Abstract

The invention discloses a blood coagulation test system driven by sound waves. The blood coagulation test system driven by sound waves comprises a hollow glass substrate, an interdigital transducer, apiezoelectric plate, a blood movement reaction tank, a detection electrode and an image acquisition and analysis system, and an interdigital electrode is evaporated on the substrate; the piezoelectric plate is placed on the interdigital electrode; an annular blood reaction tank obtained through cutter cutting is in bonding with the piezoelectric plate through surface treatment; the detection electrode is fixed to the reaction tank through a fixing spring; and by adjusting the position of a bracket, it is ensured that the image acquisition system is located at a suitable position, and the movement condition of blood can be recorded in real time. The blood coagulation test system driven by sound waves is simple and convenient in equipment, the integration level is high, required samples areless, energy consumption is lower, the reaction efficiency is high, open type reaction is easy to operate and maintain, and detection and analysis of various parameters in the blood coagulation process can be realized.
