• cervical dilation

  In order to replace the conventional method of vagina palpation which has been widely used in obstetrics,a new method for detecting fetal head position and cervical dilation automatically is proposed based on the analytic geometry of space and ultrasonic triangulation.

  基于空间几何原理和超声多普勒三角测量法,提出了一种胎头位置、宫颈扩张的自动测量方法,以替代产科临床使用的传统手工触诊法。

• cervix dilation

  The system employs a special sensor to measure cervix dilation. The descending of fetal head is obtained by software table look-at according to the relationship between cervix dilation and descending of fetal head.

  产程宫颈扩张参数的大小是通过电位器钳式子宫颈开口监测传感器来获得;胎头下降程度是依据产程图中胎头下降曲线与宫颈扩张曲线之间存在的恒定关系通过软件查表来确定。
