Non-contact vascular stenosis detection device

Abstract

A non-contact vascular constriction measurement device includes a base, a measurement chamber, and a radar detection module. A rotating chamber of the measurement chamber is rotatably mounted on the base. At least one detection radar of the radar detection module is mounted on the rotating chamber. The detection radar rotates with the rotating chamber and is used to emit at least one radar wave to a limb inserted in the rotating chamber to detect the vascular constriction state and blood flow state of the blood vessels in the limb.

Claims
