A counter mechanism useable with a dry powder inhaler is disclosed. The mechanism features first and second indicator members rotatable about a central axis. The indicator members have counting indicia visible to indicate inhaler doses remaining or dispensed. A coupling transmits rotary motion from the inhaler to the second indicator member when the inhaler is charged with a dose. A slave wheel, rotatable about an axis offset from the central axis, has a drive transfer wheel on one face and a gear on an opposite face. The gear engages the second indicator member, the drive transfer wheel intermittently engages and rotates the first indicator member in response to rotary motion of the second indicator member.

Slave wheel counter mechanism useable with an inhaler

A rotatably actuated counter is disclosed. The counter includes a ratchet driven unit wheel nested within a tens wheel. Each wheel has a radial face displaying counting indicia. The tens wheel is transparent, allowing the indicia on the unit wheel to be viewed adjacent to the indicia on the tens wheel to provide a total count. A slave wheel is positioned between the unit and tens wheels. A gear on one face of the slave wheel engages gear teeth on the tens wheel. A Geneva mechanism on the other face is engaged by a foot on the unit wheel once per rotation. The wheels are rotatably mounted within a housing having a sidewall with a window through which the count indicia may be viewed. The unit wheel rotates in ten increments and then rotates the tens wheel through one increment by engaging and rotating the slave wheel.

Mechanical doses counter for a powder inhaler

Provided herein are dry powder inhalers for the delivery of metered doses of medicament, counters associated with the inhalers for counting and displaying the number of doses administered or remaining within the inhaler, and methods of use thereof.

A telephone handset construction is provided, which has a movable cover which is articulable from a closed position to an open position. The cover has a rigid portion and a flexible portion. When the cover is in the closed position, the flexible portion thereof is furled around front and top portions of the main body of the telephone handset. Upon deployment of the cover, by pulling the rigid portion of the cover in a direction away from the main body of the handset, the flexible portion of the cover is unfurled and moved to a position substantially covering the back of the main body portion of the handset.
