A device facilitating the inhalation of powdered medicaments from within a container. The device comprises a body having walls partially defining a chamber, an inlet port into the chamber for the entry of air, and a mouthpiece having a central through opening communicating with the chamber. A support member also partially defines the chamber and is manually movable relative to the body to convey a first portion of the container from (1) a first position spaced from the chamber to (2) a predetermined dispense position within the chamber with an open end of the first capsule portion uppermost so that airflow into the inlet port and through the chamber induced by suction at the mouthpiece will cause the powdered medicament in the first container portion to become entrained in the airflow; and an extractor is mounted for movement relative to the body to remove a second container portion and open the container prior to positioning of the first container portion at the dispense position.

A device facilitating the inhalation of powdered medicaments from within capsules of the type each comprising a first capsule portion adapted to contain the powder and having an open end, and a second capsule portion closing the open end of the first capsule portion, said device comprising a body having walls defining a chamber in the upper portion thereof, a cavity adjacent the chamber, at least a portion of the cavity being located below the chamber, an air opening into said cavity for the entry of air, at least one inlet port up into said chamber from said lower portion of said cavity for the entry of air, and a mouthpiece having a central opening fluidically communicating with said chamber; a generally cylindrical support member having an axis and sockets extending radially and opening through its periphery adapted to receive and support the first capsule portions of a plurality of capsules, respectively, with the second capsule portions projecting from the sockets radially of the support member, said support member being mounted in the cavity of said body for rotation about said axis relative to said body, said inlet port being generally radially adjacent the support member, a portion of the periphery of the cylindrical support member adjacent said inlet port closing a portion thereof, means for moving said sockets one by one from a first position wherein a capsule received in the socket is outside said inlet port to a dispense position wherein the open end of the first capsule portion within the socket is within the confines of said inlet port between said air opening and mouthpiece so that airflow into said air opening and said inlet port and through said chamber induced by suction at the mouthpiece will cause the powdered medicament in the first capsule portion in the socket to become entrained in the airflow; and manually activatable means mounted on said body for removing the second capsule portion from the first capsule portion in the socket at said first position, said manually activatable means for removing comprising an extractor including means for frictionally engaging said second capsule portion, and manually actuatable means for moving the means for frictionally engaging relative to said body between a raised position at which raised position said means for frictionally engaging is spaced from the capsule in the socket of said support member at said first position, and an engage position at which engage position said means for frictionally engaging is in frictional engagement with the second capsule portion of the capsule within the socket of said support member at said first position.
