Description

Technical Field

[0002] A fully automated biochemical and immunoassay analyzer is a device that performs biochemical and immunological tests simultaneously with a single sample injection. A fully automated biochemical and immunoassay analyzer generally includes a mounting base and a scanning component. The mounting base is used to install reagent cards, which have barcodes. The scanning component photographs the barcodes to obtain the barcode information from the reagent card, enabling the analyzer to perform corresponding control based on the barcode information.

[0003] For example, Chinese patent application CN120233108A discloses a sample testing device for point-of-care testing, including a first loading seat, a second loading seat, and a scanning component. The first loading seat carries a reagent kit containing a sample to be tested. The second loading seat carries a reagent card, which includes a scanning area. The scanning component scans the scanning area of ​​the reagent card to obtain its barcode information. This barcode information can be used to indicate the qualification information of the reagent card, relevant information about the sample to be tested, etc., enabling the sample testing device to perform corresponding control based on the barcode information. Therefore, the performance of the scanning component is crucial for sample testing; however, existing technologies lack testing devices for scanning components.
