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.
Claims16
A device for obtaining an equalization of a negative pressure in the middle ear of a human being, having a face with a nose and a mouth, wherein the device comprises:
- a facemask (1), which facemask (1) is adapted to tightly cover at least the nose and mouth, thereby creating an air chamber between the face and the facemask, and which facemask has a facemask air channel (2) which allows air to flow in or out of the air chamber,
- an air source (5), having the capacity to deliver an increased air pressure compared to the atmospheric air pressure through an air source outlet (13),
- an air reservoir (7), having a reservoir air channel (8) which allows air to flow in or out of the air reservoir (7), which air reservoir (7) is designed to define and maintain an air pressure exceeding the atmospheric pressure and work like a pressure regulator when loaded,
- and a tube structure (3), having an interior and at least three openings (14, 15, 16) adapted for connecting the facemask air channel (2), the air source outlet (13) and the reservoir air channel (8) to the tube structure interior.
