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 nasal droplet delivery device and related methods for delivering precise and repeatable dosages to a subject via the nasal passageways and sinus cavities.

The present application relates to an electronic vaporizer device, an electronic vaporizer device body, and an operation method. The electronic vaporizer device body is used in combination with an electronic vaporizer, the electronic vaporizer device body including: a power supply configured to supply power; an airflow sensor configured to detect an airflow change and output first level information; a main control circuit electrically connected to the airflow sensor and configured to control, according to the first level information, the power supply to supply or interrupt power to the electronic vaporizer.

There is disclosed an aerosol delivery device comprising: a first aerosol generator to generate a first aerosol from a first aerosol precursor and to introduce said first aerosol into a first fluid flow pathway, wherein said first aerosol is sized for pulmonary penetration; a second aerosol generator to generate a second aerosol from a second aerosol precursor and to introduce the second aerosol into a second fluid flow pathway, wherein said second aerosol generator comprises a Venturi aperture to dispense and aerosolise the in second aerosol precursor in the second aerosol generator, wherein the second aerosol precursor is a liquid, and wherein the second aerosol is sized to inhibit pulmonary penetration; wherein the second aerosol is transmissible within at least one of: a mammalian oral cavity and a mammalian nasal cavity, and the second aerosol comprising an active component for activating at least one of: one or more taste receptors in said oral cavity and one or more olfactory receptors in said nasal cavity.

The present disclosure may provide an atomizer and an electronic atomization device. The atomizer may include a shell, a heating assembly, a lid, a base, and a first sealing component. The shell defines a liquid cavity and a smoke outlet. The heating assembly may heat and atomize the liquid into a smoke. The lid and the base may be provided to fix the heating assembly therebetween. The lid defines a liquid inlet communicating with the liquid cavity, and the liquid may flow through to reach the heating assembly. The atomizer may define an air entering hole, such that external air may enter the device through the hole to drive smoke to flow. The first sealing component may be engaged between the lid and the heating assembly, contacting both at the same time and defining air guiding channels to guide the air to flow into the liquid cavity.

A mist inhaler device (200) for generating a mist including a therapeutic for inhalation by a user. The device includes 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).

Methods for the treatment of pulmonary cancers (primary, secondary, metastatic, etc.) using an electronic breath actuated droplet delivery device to deliver a cancer therapeutic directly to the pulmonary system of a subject in need thereof is disclosed. An in-line droplet delivery device and related methods for delivering precise and repeatable dosages to a subject for pulmonary use is disclosed. The in-line droplet delivery device includes a housing, an ejector mechanism, and at least one differential pressure sensor. The in-line droplet delivery device is automatically breath actuated by the user when the differential pressure sensor senses a predetermined pressure change within housing. The in-line droplet delivery device is then actuated to generate a plume of droplets having an average ejected particle diameter within the respirable size range, e.g, less than about 5-6 μm, so as to target the pulmonary system of the user.

A pulmonary drug delivery system is disclosed, including a breath-powered, dry powder inhaler, with or without a cartridge for delivering a dry powder formulation. The inhaler and cartridge can be provided with a drug delivery formulation comprising, for example, a diketopiperazine and an active ingredient, including, small organic molecules, peptides and proteins, including, hormones such as insulin and glucagon-like peptide 1 for the treatment of disease and disorders, for example, diseases and disorders, including endocrine disease such as diabetes and/or obesity.
