Patent number: 9463289Abstract: A manually operated metered dose inhaler includes a dose counter chamber including a dose display tape driven by a ratchet wheel which is driven in turn by an actuator pawl actuated by movement of a canister, the tape unwinding from a stock bobbin during use of the inhaler, a rotation regulator being provided for the stock bobbin and including a wavelike engagement surface with concavities which engage against control elements in the form of protrusions on resilient forks of a split pin thereby permitting incremental unwinding of the stock bobbin yet resisting excessive rotation if the inhaler is dropped onto a hard surface.Type: GrantFiled: December 11, 2013Date of Patent: October 11, 2016Assignees: IVAX Pharmaceuticals Ireland, Norton (Waterford) Limited, Teva Pharmaceuticals IrelandInventors: Declan Walsh, Derek Fenlon, Simon Kaar, Jan Geert Hazenberg, Daniel Buck, Paul Clancy, Robert Charles Uschold, Jeffrey A.

Publication number: 20160095991Abstract: A dose counter for counting doses of medicament dispensed by or remaining in a metered-dose inhaler. The dose counter includes: a rotatably mounted gear wheel having a circular arrangement of ratchet teeth; a display coupled to the gear wheel, the display having a visible array of dose counting indicia indexable in response to rotary motion of the gear wheel; and an actuator mechanism having a driver for rotatably driving the gear wheel in response to the dispensation of a medicament dose, the driver being arranged to engage the ratchet teeth of the gear wheel. The actuator mechanism includes a pivotally mounted lever having an input portion. The lever is arranged to amplify a linear stroke at the input portion such that a linear stroke of the driver exceeds the linear input stroke. By amplifying the stroke, the risk of undercounting due to insufficient stroke length may be reduced.Type: ApplicationFiled: December 14, 2015Publication date: April 7, 2016Inventors: Simon G. Kaar, Jeffrey A. Karg, Timothy Norman Johnson, Robert Charles Uschold

Publication number: 20150238714Abstract: A dose counter for a metered dose inhaler includes an incremental counting system for counting doses. The incremental counting system has a main body, an actuator arranged to be driven in response to canister motion and to drive an incremental output member in response to canister motion. The actuator and incremental output member are configured to have predetermined canister fire and count configurations in a canister fire sequence. The canister fire configuration is determined by a position of the actuator relative to a datum at which the canister fires medicament and the count configuration is determined by a position of the actuator relative to the datum at which the incremental count system makes an incremental count. The actuator is arranged to reach a position in the count configuration at or after a position in the canister fire configuration.Type: ApplicationFiled: April 29, 2015Publication date: August 27, 2015Inventors: Declan Walsh, Derek Fenlon, Simon Kaar, Jan Geert Hazenberg, Dan Buck, Paul Clancy, Robert Charles Uschold, Jeffrey A.
