Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical equipment, and in particular to an electrocardiograph lead wire device with recycling and anti-winding functions. Background Art
[0002] An electrocardiogram (ECG) automatically records the bioelectrical signals generated by myocardial excitation during cardiac activity. As a medical electronic instrument commonly used in clinical diagnosis and scientific research, the myocardium becomes excited before the heart beats, generating a weak current that is conducted through human tissue to various parts of the body. Due to the varying tissue organization and distance from the heart, different areas of the body surface exhibit varying electrical potential variations. This relationship between surface potential and time, generated by electrical activity within the heart, is called an electrocardiogram (ECG). An ECG is the instrument that records these physiological electrical signals.
[0003] Electrocardiographs require a large number of lead wires, with a standard 12-lead system requiring 10 electrode wires. Publication No. CN222323568U proposes an electrocardiograph lead wire storage device comprising an electrocardiograph body, a fixed frame fixedly mounted on the outer wall of the right side of the electrocardiograph body, a lead wire storage compartment located on the right side of the fixed frame, a slide fixedly mounted on the inner wall of the slide, a sealing soft plate slidably connected to the inner wall of the slide, and a clamp fixedly mounted on the inner wall of the lead wire storage compartment. The fixed frame, lead wire storage compartment, and sealing soft plate cooperate to place the lead wires in the lead wire storage compartment, seal the lead wire storage compartment with the sealing soft plate, and then snap the lead wire storage compartment onto the fixed frame, thereby enabling storage of the lead wires after the electrocardiograph is used. By attaching the fixed frame and lead wire storage compartment to the electrocardiograph body, the lead wires are prevented from being lost, allowing them to be easily retrieved and stored when the electrocardiograph body is in use in a ward.
[0004] In the above device, the lead wires are stored in a storage compartment. However, during the storage process, due to the large number of lead wires, generally 5-12, direct storage may cause entanglement and knotting between the lead wires. During use, it is inconvenient to take out multiple lead wires individually, which is inconvenient for specific use.
[0005] Therefore, we propose a storage device that can coil the lead wires separately, so that multiple lead wires can be stored separately to avoid entanglement and overlap between the lead wires and facilitate access. Summary of the Invention
[0006] To achieve the above objectives, the present invention provides an electrocardiograph lead wire device with recycling and anti-entanglement functions, comprising a plurality of wire take-up boxes, which are interconnected by a connecting mechanism. A wire take-up reel is rotatably mounted inside the wire take-up boxes. The wire take-up reel consists of a bottom plate, a top plate, and a connecting column. The bottom plate and the top plate are of the same size, and the connecting column is fixedly mounted at the center of the bottom plate and the top plate. A hollow column that passes through the wire take-up box is fixedly connected to the lower surface of the bottom plate. An L-shaped bending groove is formed on the surface of the connecting column for the lead wire to pass through. A driving motor for driving the hollow column to rotate is mounted on the lower surface of the wire take-up box.
[0007] The front of the wire taking-up box is fixedly connected with a telescopic cylinder, the telescopic end of the telescopic cylinder is fixedly connected with a collar, a wire outlet hole is opened on the front of the wire taking-up box, the collar and the inner wall of the wire outlet hole are fixedly connected with ceramic rings, the telescopic cylinder consists of a sleeve, a telescopic rod and a second spring, the sleeve is fixedly installed on the front of the wire taking-up box, the telescopic rod is slidably installed inside the sleeve, and the second spring is installed between the telescopic rod and the sleeve.
[0008] In one example, the connection mechanism includes a connection box and a connection frame, which are respectively installed on two sides of the wire take-up box, and the position of the connection box corresponds to the position of the connection frame.
[0009] In one example, the front and back sides of the connection box are provided with T-shaped slots, and a T-shaped positioning block is slidably installed inside the T-shaped slot. The T-shaped positioning block and the opposite side of the T-shaped slot are fixedly connected with a connecting spring, and both sides of the T-shaped positioning block are arc-shaped. The front and back sides of the connection frame are provided with positioning openings that are compatible with the T-shaped positioning block.
