1. A method for treating an external wound from a non-contact distance d, comprising the steps of:
- positioning an ultrasound transducer such that a distal radiation surface of the ultrasound transducer is positioned at a distance substantially equal to the non-contact distance d from the surface of the external wound; and
creating and maintaining ultrasound standing waves between the surface of the external wound and the distal radiation surface, wherein the ultrasound standing waves are created and maintained in air along the non-contact distance d, wherein the non-contact distance d is determined by the formula;
d=n×
λ
/2,where λ
is the wavelength of an ultrasound standing wave and n is a positive integer, and wherein the ultrasound standing waves create radiation pressure for providing a bactericidal and a therapeutic effect to the external wound for decreasing the healing time for the external wound.

Abstract
The method and device of the present invention for wound treatment with ultrasound standing waves includes a transducer probe to produce ultrasonic waves. The ultrasonic transducer has a tip with a distal radiation surface that radiates ultrasound energy toward the surface of a wound. Ultrasound standing waves occurring as a result of incident and reflected waves from the wound surface create ultrasonic radiation pressure. Ultrasound radiation pressure increases the blood flow in wound area, and ultrasound waves kill bacteria, stimulate healthy tissue cell and treat wounds.

5. A method for treating an external wound from a non-contact distance comprising the steps of:
-
providing a transducer having a distal radiation surface arranged at the non-contact distance from the surface of the external wound for emitting ultrasonic waves; and creating and maintaining ultrasound standing waves in air between the surface of the external wound and the distal radiation surface by adjusting the non-contact distance, wherein the ultrasound standing waves create radiation pressure for providing a bactericidal and a therapeutic effect to the external wound for decreasing the healing time for the external wound. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12)
