Blood flow parameter measuring device and equipment and storage medium

The embodiment of the invention provides a blood flow parameter measuring device and equipment and a storage medium, and the blood flow parameter measuring device is applied to Doppler blood flow detection equipment. The device comprises a first acquisition module used for acquiring the distance between a first wafer and a second wafer according to the propagation speed of a signal so as to acquire the Doppler included angle of a blood vessel to be detected; the Doppler included angle is an included angle between the signal transmitting direction and the axial direction of the to-be-detected blood vessel; the second acquisition module is used for acquiring a frequency spectrum envelope line of the signal according to a spectrogram of the signal received by the second wafer; and the third acquisition module is used for acquiring blood flow parameters of the to-be-detected blood vessel according to the frequency spectrum envelope and the acquired Doppler included angle of the to-be-detected blood vessel.