[0010] In one example, the output end of the driving motor is fixedly connected to a bevel gear, and the surface of the hollow column is fixedly connected to a bevel gear ring that meshes with the surface of the bevel gear.
[0011] In one example, a control box is fixedly connected to the back of the wire taking-up box, a sliding block is slidably installed inside the control box, a first spring is fixedly connected to the opposite surface of the sliding block and the control box, a push block is fixedly connected to the side of the sliding block away from the control box, and the end face of the push block is arc-shaped.
[0012] In one example, a first airbag is installed on the surface of the sliding block opposite to the control box, a second airbag is installed on the surface of the sleeve opposite to the telescopic rod, and the first airbag is connected to the second airbag through a pipe.
[0013] In one example, a pressure valve is installed on the surface of the second airbag, and the pressure valve passes through the sleeve. The air supply diameters of the first airbag and the second airbag are smaller than the exhaust diameter of the pressure valve.
[0014] In one example, two support blocks are fixedly connected to the lower surface of the wire take-up box, and the height of the support blocks is greater than the height of the drive motor.
[0015] In one example, a top column is fixedly connected to the upper surface of the top plate, and the upper surface of the top column is rotatably connected to the inner top wall of the wire take-up box.
[0016] The electrocardiograph lead wire device with recycling and anti-winding functions proposed by the present invention can bring the following beneficial effects:
[0017] 1. The present invention realizes the parallel management of multiple lead wires by arranging a flexible combination of multiple independent wire-receiving boxes, fundamentally avoiding the cross-entanglement of wires. The quick plug-in design of the T-shaped positioning block and the connecting spring supports the free splicing and splitting of the wire-receiving boxes, adapting to the number of lead wires required by different models of electrocardiographs, while ensuring the stability of the connection and avoiding accidental separation during use. The width design of the wire-receiving box significantly increases the distance between the lead wires, further reducing the possibility of contact and entanglement of adjacent wires.
[0018] 2. The present invention sets a driving motor to drive the hollow column to drive the take-up reel to rotate, thereby realizing one-button automatic storage of the lead wire, significantly reducing manual operation time, and is particularly suitable for emergency scenarios. During the take-up process, the arc-shaped end face of the push block is compressed as the radius of the lead coil increases, and the first spring applies tension in the reverse direction to ensure that the lead wire is tightly coiled and the tension is uniform, which not only avoids loosening and falling off, but also prevents deformation of the wire due to excessive extrusion.
[0019] 3. The present invention sets up a first airbag and a second airbag pressure feedback system. When the lead coil squeezes the push block, the first airbag is pressurized to transport gas to the second airbag, triggering the collar to actively push the lead line forward. The pressure valve controls the rhythm of gas release to achieve reciprocating motion of the collar, greatly improving the straightening efficiency. This mechanism relies entirely on the mechanical structure to operate autonomously, without the need for additional electricity or human intervention, which not only reduces energy consumption but also improves the reliability of the device.

In this specification, the schematic expressions of the above terms do not necessarily refer to the same scheme or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more schemes or examples.
