Abstract

The invention belongs to the technical field of automatic treatment of biological samples, and discloses a blood layering identification method and device for a blood dividing workstation. The device comprises a test tube rack loading and conveying platform with a rectangular circulating channel, wherein an uncovering station and a detection station are sequentially arranged in the middle of a feeding channel; the automatic cover opening mechanism is used for performing accurate cover opening or closing operation on the sample tube; the light supplementing unit comprises a white light source and a blue light source which can be independently switched and is used for providing vertically downward multispectral supplementary light; the camera shooting unit is located on the side of the detection station. The identification method comprises the following steps: after uncovering, transferring the tube body back to the test tube rack for detection, and circularly processing the logic of a plurality of sample tubes on the same test tube rack. Reflection interference is eliminated through top multi-color vertical light supplement, and the recognition accuracy of the blood leukocyte layer interface is remarkably improved; and meanwhile, the rectangular circulating platform realizes a high-throughput and full-automatic sample treatment process in a compact space.
