Breathing mouthpiece, reusable

A reusable breathing mouthpiece is a small, rigid or semi-rigid device inserted between a patient’s lips to create a gastight seal, enabling access to the respiratory tract. It connects directly or via adapters to respiratory tools like ventilators, inhalers, or spirometers, ensuring proper airflow for diagnostics or therapy—sometimes even producing a whistling sound to aid inhalation technique.

These devices are typically classified based on their intended use and risk level, with regulations varying by jurisdiction. They may be supplied as standalone products or as part of a larger respiratory system, and their reuse requires strict cleaning and maintenance protocols to ensure patient safety and device integrity.
