Low load and real-time monitoring of bladder urine automatic warning method

A low-load and real-time monitoring of bladder urine automatic alarm method, comprising the steps of: 1) a plurality of test electrode against a test site of a patient, according to the bioelectrical impedance measured by real-time electrical impedance bladder bioelectrical impedance measuring apparatus value; 2) by means of digital filtering algorithm, select the appropriate parameters, the interference signal is removed, increase the electrical impedance signal to noise ratio; then, real-time updates the maximum electrical impedance, calculated impedance and rate of change threshold; 3) the medical knowledge and clinical tests experience, the establishment of expert diagnostic system that is impedance threshold, the threshold rate of change fuzzy processing, development of fuzzy rules; then automatically voiding alarm criterion according to the fuzzy rules, or to prompt patients to urinate promptly notify the medical staff. The method of the present invention, real-time, accurate prediction of the dynamic bladder urine volume and urinary alarm to remind the patient to urinate in time, or remote monitoring of the disease through the wireless network, operation more safe and convenient, the effect of anti-interference.
