Oral inhalator powder dispenser

Claim 2

An oral inhalator powder dispenser comprising: (A) a cylindrical housing containing an upper and a lower portion; a baffle within said housing separating the upper and the lower portion; a converging funnel-shaped mouthpiece extending laterally from said upper portion; and communicating therewith; aperture means for supporting an open-ended powder medicament capsule on the top of said housing; an opening adjacent said aperture means on the top of said housing; an impeller disposed in said upper portion; and a shaft connected to said impeller at one end and protruding through said baffle; and (B) rotary means contained in the lower portion of said housing and connected to said shaft at the other end thereof.

Claim 3

A dispenser described in claim 1 wherein said aperture means is an angular opening on the top of said housing.

Claim 4

A dispenser described in claim 2 wherein said opening is in a concentric arrangement around said aperture means.

Claim 5

A dispenser described in claim 1 wherein said rotary means comprises: an electric motor connected to said shaft contained in the lower portion of said housing; at least one battery contained in the lower portion; a switch on the side of the lower portion; and an electric connecting means such that when said switch is activated, said motor will energize said shaft.

Claim 6

A dispenser described in claim 1 wherein said impeller is a backward bladed impeller.

Claim 7

A dispenser described in claim 1 wherein said impeller is a radial bladed impeller.

Claim 8

An oral inhalator powder dispenser comprising: (A) a cylindrical housing containing an upper and a lower portion; an impeller disposed in the top section of said upper portion; a power turbine disposed in the bottom of said upper portion; a first baffle within said housing separating said impeller in the top and extending laterally from said power turbine in the bottom of the upper portion and a second baffle separating the upper and the lower portion; a converging funnel-shaped mouthpiece on the side of the upper portion; and communicating therewith; aperture means for supporting an open-ended powder medicament capsule on the top of said housing; an opening adjacent said aperture means on the top of said housing; a shaft connected to said impeller at one end and protruding through said first baffle and connected to said power turbine at the other end thereof; and a (B) Compressed gas power source contained in the lower portion of said housing wherein said power source comprises: a compressed gas container having an outlet portion and a valve in said outlet portion; said bottom of said upper portion defining a chamber within which said turbine is rotably disposed; said chamber having an an inlet port and an exhaust port opposingly disposed in said housing adjacent said power turbine, said inlet port extending through said second baffle and connected to said outlet portion of said container, and said outlet port communicating to atmosphere; a pin secured in said gas inlet port adjacent said outlet portion of said container; and means in said lower portion for activating said gas container valve by said pin whereby, the compressed gas will rotate said power turbine and energize said shaft.

Claim 9

An oral inhalator powder dispenser comprising: (A) a cylindrical housing containing an upper and a lower portion; an impeller disposed in the top section of said upper portion; a power turbine disposed in the bottom of said upper portion; a first baffle within said housing separating said impeller in the top and extending laterally from said power turbine in the bottom of the upper portion and a second baffle separating the upper and the lower portion; a converging funnel-shaped mouthpiece on the side of the upper portion; and communicating therewith; aperture means for supporting an open-ended powder medicament capsule on the top of said housing; an opening adjacent said aperture means on the top of said housing; a shaft connected to said impeller at one end and protruding through said first baffle and connected to said power turbine at the other end thereof; and a (B) Compressed gas power source contained in the lower portion of said housing wherein said power source comprises: a compressed gas container having an outlet portion and a valve in said outlet portion; said bottom of said upper portion defining a chamber within which said turbine is rotably disposed; said chamber having an an inlet port and an exhaust port opposingly disposed in said housing adjacent said power turbine, said inlet port extending through said second baffle and connected to said outlet portion of said container, and said outlet port communicating to atmosphere; a pin secured in said gas inlet port adjacent said outlet portion of said container; and means in said lower portion for activating said gas container valve by said pin whereby, the compressed gas will rotate said power turbine and energize said shaft.
