Abstract

La présente invention concerne un circuit d'anesthésie utilisé dans un appareil d'anesthésie inhalatoire, ne possédant pas de points de stagnation de gaz du fait de l'utilisation d'une turbine (18) et d'une valve de régulation de pression, outre un réservoir à tube long (19) à écoulement laminaire en contact avec l'air extérieur.
