Abstract: A dry powder inhaler for delivering medicament from at least one medicament carrier having a plurality of spaced-apart medicament doses. The inhaler includes a housing having regions for accommodating unused and used portions of the medicament carrier, a mouthpiece component extending from the housing and through which a user is able to inhale, a dispensing mechanism arranged in the housing for moving a medicament dose of the medicament carrier to the dispensing position, and a mouthpiece cover being rotatably connected to the housing for sequential movement about a rotation axis from a first position in which the mouthpiece component is completely covered to a second position in which the mouthpiece component is completely covered, and from the second position to a third position in which the mouthpiece component is completely uncovered, the second position being between the first and third positions.

Abstract: Disclosed is a dry powder inhaler for delivering medicament from at least one blister pack, each blister pack having a plurality of spaced-apart blister pockets containing doses of the medicament. The inhaler comprises: a housing for accommodating unused and used portions of the at least one blister pack together with a dispensing mechanism for simultaneously opening at least two blister pockets at a time; and a manifold component through which air can be drawn in use of the inhaler.

Abstract: Disclosed are dry powder inhalers for delivering medicament to a user from a blister pack, the blister pack having a plurality of spaced-apart blister pockets containing doses of the medicament. The inhalers comprise: a housing for accommodating unused and used portions of the blister pack together with a dispensing mechanism for selectively opening the blister pockets; and a manifold component through which air can be drawn in use of the inhaler.

Abstract: Provided is a blister pack for a dry powder inhaler, which dry powder inhaler is configured to deliver a first powder medicament and a second powder medicament different from the first powder medicament. The first and second powder medicaments are contained within blister pockets defined in a strip. A series of blister pockets is defined in the strip, which series extends linearly along the length of the strip. The first and second powder medicaments are contained in blister pockets, e.g. respective blister pockets, of the series. Alternatively or additionally, each of the blister pockets is elongated such as to have a largest dimension parallel with the length of the strip. These measures, either individually or in combination, enable minimizing of the width of the strip in spite of the strip accommodating both the first and second powder medicaments.

Abstract: An inhaler includes a main body having a canister housing, a medicament canister retained in a central outlet port of the canister housing, and a dose counter having an actuation member for operation by movement of the medicament canister. The canister housing has an inner wall, and a first inner wall canister support formation extending inwardly from a main surface of the inner wall. The canister housing has a longitudinal axis X which passes through the center of the central outlet port. The first inner wall canister support formation, the actuation member, and the central outlet port lie in a common plane coincident with the longitudinal axis X such that the first inner wall canister support formation protects against unwanted actuation of the dose counter by reducing rocking of the medicament canister relative to the main body of the inhaler.

Abstract: A dose counter for an inhaler includes a counter display arranged to indicate dosage information, and a drive system arranged to move the counter display incrementally in a first direction from a first station to a second station in response to actuation input. A regulator is provided which is arranged to act upon the counter display at the first station to regulate motion of the counter display at the first station to incremental movements.

Abstract: A method of manufacturing a series of incremental dose counters for inhalers, which includes manufacturing the dose counters with nominal canister fire and dose count positions of a dose counter actuator relative to a dose counter chassis or inhaler main body, and which includes building the dose counters with an average dose count position in the series being, in canister fire process, at or after an average canister fire position in the series.

Abstract: An airflow adaptor for a breath-actuated dry powder inhaler. The airflow adaptor includes a conduit having a proximal end and a distal end, wherein the proximal end allows fluid communication from a deagglomerator outlet port to the distal end of the conduit, and wherein the airflow adaptor further includes provisions for allowing air to flow from a proximal end of the adaptor to a distal end of the adaptor independently of the airflow in the conduit when a breath induced low pressure is applied to the distal end of the airflow adaptor.

Abstract: An incremental dose counter for a metered dose inhaler having a body arranged to retain a canister for movement of the canister relative thereto, the incremental dose counter having a main body, an actuator arranged to be driven and to drive an incremental output member in a count direction in response to canister motion, the actuator being configured to restrict motion of the output member in a direction opposite to the count direction.

Abstract: 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.
