Liquid drop type biological detection device and method

Abstract

The invention discloses a liquid drop type biological detection device and method. The liquid drop type biological detection device comprises a detection base, a fixed bracket, a needle cylinder frame, a testing liquid needle cylinder, a washing liquid needle cylinder, a driving mechanism and a reactor, wherein the fixed bracket is fixedly mounted on the upper surface of the detection base; the needle cylinder frame is arranged on the fixed bracket and can horizontally step forward and move along the fixed bracket; one or more testing liquid needle cylinders are arranged; the testing liquid needle cylinder and the washing liquid needle cylinder are fixed on the needle cylinder frame and are vertically downward arranged; the driving mechanism is mounted on the fixed bracket; the reactor isfixed on the detection base; a push rod of the driving mechanism is located just above the reactor; the needle cylinder frame horizontally steps forward and moves on the fixed bracket, so that when the push rod, the needed testing liquid needle cylinder and the reactor are located on one vertical line, the push rod pushes the needed testing liquid needle cylinder, so that liquid in the testing liquid needle cylinder vertically drops into the reactor. By adopting the liquid drop type biological detection device disclosed by the invention, the consumption amount of testing liquid is greatly reduced, the detection effiency is improved, and the liquid drop type biological detection device has a good application prospect.

Description

technical field [0001] The invention relates to the technical field of biological detection instruments, in particular to a droplet type biological detection device and method. Background technique [0002] At present, the gene sequencing instruments (or other similar biological detection equipment) on the market adopt the design of continuous liquid supply and flushing, and continuously send the base reagents required for gene sequencing into the reaction chip. However, since the gene extension reaction takes time, during this period of reaction time, continuous liquid delivery requires the consumption of a large amount of reagents, resulting in high cost of reagents and a large increase in cost. Secondly, the way of continuous liquid supply will also cause mixing interference between two adjacent liquids. How to overcome the above problems is an urgent problem to be solved at present. Contents of the invention [0003] The purpose of the present invention is to overcom...
