Methods and apparatuses (e.g., systems, devices, etc.) for delivering a nebulized drug agent in the nasal passages concurrent with the lungs.

A handheld misting device has a housing having a dispensing window is arranged and configured to contain a sonic generator, a power source coupled to the sonic generator, a plurality of reservoirs, each containing a liquid, and a plurality of nozzles, each nozzle arranged and configured for removable coupling to the sonic generator. Each nozzle is associated with and in liquid communication with a single reservoir. The sonic generator includes a converter and an elongate horn having a proximal end coupled to the converter and a distal end, and the nozzle is removably coupled to the distal end of the horn. Thus, the device delivers the liquid through a delivery opening formed in the nozzle, and activating the sonic generator energizes the liquid in the nozzle to generate an aerosol plume that is delivered through the dispensing window.

An aerosol generator for generating an aerosol from a fluid, comprising: a vibratable membrane having a first side for being in contact with the fluid and an opposite second side, the membrane having a plurality of through holes penetrating the membrane in an extension direction from the first side to the second side, whereby the fluid passes the through holes from the first side to the second side when the membrane is vibrated for generating the aerosol at the second side, each through hole having along its extension direction a smallest diameter, a larger diameter that is larger than the smallest diameter and defined by that diameter that is closest to triple, preferably twice said smallest diameter, each through hole having a nozzle portion defined by that continuous portion of the through hole in the extension direction comprising the smallest diameter of the through hole and bordered by the larger diameter of the through hole, wherein the ratio of the total length of each through hole in the extension direction to the length of a respective one of said nozzle portions in the extension direction is at least 4, preferably at least 4.5 and most preferred equal to or larger than 5.

An aerosol delivery device having condensing and non-condensing vaporization functionality is provided. The aerosol delivery device may comprise at least one housing, and a first element and second element contained within the at least one housing. The first and second element may be configured to activate and vaporize components of an aerosol precursor composition, and thereby form respectively a condensing vapor and non-condensing vapor. In response to a flow of air through at least a portion of the at least one housing, the condensing vapor or non-condensing vapor may be combinable with the air to form an aerosol.

The present disclosure provides an aerosol precursor consumable, and an aerosol delivery device that comprises a control unit that defines a receiving chamber, and a removable and replaceable aerosol precursor consumable, at least a portion of the consumable configured to be received into the receiving chamber. The aerosol precursor consumable comprises a housing defining an outer wall, an aerosol precursor composition reservoir located in the housing and configured to contain an aerosol precursor composition, an atomizer located in the housing, and at least one aroma diffuser. The atomizer is configured to vaporize the aerosol precursor composition to generate an aerosol for oral delivery to a user, and the at least one aroma diffuser is configured to diffuse an aroma composition for olfactory delivery to the user.

A pacifier comprising a suction part and a housing part, wherein said suction part comprises a nipple and a shield connected to each other, wherein said suction part comprises a passageway through which a fluid can pass from outside a mouth of a user of the pacifier to inside the mouth of the user of the pacifier, and wherein said housing part comprises a housing, wherein said housing is prefilled with a drug which can pass through the passageway into the mouth of the user when the housing part is connected to said suction part and wherein said drug is a drug to be inhaled through the passageway of the suction part.

A nebulizer has an aerosol generator mounted in a housing, and has a vibratable aperture plate mounted to an annular support and to which is attached a vibration generator piezo. A downstream annular resilient seal is mounted between the housing and the washer on a side of the aperture plate opposed to the liquid supply reservoir. An upstream resilient seal is in the form of a gasket and is mounted between the washer and the housing reservoir, and has an opening forming part of a throat over the aperture plate. The gasket has a washer-shaped body extending radially from a downstream-extending rim adjacent the aperture plate. There are two upwardly-directed ridges for engagement with a housing surface, and the gasket is configured so that when under axial compression the opening internal surface is tapered inwardly in a flow direction to form a funnel shape.

Disclosed are an ultrasonic atomization control system and an electronic cigarette. The system includes: a current feedback circuit and/or a voltage feedback circuit, a microcontroller unit, a push-pull circuit, and an oscillator driving circuit; wherein the push-pull circuit is coupled between the microcontroller unit and the oscillator driving circuit, the current feedback circuit and/or the voltage feedback circuit are/is coupled between the oscillator driving circuit and the microcontroller unit; and the oscillator driving circuit is configured to be connected with a load; wherein the microcontroller unit is configured to output a pulse width modulation signal with a predetermined frequency and voltage to the push-pull circuit, judge a current and/or a voltage fluctuation fed back by the current feedback circuit and/or the voltage feedback circuit are/is greater than a threshold, and stop operation of the load if the fluctuation is greater than the threshold.

A vaporizer device may include a vaporizer body configured to couple with at least one vaporizer cartridge including a first reservoir and a second reservoir. The vaporizer device may include a first aerosol generation mechanism configured to generate a first part of an aerosol by at least vaporizing a first aerosol component present in a first vaporizable material in the first reservoir. The vaporizer device may also include a second aerosol generation mechanism configured to generate a second part of the aerosol by vaporizing a first aerosol component present in a second vaporizable material at a second temperature. The first part of the aerosol and the second part of the aerosol may be delivered, via a mouthpiece, to a user of the vaporizer device.

A security tag can prohibit unauthorized usage of a device or product. The device may include an electronic nicotine delivery systems (“ENDS”) device, which may include aerosol delivery devices such as smoking articles that produce aerosol. The security tag can prevent usage until authorized. Attempts at usage without authorization can result in the device being unusable. The authorization may include identity confirmation or age verification.
