Company History

The Uni-flo2 offers users much more freedom of movement than a dual prong cannula. Many hardly know they are wearing a cannula.


The development of the Uni-flo2 nasal cannula began as a quest by two of our founders, Dr. Hugh Payton and Mr. Campbell Cauthen.

They wanted to eliminate the problems they’d seen over many years of treating patients with respiratory diseases. Dr. Payton had retired from a 50-year practice in rural Ohio and Mr. Cauthen had worked as a Registered Respiratory Therapist for more than 30 years, treating patients who needed supplemental oxygen.

In their practices, they identified multiple problems with existing oxygen cannula devices. Numerous problems had not been addressed in any significant manner since the introduction of the dual prong cannula 68 years ago.  Considering the aging population and the increase in chronic obstructive pulmonary disease (COPD), Dr. Payton and Mr. Cauthen decided that now was the time to solve the dual cannula problems and improve the health of tens of thousands of patients needing supplemental oxygen while also increasing their self-esteem.

Three partners, Dr. Payton, Mr. Cauthen, and Mrs. Deborah Chadbourne, launched UPODS, LLC (unilateral patient oxygen delivery system) in 2013. A patent for their invention was granted in September 2016. It represented the first substantive improvement in the delivery of oxygen via nasal cannula in decades. FDA registration was also obtained that year. Manufacturing and distribution capability for the Uni-flo2 was achieved during 2016.  UPODS is now proud to offer the superior Uni-flo2 to patients, clinicians, and health care practitioners.
