Title: Blood pressure measuring device and blood pressure measuring program
Inventor: JONES MICHAEL
IPC: A61B5/02
Filed: 2021-03-31
Abstract: To avoid blood pressure measurement with a low degree of accuracy.SOLUTION: A blood pressure measuring device 1 measures a first pulse wave at a first position of an object person 15 and a second pulse wave at a second position whose distance from the heart is larger than that of the first position, obtains a delay time L of the second pulse wave with respect to the first pulse wave on a side close to the heart, and measures a blood pressure using relationships between the delay time and the blood pressure. It is determined whether the delay time of the second pulse wave with respect to the first pulse wave is larger than a reference value Th, and if it is larger than the reference value Th=0.08 sec., the blood pressure is measured from the delay time. If the delay time is the reference value Th or less, accurate blood pressure measurement is not possible so that reporting is executed, for prompting change in the measurement position (the second position) of the second pulse wave.SELECTED DRAWING: Figure 8
