Self-puncturing liquid drug cartridges and an associated inhaler are used to deliver one or more separate doses of an aerosolized liquid drug. A cartridge includes a needle assembly coupled to a drug container. The needle assembly includes a hollow needle and is reconfigurable from a first configuration to a second configuration upon insertion of the cartridge into the inhaler. In the first configuration, the hollow needle does not extend into the container. In the second configuration, the hollow needle extends into the container. The inhaler includes an aerosol generator that includes a vibratable membrane that aerosolizes liquid drug ejected from the cartridge for inhalation by a patient.

An ultrasonic nebulizer is provided that has a liquid chamber to receive a liquid. A piezoceramic transducer is attached to one end of the liquid chamber. The piezoceramic has an orifice to allow the liquid inside the chamber to exit. A plunger movably and sealbly is inserted into the liquid chamber from its other end, which is moved by a moving mechanism to push the liquid out of the liquid chamber. The plunger forms a small liquid droplet on the surface of the piezoceramic. Oscillation of the piezoceramic at megahertz frequencies results in atomization and formation of small droplets from the surface of the sessile droplet. The present nebulizer is a total consumption nebulizer, since all its droplets are substantially within 2 to 5 microns, which is the size range to penetrate into the lunges of a user.

An aerosol delivery device includes at least one housing, a heating element, a sensor, and a microprocessor coupled to the heating element and the sensor. The at least one housing encloses a reservoir configured to retain an aerosol precursor composition. The sensor is configured to produce measurements of differential pressure between an ambient atmospheric pressure and a pressure caused by airflow through at least a portion of the aerosol delivery device. The sensor is also configured to convert the measurements of differential pressure to corresponding electrical signals. The microprocessor is configured to receive the corresponding electrical signals and operate in an active mode only in an instance in which the differential pressure is at least a threshold differential pressure. The microprocessor in the active mode is configured to control the heating element to activate and vaporize components of the aerosol precursor composition.

The present invention provides a single-use, pre-packaged, sealed container (1) for use with a nebulizer device having an aerosol generator comprising a membrane, the container containing a cleaning liquid (3) and being configured to fit onto the nebulizer device, so that the container is held in place on the nebulizer device and the membrane is immersed in the liquid. The invention also provides a strip comprising a plurality of containers (10), wherein each container is detachable from the rest of the strip; a pack comprising a multi-day supply of a drug and containers; and a method for cleaning the membrane of a nebulizer device using the container.

A wicking member and methods of use of the same are disclosed herein. The wicking member can be a component of a medication inhaler. The medication inhaler can include a reservoir bowl defining a reservoir wherein a volume of liquid can be received. The reservoir bowl can include a top, a bottom, and a wall extending from the top to the bottom of the reservoir bowl. The medication inhaler can further include a wicking member proximate to the wall. The wicking member can extend along the wall at least partially from the top of the reservoir bowl to the bottom of the reservoir bowl. The wicking member can wick liquid to the bottom of the reservoir bowl.
