Abstract
A hand-held ultraviolet germicidal system, pen light sized. Includes an ultraviolet lamp that is enclosed in a quartz cover operated by ballast circuitry, which is powered by batteries that incorporates a timing circuit and a safety circuit. The circuitry that is powered by batteries operates a ballast which powers a UV lamp, only after the continuity of an adult hand is sensed. The unit is then held over the target area for a predetermined time for the results.
Claims6
A method of treating onychomycosis by disinfecting human nails. This method includes the steps of:
- Directing the UV light source and associated UV transmissive cover that extends from the first end of the system at the area of the body to be disinfected;
- Sensing that the unit is held by an adult hand;
- Turning the light source on to emit UV radiation in the 254 nm range directed at the area to be disinfected.
The method of claim i further includes the step of turning the light source off at a predetermined time after the light source is turned on.
A hand-held UV germicidal system comprising:
- A UV light source;
- A UV transmissive cover that fits over the light source;
- A reflective cover to direct the UV light;
- Power means for supplying power to the light source;
- and
- A case that contains the power means and connects to the UV transmissive protective cover.
The system of claim iii further including a safety sensor that prevents the unit from being turned on until an adult hand properly holds it.
The system of claim iv further including a timing circuit that turns the light source off a predetermined time after the sensor turns the light source on.
The system of claim iii wherein the power means includes a battery power supply and an associated ballast circuitry.
