    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: A nebulizer (1) comprises a controller (2) linked at its output to a vibrating mesh nebulizer head (3), and at its input to a USB cable 5 and plug (4) for connection to a host system. The link between the plug (4) and the controller (2) is a USB cable (5) with power and data channels. The controller (2) comprises a boost circuit (10), a micro-controller (11), and a drive circuit (12). The latter provides power and control signals via a cable (6) and plug (7) to the head (3). These signals provide power and control for a vibrating membrane receiving a liquid to be aerosolised from a feed container. The controller (2) has a housing (25) with LED status lamps (30), and an ON/OFF button (32). Communication can take place between the controller (2) and the USB power source (4), in compliance with the USB protocol. This allows the controller (2) to be controlled via a host, either locally or remotely. The controller may be a slave device, with the dosing regime determined by the host. This allows comprehensive control and treatment monitoring for a wide variety of situations such as in the home or in hospitals.

    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: An aperture plate 1 comprises an inlet surface 2 for receiving a liquid to be aerosolised, an outlet surface 3 and a plurality of apertures 4 extending therebetween. The apertures 4 are tapered from an inlet opening 10 at the inlet surface 2 to an outlet or exit opening 12. The aperture plate is convex in the direction of the inlet openings 10 and concave in the direction of the exit openings 12. The aerosol exits on the concave side of the aperture plate. The aperture plate of the invention generates an aerosol plume which converges and is particularly suitable for application to the eye.

    Abstract: A digital processor of a nebulizer controller controls and monitors drive current (I) applied to an aperture plate. The drive current is detected as a series of discrete values at each of multiple measuring points, each having a particular drive frequency The processor in real time calculates a slope or rate of change of drive current with frequency and additionally determines a minimum value for drive current leading up to the peak value. The processor uses both the value of the minimum drive current during the scan and also the maximum slope value to achieve reliable prediction of end of dose, when the aperture plate becomes dry.

    Abstract: A nebulizer has an aperture plate, a mounting, an actuator, and an aperture plate drive circuit (2- 4). A controller measures an electrical drive parameter at each of a plurality of measuring points, each measuring point having a drive frequency; and based on the values of the parameter at the measuring points makes a determination of optimum drive frequency and also an end-of-dose prediction. The controller performs a short scan at regular sub-second intervals at which drive current is measured at two measuring points with different drive frequencies. According to drive parameter measurements at these points the controller determines if a full scan sweeping across a larger number of measuring points should be performed. The full scan provides the optimum drive frequency for the device and also an end of dose indication.
