Pregnant and lying-in woman vagina examination teaching mold and using method thereof

Abstract

The invention discloses a pregnant and lying-in woman vagina examination teaching mold, which belongs to the technical field of obstetric teaching aids, simulates a pregnant and lying-in woman pelvisthrough a support body, simulates a pregnant and lying-in woman uterus through a transparent elastic bag body, simulates a fetus to be delivered through a mold body, and enables students to visually experience measurement in the pelvis on the teaching aids in clinical teaching. Under operation by a teacher, the three parturition processes of parturition of a puerpera are simulated, so that students can better and quickly achieve the purposes of expected clinical practice and clinical experience accumulation by combining theories with clinical teaching. The elastic bag body is provided with anopening for a teacher to stretch a hand into to push the mold body, and an outlet is formed to simulate a uterine orifice, so that students can conveniently perceive the process from uterine orifice expansion to uterine orifice fullness in the simulated birth process; the support body is divided into the left support and the right support, the front ends of the left support and the right support are hinged, and the rear ends of the left support and the right support are connected through the elastic rubber strip A. In the process of pushing the die body to slide downwards, the uterine dilatation situation can be well simulated, the whole delivery process of a puerpera is fitted, students are impressed deeply, and teaching content can be better mastered. The teaching aid not only can avoidreducing the number of times of vaginal examination on a patient repeatedly due to teaching in clinic and reduce the risk of upward infection of the patient, but also can reduce discomfort and medicaldisputes caused by teaching in the delivery process of the patient.

Description

technical field [0001] The invention belongs to the technical field of obstetrical teaching aids, and in particular relates to a teaching mold for vaginal examination of pregnant women and a method for using the same. Background technique [0002] There will be three stages of labor in a normal vaginal delivery. The first stage of labor is also called the cervical dilation stage, which refers to the beginning of labor until the cervix is ​​fully dilated (10cm). The important sign of labor is the presence and gradual strengthening of uterine contraction, which lasts for 30 seconds or more, with an interval of 5-6 minutes, accompanied by progressive disappearance of the cervical canal, dilatation of the cervix, and decline of fetal presentation. The first stage of labor is divided into the latent period and the active period. The latent period refers to the period from regular uterine contractions to dilation of the cervix <5 cm. The active phase refers to the expansion of...

Problems solved by technology

[0003] In the usual training for trainee midwives, interns or junior doctors, the teacher directly inspects and teaches the maternal vagina, and the trainees stand next to the teacher to observe, while the pelvic and transvaginal inspections of the dilation of the cervix and the descending position of the fetal head are subject to inspection times and clinical Experience limitations, such as repeated practice on puerpera will cause discomfort to the puerpera itself and easily lead to medical disputes, and students cannot understand the teaching content well. Intern midwives, interns or junior doctors are slow to master the teaching knowl
