PROBLEM TO BE SOLVED: To provide a blood pressure information measuring device correctly measuring pulse wave propagation speed even in a case where a femoral artery or the like has a constriction.SOLUTION: In the measuring device, cuffs are respectively installed on the upper arm and the lower limb (ankle) to measure the blood pressure at the upper arm and the lower limb (S101). The cuffs are also used to measure a pulse wave at the upper arm and a pulse wave at the lower limb with synchronism (S103). Upper arm-lower limb pulse wave propagation speed (baPWV) is determined based on appearing time difference between the two pulse waves (S105, S107). Upper arm pulse wave propagation speed (upper arm PWV) is determined based on appearing time difference between an ejection wave and a reflection wave of the upper arm pulse wave (S109, S111). In a case where the values of these propagation speeds are different (S113: YES), an alarm is given (S115).COPYRIGHT: (C)2010,JPO&INPIT【課題】大腿動脈などに狭窄がある場合であっても、正しく脈波伝播速度を測定できる血圧情報測定装置を提供する。【解決手段】測定装置では、上腕および下肢(足首)の各々に装着されたカフが用いられて、上腕および下肢の血圧が測定される(S101)。また、これらカフが用いられて、上腕の脈波と下肢の脈波とが同期させて測定される(S103)。これら2つの脈波の出現時間差に基づいて、上腕下肢部脈波伝播速度(baPWV)が算出される(S105,S107)。また、上腕脈波における駆出波と反射波との出現時間差に基づいて、上腕脈波伝播速度(上腕PWV)が算出される(S109,S111)。これら伝播速度の値が異なっていた場合には(S113でYES)、警告を報知する(S115)。【選択図】図4
