Abstract
A handheld vascular state measurement device includes a shell, a coil set, and a control module. The shell has a probe part and a handheld part. The coil set is arranged on a measurement surface of the probe part and includes a plurality of coils. The control module is coupled to the coil set. The control module is configured to drive the plurality of coils of the coil set to perform an eddy current induction measurement on a target vessel to derive a plurality of sensing signals corresponding to the plurality of coils. Two of the plurality of sensing signals have a signal characteristic difference. The control module evaluates at least one vascular state of the target vessel based on the signal characteristic difference.

A handheld vascular state measurement device, comprising:
- a shell having a probe part and a handheld part;
- a coil set arranged on a measurement surface of the probe part, the coil set including a plurality of coils arranged in a line with a fixed pitch along an extending direction;
- and
- a control module coupled to the coil set, wherein the control module is configured to drive the plurality of coils of the coil set to perform an eddy current induction measurement on a target vessel to derive a plurality of sensing signals corresponding to the plurality of coils,
- wherein the control module is further configured to determine a signal characteristic difference between two of the plurality of sensing signals that are derived substantially simultaneously from different locations along the extending direction, and evaluates at least one vascular state of the target vessel based on the signal characteristic difference.
