Technical Field
The utility model relates to the technical field of medical equipment, specifically a gynaecology and obstetrics uses amnion rupture of membranes sampling equipment.
Background
The amnion is used as the innermost layer of the fetal membrane, in the pregnant woman, the fetus is in a sac cavity formed by the amniotic sac, amniotic fluid is filled in the sac cavity, and the fetus is suspended in the amniotic fluid of the amniotic sac during the whole development process of the mother. During delivery, the fetal membranes are broken at proper time, and delivery can be completed, so that the fetus is smoothly separated from the mother body. The fetal membrane sac has certain thickness and strength, and when the fetal membrane is broken during the delivery of the pregnant woman, the determination is difficult; some lying-in women have bad uterine contraction in the midwifery, and the uterine contraction needs to be promoted by artificial rupture of membranes; when breaking membranes, the midwife generally opens the fetal membrane sac by external force to shorten the labor process and ensure the smooth production of the fetus and the safety of women and children. In the existing membrane rupture mode, a midwife usually uses a sharp instrument such as a needle and the like to cut (cut) a fetal membrane sac through an obstetric canal.
The prior art has the following problems in use: firstly, the birth canal is narrow, the vision is difficult to observe and judge, the operation is completely dependent on hand feeling, the depth is not easy to master, and the operation is inconvenient; secondly, when the fetus is delivered, the fetus is generally close to the fetal membrane sac, and when the fetal membrane is broken by sharp instruments such as a needle and the like, the fetal membrane cannot be cut slightly, so that the fetus is easily injured by mistake. And the amniotic fluid sampling examination is an important means for analyzing whether the fetal diseases and the development are normal or not, and the conventional amniotic fluid examination is generally carried out before delivery in 16-22 weeks of pregnancy. The current sampling mode is, the doctor is under the guide of ultrasonic wave, implement amniotic cavity puncture extraction, it is very troublesome and unsafe, lying-in woman's fetal membrane rupture and amniotic fluid sample set composite has been proposed in chinese patent 201920812462.1, the device can suck the amnion part from the back with the foetus, rethread tube needle breaks the membrane, and the operation is convenient, and can effectively avoid the accidental injury to the foetus, safety and reliability, when breaking the membrane, usable body and tube needle extract the amniotic fluid in the amniotic cavity, high durability and convenient use, but above-mentioned scheme is when using, need extract through multilayer sleeve, in the use, can lead to other sleeves to remove and lead to the emergence of accident situation, and the structure is complicated relatively, it is comparatively loaded down with trivial details to use, so provided an amnion rupture of membranes sampling equipment for gynaecology and obstetrics.
