311nm narrow-band NB-UVB therapy dermatological treatment lamp

Type:Uv phototherapy Time:2018-08-17 20:50:18 The NB-UVB therapy device with a wavelength of 320 nm to 290 nm is the most active part of the biological activity of UV light. The study found that UV light around 310 nm has the best therapeutic effect on skin diseases, and the erythema effect is relatively small. The combination of UVA or UVB does not enhance its efficacy, and it is more prone to erythema effect. Therefore, the wavelength of ultraviolet rays filtered by other wavelengths is 311 nm. The narrow-band UVB (NB-UVB) is produced and widely used in the treatment of skin diseases. At present, the domestic UVB medium-wave narrow-spectrum 311nm lamp can not be manufactured, the manufacturing process is complicated, and the quartz lamp has certain It is required that a certain special component is added to the lamp tube casing to block 300 or less, and ultraviolet rays of 320 or more are emitted. The special powder inside the tube emits ultraviolet light with a peak of 311 nm. The surface temperature of the lamp is 45 degrees to give maximum performance. The products of imported special lamps are narrow-band.

Indications:

1, psoriasis vulgaris, 2, vitiligo, 3, chronic eczema, 4, neurodermatitis, 5, atopic dermatitis, 6, palmoplantar pustulosis, 7, rose pityriasis, 8, alopecia areata, 9, Parapsoriasis, 10, chronic ulcers of the skin, 11, mycosis fungoides, 12, various light diseases.

The applicable population:

1. Patients who are inconvenient to come to the clinic on time;

2. Patients who require intensive treatment locally;

Treatment function:

1, improve the body's resistance and stress: by improving the sympathetic-adrenal system function, to regulate endocrine function and improve metabolism. Thereby enhancing the body's disease resistance and stress ability.

2, improve the body's immune function: can increase the formation of immunoglobulin in patients, can activate complement, so that white blood cells phagocytosis function.

3. Inhibition of epidermal cell proliferation: Ultraviolet light can reduce the synthesis of deoxynucleic acid which is proliferated too fast, thereby preventing the rate of cell sorting and proliferation.

4, damaged epidermal cells: after cell damage, can also release some chemicals, causing inflammation, so that the skin lesions gradually subsided.

5, improve the blood circulation of the skin: ultraviolet light can make the skin capillaries dilate, so that the blood flow is accelerated, so that the microcirculation bloody phenomenon

6. Stimulate the proliferation and migration of melanocytes. When melanocytes absorb UVB energy, they can stimulate the activity of tyrosinase, accelerate the oxidation and polymerization of tyrosine, increase the synthesis of melanin, and promote the release of keratinocytes. Factors that promote melanocyte proliferation and differentiation, such as endothelin-1, fibroblast growth factor, etc.; UVB has immunosuppressive effects; it can also accelerate local blood circulation, so that white spots disappear, so it can be used to treat vitiligo.

7, anti-inflammatory pain: can reduce inflammation, reduce the degree, reduce blister, reduce pain, can treat herpes zoster.

8, kill bacteria: both kill bacteria and improve local blood circulation, so that inflammation is limited, to a lesser extent. For the treatment of folliculitis, sputum, impetigo, erysipelas and so on.

9, promote wound healing: can reduce inflammation, reduce secretions, and promote the healing of sores.

10, improve the nutritional function of the nerve: local irradiation and cervical sympathetic nerve irradiation, can improve the nutritional function of the nerve, promote blood circulation, hair regeneration, can be used to treat alopecia areata.

Product features:

1. The therapeutic instrument adopts Philips narrow-spectrum UVB special medical light source, which is produced in Poland. This light source has passed the US FDA and European CE certification. It has high stability, long service life, pure light source, no pollution, safe and reliable use.

2, the device magnetic ballast, non-electronic rectification energy ratio, long service life. Small in size, placed in a travel bag, convenient for business trips, etc.

3. UVB ultraviolet light therapy tube has a good effect on the treatment of skin diseases such as vitiligo and psoriasis. It can improve the effect of the drug by 3 to 5 times. It is suitable for local patients, and patients can be treated under the guidance of a doctor in the hospital, or they can bring back their own treatment.

4. The light source adopts the medium-wave narrow-spectrum 311nm imported nb-uvb Philips ultraviolet lamp, which has high curative effect and small side effects; the control unit can ensure a sufficient amount of narrow-spectrum light waves, and the special circuit ensures that the temperature of the lamp tube is within a reasonable range to maximize the efficiency. Non-simple products can compare.

Product advantages:

1. The treatment course is short and the curative effect is fast, and the total effective rate is over 90%;

2, do not need to take other auxiliary drugs, to avoid the side effects caused by the use of photosensitizing drugs;

3, effective light output intensity, no light toxicity side effects, good safety and tolerance, no significant effect on normal skin; not easy to relapse after healing, better than single drug treatment.

4. Avoid the possibility of skin burns and carcinogenesis caused by traditional long-wave PUVA and broad-spectrum UVB.

Usage rules:

1. Confirmation of irradiation dose: According to the irradiation intensity of the phototherapy instrument, according to the formula: irradiation time = irradiation dose / irradiation intensity

Calculate the required irradiation time. Example: The irradiation intensity of the phototherapy instrument is E=5.6mw/cm. It is recommended that each dose be ��=0.3J (300mJ) and substituted into the above formula: 300��5.6=54 (seconds), the required time can be calculated. T = 54 seconds;

2. Turn on the power of the host and turn on the switch;

3, patients and operators are best to wear colored glass protective glasses.

4. According to the size of the lesion, cut the hole with the appropriate size of the lesion with paper or cotton cloth, cover the non-irradiated area, and expose the lesion. Place the irradiator on top of the affected area, turn on the power switch to illuminate, and after one part is finished, if it needs to be irradiated to other parts, move to other parts.

5. At the end of the irradiation, turn off the switch and disconnect the power supply;

6. It is best to stop the cosmetics during the irradiation period, and do not apply external medicine such as oil to the treatment site.

Time and frequency of exposure:

1. Continuous treatment should increase the dose (time) and the proportion of dose (time) increase each time according to the treatment frequency and treatment response:

a. If there is a slight erythema after the previous treatment and has subsided at the time of the treatment, it should be increased by 10% based on the previous dose or time;

b. If there is significant erythema after the previous treatment and it has not subsided during this treatment, the previous dose or time should be maintained;

c. If the erythema is still severe and accompanied by pain or even blisters during this treatment, treatment should be suspended;

d. If there is no treatment response after the previous exposure, you can increase the dose by 20% on the previous dose or time; for example, if your initial exposure time is 30 seconds and there is no treatment response after the irradiation, then you The second exposure time was 36 seconds.

2. How is the radiation frequency determined?

Narrow-spectrum UVB is irradiated 3 to 5 times per week.
