1. An anesthesia machine connectable to a selected one of a plurality of patient breathing circuits, the patient breathing circuits having one or more conduits providing differing characteristic gas flow paths for supplying fresh gas containing an anesthetic agent and for supplying and receiving breathing gas to and from a patient, said anesthesia machine comprising:

  • an anesthesia delivery unit (10) having ports (34, 36) providing and receiving breathing gases for the patient and providing the fresh gas containing an anesthetic agent;

    a flow sensor module (26), said flow sensor module having ports (28, 30) suitable for connection to the conduit or conduits of a selected one of the plurality of patient breathing circuits;

    a selected one of a plurality of interchangeable patient circuit modules (12) provided in accordance with the selected one of the plurality of patient breathing circuits, said selected patient circuit module being interposed intermediate said anesthesia delivery unit and said flow sensor module, said selected patient circuit module containing flow paths extending between said anesthesia delivery unit and said flow sensor module for establishing the characteristic breathing gas and fresh gas flow paths for the selected one of the plurality of patient breathing circuits; and

    a detector for providing an indication of which one of the plurality of patient circuit modules is interposed intermediate said anesthesia delivery unit and said flow sensor module, said detector comprising first means (38) mounted on said patient circuit module and second means (40) mounted on said anesthesia delivery unit, said first and second means being so mounted on said patient circuit module and said anesthesia delivery unit, respectively, as to be brought into proximity with each other when said patient circuit module is interposed intermediate said anesthesia delivery unit and said flow sensor module, said first and second means coacting when in proximity with each other for providing said indication.
