NoMoRa: Comfort for Oxygen Therapy Patients

Invented by Theresa Carr of Colorado Springs, Colorado

Millions of people depend on oxygen therapy every day, but for many, the nasal cannula that keeps them breathing comfortably also causes real pain. The hard plastic and material used in standard cannulas can rub against sensitive skin, leading to rashes, sores, and raw, irritated skin right under the nose. The discomfort and embarrassment are so severe that some patients remove their cannula altogether — putting their health at risk.

For Theresa Carr of Colorado Springs, Colorado, this was not a minor inconvenience. Theresa is allergic to the material used in standard cannulas, and when she asked her care providers for something to protect her skin, she was told nothing like that existed. So she started experimenting on her own.

She tried creams and ointments — they didn't help. She tried a band-aid — uncomfortable and impractical. She tried a piece of cloth, but it wouldn't stay in place. Then she found a small piece of adhesive cloth material she wasn't allergic to, shaped it into a simple cover, and slid it onto the cannula. Within two weeks, the rash was gone and her skin had healed completely.

  • Slides On Instantly. Fits any standard nasal cannula in seconds.
  • Hypoallergenic. Soft material formulated to prevent rash and irritation.
  • Made for Daily Wear. A low-profile design built for extended, everyday use.
  • No Creams. No Adhesives. Just a soothing barrier between the tubing and the skin.
  • Patent Protected. Covered by U.S. Design Patent No. D1,098,412.

The result is NoMoRa — short for No More Rash. It's a soft, hypoallergenic cover that slides directly onto the cannula tubing, forming a gentle barrier between sensitive skin and irritating plastic before irritation can start. Patients can finally enjoy true comfort, even if they need oxygen support every day.

Theresa has been making NoMoRa covers herself ever since, because nothing on the market did what her simple invention does. Now patent protected, she's ready to bring NoMoRa to the oxygen therapy patients and caregivers who need it. Ready to learn more?
