Portable tissue blood flow perfusion monitor based on abdominal impedance spectral parameters

The invention discloses a portable tissue blood flow perfusion monitor based on abdominal impedance spectral parameters, comprising a master control module, a programmable constant-current source, animpedance electrode array, a wide-band abdominal impedance spectral data acquisition circuit, an AD (analog/digital) converter, a buffer unit, a control panel, a display screen and a battery power supply module; when powered by the battery power supply module, the master control module controls the programmable constant-current source to output an excitation current signal of required frequency point, which is applied to the human abdomen through exciting electrodes in an impedance electrode array; the wide-band abdominal impedance spectral data acquisition circuit transmits analog values of real parts and imaginary parts of impedances corresponding to exciting frequencies to the AD converter to carry out digital-analog conversion; the converted data of real parts and imaginary parts of the impedances are transmit
