Thrombelastograph coagulation analyzer and application method thereof

Abstract

The invention provides a thrombelastograph coagulation analyzer and an application method thereof. The thrombelastograph coagulation analyzer comprises a movable supporting part, a fixed supporting part, a connecting part, a rotary shaft, a working magnetic body, a Hall element and a processing unit, wherein one end of the movable supporting part is fixedly connected with the rotary shaft and the other end of the movable supporting part is connected with the fixed supporting part through the connecting part; the movable supporting part is fixedly connected with the working magnetic body; the rotary shaft has rotation relative to the fixed supporting part under a driving effect of detected blood; the rotary shaft drives the movable supporting part to rotate; the movable supporting part drives the working magnetic body to move; the Hall element is connected with the processing unit; the Hall element is used for outputting a detection electric signal according to changes of a magnetic field of the working magnetic body; the processing unit is used for determining blood coagulation data of the detected blood according to the detection electric signal. According to the thrombelastograph coagulation analyzer and the application method thereof, provided by the invention, the accuracy of detecting the detected blood can be improved.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a thromboelastometer and a method for using the same. Background technique [0002] Thromboelastometry is an experimental instrument used to detect blood coagulation in vitro. It monitors the blood coagulation process from the whole dynamic process of platelet aggregation, coagulation and fibrinolysis, so as to obtain the rate of blood coagulation and fibrinolysis and the strength of coagulation. The rate of blood coagulation and fibrinolysis and the intensity of coagulation can be used as the basis for clinical diagnosis of cardiovascular and cerebrovascular diseases. [0003] In the existing thrombus elastometer, a rheostat is connected to the rotating shaft of the thrombus elastometer, the blood to be measured drives the rotating shaft to rotate, and the rotating shaft makes the output resistance value of the rheostat change, and the measured value is adjusted according to t...

AI Technical Summary

Problems solved by technology

[0004] It can be seen from the above description that in the existing thromboelastometry, the resistance value output by the rheostat is changed by the rotation of the rotating shaft, and the change of the blood to be measured is reflected by the resistance value output by the rheostat. However, the rheostat is in use. The temperature will increase, and the increase in temperature will apply the output resistance value, making the detection accuracy of the measured blood lower
