Artificial membrane rupture device for obstetrics and gynecology department

Abstract

The invention discloses an artificial membrane rupture device for obstetrics and gynecology department in the technical field of medical instruments, which is provided with an extending tube, an inner tube shell is fixedly connected to the inner side wall of the extending tube, a connecting cavity is formed between the extending tube and the inner tube shell, and the connecting cavity is movably connected with a first connecting tube; an extension spring is fixedly connected between the inner side of the top wall of the first connecting pipe and the outer side of the top wall of the inner pipe shell, the lower end of the extending pipe is integrally connected with a scratching edge, the scratching edge is of an annular protruding structure, a tip is formed at the protruding position, the top wall of the inner pipe shell is connected with one end of a pressing rod, and the other end of the pressing rod penetrates through the top wall of the first connecting pipe. A user stretches the stretching tube from the pudendum of a puerpera until the scratching edge is in contact with the fetal membrane, at the moment, the pressing rod is pressed to enable the scratching edge to puncture the fetal membrane. Meanwhile, the fetal membrane can be completely scratched through slight rotation, the extension spring plays a certain role in pressing the hand pressing force of the user so as to prevent the pressing force from being too large. The device can be used for quickly and safely rupturing the fetal membrane and is easy and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of medical devices, and the specific field is an artificial membrane rupture device for obstetrics and gynecology. Background technique [0002] The fetal membrane is commonly known as the afterbirth. The amniotic fluid and urine water in the fetal membrane combine to form fetal fluid. The fetal fluid functions as anti-adhesion, lubricant, buffer, and anti-compression impact. When women are pregnant, they need to rupture the membranes for delivery. The membrane rupture methods are divided into natural membrane rupture and artificial membrane rupture. The artificial membrane rupture operation steps: when the dilation of the cervix is ​​≥ 3cm, there is no head-pelvis, the fetal head has been connected, For those without umbilical cord prolapse and placenta previa, check the cleanliness of the vagina, perform a vaginal examination under strict disinfection, and insert the middle and index fingers of the left ha...
