The invention relates to the field of inhalation devices for liquids. In particular, the invention relates to a pumping chamber for such an inhalation device. A pumping unit for an inhalation device for medically active liquids for generation of an aerosol comprises a tubular member (1), a check valve (2), and a counter piece, said counter piece being configured to receive at least a downstream segment of said tubular member (1) and having an interior volume, wherein upstream of said tubular member (1), a reservoir (4) can be fluidically connected with said tubular member (1), and downstream of said counter piece, a nozzle unit (6) can be fluidically connected with said counter piece, and wherein the tubular member (1) comprises an upstream section, a downstream section, and the check valve (2) which is positioned between the upstream section and the downstream section, such that a pumping chamber with a pumping chamber volume is defined which comprises the volume of the downstream section of the tubular member (1) and said interior volume of the counter piece, and wherein tubular member (1) and the counter piece can move relatively to one another, such that the pumping chamber volume is variable. The tubular member (1) comprises at least two mechanically distinct parts (1A, 1B), wherein a first part (1A) provides said upstream section, and a second part (1B) provides said downstream section, and the first part (1A) and the second part (1B) are connected to each other such as to form an interface section (1C) serving as a valve chamber (2B) for the valve (2).

An inhalable composition comprising: one or more cannabinoids or a pharmaceutically acceptable derivative or salt thereof; a propellant comprising HFA-152a; and a glycol and/or glycol ether.

A vaporizer device may include a plurality of cartridges with a plurality of aerosolization assemblies. The plurality of cartridges may include a suspension media and an additive media. The plurality of aerosolization assemblies may include pressurized cartridges connected to a nozzle having a nozzle opening of less than 20 micrometers.

A spacer device for use with a metered dose inhaler (MDI). The spacer device comprises an aerosol chamber for holding the aerosolized medication sprayed from the MDI. According to one particular design, the aerosol chamber has a forward shell, a rear shell, and an extendable barrel in between. The extendable barrel comprises a flexible plastic sheath that is supported by a coiled wire spring. The spacer device further comprises a mounting bracket to hold the MDI. The mounting bracket holds the MDI such that the spray outlet of the MDI is mated with the aerosol chamber. Also, the assembly is configured such that the aerosol chamber is aligned substantially parallel to the actuator boot of the MDI. During use, the aerosol chamber is folded downward away from the MDI. The aerosol chamber is then extended outward to increase its volume.

An electronic inhaler having an embedded system and a method for precise and repeatable delivery of multiple types of medications in different forms to the pulmonary system of a human user. The inhaler can include a housing defining an internal chamber for accommodating at least two cartridges (reservoirs) containing multiple medicines in different states, and a meter reservoir compartments that can automatically provide precise doses of medicine using vacuum pressure sensors. The sensors can be in communication with the internal embedded system/electronics (microcontroller) of the inhaler and the electronics/microcontroller can be in permanent communication with a software application running on the user's smart phone or other electronic device.
