(FR) NEBULISEUR
Abstract
(EN)
An aerosol spacer device or holding chamber comprises a chamber (1) provided at one end with an inlet to receive an aerosol cloud and at the other end with an outlet including a one-way valve comprising a support grid (7, 8) and a membrane (3), characterised in that the membrane has a central flap (10) supported at its periphery by the support grid (7, 8) such that, when the flap is lifted out of the plane of the rest of the membrane, the passage of air through the central portion of the valve is unimpeded by the support grid.
(FR)
Nébuliseur ou flacon à aérosol composé d'un flacon (1) muni à une extrémité d'une entrée pour recevoir un nuage d'aérosol et à l'autre, d'une sortie comprenant une soupape unidirectionnelle incluant une grille de support (7, 8) et une membrane (3). Celle-ci a un volet central (10) soutenu à sa périphérie par la grille de support (7, 8) de sorte que, lorsque le volet est surélevé par rapport à la surface du reste de la membrane, le passage de l'air par la partie centrale de la soupape ne soit pas entravé par la grille de support.
