Abstract
The method and device of the present invention for ultrasound wound treatment includes a transducer to produce ultrasonic waves. The ultrasonic transducer has tip with the distal end (radiation surface). A liquid is directed to the radiation surface through central orifice or separate tube wherein an directed atomized particle spray of the liquid is created upon contact of the liquid with the radiation surface. The spray directed to the wound from at least 0.1 inches transmits ultrasound waves trough particles and has an irrigation, mechanical cleansing, liquid energizing and bactericide effect.
