Description

Technical Field

[0001] This utility model relates to the field of electrocardiogram electrode management technology, specifically an electrocardiogram electrode constrictor. Background Technology

[0002] As a key medium connecting patients and electrocardiogram (ECG) machines, the management and maintenance of ECG electrode wires are crucial for ensuring data accuracy and ease of operation. ECG electrode wire management often faces problems such as wire tangling, damage, and inconvenience. To solve this problem, an ECG electrode wire retractor has been developed.

[0003] However, existing ECG electrode wire retractors have certain drawbacks in use. Some retractors retract from both ends simultaneously, while others retract from only one end. The two-end retractor requires the operator to use both hands simultaneously, making it inconvenient. The one-end retractor requires one end of the electrode wire to be fixed to a roller inside the retractor. This necessitates the use of a rotatable connector to connect the wire end to the ECG device, which is prone to damage and may lead to poor contact. Existing ECG electrode wire retractors lack effective wire management mechanisms, such as wire clips or wire slots, to secure and store the wires, resulting in loosening, tangling, and damage during use and storage. Furthermore, existing ECG electrode wire retractors use springs instead of motors for winding, which may prevent precise control of the winding process, leading to uneven winding, low efficiency, and ultimately, damage to the electrode wires during winding, affecting their lifespan and reliability. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides an electrocardiogram electrode wire constrictor.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an electrocardiogram electrode wire retractor, including a housing, a wire coiling plate, a wire coiling assembly, and a wire take-up plate. The housing has a circular cross-section. The wire take-up plate is horizontally fixed in the middle of the housing. A spiral take-up groove plate is fixed on the top of the take-up plate. A wire-passing hole is opened on the top of the take-up plate and inside the spiral take-up groove plate. The wire-passing hole allows the electrode wire to pass through the take-up plate. This design simplifies the wire path, allowing the wire to move smoothly from the inside of the housing to the outside, reducing wire friction and damage. The wire coiling plate is rotatably fitted above the take-up plate. A reserved groove is opened on the top of the wire coiling plate. The wire coiling assembly includes a wire channel positioning block and a wiring plate. The design of the wire coiling assembly allows the wire channel positioning block and the wiring plate to... Working in tandem, this design ensures precise positioning and movement of the wire during the winding process. The movement of the guide positioning block and the rotation of the wiring board allow the wire to be effectively wound along a predetermined path, reducing wire tangling and damage. The guide positioning block moves within a pre-reserved slot, while the wiring board rotates around the bottom of the guide positioning block and slides within the spiral take-up groove. The guide positioning block and the wiring board each have a wire-passing hole and a wire-passing hole, respectively. The design and position of the coiling plate allow it to work collaboratively with the take-up plate. This layout allows the coiling plate to interact directly with the wiring board, effectively pressing the electrode wire into the spiral take-up groove. This design improves the efficiency of the retractor and makes the wire winding more uniform and compact.

[0006] The spiral take-up groove plate has a partial cross-section with a "U" shape. The two ends of the reserved groove are aligned vertically with the two ends of the spiral take-up groove plate. A motor that drives the coil plate to rotate is vertically installed at the bottom center of the take-up plate. The "U" shape design of the spiral take-up groove plate allows the electrode wire to be neatly wound along the spiral path of the groove plate. This structure helps to reduce wire twisting and damage, while providing a clear path, making wire winding more orderly and efficient. In addition, this structure also helps to keep the wire clean and facilitates management and use.

[0007] Preferably, a wire clip is fixed to the top of the take-up plate near the wire hole by bolts, and a wire receiving groove is opened at the bottom of the take-up plate, with one end of the wire receiving groove communicating with the wire hole. The wire clip is designed to fix the wire and prevent the wire from sliding and loosening during use, so that the electrode wire in the constrictor can maintain a stable and good connection with the electrocardiogram equipment.

[0008] Preferably, the side of the box body has an inlet hole that is aligned with and passes through the cable tray, and the top of the box body is covered with a cover, with an outlet hole at the center of the top of the cover.

