Document Type and Number:
Japanese Patent JP2002519150
Kind Code:
A
Abstract:
An apparatus for treatment of Ménière's disease by intermittently increasing air (gas) pressure, in an air (gas) pressure chamber in communication with an outwardly sealed external ear volume bordering the tympanic membrane, comprises a peripherally fixed flexible circular diaphragm forming a wall of the chamber and being displaceable in a perpendicular direction essentially without being tensioned. Displacement of the diaphragm away from the chamber is effected by air pressure built up in the chamber, not by a separate displacement device. The apparatus further comprises a linear electromagnetic device for displacing the diaphragm. The apparatus may include systems for gas pressure sensing; chamber pressure equalizing; and microprocessor control, for controlling the displacement of the diaphragm and the pressure equalizing device by a signal input from the pressure sensing device.
