A fragrance suitable for a user can be provided. A mobile terminal includes: an acquisition unit that acquires a psychosomatic state from a physiological index of a user; an input unit that inputs future information of the user; a determination unit that determines a recipe including one or more types and a mixing ratio of one or more perfumes based on the psychosomatic state and the future information; and a communication unit that transmits the recipe to a fragrance generation device.

An aperture plate is manufactured by plating metal around a mask of resist columns having a desired size, pitch, and profile, which yields a wafer about 60 μm thickness. This is approximately the full desired target aperture plate thickness. The plating is continued so that the metal overlies the top surfaces of the columns until the desired apertures are achieved. This needs only one masking/plating cycle to achieve the desired plate thickness. Also, the plate has passageways formed beneath the apertures, formed as an integral part of the method, by mask material removal. These are suitable for entrainment of aerosolized droplets exiting the apertures.

Systems and methods are provided for delivering one or more drugs. In some embodiments, a drug delivery system includes a housing having a distal end with an inlet through which an inspiratory flow of air passes into the housing, a proximal end having a patient interface attached thereto, the patient interface being configured to interface with a user, and an inspiratory flow pathway extending from the distal end to the proximal end of the housing. A nitric oxide (NO) source is positioned within the housing and is configured to deliver NO-containing gas to the patient interface. A secondary drug source is positioned within the housing and is configured to deliver a secondary drug to the patient interface. A controller is configured to control an amount of NO-containing gas and an amount of the secondary drug delivered using a control scheme.

Antiseptic agent delivery systems and methods are provided, one such system comprising: a reservoir configured to store an antiseptic solution, wherein the antiseptic solution comprises an aqueous solution of hypochlorous acid; an ultrasound generator coupled to the reservoir, wherein the ultrasound generator vaporizes the antiseptic solution into an antiseptic vapor; a nozzle to direct the antiseptic vapor to an affected area; and a housing coupled to the reservoir and the nozzle, wherein the housing comprises a panel to control the ultrasound generator.

An aerosol-generator for an aerosol-generating device is provided, including: a surface acoustic wave atomiser including: a substrate including an active surface defining an atomisation region, first and second transducers positioned on the active surface; first and second supply elements to respectively supply first and second liquid aerosol-forming substrates to the atomisation region; a controller to provide first and second drive signals respectively to the first and the second transducers to generate surface acoustic waves on the active surface, provide the first drive signal only when the first substrate is supplied to the atomisation region by the first supply element, and provide the second drive signal only when the second substrate is supplied to the atomisation region by the second supply element. An aerosol-generating device including the aerosol-generator is also provided.

A power supply unit of an aerosol generating device includes: an accommodating portion with a bottom and cylindrical shape, which is configured to accommodate a columnar cartridge that stores an aerosol source in a state in which the cartridge is rotatable 360 degrees in a circumferential direction of the cartridge. A rotation suppressing portion configured to generate a frictional force between the cartridge and the rotation preventing portion so as to suppress rotation of the cartridge in the circumferential direction is provided on a bottom portion of the accommodating portion.

Multistage vaporizers, such as for use in medical treatment systems, as well as related methods are described. In one example, a multistage vaporizer includes a first reservoir configured to hold a liquid and one or more pumping transducers positioned in the first reservoir. The multistage vaporizer also includes a second reservoir and one or more vaporizing transducers positioned in the second reservoir. The one or more pumping transducers positioned in the first reservoir are configured to generate and move droplets of a liquid in the first reservoir to the second reservoir, and the one or more vaporizing transducers positioned in the second reservoir are configured to create a vapor of the liquid in the second reservoir.

An electronic device for producing an aerosol for inhalation has a mouthpiece and an elongate housing. The mouthpiece attaches to an upper end of the housing. The housing contains a liquid container and a mesh assembly with mesh material that vibrates when actuated for aerosolizing liquid from the container. The mouthpiece covers the mesh assembly at the upper end of the housing, and the aerosol produced by the mesh assembly may be inhaled through the mouthpiece by a person. The housing contains circuitry and a power supply, preferably are located in a lower half of the housing, for actuating vibration of the mesh material. Electrical pathways connect the mesh assembly with the circuitry and power supply. The power supply may comprise one or more batteries located at the lower end of the housing. The aerosol is produced without smoldering of the liquid and without using a compressed gas.

An ultrasonic electronic rhinitis therapeutic apparatus with far-infrared atomized coconut essential oil is disclosed. The apparatus includes a nasal plug part and a nasal alar part. The nasal plug part includes an insertion column disposed in a nostril. The insertion column is internally provided with a coconut powder, and a far-infrared generating tube is arranged in the coconut powder. An ultrasonic generator is arranged in the nasal alar part, and the nasal alar part is fitted on the lateral side of the nasal alar. In the disclosure, the oil and acid substance in the coconut powder are atomized by far-infrared light and are atomized under the aid of pulse ultrasonic wave in the nasal cavity to be inhaled into the internal tissues of the nasal cavity, sinus and the like.

A dispersion device includes a first dispersion generating system, a second dispersion generating system and an outlet end element including a first outlet corresponding to the first dispersion generating system and a second outlet corresponding to the second dispersion generating system.
