lead wire arrangement device proposed in the above patent document realizes the basic storage function through wire groove guidance and pull rod reset, there are still the following problems: First, the device does not integrate an interference and warning mechanism for the stretched state of the lead wire. When the patient moves violently due to pain, blurred consciousness or sudden convulsions, etc., the lead wire may be mechanically loosened at the connection with the electrode patch or the electrocardiogram machine due to excessive stretching, interfering with the accurate diagnosis of critical diseases (such as ventricular fibrillation). Second, the device relies on fixed wire grooves and unified retraction and release strokes to rigidly restrict the movement range of the lead wire. However, patients with different body types (such as obese patients with a significantly larger chest circumference than children or emaciated patients) have different requirements for the extension length of the lead wire. In actual applications, the impact of the movement of patients with different body types on the connection stability of the lead wire is different. Therefore, it is necessary to design a lead wire arrangement device for an electrocardiogram device to solve the above technical defects. Summary of the Invention

[0005] To solve the above problems, the present invention provides a lead wire arrangement device for an electrocardiogram device. By dynamically driving the adaptive adjustment of the stretching path when the lead wire is stretched, and combining an elastic energy storage mechanism and an intelligent locking mechanism, a preset hierarchical control of the stretching resistance is achieved. At the same time, the lead wire path constraint is optimized through a deformation linkage feedback mechanism, and an acoustic-optical warning mechanism is integrated to solve the problems of easy entanglement due to rigid constraints and insufficient safety protection of traditional devices.

[0006] To achieve the above object, the technical solution of the present invention is as follows: A lead wire arrangement device for an electrocardiogram device, including a housing. The inner side wall of the housing is fixedly connected with a plurality of partitions, and the plurality of partitions divide the interior of the housing into a plurality of mutually communicating storage cavities. The side wall of the housing is provided with a plurality of electrode plate connection ports respectively corresponding to each storage cavity, and the bottom of the housing is provided with an instrument connection port. Each partition is provided with a fixing cylinder fixedly connected by grooving, and a winding component for winding and storing the lead wire is threadedly connected in each fixing cylinder. An elastic wire retracting component for automatically retracting the lead wire is provided in each winding component. When a patient moves and stretches the lead wire, the mutual friction force generated by the displacement of the lead wire drives the winding component itself to rotate and rise, and at the same time, the retracting force generated by the elastic wire retracting component will affect the smoothness of the stretching of the lead wire as a stretching resistance.

[0007] The surface of each partition is provided with a spiral track, and a wire placement groove is opened in each spiral track. Each spiral track includes a plurality of first arc tracks and second arc tracks that are hinged to form a whole. A deformation transmission component for moving and adjusting the plurality of first arc tracks and second arc tracks is provided on each winding component. When the lead wire is stretched, the deformation transmission component transmits the upward displacement of the winding component into the deformation adjustment of the plurality of first arc tracks and second arc tracks to simultaneously adjust the stretching resistance of the lead wire and the placement path of the lead wire in the wire placement groove.

[0008] A locking component for locking and unlocking the elastic wire retracting function is provided at the bottom end of each fixing cylinder, and a control system is configured in the housing. The plurality of locking components are all in signal connection with the control system.

[0009] The technical principle of the above solution is as follows: The partition installed inside the device divides the outer shell into multiple storage cavities, and each storage cavity corresponds to a set of lead wires. When the patient moves and stretches the lead wires, the wire winding component designed in the fixed cylinder can wind and store the lead wires, and can also drive the rotation and rise through the friction force generated by the displacement of the lead wires. At the same time, the recovery force provided by the elastic return wire component in the wire winding component serves as the stretching resistance to limit the excessive stretching of the lead wires; in addition, due to the design of the spiral track, the wire placement groove in the spiral track provides a fixed path for the lead wires, and the spiral track is composed of a first arc track and a second arc track that are hinged to each other. When the lead wires are stretched, the deformation transmission component converts the displacement of the wire winding component into the deformation driving force of the spiral track, thereby dynamically adjusting the stretching resistance and path of the lead wires, so that the path of the lead wires can be dynamically adjusted according to the activities of the patient; finally, the design of the locking component can lock or unlock the elastic return wire function, allowing medical staff to adjust the stretching resistance mode of the lead wires according to the specific situation of the patient. The control system can receive the locking instructions from the medical staff and can also monitor the stretching state of the lead wires in real time. Once the stretching of the lead wires is restricted, the infrared sensor transmits the signal to the analysis and control unit, triggering the corresponding buzzer alarm and indicator light to achieve audible and visual alarms.

