Patent number: 10434269Abstract: A dose counter for counting doses of medicament dispensed by or remaining in a metered-dose inhaler. The dose counter includes a rotatably mounted first gear wheel having ratchet teeth and a display coupled to the first gear wheel, the display having a visible array of dose counting indicia indexable in response to rotary motion of the first gear wheel. The dose counter further includes an actuator mechanism having a first ratchet drive pawl for engaging the ratchet teeth of the first gear wheel in response to the dispensation of a medicament dose, and a second ratchet drive pawl for engaging the ratchet teeth of a gear wheel coupled to the display. In use, a first ratchet tooth of the first gear wheel is rotatably driven by the first pawl and then a second ratchet tooth of the gear wheel coupled to the display is rotatably driven by the second pawl.Type: GrantFiled: October 6, 2015Date of Patent: October 8, 2019Assignee: IVAX INTERNATIONAL B.V.Inventors: Simon G. Kaar, Jeffrey A. Karg, Timothy Norman Johnson, Robert Charles Uschold

Patent number: 10105502Abstract: A dose counter for counting does 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 defining a root circle and 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. The dose counter further includes 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 an actuator shaft mounted for linear movement in response to the dispensing of a dose of medicament. In use, the travel of the driver along the root circle of the gear wheel exceeds the corresponding linear movement of the actuator shaft.Type: GrantFiled: July 28, 2010Date of Patent: October 23, 2018Assignee: IVAX INTERNATIONAL B.V.Inventors: Simon G.

Patent number: 9579474Abstract: 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: GrantFiled: December 14, 2015Date of Patent: February 28, 2017Assignee: IVAX International B.V.Inventors: Simon G. Kaar, Jeffrey A. Karg, Timothy Norman Johnson, Robert Charles Uschold
