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.

A small form factor metered dose inhaler is disclosed. The inhaler includes a casing having a longitudinal axis and a transverse axis. The casing has a mouthpiece opening at one end along the longitudinal axis. The casing is configured to house a medicament canister along the longitudinal axis. The medicament canister contains a plurality of doses of a pulmonary medicament and a metered dose valve configured to release a metered dose of the pulmonary medicament through the mouthpiece opening along the longitudinal axis. A mechanical linkage translates an applied input force to the mechanical linkage into an output force along the longitudinal axis configured to actuate the metered dose valve and release the metered dose of the pulmonary medicament in a direction along the longitudinal axis. The aerosolized medicament exits the casing in a fluid flow which is symmetric in a vertical plane along the longitudinal axis.

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.

An inhaler housing (14) for an inhaler (10) for inhaling inhalable substances, the inhaler having: a body (14) and a dose counter (24) with a return spring (28), wherein a distinct guide surface (162) is provided for guiding the end of the return spring into a recess (152), the distinct guide surface being wider than an entrance mouth (160) of the recess, a dose counter chamber (22) being provided which is separated from a tubular interior space (182) of the inhaler by a barrier (180), the barrier including a stepped upper wall area (184) including at least three steps (186, 188, 190, 192) at different levels, the inhaler having a valve stem block (62) having an inner bore and a valve stem block having a seal (224) in the inner bore with a second diameter which is smaller than a first diameter of the inner bore, the inhaler having a canister (150) being adapted to move during operation between 1 and 4 mm, a drive being arranged to apply a firing force of between 15 N and 60 N of force to the canister at a position of the canister relative to a valve stem (54) at which the canister fires.

A capsule for an aerosol-generating device may include a housing, a filter, and an aerosol-forming substrate. The housing may have a gas-permeable end and an impermeable end. The filter may be disposed within the housing so as to be adjacent to the impermeable end. The aerosol-forming substrate may be disposed within the housing so as to be between the filter and the gas-permeable end. The housing may be configured to facilitate a heating of the aerosol-forming substrate via one of conduction, convection, or both conduction and convection so as to generate an aerosol.

A venturi inhalation device is provided. The device has a tube defining an internal volume with a fine bore needle disposed at one end. The fine bore needle is in fluid communication with the internal volume of the tube such that medication stored therein can pass into the needle. The tube has a second end which can be sealed to contain the medication until the device is used. A hollow housing is sized and shaped to receive the tube in close tolerance, whereupon the tube being so received, an air-tight seal is formed. The housing also includes a venturi restriction, and when the tube is received by the first end of the housing, a distal end of the fine bore needle is placed within the venturi restriction. A mouthpiece is disposed on a second end of the housing enabling a user to inhale the medication in the tube.

The method and system according to preferred embodiments of the present invention allows an effective delivery of aerosolized medicament (e.g., a surfactant) to the patient's lungs. According to a preferred embodiment, the method of the present invention provides an efficient delivery of the aerosol medicament (possibly breath synchronized). A glass vial in which medicaments are usually stored and shipped is used directly as a component of the system. Its function in the system is that of an intermittently pressurized chamber that can inject the surfactant into the catheter of the atomizer device. According to a preferred embodiment the delivery can be done in phase with the beginning of each inspiration. The main elements of the system are: a source of compressed gas, the already mentioned medicament vial, a catheter, and optionally means to detect the breathing pattern and a control unit.

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.

The present invention relates to devices, systems, and methods wherein certain embodiments of the invention include, but are not limited to milling and dispensing, forming and administering, prescribed dosages of one or more combustible medicaments including medical cannabis, dried flower containing tetrahydrocannabinol (THC), dried flower containing cannabidiol (CBD), and hemp dried flower for inhalation and treatment of various conditions and indications.
