Patent ID: 8308648

Claim:
An electronic blood pressure measurement device comprising: a measurement bladder for pressing against a measurement site in a state having a predetermined amount of air sealed, a pressure detection portion for detecting a pressure signal indicating an internal pressure in said measurement bladder, a squeezing portion for exerting an externally applied pressure to said measurement bladder to press said measurement site through said measurement bladder, a storage portion, and a blood pressure calculation portion, configured so that information of cuff compliance property obtained from a change of said internal pressure and volume of said measurement bladder having a predetermined amount of air sealed is stored in advance in said storage portion, said blood pressure calculation portion including a pulse wave amplitude detection portion for detecting a pulse wave amplitude included in said pressure signal detected by said pressure detection portion in a process of changing said internal pressure in said measurement bladder by changing said externally applied pressure to said measurement bladder through said squeezing portion, and a correction portion configured for correcting said pulse wave amplitude detected by said pulse wave amplitude detection portion using said information of cuff compliance property read out from said storage portion, blood pressure being calculated based on said pulse wave amplitude corrected by said correction portion.
