Application of UV sensors in skin phototherapy devices

Ultraviolet light therapy is specially used to treat psoriasis and vitiligo. It is a physical therapy technique that uses ultraviolet rays to irradiate the human body to prevent and treat diseases. Ultraviolet light therapy is one of the effective methods for treating MF, especially early MF. Commonly used ultraviolet rays include PUVA, broad-spectrum medium-wave ultraviolet rays (BB-UVB) and NB-UVB. NB-UVB has been used in clinical practice since 1984, and was initially used mainly to treat psoriasis vulgaris. Its efficacy is significantly better than BB-UVB and is equivalent to that of PUVA, but with fewer adverse reactions.

Ultraviolet light therapy uses narrow-spectrum UVB technology with a wavelength of 311nm. Clinical trials have shown that narrow-spectrum medium-wave ultraviolet rays with a wavelength of about 311nm have significant therapeutic effects on skin diseases such as vitiligo and psoriasis, and are pure physical therapy. Ultraviolet light therapy can emit medium-wave ultraviolet rays with a wavelength of 311nm, which can be mostly absorbed by epidermal tissue, and thus have significant biological effects on skin and other tissues. Ultraviolet rays have good drying, bactericidal, and anti-inflammatory effects, and have a direct killing effect on bacteria or viruses in superficial tissues. They have the effects of accelerating blood circulation, relieving pain, and promoting epithelial regeneration. Therefore, ultraviolet irradiation therapy can directly kill herpes viruses, prevent secondary bacterial infections, promote blister absorption, relieve pain, and accelerate skin lesion repair and healing, thereby playing a good therapeutic role. Studies have also found that ultraviolet light therapy can significantly inhibit the activity of antigen-presenting cells such as epidermal Langerhans cells, reduce inflammatory reactions, improve local blood circulation, promote rash healing and relieve pain, etc., and have few adverse reactions and simple treatment.

The irradiation method of the ultraviolet light therapy device is handheld irradiation. Open the baffle of the base, take out the connecting line between the irradiator and the base, hold the irradiator, and aim the UV tube at the affected area. Fixed irradiation: insert the irradiator handle into the base slot, aim the UV tube at the affected area; if there are special circumstances during the care process, you must temporarily leave. When the irradiation treatment is over, the digital display will be "zero" and the lamp will automatically turn off. The entire irradiator treatment growth is over. If you want to use it again, you must start the whole procedure from the beginning. The time controller does not have the memory function of the last set irradiation time. If you finish using it, please turn off the power switch, unplug the power plug, clean and put it in the box.

Skin treatment: An important application of the UVB band is the treatment of skin diseases, that is, ultraviolet light therapy. Scientists have found that ultraviolet rays with a wavelength of about 310nm have a strong black spot effect on the skin, which can accelerate the metabolism of the skin and improve the growth of the skin, so that they can effectively treat vitiligo, pityriasis rosea, polymorphous light eruption, chronic actinic dermatitis, photo-induced prurigo and other light-induced skin diseases. Therefore, in the medical industry, ultraviolet light therapy is currently being used more and more. Compared with traditional light sources, the spectrum of UV-LED is pure, which can guarantee the treatment effect to the greatest extent. The UVB band can also be used in the field of health care. After exposure to the UVB band, it can cause photochemical and photoelectric reactions in the human body, causing the skin to produce a variety of active substances. It is currently used to regulate higher neural functions, improve sleep, and lower blood pressure. In addition, studies have shown that the UVB band can accelerate the production of polyphenols in certain leafy vegetables (such as red lettuce). These polyphenols are claimed to have anti-cancer, anti-cancer spread and anti-cancer mutation properties.

The UV phototherapy device is mainly composed of an irradiator, a base and a controller. Of course, a UV . Here, the editor recommends a UV sensor imported from abroad by Gongcai.com - GUVB-T11GD-L. The sensor has high sensitivity and good day blindness, peak response at 300nm band, TO-46 metal shell package, and large-area photosensitive chip. It is mainly used in UV index monitoring, UV-B lamp monitoring and skin medical fields.

Five features of ultraviolet light therapy device:

1. Small size, easy to carry;

2. The light source adopts medium-wave ultraviolet low-pressure fluorescent lamp tube, which has high efficacy and small side effects;

3. Unique irradiation structure design, large irradiation area, high irradiation intensity, and distance positioning;

4. The irradiator can be separated from the machine base, and the user can hold the lamp to conveniently irradiate any part of the body;

5. Equipped with a digital timer, the irradiation time can be conveniently set according to the patient's condition.
