Fully-automatic fluorescence immunoassay system

Abstract

The invention discloses a fully-automatic fluorescence immunoassay system comprising a suction head placing frame, a sample uniformly-shaking unit, a buffer solution feeding unit, a test paper sheet conveying unit, a three-dimensional sample adding unit, a detection unit and a signal processing control unit, wherein a suction head is placed on the suction head placing frame; the sample uniformly-shaking unit is used for uniformly shaking a to-be-detected sample; the buffer solution feeding unit is used for conveying a buffer solution plate to a working position, and the buffer solution plate is abandoned after running out; the test paper sheet conveying unit is used for pushing out test paper sheets from a test paper box and respectively conveying the test paper sheets to a sample adding position and a detection position; the three-dimensional sample adding unit is used for loading the suction head; and the detection unit is used for detecting the test paper sheets which are subjected to sample adding, and the test paper sheets are abandoned after detection ends. According to the fully-automatic fluorescence immunoassay system disclosed by the invention, the strength and error rate of detection operations can be significantly reduced by virtue of fully-automatic operations, the detection throughput can reach 60 tests per hour, and thus the requirements of large batch detection can be met; and according to the fully-automatic fluorescence immunoassay system, the suction and mixing of the samples and the sample adding of the test paper sheets are performed by using the disposable suction heads, so that the cross contamination among the samples can be avoided, and the accuracy of results can be improved.

Description

technical field [0001] The invention relates to the field of fluorescent immunoassay, in particular to an automatic fluorescent immunoassay system. Background technique [0002] C-reactive protein (CRP) is a clinically commonly used inflammatory indicator with high sensitivity and low specificity. It has been used as a routine detection item in hospitals and used as an auxiliary judgment basis in the diagnosis of many diseases. The determination of CRP will not be affected by factors such as age, gender, anemia, hyperglobulinemia, pregnancy, etc. It can be used to assist white blood cell count and erythrocyte sedimentation rate determination to distinguish between bacteria and non-bacteria, and it is beneficial to judge the degree of tissue inflammation or injury Observe the patient's response to treatment and postoperative detection. And the rapid determination of CRP can be used to quickly guide clinical medication and avoid the abuse of antibiotics for patients with vira...

Problems solved by technology

[0004] However, at present, most of the semi-automatic immunofluorescence analyzers used to detect CRP include only the detection unit and its control system, from the absorption of blood samples, the mixing of samples and buffer solutions, the addition of mixed solutions to test strips, and the feeding of test strips. The detection positions are all manually operated, with a heavy workload and low efficiency. Especially when there are a large number of blood samples to be tested, it is inevitable that the results will be inaccurate due to human error, which will affect the doctor's screening of the patient's inflammatory process.
