Description

Textile type multi-channel high-sensitivity sensing dry electrode pads

The present invention relates to an electrode sheet for contacting with the body, which can receive or transmit electrophysiological signals, especially a dry patch for electrotherapy equipment, or an electrode sheet (patch) for measuring physiological signals.

It is known that there are common sports injuries, degeneration and other problems. In addition, the use of 3C electronic products leads to many bad postures, which cause physical pain, such as soreness, pain, numbness, etc. symptom. Once these symptoms occur, patients will first use patches, anti-inflammatory pain relievers, or massage to relieve pain. However, these methods may not be completely cured, so they will seek professional treatment from a physical therapist, or under the evaluation of a physical therapist, patients can purchase physical therapy equipment or equipment to use electrotherapy or thermotherapy by themselves.

These devices in electrotherapy or hyperthermia have a patch and a low frequency therapy device. After the low-frequency therapy device is electrically connected to the patch, the current generated by the low-frequency therapy device is transmitted to the patch, so that the electrodes on the patch can perform physical therapy on the sore place of the patient. Because the patch used for electrical signal transmission in the past has a water-rich layer (gel, hydrogel) for signal transmission, due to the capacitive effect of the water-rich layer, it is difficult to control the resistance. The reasons for the poor control mainly include the following:

1. The water glue is not easy to store and will dry up, resulting in inconsistent conductivity, and the difference between batches is not easy to control.

2. Artificial glue, the amount of glue is different each time, resulting in different impedance, thus affecting the measurement. Due to the above reasons, the signal will be saturated or distorted, and the subsequent software judgment may have errors or misjudgments.

3. Some high-frequency electrical stimulators or electrical signal transmitters will have a capacitive effect if they pass through the water-rich glue layer, causing delay and distortion, which will invalidate the therapeutic effect.

The main purpose of the present invention is to solve the traditional deficiencies. The present invention uses silver fiber cloth, nano-silver wire, and thermal transfer type conductive paste conductive paste. Various hot pressing and sewing methods, fixed on the electrode sheet, through the traction of the conductive cloth as a wire or a specific totem as an electrode, in order to improve the electrical signal transmission carrier (conductive cloth), and replace the water-rich wet electrode with a dry electrode The patch (patch) is used for the future electrocardiogram industry, electromyography rehabilitation industry, etc., to improve the measurement accuracy. As an electrical stimulation related industry, the transmission of electrical signals to the human body can be more accurate, so that the electrical stimulation system can transmit more accurate signals to the epidermis, muscles, and the human body, especially the muscle stimulation (EMS/ES) system can receive and measure more accurately. Measure the signal of muscle functional movement, and apply electrical stimulation with corresponding parameters to achieve the effect of rehabilitation; in the high-frequency electrical stimulation system, it can effectively transmit signals and energy, reduce distortion, and achieve better therapeutic effects.

To achieve the above purpose, the present invention provides a textile-type multi-channel high-sensitivity sensing dry electrode sheet, comprising: a main body, a conductive cloth and at least one electrode connection part. The body is a sheet-like body. The conductive cloth is attached to one side of the main body, and the conductive cloth has at least one electrode portion. The electrode connecting part is arranged on the main body and is electrically connected to the electrode part of the conductive cloth through the main body. Wherein, the electrode connecting part transmits the signal to the conductive cloth, so that the electrode part of the conductive cloth can produce the effect of electrotherapy or hyperthermia or both electrotherapy and hyperthermia simultaneously, and at the same time, the electrode part can receive electricity from the body through the electrode part. Physiological signals are sent back to the device through the electrode connection part.

In one embodiment of the present invention, an adhesive layer is provided on one side of the main body, and the adhesive layer and the conductive cloth are located on the same side of the main body.

In one embodiment of the present invention, the body is an OK stretcher.

Please refer to FIGS. 4 and 5 , which are the three-dimensional appearance of the second embodiment of the electrode sheet of the present invention and the schematic diagram of the outer surface of FIG. 4 . As shown in the figure: this embodiment is substantially the same as the first embodiment, the difference lies in that the conductive cloth 2 on the body 1 of the electrode sheet 10 is two-phase symmetrical and convex-shaped two electrode parts 21, where the electrodes are connected After the portion 3 passes through the body 1 , the electrode connecting portion 3 is electrically connected to the two electrode portions 21 respectively.
