Cleaning and liquid changing mechanism, chip detection apparatus, and control method of chip detection apparatus

Abstract

The invention provides a cleaning and liquid changing mechanism, a chip detection apparatus, and a control method of the chip detection apparatus. The chip detection apparatus comprises a delivery mechanism, the cleaning and liquid changing mechanism and a test reaction device, the delivery mechanism is used for conveying a test chip, the cleaning and liquid changing mechanism is used for charging a test liquid to the test chip on the conveying mechanism or sucking the test liquid from the test chip, and the delivery mechanism traverses through the test reaction device. The automatic movement of the test chip is realized, and the heat insulation and moisture retention functions of the test reaction device are used to make the delivery mechanism pass through the test reaction device at a preset speed in a preset time, and the cleaning and liquid changing mechanism is used to charge the test liquid to the test chip and suck the test liquid from the test chip. The cleaning and liquid changing mechanism is used to realize multi-angle liquid charging, liquid sucking and air blowing cleaning in order to realize highly-efficient and accurate detection of the biological chip.

Description

technical field [0001] The invention relates to the field of chip detection, in particular to a cleaning and liquid changing mechanism, a chip detection device and a control method for the chip detection device. Background technique [0002] Biochip technology is a miniature biochemical analysis system that integrates the discontinuous analysis process in the field of life sciences on the surface of a silicon chip or glass chip through microtechnology and according to the principle of specific interaction between molecules, so as to realize the analysis of cells, proteins, etc. Accurate, rapid and informative detection of genes, genes and other biological components. According to the different biological materials solidified on the chip, biochips can be divided into gene chips, protein chips, polysaccharide chips and neuron chips.

Problems solved by technology

[0003] When dealing with biochips, inspectors need to go through a series of operations: first add the substance to be detected, then add the hybridization solution, then react at the preset temperature, and then need a series of reaction reagents to react, and finally The surface is cleaned by a centrifuge or blowing air, and then can be observed and analyzed by a CCD camera. It can be seen that the equipment involved in the process includes heat preservation equipment, manual sampler, centrifugal equipment, cleaning equipment, air gun and other devices. , the process is highly complex, the efficiency of manual operation is low, and the procedures are cumbersome, and then human errors are prone to occur, which makes the detection fail
