摘要：
FIELD: medicine.SUBSTANCE: invention relates to the medical technology, namely to devices for recording the process of blood coagulation, mainly to thromboelastographs. Coagulation analyzer – thromboelastograph – contains a cuvette 1 with the test liquid 2, floated in the cuvette float 3, mounted on the rod with the ability to make a return-rotary movement, rigidly connected to the float rod, torque sensors 4 and rotation angle 5, series-connected amplifier 6, the phase detector 7 and the recording device 8, as well as the sinusoidal oscillator 9 associated with the rotation angle sensor 5 and the phase detector 7. Coagulation analyzer also contains the subtracter 10 with additional generator 11, connected to one of the inputs of the subtracter 10, the other input of the subtracter being connected to the phase detector 7, and the output of the subtractor is connected to the torque sensor 4. Recording device 8 is configured to fix the difference of the signals of the rotation angle sensor 5: the signal of the maximum amplitude of rotation of the float 3 in the initial period of the analysis and the signal of the current amplitude of rotation of the float 3 during the analysis.EFFECT: invention makes it possible to increase the accuracy and reduce the sensitivity threshold of the instrument for coagulation analysis, simplify the design of the device and reduce the influence of destabilizing factors on the measurement results.1 cl, 1 dwgИзобретение относится к медицинской технике, а именно к устройствам для регистрации процесса свертывания крови, преимущественно к тромбоэластографам.
