Background
The thrombus elastometer is a medical instrument for detecting whether blood can be coagulated normally, the thrombus elastometer is generally required to detect blood coagulation data of a patient before an operation is carried out, whether the blood coagulation process of the patient is normal or not is judged according to the detected blood coagulation data, the operation can be carried out on the patient only under the condition that the blood can be coagulated normally, if the blood coagulation process is abnormal, the blood of the patient cannot be coagulated normally in the operation process, the hemostasis is difficult, and the life of the patient is likely to be endangered.
The physical properties of detecting blood clots are based on the following principle: a specially-made cylindrical blood-holding cup, which is stationary and contains blood, is rotated at a low speed of 4.75 degrees, and the movement of the blood sample is detected by a detection rod immersed in the blood sample. After the fibrin platelet complex adheres the cup and the test stick together, the rotational force generated by the rotation of the cup can be transferred to the test stick in the blood sample. The strength of the fibrin platelet complex can affect the magnitude of the movement of the test stick so that a strong blood clot can synchronize the movement of the needle with the movement of the cup. Thus, the amplitude of movement of the measuring rod is directly related to the strength of the formed blood clot. When the blood clot is retracted or dissolved, the coupling of the test stick to the blood clot is released and the movement of the cup is no longer transmitted to the test stick, the rotation of which is then detected by the sensor.
