Title: Sphygmomanometer
Inventor: YOSHIDA HIROAKI
IPC: A61B5/0225
Filed: 1987-08-07
Abstract: PURPOSE:To reduce the extent of regulation to thereby lower the load on a motor pump, by raising the air pressure in a cuff to a predetermined level necessary for sphygmomanometry, discharging the air at a constant rate, increasing, if necessary, the rate of constant rate evacuation with auxiliary constant rate evacuation means and at the same time complementing the air pressure by a booster means. CONSTITUTION:Blood pressure is measured while evacuating a cuff with a constant rate evacuation valve 23, and the rate of constant rate evacuation, S1, is compared with a preset evacuation rate, S0, by means of a pressure sensor 25 and a microprocessor 26 without interruption. When the S1 value is greater than the S0 value, the air is supplied to the cuff by means of a motor pump through am amplifier to bring the S1 value near to the S0 value. On the contrary, when the S1 value is smaller than the S0 value, auxiliary constant rate evacuation valves 23a and 23b are opened to facilitate evacuation to thereby bring the S1 value near to the S0 value. As a result, the S1 values form a straight line approximating to that of the S0 values over a wide range from a high air pressure to a low air pressure, thus enabling accurate determination of both systolic and diastolic pressures in sphygmomanometry.

CONSTITUTION:A voltage divider 1 generates 2<m-n> (where m, n are positive integers, m>n) sets of reference voltages offset sequentially at an equal interval (in this case, let m be 10 and n be 8). The voltage divider 1 divides the reference voltage Vref into four voltages and offsets them by 1/4 each. The voltages are reference voltages of differential amplifiers 6-9 (amplification factor 4), and the amplifiers 6-9 generate a differential voltage from an input voltage Vi. The four outputs of the amplifiers 6-9 are given to an 8-bit 4-input A/D converter 3, were they are A/D-converted and the result is given to a processor type additional circuit 4 as 8-bit data. The circuit 4 receives only the digital signal from the amplifier, e.g., 7 and adds the bit information specific to the differential amplifier 7 to the most significant bit location of the digital value. Thus, 10-bit A/D conversion is to be implemented.
