Cardiovascular blood flow velocity real-time measurement sensor

The invention relates to the technical field of medical detection, and discloses a cardiovascular blood flow velocity real-time measurement sensor which comprises a device body, a viscous layer is arranged at the bottom of the device body, an arc-shaped groove is formed in the bottom of the device body, channels are formed in the two sides of the inner wall of the arc-shaped groove, and springs are fixedly connected into the channels. A first temperature detector is mounted at the bottom of one side of the device body; a second temperature detector is mounted on an arc-shaped groove of the device body; a one-way valve, a data transmission module and a controller are mounted in the device body; an air hole is formed in the arc-shaped groove; the one-way valve communicates with the outside of the device body through an exhaust pipe, the data transmission module is in signal connection with a computer, and a data correction module is arranged on the computer. The blood flow velocity is measured by using thermal
