Document Type and Number:
Japanese Patent JP2013543744
Kind Code:
A
Abstract:
A device for obtaining an equalization of a negative pressure in the middle ear is disclosed. The device comprises a facemask, an air pump and an air reservoir, all of them connected to a connecting tube. An increased air pressure is created by expiration into the facemask and/or by activating the air pump. A sufficient rise in air pressure in the device makes the air reservoir to expand, and this creates an increased pressure in the mouth/nose cavity and opens the Eustachian tube and forces air into the middle ear for equalization of the negative pressure in the middle ear.
