Abstract

Disclosed are an automated card withdrawal mechanism and a single-channel fluorescent immunoassay instrument. The automated card withdrawal mechanism comprises a base plate (10), a slide rail (20), a sliding mechanism (30), a position blocking mechanism (40) and a card pushing mechanism (50), wherein the base plate (10) is provided with a long strip-shaped hollowed part (11), a card withdrawal slideway (12) is fixed under the base plate (10), a first end of the card withdrawal slideway (12) is provided with a slideway entrance enabling a test card (70) to go in and out; the slide rail (20) is mounted on the base plate (10) and is close to the hollowed part (11); the sliding mechanism (30) is movably mounted on the slide rail (20) and can move in the direction of the slide rail (20), and the test card (70) can be placed on the sliding mechanism (30); the position blocking mechanism (40) is fixed on the base plate (10) and at a position near a second end of the card withdrawal slideway (12); and the card pushing mechanism (50) is mounted on the sliding mechanism (30) and partially extends into the card withdrawal slideway (12), and can push the test card (70) out of the slideway entrance of the card withdrawal slideway (12), realising automated card withdrawal. The mechanism can realise active card pushing with reduced card withdrawal failure and high stability, and testing efficiency can be improved.

Description

technical field

[0001] The invention relates to a single-channel fluorescence immunoassay analyzer, in particular to an automatic card return mechanism and a single-channel fluorescence immunity analyzer. Background technique

[0002] The automatic card withdrawal method of the existing single-channel fluorescence immunoassay analyzer test card relies on the gravity of the test card itself to passively force the test card to slide out of the machine. On the one hand, this passive card ejection method will not be able to eject the card smoothly due to the uncertain location of the card drop, resulting in the instrument being stuck internally. On the other hand, when the test cards are piled up outside the instrument, the instrument will also be stuck.

[0003] In view of this, it is necessary to propose a further improvement on the ejection structure of the current single-channel fluorescence immunoassay analyzer. Contents of the invention

[0004] In order to solve at lea...
