Description

Obstetrical membrane-breaking amniotic fluid drainage device

Technical Field

The invention relates to a drainage device, in particular to a membrane-breaking amniotic fluid drainage device for an obstetrical department.

Background

The artificial rupture of the membrane is one of the commonly used methods for induction of labor and induction of labor in obstetrics, the rupture of the membrane can make amniotic fluid in the membrane flow out to change the volume of the uterine cavity, and the rupture of the membrane can also make lysosomes in amniotic cells release phosphatase to promote the synthesis of prostaglandin, thereby triggering the change of uterine dynamics to start uterine contraction. The membrane rupture can soften the cervix uteri of the lying-in woman, the expansion of the uterine orifice, the uterine contraction is strengthened, in obstetrical department, to the lying-in woman of the situation such as overdue pregnancy, extension of labor, too much amniotic fluid, etc., the most common intervention means is artificial membrane rupture, there are two kinds of artificial membrane rupture modes at present, one kind is that medical personnel stretch into the vagina with the middle and index finger of the left hand first and guide, the right hand holds the forceps holder of the tooth forceps, tears the fetal membrane, and use the finger to expand the rupture, the finger should stay in the vagina after rupture of the membrane, after 1-2 times of uterine contraction the fetal head enters the basin, take out the finger, when adopting the membrane rupture of this kind of mode, the amniotic fluid gushes out suddenly or the amniotic fluid outflows and pollutes the medical personnel' clothes; another kind is to the intravaginal drainage tube of packing into, intraductal sliding connection rupture of membranes needle, utilize the drainage tube to carry out the drainage to the amniotic fluid behind the rupture of membranes, because the diameter of drainage tube is fixed, along with fetal membrane open-ended increase, the amniotic fluid can flow from the drainage tube outside, the drainage effect of these two kinds of rupture of membranes modes is all not good, be unfavorable for the collection of amniotic fluid, and the amniotic fluid spouts or the amniotic fluid outflow not only can pollute rupture of membranes person's clothing influences the environment of hospital suddenly when rupture of membranes, it is very inconvenient, so need a novel obstetrical department rupture of membranes amniotic fluid drainage device.
