Description

Real-time monitoring system and monitoring method for perineum pressure during vaginal delivery

Technical Field

The invention belongs to a medical monitoring system, and particularly relates to a real-time monitoring system and a monitoring method for perineum pressure during vaginal delivery.

Background

The perineum injury is the most common complication of vaginal delivery, the incidence rate is as high as 50-85%, and the perineum injury is mainly caused by natural perineal laceration caused by fetal head compression and extreme extension of a yin tissue during delivery or operation perineal incision for avoiding serious perineal laceration and artificial enlargement of a birth canal outlet. At present, the possibility of perineum injury in clinic evaluation is mostly determined by working experience, the subjectivity is strong, and particularly, no measurable specific numerical value and objective index exists in the decision and implementation time of perineum incision, so that the possibility of perineum injury and the necessity of perineum incision are difficult to judge. Therefore, starting from basic research, the study on the correlation between the perineal pressure and perineal injury during vaginal delivery and the determination method are very important. The correlation between the perineum pressure and different degrees of damage of the perineum can be known clinically through the perineum pressure, but relevant research reports are not seen at home and abroad at present, in the existing patent documents, CN104042224A, CN208823332U, CN109106433A, CN205459361U and US2017215945A1, although the intrauterine pressure in the antenatal and the antenatal processes are researched, the traditional pressure sensor is adopted for testing without exception, the existing pressure testing mode is not suitable for measuring the perineum pressure in the process of delivery, the fetal head is easy to slip due to the fact that the fetal head compression space is small, the fetal head is spherical, in the pressure testing environment in the actual antenatal process, the vulva is continuously contracted and expanded, the pressure sensor is easy to slip accidentally, the monitoring failure is caused, and the fixed structure of the existing pressure sensor, which adapts to contraction change, is rarely researched. In addition, the position of the proper pressure sensor can be found only by rotating the external fixing handle in the conventional pressure sensor arrangement, and the illuminating module is usually required to be arranged on the external fixing handle, so that the proper position of the sensor and the proper illuminating direction cannot be obtained.
