Background

Obstetrics and gynecology are one of four main subjects of clinical medicine, and the delivery assistance refers to a series of measures taken before and during labor to ensure that a fetus is delivered out of a maternal birth canal smoothly, and mainly comprises the steps of caring for the parturient, carefully observing the labor course, guiding the parturient to be matched with the labor course and delivering, and developing some parturients who are not suitable for labor when the parturient is delivered due to combined diseases in the production process, so that the parturient is difficult to shorten the labor course as soon as possible. The fetal head suction is to put the external mouth of the suction apparatus on the exposed fetal head, then to suck out the air in the suction apparatus by the injector to form a negative pressure area, and to suck the fetal head by the negative pressure suction principle, and to deliver the fetal head by matching with the uterine contraction.

The existing obstetric apparatus has various types, various functions, complex operation and high manufacturing cost, increases the use cost for some common obstetric hospitals, is not beneficial to the skilled grasp of workers, increases the labor intensity of the workers, causes long obstetric time, troublesome operation, time and labor waste, and greatly increases the work difficulty of medical staff; and some suction heads for sucking the fetal head have poor toughness, so that the bad influence of some injuries on the fetal head can be caused, air leakage can also occur in the suction process, and the suction stability on the fetal head is influenced.
