Ultrasound wound treatment method and device using standing waves

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.

       9 . A system for treating a wound with ultrasound standing waves, comprising: 
 means for generating ultrasound waves including an ultrasound transducer having a distal radiation surface; and    means for creating at least one ultrasound standing wave by adjusting the distance between the distal radiation surface and a surface of the wound, wherein the at least one ultrasound standing wave creates radiation pressure for providing a bactericidal and a therapeutic effect to the wound for decreasing the healing time for the wound.    
   
   
       10 . The system of  claim 9 , wherein the ultrasound transducer operates at a frequency of from about 10 KHz to 10 3  MHz.  
   
   
       11 . The system of  claim 9 , wherein the distal end of the ultrasound transducer comprises a bushing, wherein the distance between the bushing and the surface of the wound is adjusted for creating the at least one ultrasound standing wave.
