Nebulizer apparatus
First Claim
1. A nebulizer comprising:
- a housing having a chamber for holding an aerosol;
an air outlet communicating with the chamber for permitting the aerosol to be withdrawn from the chamber;
a reservoir for holding a liquid to be aerosolized;
a liquid orifice located in the chamber;
one or more liquid channels defined between the reservoir and the liquid orifice, the one or more liquid channels having a liquid volume;
a pressurized gas outlet located in the chamber adjacent to the liquid orifice and positioned to deliver a flow of pressurized gas into the chamber; and
,a baffle located in the chamber and positioned relative to the pressurized gas outlet and the liquid orifice so as to divert pressurized gas from the pressurized gas outlet and over the liquid orifice, the baffle having a diverter surface area;
wherein the pressurized gas is delivered at a flow rate of 3-5 liters per minute (lpm);
wherein the liquid volume is at least 80 mm3; and
,wherein the diverter surface area is less than 5.0 mm2.

Abstract
A nebulizer includes a housing having a chamber for holding an aerosol, an air outlet communicating with the chamber for permitting the aerosol to be withdrawn from the chamber, and a reservoir for holding a liquid to be aerosolized. The nebulizer also includes a liquid orifice located in the chamber, one or more liquid channels defined between the reservoir and the liquid orifice, the one or more liquid channels having a liquid volume, and a pressurized gas outlet located in the chamber adjacent to the liquid orifice. A baffle is located in the chamber and positioned relative to the pressurized gas outlet and the liquid outlet so as to divert pressurized gas from the pressurized gas outlet and over the liquid orifice. The baffle has a diverter surface area. The liquid volume is at least 80 mm3. The diverter surface area is less than 5.0 mm2.
