Abstract: A single dose aerosol chamber is used with a dispensing apparatus by users to take a chamber, fill the chamber with an aerosolized vaccine, and dispose of used chambers. A display 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 optimized for delivery of aerosol into the chamber container and to act as a vent during inhalation via the inhalation port.

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 1 pm to 10 pm. A drive has a piezoelectric annular element on an aperture plate support to cause the aperture plate to vibrate at a drive frequency of 128 kHz 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.

Abstract: A patient interface (1) is for aerosol treatment, having a base (2) to surround the patients mouth and nose and engage the skin with a resilient seal, and with a strap (8) to attach to a patients 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 dispensing apparatus is for use by users to take a chamber, fill the chamber with an aerosolized vaccine or other medicament, and dispose of used chambers. A display provides instructions to encourage prompt inhalation by the user from a dispensed and filled chamber. The apparatus 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. Once the dose is delivered a visual and/or audible indicator informs the user that the chamber is filled and that they can take the inhalation. The single dose aerosol chamber is optimized for efficient administration of an aerosol.

Abstract: 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.
