Patient monitor

摘要

A patient monitor monitors information on body condition. The monitor includes a sensor for detecting information on body condition and converting the detected information into an electrical analog signal. The electrical analog signal is converted into digital measured values and sampled by a data processor at a predetermined time interval. Or, the data processor calculates a representative data value from a predetermined number of digital measured values to obtain summary data. Continuity or discontinuity is determined from successive blocks of summary data. A read-write storage for the summary data and two different kinds of delimiters correspond to the cases where the continuity and discontinuity of successive blocks of summary data are identified. The data processor operates to read out and process the stored summary data as a block of summary data covering the oldest date to the first discontinuity delimiter or a block from one discontinuity delimiter to the succeeding discontinuity delimiter and to edit the summary date into a histogram for every block of the summary data.
