A comminuting liquid device, a medicament delivery device, an inhaler, a method of providing droplets for delivery to the respiratory tract, a pocket-sized dispenser, and a method of mixing liquids by droplet coalescence. Liquids are subjected to electrical potentials to produce electrically charged droplets for delivery to the upper respiratory tract.

[ What is claimed is:] [1.]1. A device for comminuting liquid, comprising:a first liquid supplier having a first liquid outlet and operable to supply liquid with a resistivity in the range of 10.sup.2 to 10.sup.8 ohm meters to the first liquid outlet with a flow rate selected from 0.3 and 1.0 microl

[ What is claimed is:] [1.]1. A device for comminuting liquid, comprising:a first liquid supplier having a first liquid outlet and operable to supply liquid with a resistivity in the range of 10.sup.2 to 10.sup.8 ohm meters to the first liquid outlet with a flow rate selected from 0.3 and 1.0 microliters per second;a second liquid supplier having a second liquid outlet and operable to supply liquid with a resistivity in the range of 10.sup.2 to 10.sup.8 ohm meters to the second liquid outlet with a flow rate of 0.3 or 1.0 microliters per second;a first electrohydrodynamic comminuter for subjecting liquid issuing from the first outlet to a first electrical potential to cause the liquid to be comminuted to form a first comminution;a second electrohydrodynamic comminuter for subjecting liquid issuing from the second outlet to a second electrical potential to cause the liquid to be comminuted to form a second comminution, wherein the first aid second electrical potentials are of opposite polarity and the first and second comminutions mix to produce droplets having a diameter in the range 0.1 to 25 micrometers.
