一种可计量宫口测量器的设计及应用

Design and Application of Cervical Dilation Measurement Device

目的为临产妇和产科医生提供一种无创、方便、客观、准确的宫口开大测量装置。方法通过两个柔性测量指环和位于两个测量指环间的测量尺完成宫口测量,测量方法符合临床常规宫口测量习惯且不受测量时手掌形变及阴道特定生理弯曲角度影响,准确测量宫口开大距离。结果在产前宫颈变化与产道关系模型中使用宫口测量器测量比徒手测量准确度高,测量结果客观可靠。结论可计量宫口测量器可较准确测量临产妇宫口开大距离,为临床提供了一种简便、客观、无创的宫口测量方法。

Objective To design a noninvasive,convenient,objective and accurate measurement device for cervical dilation for parturients and obstetricians.Methods The cervical dilation was measured by two flexible measuring rings and a measuring ruler located between the two rings.The measurement method was consistent with the clinical practice and was not affected by the palm deformation and vagina physiological bending angle,so the distance of cervical dilation could be accurately measured.Results The measurement of cervical dilation was more objective and accurate than traditional vaginal examination without cervical dilation measurement device in the prenatal cervical changes and birth canal model.Conclusion The distance of cervical dilation can be relatively accurately measured by cervical dilation measurement device.It provides a simple,objective,noninvasive way for clinical measurement of cervical dilation.
