Description

Technical Field

[0001] The utility model relates to the technical field of medical diagnosis and analysis, in particular to a reagent temporary storage device for preventing precipitation. Background Technique

[0002] In the immune reaction, a variety of biological reagents such as antigens and antibodies need to be mixed with samples, and then heated and incubated to enable the combination of antigens and antibodies. In chemiluminescence immunoassay, the magnetic particle complex formed by the combination of antigens, antibodies, and magnetic particles is a carrier of the signal to be measured; in the process of such chemiluminescence immunoassay, reagent pipetting or temporary storage of reagents is often required according to different stages or detection requirements. For example, a Chinese patent with the authorized announcement number CN220549490U discloses a reagent temporary storage component for a detector; it includes a temporary storage rack board, a temporary storage upper cover, a light-shielding pull plate, a reagent rack body, a refrigeration module, and a pull plate motor; auxiliary vertical bars are arranged on the inner wall of the temporary storage rack board; the temporary storage upper cover is covered and fixed above the auxiliary vertical bars; the reagent rack body is assembled below the temporary storage upper cover through the auxiliary vertical bars; the refrigeration module is arranged below the reagent rack body; one end of the light-shielding pull plate is inserted into the temporary storage upper cover, and the other end is connected to a traction spring piece; the pull plate motor is fixed on the inner wall of the temporary storage rack board, and its output end is connected to and drives the light-shielding pull plate; by adopting the utility model, the protection and shielding of the reagent tube are realized through the pullable and movable light-shielding pull plate, ensuring that the reagent is not contaminated by light sources and other impurities during the temporary storage process in the reagent tube, improving the accuracy of the overall detection or reading; and a refrigeration module is additionally configured to protect the activity of the reagent, ensuring the quality of the reagent and improving the detection efficiency and accuracy.

[0003] However, in practical applications, the above reagent temporary storage component still has the following deficiencies: Since the components of the reagent are relatively complex, some reagents contain magnetic beads / microspheres. Under the action of gravity, the magnetic beads / microspheres will precipitate at the bottom of the reagent tube, resulting in a situation where the concentration at the bottom of the reagent tube is higher than that in the middle of the reagent tube, affecting the accuracy of the detection result after the extraction head of the detector extracts. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a reagent temporary storage device for preventing precipitation in view of the above deficiencies, which can effectively prevent the magnetic beads / microspheres in the reagent from precipitating at the bottom of the reagent tube, making the concentration at the bottom of the reagent tube the same as that in the middle of the reagent tube, and ensuring the accuracy of the detection result after the extraction head of the detector extracts.

A rotating position and a plurality of fixed positions are arranged on the temporary storage rack, and both the rotating position and the fixed positions are used for inserting reagent tubes. The driving mechanism drives the reagent tube on the rotating position to rotate through the transmission structure.

[0007] Further, a connecting ring is coaxially connected to the bottom of the reagent tube, and a plurality of convex strips connecting the reagent tube are radially arranged on the connecting ring; the transmission structure includes a plurality of driven gears rotatably connected to the bottom of the temporary storage box, adjacent driven gears are meshed with each other, a cylindrical connecting seat is arranged on the driven gear, and an insertion hole is arranged on the connecting seat opposite to the connecting ring.

[0010] Further, one side of the temporary storage rack is an arc surface, the other side of the temporary storage rack is a plane, and the arc surface is arranged close to the rotating position.

[0011] The beneficial effects of the present utility model are:
