題点があつた。 Conventionally, methods include detecting the fetal heartbeat using an ultrasound diagnostic device and measuring the heart rate visually, or measuring the fetal heart rate by pointing a fetal heart rate measuring device with a Doppler transducer in the general direction of the fetal heartbeat. There is.
The former is usually measured using a stopwatch, etc., but errors are likely to occur when accurately grasping the image and measuring the accurate heart rate.The latter is time-consuming and difficult to detect the heartbeat. Each of them had problems that needed to be solved, such as difficulty in picking up clear signals.

A linear electronic scanning ultrasonic diagnostic device,
A type in which a large number of vibrating elements are arranged in a straight line, pulses are emitted simultaneously from a group of a certain number of vibrating elements, the echoes are received by the same vibrating element, and then the next group of vibrating elements is operated in the same way. To things,
A fetal heart rate measuring device comprising a Doppler transducer that moves parallel to the probe in conjunction with the transducer group conversion is attached, and a heartbeat is detected from the echo of any of the transducer groups. If the position is confirmed (for example, as a result of moving from α to β as shown in the figure), the Doppler transducer turns on the Doppler and emits continuous waves, receives the Doppler signal, and sends the signal to the main body of the ultrasound diagnostic equipment. It can be processed by a built-in computer to accurately measure heart rate.

心拍数を正確に計測しうるものである。 As shown in FIG. 2, the characteristic part of the present invention is that the transducer group 2,
The present invention is an ultrasonic diagnostic apparatus equipped with a fetal heart rate measuring device 4 comprising a Doppler transducer 3 interlocked with 2'. When a heartbeat is extracted on the cathode ray tube by one of the scanning transducer groups 2n , a switch of the fetal heart rate measuring device 4, which is electronically or mechanically linked from α to β, is activated at the position of the scanning element group. By pressing , the Doppler transducer turns on, emits continuous waves, and receives the Doppler signal, which can be processed by a microcomputer or the like as described above to accurately measure the fetal heart rate.
