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.
