Nebuliser
First Claim
1. A nebuliser for atomising a substance to entrain it into a stream of gas, said nebuliser comprising:
- a casing,a nozzle head disposed within said casing and having at least one gas outlet and an open reservoir surrounding said at least one gas outlet and for receiving a substance to be atomised and from which the substance is atomised by a stream of gas passing through said gas outlet,at least two holes opening into the bottom of the reservoir through which the substance to be atomised is drawn by the stream of gas issuing from said at least one gas outlet;
an airflow control device having a bridge bar which is mounted to intercept the gas issuing from said at least one gas outlet, said bridge bar being freely angularly displaceable with respect to the reservoir to deflect the stream of gas issuing from said at least one gas outlet across the open reservoir; and
wherein the nozzle head includes a transverse gallery through which the substance to be atomized is supplied to said at least two holes.

Abstract
An effective nebulizer atomizes fluids or powders carried in a stream of pressurized gas. The nebulizer includes a casing, a nozzle head having at least one gas outlet and a reservoir disposed around the at least one gas outlet for receiving the substance to be atomized, and from which the substance is atomized by the steam of gas. The substance to be atomized is introduced into the nebulizer, at least two holes opening into the reservoir through which the substance to be atomized is drawn by the stream of gas issuing from the at least one gas outlet. Also provided is an airflow control device having a bridge bar which is locatable for interception of the gas issuing from the at least one gas outlet so as to be freely angularly displaceable for deflecting the stream of gas issuing from the at least one gas outlet across the reservoir.
