Dispensing device
First Claim
1. A dispensing device comprising an exposed, unshielded comminution site, means for supplying liquid to the comminution site, means for charging the comminution site to a potential for causing electrohydrodynamic comminution of liquid supplied to the comminution site, a discharge electrode for at least partially discharging comminuted matter, means for charging the discharge electrode to a polarity opposite to that of the comminution site to cause ionization of gaseous molecules in the vicinity of the discharge electrode, the discharge electrode being arranged so as to face towards the comminution site to cause gaseous ions produced by the discharge electrode to be directed towards the comminution site to at least partially discharge comminuted matter produced by the comminution site.

Abstract
A device for dispensing a liquid for inhalation, which comprises an unshielded electrohydrodynamic comminution means (1), a means for supplying a liquid to the comminution means, a sharp discharge electrode (12) and, optionally, a means for charging the discharge electrode to a polarity opposite to that of the comminution means, wherein the discharge electrode is located so as to direct gaseous ions into the body of the comminuted liquid and thereby to fully or partially discharge the comminuted liquid.
