 Handisol • Narrowband UVB • 2-Lamp (Basic) & 4-Lamp (Premium) |
1. Device Overview
Handisol is a home phototherapy device for hands, feet, and localized areas, available in 2-lamp (Basic) and 4-lamp (Premium) models. It uses a Digital Timer (DT) controller for time-based treatments and comes with a stand for angled positioning.
2. Indications for Use
For physician-directed treatment of psoriasis and vitiligo. Federal law restricts this device to sale by, or on the order of, a physician (U.S.).
3. Warnings & Safety
- Prescription use only. Never treat more than once in 24 hours unless directed by a physician. Wear UV-blocking goggles during exposure.
- Cover all skin not being treated. Some medicines/cosmetics/foods increase photosensitivity (watch for redness 3–24 hrs post-treatment).
- Indoor use only (IPX0). Keep away from water; provide 4–6 in (10–15 cm) clearance for airflow.
- Use a grounded outlet; do not use 3-to-2 prong adapters. Unplug before cleaning or lamp replacement.
4. Site, Power & Setup
- Electrical: 120 VAC, 60 Hz, ~1.2 A; dedicated 15–20 A circuit recommended.

7. Treatment Protocols
A. Vitiligo (treat as Skin Type I)
- Distance: on window surface.
- Initial: 70% of MED; if MED unknown, start at 22 sec.
- Increase: +10% each session unless burning occurs. If light burning persists → reduce by 25%, then +5% per session once resolved.
- Frequency: 3×/week until re-pigmentation; maintenance typically begins when ≥75% re-pigmented.

8. Cleaning, Maintenance & Lamps
- Unplug first. Clean lamps/reflectors with a soft cloth and 70% isopropyl alcohol; do not use alcohol on clear plastic windows—use mild detergent/water.
- Lamp life: replace every 150–200 hours; replace all lamps together (mercury hazard—recycle responsibly; ventilate if broken).
- Keep vents clear; dust periodically. Do not overtighten stand knobs; hand-tighten only.

- Refill: give “CXXX” to your prescriber; they’ll generate a 4-digit Treatment Code (e.g., 0/75/100/250/unlimited exposures) to enter when prompted.
- Power loss mid-treatment: time isn’t remembered; one exposure may be deducted on exposure-limited units.
