To provide a nonlinear diagnosis and a pressure regulated oxygen therapy joint examination system which analyzes intracellular information by vibration resonance at a molecular level through human bioelectric current in particular, displays a diagnosed part onto a display screen, and executes pressure regulated oxygen therapy corresponding to discovery of an ahead sickness and its prevention, as regards the nonlinear diagnosis and the pressure regulated oxygen therapy joint examination system.

A nonlinear diagnosis method is performed via a cloud, and the nonlinear diagnosis method constituting a joint examination system is implemented by a molecular resonance imaging technology. A nonlinear diagnosis apparatus 1 comprises a head scanner 15, a CPU unit 14, an image display unit 10, an operation part 13, and a detection evaluation unit 16. The evaluation signal of the detection evaluation unit is stored in a CPU unit or a memory on the cloud again as a bio-feedbacck signal. A user wearing the head scanner receives the pressure regulated oxygen therapy in a state in which the user is seated on a reclining chair placed in a pressure regulated oxygen chamber 2.
