摘要： A blood pressure measuring cuff according to the present invention includes a pressing cuff which is belt-shaped, is wrapped around a part to be measured, and receives supply of a pressurizing fluid to press the part to be measured. An arterial pressure sensor for detecting pressure applied to an artery passing portion of the part to be measured by the pressing cuff is disposed at a portion of an inner peripheral surface of the pressing cuff which should face an artery of the part to be measured, separately from the pressing cuff.

摘要： A CPU of a blood pressure measurement apparatus configured to be used while attached to a wrist of a measurement subject calculates an inclination angle formed by a forearm of the measurement subject with respect to a reference plane, and a rotation angle about an axis, where the forearm is used as the axis, of the blood pressure measurement device, based on information detected by an acceleration sensor, and uses the distance d between the radial artery and the ulnar artery that pass through the wrist, the inclination angle, and the rotation angle to determine the relative positional relationship between the radial artery and the ulnar artery. In accordance with the relative positional relationship, the CPU guides the measurement orientation of the measurement subject.

摘要： The embodiment provides a blood pressure measurement device equipped with an air bag drive unit, a pressing surface formed with pressure sensors, and a control unit which calculates first blood pressure values on the basis of a first pressure pulse wave that was detected by the pressure sensors, generates calibration data using the first blood pressure values, and calculates second blood pressure values by calibrating, using the calibration data, a second pressure pulse wave that is detected by the pressure sensors in a state that the pressing force is set at an optimum pressing force. The control unit performs the processing of calculating second blood pressure values by calibrating the second pressure pulse wave if detection conditions of the second pressure pulse wave coincide with detection conditions of a pressure pulse wave used for generation of the calibration data.

摘要： In a solenoid valve, a bobbin and a solenoid coil are accommodated in a casing. A rod-shaped plunger is slidably inserted into the bobbin. A core provided with a flow port through which a fluid flows is disposed on one side of the casing. A valve body is attached to one end opposing the flow port of the plunger. In a non-operating period during which a solenoid coil is in a non-energized state, the valve body moves away from the flow port due to the biasing force applied by the biasing portion and another end of the plunger protrudes outward from the casing through the through hole, abuts against lock portions disposed outside of the casing, and is thereby locked. The lock portions can be elastically deformed by an external force such that separation of the plunger and the valve body from the casing is allowed.

摘要： In a fluid control device, a check valve includes a first valve housing and a first diaphragm. The first diaphragm defines a first valve chamber and a second valve chamber. An exhaust valve includes a second valve housing and a second diaphragm. The second diaphragm defines a third valve chamber and a fourth valve chamber. The check valve is opened and closed by a difference in pressure between the first valve chamber and the second valve chamber. The exhaust valve is opened and closed by a difference in pressure between the third valve chamber and the fourth valve chamber.
