PROBLEM TO BE SOLVED: To provide a blood pressure manometer capable of displaying the reliability of a computed blood pressure.SOLUTION: A blood pressure manometer (1) includes pulse wave signal acquisition means (5) for acquiring a pulse wave signal, blood pressure computing means (9) for computing a blood pressure based at least on the pulse wave signal, and display means (13) for displaying the information on the reliability including one or more items selected from (a) to (e). That is, (a) a pulse wave waveform, (b) a first order differential waveform of the pulse wave waveform, (c) a second order differential waveform of the pulse wave waveform, (d) an electrocardiographic waveform, and (e) a feature amount acquired from one or more of (a) to (d).COPYRIGHT: (C)2015,JPO&INPIT【課題】算出した血圧の信頼性を表示できる血圧計を提供すること。【解決手段】脈波信号を取得する脈波信号取得手段(5)と、少なくとも前記脈波信号に基き血圧を算出する血圧算出手段(9)と、以下の(a)~(e)から選択される1以上を含む信頼性に関する情報を表示する表示手段(13)と、を備えることを特徴とする血圧計(1)。(a)脈波波形、(b)脈波波形の1階微分波形、(c)脈波波形の2階微分波形、(d)心電波形、(e)前記(a)~(d)のいずれか1以上から得られる特徴量。【選択図】図1
