PROBLEM TO BE SOLVED: To solve problems that: a doctor and nurse are forced to use a specific type device since even if k sound is extracted with an electrocardiogram trigger method so that measurement may be carried out even during exercise or hard working, there is a poor noise reduction means, thus there is a case where incorrect blood pressure value is obtained, resulting in that ECG lag of electrocardiograph is unknown and, even if non specific electrocardiograph may be used, since it is unknown that measurement is carried out correctly, the doctor and nurse carry out the blood pressure measurement while confirming the relevance of the blood pressure value at that field by themselves, resulting in time consumption in measurement.SOLUTION: There is provided a sphygmomanometry device having a cardiograph synchronizing function in which vibration generated in blood vessel is extracted by an electrocardiogram trigger method with cardiographic signal. Automatic learning function is provided to a parameter required upon extraction of the vibration. The required parameter is ECG lag specific to an electrocardiograph. ECG lag measurement means is provided to the automatic learning function.COPYRIGHT: (C)2015,JPO&INPIT【課題】運動中や体動が激しい場合でも測定可能となるよう心電図トリガ法を使用してK音の抽出をしても、ノイズ除去手段に乏しく、不正確な血圧値になることがあり、心電計のECGラグは未知であるため、医師や看護師は指定機種の使用を強いられている。また、指定以外の心電計が使用できたとしても、正常に測定できているか不明のため、血圧値の妥当性を医師や看護師自らがその場で確認しながら血圧測定を行っており、測定中の時間を拘束してしまっている。【解決手段】心電信号を用いた心電図トリガ法によって血管から発生する振動を抽出する心電同期機能を設けた血圧測定装置において、前記振動を抽出する際に必要とするパラメータに自動学習機能を設け前記必要とするパラメータが心電計固有のECGラグであり、前記自動学習機能にECGラグ測定手段を設ける。【選択図】図1
