Reaction vessel detection device

Abstract

The invention provides a reaction vessel detection device. The reaction vessel detection device comprises a reaction vessel loading module, a reaction vessel conveying module, an optical detection module and a control module, wherein the reaction vessel loading module is used for placing reaction vessels on the reaction vessel conveying module one by one; the reaction vessel conveying module is used for conveying the reaction vessels to a first detection station and an unqualified product removing station one by one; the optical detection module comprises a light source component used for irradiating light to the reaction vessels at the first detection station and an optical detection component used for obtaining transmission light signals; the control module is used for calculating at least two transmission light signals to obtain characteristic parameters, comparing the characteristic parameters with preset parameters, judging whether the reaction vessels are qualified or not according to comparison results and controlling a reaction vessel removing mechanism to remove unqualified reaction vessels which are conveyed to the unqualified product removing station if the reaction vessels are unqualified. Through the reaction vessel detection device, the purpose of automatically detecting whether the reaction vessels are qualified or not can be achieved; and the reaction vessel detection device is high in detection accuracy and detection efficiency.

Description

technical field [0001] The invention relates to the field of quality detection of reaction containers used in the field of in vitro diagnosis, in particular to a detection device for reaction containers. Background technique [0002] In the in vitro diagnostic analyzer, after the sample and the reagent are added to the reaction container, the sample and the reagent in the reaction container are mixed to obtain a reaction solution for detecting the content of a certain substance in the sample. The reaction container containing the reaction liquid will be transported to the detection station, and the detector in the detection station detects the light signal emitted by the reaction liquid, or detects the light signal transmitted through the reaction container. If the quality of the reaction vessel is not up to standard, for example, the wall thickness of the reaction vessel is uneven, it will affect the accuracy of the detector for detecting the optical signal. [0003] In th...

Problems solved by technology

However, if there is some imperceptible failure of the instrument used in the upstream reaction vessel manufacturing end, or the precision control of the instrument used in the upstream reaction vessel manufacturing end is not good, the vessel wall thickness of the manufactured reaction vessel cannot be judged Whether it is uniform or other defects, so that it is impossible to judge whether the reaction vessel is qualified
