Patent number: 10994082Abstract: An inhaler for delivery of a medicament by inhalation is disclosed. The inhaler comprises a dispensing mechanism, the dispensing mechanism being configured to dispense a dose of medicament on actuation. The inhaler further comprises a dose counting mechanism comprising a counter and a translating member. The translating member comprises a pawl. The counter comprises a first count wheel, a second count wheel and an intermediate wheel engaged with the second count wheel and in selective engagement with the first count wheel. When the inhaler is fired to dispense a dose of medicament, the dispensing mechanism moves the translating member in a substantially linear direction. The pawl thus rotates the first count wheel, and as the first count wheel rotates, the intermediate wheel is selectively engaged thereby selectively rotating the second count wheel to count the doses of the inhaler.Type: GrantFiled: September 12, 2018Date of Patent: May 4, 2021Assignee: ASTRAZENECA ABInventors: Simon Christopher Berry, Jonas Christiansen, Svend Erik Elgaard, Esben W. Johansen, Claus Schmidt Moller, Jorgen Rasmussen, Henrik Hougaard Vilstrup, William Richard Treneman

Publication number: 20180339119Abstract: An inhaler for delivery of a medicament by inhalation is disclosed. The inhaler comprises a dose counting mechanism comprising a counter. The inhaler further comprises a dispensing mechanism, the dispensing mechanism being configured, on actuation, to dispense a dose of medicament and to adjust the counter. The inhaler further comprises a resetting member configured for movement in a first direction between a first position and a second position to reset the dispensing mechanism, and a prevention mechanism comprising a pair of first and second engaging members. If the movement of the resetting member in the first direction is reversed before it reaches the second position, the first and second engaging members prevent further actuation of the dispensing mechanism until the resetting member is again moved in the first direction. At least one of the first and second engaging members is configured to resiliently flex, under load, into abutment with a substantially rigid component of the inhaler.Type: ApplicationFiled: August 2, 2018Publication date: November 29, 2018Inventors: Svend Erik Elgaard, Jonas Christiansen, Jorgen Rasmussen, William Richard Treneman

Patent number: 6446627Abstract: A dose counter for a metered dose inhaler comprises actuator means (341), drive means (350) for driving a rotary gear (360) in step-wise fashion in response to displacement of said actuator means (341), said rotary gear (360) comprising a wheel having a plurality of ratchet teeth (not shown) around its periphery. Means (364) are provided to prevent reverse rotation of the rotary gear (360). A flexible tape (368) is provided with a visible array of incrementing integers on its surface indicating the number of medicament doses remaining in the inhaler. The tape (368) indexes by a single integer in response to each step of the step-wise rotary motion of the rotary gear (360). A control surface (371) regulates the position of engagement and disengagement between the drive means (350) and the rotary gear (360). In an alternative embodiment (FIG. 6), the control surface (371) is omitted and the means for preventing reverse rotation comprise a stepless restraint (664).Type: GrantFiled: October 22, 1999Date of Patent: September 10, 2002Assignee: Norton Healthcare LimitedInventors: Nicholas John Bowman, Michael John Holroyd, Costaninos Panayi, William Richard Treneman

Patent number: 5673686Abstract: A new inhalation device, which during operation causes an aerosol to be formed inside a chamber such as a capsule (4) which occludes one end (3) of the inhalation tube (1), the capsule having holes at its extremities (7,8) which admit airflow. The airflow causes the powder contained inside the capsule to be surprisingly transported to the capsule extremity contrary to the direction of inhalation, that is towards the air entry holes in the capsule, and then to form an aerosol until all powder has been removed from the capsule or chamber through the tube (1), the during of inhalation being chiefly regulated by the size and proportion of the capsule holes. The tube (1) has air inlets downstream of the capsule to permit a balanced airflow that will transport the finely suspended powder into the lungs, maximizing the fraction of medicament deposited therein.Type: GrantFiled: February 2, 1995Date of Patent: October 7, 1997Assignee: Plurichemie AnstaltInventors: Peter Villax, Rui Peres, William Richard Treneman, Iain Grierson McDerment, Martin Bunce
