Method and device for determining probe position in fetal monitoring equipment

Abstract

The invention relates to a method for determining the position of a probe in a fetus monitoring device.The method includes the following steps that fetal heart sound signals in output signals of the probe of the fetus monitoring device are taken out and processed, and a processed and continuous fetal heart wave shapes are obtained; the processed and continuous fetal heart wave shapes are displayed on a display screen of the probe, signal strength of the fetal heart wave shapes is displayed on the longitudinal axis of the display screen accordingly, and the fetal heart wave shapes are distributed in the transverse axis of the display screen according to the taken time sequence of the fetal heart wave shapes.The invention further relates to a device for achieving the method.The method and device for determining the position of the probe in the fetus monitoring device have the advantages that operation is easy, and positioning of the probe is 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 ...

Problems solved by technology

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
