Patent ID: 8764669

Claim:
A blood pressure information display device for calculating a blood pressure value, and displaying the calculated blood pressure value as blood pressure information, the blood pressure information display device comprising: a display unit; an operation unit for accepting an operation by a user; a cuff to be wrapped around a predetermined measurement site of a person to be measured; an adjustment unit for adjusting an inner pressure of the cuff; a pressure detection unit for detecting a cuff pressure signal representing the pressure in the cuff; an acquiring unit for acquiring the cuff pressure signal in time-series from the pressure detection unit when a drive control of the adjustment unit is being carried out; an extracting unit for extracting a pulse wave amplitude for every beat based on the cuff pressure signal; a display processing unit for displaying pulse wave amplitude information representing a plurality of extracted pulse wave amplitudes on the display unit; a change processing unit for performing a process of changing a magnitude of a specified pulse wave amplitude of the plurality of extracted pulse wave amplitudes according to an instruction from the operation unit when a predetermined instruction is input from the operation unit; and a calculating unit for calculating a reference blood pressure value by applying a predetermined algorithm to a plurality of pulse wave amplitudes reflecting the change on the specified pulse wave amplitude; wherein the display processing unit displays the reference blood pressure value on the display unit as the blood pressure information.
