Abstract
A mouth piece exhalation valve for a nebulizer or breathing circuit. The nebulizer has an internal passageway containing an offset causing an inspiration mist flow to bypass the exhaust valve without impingement. The offset includes a deflector which aids in the deflection of the inspiration mist flow away from the exhaust valve. The deflector is also utilized for directing the exhaust flow upon expiration by a patient through the exhaust valve. The exhaust valve design includes a flap or disc having leaves formed by peripheral arcuate cuts to facilitate the opening and the closing of the leafs in accordance with the expiration and inhalation of a patient respectively. The cuts also aid in the re-introduction of any accumulation of fluid on the external surface of the disc and valve back into the inspirational cycle so as to minimize any external buildup of fluid.
