Description

Technical Field

[0001] The utility model belongs to the technical field of microplate sample addition, and in particular relates to an immunoassay microplate sample addition auxiliary device. Background Art

[0002] An immunoassay microplate is an instrument used for immunoassays and immunoassays. The detection principle of the microplate is to detect the presence and concentration of a target substance through fluorescence, luminescence, absorbance, etc. based on a specific chemical reaction or biological reaction. In the detection process, in order to facilitate the addition of samples to the wells, an immunoassay microplate sample addition auxiliary device is used, such as "an immunoassay microplate sample addition auxiliary device, including an auxiliary sample addition box, a flip cover, an adsorption control sample mechanism, an auxiliary ejection mechanism, and a sample addition tube" disclosed in the existing patent with publication number CN117030999A. It can be seen that the application describes a common immunoassay microplate sample addition auxiliary device, which can slide multiple sample addition tubes onto the microplate through a sliding rack and realize the operation of adding samples to the wells;

[0003] However, when the immunoassay microplate loading auxiliary device in the prior art is actually used, after the slide with multiple loading tubes slides to the top of the microplate, since the top plate on the slide cannot be pressed down, the operator needs to manually remove the loading tubes and insert them into the microplate for loading. This is not easy to operate and reduces the overall work efficiency. For this reason, the utility model proposes an immunoassay microplate loading auxiliary device. Utility Model Content

[0004] The utility model aims to provide an auxiliary device for adding samples to a microplate of an immunoassay to solve the problems raised in the above-mentioned background technology.

[0006] Preferably, the bottom end of the spring is fixed to the bottom inner wall of the inner groove.

[0007] Preferably, a top column is fixed to the top surface of the telescopic support column, and the top end of the top column passes through the top of the top plate. Both end surfaces of the top plate are provided with through holes, and the through holes correspond to the top columns. L-shaped rubber pads are fixed to the top of both ends of the top plate, and the L-shaped rubber pads are fitted with the top end of the top column. An integrated side clamp block is provided on one side surface of the L-shaped rubber pad, and a side clamp groove corresponding to the side clamp block is provided on the side of the top column, and the side clamp block is embedded in the side clamp groove.

[0008] Preferably, a plurality of sample addition wells are provided on the top surface of the immunoassay microplate, and the positions of the sample addition tubes correspond to the sample addition wells.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model improves and optimizes the immunoassay microplate sample loading auxiliary device in the prior art, and sets the top plate above two retractable support columns that can be raised and lowered, so that after the subsequent top plate is pushed to the top of the immunoassay microplate, it can be directly moved down with all the sample tubes to complete the loading. After loading the samples, it only needs to loosen the top plate to move the top plate up and reset with the sample tubes. The overall operation is very simple and quick, which improves the work efficiency during detection. BRIEF DESCRIPTION OF THE DRAWINGS

In actual use, the top plate 4 can be pulled toward the immunoassay microplate 3, so that the telescopic support column 6 slides with the T-shaped slide seat 5 in the T-shaped slide groove 21. When the sample tube 7 is in a suitable position above the immunoassay microplate 3, it is only necessary to press the top plate 4 down with force, so that the telescopic support column 6 moves down with the inner slide block 61 and compress the spring 52, so that the top plate 4 and the telescopic support column 6 can be lowered, causing the bottom end of the sample tube 7 to be inserted into the sample hole at the top of the immunoassay microplate 3 for sample addition.
