Abstract
A cuff for blood pressure measuring apparatus, which is made of flexible material, includes an inner surface and an outer surface. The inner surface defines a cylindrical space for a finger to be inserted thereinto, while the outer surface together with the inner surface defines a fluid chamber for applying pressure to the finger. A sensor for detecting pulse wave data can be conveniently place on the inner surface of the cuff and is adapted to detect the reflection of light by an artery. The sensor can comprise of a light-emitting element and a light-sensitive element. The light-emitting element for emitting light at an artery of the finger and the light-sensitive element for receiving the reflected light from the artery are mounted on the inner surface adjacent to each other. A plurality of elements are provided at least either for the light-emitting element or for the light-sensitive element, thereby expanding the detection range of the arterial pulse wave in the finger.
