Nebuliser

A nebuliser suitable for use in inhalation therapy, comprising:

• a wall defining a nebulising space;
• an atomizer nozzle provided in the nebulising space, having an outlet for producing a fluid mist;
• an air inlet flue, extending into the nebulising space in a direction substantially parallel to said wall, for delivering outside air to the nebulising space in the area of the outlet of the atomizer nozzle to produce a mixture of fluid mist and air, said wall being provided with an exit orifice spaced longitudinally from the atomizer nozzle for withdrawal of the mixture of fluid mist and air from the nebulising chamber;
• a nebulising space divider positioned to divide the nebulising space into a first portion in the area of the exit orifice and a second portion in the area of the atomizer nozzle, whereby the mixture of fluid mist and air flows from the second portion to the first portion for withdrawal through the exit orifice, the nebulising space divider comprising:
• an impact portion extending substantially perpendicular to a longitudinal axis of the air inlet flue and disposed around part of the air inlet flue in a shortest path between the outlet of the atomizer nozzle and the exit orifice, and defining a through passage for flow of the mixture of fluid mist and air from the second portion to the first portion;
• leading portions extending substantially parallel to the longitudinal axis of the air inlet flue from the impact portion to a position corresponding to the location of the exit orifice, and extending between the wall and the air inlet flue;
• and
• a first impact face extending substantially perpendicular to the impact portion in a direction opposite the direction of the leading portions, positioned in the nebuliser at a side of the through passage with respect to the atomizer nozzle.