[0010] The following are the beneficial effects of adopting the above solution:

[0011] 1. In this solution, a mechanical friction drive is designed to displace the wire winding component, and the elastic return wire component stores energy and applies force in the reverse direction to dynamically balance the stretching and recovery of the lead wires. Through the combined action of the friction force generated by the stretching of the lead wires and the elastic return wire component, a dynamic resistance is formed to prevent the lead wires from being overstretched or loosened due to sudden movements of the patient, ensuring the stability of the connection of the electrocardiogram device.

[0012] 2. In this solution, during the stretching process of the lead wires, the displacement of the wire winding component can trigger the geometric deformation of the spiral track through the deformation transmission component, thereby changing the path curvature and resistance distribution, realizing dynamic adjustment according to the change of the stretching length, adaptively adjusting the lead wire direction and contact pressure, reducing the risk of self-winding, and meeting the activity needs of patients with different body types. In addition, the existence of the resistance can be felt by the patient during the activity through the pulling of the electrode patches, enabling the patient to be aware of the problem of excessive activity.

[0013] 3. In this solution, through the combination of the locking component and the control system, the length of the lead wires where the movement is blocked can be adjusted. After the medical staff install the electrode patches according to the body type of the patient, since the length of the lead wires is fixed and the length that can support the patient's activities is limited and fixed, adjusting the length of the elastic return wire can realize the personalized setting of the lead wire length for patients with different body types.

[0014] Furthermore, the winding components all include hollow displacement winding cylinders. Spiral grooves are provided on the side walls of the displacement winding cylinders, and elastic layers are fixedly connected to the inner walls of the spiral grooves. When the lead wire is stretched and displaced, the friction between the lead wire and the corresponding elastic layer replaces the friction between the lead wire and the spiral groove to drive the displacement of the displacement winding cylinder.

[0015] Beneficial effects: The design of the elastic layer in the spiral groove can enhance the friction between the lead wire and the groove wall, ensure the stable driving of the displacement winding cylinder to rotate and rise when the lead wire is stretched, avoid slipping or accidental loosening, and at the same time reduce the surface wear of the lead wire caused by friction.

[0016] Furthermore, the elastic return wire components all include coiling telescopic cylinders. Torsion springs are provided between the coiling telescopic cylinders and the displacement winding cylinders. Both ends of the torsion springs are fixedly connected to the outer side wall of the coiling telescopic cylinder and the inner side wall of the displacement winding cylinder respectively. The bottom end of the coiling telescopic cylinder extends below the displacement winding cylinder and extends below the fixed cylinder body.

[0017] Beneficial effects: The torsion springs connect the coiling telescopic cylinders and the displacement winding cylinders, accumulate elastic potential energy when the lead wire is stretched, and drive the displacement winding cylinder to reset when released, realizing the adaptive recovery of the lead wire, maintaining the tension of the wire body, and preventing the accumulation of redundant cables.

[0018] Furthermore, the coiling telescopic cylinders are all made of magnetic material.

[0019] Beneficial effects: The coiling telescopic cylinders made of magnetic material cooperate with the locking components, and are quickly fixed or released through magnetic attraction, improving the response speed and reliability of the locking components, and ensuring the precise control of the elastic return wire function.

