Reagent presetting device for thrombelastogram instrument

Abstract

The invention provides a reagent presetting device for a thrombelastogram instrument. The device comprises a presetting device body installed in the thrombelastogram instrument. The presetting devicebody comprises a blending assembly, an object sensing assembly, at least one reagent container for containing reagents, a first fixing seat and a second fixing seat. The second fixing seat is a framestructure; the reagent container is fixed on the first fixing seat, and the first fixing seat is placed on the second fixing seat; the blending assembly is arranged in the second fixing seat frame body and corresponds to the reagent container in position; the object sensing assembly is arranged on the second fixing seat; and the blending assembly is used for uniformly mixing the reagents in the atleast one reagent container, and the object sensing assembly senses whether the first fixing seat is placed or not. Whether the first fixing seat containing the reagent container is placed or not canbe known through the object sensing assembly, and losses of collected blood samples are avoided. And the reagents needing to be uniformly mixed are stirred through the blending assembly so that accuracy of a detection structure is guaranteed.

Description

technical field [0001] The invention relates to the technical field of clinical coagulation analysis, in particular to a reagent presetting device for a thromboelastography instrument. Background technique [0002] Thromboelastography is a medical device used to detect whether blood can coagulate normally. It detects the coagulation process from the whole dynamic process of platelet aggregation, coagulation, fibrinolysis, etc., and reflects the dynamic changes of blood coagulation (including the formation speed of fibrin, Dissolution state and coagulation firmness, elasticity) indicators. [0003] Usually, the blood is collected in a cuvette, and then further operations such as liquid preparation, liquid separation, dilution, and detection are performed. Among them, the detection requires the use of relevant reagents for coagulation analysis to initiate blood coagulation, which requires the reagents to be put into the relevant device of the thromboelastography instrument fi...

AI Technical Summary

Problems solved by technology

Some reagents for initiating blood coagulation are easy to precipitate during the placement process. In the existing thrombelastograph, the detection reagents are directly placed in the reagent tubes on the reagent tube rack, and the precipitation of the reagents will lead to inaccurate test results.

In addition, the operation of adding reagents to the thrombelastograph from the outside is usually done manually, and it often happens that people forget to put the reagent tubes into the reagent tube slots while the thrombelastograph is still operating, which will cause Loss of collected blood samples and material loss
