Abstract

To provide a biological examination apparatus and a biological information analysis method which allow a user to grasp the two-dimensional upper, lower, front and back motions of the thyroid cartilage and hyoid bone followed by the deglutition sound as the deglutition dynamics at a glance with a non-invasive examination.SOLUTION: A biological examination apparatus extracts the up-down motion component following the vertical motion of the thyroid cartilage and the front-back motion component following the front-back motion of the thyroid cartilage from a fitting result obtained by fitting a model function that models the deglutition motion to distance information based on detection data detected by a laryngeal displacement detection part, and generates two-dimensional trajectory data 901 which indicates behavioral trajectories in the vertical direction and cross direction of the thyroid cartilage on the basis of the extracted up-down motion component and front-back motion component.SELECTED DRAWING: Figure 10
