Abstract

L'invention a trait à un vaporisateur pour anesthésie, qui comprend un réservoir (1) destiné à contenir un agent anesthésique liquide, des moyens de pressurisation (5) destinés à mettre l'agent anesthésique liquide sous pression dans le réservoir, un dispositif de vaporisation (12), et un conduit destiné à l'apport de gaz vecteur. Le vaporisateur selon l'invention est adapté de manière que, en cours d'utilisation, l'agent anesthésique liquide contenu dans le réservoir soit mis sous pression par le moyen de pressurisation, et acheminé sous forme liquide, sous l'effet de ladite mise sous pression, vers le dispositif de vaporisation, où il est vaporisé pour être administré à un patient avec le gaz vecteur, la mise sous pression de l'agent anesthésique liquide et son acheminement vers le dispositif de vaporisation étant tous deux commandés indépendamment de l'apport de gaz vecteur.
