Abstract

The invention discloses a thrombus elasticity testing device. The thrombus elasticity testing device comprises a supporting plate, a measuring unit, a driving unit and a cup holding unit, wherein the measuring unit and the driving unit are arranged on the supporting plate, and the cup holding unit is connected with the driving unit; the measuring unit comprises a base, a rotating part, a rotating shaft and a balance spring. According to the thrombus elasticity testing device, the driving unit is combined with the cup holding unit to carry out regular vibration on a blood sample in a measuring cup to simulate a physiological thrombus formation environment in vivo, thereby guaranteeing an accurate and reliable test result; by virtue of a structure consisting of the conical tip-shaped rotating shaft and the balance spring in the measuring unit, friction generated during vibration of the measuring unit is decreased sharply, and the shock resistance of the complete device is greatly improved on the premise of guaranteeing restoring force, so that the measurement reliability is high; by virtue of an optical lever measuring mechanism, the resolving ability and sensitivity of thrombus elasticity measurement are effectively increased, so that the measuring accuracy is remarkably improved; by virtue of a measuring cup loading-unloading mechanism, the operation is convenient and reliable.

Description

technical field

[0001] The invention relates to the technical field of clinical coagulation analysis, in particular to a thrombus elasticity testing device. Background technique

[0002] Blood coagulation is blood coagulation, which refers to the process of blood changing from a flowing liquid state to an immobile gel state. It is an important part of physiological hemostasis. The essence of blood coagulation is that soluble fibrinogen in plasma changes into insoluble fiber protein process. Thromboelastography is used in clinical testing and is one of the important tools for detecting blood coagulation. The existing thrombus elasticity test device has complex structure, cumbersome data processing, and low stability of measurement accuracy. Therefore, it is necessary to develop a thrombus elasticity test. The device meets the requirements of today's clinical coagulation detection and analysis. Contents of the invention
