Abstract: An aperture plate is formed from a palladium nickel alloy comprising about 89% palladium and about 11% nickel. There is a generally fine substantially equiaxed grain microstructure throughout the thickness of the aperture plate. The average grain width (W) is in the range of from 0.2 μm to 5.0 μm, in some cases from 0.2 μm to 2.0 μm. Because the grain structure is equiaxed (L/W=1) the grain length (L) is the same as the grain width. The improved aperture plate extends the life of nebulisers, eliminates the risk of premature and unpredictable failure of a nebuliser in service, eliminates the risk of product returns from hospitals and patients, and eliminates the possible risk of fragments of the aperture plate breaking free from the nebulizer.

Abstract: A supplemental oxygen delivery system is described in which Aerosol is delivered into a housing 10, 20, which sits in the circuit from the supplemental oxygen supply and optional humidifier. The supplemental oxygen passes through this chamber 10, 20 in which the aerosol is located, and collects the aerosol transporting it to a patient via a nasal cannula 3 or a face mask 4. An aerosol generator 9 is mounted to the housing 10, 20 and delivers aerosol into an oxygen stream 13 flowing between an inlet 14 and an outlet 15 of the housing 10. The housing 10 also has a removable plug 16 in the base 17 thereof for draining any liquid that accumulates in the housing 10. There is no disruption of oxygen delivery to patients using nasal cannulas who currently have to use a separate face-mask when receiving nebulized medication.

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: An aerosol delivery system has an aerosol generator with a vibrating aperture plate (10) and an actuator (11, 16, 17, 19), a controller (18, 19). The controller in real time monitors (201) the aerosol generator as it is driven for vibration of the aperture plate, and detects (202) a change in an electrical characteristic in response to a transition from a wet state to a dry state of the aperture plate. It automatically modifies (203, 205, 206), during the transition, operation of the aerosol generator in response to the detected change. The modification includes reducing applied power (203). The controller continues (204) to monitor during the transition, including monitoring the aperture plate for presence of residual liquid on the aperture plate first surface. The controller monitors at a number of drive frequencies and maintains data representing trends in a combination of the electrical characteristic signals at the different frequencies, and identifies a start of a transition if a calculated value rises above a threshold. There is one threshold for triggering a check scan for residual volume and a higher threshold to trigger an immediate shut down.

Abstract: An aperture plate is manufactured by plating metal around a mask of resist columns (2) having a desired size, pitch, and profile, which yields a wafer about 60μιη thickness. This is approximately the full desired target aperture plate thickness. The plating is continued so that the metal (3) overlies the top surfaces of the columns until the desired apertures (4) are achieved. This needs only one masking/plating cycle to achieve the desired plate thickness. Also, the plate has passageways (24) formed beneath the apertures (32), formed as an integral part of the method, by mask material removal. These are suitable for entrainment of aerosolized droplets exiting the apertures (32).

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 nebuliser control device (1, 10) has a manually adjustable user interface (2, 12) and a cable (4) extending from the interface to a power source, and a cable (5) extending from the interface (2, 12) to an aerosol generator. The interface is manually adjustable by physical movement of an actuator such a slider (2) or a rotating knob (12) to locally control the operation of the aerosol generator.
