PROBLEM TO BE SOLVED: To solve the problems that, even while it is recognized that the medical value of a mechanocardiogram is high, it is considered that a mechanocardiogram recording device is not useful for a diagnosis of the circulatory system since the mechanocardiogram recording device is large-sized and is extremely expensive, a measurement performance is bad, measurement can be performed only in a special environment such as a soundproof room with at least two medical professionals, and effective data cannot be obtained for a living body to be measured truly requiring the diagnosis using the mechanocardiogram, or the like.SOLUTION: A biological reaction recording device as small and inexpensive as a notebook type personal computer is capable of measuring an apex cardiography or the like by freely using a two-dimensional pressure sensor capable of simultaneously measuring pressure changes at a plurality of adjacent parts of a living body related to one pulsation to be measured, an electronic device of a personal computer level, and a memory, storing and utilizing the time course of biological information, and displaying the biological information as digital images.COPYRIGHT: (C)2014,JPO&INPIT【課題】 心機図の医学的価値は高いと認められながら、心機図記録装置が大型で極めて高価であり、測定性能も悪く、最低2名の医療専門家がついて防音室のような特殊な環境でしか測定できず、心機図を用いた診断が真に必要な被測定生体にとって有効なデータが得られないなどのため、循環器系の診断に心機図記録装置は有用でないとされていた。【解決手段】 測定する1つの拍動に関して生体の近接する複数箇所の圧力変化を同時に測定することができる2次元圧力センサーとパソコンレベルの電子装置ならびにメモリーを駆使して心尖拍動図等を測定し、生体情報の時間的経過も記憶して利用することができ、デジタル画像として生体情報を表示できるノート型パソコン程度の小型で安価な生体反応記録装置を提供できるようにした。【選択図】 図1
