ABSTRACT:
A nebulizer manifold has upper and lower, vertically juxtaposed, chambers which have respective check valves enabling the ingress only and the egress only of air from the associated ends of the respective chambers. A nebulizer injects its mist output into the fluid flow in the chamber permitting only the ingress of fresh air past a check valve, to create medicated air for inhaling by a patient. The other chamber receives exhaled air and allows it to flow outwards away from the patient and to suitable biological filters. The nebulizer provides for aspiration of a liquid to a movable plate orifice to allow a fluid jet stream to entrain the liquid and then strike a boss movable with the plate to form a mist. Control of the rate at which medication is being received is effected by moving the orifice plate to alter the amount of aspirated liquid supplied to the jet stream.
