A genetic detection verification extraction system that can be applied in teaching and a genetic screening method for rare diseases

Abstract

The invention discloses a gene detection verification extraction system applicable in teaching and a gene screening method for rare diseases, including a puncture and drainage mechanism, a blood collection mechanism and a supernatant fluid collection mechanism, and the puncture and drainage mechanism includes a first puncture needle and the second puncture needle, the first puncture needle and the second puncture needle are connected through a first connecting hose, and a flow blocking mechanism is sleeved on the first connecting hose, and the flow blocking mechanism It includes an upper cover and a lower cover, one end of the upper cover and the lower cover is connected by a movable shaft, and a first limiting groove is provided on one side of the upper cover, and the cross section of the first limiting groove is a curved arc , the lower cover is fixed with a limit column, the limit column is adapted to the first limit groove, and the limit post is in contact with the upper cover through a limit nut. The beneficial effects of the present invention are: the distance between the E-shaped baffle plate and the vertical baffle plate can be accurately controlled, so that the speed of liquid discharge can be accurately controlled, and the comfort of relevant personnel can be ensured.

Description

technical field [0001] The invention relates to the technical field of genetic examination, in particular to a genetic examination verification extraction system applicable in teaching and a genetic screening method for rare diseases. Background technique [0002] Down syndrome (trisomy 21 syndrome), also known as congenital stupidity or Down syndrome, is the earliest identified chromosomal disease. 60% of the children died early in the fetus and miscarried, and the survivors had obvious symptoms. Mental retardation, special face, growth and development disorders and multiple deformities. Down syndrome (trisomy 21 syndrome), also known as congenital stupidity or Down syndrome, is the earliest identified chromosomal disease. 60% of the children died early in the fetus and miscarried, and the survivors had obvious intelligence. Backward, special face, growth and development disorders and multiple deformities. [0003] For pregnant women, they are emotionally unstable when th...

Problems solved by technology

[0003] For pregnant women, they are emotionally unstable when they need it. When drawing blood, the puncture tube on the existing negative pressure bottle pierces the corresponding part, and then the flow regulator of the disposable infusion tube is opened to allow the blood to enter through the hose. into the negative pressure bottle, but the existing disposable infusion tube flow regulator controls the pressure in the negative pressure bottle by squeezing the hose through friction. The flow regulator cannot accurately control the flow and ensure that the air pressure in the negative pressure bottle will not leak
