Description

Technical Field

[0001] The utility model relates to the technical field related to medical devices, and in particular to an improved membrane breaker. Background Art

[0002] High rupture of membranes refers to the operation in which the doctor punctures the amniotic sac to discharge part or all of the amniotic fluid during delivery. When labor is slow or uterine contractions are insufficient, there is too much amniotic fluid, insufficient amniotic fluid, or the amniotic fluid ruptures for too long and labor has not yet begun, the doctor performs high rupture of membranes to stimulate uterine contractions, promote delivery, and reduce the pressure of the amniotic fluid. It can also promote the regeneration of amniotic fluid and improve the growth environment of the fetus. High rupture of membranes can promote delivery and reduce the risk of infection.

[0003] Currently, conventional rupture of membranes does not require high equipment requirements, but high-level rupture of membranes requires high technology and equipment requirements. Alice forceps are currently commonly used, but it is difficult to clamp the amniotic sac membrane, and even some of the fetal hair may be clamped. In addition, it is not convenient to collect amniotic fluid after rupture of membranes, and it is difficult to observe the properties and color of the amniotic fluid. Utility Model Content
