Abstract
The invention concerns a nebulizer chamber for aerosol systems, which is made up of an outlet duct (21) which extends vertically to the top starting from an annular nebulised liquid passage, and an anti-spill system (24, 25) positioned between the outlet duct and the annular passage to prevent spilling of the medicinal liquid due to tilting or dropping of the chamber. The chamber also has a nebulizer nozzle with a baffle (30) to deflect the larger nebulised particles.

A nebulizer chamber for aerosol devices comprising a body (10) composed with two assembled elements (11,12) and forming:
- a bottom chamber (14) for a medicinal liquid to be nebulised;
- a duct (16) extending upwards from a bottom of said chamber, designed for the entrance of a flow of nebulising air having a top orifice (17′) and supporting a nebulizer nozzle (18);
- a through passage (19) for air entrance, open both at the bottom towards the nebulizer nozzle (18) and at the top which if needed can be metered;
- and
- an annular duct (20) around the through duct and protruding from said bottom chamber up to the outlet duct (21) of the nebulised liquid towards the user;
- characterized by the fact that the outlet duct (21) extends vertically to the top of said annular duct (20) beside the through duct (19) and that a anti-spill system (24, 25) is placed between the vertical outlet duct and the annular duct so as to prevent spilling of the medicinal liquid from said outlet duct following tilting or dropping of the chamber.
Nebulizer nozzle (18) for nebulizer chambers used in aerosol systems, made up of a hood shaped element (27) terminating in an injector nozzle at the top (29) and having a central hole (32), and a flow breaker crosspiece (33) (pisper) placed above said injector nozzle, in the central hole of said deflecting plate (baffle).
