1. the detection method of tissue oxygenate and reduced hemoglobin concentration absolute magnitude is characterized in that containing successively following each step:

  • Step (1) is respectively laid a photoelectric receiving tube on two positions of biological tissue to be measured surface maintenance setting spacing, be respectively first photoelectric receiving tube (OPUS1), second photoelectric receiving tube (OPUS2);

    At an end of the extended line of above-mentioned two photoelectric receiving tube lines, the light emitting diode of laying at least three different emission wavelengths is as light source (LS), and the tube core of at least three emission wavelength correspondences is integrated in the shell;

    The centre-to-centre spacing of two photoelectric receiving tubes is at 2mm~

    10mm, and the centre-to-centre spacing of each photoelectric receiving tube and light source is at 20mm~

    50mm;

    Light source sends HONGGUANG or near infrared light;

    Step (2) detects the scattered light intensity that each photoelectric receiving tube receives according to the following steps, and calculates its optical density OD according to this, and step is as follows;

    Step (2.1) microcontroller drives above-mentioned light source timesharing and sends the light that wavelength is λ

    i, i 〉

    =3, and with first photoelectric receiving tube (OPUS1), second photoelectric receiving tube (OPUS2) is measured the scattered light intensity value of corresponding wavelength successively respectively in 0.5ms;

    Step (2.2) is utilized the computing formula of optical density, calculates different the detection under the distance, the optical density of each emission wavelength of correspondence by microcontroller
