Abstract
A device for nebulizing a fluid is supplied which has a flow director. The flow director helps to direct any bubbles formed by the nebulizing device away from the nebulizing device. The nebulizing device has a vibrating element with apertures through which the fluid is dispensed. A dispensing chamber is defined between the flow director and the vibrating element. The dispensing chamber has an inlet which is positioned below an outlet so that bubbles naturally migrate up and away from the vibrating element.
