The invention relates to a device for atomising fluids and having a bottom part (1) and a top part (2) disposed so as to be axially symmetrical with the bottom part, and comprising an intake air arrangement (3) and an outlet nozzle (4). The atomiser according to the invention also has an insert (5) for receiving a fluid (23) and a nozzle arrangement (6) disposed so as to be axially symmetrical with the intake air arrangement (3). The intake air arrangement (3) has a hollow cylindrical duct (7) with a conical widening (8) towards the incoming air end. As a result of being constructed according to the invention, the atormiser is particularly suitable for local inhalation anaesthesia, e g. in preparation for examination of the bronchi.

[ What is claimed is:] [1.] A device for atomizing fluids for inhalation, comprising:a top portion having a generally cylindrical body with an open top end, an open bottom end and a sidewall, with an atomized fluid outlet defined in the sidewall;a generally cylindrical air intake duct extending from the top end of the cylindrical body toward the bottom end of the cylindrical body, positioned substantially coaxially with the cylindrical body and having a smaller diameter than that of the cylindrical body so as to define an annular passage between an outer surface of the air intake duct and an inner surface of the cylindrical body for delivery of atomized fluid to the outlet, said air intake duct having a top end defining an air inlet opening and a bottom end defining an air outlet opening;an atomizing nozzle positioned substantially coaxially with the air intake duct near the air outlet opening, the atomizing nozzle being adapted for communication with a source of compressed gas;an insert for supplying fluid to be atomized to the nozzle, positioned adjacent the bottom end of the top portion; anda generally cylindrical bottom portion for maintaining the insert in position, positioned substantially coaxially with the top portionwherein the top portion and the air intake duct have a length and diameter such that atomized fluid particles having a size suitable for delivery to a vicinity of bronchia, throat and glottis of a patient are delivered to the atomized fluid outlet via the annular passage upon inhalation by a patient through the atomized fluid outlet.