[0009] Preferably, the reserved groove has rail grooves on both sides of the reserved groove, and rollers are installed on both sides of the track positioning block. The two rollers roll and cooperate in the two rail grooves respectively. The design of the rail grooves and rollers allows the track positioning block to move smoothly in the reserved groove. This design reduces the friction and damage of the track positioning block during the movement process and improves the movement efficiency and accuracy of the track positioning block.

[0010] Preferably, the inner walls on both sides of the spiral take-up groove are provided with grooves, and the wiring board is fixed with sliders on both sides. The two sliders slide and engage in the two grooves respectively. The design of the grooves and sliders allows the wiring board to slide smoothly in the spiral take-up groove. This design reduces the friction and damage of the wiring board during the sliding process and improves the sliding efficiency and accuracy of the wiring board.

[0011] Preferably, two support plates are vertically fixed at the top of the line positioning block, and two wire-passing pressure rollers are rotatably engaged between the two support plates. The wire-passing pressure rollers are designed to fix and squeeze the electrode ends of the electrode wire. This design ensures the stability of the electrode wire during use and prevents the wire from springing back and loosening.

[0012] The beneficial effects of this utility model are:

[0013] (1) The electrocardiogram electrode wire retractor of this utility model has a coil plate rotatably fitted above the take-up plate and a wire board slidably fitted inside the spiral take-up groove plate. When the coil plate rotates, the wire board will move along the spiral of the spiral take-up groove plate. Since the electrode wire runs through the wire board, the wire board can press the electrode wire into the spiral take-up groove plate to realize the retraction function. This retraction method uses the wire board to wind the electrode wire into the spiral take-up groove plate and retracts from one end of the electrode wire without affecting the other end, so that the other end can be directly connected to the electrocardiogram equipment without the need for a rotatable connector. This avoids the problem of poor contact of the rotary connector affecting the use. Since it can realize the retraction function at one end, the operator only needs to fix the retractor and can operate it with one hand to directly pull out the electrode wire, which greatly improves the convenience of use.

[0014] (2) The electrocardiogram electrode wire retractor described in this utility model, through the design of wire clips, wire storage grooves, wiring boards and coiling boards, ensures that the electrode wires will not loosen during use and storage. The wire clips fix the wires, the wire storage grooves store the wires, the wiring board presses the wires into the grooves when it moves in the spiral wire storage groove, and the coiling board restricts the wires in the spiral wire storage groove to prevent the wires from coming out. These structures work together to effectively prevent the wires from loosening. This design not only keeps the wires neat and orderly, but also avoids the wires from getting tangled and damaged, thus improving the efficiency and safety of use.

[0015] (3) The electrocardiogram electrode wire retractor described in this utility model uses a motor to drive the winding. Compared with traditional springs, the motor can precisely control the winding process, making the winding more uniform and efficient. This avoids the problem of electrode wire damage caused by excessive speed during the winding process. In addition, since the wire positioning block of the coiling assembly is located in the reserved groove, the wire positioning block will be subjected to the force in the direction of rotation of the coiling plate. The transmission of this force ensures the synchronous movement of the wire positioning block and the wiring plate, improving the accuracy and consistency of the coiling process. The wiring plate moves along the spiral winding groove plate. This spiral movement design allows the wire to be wound evenly, reducing wire twisting and damage, and extending the service life of the wire. Attached Figure Description

