Description

Technical Field

[0001] The invention belongs to the field of electrocardiogram acquisition assistance, in particular to an electrocardiogram acquisition electrode fixing device. Background Art

[0002] The ECG acquisition electrode fixture is a key component in the ECG examination process. It is used to ensure stable contact between the electrode and the human skin, thereby accurately collecting the heart's electrical activity signals. In the field of medical diagnosis, ECG examination is an important non-invasive detection method and is widely used in the screening, diagnosis and monitoring of heart disease.

[0003] In actual applications, during the common electrocardiogram (ECG) collection process, medical staff usually use an electrode suction ball to fix the electrode. This traditional limited fixation method relies on the negative pressure adsorption force between the suction ball and the skin. Although it can achieve basic fixation functions in the general population, it has obvious limitations for some patients with thin bodies, loose skin or flat chests.

[0004] Specifically, the existing suction ball type electrode fixing method faces the problems of weak adsorption, easy falling off and poor contact in actual operation. These problems directly lead to frequent interruptions and data fluctuations in the ECG signal acquisition process, which in turn affects the accuracy and repeatability of the test results. Especially for elderly patients, infants and people with low body fat, due to the lack of sufficient adsorption support points on the skin surface, the suction ball is difficult to form an effective sealing environment, and it is very easy to slip or fall off, seriously affecting the detection efficiency and data quality.

[0030] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0031] As attached Figure 1 To the attached Figure 7 As shown:

[0032] Embodiment 1: The present invention provides an electrocardiogram (ECG) acquisition electrode fixing device, comprising a main elastic band 1. A structural groove 2 is defined on one side of the top of the main elastic band 1 and extends through the side wall of the main elastic band 1. The inner cavity of the structural groove 2 is provided with a plurality of limiting mechanisms 5. The limiting mechanisms 5 include a long rod 501. A through groove 1 502 is defined on the top of the inner cavity of the long rod 501. A through groove 3 511 is defined on the inner wall of one side of the long rod 501. The inner cavity of the through groove 3 511 is provided with a plurality of curved plates 2 510. A plurality of latching slots 503 are defined on the inner wall of one side of the through groove 1 502. A fixing block 506 is vertically defined in the inner cavity of one of the latching slots 503. A curved plate 1 509 is provided on one side of the fixing block 506 to match the curved plate 2 510.

[0033] A lead wire 7 is vertically arranged in the inner cavity of the through slot three 511, and one side of the outer circle of the lead wire 7 is in contact with the inner arc surface of the adjacent arc plate two 510, and the other side of the outer circle of the lead wire 7 is in contact with the inner arc surface of the adjacent arc plate one 509. One end of the lead wire 7 passes through the inner cavity of the adjacent through slot three 511 and is fixedly connected to an electrode sheet.

[0034] Both sides of the main elastic band 1 are fixedly connected to the auxiliary elastic band 3, and both sides of the auxiliary elastic band 3 are fixedly connected to the magic tape 4.

[0035] A push plate 505 is vertically arranged in the inner cavity of the long rod 501, and several return springs 504 are fixedly connected to one side of the push plate 505 and along the horizontal direction of the push plate 505. One end of the return spring 504 is fixedly connected to the inner wall of the adjacent long rod 501, and one side of the push plate 505 is against one side of the adjacent fixed block 506.

