AECOPD lung sound digital biomarker acquisition device and method

The invention relates to an AECOPD lung sound digital biomarker acquisition device and method, and the acquisition device is provided with an acquisition unit which is used for acquiring lung sound generated by airflow friction of the lung of a patient in a continuous time period and storing the lung sound as a lung sound digital signal, the collection unit comprises a plurality of sound sensing elements arranged on the body surface of a patient according to a specific arrangement rule, the arrangement positions of the sound sensing elements are determined at least according to the positions of human bones related to the positions of the trachea and the bronchus, and the sound sensing elements can be divided into different collection groups based on the different arrangement positions of the sound sensing elements. The collecting method comprises the steps that lung sound generated by airflow friction of the lung of a patient is collected in a continuous time period, the lung sound is stored as a lung sound d
