technical field

The invention relates to the technical field of blood sample testing, in particular to a multi-channel thromboelastography instrument for testing blood samples and a usage method.

Background technique

Thromboelastography is a non-invasive diagnostic instrument that assists clinicians to make accurate judgments on the coagulation status of clinical patients. By monitoring, testing, and analyzing the coagulation process of the blood sample, the blood coagulation parameter information obtained can make qualitative and quantitative predictions of the coagulation status of the patient. Coagulation assessment is commonly used to predict clinical conditions such as postoperative bleeding, thrombosis during or after cardiac surgery, organ transplantation, trauma, and thrombosis during or after cardiac surgery.

At present, most of the existing thrombelastographs are based on two-channel detection, and a few four-channel instruments simply add channels, which cannot flexibly expand channels. Other functions have not been greatly improved, and the detection cycle is still long. The operation is still cumbersome, the labor intensity is very high, and the operator's proficiency is required to be higher, which is very unfavorable for completing a large number of detection tasks.

At the same time, the lines between various instruments are complicated, and wireless interconnection cannot be achieved, which is very inconvenient to use. In addition, the installation of existing instrument accessories is cumbersome, and the intelligence and integration are not high, which is not conducive to use.
