Science behind the NasalCare Nasal Rinse Kit

Science behind the NasalCare Nasal Rinse Kit

      Our first design was a squeeze bottle, very similar to the one on the market. Yes, it was better than neti pots, but after squeezed, the bottle became negatively pressured and sucked the nasal solution back into the bottle and narrow, hard-to-clean tube. We saw the risk of re-infection. We also knew that time-consuming wash after use would not be practical if users need to frequently rinse their noses. And if patients did not wash the contaminated tube and bottle well, there would be a high risk of sinus re-infection even though their doctors had performed excellent nasal surgeries. This was proved by Dr. Amin Javer’s group from St. Paul's Hospital, Vancouver, Canada, who orally presented their clinical studies on the first day of the Rhinology World 2009 conference in Philadelphia (Abstract #1356 on page 47 of the Program).

    To prevent the problematic backflow, we invented a nasal irrigator with two one-way valves. We filedour patents in 1997 and 1998 and both were granted in 2000 (Over two years earlier than NeilMed’s). We filed 510K application to FDA and received clearance in 2002. We spent a lot of time to perfect the design so the irrigator would be able to efficiently remove tough bacterial biofilm and dried debris without causing discomfort. The speed of liquid flow and the strength of pressure are easily controlled by the two valves through user’s hands, which a squeeze bottle without the valves can hardly achieve. Hindered by negative pressure crushing the bottle, inefficient “hose,” and too soft bottle, the cleansing efficiency of the backflow-prone bottle is obviously lower than that of the dual-vale nasal irrigator.

      As stated in our first business plan in 1998, “As we believe all people will need our product for nasal rinse to prevent and treat upper respiratory diseases, the final product must be user-friendly, extremely safe, and cost-effective, akin to tooth brushing.” Our current NasalCare product is the second generation; it has overcome all of the drawbacks of neti pots, backflow-prone squirt bottles, and electric irrigators. To make it easier for users’ to add the pre-mix powder and water, we re-designed the bottle to have a wider opening. We also added a dust-preventive lid for better hygiene and convenient for travelers. We specifically chose plastic that does not easily absorb medicine because doctors sometimes prescribe the product for drug delivery.

      We found that hypertonic saline was more effective than isotonic saline for chronic sinusitis, but the former caused stinging, burning and dryness. So we improved the saline by changing regular salt tomineral-rich sea salt-which has less sodium. Besides sodium bicarbonate, we also included aloe extract for its moisturizing and potential anti-inflammation and anti-microbe activities, and buffering citric acid/sodium citrate for more comfort and helps stimulating natural mucosal secretions to further protect the nasal membranes.

      The backflow-prone squirt bottle is troublesome. Cleaning the narrow tube and bottle requires a 6-step regimen as shown in their instruction. A biweekly change to a new bottle would 1) Add 10 foldsmore cost to consumers than the cost of NasalCare (guaranteed for one year), 2) Environment-unfriendly; create more trash, and 3) Waste of energy and natural resources; consume more plastic for bottle and drinking water for cleaning the bottle.

       Our product provides solutions and we hope you become involved in our efforts and to introduce the state of the art nasal irrigation system to your patients. You can count on our excellent services support.


Why the NasalCare® can help reduce spread of the A/H1N1 virus?

     NasalCare can wash out viruses, not just bacteria as shown in our studies, so to protect people from flu virus infection. Since viruses are too small, mask cannot filter them, flu drugs most likely does not work well and even it were effective, the virus may quickly develop resistance.

     As you know, the first and primary place for flu virus to infect victims is the nose, and according to the CDC, it takes 24 hours to 4 days of the incubation period of virus shedding into nasal secretions. This indicates that the attention in management of the virus infection and spread should be on the nasal cavities. Washing hands is not enough and in fact the virus-contaminated hands actually make people sick through the nose, little via the month.

