Low-harm amniocentesis sampling method for gynaecology and obstetrics

Abstract

The invention discloses a low-harm amniocentesis sampling method for gynaecology and obstetrics, and belongs to the technical field of amniocentesis sampling. According to the low-harm amniocentesis sampling method, an Internet of Things technology is used to assist a part of gynaecology and obstetrics doctors lack of experience and help the doctors determine related data such as needle insertionpoints and needle insertion heights, real-time feedback is provided for the doctors through a system composed of a control terminal, a distance sensor and a signal lamp, the accident that the needle inserting angle does not conform to expectation is not likely to happen, an illumination lamp set arranged on a needle tube body can effectively increase illumination of needle inserting areas, the doctors can find needle inserting points conveniently, finally, targeted accompanying is provided for subsequent accompanying work of pregnant women through the Internet of Things technology, the accident that amniotic fluid sampling fails due to less clinical experience of doctors is not likely to happen, fetuses are not likely to be injured, and the accidents of fetus abortion and pregnant women injury are not likely to happen.

Description

technical field [0001] The invention relates to the technical field of amniocentesis sampling, in particular to a low-harm amniocentesis sampling method for obstetrics and gynecology. Background technique [0002] Amniocentesis is a method of prenatal diagnosis, generally suitable for prenatal diagnosis in the second trimester. What is amniocentesis—Under the guidance of ultrasound, a long and thin needle is passed through the pregnant woman's belly, uterine wall, and enters the amniotic fluid cavity, and the process of extracting some amniotic fluid is called "amniocentesis". [0003] The best time for amniotic fluid extraction by puncture for prenatal diagnosis is 16 to 24 weeks of pregnancy. Because the fetus is small at this time, the amniotic fluid is relatively large, the fetus floats in the amniotic fluid, and there is a wide amniotic fluid band around it. When the amniotic fluid is extracted by needle puncture, it is not easy to stab the fetus. Take 20 ml of amnioti...

Problems solved by technology

[0005] The ratio of various risks in the process of amniocentesis sampling is 1 / 250-1 / 300, usually there may be bleeding, miscarriage, infection, amniotic fluid leakage, damage to the fetus, etc., and if the pregnant woman has uterine malformation, uterine fibroids, amniotic fluid volume Amniocentesis may fail. For some experienced obstetricians and gynecologists, amniocentesis sampling is only a method with a high safety factor. For some obstetricians and gynecologists with less experience, for some For pregnant women who are not correct or have certain diseases themselves, amniocentesis sampling is likely to fail due to insufficient on-the-spot response, and it is easy to cause damage to the fetus, and even cause accidents of fetal miscarriage and injury to pregnant women.
