A breathing treatment delivery device is disclosed for providing atomized medicine or oxygen to a patient. The breathing treatment delivery device can include a supply device configured to dispense atomized medicine or oxygen through a dispensing end of the supply device. A cap can have a device side and a delivery side, the device side including an opening receiving and in fluid communication with the dispensing end of the supply device. A treat holder can be positioned on the delivery side of the cap. At least one aperture can be defined in the delivery side of the cap adjacent the treat holder, a pneumatic passage formed through the cap between the opening in the device side of the cap and the aperture. A patient can enjoy a piece of candy or other treat retained by the treat holder during treatment while breathing in the desired medicine or oxygen.

An aerosol-generating device includes: a housing having a liquid storage cavity for accommodating an aerosol-generating substrate; a metal element arranged outside the liquid storage cavity; a static electricity generating assembly including a positive terminal and a negative terminal, one of the positive terminal and the negative terminal being electrically connected to the metal element so as to cause a part of the aerosol-generating substrate that is close to the metal element in the liquid storage cavity to be charged by electrostatic induction when the static electricity generating assembly is electrified; and a vaporization sheet, that, when electrified, vaporizes the charged aerosol-generating substrate to generate a charged aerosol.

A nasal delivery device for and a method of delivering substance to a nasal airway of a subject, the nasal delivery device comprising: a mouthpiece (519) through which the subject in use exhales to cause closure of the oropharyngeal velum of the subject; a nosepiece (517) for fitting to a nostril of a subject, the nosepiece including a nozzle (549) through which substance is in use delivered to the nasal airway; and a manually-actuatable substance supply unit (520) for delivering substance through the nozzle of the nosepiece.

An aerosol-generating system including a liquid storage portion is provided, the portion including a rigid housing holding a liquid aerosol-forming substrate, the housing having an opening and a fluid permeable heater assembly including a plurality of electrically conductive filaments, wherein the fluid permeable heater assembly is fixed to the housing and extends across the opening of the housing. The provided heater assembly that extends across an opening of a liquid storage portion allows for a robust construction that is relatively simple to manufacture and allows for a large contact area between the heater assembly and liquid aerosol-forming substrate. The heater assembly may be substantially flat, allowing for simple manufacture.

A power supply unit for an aerosol inhaler includes: a case; a power supply that discharges power to a load for generating an aerosol from an aerosol generation source; a discharging terminal that connects the load to the power supply; a charging terminal that connects the power supply to an external power supply and is separated from the discharging terminal; a temperature measuring unit that measures temperature of the power supply; and a control device that controls an effective value of a first charging current to a value smaller than an effective value of a second charging current. The first charging current is supplied to the power supply when a measurement value of the temperature measuring unit is equal to or higher than a first threshold and the second charging current is supplied to the power supply when the measurement value is lower than the first threshold.

A MEMS switch is actuatable by a fluid, and includes a piezoelectric pressure sensor that detects the movement of a fluid generating a negative pressure. The piezoelectric pressure sensor is formed by a chip of semiconductor material having a through cavity and a sensitive membrane, which extends over the through cavity and has a first and a second surface. The piezoelectric pressure sensor is mounted on a face of a board having a through hole so that the through cavity overlies and is in fluid connection with the through hole. The board has a fixing structure, which enables securing in an opening of a partition wall separating a first and a second space from each other. The board is arranged so that the first surface of the sensitive membrane faces the first space, and the second surface of the sensitive membrane faces the second space.

A cartridge for an aerosol-generating system is provided, including a liquid storage portion including a housing containing a liquid aerosol-forming substrate, the housing having an open end; and a heater assembly including: an electrical heating element configured to heat the substrate to form an aerosol, the heating element including a planar filament arrangement having one or more electrically conductive filaments, an electrically insulating substrate having a planar attachment face, the filament arrangement disposed on the planar attachment face, and clamping elements mechanically fixing the filament arrangement to the electrically insulating substrate and applying a pulling force onto the filament arrangement, at least a portion of the heater assembly being fluid-permeable, and the heater assembly being arranged over the open end of the housing.

An information processing device includes a control unit that generates a display image in which a profile and puff detection timing-related information are associated and displayed, the profile being information that relates to an operation performed by an inhalation device that uses a substrate to generate an aerosol, the operation generating the aerosol, and the puff detection timing being the timing at which user inhalation of the aerosol generated by the inhalation device was detected.

An actuator for a metered-dose inhaler is provided. The actuator comprises a body for receiving a canister and a metering valve, and a mouthpiece through which aerosolised canister content can be dispensed.

A mouthpiece for an aerosol provision system. The mouthpiece includes at least one aerosol outlet channel for delivering an aerosol to a user of the mouthpiece. The mouthpiece includes at least one thermal element for controlling the temperature of a portion of the mouthpiece. The portion may include an exterior surface of the mouthpiece, and the thermal element may be configured for heating and cooling the portion of the mouthpiece. In this way, the thermal element may allow for thermal feedback to be provide to the user, such as to their mouth, lips, or tongue whilst they are operating the aerosol provision system.