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figures 1-8 As shown, the electrocardiogram electrode wire retractor of this utility model includes a housing 1, a coiling plate 3, a coiling assembly 4, and a take-up plate 5. The housing 1 has a circular cross-section. The take-up plate 5 is horizontally fixed in the middle of the housing 1. A spiral take-up groove plate 501 is fixed on the top of the take-up plate 5. A wire-passing hole 505 is opened on the top of the take-up plate 5 and inside the spiral take-up groove plate 501. The wire-passing hole 505 allows the electrode wire to pass through the take-up plate 5. This design simplifies the wire path, allowing the wire to move smoothly from the inside of the housing 1 to the outside, reducing wire friction and damage. The coiling plate 3 is rotatably fitted above the take-up plate 5. The cable winding assembly 4 includes a pre-reserved slot 301 and a cable guide block 401 and a wiring board 404. The design of the cable winding assembly 4 allows the cable guide block 401 and the wiring board 404 to work together. This design ensures precise positioning and movement of the cable during the winding process. The movable engagement of the cable guide block 401 and the rotational engagement of the wiring board 404 allow the cable to be effectively wound along a predetermined path, reducing cable tangling and damage. The cable guide block 401 is movably engaged within the pre-reserved slot 301, and the wiring board 404 is rotatably engaged at the bottom of the cable guide block 401. The wiring board 404 also slides within the spiral take-up groove plate 501. The position block 401 and the wiring board 404 are respectively provided with a wire-passing hole 402 and a wire-passing hole 406. The design and position of the coil plate 3 enable it to work in conjunction with the take-up plate 5. This layout allows the coil plate 3 to interact directly with the wiring board 404, thereby effectively pressing the electrode wire into the spiral take-up groove plate 501. This design improves the working efficiency of the shrinker and makes the wire winding more uniform and tight. In this shrinker, the coil plate 3 is rotatably fitted above the take-up plate 5, and the wiring board 404 is slidably fitted inside the spiral take-up groove plate 501. When the coil plate 3 rotates, the wiring board 404 moves along the spiral of the spiral take-up groove plate 501. Since the electrode wire runs through the wiring board 404, the wiring board 404 can press the electrode wire into the spiral take-up groove plate 501 to achieve the shrinkage function. This shrinkage method uses the wiring board 404 to wind the electrode wire into the spiral take-up groove plate 501, shrinking from one end of the electrode wire without affecting the other end, so that the other end can be directly connected to the electrocardiogram equipment without the need for a rotatable connector. This avoids the problem of poor contact of the rotary connector affecting the use. Since it can achieve the shrinkage function at one end, the operator only needs to fix the shrinker and can operate with one hand to directly pull out the electrode wire, which greatly improves the convenience of use.

[0028] The spiral take-up groove plate 501 has a partial "U"-shaped cross-section. The two ends of the pre-reserved groove 301 are aligned vertically with the two ends of the spiral take-up groove plate 501. A motor 504, which drives the rotating coil plate 3, is vertically mounted at the bottom center of the take-up plate 501. The "U"-shaped design of the spiral take-up groove plate 501 allows the electrode wire to be neatly wound along the spiral path of the groove plate. This structure helps reduce wire twisting and damage, while providing a clear path, making wire winding more orderly and efficient. Furthermore, this structure helps maintain wire cleanliness, facilitating management and use. This retractor uses the motor 504 for winding, which is more efficient than traditional springs. The motor 504 can precisely control the winding process, making the winding more uniform and efficient, and avoiding the problem of damage to the electrode wire caused by excessive speed during the winding process. In addition, since the wire guide positioning block 401 of the coiling assembly 4 is located in the reserved slot 301, the wire guide positioning block 401 will be subjected to the force in the rotation direction of the coiling plate 3. The transmission of this force ensures the synchronous movement of the wire guide positioning block 401 and the wiring plate 404, improving the accuracy and consistency of the coiling process. The wiring plate 404 moves along the spiral of the spiral take-up groove plate 501. This spiral movement design allows the wire to be wound evenly, reducing wire twisting and damage, and extending the service life of the wire.

[0029] In one optional embodiment of this example, a wire clip 503 is fixed to the top of the take-up plate 5 near the wire hole 505 by bolts. A wire receiving groove 506 is provided at the bottom of the take-up plate 5, and one end of the wire receiving groove 506 is connected to the wire hole 505. The wire clip 503 is designed to fix the wire and prevent the wire from sliding and loosening during use, so that the electrode wire in the constrictor can maintain a stable and good connection with the electrocardiogram device.

