Thromboelastography TEG

Abstract

The invention belongs to the field of medical coagulation detection equipment, and relates to a thromboelastography TEG comprising a channel coagulation detection module, a blood sample heating and placing module, an upper and lower cups and lid removing movement module, a cup entering and cup body removing module, and a main control circuit board, wherein the body of a sample cup carries the blood sample, and is placed in the blood sample heating and placing module and driven by the cup entering and cup body removing module to move to the position; the channel coagulation detection module isdriven by the upper and lower cups and lid removing movement module to lift, its rotating spindle extends into the body of the sample cup to rotate, and the sensor detects the change in the angle of the rotating main axis to obtain the blood coagulation change of the blood sample. The thromboelastography TEG provided by the invention can reduce the dependence of the thrombus detection equipment onhuman operation and the requirements on the external use environment, thereby improving the stability of the detection result and improving the detection efficiency.

Description

technical field [0001] The invention belongs to the field of medical coagulation detection equipment, and relates to a thromboelastography instrument. Background technique [0002] The existing thrombelastograph basically uses a suspension wire to measure the change of the shear stress during the dynamic coagulation process. The cup cover, the cylinder of the cup cover is intruded into the cup containing the blood sample, and the cup is installed on the constant temperature control board. As the time increases, the resistance produced by the adhesion of fibrinogen in the blood sample is different, so the power transmitted to the suspension wire through the cylinder on the cup cover is different, reflecting the different data changes on the sensor, so as to achieve the purpose of detecting the coagulation process. [0003] However, there are problems of low measurement accuracy and large multi-channel errors. At the same time, the suspension wire is a high-precision and frag...

AI Technical Summary

Problems solved by technology

Due to the limitation of the structure of the instrument itself, the test environment requires high levelness and verticality, and it is easy to cause inaccurate results, errors or test failures due to vibration and insufficient level of instrument placement;

[0007] Low detection efficiency

At present, the instruments on the market are mainly dual-channel, and there is a certain correlation between the channels. Because of the characteristics of the structure itself, there are a series of problems in order to improve the detection throughput, such as the consistency of channel detection and the overall level of multi-channel. adjustment issues, etc.
