Gene detection, verification and extraction system applicable to teaching and gene screening method for rare diseases

Abstract

The invention discloses a gene detection, verification and extraction system applicable to teaching and a gene screening method for rare diseases. The system comprises a puncture drainage mechanism, ablood collection mechanism and an upper layer liquid collection mechanism, wherein the puncture drainage mechanism comprises a first puncture needle and a second puncture needle, the first puncture needle and the second puncture needle are connected through a first connecting hose, a flow blocking mechanism is arranged on the first connecting hose in a sleeving manner, the flow blocking mechanismcomprises an upper cover and a lower cover, the upper cover is connected with one end of the lower cover through a movable shaft, a first limiting groove is formed in one side of the upper cover, thecross section of the first limiting groove is a major arc, a limiting column is fixedly arranged on the lower cover, the limiting column is matched with the first limiting groove, and the limiting column is in contact with the upper cover through a limiting nut. The beneficial effects of the gene detection, verification and extraction system applicable to teaching and the gene screening method for rare diseases are as follows: the distance between a E-shaped baffle plate and a vertical baffle plate can be accurately controlled, so that the liquid outlet speed is accurately controlled, and thecomfort of related personnel is 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
