Disposable amniotic fluid sampling and fetal membrane rupture device and operation method thereof

Abstract

The invention discloses a disposable amniotic fluid sampling and fetal membrane rupturing device and an operation method thereof. The device body of the disposable amniotic fluid sampling and fetal membrane rupturing device comprises a membrane suction nozzle, a negative pressure membrane suction lumen, an excessive amniotic fluid blocking sleeve, a negative pressure access air nozzle and a positioning clamping structure according to functions; the membrane suction nozzle can effectively separate the scalp and the fetal membrane of a baby through infiltration and inflow of amniotic fluid; therefore, a fetal membrane amniotic fluid sac is formed and tightly attached to the interior of a negative pressure membrane suction sac cavity of the membrane suction nozzle; the excessive amniotic fluid blocking sleeve comprises a negative pressure channel communicated between the negative pressure membrane suction lumen and the negative pressure access air tap, and can prevent the amniotic fluid in the negative pressure membrane suction lumen from excessively flowing out through the negative pressure channel; a puncture needle point of the sampling and membrane rupture syringe assembly can move in the negative pressure membrane suction lumen through the positioning clamping structure to puncture a fetal membrane and extract amniotic fluid. The membrane rupture device has the functions of extracting pollution-free amniotic fluid samples and safely and conveniently rupturing membranes before delivery, and is simple in overall structure, convenient to operate, safe and non-invasive.

Description

technical field [0001] The invention belongs to the field of obstetrical medical devices, and more specifically relates to a disposable amniotic fluid sampling and membrane rupture device and an operating method thereof. Background technique [0002] During the natural delivery process of the parturient, human intervention is often required, and obstetric medical staff perform artificial membrane rupture, that is, the fetal membrane at the cervix is ​​torn manually. Artificial rupture of membranes is a relatively common midwifery method during natural childbirth. The role of artificial rupture of membranes is mainly reflected in two aspects: first, observing the color and properties of amniotic fluid is conducive to pre-determining follow-up medical treatment plans; second , which is beneficial to strengthen uterine contractions, speed up the labor process, reduce maternal physical exertion, and help mothers to give birth naturally. [0003] At present, there are mainly thr...

AI Technical Summary

Problems solved by technology

The current artificial membrane rupture devices are crude, outdated, low in reliability, and have many problems and deficiencies, which can no longer meet the requirements of safety, convenience, accuracy, efficiency and reliability. There are defects or technical bottlenecks that have not been broken through. So far, there has not been a safe, convenient, efficient, reliable, and practical prenatal amniotic fluid sampling and membrane rupture device on the market.
