Abstract: A biological information display apparatus includes a pulse wave acquisition part, an index derivation part, a determination part, and a display control part. The pulse wave acquisition part acquires a pulse wave signal obtained by measuring a pulse wave of a subject person along a time axis. The index derivation part derives breathing function indexes which are indexes showing states of breathing function of the subject person. The determination part determines whether at least one of the derived multiple breathing function indexes is in a predetermined range as a range of a threshold showing that the subject person gets worse. When at least one of breathing function indexes is in the predetermined range, the display control part displays progress information showing the progress of multiple breathing function indexes since becoming in the predetermined range by the at least one of breathing function indexes.

Abstract: A main body portion is shaped in a cylinder and formed with an intake port which is a hole through which air from an outside flows into the cylinder. The main body portion has one end, which is provided with one-way valve to impede inflow of air from the outside, and the other end, which is not provided with the one-way valve and through which the subject breathes. The resistance setting unit variably sets a magnitude of an inflow resistance to air flowing into the main body portion. The pressure measurement unit measures a pressure of air moving in the cylinder of the main body portion as the intraoral pressure.

Abstract: An auxiliary testing device assists a testing device for testing a respiratory function of a subject. The auxiliary testing device has a tubular member and a restraining member. The tubular member has a tubular shape and is connected to the testing device. The restraining member restrains a movement of a cheek of the subject.

Abstract: An apparatus for producing a mineral water is provided with a mineral source having a mineral element containing a soluble mineral component. Plain water is supplied to the mineral source. The mineral component dissolves in the plain water when the soluble mineral of the mineral element is brought into contact with the plain water. Ultrasonic waves are applied to the mineral source by an ultrasonic source. The conditions for applying ultrasonic waves to the mineral source is controlled to prepare a mineral water which contain mineral component according to a user's requirements or liking.
