Method for processing fetal heart rate curve data and device thereof

Abstract

The invention provides a method for processing a fetal heart rate curve data and a device thereof. The method comprises: obtaining the fetal heart rate curve data during a monitoring period; determining the positions of the first effective fetal heart rate data and the last effective fetal heart rate data in the fetal heart rate curve data; removing the fetal heart rate data before the position ofthe first effective fetal heart rate data in the fetal heart rate curve data; and removing the fetal heart rate data after the position of the last valid fetal heart rate data. The method automatically cuts the first end or the rear end of the fetal heart rate curve, eliminates the operation for medical staff to manually label the data, improves the cleanliness of the fetal heart rate curve, reduces the difficulty for doctors to identify fetal heart rate curves, and improves the efficiency of medical staff.

Description

technical field [0001] The invention relates to the technical field of biomedical signal processing, in particular to a method and device for processing fetal heart rate curve data. Background technique [0002] Fetal heart rate can not only reflect the survival of the fetus, but also judge the reserve capacity and health status of the fetus. With the development of electronic technology, the production of fetal monitors allows people to obtain fetal heart rate information more accurately. The fetal heart rate curve is obtained by using the fetal monitor to monitor the fetus to obtain the changes of the fetal heart rate and continuously trace the curve at the same time. Among them, the fetal heart rate curve can continuously and accurately evaluate the reserve capacity and health status of the fetus, so the fetal heart rate curve has important reference value in the clinical diagnosis of the fetus. [0003] At present, clinically, ultrasound probes are generally used to obt...

Problems solved by technology

[0004] However, subject to the principle defect of ultrasound Doppler technology, some messy data may be generated when the ultrasound probe is moved to find the fetal heart rate and when the ultrasound probe is taken off, which will be different from the fetal heart rate after the real start of monitoring. Doctors may be confused after seeing these data, and may also take these data as official fetal heart rate monitoring data, resulting in misdiagnosis. In order to prevent these useless data from affecting the doctor's diagnosis, nurses often need to be on top of these data Make a mark, but doing so every time for monitoring will increase the workload of medical staff and affect the work efficiency of medical staff
