An ear-cleansing apparatus for removing wax plugs from the auditory canal includes a handgrip (6) which is provided with an operating valve and which is connected to a cleansing-water pressure-source via a hose (4), and which apparatus also includes a cannula (8) for insertion into an auditory canal. The pressure source consists in the water pressure of an existing water-supply system and the apparatus further includes a device (2) for reducing this pressure and maintaining the reduced pressure essentially constant. The device (2) is connected between the cannula (8) and a connection (1) to the existing water-supply system. The device (2) includes a safety valve (12) which is adjusted to the desired ear-cleansing pressure, and a throttle valve (15) which is connected upstream of the safety valve. |
