The dummy includes a teat (2) made from a deformable material surrounded by a collar (3) in a plane perpendicular to the axis of the teat. The has includes a ring (4) which may be used as a handle or a means of suspension when not in use. The collar (3) houses a temperature sensor (6) located such that it is in contact with the furrow under the nose and is also in the nasal airstream. The sensor is a heat conductor and heat flows along circuits (7) to a display (8) incorporating thermosensitive crystals. |
