    Receiver, pulse signal is traced for obtaining electrocardiosignal and light Volume Changes；
    Processor, actual measurement blood pressure is determined for tracing pulse signal according to the electrocardiosignal and the smooth Volume Changes；
    Transmitter, for sending the actual measurement blood pressure to transmission side apparatus, predicting equation formula for the transmission side apparatus according to the actual measurement blood pressure with determining pre- measuring blood pressure, is corrected to the coefficient of the predicting equation formula, and calculates pressure value according to the predicting equation formula after correction.
  21. One kind sends side apparatus, it is characterised in that including：
    Receiver, pulse signal is traced for obtaining light Volume Changes；
    Transmitter, reception side apparatus is sent to for the smooth Volume Changes to be traced into pulse signal, and tracing pulse signal according to electrocardiosignal and the smooth Volume Changes for the reception side apparatus determines actual measurement blood pressure；
    The receiver, for receiving the actual measurement blood pressure that the reception side apparatus is sent；
    Processor, for the predicting equation formula according to the actual measurement blood pressure with determining pre- measuring blood pressure, is corrected, and calculate pressure value according to the predicting equation formula after correction to the coefficient of the predicting equation formula.
