The present invention provides an inhaler comprising a housing which contains a blister strip having a plurality of blisters which contain powdered medicament for inhalation; a mouthpiece through which the medicament is inhaled by a user; an indexing wheel for indexing the blister strip; an opening mechanism for opening the blisters; an actuator which is movable between a first position and a second position in order to operate the indexing wheel and the opening mechanism; and a coupling mechanism for coupling the actuator to the indexing wheel so that the indexing wheel rotates together with the actuator during part of the motion of the actuator; characterized in that the coupling mechanism comprises a shuttle that rotates on the same axis as, and translates axially relative to, the indexing wheel.

An inhalation monitoring system includes an inhaler having a medicament delivery apparatus configured to deliver medicament to a user during an inhalation of the user; inhalation monitoring apparatus, configured to, during the inhalation, gather data for determining a measure of the user's lung function and/or lung health; and a processor configured to receive the data from the inhalation monitoring apparatus and, using the data, determine a measure of the user's lung function and/or lung health.

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.

The invention discloses an accessory for an inhalation device having a canister and a housing including a mouthpiece from which the medicament is dispensed. The accessory includes a jacket, which attaches to the housing; a cap for the mouthpiece and a plurality of elastomeric straps which secure the jacket to the cap. An inhalation device is also provided with the accessory attached.

Provided is a system comprising an inhaler. The inhaler comprises a use determination system. The use determination system is configured to determine a parameter relating to airflow during a use of the inhaler by a subject. The use determination system also assigns a time to the use. The system also comprises a user interface, and a processing module. The processing module is configured to determine inhalation information from the parameter, and control the user interface to issue a notification that the inhalation information is available. The notification is issued at a notification time. The processing module is configured to implement a deliberate time delay such that the notification time is delayed relative to the time assigned to the use.

Provided is a system comprising a plurality of inhalers that each include a processor configured to determine a value of a usage parameter relating to use of the respective first inhaler, encrypt data based on the value, and transmit the encrypted data. At least two of the inhalers include different medicament, such as a rescue medicament and a maintenance medicament. The system includes an external device that includes a processor configured to distinguish between the encrypted data of each respective inhaler, determine respective usage information relating to each of the distinct types of medicament based on the respective encrypted data, and control a user interface (e.g., of the external device) to communicate the usage information related to each inhaler and/or each respective type of medicament.

An inhaler having an air inlet, a medicament source, and an outlet for delivering an air and medicament admixture to a user, the inhaler including a primary power supply for powering the controller and a sensor for detecting a recent shake event, wherein, the sensor is independent of the primary power source and, in use, the sensor provides the controller with a signal indicative of any recent shake event upon the powering up of the controller prior to use of the inhaler.

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. This, in turn, may enable the depth/thickness of the dry powder inhaler to be minimized, and/or additional space to be provided inside the dry powder inhaler for accommodating, for example, use detection and wireless connectivity electronics for sending use detection data to an external device, such as a smartphone.

The present invention provides a dry powder inhaler comprising: a reservoir containing a dry powder formulation and an arrangement for delivering a metered dose of the medicament from the reservoir; a cyclone deagglomerator for breaking up agglomerates of the dry powder medicament; and a delivery passageway for directing an inhalation-induced air flow through a mouthpiece, the delivery passageway extending to the metered dose of medicament, wherein the formulation comprises an inhalable β.sub.2-agonist having a particle size distribution of d1O<1 μπ.Math.=1-3 μπ.Math., d90=3.5-6 μm and NLT 99% 10 μm and a lactose carrier.

A device for dispensing individual doses of powder from respective pockets of a disc-shaped carrier by outwardly rupturing a lidding foil by means of pressure on an opposite side surface, the device providing individual respective deaggregation flow paths for each pocket, split airstreams allowing improved entrainment of powder, a cam mechanism for outwardly rupturing the pockets, an indexing mechanism linked to the cam mechanism and a dose counter.
