Nucleic acid molecular hybridization instrument

Abstract

The invention relates to the technical field of medical instruments, and discloses a nucleic acid molecule hybridization instrument. The nucleic acid molecule hybridization instrument comprises an enclosure, a reaction platform, liquid injection needles, liquid injection pumps, liquid storage tanks, temperature sensors, a temperature adjustment device and a controller, wherein the reaction platform and the liquid injection needles are arranged in the enclosure in a relatively moving manner; the liquid injection pumps are connected with the liquid injection needles and the liquid storage tanks; first electric control valves are arranged on pipelines for connecting the liquid injection pumps with the liquid injection needles; second electric control valves are arranged on pipelines between the liquid injection pumps and the liquid storage tanks; the temperature sensors are located in the liquid storage tanks; the temperature adjustment device is used for heating or cooling the liquid storage tanks; the controller is connected with the temperature adjustment device, the temperature sensors and the liquid injection pumps. The controller of the nucleic acid molecule hybridization instrument controls the temperature adjustment device to adjust the temperature of liquid in the liquid storage tanks and receives the liquid temperature, detected by the sensors, in the liquid storage tanks; when the liquid temperature reaches a preset value, the controller controls the liquid injection pumps to convey the liquid of the liquid storage tanks to the reaction platform through the liquid injection needles, so that a full-automatic pretreatment process is realized.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a nucleic acid molecular hybridization instrument. Background technique [0002] With the increasing demand for robots and automated processing in the development of modern industry, all walks of life, especially chemical and biological industries, have higher and higher requirements for test automation. [0003] Nucleic acid molecular hybridization technology refers to the process in which two nucleic acid single strands (DNA or RNA) with certain homologous sequences undergo annealing treatment according to the principle of complementary base pairing under certain conditions to form heterogeneous double strands. At present, most of the existing nucleic acid molecular hybridization instruments are semi-automatic hybridization instruments with manual operation and machine control, and the operation is cumbersome. Some automatic hybridization instruments also have the foll...