[0020] Furthermore, the locking components all include electromagnets fixedly connected to the bottom end of the fixed cylinder. Sliding openings are provided in the central parts of the electromagnets. The outer side walls of the coiling telescopic cylinders are slidably matched with the inner side walls of the corresponding sliding openings. A control system is configured in the housing, and several electromagnets are all signal-connected to the control system.

[0021] Beneficial effects: The electromagnets are magnetically attracted and matched with the coiling telescopic cylinders through the sliding openings, and are controlled to open and close by the instructions of the control system, dynamically switching between the free stretching and resistance locking modes of the lead wire to adapt to the requirements of different clinical scenarios (such as electrode patch installation or patient activity monitoring).

[0022] Furthermore, the deformation transmission components all include push rods hinged to the top ends of the coiling telescopic cylinders. The push rods all include hinge rods and several push blocks. One end of each push block is welded to the hinge rod, and the other end of each push block away from the hinge rod is hinged with a hoop block. The bottoms of the hoop blocks are all attached to the hinge points of the adjacent second arc-shaped rails. Support cylinders are rotatably connected to the top ends of the displacement winding cylinders. Connecting rods are hinged to the sides of the support cylinders away from the displacement winding cylinders. One end of the connecting rod away from the displacement winding cylinder is hinged to the hinge rod.

[0023] Beneficial effects: The linkage design of the push rod and the hoop block converts the displacement of the wire winding component into the deformation driving force of the spiral track, dynamically adjusts the curvature and contact pressure of the lead wire path, and avoids winding or kinking caused by disorderly stretching of the cable.

[0024] Furthermore, one end of adjacent first arc tracks close to each other is hinged to each other and is connected to the partition through a fixed hinge. One end of adjacent first arc tracks and second arc tracks close to each other and one end of adjacent second arc tracks close to each other are hinged to each other and are connected to the partition through a sliding hinge.

[0025] Beneficial effects: The combination of the fixed hinge and the sliding hinge enables controllable deformation of the spiral track. When stretching, the hinge points of the second arc track slide radially, adjusting the geometric constraints of the lead wire path and balancing the patient's freedom of movement and the cable stability.

[0026] Furthermore, the cross-sectional area of the wire placement groove is larger than the diameter of the lead wire.

[0027] Beneficial effects: The cross-sectional area of the wire placement groove is slightly larger than the diameter of the lead wire, ensuring that the cable can slide freely in the groove while preventing it from deviating from the preset path through geometric limitation, reducing the operation complexity.

[0028] Furthermore, a plurality of buzzer alarms corresponding to each storage cavity are fixedly connected to the outer side wall of the housing. An indicator light fixedly connected to the outer side wall of the housing is provided on one side of each buzzer alarm. A plurality of buzzer alarms and indicator lights are all connected to the control system in a signal connection manner.

[0029] Beneficial effects: The sound and light alarm module is linked with the control system, triggers a warning when the stretching of the lead wire exceeds the limit, timely reminds medical staff to intervene, avoids connection loosening or equipment damage, and improves the monitoring safety.

[0030] Furthermore, the control system includes a locking control module and an alarm trigger module;

[0031] The locking control module is used to receive the locking instruction input by medical staff, control the opening and closing of the electromagnet according to the instruction, drive the electromagnet to lock or unlock the elastic return wire function, and control the stretching resistance mode of the lead wire.

[0032] The alarm trigger module includes an infrared sensor and an analysis and control unit. The infrared sensor is installed at the hinge point of one end of adjacent second arc tracks close to each other, and is used to collect and detect whether the displacement of the second arc track reaches the alarm threshold.

[0033] The analysis and control unit is used to receive the signal transmitted by the infrared sensor. When receiving the signal indicating limited stretching transmitted by the infrared sensor, it transmits the signal to the corresponding buzzer alarm and indicator light to activate the sound and light alarm.

[0034] Beneficial effects: The locking control module adjusts the resistance mode of the lead wire through an electromagnet to meet personalized needs; the alarm trigger module uses an infrared sensor to monitor the variable of the spiral track, accurately judges the stretching threshold and activates the sound and light alarm to achieve hierarchical safety protection.

[0046] The following will be further described in detail through specific embodiments:

[0047] Embodiment 1:

[0048] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 : A lead wire arrangement device for an electrocardiogram device, including a housing 1. A plurality of partitions 2 integrally formed with the housing 1 are provided on the inner side wall of the housing 1. The plurality of partitions 2 divide the interior of the housing 1 into a plurality of coaxial storage chambers 3. An instrument connection port 4 is opened at the bottom of the housing 1. Through holes 5 corresponding to the axis position of the housing 1 are opened on each partition 2. Adjacent storage chambers 3 communicate with each other through the through holes 5 on the corresponding partitions 2. A plurality of electrode patch connection ports 6 corresponding to the plurality of storage chambers 3 are opened on the side wall of the housing 1. This design enables the wire bodies of each lead wire to be mainly stored in the corresponding storage chamber 3. One end of each lead wire connected to the electrode patch passes through the corresponding electrode patch connection port 6. One end of each lead wire connected to the electrocardiogram device converges in the channel formed by the communication of a plurality of through holes 5 and finally passes through the instrument connection port 4 to be connected to the electrocardiogram device.

[0049] During the electrocardiogram monitoring process, the patient's daily activities may stretch the lead wires. To retract the stretched lead wires in this part, fixing cylinders 7 with openings at both ends are welded to the partition plates 2 with slots. Through holes 8 are provided on the side walls of the fixing cylinders 7 above the corresponding partition plates 2. A wire winding assembly 9 for winding and storing the lead wires is provided in each fixing cylinder 7. Specifically, as Figure 5 shown, each wire winding assembly 9 includes a hollow displacement wire winding cylinder 901. Spiral grooves 902 are provided on the side walls of the displacement wire winding cylinders 901 for clamping the lead wires. Elastic layers 903 are adhered to the inner walls of the spiral grooves 902 to increase the friction between the lead wires and the side walls of the spiral grooves 902. When the lead wires are subjected to a traction force, due to the friction between the lead wires and the side walls of the spiral grooves 902, the displacement wire winding cylinders 901 will tend to rotate and rise along the extension direction of the spiral grooves 902. Threaded protrusions integrally formed with the displacement wire winding cylinders 901 are further provided on the side walls of the displacement wire winding cylinders 901. The threaded protrusions have the same pitch as the corresponding spiral grooves 902 and are arranged in an interlaced manner. Threaded grooves corresponding to the threaded protrusions are provided on the inner side walls of the fixing cylinders 7. The displacement wire winding cylinders 901 are in spiral sliding fit with the corresponding threaded grooves through the threaded protrusions on their surfaces. The design of the threaded grooves and the threaded protrusions improves the stability of the rotation and upward displacement of the displacement wire winding cylinders 901.

[0050] Specifically combined with Figure 2 and Figure 4 shown, an elastic wire retracting assembly 10 for automatically retracting the lead wires is provided below each displacement wire winding cylinder 901. Each elastic wire retracting assembly 10 includes a wire coiling telescopic cylinder 1001. A torsion spring 1002 is provided between the wire coiling telescopic cylinder 1001 and the displacement wire winding cylinder 901. Both ends of each torsion spring 1002 are welded to the outer side wall of the wire coiling telescopic cylinder 1001 and the inner side wall of the displacement wire winding cylinder 901 respectively. The bottom end of the wire coiling telescopic cylinder 1001 extends below the displacement wire winding cylinder 901 and below the fixing cylinder 7. In addition, a locking assembly 11 is provided at the bottom of each fixing cylinder 7. Each locking assembly 11 includes an electromagnet 1101 fixedly connected to the bottom end of the fixing cylinder 7 through a snap structure. A sliding opening 1102 is provided at the center of the electromagnet 1101. The outer side walls of the wire coiling telescopic cylinders 1001 are in sliding fit with the inner side walls of the corresponding sliding openings 1102. The wire coiling telescopic cylinders 1001 are made of magnetic materials. A control system is configured in the housing 1. A plurality of electromagnets 1101 are in signal connection with the control system. The wire body of the lead wire in the storage cavity 3 extends through the spiral groove 902 and winds around the surface of the wire coiling telescopic cylinder 1001, and finally passes through the electromagnet 1101 and is in sliding fit with the electromagnet 1101, and extends into the wire coiling telescopic cylinder 1001 in the lower storage cavity 3 until it passes through the instrument connection port 4.

