FIELD OF INVENTION [0001] The present invention relates to the treatment of wounds using ultrasound standing waves. In particular, the present invention relates to a method and device of creating ultrasonic standing waves in air and directing them to a wound for delivering aerodynamic forces as ultrasonic radiation pressure and ultrasonic waves as well. Ultrasound radiation pressure increases the blood flow in the wound area, and ultrasound waves kill bacteria, stimulate healthy tissue cells, and treat the wound. BACKGROUND OF THE INVENTION [0002] Ultrasonic waves have been widely used in medical applications, including diagnostics and therapy as well as many industrial applications, e.g., welding, cutting, fiber optics technology, speed meters, etc. Diagnostic use of ultrasound waves includes using ultrasonic waves to detect underlying structures in an object or human tissue. In this method, an ultrasonic transducer is placed in contact with the tissue or object via a coupling medium, and high frequency (1-10 MHz) ultrasonic waves are directed into the tissue. Upon contact with the various underlying structures, the waves are reflected back to a receiver adjacent the transducer. By comparison of the signals of the ultrasonic waves sent with the reflected ultrasonic wave as received, an image of the underlying structure can be produced. This technique is particularly useful for identifying boundaries between components of tissue and can be used to detect irregular masses, tumors, etc. [0003] Three therapeutic medical uses of ultrasound waves include aerosol mist production, contact physiotherapy, and soft tissue ablation. The ultrasound contact physiotherapy procedure may cause a patient significant discomfort and/or pain, and skin may appear raw and damaged. Aerosol mist production makes use of a nebulizer or inhaler to produce an aerosol mist for creating a humid environment and delivering drugs to the lungs. [0004] Ultrasonic nebulizers operate by passing ultrasound waves of sufficient intensity through a liquid, the waves being directed at an air-liquid interface of the liquid from a point underneath or within the liquid. Liquid particles are ejected from the surface of the liquid into the surrounding air following the disintegration of capillary waves produced by the ultrasound. This technique can produce a very fine dense fog or mist. [0005] Aerosol mists produced by ultrasound are preferred because a smaller particle size of the aerosol can be obtained with the ultrasonic waves. One of the major shortcomings of ultrasonic inhalers and nebulizers is that there is no directed aerosol to the target. An air stream is then required to direct the aerosol to the target, but this decreases the efficiency of ultrasound. [0006] Ultrasonic sprayers (Sonic and Materials Inc., Misonix Inc., Sono-Tek Inc., Zevex International, Inc., operate by passing liquid trough central orifice of ultrasound instrument-tip.

OBJECT OF THE INVENTION [0008] It is an object of the invention to provide an improved method and device for treating wounds. [0009] It is also an object of this invention to provide an improved method and device for treating wounds using ultrasound standing waves. [0010] It is a further object of the invention to provide a method and device for increasing blood flow, killing bacteria, and stimulating healthy tissue cell growth. [0011] These and other objects of the invention will become more apparent from the discussion below. SUMMARY OF INVENTION [0012] The present invention is a method and device for using ultrasonic standing waves to treat wounds. Ultrasound standing waves occur as a result of incident and reflected waves from a reflective surface that are traveling in opposite directions. The resultant superposition of the two waves forms standing waves, which create ultrasonic radiation pressure. The standing waves, actually ultrasound radiation pressure, occur when the distance between (a) the distal end of a transducer (as a radiant of ultrasound waves) and (b) the reflected surface (e.g., a wound surface) is: n X .lamda./2, where .lamda. is the wave length and n is a positive integer. The standing waves are more effective in limited space or area as a tube. [0013] According to the invention ultrasound waves are created, directed, and delivered to a wound surface through the air to increase blood flow, kill bacteria, stimulate healthy tissue cells and treat wounds with ultrasound energy. The method of treating wounds involves the use of ultrasound standing waves of a continuous or pulsed ultrasound. [0014] More particularly, the method of the invention comprises producing ultrasound standing waves using a free end surface of an ultrasonic transducer and wound surface. [0015] According to the method of the present invention, the radiation pressure of ultrasonic standing waves increase blood flow in wound area and destroy the surface bacteria to result in a higher disinfecting property of ultrasound. Additionally, the ultrasound also stimulates healthy cell growth to aid in granulization and epithelization of the healing tissue. Other applications of the method can be directed to non-medical uses such as cleansing, drying, sterilizing and coating surfaces of objects and food. [0016] The method of the present invention offers an approach that may re-establish use of some traditional ultrasound and establish a method of treating wound and fighting bacteria without antibiotics when necessary. [0017] The overall concept of the present invention relates in method and apparatus for wound treatment using ultrasonic standing waves through air with no drug. This wound treatment method is possible with combination of different energy sources as an ultrasound, laser, electric current, magnetic field, ultraviolet, microwaves, radio frequency, etc. BRIEF DESCRIPTION OF DRAWINGS [0018] FIG. 1 is a perspective view of an ultrasound wound treatment system with standing waves, according to the present invention; [0019] FIG. 2 is a schematic, lateral cross-sectional view of another transducer useful with the system of FIG. 1.
