ABSTRACT:
The present invention is directed to an improved nebulizer attachment for use with a powered nebulizer machine for converting liquid medication into aerosol. It includes a reservoir chamber for liquid medication which is adapted to be oriented substantially vertically, has a gas inlet located thereon for connection to a nebulizer machine and has the capability therein to intermix the incoming gas with the liquid medication to create an aerosol. There is also an aerosol outlet for connection to a face attachment for delivery of the aerosol to a user. The present invention also includes a face attachment indirectly connected to the reservoir chamber. Finally, there is a hollow fitting located between the reservoir chamber and the face attachment. This hollow fitting is formed of a plastic tube having a plurality of circumferential, unconnected corrugations of a semi-flexible nature and has only three rest positions for each such corrugation. One rest position is fully compressed, a second rest position is fully open, and a third rest position is tilted with full compression at one point and fully open at an opposite point to create a single non-180.degree. angle.
