Description

Technical Field

[0001] The utility model relates to the technical field of thromboelastographs, in particular to a sampling device for thromboelastographs. Background Art

[0002] Thromboelastograph is a medical device used to detect whether blood can coagulate normally. It detects the coagulation process from the whole dynamic process of platelet aggregation, coagulation, fibrinolysis, etc. It is an indicator that reflects the dynamic changes of blood coagulation (including the formation speed of fibrin, the dissolution state and the firmness and elasticity of the coagulation). Usually, the blood is collected in a reaction cup, and then further liquid preparation, liquid separation, dilution, detection and other operations are performed. Among them, the blood clot sample detected by the thromboelastograph needs to be taken out for the next comparison. The current sampling device of the thromboelastograph needs to use a mechanical arm to take the sample off the reaction cup on the thromboelastograph and send it to the next device for comparison, which is inconvenient to operate.
