Technical Field

The invention relates to the field of medical instruments and health care instruments, in particular to an electrode pad with a moisture absorption structure applied to human skin.

Background

The application of electric fields and currents in the medical field has been known for many years and is mainly in two forms: 1) the conductive electrode is applied to a human body or an animal body, a certain potential difference is kept, and an electric field is formed by applying the conductive electrode to the body or tissue. The application mode can be applied to the surface of the skin of a human body or in the human body, such as a cardiac defibrillator, a peripheral nerve and muscle stimulator, a tumor resection device and the like; 2) electric wave sources emit electric waves, such as RF wave sources and microwave sources, which deliver energy to the body by radiation or induction. In this mode, there is no electrical energy conduction between the energy source and the body.

The tumor treating electric field is one low strength, medium frequency and alternating electric field and can treat tumor via interfering the mitosis process of tumor cell. Research shows that the tumor electric field treatment method has obvious effect in treating tumors such as glioblastoma, non-small cell lung cancer, melanoma and the like, can prolong the life of a patient, and has small side effect.

The tumor treatment electric field is applied to the tissue region where the tumor is located through an external electrode, and the electric field is applied to the tumor in a capacitive coupling mode. The electric field electrode for treating tumor is applied to the skin surface of a patient to treat the patient for a long time, and the continuous application time of the electric field electrode is 2-4 days. After long-term treatment, the sweat gland and hair follicle of the skin can be blocked, and the evaporated sweat can cause the reaction of allergy, red swelling and the like. Therefore, it is necessary to absorb or remove sweat discharged from the skin, thereby avoiding adverse reactions such as skin allergy and red swelling.

The invention patent CN111759359A discloses a multichannel fiber-based sweat collection and sensing system and a preparation method thereof. The sweat sensing system is a multilayer fabric, the inner layer of the sweat sensing system comprises a multi-channel fiber-based sweat collection system and a gate electrode, and the outer layer is provided with a source electrode and a drain electrode. The sweat collection system comprises a plurality of sweat transmission channels and hydrophobic areas which are distributed at intervals and are collected in the sweat collection area; each sweat transmission channel is provided with a plurality of hydrophilic and hydrophobic gradient units with contact angles gradually increasing from the outside close to the sweat collection area, and the textile weave structure of the hydrophilic and hydrophobic gradient units is regulated to form a sweat collection system with a self-driven wicking effect, so that sweat is directionally transmitted from the outside to the sweat collection area through the hydrophilic and hydrophobic gradient units. The sensor signal amplification efficiency is high, and therefore the sensitivity and the detection rate of sweat detection are improved. However, this patent is mainly used for sweat collection and then testing the collected sweat, but does not disclose an electrode for applying an electric field to a living body, nor is it used for eliminating or effectively reducing side effects caused by long-term application of an electric field to human skin.

The statements in the background section are merely prior art as they are known to the inventors and do not, of course, represent prior art in the field.
