Product description This oxygen mask is designed to deliver oxygen efficiently while improving comfort, visibility, and breathing stability. Key benefits — why you need it - Safer breathing: Inhaled oxygen comes directly from the suction/inlet tube into the mask while exhaled gas is routed out through a separate outlet. Inlet and outlet use different channels to reduce rebreathing of exhaled air. - Clear vision: A built‑in physical anti‑fog system prevents misting inside the mask, maintaining a clear view. - More comfortable wear: The adjustable elastic strap is designed not to pinch or catch hair, making the mask comfortable for extended use. - Smoother breathing: A double breathing hose circulates oxygen faster and more evenly than a single hose, promoting steadier respiration. - Broader field of view: The mask’s overall design increases the wearer’s peripheral visibility, providing a wider, clearer sightline. Key features and functions - Separate inhalation and exhalation channels: Direct oxygen delivery from the suction/inlet tube to the mask on inhalation; exhalation exits through a dedicated outlet. - Physical anti‑fog system: Prevents internal condensation and fogging without relying on coatings or consumables. - Adjustable elastic strap: Elastic, adjustable design that avoids pinching hair and improves user comfort. - Double breathing hose: Dual-line airflow for faster circulation and a more consistent breathing experience compared with single-hose designs. - Expanded viewing area: Mask geometry increases visible field to support monitoring, communication, and comfort. Practical applications - Home oxygen therapy: For patients receiving supplemental oxygen who need clear visibility and long‑term comfort. - Clinical and rehabilitation use: Suitable for therapy sessions or clinical care where reduced rebreathing and stable oxygen flow are important. - Mobility and monitoring situations: When users must remain alert and maintain a clear field of view during oxygen delivery. Performance and compatibility notes - Connects to oxygen or suction supply via the device’s inhalation tube; exhaled air is vented from a separate outlet to keep flow channels distinct. - Designed to improve breathing stability through dual‑hose circulation and to maintain a fog‑free viewing area with a built‑in physical anti‑fog system. - Adjustable strap accommodates different hair styles without pinching, increasing comfort during prolonged use. Materials and sizing - Contains an adjustable elastic strap and a dual breathing hose as integral components; mask shape is designed to widen the field of view. (No changes to supplied specifications or model functions are required for basic operation.) What this product delivers - Reduced rebreathing risk through separate flow channels - Clear, fog‑free visibility - Comfortable long‑term wear without hair pinching - Faster, more even oxygen circulation for smoother breathing - A wider, clearer field of view for the user
