PROBLEM TO BE SOLVED: To provide a compact blood pressure measurement device capable of measuring without any constraint, and a data management system.SOLUTION: A blood pressure measurement system 1 is configured to reflect not only a time parameter of a pulse wave waveform measured by a pulse wave sensor 5, but also a phenomenon in which the pulse wave is generated by shrinkage and expansion of a blood vessel which is reflected on a data processing device 3 which is additionally provided, for determining a maximum blood pressure value and a minimum blood pressure value.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】小型かつ完全に非拘束により測定可能な血圧測定装置及びデータ管理システムを提供する。【解決手段】血圧計測定システム1においては、脈波センサ5によって測定した脈波波形の時間パラメータのみならず、別体に設けられたデータ処理装置3において、血管の収縮と拡張によって脈波が形成される現象も反映させて最大血圧値及び最小血圧値を求める。【選択図】図1
