Nasal rinse with valve actuatable by breathing air

Abstract

The nasal cavity washing device (10) of the present invention has a valve (32), a container part (12) and a cover part (24), wherein the container part (12) is used for containing the irrigation liquid (14) and is equipped with the cover part (24). The cap portion (24) has a nasal attachment (62) with an outflow opening (64) for irrigation fluid (14) in fluid communication with the interior (11) of the container portion (12) through an outflow channel (60) , wherein the nasal attachment (62) is defined for placement into one of the user's nostrils (70,92). According to the invention, the container part (12) or the cover part (24) is assigned a mouthpiece (44) for controlling the valve (32), which is closed in the rest position and thus prevents the flushing liquid (14 ) flows out through the nasal attachment (62), and the valve (32) can be placed in an open position by applying breathing air when the user blows breathing air into the mouthpiece (44), thereby allowing the irrigation fluid (14 ) out through the nasal attachment (62), wherein for outflow breathing air or ambient air flows into the container part (12).

Description

technical field [0001] The present invention relates to a nasal cavity washing device. Background technique [0002] KR20110056462A discloses a nasal rinse device which has a container part containing irrigating fluid and a tube section comprising a Venturi tube section for spraying irrigating fluid. The main body of the pipe section is bent in a C shape and the Venturi pipe section is integrally formed on the central lower end of the C-shaped pipe section in a T shape. Negative pressure is created when the user blows air into one end of the venturi segment whereby irrigation fluid is drawn from the container portion and sent through the segment to the user's nostrils to rinse the user's nose with irrigation fluid . [0003] The document EP2036527A1 discloses a nasal cavity rinser, which has an elastic container containing irrigation liquid, and the container has an irrigation port and a finger-closed vent. The vent is provided with a non-return valve which, in use, is op...

Problems solved by technology

In addition, the rinsing solution can also cause, for example, undesired gagging in the user when using known nasal rinsing devices.

[0004] In addition, it can also occur that the irrigation liquid is passively diverted or actively sucked into the larynx and lower respiratory tract by means of the known nasal irrigators, which can cause discomfort or even endanger the user in certain cases.
