AI Technical Summary
Existing breathing tubing cannot be flexibly shortened according to specific usage scenarios, is prone to tangling and knotting, increases airflow resistance, and is inconvenient to manage when moving patients or performing procedures, poses safety hazards, and occupies space.
A novel external wall heating breathing pipeline was designed, which uses a fixed component to adjust the length of the threaded tube through a telescopic cylinder and a rotating sleeve structure, and is equipped with a demisting component to reduce condensation, including an inclined baffle and a water guide channel structure to drain water droplets.
It enables flexible adjustment of the threaded tube length, avoiding tangling and blockage, reducing airflow resistance, improving safety and environmental cleanliness, and maintaining smooth airflow through the defogging component, thereby enhancing patient comfort.
