L'invention concerne un dispositif (2) de décontamination pour une enceinte de confinement (1) et/ou de produit de traitement pouvant être introduit dans celle-ci, comprenant un réservoir (R) qui est destiné à stocker un agent de décontamination (8) liquide dans les conditions normales. Le dispositif (2) comprend en outre un pulvérisateur (V) soumis à l'action d'une source d'air comprimé (9), servant à la pulvérisation de l'agent de décontamination (8) dans un aérosol. Le dispositif (2) présente au moins une sortie (55) qui est prévue pour l'introduction directe de l'aérosol produit dans le dispositif (2), dans ladite enceinte de confinement(1). Le réservoir (R) est rempli, en cours de fabrication, avec l'agent de décontamination (8), ou bien peut être rempli avant usage, par l'utilisateur. L'ensemble du dispositif (2), ou au moins le réservoir (R) est prévu en tant qu'article à usage unique. Le pulvérisateur (V) est réalisé sous la forme d'un tube venturi, dans lequel débouche un canal primaire (20) qui conduit au réservoir (R). Dans le réservoir (V) débouche un canal secondaire (35) qui présente un raccordement (34) à la source d'air comprimé (9). La quantité de remplissage dans le réservoir (R) est déterminée pour un volume défini d'une enceinte de confinement (1).
