1. An optimal diagnosis point detector for noninvasive diagnosis of blood constituents in a patient'"'"'s bloodstream comprising:

  • a detecting unit for generating an input signal to irradiate a portion of the patient to be diagnosed and for detecting at least one of a predetermined signal that has passed through a portion of a patient'"'"'s bloodstream to be diagnosed and a predetermined signal that has been reflected from said portion to be diagnosed, said detecting unit also for outputting an output signal representative of characteristics in the patient'"'"'s bloodstream;

    a driving unit for driving said detecting unit;

    an amplifier for amplifying the output signal of said detecting unit;

    an analog-to-digital converter for receiving a signal output from said amplifier and converting the signal output from said amplifier into a digital detected value;

    a storage unit for storing a predetermined optimal diagnosis point detecting method;

    a command inputting unit through which a user'"'"'s command is input;

    a central processing unit, connected to said driving unit, said analog-to-digital converter, said command inputting unit, and said storage unit, for performing said predetermined optimal diagnosis point detecting method stored in said storage unit according to the user'"'"'s input command; and

    a display unit connected to said central processing unit for displaying said digital detected value and displaying an indication that said digital detected value is a maximum value when a maximum detection signal is detected from said detecting unit.