[0030] In one optional embodiment of this example, the side of the box body 1 has an inlet hole 101 that is aligned with and passes through the wire receiving groove 506. The top of the box body 1 is covered with a box cover 2, and the top center of the box cover 2 has an outlet hole 201. The electrocardiogram electrode wire retractor, through the design of the wire clip 503, the wire receiving groove 506, the wiring plate 404, and the coiling plate 3, ensures that the electrode wires will not loosen during use and storage. The wire clip 503 fixes the wires, the wire receiving groove 506 stores the wires, the wiring plate 404 presses the wires into the groove when it moves in the spiral wire receiving groove plate 501, and the coiling plate 3 restricts the wires in the spiral wire receiving groove plate 501 to prevent the wires from coming out. These structures work together to effectively prevent the wires from loosening. This design not only keeps the wires neat and orderly, but also avoids the wires from tangling and being damaged, improving efficiency and safety.

[0031] In an optional embodiment of this example, rail grooves 302 are provided on both sides of the reserved groove 301, and rollers 403 are installed on both sides of the track positioning block 401. The two rollers 403 roll and cooperate in the two rail grooves 302 respectively. The design of the rail grooves 302 and rollers 403 allows the track positioning block 401 to move smoothly in the reserved groove 301. This design reduces the friction and damage of the track positioning block 401 during the movement process and improves the movement efficiency and accuracy of the track positioning block 401.

[0032] In an optional embodiment of this invention, grooves 502 are provided on both inner walls of the spiral take-up groove plate 501, and sliders 405 are fixed on both sides of the wiring plate 404. The two sliders 405 are slidably engaged in the two grooves 502 respectively. The design of the grooves 502 and the sliders 405 allows the wiring plate 404 to slide smoothly in the spiral take-up groove plate 501. This design reduces the friction and damage of the wiring plate 404 during the sliding process and improves the sliding efficiency and accuracy of the wiring plate 404.

[0033] In one optional embodiment of this example, two support plates 407 are vertically fixed to the top of the line positioning block 401, and two wire-passing pressure rollers 408 are rotatably engaged between the two support plates 407. The wire-passing pressure rollers 408 are designed to fix and squeeze the electrode ends of the electrode wire. This design ensures the stability of the electrode wire during use and prevents the wire from springing back and loosening.

[0034] In use, firstly, pass the electrode ends of the electrocardiogram (ECG) electrode wire sequentially through the inlet hole 101, the threading hole 505, the second thread passage hole 406, the first thread passage hole 402, between the two thread passing pressure rollers 408, and the outlet hole 201, leaving the required winding length outside the outlet hole 201. Use the wire clip 503 to press the wire next to the threading hole 505 tightly, and place the wire at the bottom of the take-up plate 5 into the wire receiving groove 506. Then, drive the coiling plate 3 to rotate via the motor 504, as the wire is coiled... The cable guide positioning block 401 of component 4 is located in the reserved slot 301. The cable guide positioning block 401 is subjected to a force in the rotation direction of the coiling plate 3. Since a wiring plate 404 is provided at the bottom of the cable guide positioning block 401, the wiring plate 404 needs to move along the spiral of the spiral take-up groove plate 501. When the coiling plate 3 rotates, the wiring plate 404 will move along the spiral of the spiral take-up groove plate 501, and the cable guide positioning block 401 will move along the reserved slot 301. The wiring plate 404 of the coiling component 4... 4. Moving the wire within the spiral take-up slot 501 will press the ECG electrode wire into the spiral take-up slot 501. Simultaneously, the end of the ECG electrode wire furthest from the electrode is pressed firmly by the wire clip 503. The wire pressed into the wiring board 404 can only be the electrode end, thus achieving single-end winding of the ECG electrode wire. After winding the ECG electrode wire is complete, the motor 504 can be turned off. The electrode wire wound within the spiral take-up slot 501 is covered by the coil plate 3, preventing it from becoming loose. Finally, it is necessary to... To use the ECG electrode wire, simply pull the electrode tip. As the wire is pulled out, the coil plate 3 rotates in the opposite direction to the wire retraction. Simultaneously, the wiring plate 404 of the coil assembly 4 moves within the spiral take-up groove plate 501 as the electrode wire is pulled out. When the electrode wire is pulled out, the wire pressure roller 408 presses and fixes the electrode tip, preventing the wire from springing back into the retractor and avoiding any loosening issues.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
