Description

Automatic fetal head traction device for obstetrical department

Technical Field

The utility model belongs to the technical field of medical auxiliary instrument, specifically relate to an automatic draw gear of foetus head for obstetrical department.

Background

The fetal head suction is a vaginal delivery aid which is characterized in that a fetal head suction apparatus is arranged on a fetal head by utilizing the principle of negative pressure, and traction or rotation is carried out after certain negative pressure is formed to assist delivery of a fetus. The method comprises the following specific steps: 1. the rubber tube is connected to the open hollow tube of the traction handle. The left index finger and the middle finger are separated from the vagina, the aspirator is held by the right hand, the lower edge of the fetal head end is firstly put along the back wall of the vagina, and then the aspirator is rotated and completely slid in until the fetal presenting part is abutted, so that the aspirator is tightly attached to the scalp. 2. The index finger and the middle finger are inserted into the vagina, and the suction apparatus is examined for a circle to determine that no soft tissue is clamped between the suction apparatus and the fetal head. 3. The operator fixes the aspirator head with both hands, and the assistant sucks the suction opening of the aspirator with an empty needle, increases the negative pressure in the aspirator head, makes the aspirator firmly adsorb on the fetal head, and clamps the rubber tube of the suction opening. 4. During the contraction of uterus, the doctor orders the lying-in woman to hold breath, and the operator holds the traction handle and pulls along the pelvis axle direction according to the childbirth mechanism. Firstly, the fetus head is drawn downwards and outwards, and when the occiput of the fetus head reaches the lower edge of the pubic symphysis, the operator lifts the suction apparatus to enable the fetus head to extend upwards to give birth. 5. When the head of the fetus is pulled out of the vaginal opening by the double apical diameters, the rubber tube is loosened to relieve the negative pressure, the suction apparatus is taken down, the delivery is assisted according to a delivery mechanism, and the tire shoulder and the tire body are delivered.

However, due to the shape of the head of the fetus or other reasons, the phenomenon that the sucker slips off frequently occurs in the traction process, the slipping affects the traction, the head traction mode cannot be continuously adopted for midwifery after the slipping is performed twice, and the influence is caused on the fetus, so that the design of the fetus head automatic traction device for the obstetrical department is very necessary.
