Method and device for treating and storing substances such as protein in biological fluid

Abstract

The invention relates to a method and a device for treating and storing substances such as protein in biological fluid, a multifunctional post-treatment device and a membrane adapter membrane lifting device are arranged along one side edge of a workbench, a filter screen rack recovery table is arranged on the membrane adapter membrane lifting device, a mechanical arm is arranged on the workbench, and the mechanical arm is connected with the membrane adapter membrane lifting device. The mechanical arm can horizontally move on an X axis and a Y axis, a mechanical claw is arranged on the mechanical arm, a pipette and a grabber are arranged at the front end of the mechanical claw, a sample frame is arranged in the middle of the workbench, a scanning device and a suction filtration system are arranged on one side of the sample frame, and a suction filtration device is arranged on the other side of the sample frame. The suction filtration system is used for allowing sample body fluid in a sample test tube to flow into the membrane adapter through rotation, the suction filtration system corresponds to the rotary workbench in position, and a feeding and discharging station, a suction filtration station, a first drying station and a second drying station are sequentially arranged on the upper circumference of the rotary workbench. Meanwhile, multiple steps are operated at the same time, the working efficiency is improved, and the problem of cross contamination is solved.

Description

technical field [0001] The present invention relates to a method and device for processing and preserving proteins and other substances in biological fluids, wherein the biological fluids specifically include urine, saliva, human milk, blood and other liquids. Background technique [0002] Biological specimens are of great value for medical research and medical practice. Biological fluids tend to contain a wealth of information about the patient, with proteins thought to contain potential markers of kidney disease that are thought to encompass the entire body. Biological fluids are important biological samples, if they can be preserved together with clinical medical records at each stage of the disease, then in the future retrospective and prospective studies to find biomarkers, especially in large-scale clinical validation experiments , will play an immeasurable role. However, biological samples in current medical practice are not fully preserved. This is because the pre...
