Germicidal toothbrush amp; germicidal toothbrush holder sterilization by directing ultra violet germicidal light by total internal reflection through an optical fiber that conducts light

摘要

A germicidal toothbrush and cleaner that uses a germicidal light source to disinfect the individual bristles on the toothbrush. The toothbrush includes bristles made of optical fibers capable of transmitting ultraviolet light. There is also a special method of attachment of the toothbrush inside the cleaner that secures the toothbrushes in a set position in the holder. The germicidal light source may be a germicidal fluorescent ultraviolet lamp. The light rays from the germicidal light source are directed at the opposite ends of the bristle at the critical angle, or slightly greater than the critical angle, in order to attain total internal reflection of the light down the bristles of the toothbrushes.
