Abstract: A system, method, and apparatus for rapid transdermal disinfection includes a processor or equivalent that generates a series of pulses having pulse widths limited to less than two microseconds. The pulses are amplified to a direct-current voltage of between 150 volts and 500 volts and connected to a positive electrode for attaching to an animal. A negative electrode for attaching to the animal is electrically connected to a current limiter for limiting electrical current flow between the positive electrode and the negative electrode to between 0.2 amps and 2 amps.

Abstract: A method of treating an infant's bottom while changing diapers and a method employing such device involves a handheld blower and bactericide generator. The blower forces warmed air against the infant's bottom and ultraviolet lights supported in the blower irradiate the infant's body and the heated air to reduce bacteria. The ultraviolet lights are pulsed to enhance the antibacterial action.
