JPS6462122A - Electronic hemomanometer - Google Patents

Abstract

PURPOSE:To make a memory having relatively small capacity usable and to reduce the shape of a hemomanometer as a whole, by normalizing the interval between a predetermined pulse pressure wave and the next generated pulse pressure wave corresponding to a predetermined value and storing the max. value of the respective pulse pressure waves and the normalized interval in a memory. CONSTITUTION:The internal average time of a plurality of pulse pressure waves calculated by an average value calculation means 34 is set to Tav and each interval of a pulse pressure wave is set to Tp and the interval Tp is normalized, for example, in the following four stages. In this case, the normalized value is set to N. That is, at the time of Tp>TavX2, N=3 is set and, at the time of TavX2>=Tp>=TavX1.5, N=2 is set and, at the time of TavX1.5>=Tp>=TavX0.5, N=1 is set and, at the time of Tp >=TavX0.5, N=0 is set. These normalized values are stored in an interval memory 33 in order of generation. Herein, an address memory means 42 stores the addresses respectively corresponding to the max. blood pressure, average blood pressure and the min. blood pressure among the max. value addresses stored in a max. value memory means 23. Each pulse pressure wave max. value read from the max. value memory means 23 is normalized by a normalizing means 24 to be printed on a printer 52.
