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.

An aerosol inhalation spacer for use with a metered-dose inhaler canister is disclosed. The spacer includes a transparent chamber housing having a body with an input end and an output end and defining an interior space. A mouthpiece is connected to the output end of the chamber housing. An inhaler adapter is connected to the input end of the chamber housing. A valve member is disposed between the mouthpiece and the output end of the chamber housing, the valve member includes a one-way inhalation valve and a one-way exhalation valve. A flow indicator is connected to the inhaler adapter and extends into the interior space of the chamber housing for indicating an inhalation flow rate to the user.

A system may include an external device and an inhaler. The external device may include a processor, a communication circuit, and memory. The inhaler may include a mouthpiece, medicament, a mechanical dose counter, and an electronics module comprising a processor and a communication circuit. The electronics module may record a dosing event when the inhaler is actuated, such as when the mouthpiece cover is opened, and send a signal indicating the dosing event to the external device. The external device may receive a mechanical dose reading of the mechanical dose counter, determine an electronic dose reading based on the signal indicating the dosing event, determine that a discrepancy between the mechanical dose reading and the electronic dose reading exceeds a threshold, and notify the user of the discrepancy, for example, by providing a notification to the user by way of a mobile application residing on the external device.

An inhaler for facilitating inhalation of dry powder includes a body defining an interior space and a mouth piece. At least one annular member is positioned within the interior space and is rotatable with respect to the mouth piece. The at least one annular member includes a plurality of compartments. Each compartment defines a cavity configured to hold dry powder. Each compartment includes at least one flap and an opening configured to release the dry powder when the at least one flap is reconfigured from a closed position to an open position. The at least one flap covers the opening and inhibits the dry powder from being released from the cavity in the closed position.

An electronic module for an inhaler includes a printed circuit board and electronic components configured to detect at least a status and/or at least a working parameter of the inhaler when the electronic module is attached to the inhaler. A battery is permanently joined to the printed circuit board. A first terminal and a second terminal are electrically connectable one to the other through a main switch to close a circuit between the battery and the electronic components. In a rest configuration, the first and second terminals are electrically separated by the main switch. In a work configuration, the first terminal and the second terminal are electrically connected one to the other through the main switch.

A nasal inhaler for the inhalation of inhalable substances comprise: a canister having an interior reservoir containing pressurised inhalable substances including fluid; a metering valve including a metering chamber and a valve stem defining a communication path between the metering chamber and the interior reservoir, the communication path including an opening configured to permit flow between a transfer space inside the valve stem and the interior reservoir, the interior reservoir being arranged for orientation above the metering chamber whereby gas located within the metering chamber is replaced with liquid from the interior reservoir.

Systems and methods of an electronic drug delivery system for use in a treatment program (e.g., a smoking cessation program). The delivery system can include a mobile platform and a hand-held inhalation delivery device having a controller circuit coupled to a power source, sensors, aerosolizer drivers, and a rescue button, and a pod removably coupled to the delivery device. The delivery system generates an aerosol mixture from substances in the pod in accordance with the treatment program, and delivers the aerosol mixture for inhalation by a user. The controller circuit individually and dynamically controls the aerosolizer drivers to generate signals that drive a plurality of thermal, or non-thermal, aerosolizers of the pod to generate individually tailored aerosol mixtures from multiple substances in the aerosolizer pod. The generated aerosol mixtures can have various percentages of the substances, and have different aerosol droplet sizes during different portions of the treatment program.

An inhaler (10) has a main body for accommodating a medicament reservoir (84), a canister fire system for moving a canister (50) to release a dose in response to air flow, a cap housing (12) for enclosing the canister fire system and canister within an interior chamber defined by the main body (14) and a cap housing, wherein a lock system (250) is provided for locking the cap housing on the main body.

A powder inhaler assembly includes a powder inhaler including a metering device having a dosing recess and movable, with respect to a container and to an inhalation channel, between an idle state, in which the dosing recess is in communication with an opening of the container so as to be filled with a dose of the powdered medicament, and a triggered state, in which the dosing recess is in communication with the inhalation channel for enabling inhalation of a dose of the powdered medicament contained in the dosing recess through a mouthpiece. An electronic module is attachable to the powder inhaler and includes a non-contact sensor positioned and configured to sense position(s) of at least part of the metering device to detect at least when the metering device is in the triggered state.

An inhaler for administering powdery dry substances comprises two substance carrying disks (2, 3). Each disk has a cavity filled with a powdery dry substance. The substance carrying disks (2, 3) are rotatably arranged about a common axis of rotation such that the cavities are opposite each other. The inhaler further has an airway (4) having a piercing nozzle (41). The piercing nozzle is disposed between the substance carrying disks (2, 3).
