A removable applicator nozzle for use in treating a wound is provided. The removable applicator nozzle includes a nozzle, a valve and a cup. The nozzle includes a proximal portion, a distal opening and a valve interface. The proximal portion of the nozzle is engagable with a portion of a transducer of an ultrasound wound therapy device. The distal opening of the nozzle allows at least a portion of a tip of the transducer to pass therethrough. The valve is engagable with the valve interface of the nozzle and the valve selectively allows fluid to flow therethrough. The cup includes an aperture and a puncturing device. The aperture is engagable with the valve and the puncturing device is able to puncture a bottle that is inserted on the cup. Fluid flows from the bottle, through the aperture and the valve and onto a tip of the transducer. The fluid is then moved to the distal opening of the nozzle by a vacuum effect.

What is claimed is: 1. A method for promoting wound healing comprising the steps of: providing a transducer which emits ultrasonic energy; providing an applicator, comprising: a nozzle including a proximal portion, a distal opening and a valve interface, the proximal portion being engageable with a portion of an ultrasound wound therapy device, the distal opening allowing at last a portion of a transducer tip of the ultrasound wound therapy device to pass therethrough; a valve comprising a valve opening, an upper portion and a lower portion, the upper and lower portion being rotatable with respect to each other, the lower portion being selectively engageable with the valve interface of the nozzle, the upper portion being in fluid communication with a fluid source, and the valve opening selectively allowing fluid to flow therethrough; and a cup including an aperture, the aperture in fluid communication with at least the upper portion of the valve; activating the transducer to emit ultrasonic energy; and turning the cup to selectively allow fluid to flow from the fluid source through the valve opening towards a portion of the transducer; wherein, following activation of the transducer and contact of said portion of the transducer with said fluid a spray is generated, and wherein the emitted ultrasonic energy is delivered to the wound through the spray to decrease the healing time of the wound. 2. The method according to claim 1, wherein when the transducer is activated, the transducer tip vibrates at a rate of about 1 kHz to about 10,000 MHz. 3. The method of claim 1, wherein the fluid is saline. 4. The method of claim 1, wherein the emitted ultrasonic energy is delivered to the wound through the spray from a non-contact distance of at least 0.1 inches between the transducer and the wound. 5. The method of claim 1, wherein the fluid source is a fluid bag. 6. The method of claim 1, wherein the fluid source is a bottle containing saline. 7. The method of claim 1, wherein the ultrasonic energy penetrates the tissue to a beneficial depth to provide bactericidal and/or other therapeutic effects. 8. The method of claim 1, wherein the fluid source is a bottle containing saline, and wherein the bottle is inserted on the cup. 9. The method of claim 1, wherein the step of turning the cup to selectively allow fluid to flow from the fluid source through the valve opening towards a portion of the transducer is performed prior to the step of activating the transducer to emit ultrasonic energy. 10. The method of claim 1, wherein the valve opening has a diameter in the range of about 0.027 inches to about 0.037 inches. 11. The method of claim 1, wherein one or more vent holes are disposed on the nozzle. 12. The method of claim 1, wherein the cup contains a single puncturing device. 13. The method of claim 3, wherein the ultrasonic energy penetrates the tissue to a beneficial depth to provide bactericidal and/or other therapeutic effects. 14. The method of claim 4, wherein the ultrasonic energy penetrates the tissue to a beneficial depth to provide bactericidal and/or other therapeutic effects. 15. The method of claim 9, wherein the valve opening has a diameter in the range of about 0.027 inches to about 0.037 inches. 16. The method of claim 10, wherein the valve opening has a diameter in the range of about 0.031 inches to about 0.033 inches. 17. The method of claim 15, wherein the valve opening has a diameter in the range of about 0.031 inches to about 0.033 inches.
