Patch type wireless fetal monitoring system

The present invention relates to a patch-type wireless baby monitors, more specifically relates to a patch-type wireless fetal monitoring devices that mothers can continue to monitor the fetus without the inconvenience of daily life. Patch-type wireless fetal monitoring apparatus of the present invention comprises a patch-type abdominal ECG detection module is attached to the abdomen of the mother to detect a biological signal of the mother for detecting a maternal biological electric signal converted into an electrical signal, the patch-like received from the abdominal electrocardiogram detection module the mother is made from the living body electric signal to a mobile terminal for detecting analyze the electrocardiogram signal of the fetus. The patch-type electrocardiogram abdominal detection module, which consists of two electrode array: an electrode portion for detecting a biometric signal from the mother's abdomen; Signal detector for amplifying the biological signal detected from the electrode portion, and removing noise; A / D converter for converting an output signal of the signal detector to a digital signal; The microcontroller unit (MCU) to convert a signal range that satisfies the communication protocol can be a Bluetooth transmission the output signal of the A / D converter; Bluetooth transmitter configured to transmit an output signal from the microcontroller unit over the air; Characterized in that it comprises a; unit battery having a small battery. The portable terminal includes a Bluetooth receiver that receives the output signal of the patch-like abdominal ECG detection module over the air; Signal pre-processing unit for removing noise from the output signal of the Bluetooth receiver and extract respectively separate the ECG signal from the fetal and maternal ECG signal; A central processing unit for diagnosing the status of the fetus from the electrocardiogram signal of the fetus generated from the signal pre-processing unit determines whether the fetus is an emergency condition, and compressing the ECG signal and the fetal electrocardiogram signal of the mother output from the signal pre-processing unit; A memory unit which receives and stores the ECG signal, the fetal electrocardiogram signal of the mother from compression to the central processing unit; From the central processing unit of the maternal ECG, fetal ECG signal, a display for displaying by receiving the health status of the fetus; Alarm an alarm in accordance with the control signal that the fetus generated from the central processing unit indicating that an emergency condition; Fetal heart rate and maternal ECG signal, a setting unit for setting the system parameters of the fetal ECG signal; Characterized in that it comprises a; unit battery having a small battery.