     Therefore, timely elimination of the viruses from nasal cavities shall significantly reduce the risk of developing colds and flu. With expertise in infectious diseases and epidemiology, I believe daily nasal irrigation using the NasalCare Nasal Rinse Kit is a simple, safe, comfortable, inexpensive and effective approach in fighting flu virus infections. This has been proven by recent clinical studies: Daily nasal rinse prevents common cold in adults and school children, and also reduces severity of symptoms and shorten the duration of illness (1-2). Washing the virus down to the drain not only protect the users but also help protect people around them and reduce the spread because the less viruses in the aerosol, droplet, and secretions when people sneeze or cough.

     Remember, not all nasal rinse devices are created equal. The NasalCare device is the only one that has anti-backflow feature and with dust preventive cover. The backflow-prone squirt bottle and hard to clean Neti pots cannot do the job because the nasal viruses will contaminate the pot, narrow tube and bottle, and lead to re-infection with viruses and bacteria.

Cleans, Moisturizes, Soothes and Protects Your Nose™
Effective in Prevention and Treatment of Respiratory Disorders

     Upper respiratory disease (including sinusitis, flu and colds, environmental asthma and related conditions) has become America's first environmental epidemic, with nearly one-third of Americans suffer from allergic sinusitis, rhinosinusitis, the most common chronic disease in the United States. Those conditions account for millions of physician visits yearly, accounting for billions in health care costs. Nasal and sinus complaints are the most common causes for people to consult physicians. Most treatments like decongestants, nasal sprays and pain relievers only treat the symptoms. In contrast, the FDA registered NasalCare™ Nasal Rinse System works by removing the source of the irritants. In fact, nasal irrigation is recommended for rhinosinusitis by the American Academy of Family Physicians, and many other medical associations in North America, Europe and Asia. This innovative product has helped many patients who suffered from nasal allergies, and sinus problems and tried everything but failed.


     Nasal Irrigation Methods:

     There are different techniques to do this: flushing each nostril by using high capacity syringes, purchasing a special cup (neti pot) or simply rinsing by hand. However, these traditional methods have several limitations:


·          Not easy to perform: they require experience to be used properly and are uncomfortable to do.

·          Not effective: insufficient irrigation.

·          Risk to spread infection to the middle ear: because of the head position and the uncontrolled pressure.


     The most convenient way to perform effective and safe nasal irrigation is using NasalCare Nasal Rinse Kit. This system allows easy irrigation of both nose and sinuses with a sufficient volume (8 oz) in two minutes. In addition, the unit produces continue flow that greatly increases the mechanical effect of these washes.


     The current available irrigation devices are presented in the following table for comparison with our NasalCare™ System.

What makes NasalCare™ unique?

      NasalCare™ Sinus Rinse System is patent-protected, clinically proven, and FDA approved over-the-counter product. It consists a nasal irrigator and 30 packets of nasal rinse mix.

      The Patented, Unique Nasal Irrigator:

      It is developed based on the patented technology which can prevent sinus re-infection by the exclusive anti-backflow feature and enabledeep cleaning of sinus cavities that traditional Neti pots and squeezable bottles can hardly reach.

     The irrigator is composed of 9 parts. The smart design allows you keep your head upright during washing. The one-way liquid valve permits the fluid to flow only from the suction tube into the nostril but not back to the bottle, preventing contamination of the solution and bottle. The one-way air valve allows air to flow into the bottle to prevent negative pressure in the bottle which allows continue nasal irrigation. The flow speed of the liquid is easily controlled by the user’s hand. All those futures together create continual solution flow along the nasal floor and cleanse nasal and sinus passages more effectively, user-friendly, comfortable, simpler,and therefore more adoptable than using neti pots or other nasal rinse products. More over it opens up congested sinuses by drawing out mucus and debris.

      The Patented, Unique Nasal Rinse Mix

     This patented nasal rinse mix is much better than regular saline. It is scientifically formulated with special sea salt, sodium citrate, sodium bicarbonate and aloe vera extract. Each packet makes one bottle of washing solution (8 oz). This unique solution not only ensures maximum comfort during the washing process but also provides a very pleasant, soothing, moistening, and fresh sensation. It does not cause any stinging or burning like most of other products do. The system makes the nasal irrigation simple, easy, neat, comfortable, and relaxing.
