Cervix and vagina to simulate dilation, evasion and position of the cervix.
The diagnosis of labor is made based on the assessment of uterine dynamics and also on the examination of the obstetric vaginal touch examination, which is used to identify effacement, consistency and cervical dilation, the presence or absence of the amniotic sac, feeling its integrity or rupture, the height of the presentation, the variety of the position and the determination of the attitude from the maternal bony pelvis.
From this with all this information, the obstetric examination allows you to monitor the labor. Thus, it is important to train and perceive these characteristics and stages of the process, and the use of simulators for this preparation can be very useful.
The proposed models aim to help students and those interested in building this knowledge and practice.
Construction
Materials
– 1 Styrofoam sphere – 75mm diameter
– 1 EVA paper
– 1 thin pantyhose
– 50g of EVA dough
– hot glue
– Scissors
– Large medicine tube
Instructions
1. To assemble the simulator, it is necessary to cut the medicine tube at both ends, leaving them open on both sides, this will be the part that will simulate the vaginal canal. After that, cut the styrofoam sphere in half, we will only use one half. In this half, make a round cut in its center, a hole that will simulate the opening of the cervix, so it must be cut according to the size of the desired dilation. Still in this half sphere, it should be covered with EVA paper. For the 70mm sphere, cut the EVA paper into a 15x15cm square. Then, iron the EVA paper with a hot iron until it heats up and quickly place it on top of the Styrofoam half sphere, pulling firmly to shape it to the size of the sphere as it cools.
2. After it takes the shape of the mold, cut the excess EVA that was pulled out of the sphere. Hot glue the edge of the contour between the EVA and the Styrofoam half sphere. Also remember to cut the EVA paper so that the cervix orifice is accessed. In this hole, the EVA mass must be placed, which will represent the consistency of the cervix during the digital examination.
3. After building these parts of the simulator, they must be put together. For this you need to put them inside the sock. First, place the half sphere up to the end of the sock, with its larger opening facing downwards and the hole facing upwards. Soon after, the tube is placed, centralizing the representation of the cervix orifice at one of its ends. After that, the excess sock is cut and to better fix it to the simulator, its margins can be glued to the inside of the tube.
4. Thus, the consistency simulator for the obstetric touch will be ready. This perception can be felt from the simulation of touch when placing the fingers through the vaginal canal, represented by the tube covered by the sock. At the bottom of the canal, the fingers meet the cervical wall, which will acquire a softer, smoother consistency as labor progresses. This perception of texture is comparable to that of the lip of the mouth.
