| abstract | PROBLEM TO BE SOLVED: To enable an accurate blood flow velocity to be easily measured by anyone other than an expert without collecting blood, and to increase the blood flow velocity by reducing the influence of noise. It is to calculate with accuracy. Transmitting elements 2a and 2b and receiving elements 3a and 3b are arranged along a predetermined direction (for example, the length direction of a venous blood vessel). The transmitting element 6 and the receiving element 7 are arranged along a direction orthogonal to the predetermined direction. The frequency analysis unit 45 calculates the difference between the frequency of the reflected wave received by the ultrasonic sensor 1 and the frequency of the transmitted ultrasonic wave as a first frequency, and the frequency of the reflected wave received by the correction sensor 5. And the difference between the frequency of the transmitted ultrasonic waves as the second frequency. The difference calculation unit 49 calculates the difference between the intensity corresponding to the first frequency and the intensity corresponding to the second frequency as difference information. The angle calculation unit 46 and the velocity calculation unit 48 calculate the blood flow velocity using the calculated difference data. [Selection] Figure 1 |
