Closed-Loop Nasal Rinse Kit with Collection Bottle

Rinsing the nose with a squeeze bottle or neti pot is messy: the solution runs out of the other nostril, down the face and into the sink. This kit closes the loop. A soft blister hood with a silicone seal sits over the nose, held by an elastic strap. A syringe pushes rinse solution through a hose to a sponge-ball plug in one nostril. The used solution collects in the hood and is drawn off through a second tube into a capped bottle by a squeeze bulb with a one-way valve.

The problem

Nasal rinsing with saline is widely used in nasal care, but the usual tools - squeeze bottles, neti pots and spray devices - send the used solution out of the other nostril and the mouth, onto the face and into the sink. The patent describes conventional nasal cleaning devices as messy and hard to collect from, and says traditional methods can leave the nose uncomfortable. Care settings in particular need a cleaner way to collect the used solution.

The solution

The patent encloses the rinse in a sealed hood and collects the outflow:

  1. A soft hood (1) - a blister with an air hole on top - goes over the nose. A silicone seal (2) lines its edge and an elastic strap (4) holds it on.
  2. Inside the hood, a first hose (6) ends in a sponge-ball nose plug (7). An inlet tube (5) through the hood wall connects it, via a second hose (9), to a syringe (11) of rinse solution.
  3. A water baffle (3) at the bottom of the hood stops the solution from spilling.
  4. An outlet tube (12) leads from the hood to a capped collection bottle (16).
  5. A squeeze bulb (17) with a one-way valve (18) creates suction in the bottle, drawing the used solution out of the hood.

According to the patent, the device is designed to keep the rinse solution contained and collected, rather than letting it spread during cleaning.

  2. Fit the hood over the nose with the strap; the sponge-ball plug sits at the nostril.
  3. Push the syringe slowly to rinse.
  4. Squeeze the bulb to draw the used solution from the hood into the bottle.
  5. Empty and clean the bottle and parts after use.

Applications

Home nasal care

A cleaner way to rinse at home without leaning over a sink.

Care homes and home-care nursing

Caregivers rinsing for someone in a chair or bed, with the used solution collected.

Clinics

Nasal rinsing in treatment rooms where splashing should be avoided.

Travel kits

A sealed system for rinsing in hotel rooms.

Where it is less suitable

  • Very young children - hood sizes, flows and any pediatric use must be designed and cleared specifically.
  • Medical treatment claims - the product should not be marketed to treat disease unless cleared by the FDA for that use.

Frequently asked questions

How is this different from a squeeze bottle or neti pot?

According to the patent, the rinse happens inside a sealed hood over the nose: a syringe feeds solution through a sponge-ball plug, and the used solution is drawn into a capped bottle instead of running out over the face and into the sink.

What does the squeeze bulb do?

It creates suction in the collection bottle. A one-way valve on the bulb lets air out, so each squeeze draws the used solution from the hood through the outlet tube.

What solution is used?

The patent does not specify a solution. Saline rinses should be made with distilled, sterile or previously boiled water, as the FDA advises; we include this in the instructions.

Can someone else operate it for the user?

Yes - the hood is strapped on and the syringe and bulb are outside, so a caregiver can operate them. This suits care settings.

Is it a medical device?

In the US, nasal irrigation devices are regulated by the FDA. The brand owner confirms the classification and any clearance; we manufacture to the required quality system.

Can the parts be reused?

Hood, bottle and bulb can be designed for cleaning and reuse, with single-use nose tips, or as a fully disposable kit for clinics.

Can this design be made and sold in the US?

The patent was filed only in China, so it does not restrict the design in the US. It is in force in China until July 2027 at most, and making or selling it there needs the owner’s permission. Nasal irrigation devices may be covered by other patents - see Patent & Production - so we recommend a freedom-to-operate check before volume production.

Are you affiliated with the patent owner?

No. IP2M is an independent design and manufacturing service working from the public patent document.
