Nasal Prongs | Manufacture Medical Oxygen Nose Prong Cannula

Nasal Prongs

Nasal prongs are well known as nasal cannula, it is a hollow soft short transparent tube with two tubes/tips that will be inserted into people’s nostril to transfer/deliver oxygen from oxygen device to people. Nasal piece should be soft and comfortable for user, the nose piece directly contact to nose skin and cannot hurt nostril, both soft plastic and liquid silicone can be used, considered safety and comfort, liquid silicone is mainly used for manufacturing nasal cannula. By using liquid silicone (LSR) injection molding (LIM), nasal cannula has four features: very soft and flexible, easy to adapt to user’s philtrum and nostril; high transparent, looks like crystal/glass, won’t affect user’s sighting; strong tensile and durable (for health and cleaning, users should change/replace his nose cannula every 72-96 hours); smooth surface, easy to clean or sterilize (liquid silicone is resistant to high temperature sanitizing).

Nasal Prongs - How To Guarantee High Quality?

Nasal cannula tips are made from medical silicone by injection molding, in order to have great wearing feeling for users, the nose tips should be smooth, flexible, and odorless. Liquid silicone injection molding tools of nasal tubes with ejection design and mold cores, the place that tools closed together will have a joint line, also called parting line, firstly the parting line should be as small as possible, try best to get cannula surface smooth feeling, no sharp edges, no extra flash. The difficulty of silicone nasal cannula is how to control burrs on holes edges of the two small tips/prongs. For avoiding potential breathing risk, burrs-free is important.

What is burrs or flash on silicone nasal prongs? Burrs look like extra silicone material that left on product edges and not easy to remove.
