Intestinal flora nucleic acid extraction system

Abstract

The invention discloses an intestinal flora nucleic acid extraction system, and belongs to the technical field of medical clinical examination. The system can mainly solve problems that existing traditional methods are time-consuming and labor-consuming and low in working efficiency and experiment results and quality cannot be guaranteed. The main characteristics of the system are that the systemincludes a specimen sample introduction module, an intelligent centrifugation module, a test tube sample introduction module, a mechanical arm module and a reagent sample introduction module; the intelligent centrifugation module is located in the middle of a machine base plate; the specimen sample introduction module and the reagent sample introduction module are arranged on the middle layer frame of a machine frame and located at the upper side part of the intelligent centrifugation module; the reagent sample introduction module is movably arranged on the middle layer frame of the machine frame and located above the intelligent centrifugation module; and the mechanical arm module is arranged on the upper layer frame of the machine frame. The system is mainly used for automatically extracting bacterial nucleic acid in manure.

Description

technical field [0001] The invention belongs to the technical field of medical and health clinical testing, in particular to automatic testing instruments, which are mainly used for the extraction of intestinal flora nucleic acid of stool samples and automated instruments for flora analysis, and can be expanded to other biological samples, such as whole blood, plasma, and throat swabs , tissue, sputum, cerebrospinal fluid and other biological samples of nucleic acid extraction. Background technique [0002] With the continuous development of modern biological technology, the research results of biological science have been widely used. Nucleic acid is a biological macromolecular compound synthesized by many nucleotides. Carriers are widely present in all animal and plant cells and microorganisms, play an important role in the life process of organisms, and play an irreplaceable role in the field of life research. Nucleic acid extraction and purification are particularly imp...
