Certainly, some membrane breakers exist at present, for example, a membrane breaking needle is fixedly arranged on the inner wall of the front end of a membrane breaking cylinder, and an amnion is adsorbed to be attached to the front end of the membrane breaking cylinder by using a push rod with a piston so as to puncture the amnion, on one hand, the size of a broken opening cannot be controlled in such a way, and if the broken opening is too small, the difficulty is very high when a secondary broken opening is needed; if the laceration is too large, amniotic fluid flows out rapidly and a large amount, which causes sudden drop of intrauterine pressure and easily leads to early placental peeling. Moreover, the flow of amniotic fluid cannot be controlled by the membrane rupture device, and the large rupture opening in clinic requires a doctor to manually block the rupture opening, so that time and labor are wasted, and the amniotic fluid is difficult to collect, so that the amniotic fluid pollutes the intrauterine environment of a puerpera, even the amniotic fluid is caused to be embolism, and the life of the puerpera is threatened. Therefore, it is desirable to provide a membrane rupturing device for obstetrics and gynecology department to solve the above problems.

For example, when the second getter pump 128 is operated, the inlet 1281 of the second getter pump can suck air from the outside and inflate the inflatable cuff 129 through the outlet 1282 of the second getter pump, thereby inflating the inflatable cuff 129. When the inflation sleeve 129 needs to be exhausted, the operation of the second suction pump 128 can be stopped, and the air hole connecting the inflation sleeve 129 and the first space is opened, so that the inflation sleeve 129 contracts under the pressure of the amniotic fluid and exhausts the air to the first space, and the inflation sleeve 129 contracts by utilizing the through hole arranged at the tail part of the first space and communicated with the outside. Of course, an additional suction pump may be disposed to suck the air in the inflation sheath 129 to the outside, which is not limited herein.
