    摘要： 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.

    摘要： A nebulizer comprises a controller linked at its output to a nebulizer head, and at its input to a USB cable and USB plug for connection to a host system. The link between the USB plug and the controller is a USB cable with power and data channels. The controller comprises a boost circuit, a microcontroller 11, and a drive circuit. The latter provides power and control signals via a cable and proprietary plug to the nebulizer head. These signals provide power and control for a vibrating membrane receiving a liquid to be aerosolized. The controller has a housing with LED status lamps, and an ON/OFF button. The controller can be controlled via a host, either locally or remotely.

    摘要： 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.
