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 knowledge and are prone to accidents. Teaching errors, the existing technology does not have simulation teaching aids for the three stages of vaginal delivery of puerpera, the teaching teacher cannot be allowed to decompose the whole process of puerpera delivery in detail, and intern midwives, interns or junior doctors cannot fully understand the dilatation of the cervix, the descent of the fetal head and the The progress of the labor process; only relying on the dictation of the teaching teacher and a small number of practical operations, it is difficult for intern nurses or junior doctors to quickly grasp and accumulate clinical experience

Embodiment 1

[0040] Maternal vaginal examination teaching mold, including support body 1 for simulating maternal pelvis, elastic bag body 2 for simulating uterus, mold body 3 for simulating fetus and trumpet-shaped conical hose for simulating cervical canal 4. The bracket body 1 includes a left bracket 11 for simulating the left half of the pelvis, a right bracket 12 for simulating the right half of the pelvis, a support rod 13 and a limit ring 15 for simulating the maternal lumbar spine; the left The front end of the bracket 11 and the front port of the right bracket 12 are respectively symmetrically hinged to the bottom of the support rod 13, and the rear port of the left bracket 11 and the rear port of the right bracket 12 are connected by an elastic strip A14, forming a joint between the left bracket 11 and the right bracket 12. The tapered outlet 111 for simulating the lower opening of the pelvis, and the two sides of the middle part of the tapered outlet 111 are respectively provided ...

Embodiment 2

[0048] The difference from Example 1 is that an interlayer is formed between the outer wall of the outlet 21 and the inner wall of the hose A22, and a ring 211 is installed in the interlayer, and Velcro A is provided at the port of the interlayer; the hose A22 is provided with There is a zipper opening 221 corresponding to the position of the ring 211.

[0049] The working principle of this embodiment is the same as that of Embodiment 1.

Embodiment 3

[0051] The difference from Embodiment 1 is that a lower plate 42 and an upper plate 43 are installed in the storage tube 41 from bottom to top; a spring 44 is installed between the lower plate 42 and the upper plate 43; The top of the upper plate 43 is connected to the tapered hose 4; the receiving tube 41 is provided with a limiting block 45 on the upper side of the upper plate 43. The pipe diameter of described receiving tube 41 is larger than the flexible tube A22 that is used to simulate puerpera's vagina, but receiving tube 41 can slide in flexible tube A22 under the action of thrust, when tapered flexible tube 4 is not pressed, spring 44 can make the tapered hose 4 rise back to the original state. Before the teaching, the tapered hose 4 and the receiving pipe 41 should be placed on the outlet 21 of the elastic bag body 2, and the tapered hose 4 is not under pressure.

[0052] The working principle of this embodiment is the same as that of Embodiment 1.

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...
