Abstract
Abstract An inhalation device comprises a body with a dispersion chamber. A rotor is arranged in the chamber and is caused to rotate by passage of air through the chamber. One or more air inlet apertures open into the chamber around the rotor. A mouthpiece communicates with the chamber and air from the chamber can be inhaled through this mouthpiece. A capsule-retaining pocket is arranged to receive a pierced capsule and opens into the chamber. Inhalation of air through the mouthpiece will rotate the rotor, vibrate the capsule, draw medicament from the medicament containing capsule through the chamber and out through the mouthpiece.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
157 words
A medicament inhalation device comprising a body with a dispersion chamber therein, a rotor mounted in one end of said chamber and which is rotatable in the chamber by passage of air there through, at least one air inlet aperture in the body, the said apertures opening into the chamber around the rotor, a mouthpiece on one end of the body through which air from the chamber can be inhaled, and a capsule-retaining pocket in and adjacent the other end of said body and in proximinity to said rotor''s other end to receive a pierced medicament containing capsule and opening into the chamber, a means for providing vibration and passage of medicament from said capsule comprising a capsule contacting means on the other end of said rotor whereby inhalation of air through the mouthpiece will turn said rotor to vibrate and draw medicament from the capsule through the chamber and out through the mouthpiece into the patient.
Claim 2
Dependent Claim
157 words
A medicament inhalation device comprising a body with a dispersion chamber therein, a rotor mounted in one end of said chamber and which is rotatable in the chamber by passage of air there through, at least one air inlet aperture in the body, the said apertures opening into the chamber around the rotor, a mouthpiece on one end of the body through which air from the chamber can be inhaled, and a capsule-retaining pocket in and adjacent the other end of said body and in proximinity to said rotor''s other end to receive a pierced medicament containing capsule and opening into the chamber, a means for providing vibration and passage of medicament from said capsule comprising a capsule contacting means on the other end of said rotor whereby inhalation of air through the mouthpiece will turn said rotor to vibrate and draw medicament from the capsule through the chamber and out through the mouthpiece into the patient.
Claim 3
Dependent Claim
35 words
A device as claimed in claim 1, wherein the body has a capsule-piercing pocket in which a capsule can be removably inserted and pressed against a point in the pocket thereby to pierce the capsule.
Claim 4
Dependent Claim
37 words
A device as claimed in claim 2, wherein the rotor is mounted on a spindle carried by a cross-bar extending across the mouthpiece and said capsule contacting means is a bevel on one and of said rotor.
Claim 5
Dependent Claim
47 words
A device as claimed in claim 3, wherein the capsule retaining pocket is arranged so that one end of a capsule located therein extends into the dispersion chamber and the rotor is so positioned as to brush against the protruding end of the capsule as it rotates.
Claim 6
Dependent Claim
38 words
A device as claimed in claim 1, wherein the rotor includes two blades extending radially and oppositely outwards from a spindle sleeve, one of the said blades having a cut-away portion to provide an unbalance condition for vibration.
