Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically to a reagent card incubator. Background Technology

[0002] A dry fluorescence immunoassay analyzer is an instrument used for quantitative or qualitative analysis, typically for detecting specific substances in human serum or plasma. An incubator, which heats and maintains a constant temperature for a reagent card containing a mixture of reagents and samples, is an essential component of this instrument.

[0003] The existing technology, disclosed in CN205607844U, is titled "A Reagent Card Incubation Structure." Based on existing technology, it uses a reagent card clamping plate to secure the reagent card inserted into the incubator, preventing it from shifting after insertion and ensuring it doesn't easily fall out, thus guaranteeing uniform heating of the reagent. However, this incubator requires multiple reagent card clamping plates, making assembly cumbersome and reducing efficiency. Furthermore, it cannot display the real-time temperature status of the reagent card, making it inconvenient to use.

[0004] Therefore, how to provide a reagent card incubator that can fix reagent cards without assembling multiple reagent card presses, improve assembly convenience, and allow operators to monitor the incubation status of reagent cards in real time, thereby improving ease of use, is a problem that urgently needs to be solved by those skilled in the art.
