Description
Technical Field
The utility model belongs to the field of medical instruments, and particularly relates to a sterile amniotic fluid specimen kit integrating rapid collection and accommodation.
Background
China is one of the high-incidence countries of birth defects, according to survey, about 90 ten thousand new cases occur in China every year, more than 60 ten thousand Down syndrome and Edward syndrome sick children are the most common chromosome genetic diseases, the clinical manifestations are serious congenital intelligence disorder, special face and the like, and an effective treatment method is still lacking clinically at present. Therefore, how to take effective measures to prevent and screen down syndrome and edward syndrome in clinic becomes the key point of the current research.
Amniotic fluid puncture is a common prenatal screening method and is suitable for prenatal diagnosis of mid-term pregnancy. The domestic research shows that the amniotic fluid puncture is a novel screening method, the fetus is not easy to be punctured, the uterine cavity is not suddenly changed, the success rate of cell culture is high, the operations of flaking, dyeing and the like can be finished, and the diagnosis and screening of the chromosome karyotype and the chromosome genetic disease of the fetus can be judged. Meanwhile, amniotic fluid puncture can also complete amniotic fluid cell DNA screening, and diagnosis of a genetic disease and a metabolic disease is realized. Most pregnant women can terminate the pregnancy in time when the fetus with the problems found by amniotic fluid puncture examination in the gestational period, which is helpful for improving the quality of the population in China.
The traditional amniotic fluid puncture collection method has some defects in the clinical practice process, and the defects cause that the traditional amniotic fluid puncture collection method cannot meet the requirements of accurate and high-standard use in the current medical field, and the defects of the traditional amniotic fluid puncture collection method are specifically described as follows:
firstly, after the amniotic fluid puncture is successful, 2mL of amniotic fluid is extracted by using 5mL of empty needles, then 10mL of amniotic fluid is respectively extracted by using 2 empty needles with 10mL, and the firstly extracted 2mL of amniotic fluid is discarded because substances such as blood and the like possibly are doped in a small amount and the purity is insufficient, so that the success rate of cell culture is influenced. 2 later-extracted 10mL amniotic fluids, the obstetrician injects the empty needle filled with the amniotic fluids into 2 amniotic fluid collecting pipes respectively, the process needs another medical personnel to unscrew the tube cover of the amniotic fluid collecting pipe by hand, and after all the amniotic fluids are injected into the collecting pipe, the tube cover is screwed down to seal the amniotic fluid specimen, and then the amniotic fluids are used for detection.
The method obviously wastes time and labor, and the process of injecting the amniotic fluid into the amniotic fluid collecting pipe and the process of unscrewing or screwing the pipe cover of the amniotic fluid collecting pipe can pollute the inner pipe mouth of the amniotic fluid collecting pipe, thereby influencing the effective operation of later-stage inspection work.
(II) traditional amniotic fluid puncture collection method, the replacement process between the amniotic fluid inside the hollow needle and the amniotic fluid collecting pipe increases the exposure time of the amniotic fluid air, so that the amniotic fluid inside the amniotic fluid collecting pipe is inevitably contacted with the outside air, dust, bacteria and particles in the air can influence the purity of the amniotic fluid, serious people can cause amniotic fluid pollution, and the subsequent inspection work of the amniotic fluid cannot be guaranteed to be smoothly performed by the operation method.
Therefore, it is an urgent need in the art to design a new amniotic fluid collecting device to solve the above problems.
