  • Patent number: 11246526
    Abstract: A swallowing diagnosis apparatus includes a controller which enables a first swallowing determination process of determining whether or not there is an aspiration risk in the swallowing on the basis of respiratory phases before and after a period in which swallowing has been estimated as having occurred; and a second swallowing determination process of extracting reference information including at least one of the sound information and the respiration information in a predetermined period including the period in which swallowing has been estimated as having occurred, obtaining a feature quantity from the extracted reference information, and performing a machine learning process on the obtained feature quantity to determine whether or not there is a possibility of dysphagia in the swallowing; and a display control process of causing a determination result obtained by the first swallowing determination process and a determination result obtained by the second swallowing determination process to be displayed.

  • Publication number: 20190125243
    Abstract: This swallowing training apparatus includes: a respiration detection part configured to detect a respiratory motion of a subject; and a controller. The controller is configured to: provide a trigger for swallowing induction to the subject on the basis of a detection result from the respiration detection part; detect that swallowing was performed by the subject; determine whether or not the detected swallowing was at an appropriate timing with respect to the respiratory motion; and output, to outside, information indicating a result of the determination.

  • Patent number: 9649062
    Abstract: A swallowing estimation device includes: a sound detection part configured to detect sound of a larynx portion; a respiration detection part configured to detect respiration; and a swallowing estimation part configured to estimate swallowing based on sound information outputted from the sound detection part and based on respiration information outputted from the respiration detection part. The swallowing estimation part obtains a value of a parameter for swallowing estimation with respect to a biological sound generation interval that corresponds to a respiratory cessation interval longer than or equal to 400 msec, and estimates whether swallowing has occurred in the biological sound generation interval based on whether the obtained value of the parameter satisfies a swallowing determination condition.

  • Patent number: 9440075
    Abstract: A swallowing assist device for assisting swallowing includes a respiration detection part, an application unit, and a control part. The respiration detection part detects respiration. The application unit is attached to a target section to apply a stimulus for facilitation of swallowing. The control part controls the application unit. The control part controls the application unit to start application of the stimulus to the target section during an expiration period detected according to a detection signal from the respiration detection part, and terminate the application of the stimulus to the target section during the expiration period.
