AI Technical Summary
Existing respiratory support systems face inefficiencies when one nare of a user becomes occluded, leading to reduced effectiveness of respiratory therapy, and there is a need for a system that can adapt to such conditions by redirecting airflow effectively.
A dual outlet blower with a centrifugal impeller that rotates in opposite directions to direct airflow through different nasal outlets or a combination of nasal and oral outlets, controlled by a sensing arrangement and motor to ensure optimal airflow distribution based on nare occlusion or user preference.
The system ensures continuous and effective respiratory support by automatically redirecting airflow to unoccluded nares or oral outlets, maintaining therapy efficacy even when one nare is blocked, and allowing for user preferences in breathing mode.
