Abstract
A nasal fluid-spray device having: a reservoir containing at least one dose (D) of fluid; and a dispenser system that, each time the device is actuated, sprays a dose (D) of fluid through a spray orifice, generating a spray that extends axially from the spray orifice. The device further includes a generator system for generating a secondary flow, which generator system is actuated simultaneously with the dispenser system, the secondary flow generator system having a secondary flow channel provided with an outlet orifice, the outlet orifice arranged downstream from the spray orifice, and the secondary flow extending from the outlet orifice along an axis (B) that forms an angle (α) relative to the axis (A) of the spray and that intersects the axis (A), thereby deforming and/or deflecting the spray.
