Problems solved by technology

[0004] At present, the existing flow fluorescence detectors on the market are not very stable in structure, resulting in unstable optical detection, and the detection results are not accurate enough; in addition, the existing mechanisms for sucking samples are not perfect enough, and there are unstable factors , the amount of sample suction is not easy to control, and it needs to be manually matched with sample addition, so it has certain limitations

Abstract

The invention relates to the technical field of medical equipment, in particular to a sample suction device and a flow fluorescence detector. The sample suction device is used for sucking a sample in a reaction cup and is characterized in that the sample suction device comprises a bottom plate, a stepping motor, a steel needle and a swab, wherein the swab is located right below the lower end of the steel needle, a needle washing passage is arranged in the vertical direction of the swab, the lower end of the steel needle stretches into the needle washing passage, the steel needle is slidingly connected with the bottom plate by a sliding mechanism, the stepping motor drives the steel needle to move up and down, and the steel needle is connected with the sliding mechanism by a switching block. The invention provides the sample suction device which is simple and stable in structure and full-automatic in sample adding and the flow fluorescence detector.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a sample suction device and a flow fluorescence detector. Background technique [0002] Flow fluorescence detector, with fluorescent coded microspheres as the core, is a multi-indicator parallel analysis technology platform integrating flow principle, laser analysis, high-speed digital signal processing and other technologies, which can accurately and quantitatively detect 100 different Biomolecules; with the characteristics of high throughput, high sensitivity, parallel detection, etc.; can be used in various aspects and fields of research such as immunoassay, nucleic acid research, enzymatic analysis, receptor, ligand recognition analysis, etc. [0003] The technical principle of flow cytometry is as follows: the fluorescently labeled single cell (or particle) suspension enters the aspirator, and then enters the flow chamber with the sheath fluid. The pipe before ent...
