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.

摘要： A sphygmomanometer according to the present disclosure includes a main body that is mounted with a pump and is to be disposed on a dorsal surface of a wrist and a cuff that is to be attached around the wrist. The cuff extends along a circumferential direction of the wrist from an ulnar side end portion of the main body to a palmar surface and is set to a length covering an ulnar artery or a length covering a radial artery beyond the ulnar artery of a wrist having a preset maximum wrist circumference. A fluid is supplied from the pump to the cuff to press the wrist. A blood pressure is calculated based on a pressure of the fluid contained in the cuff.

摘要： A sensor assembly of the present invention includes a fluid chamber. A pressure transmitting fluid disposed facing an artery passing portion of a part to be measured via a film which forms a part of an outer wall of the fluid chamber is accommodated in the fluid chamber. A pressure sensor is provided for detecting pressure of the pressure transmitting fluid as pressure applied to the artery passing portion of the part to be measured. Plate members each having a flat shape along a longitudinal direction of a wrist as the part to be measured are disposed on a side opposite to the part to be measured along the film.