[0035] like Figures 1 to 5 As shown, the present invention proposes an electrocardiograph lead wire device with recycling and anti-winding functions, including a wire take-up box 1. The number of wire take-up boxes 1 is determined according to the number of lead wires on the electrocardiograph. The wire take-up boxes 1 are connected end to end. A connection box 2 and a connection frame 3 are installed on both sides of the wire take-up box 1. The connection box 2 is inserted into the connection frame 3, and a T-shaped slot is provided on the front and back of the connection box 2. A T-shaped positioning block 5 is slidably installed inside the T-shaped slot. The T-shaped positioning block 5 is fixedly connected to the opposite surface of the T-shaped slot with a connecting spring 4. Both sides of the T-shaped positioning block 5 are arc-shaped. The front and back of the connection frame 3 are provided with a There is a positioning port, and a T-shaped positioning block 5 is inserted in the positioning port. When the connection box 2 is inserted into the connection frame 3, the arc surface of the T-shaped positioning block 5 is subjected to force, and the T-shaped positioning block 5 is received in the T-shaped groove, and the connecting spring 4 is squeezed. When the T-shaped positioning block 5 moves to the positioning port, the elastic force of the connecting spring 4 pushes the T-shaped positioning block 5 to be inserted into the positioning port, and the connection between the adjacent wire-taking boxes 1 can be completed. When the wire-taking box 1 is pulled, the arc surface of the T-shaped positioning block 5 will be received again under force, and the splitting between the wire-taking boxes 1 can be completed. The wire-taking box 1 has a certain width, which can open the spacing between the lead wires to a large extent and the winding between the lead wires.
[0036] In order to facilitate the storage of the lead wire in the wire take-up box 1, a wire take-up reel 6 is rotatably installed inside the wire take-up box 1. The wire take-up reel 6 consists of a bottom plate 601, a top plate 602 and a connecting column 603. The upper surface of the top plate 602 is fixedly connected to the top column. The upper surface of the top column is rotatably connected to the inner top wall of the wire take-up box 1. The bottom plate 601 and the top plate 602 are the same size, and the connecting column 603 is fixedly installed at the center of the bottom plate 601 and the top plate 602. The bottom of the wire take-up box 1 is provided with a The rotating hole, the inner wall of the rotating hole is connected to the hollow column 7 through a bearing, and an L-shaped bending groove for the lead wire to pass through is opened inside the connecting column 603, and the wire inlet of the L-shaped bending groove is connected to the inside of the hollow column 7, and the wire outlet of the L-shaped bending groove is located in the middle of the connecting column 603. The lead wire passes through the hollow column 7 and through the L-shaped bending groove. When the take-up reel 6 rotates, the lead wire will be driven to be wound on the take-up reel 6, thereby completing the storage of the lead wire.
[0037] A driving motor 8 is fixedly connected to the bottom of the wire take-up box 1, and the driving motor 8 drives the hollow column 7 to rotate through a bevel gear set. The output end of the driving motor 8 is fixedly connected to a bevel gear, and the surface of the hollow column 7 is fixedly connected to a bevel gear ring that meshes with the surface of the bevel gear. The driving motor 8 drives the bevel gear to rotate, which can drive the bevel gear ring to rotate, thereby driving the hollow column 7 to rotate.
[0038] The first spring 12 is pushed and squeezed by the push block 11, and the reverse elastic force of the first spring 12 pushes the push block 11 to give the lead coil a reverse force, which will make the lead wires stick to each other, ensuring that the lead wires are tight after being stored.
[0039] In the process of winding the wire, in order to avoid the bending of the lead wire, it is necessary to straighten the lead wire in advance. A telescopic cylinder 13 is fixedly connected to the front of the wire-winding box 1, and a ring 14 is fixedly connected to the telescopic end of the telescopic cylinder 13. A wire outlet hole is opened at the position of the wire-winding box 1 facing the ring 14. A ceramic ring 15 is fixedly installed on the inner wall of the wire outlet hole and the ring 14. The telescopic cylinder 13 consists of a sleeve 1301, a telescopic rod 1302 and a second spring 1303. The sleeve 1301 is fixedly installed on the front of the wire-winding box 1, the telescopic rod 1302 is fixedly connected to the ring 14, and the telescopic rod 130 2 is slidably mounted inside the sleeve 1301, and the two ends of the second spring 1303 are connected to the sleeve 1301 and the telescopic rod 1302 respectively. During the process of winding the lead wire, when the bent state of the lead wire is stored, the lead wire gives the ring 14 a lateral thrust. At this time, the ring 14 will move toward the wire-receiving box 1, and the second spring 1303 will be squeezed. When the elastic force of the squeezed second spring 1303 can overcome the lateral thrust, the second spring 1303 will push the ring 14 forward. In this way, the ring 14 can be moved back and forth during the storage process to straighten the lead wire.
