What Is Psoriasis Light Therapy?

Ultraviolet phototherapy instrument specializes in psoriasis and vitiligo. It is a physical therapy technology that uses ultraviolet rays to irradiate the human body to prevent and treat diseases. Ultraviolet phototherapy is one of the effective methods to treat MF, especially early MF. Commonly used ultraviolet rays include PUVA, broad-spectrum medium-wave ultraviolet (BB-UVB), and NB-UVB. Since 1984, NB-UVB has been used in the clinic. It was mainly used for the treatment of psoriasis vulgaris, and its efficacy was significantly better than BB-UVB. It was equivalent to PUVA, but with less adverse reactions.

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

Ultraviolet light therapy instrument is suitable for some middle-aged and young office workers who can't get medical treatment on time. Special groups with limited mobility and unable to go to hospital for treatment on their own; patients in remote areas, with inconvenient transportation, who go to hospital for treatment is time-consuming and expensive. It has obvious therapeutic effect on patients with psoriasis and psoriasis.

Ultraviolet phototherapy instrument is also suitable for some patients who are being treated in the hospital, but some affected areas need to be strengthened; patients who need to be treated in a small area; patients who need to ensure corresponding privacy; patients who have a large work mobility and need to carry the treatment with them. For this group of people can use ultraviolet phototherapy equipment.

Psoriasis vulgaris, vitiligo, chronic eczema, neurodermatitis, atopic dermatitis, palmar plantar impetigo, pityriasis rosea, alopecia areata, parapsoriatic, chronic skin ulcers, mycosis fungoides, various light Illness.

Working environment conditions: the temperature should be between 10 30 ; keep it clean and the relative humidity should be less than or equal to 75%; the atmospheric pressure should be between 860hpa and 1060hpa; power supply: AC 220V ± 10%, 50Hz ± 1Hz; Use in a relatively dry room and avoid direct sunlight.

Maintenance, cleaning and storage: First of all, UV lamps and reflective components, limit rods, etc. should be cleaned regularly without leaving traces or fingerprints. Keep the irradiator in good working condition to ensure the effect of irradiation. Secondly, the irradiator should not be dusty and the humidity is too high. Please use antistatic cleaners for surface cleaning, and maintain regular cleaning and maintenance. The irradiator is then an ultraviolet light source and does not require disinfection. Also, the irradiator should be used in a relatively dry room and protected from sunlight.

Finally, the irradiator is not used for a long time. Please clean and maintain the irradiator and put it in the box.

Storage environment requirements: temperature: -40 + 55 ; relative humidity: 93%; no water, no corrosive gas, and good ventilation.

For users who use it frequently, it is recommended that you replace the lamp after the cumulative usage time of the lamp reaches 500 hours.

The domestic ultraviolet therapeutic instrument uses long-wave ultraviolet low-pressure fluorescent tube, which has high curative effect, no side effects, large irradiation area and high irradiation intensity. It has a good curative effect on the treatment of skin diseases such as vitiligo and psoriasis. The home-use ultraviolet therapeutic apparatus enables patients to enjoy the same treatment effect in the hospital without leaving home.

The popularity of household ultraviolet therapeutic instruments is getting higher and higher, bringing convenience to patients. The home ultraviolet therapeutic apparatus is the first choice for home phototherapy equipment. With the large-scale promotion of the reform of China's medical system, more and more patients choose to treat at home, so more and more patients purchase home ultraviolet treatment instruments.

UV Phototherapy Device Basic Information

Ultraviolet phototherapy device is currently the world's most advanced skin phototherapy method. It uses a narrow-spectrum medium-wave ultraviolet light with a peak value of 311nm. It concentrates the most biologically active part of ultraviolet light and directly affects the affected area of the skin. Ultraviolet rays have little side effects, and it acts on the stratum corneum of the skin. Is currently the most commonly used method of treatment of vitiligo abroad.

Ultraviolet phototherapy instrument, authoritative, efficient, convenient and economical. Efficient, many years of marketing experience, has a significant effect on psoriasis, vitiligo, chronic eczema, and neurodermatitis. Convenient and economical, dexterous and lightweight to use, local irradiation is more handy, economical, and you can enjoy the same professional curative effect at home for only one course of hospital outpatient expenses ^[2] .

Features of UV Phototherapy Apparatus

(1) Small size and easy to carry;

(2) The light source uses medium-wave ultraviolet low-pressure fluorescent lamps, which has high curative effect and small side effects;

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

(4) The irradiator can be detached from the machine base, and the user can easily illuminate any part of the body by holding the lamp;

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

UV light therapy instrument initial exposure time

Phototherapy experts recommend that the skin type of the Chinese population is mostly to . The initial dose of narrow-spectrum UVB in patients with psoriasis is 0.3J / cm2, and the initial dose of PUVA therapy is 2J / cm2; narrow-spectrum UVB in patients with vitiligo The initial radiation dose was 0.2 J / cm2, and the initial radiation dose for PUVA therapy was 1.0 J / cm2. Due to the large differences between individuals, please consult your doctor for precise dose determination.

After the initial irradiation dose is determined, it can be based on the local irradiation intensity value marked on the base of the home-use ultraviolet phototherapy apparatus and the "irradiation time calculation method" in the appendix of the instruction manual or according to the "irradiation dose / intensity / time reference table" Determine the corresponding initial irradiation time.

UV phototherapy instrument increasing time

Whether to increase the radiation dose (time) and the proportion of the dose (time) increase with each continuous treatment should be determined according to the frequency of treatment and response to treatment. If a slight erythema appears after the previous treatment and has subsided at the time of this treatment, it should be increased by 10% from the previous dose or time. If significant erythema appears after the previous treatment and has not subsided at the time of this treatment, the previous dose or time of exposure should be maintained. If erythema is still severe with pain or even blisters at the time of this treatment, treatment should be suspended. If there is no treatment response after the previous irradiation, it can be increased based on the previous irradiation dose or time.
