A new spectrophotometric application to amnioscopy for the estimation of the colour of amniotic fluid is presented. Three light-emitting diodes (LEDs) with peak wavelengths of 565 nm (green), 581 nm (yellow), and 645 nm (red) act as the light sources, and the light reflected from the amniotic fluid is measured using a photodiode. The greatest advantages of our new application are the short recording time of about 15 s. and the simplified mechanical performance of the measurement, which reduce errors. Preliminary clinical results show that green colouration can be easily discriminated from yellow and clear amniotic fluid. Sources of error and improvements to the method are discussed.
本文介绍了一种用于羊膜镜检查的新分光光度法应用，用于估计羊水的颜色。三个峰值波长分别为565纳米（绿色）、581纳米（黄色）和645纳米（红色）的发光二极管（LED）作为光源，使用光电二极管测量羊水反射的光。我们新应用的最大优点是记录时间短，约为15秒，以及测量的机械性能简化，这减少了误差。初步临床结果表明，绿色羊水可以很容易地与黄色和清澈羊水区分开来。文中还讨论了误差来源和该方法的改进。
