Abstract

Disclosed is an electronic blood pressure meter which is adapted to measure blood pressure from a finger. A cuff for applying pressure to the finger comprises a plurality of chambers which are communicated to each other and, thereby, provides a sufficient flexibility to closely conform to the contour of the finger. A sensor for detecting pulse wave data may be conveniently place on the inner surface of the cuff and is adapted to detect the reflection of light by an artery. Further, an air buffer can increase the effective air volume of the cuff and can reduce the rate of the pressure drop of the air cuff for a given rate of air vent from the cuff. By deriving the pulse wave data and computing the systolic and diastolic blood pressure therefrom in the course of increasing the air pressure of the cuff, the discomfort to the patient whose blood pressure is to be measured can be substantially reduced.
