Description

light therapy device

technical field

The utility model relates to a treatment device, in particular to a phototherapy device.

Background technique

Phototherapy uses appropriate light sources, such as LEDs (Light Emmitting Diodes), which can provide some energy to the patient's body in the visible and infrared ranges. The body will absorb photons through the skin, acupuncture points or meridians, and the connected tissues inside the body will Light guides to deeper tissues or organs. Appropriate wavelengths of light can be transmitted, absorbed, and utilized by the body to activate the body's metabolic functions.

The light source of LEDs "Light Emitting Diode" can improve the treatment of skin aging and youth. LEDs use the concept of "phytodynamic therapy" (PDT) to lightly treat the skin with low-power LEDs arranged in a matrix-sized area to achieve the effects of fine skin, small pores, postoperative swelling improvement, and acne treatment. This therapy was used in patients with skin cancer or oral cancer in the early days. In recent years, diodes combined with gallium, arsenic, and aluminum groups emit red light with a wavelength of 633nm to stimulate the cytochrome of fibroblasts to facilitate the production of collagen, so it is effective for fine lines. , Large capillary pores, postoperative swelling have a good effect. The wavelength of blue light is 413nm, which is absorbed by the rhodopsin of acne bacteria, destroys and sterilizes.

In short, various light sources have a certain degree of influence on the human body. For example, red light, such as the red light of dynamic light, can penetrate deeper and activate cells, so red light of a specific wavelength can have anti-inflammatory effects. In the beauty industry, the red light irradiation system is mostly used for light SPA, eliminating dullness, revitalizing the skin, eliminating acne, dark spots, etc. Blue light, such as the blue light of dynamic light and ClearLight, has shallow penetration. Therefore, blue light of a specific wavelength has an impact on bacteria that cause inflammation, and it will block or cause the chemical reaction of specific chemical substances in the bacteria to achieve a bactericidal effect. It is clinically effective for superficial inflammatory acne, such as small red hot acne or small pustules. Medical red and blue light irradiation systems are mostly used to promote drug absorption and sterilize and reduce inflammation. And the rest of the various lights also have their special uses.

Inflammation of the human body is mainly caused by bacterial infection and human secretion. Irradiation with light sources of various colors and specific wavelengths has been clinically proven to have anti-inflammatory and bactericidal functions. Treatment of the body with light must have the choice of several important parameters, including the wavelength range, the relative wavelength distribution (spectrum) in a specific range, the time interval between consecutive exposures, the time interval between two consecutive exposures, the energy Rate of delivery, cumulative energy density of exposure, body parts irradiated, and other items.

Although currently on the market, there are smaller medical devices for anti-inflammation and skin treatment, such as light nose devices. However, the medical light source devices used in other clinical treatments or beauty salons are too bulky, consume a lot of power, and their high prices make ordinary people unable to afford the required devices for self-treatment of mild inflammation at home. And generally speaking, during medical treatment, the patient must be in a fixed position and cannot do other things. But at home, people generally want to watch TV or perform other activities, and larger devices cause considerable inconvenience. Furthermore, the average course of treatment is usually as long as 2-3 months. Even for the treatment of acne, patients need to go to and from the hospital many times, which consumes a lot of power and time.

Therefore, it is necessary to provide a patch-type phototherapy device that combines optical design, circuit design and appropriate transparent materials, allowing patients to stick a therapeutic device with a specific wavelength on their body or face.
