Description
Technical Field
The invention relates to the technical field of gynecological teaching devices, in particular to a visual teaching model for converting a delivery machine into a visual teaching model.
Background
The delivery machine refers to the process of delivering the fetal presenting part passively through a series of rotations that accommodate the pelvic plane, with its smallest radial line passing through the birth canal. Wherein, the delivery machine is divided into the following steps: linking, descending, bending, inward rotation, upward extension, resetting and outward rotation, and delivering the fetus; in particular, the method comprises the steps of,
And (3) engagement: the double-top meridian of the fetal head enters the plane of the pelvis inlet, and the lowest point of the fetal head skull approaches or reaches the level of ischial spines;
and (3) descending: the action of advancing the fetal head along the pelvic axis, called descent; the most important factor for promoting fetal head descent is uterine contractility;
Bending in depression: when the fetal head descends to the pelvic floor, the resistance of the levator ani muscle is met, the fetal head in the half-depression state is further depressed by means of leverage, and the minimum diameter line of the fetal head and the diameter of the pre-occipital chimney are adapted to the minimum diameter line of the birth canal, so that the fetal head can be continuously descended;
Inner rotation: the fetal head rotates to adapt to the longitudinal axis of the pelvis, so that the sagittal suture of the fetal head is consistent with the anterior-posterior diameters of the middle pelvis and the pelvis outlet and is called internal rotation; the internal rotation is completed before the end of the first labor. Whether the internal rotation is smooth is closely related to the contraction force and is related to the progress of the second labor;
upward extending: after the fetal head completes internal rotation, when reaching the pudendum external orifice, the force of production forces the fetal head to descend, and the force of the pelvic floor levator ani contraction pushes the fetal forward, and both act together to enable the fetal head to turn upwards along the downward and forward direction of the lower section of the pelvic axis, and when the lower occipital bone of the fetal head reaches the lower edge of pubic symphysis, the fetal head is gradually restrained and stretched by taking the pubic arch as a fulcrum, and the fetal head top, the forehead, the nose, the mouth and the face are sequentially delivered out;
resetting and external rotation: when the fetal head is delivered, the fetal head needs to turn left or right for 45 degrees, so that the fetal head and the fetal back are in normal relation, and the fetal head is called resetting; when the shoulder descends and rotates inwards in the pelvis, the pillow part continues to rotate for 45 degrees outwards, which is called external rotation; the fetal shoulders are turned into the direction consistent with the front and rear diameters of the pelvis outlet, so that the delivery of the shoulder is facilitated;
shoulder delivery: shoulder delivery is the second joint after the head delivery, should deliver the front shoulder first, then deliver the back shoulder, after the both shoulders delivered, the child body and four limbs will be delivered smoothly.
