Fluid control device of gene sequencing

Abstract

The invention discloses a fluid control device of gene sequencing. The fluid control device of gene sequencing comprises a reagent assembly, a first multiported valve, a first three-port valve, a gene sequencing chip and a drive assembly; the reagent assembly is connected with the gene sequencing chip through the first multiported valve and the three-port valve; due to the fact that a first gene sequencing passage and a second gene sequencing passage are arranged in the gene sequencing chip, reagents in the reagent assembly can automatically flow into the first gene sequencing passage and the second gene sequencing passage to conduct reaction and fluorescence image acquisition, when fluorescent sequencing reaction is conducted in the first gene sequencing passage, fluorescence image acquisition can be conducted in the second gene sequencing passage, and the gene sequencing time can be effectively reduced, that is to say, the gene sequencing efficiency is effectively increased. For the fluid control device of gene sequencing, the gene sequencing cost is reduced, and the gene sequencing efficiency is increased.
