Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0039] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.
[0040] refer to Figure 1 As shown, the present application provides a repetitive wet ECG electrode, which comprises in sequence: a conductive Velcro, a medical waterproof cloth, storage cotton, a one-way reverse osmosis cloth and a flexible electrode.
[0041] Among them, the conductive Velcro is connected to the flexible electrode through the fabric wire, and plays the role of a lead. The fabric wire, the conductive Velcro, the medical waterproof cloth, the storage cotton, the one-way reverse osmosis cloth and the flexible electrode are encapsulated into a whole by the support cloth. In this embodiment, since the support cloth has the characteristics of flexibility and elasticity, it can be used to prevent the electrodes from being pulled by the wearing clothes, or during exercise, it can keep the position between the ECG electrode and the wearing clothes stable, so as to avoid the relative position between the ECG electrode and the clothes being too large when pulling the clothes, resulting in excessive distortion of the measurement signal, and to avoid the problem of unstable quality of the ECG signal collected during exercise. In this embodiment, the support cloth is made of non-conductive material, which can prevent static electricity from burning the repetitive wet ECG electrode.
[0042] In this embodiment, the fabric conductor is made of conductive material, and is used to output the ECG signals captured by the flexible electrodes through the fabric conductor, such as outputting them to the conductive Velcro end, and then outputting them to the detection end through the conductive Velcro; for example, the ECG signals collected by the flexible electrodes are directly transmitted to the detection end through the fabric conductor.
[0043] In this embodiment, the conductive liquid is prevented from flowing to the conductive Velcro by the medical waterproof cloth, and the conductive liquid sequentially passes through the storage cotton and the one-way reverse osmosis cloth to penetrate into the flexible electrode, thereby achieving a wet electrode effect.
[0044] In an embodiment of the present application, the repetitive wet ECG electrode is fixed to the wearable garment by means of a conductive Velcro, and the flexible electrode of the repetitive wet ECG electrode is brought into contact with human skin through the wearable garment. In this embodiment, the conductive Velcro can also be replaced with a soft snap-on buckle or a nano-sticker to fix the repetitive wet ECG electrode on the wearable garment.
[0045] The medical waterproof cloth is arranged between the conductive Velcro and the storage cotton to prevent the conductive liquid stored in the storage cotton from leaking toward the conductive Velcro, or from continuing to leak toward the wearable clothes through the conductive Velcro.
[0046] The storage cotton achieves the function of storing the conductive liquid by absorbing the added conductive liquid. In the present embodiment, the storage cotton adds and stores the conductive liquid multiple times, so that the reusable wet ECG electrode can be used repeatedly.
[0047] The one-way reverse osmosis cloth is arranged between the storage cotton and the flexible electrode, and is used to infiltrate the conductive liquid stored in the storage cotton to the flexible electrode end, so as to prevent the sweat from infiltrating back to the storage cotton end when the flexible electrode contacts the skin. In this embodiment, the repetitive wet ECG electrode can ensure stable operation during exercise or high humidity environment through the one-way reverse osmosis cloth.
[0048] The flexible electrode is a silver fabric flexible electrode, which captures heart activity information by contacting the skin. The silver material can prevent sweat from corroding the flexible electrode, and has an anti-corrosion function. At the same time, since the silver fabric has antibacterial and antibacterial functions, the repetitive wet ECG electrode reduces skin irritation and infection risks during use. In this embodiment, the number of cleaning times of the flexible electrode meets the standard requirements for fabric cleaning times.
[0049] In this embodiment, the present application also provides a method for using a repetitive wet ECG electrode, specifically comprising:
[0050] The electrodes are attached to the electrocardiogram wearable clothing by means of the conductive Velcro on the electrodes;
[0051] The flexible electrodes on the electrodes are brought into contact with human skin by transmitting to the electrocardiogram clothing;
[0052] The ECG information collected by the flexible electrodes is output through the fabric wires on the electrodes.
[0053] In summary, the repetitive wet ECG electrode provided by the present application has the following advantages:
[0054] 1. Multi-purpose: support one-time use or reuse after cleaning.
[0055] 2. User-Friendliness: Adopts flexible silver fabric material to ensure comfortable wearing and suitable for different skin types.
[0056] 3. Cleanable electrodes: easy to install and remove the wearable garment, and the wearable garment and electrodes can be easily cleaned and washed in different ways.
[0057] 4. The output quality of the measured VSM (vital signs) signal is stable and no intervention is required.
[0058] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described.