[0036] As can be seen from the above, when a person uses the electrocardiogram collection electrode fixing device to perform an operation on a patient, the main elastic belt 1 is first fitted to the patient's chest, so that the electrodes preset on the main elastic belt 1 are initially fitted to the patient's chest skin. At this time, the electrodes are roughly in the required position for detection. However, due to individual differences in patients of different body shapes, especially thin people may have flat chests, loose skin, etc., it is difficult to ensure stable contact between the electrodes and the skin by relying solely on the tension of the elastic belt itself. Therefore, it is necessary to further use the adjustment mechanism 6 and the limit mechanism 5 to complete the precise position adjustment of the lead wire 7 and the electrode; specifically, when the doctor When the medical personnel need to adjust the lateral position of the lead wire 7 and the electrode according to the patient's body shape, they can rotate the handle 603 to drive the screw rod 602 to rotate. The rotation of the screw rod 602 causes the screw sleeve 604 to move in its axial direction. Since the screw sleeve 604 is connected to the connecting plate 605, and the connecting plate 605 is fixedly connected to the vertical block 607, the horizontal movement of the screw sleeve 604 drives the vertical block 607 to move smoothly along the slide rail 608 inside the outer box 601, thereby pushing the long rod 501 to move horizontally. The long rod 501 serves as the main supporting structure in the limiting mechanism 5, and its displacement directly drives the short rod connected to it. The position of the lead wire 7 and the bottom electrode thereof is changed by the change of the position of the curved plate 508 and the curved plate 1 509, thereby realizing the lateral fine adjustment of the lead wire 7 and the bottom electrode thereof, ensuring that the electrode can accurately correspond to the skin area of a specific part of the patient; and after completing the lateral adjustment, if the longitudinal position of the electrode needs to be adjusted, the handle 507 can be toggled to disengage the fixing block 506 from the currently engaged slot 503 and slide up and down along the direction of the through slot 1 502. As the fixing block 506 moves, the short rod 508 drives the curved plate 1 509 to move synchronously, releasing the clamping state between it and the adjacent curved plate 2 510. At this time, the lead wire 7 is no longer subject to the limiting effect and can be automatically The ground is adjusted to the required longitudinal height; after the adjustment is completed, the operator slides the fixed block 506 again to re-engage it in the adjacent slot 503. During this process, the push plate 505 compresses the reset spring 504 due to the displacement of the fixed block 506. When the fixed block 506 is completely embedded in the new slot 503, the push plate 505 returns to its original position under the elastic restoring force of the reset spring 504, thereby forming a stable limit support for the fixed block 506. At the same time, the arc plate 1 509 also cooperates with the arc plate 2 510 again with the reset action of the short rod 508 to clamp and fix the lead wire 7, ensuring the stability of the electrode in the longitudinal direction.Finally, the operator wraps the two secondary elastic bands 3 around the patient's body and tightens and fixes them with magic tape 4, so that the entire device fits tightly to the patient's torso, thereby effectively improving the fit and stability between the electrode and the skin, and ensuring the continuity and accuracy of the ECG signal acquisition process. This solution provides an effective solution to the problems of weak adsorption, easy falling off, and poor contact in thin people proposed in the background technology with the traditional suction ball type electrode fixation method. First, through the combined design of the main elastic band 1 and the secondary elastic band 3, combined with the adjustability of the magic tape 4, the device can adapt to patients of different body shapes, especially for thin people with flat chests and loose skin, avoiding the problem of electrode sliding or falling off caused by the lack of sufficient adsorption support points in the traditional suction ball method. Secondly, Adjustment mechanism 6 utilizes a screw rod 602 and a threaded sleeve 604 in conjunction with a connecting plate 605, a vertical block 607, and a slide rail 608, enabling high-precision lateral adjustment of lead wire 7 and electrodes. This ensures that the electrodes accurately correspond to the patient's ECG detection area and improves signal acquisition reliability. Furthermore, components such as the fixing block 506, the latching slot 503, the through slot 1 502, the return spring 504, the push plate 505, the short rod 508, and the curved plates 1 509 and 2 510 in the limiting mechanism 5 work together to support longitudinal position adjustment of lead wire 7. The mechanical snap-fit mechanism allows for rapid positioning and locking, improving operational convenience and enhancing electrode fixation stability. This solves the data fluctuation and acquisition interruption issues associated with poor electrode contact in traditional methods.

[0037] Embodiment 2: This embodiment is basically the same as the previous embodiment, with the difference that one side of the fixed block 506 is in contact with the inner wall of the corresponding slot 503, the top of the fixed block 506 is fixedly connected with a handle 507, two short rods 508 are horizontally arranged between one side of the fixed block 506 and the corresponding arc plate 509, one end of the short rod 508 is fixedly connected to one side of the adjacent fixed block 506, and the other end of the short rod 508 is fixedly connected to the outer arc surface of the adjacent arc plate 509, and the outer ring of the fixed block 506 is adapted to the inner cavity of the through slot 502.

[0038] An adjustment mechanism 6 is provided on one side of the long rod 501, and the adjustment mechanism 6 includes an outer box 601. A screw rod 602 is horizontally provided in the inner cavity of the outer box 601. The outer ring of the screw rod 602 is provided with a screw sleeve 604. Two through grooves 2 606 are provided on the inner wall of one side of the outer box 601. One side of the outer ring of the screw sleeve 604 is fixedly connected to two connecting plates 605. A vertical block 607 is fixedly connected to one side of the top of the long rod 501. One side of the connecting plate 605 passes through the inner cavity of the adjacent through groove 2 606 and is fixedly connected to one side of the vertical block 607.

[0039] A slider 609 is fixedly connected to the other side of the top of the long rod 501 , and a slide rail 608 adapted to the slider 609 is provided at the bottom of the slider 609 , and the bottom of the slide rail 608 is fixedly connected to the top of the main elastic band 1 .

