Abstract

The invention provides a thromboelastography instrument and a use method thereof. The thromboelastography instrument comprises a movable supporting portion, a fixed supporting portion, a connecting portion, a rotating shaft, a working magnet, a Hall element, a magnetic shielding unit and a processing unit; one end of the movable supporting portion is fixedly connected with the rotating shaft, and the other end of the movable supporting portion is connected with the fixed supporting portion through the connecting portion; the movable supporting portion is fixedly connected with the working magnet; the rotating shaft rotates relative to the fixed supporting portion under the driving action of detected blood; the rotating shaft drives the movable supporting portion to rotate; the movable supporting portion drives the working magnet to move; the Hall element is connected with the processing unit; the magnetic shielding unit shields influences of external magnetic field on the Hall element and the working magnet; the Hall element outputs a detection electric signal according to the magnetic field change of the working magnet; and the processing unit determines the blood clotting data of the detected blood according to the detection electric signal. The detection accuracy of the detected blood is improved in the invention.

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. If the blood coagulation is abnormal, the blood will not coagulate normally, making it difficult to stop bleeding, which may be life-threatening. Therefore, it is very important to accurately detect the hemagglutination data of blood. [0003] In the existing thromboelastometry, the coagulation state of blood i...
