测定脉搏波传播速度作为血压信息的血压信息测定装置
摘要：
在测定装置中，利用分别装戴在上臂和下肢(脚腕)的袖带来测定上臂的血压和下肢的血压(S101)。而且，利用这些袖带同步地测定上臂的脉搏波和下肢的脉搏波(S103)。然后，基于这两个脉搏波的出现时间差，计算上臂下肢部脉搏波传播速度(baPWV)(S105、S107)。而且，基于上臂脉搏波的射血波和反射波的出现时间差，计算上臂脉搏波传播速度(上臂PWV)(S109、S111)。在这些传播速度的值不同时(S113：是)，发出警告(S115)。
摘要（英）：

In a measuring device, the blood pressure in an upper arm and the blood pressure in a lower extremity (ankle) are measured using cuffs which are respectively mounted on the upper arm and the lower extremity (S101). The pulse wave in the upper arm and the pulse wave in the lower extremity are synchronized and measured using the cuffs (S103). The pulse wave velocity between the upper arm and the lower extremity (baPWV) is calculated on the basis of the time difference between the timings at which the two pulse waves (S105, S107) respectively appear. The pulse wave velocity in the upper arm (upper arm PWV) is calculated on the basis of the time difference between the timings at which the ejection wave and the reflected wave in the pulse wave in the upper arm (S109, S111) respectively appear.When the values of the wave velocities are different (YES in S113), a warning is reported (S115).
