Parturient obstetric apparatus for gynaecology and obstetrics department

Abstract

The invention discloses a parturient obstetric device for gynaecology and obstetrics department, belongs to the field of obstetric devices,. According to the parturient obstetric device for gynaecology and obstetrics department, the inflation and expansion speed is not too high when an air bag is used for expanding a birth canal through a double-layer air bag structure of an outer sealing air bagand an inner semi-permeable air bag. The condition that the birth canal expansion speed is too high, and a lying-in women feels uncomfortable, can be avoided effectively. In the later stage of birth canal expansion, after the outer sealing air bag and the inner semi-permeable air bag are separated, under the action of an expansion pressing ring, air gradually enters the space between the outer sealing air bag and the inner semi-permeable air bag, and at the moment, under the action of the air, two sides of the expansion pressing ring extend and squeeze towards the inner wall of an annular ballgroove, so that the air squeezing force becomes larger and larger along with gradual increase of air, the effect that the connecting strength and the sealing performance of the outer sealing air bagand an air pressure ring become higher and higher can be achieved, the situation of air leakage or falling off of the air bags is effectively avoided, and the safety during the whole obstetric processis effectively improved.

Description

technical field [0001] The invention relates to the field of obstetrics and gynecology, and more specifically, relates to an obstetrics and gynecology delivery aid. Background technique [0002] Midwifery device, a kind of midwifery device for obstetrical midwifery, which is easy to operate, can reduce head injury and speed up delivery.
