Abstract
A nasal lavage device having a reservoir configured to hold a quantity of lavage solution. A spout is coupled to the reservoir operates to conduct the lavage solution from the reservoir to a spout end. The lavage system comprises alone or in combination an interchangeable tip assembly and a check valve mechanism. The tip assembly detachably couples to the spout end and is configured to fit in contact with a user's nose so as to enable lavage solution to be conducted from the reservoir, through the spout, through the tip to the user's nose. The check valve is located between the reservoir and the tip and operable to inhibit fluid backflow from the tip to the reservoir.
Claims24
A nasal lavage device comprising:
- a reservoir configured to hold a quantity of lavage solution;
- a spout coupled to the reservoir and operable to conduct the lavage solution from the reservoir to a spout end;
- and
- a tip assembly detachably coupled to the spout end and configured to fit in contact with a user's nose so as to enable lavage solution to be conducted from the reservoir, through the spout, through the tip to the user's nose.
A method for performing nasal lavage comprising:
- filling a reservoir with a lavage solution;
- attaching an interchangeable tip to the reservoir;
- sealing the tip against a nose;
- and
- conducting the lavage solution from the reservoir through the tip to the nose.
A nasal lavage device comprising:
- a reservoir configured to hold a quantity of lavage solution;
- a spout coupled to the reservoir and operable to conduct the lavage solution from the reservoir to a spout end;
- a check valve located between the reservoir and the tip and operable to inhibit fluid flow from the tip to the reservoir;
- and
- a tip at the spout end and configured to fit in contact with a user's nose so as to enable lavage solution to be conducted from the reservoir, through the spout, through the tip to the user's nose.
An interchangeable nasal lavage tip comprising:
- an exterior sealing surface for creating a seal to a user's nostril;
- a channel formed in the tip and operable to conduct fluid into the user's nostril;
- an attachment mechanism located at one end and operable to removable attach the tip to a reservoir of lavage fluid.
A disposable nasal lavage system comprising:
- a disposable reservoir operable to hold a quantity of lavage solution;
- a tip coupled to the reservoir having a channel formed therein and operable to conduct fluid into the user's nostril from the reservoir;
- a venting mechanism in the reservoir and operable to release vacuum created by dispensing the lavage solution from the tip.
