This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,709.

Summary of the Inventive Concept

An improved supraglottic airway device that incorporates innovative features to enhance patient safety, comfort, and reduce contamination risks, while improving airflow and ease of use for medical professionals.

Background and Problem Solved

The original supraglottic airway device patent, while providing a solution for maintaining an airway for patients, has inherent limitations related to airflow optimization, patient discomfort, and contamination risks. The new inventive concept addresses these limitations by introducing dynamically adjustable inner diameters, sensors to detect blockages, self-cleaning filters, detachable coupler assemblies, and intelligent monitoring systems.

Detailed Description of the Inventive Concept

The advanced supraglottic airway device features a breathing tube with a dynamically adjustable inner diameter, allowing for optimized airflow and minimized patient discomfort. A coupler assembly with a locking mechanism and pressure-sensitive release feature ensures secure connection and easy detachment. The device incorporates a sensor to detect potential blockages in the breathing tube, automatically triggering an alarm and a pressure release valve to prevent patient asphyxiation. A self-cleaning filter utilizing ultraviolet light sterilizes the airflow passage, while a side port with an automated suction control system minimizes the risk of patient discharge exposure. The detachable, disposable coupler assembly with a built-in, sterilizable airflow filter and the reusable breathing tube with an antimicrobial coating reduce contamination risks. The intelligent, real-time monitoring system tracks patient vital signs and alerts medical professionals to potential complications, while an integrated, automated suction control system optimizes patient care.

Novelty and Inventive Step

The new claims introduce novel features that improve the original supraglottic airway device, including dynamically adjustable inner diameters, sensors to detect blockages, self-cleaning filters, detachable coupler assemblies, and intelligent monitoring systems. These features provide a non-obvious solution to the inherent limitations of the original patent, enhancing patient safety, comfort, and reducing contamination risks.

Alternative Embodiments and Variations

Alternative embodiments of the advanced supraglottic airway device could include variations in the breathing tube material, coupler assembly design, and sensor types. Additionally, the device could be adapted for use in different medical settings, such as emergency response or pediatric care.

Potential Commercial Applications and Market

The advanced supraglottic airway device has significant commercial potential in the medical device industry, particularly in the areas of anesthesia, critical care, and emergency medicine. The device's enhanced safety features, improved airflow, and ease of use make it an attractive solution for medical professionals and hospitals seeking to improve patient outcomes and reduce healthcare costs.
