Description

Obstetrical amniotic fluid detection sampling device

Technical Field

The invention relates to the technical field of medical instruments, in particular to an obstetrical amniotic fluid detection sampling device.

Background

The liquid filled in the amniotic cavity is called amniotic fluid, the source, the amount and the components of the amniotic fluid change with different gestational weeks, in the early stage of pregnancy, the amniotic fluid is mainly dialysate which is obtained by leading maternal serum into the amniotic cavity through a placenta, a small amount of the dialysate seeps from the surface of the placenta and the surface of an umbilical cord, after the blood circulation of a fetus is formed, water and small molecules in the fetus can seep out through the skin of the fetus without keratinization to form a part of the amniotic fluid, the excretion function of the kidney of the fetus exists in 11-14 weeks of pregnancy, therefore, urine discharged by the fetus after the middle stage of pregnancy is an important source of the amniotic fluid, in the full-term pregnancy, the amount of the amniotic fluid is 800-1000 ml, the amniotic fluid is colorless and transparent alkaline liquid, more than 90 percent of the water is water, and in addition, minerals, urea, uric acid, creatinine, fetal fat, fetal epithelial cells and the like are contained, the AFP amount in the amniotic fluid can be, the fetus can be screened for genetic diseases.

Amniotic fluid examination is mostly performed in 16-20 gestation periods, amniocentesis is performed by penetrating a puncture needle into an amniocente, and then amniotic fluid is extracted for examination, so that the amniotic fluid is an important means for understanding fetal development conditions and treating fetal diseases or stopping prenatal diagnosis of pregnancy, the amniotic fluid mainly comes from leakage of fetal urine and amniotic epithelium after the middle term of pregnancy, and contains deciduous cells of fetal skin, enzymes, hormones and fetal metabolites, so that amniotic fluid components can be examined to reflect fetal conditions, and the amniotic fluid is taken for examination, and examination items include cell culture, sex chromosome identification, chromosome karyotype analysis, amniotic fluid fetal protein determination, amniotic fluid biochemical examination and the like, so as to determine the fetal maturity and health conditions and diagnose whether a fetus is normal or has some genetic diseases.

The specific operation process is that under the guidance of the ultrasonic probe, a doctor uses a slender puncture needle to penetrate through the abdominal wall, the myometrium and the amnion to enter the amniotic cavity, and extracts 20-30 ml of amniotic fluid to check the chromosome, DNA, biochemical components and the like of fetal cells in the amniotic fluid, so that the method is the most commonly used prenatal diagnosis technology; but at present the sample to amniotic fluid detection is mostly manual sampling, operates unstably, causes the influence to foetus or pregnant woman easily, and needs medical personnel to hand fixedly to the sample needle all the time, can lead to the sample process hard like this.
