Change.Such as, the resistance value of hygroscopic material, formed capacitance structure after capacitance voltage value or formed inductor structure after inductance
Value etc..
Positive and negative electrode is provided with monitor 2 to 201, and positive and negative electrode is separately positioned on suction to the both positive and negative polarity in 201
Diverse location on blood medicated cushion 1, mainly for detection of the blood flow volume absorbed by the hygroscopic material that sucks blood in medicated cushion 1, its work original
Reason is the change of the electric parameter change modeling puerpera's amount of bleeding by hygroscopic material.Specifically, when puerpera's no bleeding situation, inhale
Wet stock is very dry, almost insulate, and now hygroscopic material is almost non-conductive, is almost not turned between positive and negative electrode, 2 evidence of monitor
This can determine whether out puerpera's no bleeding situation substantially；And when bleeding situation occurs in puerpera, hygroscopic material gradually becomes moistening, start
