Title:
DEVICE AND METHOD FOR EVALUATING BLOOD COAGULATION ON BASIS OF LAMB WAVE
Document Type and Number:
WIPO Patent Application WO/2019/088386
Kind Code:
A1
Abstract:
A device for evaluating blood coagulation on the basis of a Lamb wave, according to one embodiment, comprises: a piezoelectric substrate having one surface on which a blood sample from which calcium has been removed and a coagulation reagent are loaded; and a voltage application unit, which applies an alternating current voltage to the piezoelectric substrate so as to generate Lamb waves, wherein an internal flow of the blood sample can occur by the Lamb waves generated from the piezoelectric substrate, and the blood sample and the coagulation reagent are mixed by the internal flow such that the blood sample is coagulated.
