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. |
