Abstract
A sealed receptacle (1) contains the additive in liquid phase. A dip tube (3) permits sending the additive to a heating enclosure (5) in which the liquid vaporizes before being sent to a collector-mixer (11) through a constriction (10). The flow rate of additive is controlled by the pressure prevailing above the liquid in the receptacle (1) thanks to a control valve (20) connected by a pressure regulator (25) to a computer (26). This latter receives predetermined values of concentration of the mixture through an input (27). It is preferably connected to a detector (28) of the temperature of the enclosure and/or to an analyzer (30) of the composition of the mixture. Used particularly in anesthesia apparatus.
