SIGMA 308nm Excimer Laser Excimer Light XECL Lamp for Vitiligo Psoriasis UVB Phototherapy Lamp Psoriasis Treatment Device

“Instructions:
308nm excimer light machine SH308 is designed for clinic and household use.   Dermatologists and patients can purchase this unit for UVB phototherapy treatment of vitiligo, psoriasis and other skin diseases.   For those clients who need only a few seconds for a single irradiation on the face, limbs, trunk and other parts with fast blood circulation, clinical cure can be achieved without the additional purchase of timer card.
Application:Applicable Places: hospitals, clinics and household.
Applicable Skin Diseases:
-Vitiligo: Monochromatic UVB light is an effective approach for the treatment of vitiligo with few side effects.   SIGMA 308nm excimer system SH308 gets results in vitiligo treatments that match those of a laser.
-Psoriasis: With high power density and focused lesion targeting, 308nm excimer light is an outstanding treatment solution for therapy of localized, persistent psoriasis plaques on the elbows, knees, hands, feet and scalp.   Research results: 81% patients obtain over 74% elimination rate in less than 10 times treatment;   55% patients obtain over 92% efficacy in less than 10 times treatment.
-Generalized&chronic eczema and all kinds of dermatitis: seborrheic dermatitis, atopic dermatitis, allergic dermatitis and other dermatitis
-Alopecia areata, mycosis fungoides, pityriasis rosea, erythema anulare centrifugum (EAC), urticaria, skin pruritus etc.

Features:
308nm Excimer Principle
1.  The light source is molecules formed by xenon atoms (Xe) and chlorine atom (Cl) under the action of high frequency electric field.
2.  Since the chlorine atoms (Cl) can accept an electron from xenon atom, the two atoms are in an unstable electron configuration(excimer) after being excited and will strive to come back to its original form, resulting in a high purity 308nm monochromatic excimer light.
3.308nm excimer light is in the middle wavelength of 290~320nm, also the most effective wave band, which can enhance the activity of tyrosinase in melanocytes to produce melanin quickly in melanocytes, thus the effect of the treatment is achieved.

Product Features
1. 308nm single wavelength excimer light output via the medium XeCl
– SH308 is the only 308nm excimer light product that has the same peak wavelength and error as 308nm laser(308nm±1nm). Other product: 308nm ±2nm
2. High radiation intensity, highly effective and fast results
– High radiation intensity makes SH308 outstanding for medical treatment in the clinic/hospital and as the portable treatment for home phototherapy.
3. Targeted treatments, maximum protection of healthy skin
– Single light spectrum: 308nm UV light can be effective to the skin leisions. It will not affect the healthy skin.
4. Up to 22.09cm2 spot size for short treatment times of larger areas, fast treatment
– Large radiation window (4.7cm*4.7cm) can cover more skin lesion in each treatment. Patients and medical staff can save more treatment time.
5. Multiple spot sized output windows to meet different body parts treatment demand in clinic practice
– There are 4 covering pads in the box. Patients and medical staff can choose the suitable one to expose the targeted lesions and cover the healthy skin. You can DIY the pad according to the skin lesion shape.
6. No replacement consumables, low maintenance cost
– SH308 has no timer card. Patients and medical institutions can use it for a long time, even for years. One purchase, no extra cost. SH308 is designed for trouble-free operation.  has excellent after-sales service team. We will guide you how to use the device and do the product care and maintenance.
7. User- friendly Interface, convenient and easy to operate
– SH308 uses radiation time setting mode. Only 3 steps: 1.Switch on; 2.Set radiation time; 3.Start treatment. Very easy to use.
8. Handheld designed excimer system, mobile for therapy
– SH308 is a portable and handheld device. Light weight (1.60Kg) to hold. Much lighter than other products on the market.
Use Method
Treatment Frequency: Every second day
Recommended initial radiation time: Vitiligo:3s; Psoriasis: 6s

Preparations before therapy
1. Clean the skin lesions.
2. Set radiation time.
3. Wear UV goggles. Warm Prompt If the skin lesions are on/around the areola genital area, please lessen the radiation time and consult the doctor! Observation After Therapy: Skin reactions generally occur 4-10 hours after phototherapy.
Radiation time adjustment: Increment and decrement 1. No erythema: Increase time by 20%. Minimal increment: 3s. 2. Slight erythema, fade within a few hours: Increase time by 10%. Minimal increment: 3s. 3. Obvious erythema: Keep the same time of the previous treatment. 4. Obvious erythema with peeling skin: Stop treatment. After recovery, reduce time by 20%. 5. Serve erythema with pain/swelling: Stop treatment. After recovery, reduce time by 50%. 6. Serve erythema with blister: Stop treatment. After recovery, reduce the time by 50%. Please go to the hospital to treat the blisters to avoid infection.
