A new method using two intraluminally placed ultra-miniature pressure sensors placed in the same isthmus of the oviduct has been developed for continuous monitoring of oviductal pressure variations during the oestrous cycle in unrestrained gilts. Each test animal was followed for 48 h during which recordings were made at frequent intervals. By using two points of registration, directions of pressure waves could be determined. This technique allows for the determination of the base pressure in the oviduct and how it varies during the oestrous cycle. Effects of different stimuli and the effect of narcosis on oviductal activity can also be directly studied.
已开发出一种新方法，即在输卵管的同一峡部放置两个腔内超微型压力传感器，用于连续监测未束缚小母猪发情周期中的输卵管压力变化。对每只试验动物跟踪48小时，在此期间频繁进行记录。通过使用两个记录点，可以确定压力波的方向。该技术可用于确定输卵管的基础压力及其在发情周期中的变化情况。还可以直接研究不同刺激的影响以及麻醉对输卵管活动的影响。
