1. An aerosol generating nebulizer including a downwardly extending base connected to a small, cylindrical, portable, hand held gas source, comprising, in combination:
- a pair of circular sleeve members formed integrally with said downwardly extending base;
a first of said pair of sleeve members being an outer sleeve and a second of said pair of sleeve members being a conical inner sleeve having a hollow conduit extending therethrough into said nebulizer;
said small, cylindrical, portable, hand held gas source being connected to said first of said pair of sleeve members and said second of said pair of sleeve members; and
regulator means and biased valve means held within said small, cylindrical, portable, hand held gas source in a neck portion thereof, said valve means being opened when contacted by said conical inner sleeve against the action of a biasing means to accurately control the flow of pressurized gas from said small, cylindrical, portable, hand held gas source, through said neck portion, around said valve means and into said hollow conduit.

Abstract
A hand held, single use, gas mixture discharge unit is provided for existing nebulizers to enable them to be adapted for use as a portable gas flow source for a nebulizer. The nebulizer includes an external downwardly extending base having a gas conduit extending therethrough for connection to a standard oxygen delivery tank, or to a hand held gas mixture discharge unit where it operates a valve in a controlled manner to deliver accurately metered quantities of nebulized liquid type medication to the patient, in substantially any circumstance.

11. The combination of an aerosol generating nebulizer having a downwardly extending base and a small, cylindrical, portable, hand held gas source, comprising;
-
said base having an external sleeve having at least one opening therein and formed from a resilient material and receiving a rim formed on an open end of a neck portion of said small, cylindrical, portable, hand held gas source therein between an inner surface of said external sleeve and an outer surface of an inner conical sleeve; and said inner conical sleeve having a hollow central conduit, an outer end, and a plurality of openings formed therein;
said outer end contacting a valve means held within said neck portion of said small, cylindrical, portable, hand held gas source, and moving said valve means against a biasing means, to control flow of pressurized gas held within said small, cylindrical, portable, hand held gas source through a regulator means, through said neck portion, around said valve means, through said openings in said outer end of said conical inner sleeve, and into said hollow control conduit to said nebulizer. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. An aerosol generating nebulizer connected to a small, cylindrical, portable, hand held gas source, comprising;
-
a base formed on said nebulizer, said base having an external sleeve having at least one opening therein and formed from a resilient material and receiving a rim formed on a neck portion of said small, cylindrical, portable, hand held gas source in an internal screw thread formed between an inner surface of said external sleeve and an outer surface of an inner conical sleeve, formed on said base; said inner conical sleeve having an outer end with a plurality of openings formed therein; a valve means inserted in said neck portion, and normally biased against a valve seat;
biasing means holding said valve means against said valve seat until contacted by said outer end of said conical inner sleeve, whereby said valve means is moved away from said valve seat, a predetermined amount, when said rim of said small, cylindrical, portable, hand held gas source is rotated within said internal screw thread between said external sleeve and said inner conical sleeve; anda plurality of regulator means mounted in said neck portion of said small, cylindrical, portable, hand held gas source to restrict the flow of gas reaching said valve means. - View Dependent Claims (19, 20)
