1. An electronic blood pressure monitor comprising:
- a pressurizing unit to be mounted on a wrist of a subject for applying pressure to the wrist;
a pressure-increase structure for applying to a portion of the wrist above ulna a pressure higher than a pressure applied to a portion of the wrist above radius, the structure being connected to the pressurizing unit;
a pulse wave detecting device for extracting pulse wave data from measured pressure data of the pressurizing unit;
a measuring device for measuring blood circulation dynamics using the pulse wave data; and
a display unit for displaying a result of measurement of the blood circulation dynamics.

Abstract
To provide an electronic blood pressure monitor with increased measurement accuracy at the time of measurement of blood pressure at the wrist. A cuff has a pressure-increase structure for making a pressure to an ulna side of the wrist higher than a pressure to a radius side. The pressure-increase structure is achieved by providing an extrusion having a width narrower than a width of the cuff on the side facing the ulna portion. The extrusion is projected from the surface of the cuff. When the cuff is mounted on the wrist, the extrusion presses the ulnar portion with a pressure higher than an internal pressure of the cuff.
