    Abstract: A nebulizer (650) has an aerosol generator (651), a reservoir (652), and an aerosol outlet (653). A piezoelectric vibration generator (656) is on a downstream side of a support washer (655), and power to the piezo is provided by a spring contact assembly (657). The assembly (657) has upstanding electrical terminals (680, 681) for contact with electrical supply conductors. There are spring terminals (670) extending around a rim of the spring contact assembly (657) to engage an exposed underside of the washer (655), and a resilient ridge (671) extending in the upstream direction to engage the underside of the piezo (656), which itself is on the downstream side of the washer (655).

    Abstract: A single dose aerosol chamber (110) is used with a dispensing apparatus (100) by users to take a chamber (110), fill the chamber with an aerosolized vaccine (104), and dispose of used chambers (120). A display (103) provides instructions to encourage prompt inhalation by the user from a dispensed and filled chamber. The station allows very fast administration of vaccines to large numbers of people. The aerosol dispenser apparatus detects the chamber is in correct position and delivers a pre-determined dose of aerosol. The chamber has a nebulizer delivery port (114) optimized for delivery of aerosol into the chamber container (111) and to act as a vent during inhalation via the inhalation port (115).

    Abstract: A patient interface (1) is for aerosol treatment, having a base (2) to surround the patient's mouth and nose and engage the skin with a resilient seal, and with a strap (8) to attach to a patient's head. There is a support (3) on and across the base for supporting an aerosol delivery head with prongs (4, 5). An enclosed volume is formed in the interface by attachment of a shell (10), which has an extraction port (11) for attachment of an extraction system (20) to extract gas from this volume. An HFNT system includes a patient interface surrounding the nose and mouth and an aerosol delivery apparatus (4, 6), an extraction apparatus (20), and a controller (100) to control delivery of aerosol and/or gas to the interface and to extract gases from a volume enclosed by the interface. Because of the fully sealed volume within the interface there are a wide range of control scenarios possible, using pressure sensing in the volume, bypass valves (201), dynamically-controllable nebulizer (203).

    Abstract: A nebulizer (1) has an aerosol generator (5) mounted in a housing (3), and has a vibratable aperture plate (41) mounted to an annular support (40) and to which is attached a vibration generator piezo (46). A downstream annular resilient seal (43) is mounted between the housing and the washer (40) on a side of the aperture plate opposed to the liquid supply reservoir (21). An upstream resilient seal (48) is in the form of a gasket and is mounted between the washer (40) and the housing reservoir (21), and has an opening (72) forming part of a throat (8) over the aperture plate (41). The gasket (48) has a washer-shaped body (70) extending radially from a downstream-extending rim (71) adjacent the aperture plate (41). There are two upwardly-directed ridges (74, 75) for engagement with a housing (21) surface, and the gasket is configured so that when under axial compression the opening (72) internal surface is tapered inwardly in a flow direction to form a funnel shape. The gasket may be textured with sufficient surface roughness to deter bubbles from attaching to a surface exposed to the throat.

    Abstract: A nebulizer (1, 102) has a liquid reservoir (3, 112) for supply of liquid to be aerosolized to a first surface of a vibratable aperture plate (41) with apertures having a size in the range of 1µm to 10µm. A drive has a piezoelectric annular element on an aperture plate support to cause the aperture plate to vibrate at a drive frequency of 128kHz to cause droplets to separate from a side of the aperture plate opposed to the reservoir. An outlet conduit (6, 114) is for flow of droplets from the aperture plate. A sensor is arranged with an acoustic transducer in contact with the conduit outer surface to pick up an acoustic signal which is representative of a droplet plume in the conduit, and a processor analyses the signal to provide an output representative of a plume. The monitored acoustic signal frequency band is centred around half of the drive frequency because it takes on average more than one aperture plate cycle to separate a droplet.
