摘要： A CPU of a blood pressure information measurement device calculates blood pressure from a change in internal pressure of an air bladder used to measure the blood pressure. AI (augmentation index) and Tr (traveling time to reflected wave) are calculated from a pulse wave waveform. A path difference calculation unit of the CPU stores a correction equation to correct a pulse wave propagation distance that is stored in advance, and, by substituting the calculated blood pressure value, AI and the like into the correction equation, corrects the pulse wave propagation distance stored in advance and approximates the pulse wave propagation distance stored in advance to an actual pulse wave propagation distance. A PWV (pulse wave velocity) calculation unit calculates the PWV using the corrected distance.

摘要： A blood pressure measurement device accurately calculates an index useful in determining the degree of arteriosclerosis by accurately detecting a difference in time of appearance of a ejection wave and reflected wave in a blood pressure waveform. The device sets a threshold value based on an index that expresses a characteristic of the blood pressure waveform with respect to the point of appearance of the reflected wave in the blood pressure and estimates a rise point of the reflected wave by calculating an x-coordinate value of a point based on a maximum amplitude of the reflected wave and the threshold value. The device obtains the index of degree of arteriosclerosis by calculating a time difference in appearance between the ejection wave and the reflected wave based on the estimated rise point of the reflected wave.

摘要： In a pulse wave analyzer, a local maximum point of a fourth order differentiated wave of the pulse wave of one beat is acquired, and a maximum point of a reflection wave of the local maximum points of the fourth order differentiation existing in a zone of an original waveform is determined as a starting point of a reflection wave zone that is a first characteristic point. With 10% of the amplitude of the first characteristic as a threshold value, a time point at which the amplitude reaches the threshold value after the relevant point is determined as an ending point of the reflection wave zone that is a second characteristic point. The duration time of the reflection time of the time between the first characteristic point and the second characteristic point is calculated as an index useful in the diagnosis of heart disease.

摘要： A measurement device pressurizes two cuffs in a state in which the cuffs are attached to the distal side and the proximal side of the measurement device, respectively, calculates an AI value or the like based on a pulse wave detected from a change in cuff pressure on the distal side while pressurizing the two cuffs, and determines that avascularization on the distal side has been completed if the AI value or the like has converged. Once it is determined that avascularization has been completed, the cuff pressure on the distal side is fixed, and a pulse wave is detected from a change in cuff pressure on the proximal side in a state in which the distal side is avascularized.
