[0035] In related technologies, electrocardiographs (ECGs) record bioelectrical signals through the lead electrodes of the lead assembly. Taking the chest leads as an example, a typical chest lead assembly includes six chest lead electrodes, which need to be fixed to specific positions on the chest during ECG testing. Currently, each chest lead electrode is generally connected to a lead wire, which connects to the ECG machine's main unit. In this approach, the multiple lead wires are prone to tangling and knotting during use and storage, and each chest lead electrode needs to be individually fixed to the chest after untangling the lead wires, making it inconvenient to use.

[0036] This utility model proposes a lead assembly 100 and an electrocardiograph.

[0037] Please see Figures 1 to 2 In one embodiment of this utility model, the lead assembly 100 includes:

[0038] Several chest lead electrodes 11 are used for connection to the human chest; and

[0039] A flexible fixing member 12 is provided, and a plurality of the chest lead electrodes 11 are spaced apart on the flexible fixing member 12. The flexible fixing member 12 is deformable and can be used to change the connection position of the chest lead electrodes 11.

[0040] In some embodiments, the flexible fixation member 12 has a certain degree of elasticity and flexibility, and can be deformed by means of bending or stretching to change the connection position between the chest lead electrode 11 disposed on the flexible fixation member 12 and the human body. The chest lead electrode 11 includes an elastic adsorption member and an electrode. When the chest lead electrode 11 is adjusted to the correct position, the electrode can be adsorbed and fixed to the skin of the human chest by the suction force of the elastic adsorption member.

[0041] The lead assembly 100 of this utility model, by sequentially and spacedly arranging a plurality of chest lead electrodes 11 on a flexible fixing member 12, enables multiple chest lead wires 13 to maintain an orderly arrangement. Furthermore, by making the flexible fixing member 12 deformable, the lead assembly 100, during use, only requires adjusting the shape of the flexible fixing member 12 to fix each chest lead electrode 11 on the flexible fixing member 12 to a specific position on the human chest, avoiding the risk of disordered arrangement of the chest lead electrodes 11 affecting the normal use of the electrocardiograph, thereby improving the ease of use of the lead assembly 100.

[0042] Please see Figure 2 In an embodiment of this utility model, the flexible fixing member 12 is provided with a guide rail 121, and a plurality of the chest lead electrodes 11 are slidably disposed on the guide rail 121.

[0043] Thus, the chest lead electrode 11 can be adjusted in its connection position with the human chest by sliding on the guide rail 121 within the flexible fixation member 12 through the sliding engagement of the guide rail 121. The guide rail 121 can be formed by two opposing semi-rail structures, or it can be formed by a groove structure in the flexible fixation member 12. No limitation is made here.

[0044] It is understandable that due to differences in body shape among individuals, the positions of the various chest lead electrodes 11 will differ when using the lead assembly 100 for testing. Therefore, the technical solution of this utility model, by making the chest lead electrodes 11 slidable, allows the position of the chest lead electrodes 11 on the flexible fixation member 12 to be adjusted according to each person's chest size. This makes the lead assembly 100 suitable for different individuals after adjusting the chest lead electrodes 11, thus improving the practicality and applicability of the lead assembly 100.

[0045] Furthermore, in some embodiments, the chest lead 10 may also include several fixing structures, each corresponding to a chest lead electrode 11, for fixing the moved chest lead electrode 11 and the flexible fixing member 12 together to prevent the chest lead electrode 11 from shifting during use after adjustment. The fixing structure may be, but is not limited to, a snap-fit ​​structure.

[0046] In an embodiment of this utility model, the flexible fixing member 12 further includes a potential connection groove, which is disposed on the guide rail 121 for electrical connection with the chest lead electrode 11.

[0047] With this configuration, the electrical connection between the chest lead electrode 11 and the chest lead wire 13 can be achieved through the potential connection slot.

[0048] In some embodiments, the potential connection groove can be extended along the length of the guide rail 121 so that it remains connected and engaged with the chest lead electrode 11 when the chest lead electrode 11 slides relative to the guide rail 121, thereby enabling the chest lead electrode 11 to have a potential at any position it moves to.

[0049] In an embodiment of this utility model, the guide rail 121 includes a plurality of partitions, which are spaced apart from the flexible fixing member 12.

[0050] Each of the aforementioned separators is located between two adjacent chest lead electrodes 11.

[0051] The separator can be, but is not limited to, a resistive barrier. By setting a separator between two adjacent chest electrodes and fixing the separator and the flexible fastener 12, the maximum travel of the chest lead electrode 11 can be limited by the separator.

[0052] Please see Figure 3 In an embodiment of this utility model, the flexible fastener 12 includes a plurality of connecting portions 122 arranged sequentially along its length direction, and adjacent connecting portions 122 are detachably connected.

[0053] Each of the connecting portions 122 is provided with at least one of the chest conduction electrodes 11.

[0054] Thus, when the flexible fastener 12 is set as a whole and is not convenient to be fixed to a specific position on the chest of the human body, the different parts of the flexible fastener 12 can be separated and fixed to different parts of the human body by disassembling the two adjacent connecting parts 122; after use, the different parts of the flexible fastener 12 can be reassembled as a whole for storage, thereby further improving the ease of use and applicability of the guide assembly 100.

