Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
318 words
An inhalation device comprising, in combination, a medicament chamber capable of storing finely-divided medicament therein, an air inhalation chamber, and a substantially cylindrical medicament delivery member communicating between said medicament chamber and said air inhalation chamber, said medicament chamber having a downwardly directed funnel-shaped bottom wall having a bottom opening therein and having an upwardly extending sidewall from said bottom wall with a closed top to define said chamber, said air inhalation chamber having a longitudinally extending outer wall having a top opening therein and two opposing ends, a side air inlet means 5 formed in a closed end wall at the first of said ends and a mouthpiece air outlet means having a transverse screen associated therewith located at the second of said ends opposite to said air inlet means, said side air inlet means comprising a passage extending through said end wall at an oblique angle with respect to the plane of orientation of said first opposed end, the longitudinal axis of said passage being positioned so as to intersect the outer wall of said air inhalation chamber at a point directly beneath and opposite to said top opening therein, said medicament delivery member having a cavity of predetermined volume therein with an opening therefor and being vertically rotatable between a first'position wherein said cavity opening is vertically aligned with said bottom opening of said medicament chamber so as to fill said cavity with a predetermined dose of medicament from said medicament chamber and a second position wherein said cavity opening is vertically aligned with said top opening of said air inhalation chamber so as to enable the predetermined dose of medicament to pass into said inhalation chamber, whereby inhalation of air from said air inlet means into said air inhalation chamber and from said mouthpiece air outlet means effects movement of said predetermined dose of medicament through said air inhalation chamber and from said mouthpiece.

An inhalation device according to Claim 1 wherein the air inhalation chamber and the mouthpiece air outlet means both have an elliptical transverse cross-section.
Claim 5
Dependent Claim
22 words
An inhalation means according to Claim 1 having external means for indicating the position of the cavity in the medicament delivery member.
