    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 ventilator system (1) comprising a ventilator (2) and a nebulizer (3), and an interface (4) linking said ventilator with said nebulizer in a manner allowing a degree of control of nebulizer operation by the ventilator controller. The interface (4) has a coupler to the ventilator (2), a cable linking said coupler to an interface controller (5), a cable linking said interface controller (5) to a coupler (11) for fitting to the nebulizer (3). The interface controller (5) performs phasic delivery control of the nebulizer in response to commands from the ventilator, and it implements a time-out monitor in which it generates a command to cease nebulization if a start command has not been received from the ventilator controller before expiry of a time-out period.

    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.
