The invention relates to an apparatus and a method for identifying containers containing different anesthetic fluids. The containers include at least a fluid chamber (2) for an anesthetic fluid and for vaporizing the fluid therefrom into a gas chamber (3). A connecting element (8) is used for coupling the container with a conduit (6) extending to a patient for supplying an anesthetic to a patient. The containers containing anesthetic fluids are designated or labelled distinctly from each other by means of at least one magnetic-field producing element (12). The presence of this element is in turn detected by means of a magnetic-field detecting element (13) . The identification of a container containing an anesthetic fluid and, thus, an anesthetic fluid contained therein is effected by means of an identification element (15), which receives a signal from one or more magnetic-field detecting elements. The invention further relates to a method and an apparatus for detecting a connection between an anesthetic fluid container and a conduit (5 or 6) extending to a patient. According to the invention, a container containing an anesthetic fluid is designated or labelled by means of a magnetic-field producing element (12) and the presence of said element or the direction of a magnetic field produced thereby can be detected by means of a magnetic-field detecting element (13), said detection being used as a basis for establishing whether the container is coupled in its position. <IMAGE> |
