PROBLEM TO BE SOLVED: To appropriately remove data unnecessary for biological signal analysis.SOLUTION: A biological signal processing device includes a biological signal extraction part 2 for extracting a biological signal (R-R interval) from an electrocardiogram waveform measured by an electrocardiograph 1, an averaging processing part 3 for executing averaging processing for time-series data of the biological signal, an abnormal value determination part 4 for determining whether or not the data of the biological signal extracted by the biological signal extraction part 2 is appropriate based on a difference between the data of the biological signal extracted by the biological signal extraction part 2 and averaging data calculated by using the data of the biological signal and the data of biological signals up to the time immediately before, and an abnormal value processing part 5 for removing the data of the biological signal determined to be inappropriate by the abnormal value determination part 4.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】生体信号の分析に不必要なデータを適切に削除する。【解決手段】生体信号処理装置は、心電計1が測定した心電図波形から生体信号(R-R間隔)を抽出する生体信号抽出部2と、生体信号の時系列データに対して平均化処理を行う平均化処理部3と、生体信号抽出部2で抽出された生体信号のデータとこの生体信号のデータおよび直前の時刻までの生体信号のデータを用いて算出された平均化データとの差に基づいて、生体信号抽出部2で抽出された生体信号のデータが適切かどうかを判定する異常値判定部4と、異常値判定部4で不適切と判定された生体信号のデータを削除する異常値処理部5とを備える。【選択図】 図1