[0051] At the stage of pasting the electrode patch, the electromagnet 1101 is turned off by the control system at this time. At this time, the coiled wire telescopic cylinder 1001 can slide and fit within the sliding port 1102, and medical staff can arbitrarily stretch the length of the lead wire. At this time, the torsion spring 1002 will transfer the displacement of the displacement winding cylinder 901 rotating and rising to the coiled wire telescopic cylinder 1001, causing the coiled wire telescopic cylinder 1001 to follow the displacement winding cylinder 901 to displace synchronously. After the installation and fixation of the electrode patch are completed, the overall length of the lead wire storage is shortened. What is consumed is the sliding distance of the displacement winding cylinder 901 sliding up and down, and the length of the lead wire stuck in the spiral groove 902 on the winding cylinder (i.e., the redundant length used to connect the electrocardiogram device within the coiled wire telescopic cylinder 1001), and the coiled wire telescopic cylinder 1001 rises accordingly.

[0052] During the use of the device, the control system continuously drives the electromagnet 1101 to take effect, making the fixed cylinder 7 and the coiled wire telescopic cylinder 1001 adsorb and fix relatively, restricting the length of the lead wire. When any lead wire is subjected to a pulling force generated by the patient's movement during the process, the overall lead wire shows a tendency to displace outward through the electrode patch connection port 6. Through the design of increasing the friction between the lead wire and the spiral groove 902 by the elastic layer 903, when the overall lead wire displaces, it will also generate an upward traction force along the spiral groove 902 on the displacement winding cylinder 901. Under the action of the traction force, the displacement winding cylinder 901 rotates clockwise and moves upward along the thread groove on the inner side wall of the fixed cylinder 7, and the lead wire wound on the coiled wire telescopic cylinder 1001 extends and unfolds orderly through the wire passing hole 8 during the rotation process. The difference is that at this time, the coiled wire telescopic cylinder 1001 and the electromagnet 1101 are changed from a sliding fit to a fixed connection, and the rotation-limited coiled wire telescopic cylinder 1001 and the rotating displacement winding cylinder 901 cause the torsion spring 1002 to be twisted and accumulate elastic potential energy. When the pulling force is released, the torsion spring 1002 releases the stored elastic potential energy, driving the displacement winding cylinder 901 to rotate counterclockwise and move downward to reset, and the spiral groove 902 winds and retracts the pulled-out lead wire through the rotational movement, realizing the adaptive retraction of the lead wire.

[0053] Due to the limited length of the lead wire, if the lead wire is continuously pulled out, it may cause the mechanical disconnection of the connection between the lead wire and the electrocardiogram instrument, and even pull the electrocardiogram instrument, resulting in the instrument falling and being damaged. For this reason, spiral tracks 12 are provided on the partition plate 2, and wire placement grooves 13 are opened in the spiral tracks 12. The outer end of the spiral wire placement groove 13 communicates with the corresponding electrode patch connection port 6, and the inner end of the wire placement groove 13 communicates with the corresponding wire passing hole 8. During the process of the lead wire being subjected to the pulling force and the recovery force of elastic recovery, the design of the spiral track 12 and the wire placement groove 13 geometrically constrains the lead wire, converting the disorderly stretching of the lead wire into a controlled spiral movement, reducing the probability of self-winding of the lead wire storage, and improving the safety and reliability of the electrocardiogram lead wire management.

