Blood pressure monitor and corresponding cuff

Abstract

An air bag (150) being inflated and deflated as air comes in and out is included. The air bag (150) is formed of a flexible sheet material. The air bag (150) has at least an inner circumferential sheet (162) positioned inside when a blood pressure monitor cuff is wrapped around a living body, and an outer circumferential sheet (161) positioned on the outer circumferential side of the inner circumferential sheet (162). The sheet material forming the air bag (150) has a thickness of 0.15 mm or less. Therefore, big deep wrinkles appearing on the inner surface of the fluid bag fitted on a living body can be reduced, which may otherwise give an adverse effect on blood pressure measurement.

Description

technical field [0001] The present invention relates to a sphygmomanometer cuff having an air bag for blocking blood in an artery by compressing a body, and a sphygmomanometer having the cuff. Background technique [0002] Usually, when blood pressure is measured, first, a cuff containing a fluid bag for compressing an artery inside the body is wrapped around the body surface of the body. Then, the arterial pressure pulse wave generated in the artery is detected by pressurizing the wrapped fluid bag and then depressurizing it appropriately. The measurement of the blood pressure value is thereby carried out. [0003] Here, the so-called cuff refers to a hollow belt-like structure that can be wound around a part of the body. Fluids such as gas or liquid are injected into the cuff to measure arterial pressure in the upper and lower extremities of the body. Therefore, a cuff is a term representing a concept including a fluid bag and a wrapping member for wrapping the fluid ba...

Problems solved by technology

In this case, since the artery cannot be compressed stably, it may adversely affect the measurement accuracy.
