Description
Technical Field
The invention belongs to the technical field of medical instruments, and particularly relates to an automatic quantitative amniotic fluid extracting device.
Background
Amniocentesis is the most common sampling method in prenatal diagnosisAnd is generally suitable for prenatal diagnosis of mid-term pregnancy. The method is characterized in that a disposable prenatal diagnosis puncture needle penetrates through the abdominal wall and the uterine wall of a pregnant woman under the guidance of ultrasound to enter an amniotic cavity, and about 30-40ml of amniotic fluid is extracted under a common condition to be used for a laboratory detection process. By extracting amniotic fluid, cell chromosome detection, gene detection or detection of some genetic metabolites, virus antigen antibodies and virus DNA in the amniotic fluid, some congenital diseases can be diagnosed and evaluated in the fetal period. Amniotic fluid exists in the amniotic cavity, and fertilized eggs form the amniotic cavity on the seventh day of fertilization, and amniotic fluid in the early stage of pregnancyProduced primarily from amnionThe amniotic fluid from 16 weeks of gestation is mainly derived from the urine of the fetus. The amniotic fluid volume is 50 ml at 12 weeks of gestation, 400 ml at 20 weeks and 1000-1500 ml at 36-38 weeks, and the amniotic fluid volume is slightly reduced near the expected date of delivery.
The optimal time for carrying out the amniotic fluid puncture is 16-22 weeks, and according to the management method of prenatal diagnosis and technology, the indications of the amniotic fluid puncture are as follows: an advanced pregnant woman over 1.35 years old; 2. high risk population after prenatal screening; 3. pregnant women who have born children with chromosomal disorders; 4. prenatal examination of pregnant women suspected of having a chromosomal disorder; 5. the couple is a carrier of abnormal chromosome; 6. the pregnant woman may be a carrier of a certain X-linked genetic disease gene; others, such as those who have had a history of poor pregnancy or a history of exposure to specific teratogenic factors.
At present, when a doctor clinically extracts amniotic fluid of a pregnant woman, the doctor firstly punctures a puncture needle into an amniotic cavity, then manually extracts the amniotic fluid in the amniotic cavity of the pregnant woman by using a 10mL syringe, holds a needle cylinder of the syringe by one hand during extraction, and pulls a piston core rod of the syringe outwards by the other hand, so that the amniotic fluid extraction action is completed. The doctor manually operates the injector, which is hard and inconvenient for the doctor to stably operate; quantitative extraction cannot be carried out; when the fetus is close to the puncture needle, the amniotic fluid can not be timely stopped to be extracted: when the injector connected with the puncture needle is repeatedly replaced, the puncture needle possibly exits from the uterine cavity, and needs to be punctured into the uterine cavity again, so that the risks of operation complications such as postoperative abortion, amniotic fluid leakage, placenta injury, fetus injury and the like are increased.
