胎动信号
1.
At first FMS is decomposed by wavelet,then its reference signal is chosen from the size which is independent of the interference in the fetal movement signals(FMS), The self-adaptive filter can not only wipe off the low-frequency interference brought by breath and womb movement but also restrain the high-frequency interference brought by cough and laugh.

补充资料：胎动
胎动
fetus movement
胎儿在母体子宫内活动称为胎动。孕妇可于妊娠18～20周开始自己感到胎动存在，故自觉胎动存在是诊断中期妊娠的一个重要体征。同时胎动又是胎儿情况良好的表现。因此，临床上可利用监测胎动了解胎儿宫内安危情况。胎动每小时3～5次，随着妊娠周数增加，胎动越活跃。孕28～37周达高峰，38周以后逐渐减少。由于胎儿的活动量各异，不同孕妇自我感觉胎动差异很大，多数报道每日几十次到百次左右。一般认为，12小时内的胎动量累计数不得少于10次。如果12小时内胎动数少于10次或总数下降超过孕妇本人胎动数50%而又不能依靠声、光、刺激或腹部活动而恢复，应视为胎盘功能不良，胎儿在子宫内缺氧。胎动减少是胎儿窘迫的一个重要指标，故临床上于妊娠晚期让孕妇自数胎动可了解胎儿在宫内安危状态。胎动后常出现胎心加速的反应，故胎儿监护时利用胎动后胎心加速反应了解胎儿宫内储备状态。胎动消失后，胎心在24小时内也会消失，故应注意这点以免贻误抢救时机。另外，胎动过频往往是胎动消失的前驱症状，也应给予重视。
