Title:
BIOLOGICAL EXAMINATION DEVICE, BIOLOGICAL-INFORMATION ANALYZING METHOD, AND COMPUTER PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/100348
Kind Code:
A1
Abstract:
Provided are a biological examination device, a biological-information analyzing method, and a computer program: that make it possible, by means of a non-invasive examination, to ascertain, at a glance, up-down and front-rear two-dimensional movements of the thyroid cartilage and the hyoid bone accompanied by swallowing sounds as swallowing dynamics; and that make it possible to ascertain, at a glance, a peak position of the swallowing sounds in movement pathways of the thyroid cartilage during swallowing. A biological examination device according to an embodiment of the present invention: identifies, from a fitting result obtained by fitting a model function that models swallowing movements to distance information based on detection data detected by a laryngeal-part displacement detection unit, an up-down movement component associated with an up-down movement of the thyroid cartilage and a front-rear movement component associated with a front-rear movement of the thyroid cartilage; and generates, on the basis of the identified up-down movement component and front-rear movement component, a two-dimensional trajectory data 901 that indicates a behavior trajectory of the thyroid cartilage in an up-down direction and a front-rear direction. In addition, identification display data are generated on the basis of the detection data from a swallowing-sound detection unit, the identification display data making it possible to determine, on the trajectory graph 901, whether the peak of the swallowing sounds is located, in a series of up-down and front-rear movement pathways of the thyroid cartilage during swallowing, in an outward path of the movement pathways, associated with upward and forward movements of the thyroid cartilage, or a return path of the movement pathways, associated with rearward and downward movements of the thyroid cartilage.
