The methods described herein provide improvements to the measurement of dose content uniformity of inhaler and nasal devices. The methods involve analyzing and measuring a spray pattern of an emitted spray from an inhaler or nasal device. The spray pattern may be used to determine the dose content uniformity of an inhaler or nasal device.

A first portion (12) of the fluid chamber (4) extends along the length of the collar portion (10) in a height direction (H) of the fluid chamber (4), A second portion (14) of the fluid chamber (4) is arranged adjacent to the first portion (12) in the height direction (H) of the fluid chamber (4). A lateral extension of the first portion (12) in the directions perpendicular to the height direction (H) of the fluid chamber (4) is smaller than a lateral extension of the second portion (14) in the directions perpendicular to the height direction (H) of the fluid chamber (4). Further, the invention relates to a fluid reservoir (2′) for an aerosol generator (50), the fluid reservoir (2′) comprising a fluid chamber (4′) for receiving a fluid (6′), an opening (8′) for guiding the fluid (6′) received in the fluid chamber (4′) outside the fluid chamber (4′), a recess (9) arranged at least partly below the opening (8!) in a height direction (H) of the fluid chamber (4′), and a cover member (30′) which releasably or permanently seals the recess (9). Moreover, the invention relates to an aerosol generator (50) comprising the fluid reservoir (2, 2′).

Dispensing apparatus is provided for delivering and/or dispensing a pre-determined amount of a product in use. The apparatus includes dispensing means having inlet means for allowing product to enter the dispensing means in use, outlet means for allowing product containable within the dispensing means in use to be dispensed therefrom during a dispensing action of the apparatus, and channel means provided between the inlet means and the outlet means for allowing product to move between the inlet means and the outlet means in use. Recess means are defined in the channel means. The dimensions of the recess means define or substantially define the pie-determined amount of product that can be delivered through the outlet means for each dispensing action of the apparatus. The inlet means and/or at least one aperture defined in the dispensing means is arranged and/or is of such dimensions that excess product contained in the channel means that cannot fit into the recess means is able to pass through said inlet means and/or said at least one aperture and out of the channel means in use prior to a dispensing action of product from the outlet means.

An inhalation device for inhaling a vaporized substance that includes metering capabilities to inform a user when a particular amount of substance has been consumed. The inhalation device can include a sensor that senses the vaporized substance and a processor that utilizes data from the sensor to meter the amount consumed. The inhalation device can also define a session, which is a time in which a user can consume a particular amount. During the session, a user can start and stop inhaling and resume inhaling. When the user stops inhaling the inhalation device will halt vapor production and will resume production when the user resumes inhaling.

A dose counting mechanism for an aerosol dispenser is presented where the dose counting mechanism has a first body structure, a second body structure rotatably attached to the first body structure, an annular dose counter provided with a plurality of teeth along its perimeter, the dose counter being arranged coaxially with the first body structure and the second body structure, each of the first body structure and the second body structure being rotatable relative to the dose counter, a rotatable actuator that meshes with the teeth of the dose counter, the actuator being configured to follow the perimeter of the dose counter when the second body structure is rotated relative to the first body structure, and a rotator that rotates concurrently with one of the first body structure and the second body structure and that engages with the actuator when rotation of the first body structure relative to the second body structure is initiated.

The invention relates to the field of inhalation devices for medically active liquids. In particular, the invention relates to a cartridge containing said liquid for such an inhalation devices. A cartridge (1) for the storage of a medically active liquid (L) and for supply of the same to a pumping unit of an inhalation device comprises an outer container (3) enclosing a collapsible inner bag (4), and a cap (5) which is capable of closing the container (3), the cap (5) further providing an openable access opening (6) to the inner bag (4), wherein further, the container (3) of the cartridge (1) has a pressure compensation opening (7), and wherein said pressure compensation opening (7) is located in a region (8) which is covered by the cap (5). In a method for providing a pressure compensation to the collapsible inner bag-containing interior of the outer container (3) of a cartridge (1), initially, before the cartridge (1) is connected to a holder (2), the pressure compensation opening (7) is closed, and subsequently, when the cartridge (1) is connected to the holder (2), by way of mechanically deforming (i) a pressure compensation opening comprising region of the outer container (3) and/or (ii) a compensation opening covering region of the cap (5), an air gap (9) is provided which allows for a pressure equalization of the bag-containing interior with the ambient pressure.

A medication dispenser includes a casing, a notched wheel and a circuitry unit. The casing includes a mouthpiece. The notched wheel has a plurality of notches, and is rotatable to register the notches with the mouthpiece. The circuitry unit includes an annular magnetic member co-rotatably mounted to the notched wheel, and a Hall sensor. The magnetic member has a plurality of alternately arranged first and second magnetic poles. The Hall sensor is in a first detecting state when it detects one of the first magnetic poles, and is in a second detecting state when it detects one of the second magnetic poles.

Devices and methods are described for preparing, managing, and/or administering metered doses of substances for vaporized administration. In some embodiments, dose cartridges comprising at least one botanical substance include a heating element integrated into the cartridge in close contact with the botanical substance. In some embodiments, cartridge-mounted doses are stored in a magazine, optionally in carousel form, before use. Transport of a cartridge from a magazine to an electrically operated vaporizing chamber which activates the heating element is provided by a mechanical pickup means.

A method may include dispensing a dose of an inhalable compound according to a dosing instruction set; and maintaining a hands-free article for dispensing the inhalable compound in an operable dispensing position.

A nebulizer includes an insertable container and a counter device for counting operations of the nebulizer. The nebulizer can be opened for replacing the container. The counter devices blocks opening of the nebulizer until a predetermined number for operations has been reached.