[0055] The two adjacent connecting parts 122 can be detachably connected by means of, but not limited to, snap-fit ​​connection, magnetic connection, etc. For example, one of the two adjacent connecting parts 122 is provided with a slot, and the other is provided with a snap-fit, which can engage with the slot. In this way, different parts of the flexible fastener 12 can be connected or separated according to the usage requirements.

[0056] Specifically, in one optional embodiment, the lead assembly is configured with twelve leads. In this case, the flexible fixation member 12 can be set as a single piece. The lead assembly also includes six unipolar chest leads, and the six chest lead electrodes 11 can be arranged side by side on the flexible fixation member 12.

[0057] Furthermore, the lead assembly 100 can also be configured with eighteen leads. Compared to a twelve-lead ECG, the eighteen-lead ECG adds six leads to the twelve-lead configuration, specifically three right precordial leads and three left posterior wall leads. Specifically, the flexible fixation member 12 includes three connecting parts: one connecting part has six unipolar precordial leads arranged side-by-side, another connecting part has three right precordial leads arranged side-by-side, and the last connecting part has three left posterior wall leads arranged side-by-side. In use, the three connecting parts 122 can be separated to be fixed to corresponding positions on the chest and back of the body. This increases the applicability of the lead assembly.

[0058] Please see Figure 1 In an embodiment of this utility model, the chest lead 10 further includes at least one chest lead wire 13, one end of which is electrically connected to at least a portion of the plurality of chest lead electrodes 11, and the other end is used to connect to the host.

[0059] Thus, with the flexible fixation component 12 as a single unit, several chest lead electrodes 11 on the flexible fixation component 12 can be connected by a single chest lead wire 13, so that the electrical signals collected by the lead assembly 100 can be transmitted to the main unit of the electrocardiograph via a single chest lead wire 13. This simplifies the number of cables in the lead assembly 100 and helps to avoid the risk of the cables of the lead assembly 100 becoming tangled and knotted during use and storage, thereby improving the ease of use of the lead assembly 100.

[0060] Further, please refer to Figure 3 Given that the flexible fastener has several connecting parts, several chest lead wires 13 can be set. One end of each chest lead wire 13 is used to electrically connect all the chest lead electrodes 11 on each connecting part 122, and the other end is used to connect to the host.

[0061] In an embodiment of this utility model, the chest lead wire 13 includes:

[0062] A first bus is used to connect the host; and

[0063] A plurality of first branch lines are connected to one end of the first bus, and each first branch line corresponds to one of the chest lead electrodes 11.

[0064] Specifically, a total of six chest lead electrodes 11 are provided, and one end of the chest lead 13 is formed by six first branches. In this way, the electrical signals of the six chest lead electrodes 11 can be transmitted through the six first branches respectively, and the six first branches can be connected to the electrocardiogram host through a first bus.

[0065] Please see Figure 1In an embodiment of this utility model, the lead assembly 100 further includes a limb lead 20, the limb lead 20 comprising:

[0066] Several of the aforementioned limb lead electrodes 21 are used for connection to human limbs; and

[0067] The limb lead wire 22 has one end electrically connected to a plurality of limb lead electrodes 21, and the other end is used to connect to the host.

[0068] In this way, several limb lead electrodes 21 can be connected through a single limb lead wire 22, so that the electrical signals collected by the lead assembly 100 can be transmitted to the main unit of the electrocardiograph via a single limb lead wire 22. This simplifies the number of cables in the lead assembly 100 and helps to avoid the risk of the cables of the lead assembly 100 becoming tangled and knotted during use and storage, thereby improving the ease of use of the lead assembly 100.

[0069] Specifically, in some embodiments, the lead assembly 100 includes two limb leads 20, namely an upper limb lead 20 and a lower limb lead 20. Each limb lead 20 includes two limb lead electrodes 21. With this configuration, the lead assembly 100 can simplify the number of cables to three. The limb leads 20 can be configured as clamp-type limb leads 20, and the limb lead electrodes 21 can be configured as electrode clips.

[0070] In an embodiment of this utility model, the limb lead cable 22 includes

[0071] The second bus is used to connect the host; and

[0072] A plurality of second branch lines are connected to one end of the second bus, and each second branch line corresponds to one of the limb lead electrodes 21.

[0073] Specifically, two limb lead electrodes 21 are provided. One end of the limb lead wire 22 is formed by two first branches. In this way, the electrical signals of the two limb lead electrodes 21 can be transmitted through the two second branches respectively, and the two second branches can be connected to the electrocardiogram host through a second bus.

[0074] Of course, the technical solution of this utility model is not limited thereto. In the embodiments of this utility model, a plurality of the limb lead electrodes 21 are arranged at intervals along the length direction of the limb lead line 22 to be connected in series with the limb lead line 22.

[0075] Specifically, two limb lead electrodes 21 are provided, and a single limb lead wire 22 is connected in series with the two limb lead electrodes 21. In this way, the branch structure of the limb lead wire 22 can be reduced, which helps to reduce the risk of the cables of the lead assembly 100 becoming tangled and knotted during use and storage, thereby improving the ease of use of the lead assembly 100.

[0076] This utility model also proposes an electrocardiograph (ECG) machine, which includes a main unit and a lead assembly 100. The specific structure of the lead assembly 100 is as described in the above embodiments. Since this ECG machine adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
