Abstract: A physiological information processing method executed by a computer. The physiological information processing method includes acquiring, from a plurality of electrodes attached to a body surface of a subject, a plurality of electrocardiogram signals indicating an electrocardiogram waveform of the subject, separating, through independent component analysis, each of the plurality of electrocardiogram signals into one or more first waveform components indicating the electrocardiogram waveform and one or more second waveform components indicating a waveform other than the electrocardiogram waveform, acquiring an activity evaluation index indicating a respiratory muscle activity amount of the subject based on an electrocardiogram signal that is obtained from a predetermined electrode among the plurality of electrodes attached to the body surface of the subject and from which the one or more first waveform components have been removed, and outputting information on the activity evaluation index.

Abstract: An oral cavity measuring device driven by a battery includes a sensing unit that includes one or more sensors which detect an occlusion state of teeth of a subject, a transmission timing setting unit that sets a data transmission timing based on the occlusion state detected by the sensing unit, and a transmission unit that transmits the occlusion state detected by the sensing unit based on the data transmission timing set by the transmission timing setting unit.

Abstract: An eyepiece optical system, an illuminating lamp, and a battery 2 are housed in an operation unit 2. An insertion unit in which an image transmitting optical fiber bundle and an illumination light transmitting optical fiber bundle are incorporated is detachably coupled with the operation unit through a coupling unit. The insertion unit is bent using a bending wire attached to the distal end thereof and coupled to the operation unit by a wire operating mechanism. An anti-clouding material can be disposed on a surface of the distal end of the insertion unit to protect it against clouding.
