Abstract

The invention relates to a portable thrombus detection device based on broadband bioelectrical impedance, which is characterized in that the function of detecting thrombus in blood is realized by utilizing the dielectric relaxation difference of the blood under different thrombus states and the change of related broadband electrical impedance parameters. In the detection process, only fingertip blood sampling needs to be conducted on a patient, blood is placed in the detection bin and the contrast bin, broadband bioelectrical impedance signals of blood samples in the detection bin and the contrast bin are detected, data comparison and database analysis are conducted, and the thrombus degree in the blood is calculated. The portable thrombus detection device based on the broadband bioelectrical impedance can achieve portable detection of thrombus, provides convenient and rapid blood thrombus state detection for a large number of cardiovascular disease patients under the increasingly aggravated aging social background in China, and improves the health guarantee of the cardiovascular disease patients in China.

Description

technical field [0001] The invention relates to a thrombus detection device based on broadband bioelectrical impedance. During the detection process, it is only necessary to collect fingertip blood from the patient, place the blood in the detection chamber and the control chamber, measure the broadband bioelectrical impedance signals of the blood samples in the detection chamber and the control chamber, and perform data comparison and database analysis to calculate the blood The degree of internal thrombus. The portable thrombus detection device based on broadband bioelectrical impedance can realize the portable detection of thrombus. Under the background of my country's increasingly aging society, it will provide a large number of patients with cardiovascular diseases with convenient and fast detection of blood thrombus status, and improve my country's heart rate. Health protection for patients with vascular disease. Background technique [0002] Thrombosis is a multifacto...
