In the following description, a large amount of details is provided the present invention can be understood up hill and dale.But those skilled in the art can understand, following description only relates to preferred embodiment of the present invention, and the present invention can be implemented without the need to one or more such details.In addition, in order to avoid obscuring with the present invention, technical characteristics more well known in the art are not described.
Conveniently PPG signal and ECG signal are monitored, a kind of signal acquisition method is provided.Fig. 1 shows the flow chart of signal acquisition method 100 according to an embodiment of the invention.As shown in Figure 1, signal acquisition method 100 comprises the following steps.
In step S110, pulse monitoring device is utilized to gather PPG signal.Pulse monitoring device can be the device being similar to conventional blood oxygen saturation probe (referred to as " blood oxygen probe ").Such as, pulse monitoring device can comprise photo-electric pulse transducer.Photo-electric pulse transducer is the sensor made according to photoplethymograph, and it can go out PPG signal by carrying out indirect detection to the detection of finger tip absorbance.Photo-electric pulse transducer has that structure is simple, not damaged, the feature such as reproducible.Photo-electric pulse transducer can be transmission-type or reflection pulse sensor.Photo-electric pulse transducer comprises transmitting illuminant and light-sensitive device.Be described for transmittance type pulse sensor below.When the finger tip of monitored target is placed in pulse monitoring device (being worn on the finger of monitored target by pulse monitoring device), the transmitting illuminant (such as light emitting diode etc.) in transmittance type pulse sensor and light-sensitive device (such as light sensitive diode etc.) are distributed in the relative both sides of finger tip.Transmitting illuminant can send the invisible infrared light that visible red that wavelength is 660nm and wavelength are 920 ~ 950nm.When these two kinds of illumination are mapped on the finger tip of monitored target, the light-sensitive device of opposite side can receive transillumination and transillumination is converted to the signal of telecommunication.Subsequently, pulse monitoring device can carry out subsequent treatment to this signal of telecommunication, such as amplification, filtering etc., and then obtains PPG signal.
Next, in step S120, PPG signal wireless is transferred to the main monitoring device gathering ECG signal.Any suitable wireless transmission method can be passed through by PPG Signal transmissions to main monitoring device.This wireless transmission method can be such as 2.4G transmission, Wireless Fidelity (WiFi) transmission, Bluetooth transmission, infrared transmission etc.
Next, in step S130, in main monitoring device, PPG signal and ECG signal are aimed on a timeline.Need certain hour because PPG signal wireless is transferred to main monitoring device, the ECG signal that the PPG signal that therefore main monitoring device receives collects with it is nonsynchronous on a timeline.In order to comprehensive monitoring and analysis can be carried out to PPG signal and ECG signal, need PPG signal and ECG signal to be carried out synchronously, namely aim on a timeline.By PPG signal and ECG signal being carried out aim at the time difference compensating wireless transmission and cause, can make to reach and the effect having line monitoring system identical with the noinvasive continuous measurement of ECG signal PPG signal.
