Blood pressure measuring device

A blood pressure measurement device includes: a base; a flow path cover that is fixed to the base and defines a flow path portion with reference to the base; a recess including an outer surface which is on a base side of the flow path portion and part of which is projected toward the base, and an outer surface which is on a side opposite to the base side and part of which is depressed toward the base; a nozzle that is that is formed on a bottom surface of the recess and communicates with the flow path portion; and a bag-shaped cuff that is connected to the nozzle and that is inflated when a fluid is supplied to an internal space.

An electronic valve with: a yoke including an end plate portion and a side plate portion; a pole piece; a solenoid coil; and a diaphragm made of a plate-shaped magnetic material. The pole piece has an opening at one end portion and a first fluid inlet/outlet communicating with the opening at the other end portion. A biasing unit biases the diaphragm in a direction away from one end portion of the pole piece in a manner of moving the diaphragm translationally in one direction. In a non-operating time, the electronic valve comes into an open state where the opening is open. In an operating time, the diaphragm approaches the one end portion of the pole piece against the biasing force of the biasing unit by a magnetic force generated by the solenoid coil, and the electronic valve can come into a closed state where the opening is closed.

Electronic valve, sphygmomanometer, and apparatus

The present invention provides a sphygmomanometer that can create, before measuring a blood pressure, a state for making a blood pressure measurement accurate. A sphygmomanometer includes a fluid circuit and a control unit. The control unit has a first preparation processing unit, a second preparation processing unit, and a measurement processing unit which operate in a worn state of the sphygmomanometer. The first preparation processing unit operates a pressing cuff to discharge remaining fluid in a sensing cuff to the atmosphere through the fluid circuit. Then, the second preparation processing unit causes the sensing cuff to store a predetermined amount of pressure transmitting fluid received from a pump through the fluid circuit. Subsequently, the measurement processing unit operates the pressing cuff and calculates the blood pressure by the oscillometric method based on pressure of the pressure transmitting fluid stored in the sensing cuff.
