Description

technical field [0001] The invention relates to the field of flow detection or the field of medical detection equipment, in particular to an ultrasonic flow device used for flow detection in the cardiovascular system. Background technique [0002] Ultrasonic flowmeters are instruments that measure flow by detecting the effect of fluid flow on ultrasonic beams (or ultrasonic pulses). According to the principle of signal detection, ultrasonic flowmeters can be divided into propagation velocity difference methods (direct time difference method, time difference method, phase difference method) method and frequency difference method), beam offset method, Doppler method, cross-correlation method, spatial filtering method and noise method, etc. Ultrasonic flowmeter has many characteristics, such as unique signal digital processing technology, which makes the instrument measurement signal more stable , The measurement is more accurate. [0003] The existing ultrasonic flow device f...
