The Uni-Flo2 Nasal Cannula is half the weight of a normal cannula and is designed to reduce skin contact by half. The cannula can be worn discretely on either side of the face and has a memory stabilization system that allows the tubing to be contoured to any face shape. Multiple strain relief points are included to reduce tube tugging and ensure the flow of oxygen. The one-sided design of the Uni-Flo2 looks good and makes it much less obvious that the individual is receiving supplemental oxygen. It delivers the same amount of oxygen but takes up half of the space with no cumbersome noose at the neck. The ergonomic design of the cannula itself fits securely inside the nostril, ensuring consistent oxygen flow both day and night. You will love the discrete, lightweight design of the Uni-Flo2.Uni-flo2 Cannula Features and BenefitsIncrease Dignity and ConfidenceExtremely Comfortable and LightweightVortex design increases oxygen uptakeMemory tube provides stable and comfortable fit for all patients50 percent less plastic, causes fewer soresDoes not constrict neck and throatLow profile designSingle-prong cannula reduces irritationReduces amount of medical-grade plastic that comes in contact with skinNo noose at neckDelivers oxygen at 1-6 LMPDelivers same amount of oxygen in half the spaceCan be worn on either side, interchangeable between nostrilsErgonomic design ensures ease of use and secures cannula in the nostrilCosmetically more appealing than two-prong cannulasNo need to remove to eat or drinkGuidance Stabilization Systems adjusts to all facial contoursMultiple strain relief points that allows for continuous flow day and nightProduct SpecificationsMaterials: Polyvinyl chloride (PVC)Non-sterileNo added phthalates (no added DEHP)
