[0016] Beneficial effects:

[0017] 1. By setting up a negative pressure tube and a shunt tube, during collection, the negative pressure machine sucks the air in the negative pressure tube through the connecting main tube and the connecting branch tube, so that negative pressure is generated in the negative pressure tube. The negative pressure draws the amniotic fluid into the negative pressure tube through the collection tube. At this time, because the negative pressure in the negative pressure tube is greater than the weight of the amniotic fluid, the amniotic fluid will not flow out through the shunt tube. When the collection is completed, the negative pressure machine stops working, the negative pressure in the negative pressure tube disappears, and the amniotic fluid flows out of the test tube through the shunt tube by its own weight, realizing the automatic completion of collection and liquid separation, and the amniotic fluid will not come into contact with the outside air throughout the process. While ensuring hygiene and safety, the workload of medical staff is reduced.

[0018] 2. By setting up a closed cover and a sterilization lamp, the collection component can be completely enclosed by the closed cover to prevent air from circulating inside and outside. The enclosed air can then be sterilized by the sterilization lamp, so that the collection component is in a sterile environment, reducing the risk of pathogens adhering to the outside of the collection component and further improving the requirements for hygiene and safety.
