Summary of the Inventive Concept

An advanced mobile application-based mask sizing tool that leverages machine learning, 3D image analysis, and artificial intelligence to provide highly accurate and personalized patient interface size recommendations, improving respiratory treatment outcomes and user experience.

Background and Problem Solved

The original patent disclosed a mobile application-based mask sizing tool, which, although innovative, had limitations in terms of accuracy and adaptability. The present inventive concept addresses these limitations by introducing advanced technologies, such as machine learning and artificial intelligence, to improve the accuracy and efficiency of patient interface size selection.

Detailed Description of the Inventive Concept

The enhanced mask sizing tool comprises a mobile application that utilizes machine learning algorithms to analyze facial features from a user's selfie or 3D image, and provide a recommended patient interface size based on the analysis. The system can also capture video of a user's face, analyzing facial features and movements to select an optimal patient interface size, and provide real-time feedback to the user during the sizing process. Furthermore, the system can store analyzed facial features in a database for future reference, enabling continuous improvement of the recommended sizes over time. Additionally, the system can be integrated with respiratory treatment systems, adjusting pressure and humidity levels in real-time based on the user's facial features and breathing patterns, thereby optimizing the treatment for the user.

Novelty and Inventive Step

The new claims introduce the use of machine learning, 3D image analysis, and artificial intelligence to improve the accuracy and efficiency of patient interface size selection, which is not disclosed in the original patent. These advancements provide a significant improvement over the prior art, enabling highly accurate and personalized patient interface size recommendations.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include using different machine learning algorithms, incorporating additional data sources such as anthropometric measurements, or integrating with other medical devices to provide a more comprehensive respiratory treatment system. Variations of the system could also include using different types of image analysis, such as 2D or 3D image analysis, or incorporating additional features such as real-time feedback and guidance during the sizing process.

Potential Commercial Applications and Market

The enhanced mask sizing tool has significant commercial potential in the respiratory treatment industry, particularly in the areas of sleep apnea and chronic obstructive pulmonary disease (COPD) treatment. The system's ability to provide highly accurate and personalized patient interface size recommendations could improve treatment outcomes, increase patient comfort and compliance, and reduce healthcare costs. The market potential is substantial, with millions of patients worldwide requiring respiratory treatment.