[0054] The spiral track 12 includes a plurality of first arc tracks 1201 and a plurality of second arc tracks 1202. One end of adjacent first arc tracks 1201 that are close to each other is hinged to each other and is connected to the partition 2 through a fixed hinge (only allowing two first arc tracks 1201 to rotate around the fixed hinge axis). One end of adjacent first arc tracks 1201 and second arc tracks 1202 that are close to each other, and one end of adjacent second arc tracks 1202 that are close to each other are hinged to each other and are connected to the partition 2 through a sliding hinge (capable of rotating around the sliding hinge axis and translating radially along the partition 2). It presents a mechanism where the hinge points between adjacent second arc tracks 1202 and between adjacent second arc tracks 1202 and first arc tracks 1201 can move, while the adjacent first arc tracks 1201 are relatively fixed. When this mechanism is stressed, the hinge points between adjacent second arc tracks 1202 slide in a direction away from the spiral center, driving the overall structure formed by a plurality of arc tracks to deform from a logarithmic spiral to an elliptical spiral, changing the curvature of the wire placement path of the lead wire and the contact pressure between the lead wire and each hinge point. The entire deformation process is divided into three stages:

[0055] Initial stage (0 - 50% stretching): The stretching resistance of the lead wire increases linearly, and the patient can perceive mild feedback but the movement is not restricted.

[0056] Warning stage (50 - 80% stretching): The stretching resistance of the lead wire increases exponentially, and the tactile prompt is significant.

[0057] Locking stage (>80% stretching): The stretching resistance of the lead wire jumps, forcibly restricting further stretching of the lead wire.

[0058] Particularly, the top ends of the coiling telescopic cylinders 1001 all extend above the displacement winding cylinder 901. A deformation transmission component 14 for moving and adjusting a plurality of first arc tracks 1201 and second arc tracks 1202 is provided at the top ends of the coiling telescopic cylinders 1001. Specifically, as Figure 6As shown in the figure, the deformation transmission assembly 14 includes push rods hinged to the top end of the coiled wire telescopic cylinder 1001. The push rods include hinge rods 1401 and a number of push blocks 1402. One end of each push block 1402 is welded to the hinge rod 1401, and a hoop block 1403 is hinged to the end of each push block 1402 away from the hinge rod 1401. The bottom of the hoop block 1403 is in contact with the hinge point of the adjacent second arc track 1202. A support cylinder 1404 is rotatably connected to the top end of the displacement coiling cylinder 901 through a bearing. One side of the support cylinder 1404 away from the displacement coiling cylinder 901 is hinged with a connecting rod 1405, and one end of the connecting rod 1405 away from the displacement coiling cylinder 901 is hinged to the hinge rod 1401. When the displacement coiling cylinder 901 continuously rotates and rises, the connecting rod 1405 rises synchronously with the displacement coiling cylinder 901. Since the coiled wire telescopic cylinder 1001 and the fixed cylinder 7 are restricted in displacement under the action of the electromagnet 1101 at this time, the hinge rod 1401 will lift and swing under the action of the connecting rod 1405 at this time. The structures of the push blocks 1402 on the hinge rod 1401 and the hoop blocks 1403 will apply a thrust away from the spiral center to the hinge point of the adjacent second arc track 1202, prompting the overall structure formed by a number of arc tracks to deform from a logarithmic spiral to an elliptical spiral. This design dynamically links the tensile resistance of the lead wire (the deformation of the spiral track 12) with the pulled-out length of the lead wire (the rotational rise of the displacement coiling cylinder 901), forming a progressive dynamic adjustment of "the longer the stretch, the greater the resistance, and the more significant the deformation".

