PHYSICAL CONDITION CHANGE DETECTION DEVICE, PHYSICAL CONDITION CHANGE MANAGEMENT PROGRAM, AND PHYSICAL CONDITION CHANGE MANAGEMENT SYSTEM

摘要

The present invention enables more reliable detection of a change in the physical condition of a subject. A physical condition change detection device 100 for detecting a change in the physical condition of a subject, wherein provided are: a casing; and a respiratory tract change detection unit 120 that is disposed in the casing and that detects a change in the respiratory tract of the subject by detecting the sound of the vibration of tissues, such as muscular tissues and epithelial tissues, the vibration propagating to the body surface of the subject. A microphone is used as the respiratory tract change detection unit, the microphone detecting, from the body surface of the subject, the sound of the vibration of tissues such as muscular tissues. The respiratory tract change detection unit is a microphone that detects the sound of the vibration of tissues from the body surface of the subject.
