This project describes device which is Intelligent Primer Nurse. The device is created on EVO Primer development kit which is extended by three external modules for signal measuring and data transmission. Modules are connected to the development kit by wires to special extension board which provides power supply.
The device measures electrocardiogram (ECG) and photopletysmogram (PPG) signal. These signals are samples and processed by software in development kit. Signals are displayed on a display of the development kit with heart rate frequency which is computed from ECG signal. ECG signal processing and heart rate computing is described in chapter Primer software description.
Device has built in heart rate alarm which detected low and high heart rates. Thresholds which activate heart rate alarm are 50 beats per minute (bpm) and 100 bpm. This alarm informs user about probable heart rate problem which may cause life threatening situation.
The next function is activity alarm which starts when measured user have long inactivity. This alarm works like vigilance button in locomotive. User has to move or clicking primer button after every 30 s for deactivate alarm. Movements are detected by sampling acceleration signal from integrated accelerometer.
Information about heart rate with time mark are logged on flash card about every 4s seconds. If device is connected to computer via Bluetooth, heart rate, selected signal and alarm flags are visualized by special software on PC in real time.
