Patent ID: 8684939

Claim:
A blood pressure measurement device comprising: a cuff, which is configured to be attached to a blood pressure measurement site of a person to be measured and which includes a gas bag filled with gas; a pump for transferring gas to the gas bag; a flow rate control valve for controlling a gas flow rate discharged from the gas bag; a pressure sensor for detecting pressure in the gas bag; a first substrate including a sensor mounting surface and a sensor non-mounting surface, and having the pressure sensor mounted on the sensor mounting surface; a radio-controlled clock, including an antenna for receiving a standard radio wave including time information, for timing a current time; and a second substrate including an antenna mounting surface and an antenna non-mounting surface, and having the antenna mounted on the antenna mounting surface; wherein the pump includes a motor that rotates about an axis line and operates the pump, wherein the antenna includes a bar-shaped magnetic body core and a coil wound around the magnetic body core, wherein the pump is arranged such that an axis line direction of the motor and an extending direction of the magnetic body core are substantially orthogonal; and wherein the first substrate and the second substrate are arranged so that the sensor non-mounting surface and the antenna mounting surface face each other, or so that the sensor mounting surface and the antenna non-mounting surface face each other.
