Ultraviolet phototherapy instrument specializes in 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 to treat MF, especially early MF. Commonly used ultraviolet rays include PUVA, broadband ultraviolet (BB-UVB) and NB-UVB. NB-UVB began to be used in clinical practice in 1984, initially mainly used for the treatment of psoriasis vulgaris. Its curative effect is significantly better than that of BB-UVB, which is equivalent to that of PUVA, but with less adverse reactions.
The ultraviolet phototherapy instrument uses narrow-band UVB technology with a wavelength of 311nm. Clinical trials have proved that narrow-band medium-wave ultraviolet rays with a wavelength of about 311nm have significant effects on the treatment of skin diseases such as vitiligo and psoriasis, and belong to pure physical therapy. The ultraviolet light therapy instrument can emit medium-wave ultraviolet rays with a wavelength of 311nm. Most of the ultraviolet rays of this wavelength can be absorbed by epidermal tissues, so it has a significant biological effect on skin and other tissues. Ultraviolet rays have good drying, sterilizing and anti-inflammatory effects, and have direct killing effects on bacteria or viruses in superficial tissues, and have the effects of accelerating blood circulation, analgesia, and promoting epithelial regeneration. Therefore, ultraviolet radiation treatment can directly kill herpes viruses Prevent secondary bacterial infection, promote blister absorption, relieve pain, accelerate skin lesion repair and healing, and play a good therapeutic effect. The study also found that ultraviolet phototherapy can significantly inhibit the activity of epidermal Langerhans cells and other antigen-presenting cells, reduce inflammation, improve local blood circulation, promote skin rash healing and relieve pain, etc., and have fewer adverse reactions and simple treatment .
The irradiation method of the ultraviolet phototherapy apparatus is to irradiate by hand, open the baffle of the base, take out the connection line between the irradiator and the base, hold the irradiator, and aim the UV tube at the affected area. Fixed irradiation: Insert the handle of the irradiator into the base slot, and aim the UV tube at the affected area; temporarily leave it in case of special circumstances during the care. After the irradiation treatment is over, the digital display is "zero", and the lamp is automatically turned off. The treatment growth of the entire irradiator is over. If you want to use it again, the entire program must be started from the beginning. The time controller has no memory function for setting the irradiation time last time. If you are finished using it, turn off the power switch, pull out the power plug, clean it and put it in the box.
Skin treatment: An important application of the UVB band is the treatment of skin diseases, that is, the application of ultraviolet light therapy. Scientists have found that ultraviolet rays with a wavelength of about 310nm have a strong dark spot effect on the skin, which can accelerate skin metabolism and increase skin growth, which can effectively treat vitiligo, pityriasis rosea, polymorphic sun eruption, and chronic actinic dermatitis. Photogenic skin diseases such as prurigo, light prurigo, etc. Therefore, in the medical industry, ultraviolet light therapy is currently more and more used. 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. The UVB band can cause photochemical and photoelectric reactions of the human body and produce a variety of active substances in the skin. It is currently used to regulate advanced nerve 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 ultraviolet phototherapy instrument is mainly composed of an irradiator, a base and a controller. Of course, an ultraviolet sensor is also applied. Here, the editor recommends an ultraviolet sensor imported by Gongcai.com from abroad-GUVB-T11GD-L, the sensor It has high sensitivity and good solar blindness, peak response at 300nm band, TO-46 metal shell package, large area photosensitive chip. Mainly used in UV index monitoring, UV-B lamp monitoring and skin medical field.
