Non-invasive uterine activity sensor |
摘要 |
Uterine activity is sensed by passing light through the patient's abdominal wall and detecting the light reflected from abdominal tissues. The intensity of the reflected light varies with the state of contraction of the patient's uterus. The use of light for monitoring uterine activity avoids the problems of size, fixation, and measurement accuracy exhibited by the conventional tocodynamometer technique.
