A medicated inhalant dispenser has a plastics material body having a mouthpiece. A pressurized, inhalant source has a canister and a sprout which his moved towards the canister for release of a dose from the canister. The sprout is accommodated in a junction member, which is movable by a cam connected to a pivotal cover for the mouthpiece.

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.

A device for delivering medication to a user may include a main body, an electronics module, and a slider. The main body may include a mouthpiece, a medication reservoir, and a mouthpiece cover, where the mouthpiece cover may be hinged to the main body. The electronics module may include a communication circuit, a pressure sensor, and a switch. The slider may be configured to engage the switch when the mouthpiece cover moves from a closed position to an open position. The switch may be configured to switch the electronics module from an off state or a sleep state to an active state. The electronics module may be configured to never return to the off state after the mouthpiece cover is moved to expose the mouthpiece for the first time by the user.

Methods and apparatuses for the pulmonary delivery of a composition, such as methods and apparatuses for dispersing dry powder medicaments for inhalation by a patient. Elements or aspects of the apparatuses, including receptacle puncturing, mechanisms, deoccluding devices, receptacle impacting devices, and receptacle lock devices or systems.

An inhaler, preferably for insertion into a nostril, in particular a horse's nostril, with a pressure generator, which has a tensioning device for the drive, and with a tensioning mechanism for tensioning the tensioning device, whereby the tensioning mechanism has a lever gear for tensioning the tensioning device.

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. Preferably the dose counting mechanism counter indicates the number of remaining doses in, or the number of dispensed doses from, the inhaler.

Delivery of a dry powder via inhalation can be performed using an inhalation device having an inhalation tube and a hollow extension housing an assembly of components including a plurality of impellers, a puncturing device, and a dry powder container. The delivery of dry powder through the inhalation device is facilitated by the puncturing device puncturing the dry powder container, the impellers directing air flow, and the configuration of the extension and inhalation tube.

A suction actuated valve, for a dry powder inhaler, includes a compressed air lumen; a control chamber for providing suction; and a trigger assembly having a displaceable membrane within the control chamber and configured to seal the control chamber such that suction displaces at least a portion of the displaceable membrane to provide an opening force to the trigger assembly for moving from a closed configuration to an open configuration. A trigger is coupled to the displaceable membrane and configured, in the closed configuration, to occlude the compressed air lumen and configured, in the open configuration, to open the compressed air lumen. The trigger has a first cross-sectional area and the displaceable membrane has a second cross-sectional area greater than the first cross-sectional area such that when suction is provided the displaceable membrane provides a mechanical advantage for moving the trigger from the closed configuration to the open configuration.
