Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, in particular to the technical field of medical safe use of air cold plasma devices. Background Art

[0002] Plasma is the fourth state of matter after solid, liquid and gas. 99.999% of the matter in the universe belongs to plasma. Devices developed based on cold air plasma under atmospheric pressure mostly use dielectric barrier discharge technology. Its main principle is to ionize the gas through a high voltage electric field to release active substances such as active oxygen and active nitrogen, thereby preventing and treating various skin diseases or skin beauty.

[0003] Atmospheric pressure air cold plasma technology is a non-contact plasma technology. It uses the effect of high voltage electric field to convert gas into plasma, and then produces active substances such as ions, free radicals, and electrons with a certain energy to treat the target substance, which can kill bacteria, stimulate skin metabolism, promote skin regeneration, and achieve the effect of treating the skin. Atmospheric pressure air cold plasma technology is widely used. In addition to industries such as skin trauma treatment, it is also used in air purification, water treatment, material surface treatment and other fields.

[0004] The air cold plasma device has the following technical features. First, it is non-invasive. Traditional technologies usually require drug treatment, which is highly irritating to the skin, or require invasive operations such as injections and surgical resections. Atmospheric pressure air cold plasma can be used for treatment without damaging the skin, avoiding surgical trauma and pain and discomfort during treatment. Third, plasma technology is also very safe. No chemical agents or laser instruments are required during the treatment process, so many adverse reactions and side effects associated with traditional chemical agents and laser treatments can be avoided.

[0005] The basic components of existing air cold plasma generating devices include a main unit and a handle. The handle mainly carries the discharge electrode. When high voltage is applied to metal electrodes of different forms, the gas between the electrodes will be ionized by the electric field to form cold plasma containing a large amount of active substances, which will be ejected from the handle to treat the skin surface. In the development of modern technology, air cold plasma devices have excellent prospects and application value, providing a new choice to better meet people's needs for beauty and health.

[0006] However, some existing air cold plasmas have a high temperature at the front end of the handle. If the distance between the port and the skin is not properly controlled, it is easy to cause burns to the skin. At the same time, the front end electrode of the handle is also prone to strong discharge to the skin, which brings unsafe factors. Summary of the invention
