Abstract
A vessel state measuring device comprises a signal transceiver and a control module. The signal transceiver has a tunnel structure for setting a part to be tested. The signal transceiver at least outputs a first electromagnetic signal to the part to be measured towards the tunnel structure to generate eddy current at the part to be measured, and receives a second electromagnetic signal generated by the corresponding eddy current. The control module is coupled with the signal transceiver, and the control module includes a signal generation unit and a processing unit. The signal generation unit is used to generate AC signals and provide them to the signal transceiver to generate the first electromagnetic signal. The processing unit calculates a characteristic signal according to the first electromagnetic signal and the second electromagnetic signal. The characteristic signal corresponds to at least one state of at least one blood vessel at the part to be measured.
