Accuvent aerosol delivery system
First Claim
1. An aerosol delivery system comprising an elongated tubular housing defined by an outer wall and having an interior transverse member dividing said housing into first and second elongated chambers terminating in common first and second ends;
- valve means located at said first common end to permit opposed one-way flows through said first and second chambers; and
nebulizer means having a housing extending through said first and second chambers and having an exit port positioned within one of said first and second chambers whereby an airflow through said one of said first and second chambers draws nebulous fluid from said nebulizer means exit port into said airflow for delivery from said tubular housing.

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.
