Abstract: The Respiratory Interface Device is a novel, mouth-inserted airway management tool designed to facilitate both oxygen delivery and carbon dioxide sampling through an integrated oral pathway. Unlike conventional nasal cannulas or oropharyngeal airways, this device features internal channels configured to house standard or capnography-compatible tubing, allowing simultaneous gas delivery and exhaled gas monitoring. The device includes a contoured dental plate and an airway arch that conforms to the patient's hard palate, maintaining upper airway patency while avoiding stimulation of the protective airway reflex. Its ergonomic design supports a secure oral fit and provides a streamlined interface for procedural sedation, monitored anesthesia care, emergency airway support, and alternative oxygenation strategies in patients where nasal access is limited or contraindicated. The Respiratory Interface Device represents a versatile, dual-function solution for enhanced airway management and respiratory monitoring.
