Description
technical field [0001] The invention relates to a magnetic stirring device of a platelet aggregation tester. The device comprises a base, a test cup body and a cup body base. A stirring magnetic bar is arranged in the test cup body; a centripetal drive rotor is arranged under the cup body base. Background technique [0002] At present, the determination of platelet aggregation rate is mostly based on photoelectric turbidimetry. This method is to inject a blood sample into a test cup through a testing instrument, add a platelet aggregation inducer, and then read the platelet aggregate formation process within a specified time. The light transmittance data of the blood sample, and finally form the platelet aggregation rate curve. During the test, the platelet aggregates suspended in the blood sample move irregularly, which is not conducive to the accurate collection of the transmittance data, which requires uniform stirring of the blood sample during the test.
