Problems solved by technology
VE is simpler than VF, but it causes discomfort to the subject such as inserting an optical fiber through the nasal cavity, and requires a fiberscope device, so it cannot be easily measured, and it has not yet been widely used.
Furthermore, there is also the following problem: when the food piece enters the pharynx and reaches the climax of swallowing, the pharynx wall is blocked and the space in the pharynx is squeezed, the field of view of the endoscope becomes unclear and the swallowing organ is short-term. The time band with the largest shift in time cannot be observed

Embodiment 1
[0034] figure 1 is a functional block diagram of the living body information analysis system in this embodiment. Such as figure 1 As shown, the biological information analysis system in this embodiment includes a measurement unit 1 and a biological information analysis device 2 .
[0035] The measuring unit 1 is an elastic holder worn by the user when performing measurement, and includes a transmitting coil (larynx displacement detection unit) 101, a receiving coil (larynx displacement detection unit) 102, and a microphone 103, the transmitting coil 101 and the receiving coil. The coils 102 function as a pair as a distance information acquisition unit for measuring distance information of the displacement of the larynx as the movement of the larynx accompanying swallowing. The transmission coil 101 and the reception coil 102 are connected to an inter-coil voltage detection unit 104 , and an output voltage of the inter-coil voltage detection unit 104 is input to a measurement...

The purpose of the present invention is to obtain a biological information analysis device, a biological information analysis method, and a biological information analysis system that enable more accurate determination of a swallowing motion. In order to attain the purpose, this biological information analysis device has: a swallowing motion assessment unit which assesses a user's motion by analyzing distance information and sound information that are obtained by measuring the motion and sound of the pharynx region; and a display unit, wherein the swallowing motion assessment unit is configured to output a first swallowing motion position that is assessed by analyzing the distance information and a second swallowing motion position that is assessed by analyzing the sound information, and the display unit is configured to display the distance information, the sound information, and the first swallowing motion position and the second swallowing motion position outputted by the swallowing motion assessment unit.
Description
technical field [0001] The present invention relates to a biological information analysis device, a biological information analysis method, and a biological information analysis system. Background technique [0002] Impairment of the swallowing function, which is a function of sending a food mass to be swallowed from the oral cavity into the stomach, is caused by a decrease in motor function due to aging, brain disease, and the like. When dysphagia occurs, food lumps are mixed into the trachea, lungs, etc., causing pneumonia, etc., and sometimes high fever occurs, which is considered to be life-threatening for weak elderly people in many cases. [0003] As a method capable of accurately evaluating and grasping swallowing disorders, swallowing contrast (Videofluoroscopic Examination of Swallowing (VF): VF) is most commonly used. However, VF is a test that has the possibility of swallowing, suffocation, etc., and attention is required. In addition, since an X-ray fluoroscopy...
