PROBLEM TO BE SOLVED: To accurately obtain a pressure parameter related to pressure of blood passing through an artery.SOLUTION: A pressure gauge is provided that comprises: sensor means outputting a pressure parameter related to pressure of blood passing through an artery of a living body to be measure and including a load sensor member pressing means which is located on the opposite side of the living body to be measured with the load sensor member therebetween and presses the load sensor member to the side of the living body to be measured and a support member which positioned between the load sensor member and the pressing means, supports the load sensor member, and has such rigidity that the support member does not deform by the maximum pressure of blood in the artery.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】動脈を通る血液の圧力に関する圧力パラメータを精度良く得る。【解決手段】計測対象生体の動脈を通る血液の圧力に関する圧力パラメータを出力する、荷重センサ部材を含むセンサ手段と、前記荷重センサ部材を挟んで前記計測対象生体と反対側に位置して、前記荷重センサ部材を前記計測対象生体側に押し付ける押圧手段と、前記荷重センサ部材と前記押圧手段との間に位置して前記荷重センサ部材を支える、前記動脈内の血液の最大圧力によって変形しない剛性を有する支持部材と、を具備することを特徴とする圧力計。【選択図】図1
