However, this method has certain defects: first, it is more complicated for the user to operate, and the fetal heart sound needs to be turned off when finding a suitable fetal heart rate position, which increases the workload of the user; secondly, when the fetal heart sound is turned on, It will disturb other pregnant women who are being monitored; third, there will be a certain delay in playing fetal heart sounds for wireless devices, which will lead to inaccurate fetal heart positions; finally, this method is different for different devices or different For the operator, the results will be different, which also makes the location of the fetal heart rate inaccurate

Embodiment Construction
[0030] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0031] Such as figure 1 As shown, in the method and device embodiment for determining the position of the probe in the fetal monitoring equipment of the present invention, the method includes the following steps:
[0032] Step S11 obtains the fetal heart sound signal, and obtains the fetal heart sound waveform after processing: In this step, the fetal heart sound signal is obtained from the ultrasonic probe installed on the fetal monitor or fetal monitoring equipment, and processed to obtain the fetal heart sound waveform. In fetal monitoring, the ultrasonic probe is usually placed on the abdomen of the pregnant woman. Before starting the monitoring, it is usually necessary to move the position of the above-mentioned probe in the pregnant woman's service to align it with the fetal heart, so as to obtain more accurate fetal heartbeat data. Because the pr...

The invention relates to a method for determining the position of a probe in a fetal monitoring device, which includes the following steps: taking out the fetal heart sound signal from the signal output by the probe of the fetal monitoring device being placed, and processing it to obtain the processed, continuous the fetal heart waveform; the processed, continuous fetal heart waveform is displayed on the display screen on the probe, so that the signal strength of the fetal heart waveform is displayed on the vertical axis of the display screen, and the The fetal heart rate waveforms are distributed along the horizontal axis of the display screen according to the time sequence in which they are obtained. The invention also relates to a device for implementing the above method. Implementing the method and device for determining the position of the probe in the fetal monitoring equipment of the present invention has the following beneficial effects: the operation is relatively simple, and the positioning of the probe is relatively accurate.
Description
technical field [0001] The present invention relates to medical equipment, more specifically, to a method and device for determining the position of a probe in fetal monitoring equipment. Background technique [0002] Fetal heart rate is an important parameter for pregnant women or medical staff to judge whether the fetus in the abdomen is healthy or not. Fetal heart rate is an important means of predicting fetal safety. Pregnant women usually have to go to the hospital for prenatal checkups after 28 weeks, including using fetal monitoring equipment to monitor pregnant women. During the monitoring process of about 30 minutes, the doctor judges whether the fetus is normal based on the fetal heart rate curve printed by the monitor. Before doing the above-mentioned fetal monitoring, the medical staff need to set a sensor probe on the abdomen of the pregnant woman (usually tied to the abdomen through a belt), and the sensor probe converts the collected ultrasonic signal into an ...
