A mist inhaler device (200) for generating a mist comprising a therapeutic for inhalation by a user. The device comprises a mist generator device (201) and a driver device (202). The driver device (202) is configured to drive the mist generator device (201) at an optimum frequency to maximise the efficiency of mist generation by the mist generator device (201).

Liquid drug cartridges and an associated inhaler are used to deliver one more separate doses of an aerosolized liquid drug. A cartridge includes a container for storing the liquid drug, an end cap having an ejection opening, a filter element, and a piston that is repositionable relative to the container to selectively eject a volume of liquid drug from the ejection opening. The filter element filters the liquid drug prior to ejection from the ejection opening. The liquid drug cartridge can be coupled with an inhaler that includes an aerosol generator. The aerosol generator includes a vibratable membrane onto which the liquid drug is ejected. The liquid drug is aerosolized by the vibration of the membrane for inhalation by a user.

The present disclosure provides a method and device for delivering a pharmaceutical to the airway of a human or animal patient. In one aspect, the device includes a dose drum formed into a cylinder and including a plurality of dose compartments for containing individual doses. In another aspect, the device may include a reservoir containing a pharmaceutical material in bulk form and a metering recess for metering the pharmaceutical material to form a pharmaceutical dose. Another aspect provides an inhaler with a combined reservoir and dosing chamber configured to contain multiple doses of a pharmaceutical material.

A medicament delivery device may include a blister disposed about a blister axis. A dosing chamber may be configured to receive medicament from the blister and the dosing chamber may be disposed about a chamber axis. A transducer may confront the dosing chamber. The transducer may be configured to aerosolize the medicament when the transducer is activated. The chamber axis may be transverse to the blister axis when the blister is in a dosing position.

Systems for dense phase transport of frozen and other particles to the respiratory system include a particle source, a delivery chamber for metering boluses of the particles from the source, and a transfer tube for fluidized transport of the particles to a patient interface. A controller may be provided to adjust the rate and amount of the bolus deliver to a patient to control core body temperature and for other purposes.

An ultrasonic electronic cigarette atomizer and an electronic cigarette, wherein the ultrasonic electronic cigarette atomizer comprises a shell, a tobacco tar storage bottle, an ultrasonic atomization piece and a flaky tobacco tar storage body fit to one side face of the ultrasonic atomization piece are provided in the shell, and a tobacco tar guide body is fixed to an outer wall of at least one side of the tobacco tar storage bottle; one side face of the tobacco tar guide body is communicated with the inner cavity of the tobacco tar storage bottle, and the other side face of the tobacco tar guide body is contacted with the side face of the tobacco tar storage body which is away from the ultrasonic atomization piece; and the ultrasonic atomization piece and the tobacco tar storage body are provided to be parallel to the length direction of an electronic cigarette.

An apparatus includes a chamber and an intake device configured to control a flow of fluid into the chamber. The fluid comprises particles; a resonance device is configured to resonate the chamber to provide an acoustic standing wave within the chambers. The frequency of the standing wave is selected to cause particles above a specific size to collect at a node of the standing wave.
