D-dimer tester

Abstract

A D-dimer tester comprises a rotary sample application arm, a reagent position, a test position, a double tube pump, a liquid collection tube, a sample position, a microinjection pump and a needle washing position, wherein the sample position, the reagent position, the test position and the needle washing position are in a same working platform. The D-dimer tester provided by the invention is easy to operate, avoids the risk of cross contamination, has high consistency of test results, stable test and high precision, and meets market demands; and the unique alarm function of the D-dimer tester can avoid errors in manual operation, so as to ensure the correctness of test results in a hospital.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a D-dimer tester. Background technique [0002] D-dimer (D-Dimer, D-D) is a specific degradation product of cross-fibrin, and its generation or increase reflects the activation of coagulation and fibrinolytic system. D-dimer is a dimer complex that may be produced during the blood coagulation process of the body, and it is generally not produced or produced in a very small amount in the normal body. In whole blood or plasma, D-D content can be easily detected using antibodies against D-D. D-dimer mainly reflects fibrinolytic function. Increased or positive seen in secondary fibrinolytic hyperfunction, such as hypercoagulable state, disseminated intravascular coagulation, kidney disease, organ transplant rejection, thrombolytic therapy and so on. In recent years, with the continuous improvement of methodology, a variety of simple, fast and sensitive methods suitable...

Problems solved by technology

At present, in the field of D-dimer testing instruments, there are fully automatic D-dimer testers and semi-automatic D-dimer testers. The implementation method of the fully automatic D-dimer tester is to use Fixed partitions, and then inject blood samples and test agents. Due to the large number of partitions, in order to complete the entire automatic detection process, multiple XYZ motion systems frequently run in each separated fixed interval, which also makes the entire instrument test speed slow, and the entire The device is huge and cumbersome, the test accuracy is not high, and it is not easy to control, the failure rate is high, the maintenance is difficult, and the cost is high

The semi-automatic D-dimer tester requires a large labor cost and cannot adapt to the requirements of large test samples and short test time

The fully automatic D-dimer tester is suitable for the test of a large number of samples. Although the semi-automatic D-dimer tester is suitable for the test of a small number of samples, it consumes more manpower and time.
