Nasal douche device

Chronic nasal symptoms such as rhinosinusitis can result in sufferers experiencing congestion, facial pain, and headaches. The mucous membrane that lines the paranasal sinuses frequently becomes inflamed, and remedies to resolve such discomfort range from using decongestant nasal sprays, ingesting antibiotics, and in extreme cases, even surgery. A non-medicated option that is gaining attention is nasal irrigation. This process, which is also termed nasal lavage or nasal douche, attempts to flush out excess mucus and debris from the nose and sinuses in an attempt to avoid and remove infection.

The concept of nasal irrigation is ancient and in its most basic sense, can be achieved by snorting water from a cupped hand. More recently, equipment has been designed to improve the quality of nasal flushing and to alleviate discomfort caused by such a process. Perhaps the best known product is the ceramic or neti-pot which requires the user to insert a type of teapot spout into one nostril and aided by gravity, stream water through the nasal passage. Automatic and electrically powered systems are also available remove comma and and which pulsate water at the push of a button.

In all cases salt, baking soda and warm water are used to help dislodge mucus and debris. The University of Wisconsin's Department of Family Medicine conducted clinical studies on the efficacy of nasal irrigation, and following their results, provide instruction on how to achieve best results from such a process. They suggest that a ratio of between 0.9% to 3% saline solution should be used in water heated to room temperature. It is with this data that it becomes evident that existing nasal irrigation systems lack user-centric designs.

The nasal douche featured on this page builds on these existing designs, but focuses more on the process of irrigation. In particular, it attempts to simplify and speed up the preparation phase. It makes use of a bellows styled mechanism to dispense a salt and baking soda mixture comma and air into a water chamber. In doing so, it effectively forces a pulsating stream of saline solution out of the top of the device. The images below provide further information on how the device is actually used, and the images should be read from left to right.


The device’s water chamber is removed and filled with water. Stepped level indicators assist the user to estimate the quantity of water and degree of flushing that is required for their purposes. The filled chamber is refitted to the device, and a seal arrangement prevents any leakage.


The device provides an internal and refillable chamber for the salt/baking soda mixture (a weeks supply). The user dispenses a choice of three volumes of this mixture by rotating the mid-collar. The product is then shaken, and inserted into a cradle which heats it to 23 Deg C.


The cradle sounds to indicate that the mixture is ready. The user removes the product from the cradle, and squeezes the top half (bellows section) to channel the mixture into each of their nasal passages. The mechanism allows the user complete control of flow pressure and duration.
