Low temperature preservation device of test sample for biological gene detection

Abstract

The invention discloses a low temperature preservation device of a test sample for biological gene detection. The low temperature preservation device comprises a refrigeration box body, a test samplebox body and a test sample block, universal wheels are installed on both ends of a bottom end of the refrigeration box body, a refrigeration pipe penetrating through the refrigeration box body is installed on an output end of an air compressor, one end of the refrigeration pipe away from the air compressor penetrates through a top end of the test sample box body, a third slide rail is horizontallyinstalled at the bottom end in the test sample box body, a hydraulic cylinder is vertically installed at the middle position of the top end of a second slide block, sleeves are uniformly and vertically installed at the top ends of the second slide block on the both sides of the hydraulic cylinder, a metal rod penetrating through the top ends of the sleeve is vertically installed at the top end ofa second spring, a first spring connected with the test sample block is vertically installed at the top end of the sleeve on the outer side of the metal rod, and fourth springs are uniformly and vertically installed at the bottom end in a test sample bin. According to the low temperature preservation device of the test sample for biological gene detection, when the temperature is too high, the air compressor starts to cool to facilitate the low temperature preservation of the test sample.

Description

technical field [0001] The invention relates to the technical field of biological gene detection, in particular to a low-temperature storage device for samples used in biological gene detection. Background technique [0002] Gene is the basic unit of heredity, a DNA or RNA sequence that carries genetic information. It transmits the genetic information to the next generation through replication, and guides the synthesis of proteins to express the genetic information it carries, thereby controlling the expression of the traits of individual organisms. Genetic testing is The technique of detecting DNA through blood, other body fluids, or cells is to take the peripheral venous blood or other tissue cells of the subject, amplify their genetic information, and then use specific equipment to detect the DNA molecular information in the cells of the subject. It is a method to analyze the gene types and gene defects contained in it and whether its expression function is normal, so tha...

Problems solved by technology

[0003] However, most of the cryopreservation devices for biological gene detection samples on the market are not convenient for detecting and controlling the temperature inside the device, and the cryopreservation devices for biological gene detection samples cannot be applied to sample storage devices of different sizes
