An apparatus for acquiring swallowing-related information includes an ultrasound transmitting device that transmits ultrasound waves to a larynx and/or trachea area of a subject, an ultrasound receiving device that converts the ultrasound waves transmitted through the larynx and/or trachea area of the subject to received signals, an attachment device that holds the ultrasound transmitting device and the receiving device on the neck of the subject such that the ultrasound waves pass through the larynx and/or trachea area of the subject, a processing device including circuitry that coverts the received signals into swallowing-related information, detects at least one swallowing-related event and biological information based on the swallowing-related information, analyzes at least one swallowing-related event and the biological information to generate swallowing-related information analysis, and generates information for safety and dysphagia rehabilitation based on the swallowing-related information analysis including an alert system activation that activates alert system to inform aspiration of the subject. The swallowing-related event includes at least one selected from the group consisting of dysphasia, abnormal swallowing, and cough, and the biological information includes at least one selected from the group consisting of body temperature, pulse rate, respiration rate, blood pressure, mastication-related information, vocalization, and movement of the neck.Linvention porte sur un appareil dacquisition dinformations relatives à la déglutition comprenant un dispositif démission dultrasons qui émet des ondes ultrasonores à une zone de larynx et/ou de trachée dun sujet, un dispositif de réception dultrasons qui convertit les ondes ultrasonores émises à travers la zone du larynx et/ou de la trachée du sujet en signaux reçus, un dispositif de fixation qui maintient le dispositif démission dultrasons et le dispositif de réception sur le cou du sujet de telle sorte que les
