    Abstract: An aerosol generator core (1) has an integral body (2) and membrane (4), and a vibratory drive connected to an electrical voltage supply. In some examples the body provides the vibration drive and comprises a piezoelectric polymer (2) of P(VDF-TrFE) material. In this manner a single manufacturing operation can provide the membrane, the support, and the vibration drive, and operations such as attaching a membrane to an annular support are avoided.

    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 high flow nasal therapy system (1) has a gas supply (2), a nebulizer (12), and a nasal interface (7). There are two branches (11, 10) and a valve (6) linked with the controller, the branches including a first branch (11) for delivery of aerosol and a second branch (10) for delivery of non-aerosolized gas. The controller controls delivery into the branches (11, 10), in which flow is unidirectional in the first and second branches, from the gas supply towards the nasal interface. The first branch (11) includes the nebulizer (12) and a line configured to store a bolus of aerosol during flow through the second branch (10). The valve (6) comprises a Y-junction between the gas inlet on one side and the branches on the other side.

    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 photo-resist (21) is applied in a pattern or vertical columns having the dimensions of holes or pores of the aperture plate to be produced. This mask pattern provides the apertures which define the aerosol particle size, having up to 2500 holes per square mm. There is electro-deposition of metal (22) into the spaces around the columns (21). There is further application of a second photo-resist mask (25) of much larger (wider and taller) columns, encompassing the area of a number of first columns (21). The hole diameter in the second plating layer is chosen according to a desired flow rate.
