An aerosol generator with an active liquid container and a nebulization chamber associated therewith, which is connected to an inlet channel for the supply of carrier gas and to an outlet channel for the discharge of carrier gas mixed with aerosol obtained from the active liquid, is intended to enable a particularly good adjustability of the droplet size of the aerosols contained in the discharged carrier gas and thus a use particularly in the context of a transnasal inhalation therapy. For this purpose, the nebulization chamber has a substantially rotationally symmetrical boundary wall, the inlet channel being positioned and oriented in the region of its point of entry into the nebulization chamber in such a way that its longitudinal axis is offset relative to the axis of symmetry of the nebulization chamber in the region of the point of entry and does not intersect the axis of symmetry.

An electrically-powered inhalation device for delivery of an aerosol to the oropharynx of a user comprises respective proximal and distal portions, the proximal portion including an inlet for a liquid, the distal portion including an aerosol outlet defining a mist-exiting location and a piezo assembly including an ultrasonically vibrable mesh membrane, for producing, upon electrical activation, a mist comprising droplets of the liquid, the mesh membrane defining a mist-generating location; and an intermediate portion disposed distally from the proximal portion and proximally from the distal portion, wherein the distal portion is dimensioned to vertically span the user's oral cavity from tongue to hard-palate when the user's lips and/or teeth are transversely engaged with the intermediate portion, so as to place the mist-exiting location in fluid communication with the user's oropharynx.

A portable nebulizer and a vertical-type medicine containing and nebulizing assembly thereof are provided. The vertical-type medicine containing and nebulizing assembly includes a medicine storage module, a nebulizing module and an induction module. The nebulizing module includes a nebulizing device and a first conductive structure. The induction module includes a metal induction element disposed in the medicine storage module and a second conductive structure electrically connected to the metal induction element. The medicine storage casing has an inner surrounding area located in the medicine storage space. The metal induction element has an exposed induction portion exposed on the inner surrounding area for receiving a signal generated by the nebulizing device. Therefore, when a predetermined medicinal liquid contained in the medicine storage space is nebulized through the nebulizing device, the signal generated by the nebulizing device can be transmitted to a microprocessor through the induction module.

A fluid jet ejection device, a method of making a fluid jet ejection head, and a method of improving the plume characteristics of fluid ejected from the fluid jet ejection head. The pharmaceutical drug delivery device includes a cartridge body; and a fluid jet ejection cartridge disposed in the cartridge body. The fluid jet ejection cartridge contains a fluid and an ejection head attached to the fluid jet ejection cartridge. The ejection head contains a plurality of fluid ejectors thereon and a nozzle plate having a plurality of fluid ejection nozzles therein associated with the plurality of fluid ejectors. At least one of the plurality of fluid ejection nozzles has an orthogonal axial flow path relative to a plane defined by the nozzle plate and at least one of the plurality of fluid ejection nozzles has an angled axial flow path relative to a plane define by the nozzle plate.

An aerosol generator with electrical power conducting pins has a vibratable plate with apertures therein and an annular piezo. An annular support member supports the piezo and the vibratable plate. A first electrical power conducting pin engages directly with a first, top, surface of the piezo. A second electrical power conducting pin indirectly conducts electrical power to a second surface of the piezo, by contacting an extension tab. There is a film of cured epoxy adhesive on the tab. The aerosol generator avoids need for soldered joints for electrical contact, and the pins are conveniently mounted parallel to each on the same lateral and top side of the piezo and support member. The pins may have multi-point tips for particularly effective electrical contact.

An inhaler for dispensing a pharmaceutical to infants and respiratory compromised patients is disclosed.

The invention relates to an aerosol delivery device (10) comprising an aerosol generator (3) for generating an aerosol in the aerosol delivery device (10), a sensor (5) configured to detect a use of the aerosol delivery device (10) for aerosol treatment, and a controller (7) configured to deactivate the aerosol generator (3) if no use of the aerosol delivery device (10) for aerosol treatment is detected by the sensor (5). Further, the invention relates to a method for operating an aerosol delivery device (10), comprising the steps of operating an aerosol generator (3) for generating an aerosol in the aerosol delivery device (10), detecting a use of the aerosol delivery device (10) for aerosol treatment by means of a sensor (5), and deactivating the aerosol generator (3) by means of a controller (7) if no use of the aerosol delivery device (10) for aerosol treatment is detected by the sensor (5).

Systems and methods are disclosed for delivering medication to a patient. One such system has an aerosol generator for aerosolizing medication. The generator is located outside the airway of a patient. A chamber is provided for receiving aerosolized medication from the generator. The system has a carrier gas supply tube for delivering carrier gas to the chamber, and an aerosol delivery tube for receiving the aerosolized medication and the carrier gas from the chamber. The aerosol delivery tube delivers the aerosolized medication to the patient. A distal end of the aerosol delivery tube is positioned inside the airway of the patient in order to discharge the aerosolized medication within the patient's airway.

An ultrasonic nebulizer includes: a working tank in which an ultrasonic vibrator is incorporated and in which a working liquid is stored facing the ultrasonic vibrator; a medicine tank that stores a medicinal liquid, at least a bottom portion thereof being dipped in the working liquid; and a main body that includes an oscillation circuit that is to drive the ultrasonic vibrator. The medicine tank is configured to be detachable with respect to the working tank. The working tank is configured to be detachable with respect to the main body.

Systems and methods are provided for aerosolizing and delivering therapeutic substances in an electronic aerosol delivery device with airflow regulation. Calibrated airflow resistance settings enable adjustment and control of flow velocity and or flow volume of air, aerosolized air, and or entrained aerosol particles, through the device, for optimal aerosol delivery among diverse conditions and applications.
