Description

[0002] At present, the determination of the in vitro pressure performance of pressure sensors mainly relies on the point pressure method or the addition of fixed weights or objects to measure the pressure or gravity changes to achieve the effect of indirect pressure detection. However, pelvic organ prolapse has its own structural particularity, involving the anterior, middle and posterior pelvic organs. Simple point and surface pressure measurement cannot truly simulate the structural changes of pelvic prolapse. If the pelvic pressure is measured from the vagina, it may be affected by the pressure generated by the upper (uterus, pelvic and abdominal cavity), anterior (bladder) and posterior (rectum) bulging. In some cases, due to the changes in the anatomical structure after prolapse, the left and right side walls may be affected, causing pressure changes on the side walls. Therefore, it is necessary to simulate the pressure from five directions. Summary of the invention