[0040] A first airbag 16 is installed in the control box 9. The two ends of the first airbag 16 are fixedly connected to the inner wall of the control box 9 and the surface of the sliding block 10 respectively. When the sliding block 10 squeezes the first spring 12, the first airbag 16 is squeezed. A second airbag 17 is installed in the sleeve 1301 and is connected to the first airbag 16. When the first airbag 16 is squeezed, the gas in the first airbag 16 is transported to the second airbag 17, which will expand the second airbag 17 and actively push the telescopic rod 1302 to move, so that the ring 14 can straighten the lead wire. A pressure valve 18 is installed on the surface of the second airbag 17. The exhaust port of the pressure valve 18 is large. Regarding the air supply port connecting the first airbag 16 and the second airbag 17, as the second airbag 17 expands, the second spring 1303 is stretched, and the pressure inside the second airbag 17 increases. When the exhaust pressure of the pressure valve 18 is reached, the pressure valve 18 opens to deflate, and the deflation speed is greater than the intake speed. Under the pulling force of the second spring 1303, the second airbag 17 will be quickly retracted, and the pressure valve 18 will be closed after the pressure becomes smaller, and the second airbag 17 will be inflated again. In this way, the ring 14 can be moved back and forth significantly to straighten the lead wire, and the whole process is carried out autonomously when it is retracted, which is convenient to use.
[0041] Two support blocks are installed at the bottom of the wire take-up box 1. The two support blocks lift the drive motor 8 to prevent the drive motor 8 from directly contacting the placement surface. At the same time, counterweights can be placed on the support blocks to ensure that the device is stably placed on the placement surface. Mounting parts can also be connected to the support blocks so that the device can be fixedly installed on the electrocardiograph for easy transportation.
[0042] Working principle: When using the device, multiple wire-taking boxes 1 are connected. When the connecting box 2 is inserted into the connecting frame 3, the arc surface of the T-shaped positioning block 5 is subjected to force, and the T-shaped positioning block 5 is accommodated in the T-shaped groove. The connecting spring 4 is squeezed. When the T-shaped positioning block 5 moves to the positioning port, the elastic force of the connecting spring 4 pushes the T-shaped positioning block 5 to be inserted into the positioning port, and the connection between the adjacent wire-taking boxes 1 is completed. The lead wire is pulled, and the wire-taking reel 6 releases the lead wire. After use is completed, the drive motor 8 is started, and the drive motor 8 drives the bevel gear to rotate, and the hollow column 7 is driven to rotate through the bevel gear ring. The wire-taking reel 6 rotates, and the wire-taking reel 6 winds the lead wire. The lead wire overlaps with the push block 11. As the lead wire is continuously wound, the push block 11 is pushed, and the push block 11 squeezes the first spring 12 and the first airbag 16. The reaction force of the first spring 12 will make the push block 11 press against the lead wire to ensure the tight coiling between the lead wires, and the first airbag 16 will transport gas to the second airbag 17, which will cause the second airbag 17 to expand and actively push the telescopic rod 1302 to move, so that the ring 14 can straighten the lead wire. As the second airbag 17 expands, the second spring 1303 is stretched, and the pressure inside the second airbag 17 increases. When the exhaust pressure of the pressure valve 18 is reached, the pressure valve 18 opens to deflate. The deflation speed is greater than the intake speed, and under the tension of the second spring 1303, the second airbag 17 will be quickly retracted. The pressure valve 18 will close after the pressure decreases, and the second airbag 17 will be inflated again. In this way, the ring 14 can be moved back and forth significantly to straighten the lead wire.
