Title:
RESPIRATORY ACOUSTIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/093073
Kind Code:
A1
Abstract:
[Problem] To make it possible to make a respiratory acoustic device, which is for delivering vibrations artificially to the lungs and airways to fluidize mucus adhering to airways and promote the discharge of the same, easy to operate and make the device easy to transport. [Solution] A respiratory acoustic device 1 is provided with a housing 10 with a hollow 11, and a mouthpiece 20 with an air passage 21 that is in communication with the hollow 11. The housing 10 has a reflecting end 12 for reflecting air that has been blown in from the mouthpiece 20 and an open end 13 through which air that has been blown in from the mouthpiece 20 can escape. If a sudden exhalation such as a cough is blown into the housing 10 through the mouthpiece 20, the device causes the noise due to said exhalation to resonate with the oral and lower airway cavities, and vibrate the user's lungs and airways with the low frequency acoustic shock waves generated therein.