[0059] In addition, since the displacement coiling cylinder 901 secures the lead wire through the spiral groove 902, the force driving the displacement coiling cylinder 901 to rotate and rise is the frictional force between the lead wire and the side wall of the spiral groove 902 when the lead wire is stretched. When the pulling is slow, the frictional force between the lead wire and the side wall of the spiral groove 902 is relatively small. The deformation conversion of a number of arc tracks will be slow due to the lack of driving force on the displacement coiling cylinder 901, which is beneficial to increasing the threshold of patient movement. When the pulling is too strong (sudden stretching), the frictional force between the lead wire and the side wall of the spiral groove 902 is significantly enhanced due to the speed effect, pushing the displacement coiling cylinder 901 to rotate and rise at a high speed, accelerating the deformation conversion of a number of arc tracks, thereby quickly increasing the tensile resistance of the lead wire and even locking it, achieving the effect of protecting low resistance and ensuring comfort during low-speed stretching, and quickly triggering lock-up to block stretching during high-speed sudden stretching.

[0060] Embodiment 2:

[0061] As shown in the attached Figure 1As shown, the difference from Embodiment 1 is that a number of buzzer alarms 15 corresponding to each storage cavity 3 are also fixedly connected to the outer side wall of the outer shell 1 by screws. An indicator light 16 fixedly connected to the outer side wall of the outer shell 1 by screws is provided on one side of each buzzer alarm 15. A number of buzzer alarms 15 and indicator lights 16 are all connected to the control system in a signal manner. When the lead wire is stretched beyond the safety threshold, the deformation linkage feedback mechanism triggers a hierarchical response signal of the control system by detecting the amount of deformation of the spiral track 12 (such as the displacement amplitude of the hinge point), driving the buzzer alarm 15 to emit a high-frequency warning sound, and synchronously lighting up the indicator light 16 corresponding to the storage cavity 3 to flash, forming a dual acoustic and optical prompt. Through real-time monitoring and an active warning mechanism, intervention is forced before the lead wire is about to reach the limit stretching length, timely reminding medical staff to intervene, avoiding connection loosening or equipment damage caused by excessive stretching of the lead wire. At the same time, the acoustic and optical collaborative alarm improves the warning recognition rate, ensures a quick response in case of emergency, and further guarantees the safety and reliability of the patient monitoring process.

[0062] Embodiment 3:

[0063] The difference from Embodiment 2 is that for a conventional sorting device, the lead wire needs to be kept in a coiled state for a long time for winding and storage. Due to the long-term bending and storage of the electrocardiogram lead wire, the wire material generates a shape memory effect, which in turn causes problems such as difficult storage after re-elongation. The cross-sectional area of the wire placement groove 13 is larger than the diameter of the lead wire. By making the cross-sectional area of the wire placement groove 13 slightly larger than the diameter of the lead wire, redundant space is provided for the lead wire during the dynamic deformation process of the spiral track 12, enabling it to disperse local stress through adaptive fine-tuning of its pose (such as slight offset or torsion) as the path curvature changes, avoiding wire extrusion or bending fatigue caused by overly tight geometric constraints. At the same time, combined with the deformation transmission mechanism of the spiral track 12, the lead wire is always in a low-friction sliding state during the process of hierarchical adjustment of the stretching resistance, reducing the risk of plastic deformation of the material caused by sudden path changes or concentrated contact pressure, thereby extending the service life of the lead wire and maintaining the stability of its electrical performance.

[0064] Embodiment 4:

[0065] As shown in the attached Figure 1 figure, the difference from Embodiment 3 is that the control system includes a locking control module and an alarm trigger module.

[0066] The locking control module receives a locking instruction input by medical staff, controls the opening and closing of the electromagnet 1101 according to the instruction, drives the electromagnet 1101 to lock or unlock the elastic return wire function, and controls the stretching resistance mode of the lead wire.

[0067] The alarm trigger module includes an infrared sensor and an analysis and control unit. The infrared sensor is installed at the hinge point of the adjacent second arc track 1202 near the mutually close end, and is used to collect and detect whether the displacement of the second arc track 1202 reaches the alarm threshold.

[0068] The analysis and control unit receives the signal transmitted by the infrared sensor. When receiving the signal representing limited stretching transmitted by the infrared sensor, it transmits the signal to the corresponding buzzer alarm 15 and indicator light 16 to activate the sound and light alarm.

[0069] Obviously, the above embodiments are only examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
