Abstract

The invention relates to an automatic precision loading device of immunoassay technology. The automatic precision loading device comprises a stepping motor, a screw, a motor clamping plate, a motor front plate, an optical axis guide rail, an injection sliding block, a motor baffle plate, an injector, an optical coupling sensor, an optical coupling sheet and a three-way block, and is characterized in that: the stepping motor and a precision screw kinematic pair are taken as transmission components; the injection sliding block is connected with a piston of the injector and performs back-and-forth linear motion along the optical axis guide rail; and a trigger point of the optical coupling sensor is taken as a completion point of injection action and an initial point of a next action cycle. The design ensures the precision of the device, and particularly reliably ensures repeated precision; and the automatic precision loading device has a simple structure, is convenient to maintain and can realize full automatic quantitative loading of an instrument. The loading device is widely suitable for loading mechanisms such as luminescence detection analyzers, biochemical analyzers, electrolytic analyzers and the like which need quantitative loading instruments.

Description

technical field [0001] The invention relates to an automatic sample-loading structural device used for quantitative sample-loading of samples, reagents, substrates, etc. in a full-automatic immunoassay system. Background technique [0002] Immunoassay is a means of biomedical detection using the specific reaction of antigen and antibody. It uses isotopes, enzymes, chemiluminescent substances, etc. to amplify and display the signal of the test sample. Therefore, it is often used in secretion, infectious diseases, immunity, Tumor, pharmacology and other biomedical sample detection. The detection accuracy of immunoassay equipment depends to a certain extent on the accuracy of quantitative sampling. Only by ensuring the accuracy of samples, reagents and substrates, can the accuracy of detection data and results be guaranteed. This is the accuracy of immunoassay equipment. Foundation. In the semi-automatic immunoassay system, the addition of samples, reagents and substrates is ...
