Key Features of Silicone Four-Way Nasal Oxygen Cannula
Medical-Grade LSR Liquid Silicone
Made from materials that fully comply with medical device regulations and have passed ISO 10993 biocompatibility testing. Safe for extended contact with nasal mucosa—non-toxic, odorless, and skin-friendly.
Stable Four-Way Airflow Channel
Delivers balanced, uniform oxygen distribution. The corrugated anti-kink structure prevents tubing occlusion during wear, ensuring uninterrupted oxygen delivery in any sleeping position.
Seamless One-Piece Injection Molding
Zero assembly gaps eliminate air leakage risks. Comes with an attached anti-loss sealing plug for added clinical convenience and hassle-free operation.
Ergonomic Wearing System
Side fixation lugs allow easy headband attachment and tension adjustment. The pressure-dispersing design minimizes facial and nasal marks, enhancing patient comfort during long-term therapy.
Outstanding Resistance to Repeated Disinfection
Withstands high-temperature steam and alcohol-based disinfection. Maintains its flexibility, clarity, and odor-free property even after multiple sterilization cycles.
FAQ
What material is this Four-Way Nasal Oxygen Cannula made of?
This four-way nasal oxygen cannula is manufactured via an integral molding process using medical-grade liquid silicone rubber (LSR). It complies with both FDA regulations and ISO 10993 biocompatibility standards, and is specifically engineered for four-way nasal oxygen delivery systems.
What test reports can you offer for raw materials?
we provide a comprehensive documentation package including test reports (TDS, MSDS, COA, RoHS, REACH, and ISO 10993 biocompatibility) as well as regulatory compliance certificates (FDA). Additionally, we can arrange third-party laboratory testing upon your specific request.
Will the silicone become hard or cause nasal irritation after long-time wearing?
No，we utilize an anti-aging medical-grade liquid silicone formulation that maintains its softness and elasticity over extended use. The material has successfully passed ISO 10993 skin irritation and sensitization tests, ensuring it is gentle and non-irritating to the nasal mucosa, even during long-term wear.
Is this Nasal Oxygen Cannula reusable?
Yes, it’s reusable after proper sterilization. The silicone material resists deformation and yellowing after multiple cleanings.
What information do I need to provide for Nasal Oxygen Cannula ?
Please provide 2D and 3D drawings (stp,step or igs format) or actual samples, then our engineering team will provide DFM for your confirmation.
How long can I receive samples after confirming requirements?
For standard samples, the lead time is 3–5 working days after order confirmation. For customized samples requiring new mold development, it will take 10–15 working days following final drawing approval.
