Abstract

The invention relates to the field of medical instruments and provides a device and method to adjust an ultrasonic signal transmission direction. The method includes: receiving an ultrasonic echo signal about an ultrasonic transmission signal that is sent by an ultrasonic probe; preprocessing the ultrasonic transmission signal and the ultrasonic echo signal to obtain a frequency deviation signal;acquiring frequency spectrum of the frequency deviation signal, and judging whether the frequency spectrum of the frequency deviation signal is characteristically identical with that of a fetal heartsignal; if not, adjusting the transmission direction of the ultrasonic transmission signal, returning execution according to the ultrasonic transmission signal sent by the ultrasonic probe, receivingan operation of the ultrasonic echo, and stopping adjustment until the frequency spectrum of the frequency deviation signal is characteristically identical with that of the fetal heart signal. The device and method have the advantages that the transmission direction can be automatically recognized and adjusted at the premise that the initial position of the ultrasonic probe or the initial transmission direction of the ultrasonic signal is inaccurate, and it is ensured that the transmission direction of the ultrasonic transmission signal can be aligned with the fetal heart.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to an adjustment device and an adjustment method for an ultrasonic signal transmission direction. Background technique [0002] The most widely used fetal heart rate acquisition method is ultrasonic Doppler heart rate detection method, which uses the principle of echo and Doppler to extract the frequency deviation signal of ultrasonic Doppler, thereby obtaining the fetal heart envelope signal, and A method for obtaining the fetal heart rate from this. This method has been widely used due to its advantages of non-invasiveness and simple operation. [0003] In actual clinical practice, the ultrasonic Doppler heart rate detection method can collect the fetal heart rate signal generated by the heartbeat of the fetus by placing the ultrasound probe of the fetal heart rate monitoring device on the abdomen of the pregnant woman. However, in the pregnant woman's abdomen, in ad...
