Medicament mixing device and use method thereof

Abstract

The invention provides a medicament mixing device and a use method thereof. The device is used for putting medicaments to be transferred or mixed into a sample part, the medicaments enter a quantification part from the sample part through the rotating direction, the rotating speed and the rotating time of the base under the effect of centrifugal force, quantification is conducted on the needed medicament, the rotating direction, the rotating speed and the rotating time of the base are adjusted again, the quantitative medicaments are controlled to enter a mixing part from the quantification part through a siphon micro valve, and therefore the needed medicaments are sufficiently and evenly mixed, the evenly-mixed medicaments are discharged from an outlet pipeline, and the PCR reaction pretreatment process including medicament injection, mixing, nucleic acid extraction and PCR reaction system establishing is achieved. According to the medicament mixing device, due to the arrangement of a channel and the siphon micro valve and adjustment on the rotating direction, the rotating speed and the rotating time of the base, control over mixing of the medicaments is simplified, and the reliability is improved; and due to the arrangement of the channel and the siphon micro valve, the medicament mixing device is simple in structure, the requirement for preparing and assembling technologies is lowered, and therefore the preparing and detecting cost is reduced.

Description

technical field [0001] The invention relates to the technical field of reagent processing devices, in particular to a drug mixing device and a method for using the same. Background technique [0002] PCR (Polymerase Chain Reaction, Polymerase Chain Reaction) is a technique for amplifying and amplifying specific DNA (deoxyribonucleic acid, deoxyribonucleic acid) fragments in vitro. When PCR amplifies DNA, it generally needs to go through three steps: high-temperature melting reaction, annealing reaction and extension reaction. After the above three steps, the number of initial DNA molecules doubles, which is a cycle at this time; the doubled DNA molecules then become The template for the next cycle, so that the cycle is multiplied, and after 30-40 cycles, the number of DNA molecules will be amplified to nearly 109 times the initial value. Thus, for the purpose of analysis and inspection, PCR can specifically amplify the DNA molecule as an analyte on a large scale. Therefore,...
