Ultrasonic method and device for wound treatment
First Claim
Patent Images
1. A method for treating a wound comprising the steps of:
- providing a transducer having a distal radiation surface arranged a distance from the surface of the wound for emitting ultrasonic energy;
introducing at least one of a liquid and a powder to the distal radiation surface to produce a spray; and
delivering the emitted ultrasonic energy to the wound through the spray, wherein the ultrasonic energy penetrates the wound tissue to a beneficial depth to provide a bactericidal and a therapeutic effect for decreasing the healing time for the wound.

Abstract
The method and device of the present invention for wound treatment includes a transducer to produce waves, preferably ultrasonic waves. The transducer has tip with the distal end (radiation surface). A liquid is directed to the radiation surface 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 wave trough particles and has an irrigation, mechanical cleansing, liquid energizing and bactericide effect.

9. An apparatus for treating a wound comprising:
-
means for generating ultrasonic energy positioned at a non-contact distance from the surface of the wound; and
means for introducing at least one of a liquid and a powder to at least one propagation path of the generated ultrasonic energy to produce a spray, wherein the generated ultrasonic energy is delivered to the wound through the spray, and wherein the ultrasonic energy penetrates the wound tissue to a beneficial depth to provide a bactericidal and a therapeutic effect for decreasing the healing time for the wound. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A method for treating a wound comprising the steps of:
-
generating ultrasonic energy at a distance from the surface of the wound, such that the generated ultrasonic energy propagates through a gaseous medium;
introducing at least one of a liquid and a powder in at least one propagation path of the generated ultrasonic energy to produce a spray; and
delivering the generated ultrasonic energy to the wound through the spray, wherein the ultrasonic energy penetrates the wound tissue to a beneficial depth to provide a bactericidal and a therapeutic effect for decreasing the healing time for the wound. - View Dependent Claims (17, 18, 19, 20)
