System for Recording and Transmission of Physiological Signals by Radio Channel Main Features: Poly-Spectrum-Radio system is intended for the recording and transmission of the physiological signals (ECG and breath rhythm) from a man or an animal by radiochannel on 900 MHz frequency. The recorded signals are displayed on the PC screen located up to 300 meters away from the transmitter in the real-time mode and saved in the transmitter and PC memory. The system allows performing the signals recording from several patients simultaneously. The possibility to save the transmitted signal in the transmitter memory allows to avoid data losses in case of radio traffic blackout.
