Problems solved by technology

[0004] Due to the number, position, and depth of the generated wrinkles, the internal space of the cuff may be disconnected, and the expansion pressure may be lost. The wrinkles generated on the cuff will reduce the measurement accuracy of blood pressure and cause deviations in the measurement results, which will affect blood pressure measurement. The main reason for the result

Abstract

The present invention provides a blood pressure measurement apparatus with which it is possible to improve the accuracy of blood pressure measurement results. This blood pressure measurement apparatus(1) is provided with: a sac-like cuff (71) which is to be wound around the body (100) and which inflates when a fluid is fed to the interior thereof; a feed device (3) which feeds a fluid into the cuff (71); and a guide part (84) which is provided on the body (100) side of the cuff (71) and which forms, on the body (100) side of the cuff (71), wrinkles that intersect with the winding direction ofthe cuff (71) when the cuff (71) inflates to exert pressure on the body (100).

Description

technical field [0001] The present invention relates to a blood pressure measuring device for measuring blood pressure. Background technique [0002] In recent years, blood pressure measuring devices for measuring blood pressure have been used not only in medical equipment but also as devices for checking health status at home. A blood pressure measuring device measures blood pressure by wrapping a cuff around an upper arm or wrist of a living body, expanding and contracting the cuff, and detecting the pressure of the cuff with a pressure sensor to detect vibration of an artery wall. [0003] However, when the cuff is wound around a living body to inflate the cuff, there is a difference between the peripheral length of the inflated cuff on the outer peripheral surface side and the peripheral length on the inner peripheral surface side. folds. The number, position, and depth of wrinkles formed on the cuff vary depending on the circumference and shape of the living body arou...
