Abstract: A sterilizer device adapted to deliver ultraviolet (UV) light to reduce the bacterial burden of skin incisions or wound surfaces in animals and humans. In one embodiment, the sterilizer device includes a microprocessor that is connected to a control unit, a user interface, an audio input/output, a connectivity module, a power source, a timer, a vibrating alert, a sensor for detecting a distance between a treatment area and the device, and a memory. The control unit is connected to a UV light source and an accelerometer. The user interface includes a display screen and control buttons. The audio input/output includes a speaker and a microphone. The connectivity module includes a USB port and/or a wireless connection. The sterilizer device is configured such that when a user activates one or more of the control buttons, the UV light source delivers a safe dose of UV-C that can kill bacteria.
