The utility model relates to the technical field of medical instruments, in particular to an artificial membrane rupturer for obstetric clinical use.

Background technique

In the clinical practice of obstetrics and gynecology, puerperae are often encountered with uterine atony after entering the active phase, which leads to stagnation of the active phase, obstruction of the lift and lowering of the labor, and prolonged labor. Intracranial hemorrhage and cerebral palsy occur. In clinical practice, vascular forceps or needles are used to perform artificial rupture of membranes to strengthen uterine contractions. However, the current clinical technology has many disadvantages. The vagina of the mother will spread the disease. It is difficult to control the depth of the needle or vascular forceps, and it is easy to damage the fetal scalp. When the tension of the amniotic sac is high, the artificial rupture of the membrane will cause the amniotic fluid to splash the medical staff, resulting in the spread of the disease and the overflow of the amniotic fluid. Sterility requirements. At the same time, when the existing artificial membrane rupture technology is used, the flow rate of amniotic fluid cannot be effectively controlled.
