Sample analyzer

Abstract

The invention provides a sample analyzer. The sample analyzerincludes a sample device for bearing a sample, a reagent device for bearing a reagent, a sample adding device for sucking the sample and separately injecting the sample into a reaction cup, a reagent separate injection device for sucking the reagent and separately injecting the reagent into the reaction cup, an incubation device for incubating the reaction cup, a detection device for detection, a cup throwing device for throwing out the reaction cup, and a controller. The controller is electrically connected with the sample device, the reagent device, the sample adding device, the reagent separate injection device, the incubation device, the detection device and the cup throwing device, and is configured to be used for controlling the test completion duration of each test item to be the same, wherein each test item comprises a single-reagent test item and a multi-reagent test item. According to the sample analyzer, the effect of constant-speed detection on different test items is achieved, optimal configuration of resources in the sample analyzer is facilitated, and therefore the test flux of the sample analyzer during detection on the different test items is improved.

Description

technical field [0001] The present application relates to the field of in vitro analysis, and in particular, to a sample analyzer. Background technique [0002] The test process of the sample analyzer usually includes the steps of adding the sample, incubating, triggering the coagulation reaction, and detecting. However, for different test items, the completion time of the test may be different due to different incubation times, or different types or quantities of reagents required. For example, some test items only need to add trigger reagents before detection, which is called single-reagent test items; other test items need to add mixed reagents and trigger reagents before detection, which is called multi-reagent test items. [0003] For a patient's sample, a combination of multiple coagulation test items (such as four coagulation tests and two fibrinolysis tests) is usually performed, and the completion times of these tests are usually inconsistent. Further, even for th...

Problems solved by technology

[0004] Due to the configuration limitations of resources in the sample analyzer for adding samples, incubating, loading reagents, and testing, it is easy to cause conflicts in resource allocation when testing test items with different detection durations at the same time, resulting in the operation of multiple subsequent test items. Lag, which affects the accuracy of the test process and results

The test throughput of sample analyzers currently on the market is usually only counted for a single test item, but there is a big difference between this statistical scenario and the actual usage scenario of sample analyzers
