Embodiment Construction

[0017] Operating the nebulizer without liquid may result in damage to the nebulizer and / or nebulizer components. As such, it may be desirable to prevent powering the nebulizer element in the event that the nebulizer element is dry. Various embodiments are described for determining whether a nebulizer element is in contact with liquid (nebulizer element is wet) or not (nebulizer is dry).

[0018] More specifically, the invention involves measuring the impedance of a nebulizer element and comparing the measurement to a predetermined impedance value. This comparison is used to determine whether the nebulizer element is in contact with the liquid. By measuring the impedance of the nebulizer element at one or more frequencies, it can be determined whether liquid is in contact with the nebulizer element.

[0019] There are a number of situations in which nebulizer elements can potentially operate in dry conditions. For example, a liquid (eg, a liquid drug such as amikacin) may ha...

Abstract

Various arrangements for determining whether a liquid is in contact with a nebulizer element are disclosed. A nebulizer element may be energized with an electrical signal at a measurement frequency. An impedance of the nebulizer element may be measured, thereby obtaining a measured impedance value. The impedance value may be compared to a stored impedance value. Based on the comparison, it may be determined whether the liquid contacts the nebulizer element.