[0040] As can be seen from the above, through the connection setting between the main elastic band 1, the auxiliary elastic band 3 and the magic tape 4, during use, the operator fits the main elastic band 1 to the patient's chest, and then tightens and fixes the auxiliary elastic band 3 around the patient's body through the magic tape 4, so that the entire device can better fit the chest structure of patients with different body shapes, especially for thin or flat-chested people, which can effectively improve the fit between the electrode and the skin. This setting improves the adaptability and wearing stability of the device, and solves the problem of traditional suction ball type electrode fixation method. The sliding and falling problem caused by insufficient adsorption is solved by the coordinated setting between the push plate 505, the return spring 504 and the fixed block 506. When adjusting the position of the lead wire 7 longitudinally, the operator turns the handle 507 to drive the fixed block 506 to move, compressing the return spring 504. After releasing the handle, the return spring 504 pushes the push plate 505 to return to its original position, thereby realizing automatic limiting of the fixed block 506 and ensuring that it is stably connected to the card slot 503. This setting improves the convenience of operation and the self-locking ability of the structure, and enhances the stability of electrode fixation. Through the coordinated arrangement among the fixing block 506, the card slot 503, the handle 507, the short rod 508 and the through slot 1 502, the operator can pull the fixing block 506 to slide along the through slot 1 502 through the handle 507 and switch to the card slot 503 of different heights, thereby adjusting the position of the arc plate 1 509, and then changing the clamping space between it and the arc plate 2 510 to adapt to the height change of the electrode lead wire 7. This arrangement realizes the flexible adjustment of the longitudinal position of the lead wire 7, and improves the applicability and operation of the device. For the convenience of operation, through the coordination between the screw rod 602, the screw sleeve 604, the connecting plate 605, the vertical block 607 and the through slot 606, the operator rotates the handle 603 to drive the screw rod 602 to rotate, so that the screw sleeve 604 moves axially along the screw rod 602, and then drives the connecting plate 605 to push the vertical block 607 to move laterally, thereby realizing the overall lateral movement of the long rod 501 and the limiting component connected thereto. This setting realizes the precise positioning of the electrode and its lead wire 7 in the lateral direction, and improves the accuracy and consistency of signal acquisition.

[0041] Example 3: This example is basically the same as the previous example, except that the bottom of the outer box 601 is fixedly connected to the top of the main elastic band 1, one end of the screw rod 602 is rotatably connected to the adjacent inner wall of the outer box 601 through a rotating shaft, and the other end of the screw rod 602 is fixedly connected to the handle 603 through a shaft sleeve that passes through the adjacent side wall of the outer box 601.

[0042] A plurality of limiting mechanisms 5 are distributed in the inner cavity of the structural groove 2 in a linear array.

[0043] The arc-shaped plate 1 509 and the arc-shaped plate 2 510 have the same size and the same height.

[0044] The inner cavity of the through slot three 511 is connected to the inner cavity of the corresponding long rod 501 , and the inner cavity of the long rod 501 is connected to the inner cavity of the corresponding through slot one 502 , and the plurality of slots 503 are all connected to the inner cavity of the corresponding through slot one 502 .

[0045] As can be seen from the above, through the cooperation between the slider 609 and the slide rail 608, during the lateral adjustment process, the slider 609 slides smoothly along the slide rail 608, providing guide support for the long rod 501 to prevent it from deflecting or shaking during the adjustment process. This setting enhances the stability and accuracy of the adjustment process, ensuring that the electrode is always in the ideal detection position in the lateral direction. Through the fixed connection between the outer box 601 and the main elastic band 1 and the rotating shaft structure between the screw rod 602 and the handle 603, the adjustment mechanism 6 is firmly installed on the main elastic band 1 as a whole. At the same time, the operator can drive the screw rod 602 by rotating the handle 603 to achieve continuous adjustment of the lateral position of the electrode. This setting ensures the stability of the operation of the adjustment mechanism 6 and the convenience of operation. Through the arrangement of multiple limiting mechanisms 5 in the linearly arranged structural groove 2, multiple lead wires 7 can be clamped and fixed by independent limiting components respectively, without interfering with each other, thereby improving The reliability and stability of multi-channel ECG signal acquisition, this setting optimizes the management method of lead wire 7, avoids the problem of line entanglement or mutual interference, through the symmetrical setting of arc plate 1 509 and arc plate 2 510 in shape and height, the lead wire 7 can be evenly stressed when clamped, avoiding bias or tilting, thereby improving the firmness of clamping and the stability of contact, this setting effectively prevents signal interruption or data fluctuation caused by poor clamping, through the connection setting between through slot 3 511, the inner cavity of long rod 501, through slot 1 502 and the card slot 503, it is convenient for the lead wire 7 to be introduced from through slot 3 511, pass through the interior of long rod 501, and finally be clamped and fixed by arc plate 1 509 and arc plate 2 510, at the same time, this structure also provides path support for the sliding and clamping of the fixing block 506 in the through slot 1 502, this setting realizes the effective guidance and stable clamping of the lead wire 7, and improves the overall functionality and practicality of the device.
