PATCH TYPE WIRELESS FETAL MONITORING SYSTEM

摘要

The present invention relates to a patch-type wireless fetal monitoring, and more specifically maternal discomfort in everyday life patch-like to continue to monitor the fetus without the present invention relates to wireless fetal monitoring. ; patch-like wireless fetal monitoring apparatus of the present invention, is attached to the mother's abdomen to detect the living body electric signal of the mother patch-type for detecting bioelectric signals as the converted maternal abdominal ECG signal and the detection module, the patch-like made from the maternal abdominal electrocardiogram bioelectrical signals received from the detection module to the mobile terminal for analyzing the electrocardiogram signal of the fetus is detected. ; The patch-like abdominal ECG detection module, which consists of two electrode array: an electrode portion for detecting a biometric signal from the mother's abdomen to; Signal detector for amplifying the electrode parts from the detected physiological signal and removing noise; A / D converter for converting an output signal of the signal detector to a digital signal; The microcontroller unit for converting the A / D converter of the output signal to a signal range that satisfies the communication protocol can be a Bluetooth transmission (MCU); Bluetooth transmitter configured to transmit an output signal of the microcontroller unit over the air; A battery unit which includes a small battery; characterized by having a ; The portable terminal is a Bluetooth receiver that receives the output signal of the patch-like abdominal electrocardiogram detected by the wireless module; Signal pre-processor removes noise from the output signal of the Bluetooth receiver and to extract and separate each of the ECG signal and maternal ECG signal from the fetus; A central processing unit for diagnosing the condition of a fetus from fetal electrocardiogram signal output from the signal pre-processing unit to determine whether the fetus and the critical state, the compression of the electrocardiogram signal of the fetus and the ECG signal outputted from the signal pre-processing unit the mother; ECG signal from the mother to the center of the compressed processing, a memory unit receiving and storing ECG signals from the fetus; Maternal ECG signal from the central processing unit, fetal ECG signal, a display for displaying information to receive the health of the fetus; Sounding an alarm to alert in response to a control signal indicating that the fetus is critical state generated from the central processing unit; Fetal heart rate, maternal ECG signal, setting unit for setting the system parameters of the fetal electrocardiogram signal; A battery unit which includes a small battery; characterized by having a
