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. 11,857,802.

Summary of the Inventive Concept

A novel intra-oral device for protecting oral tissues during radiation treatment, featuring improved tongue-deviating paddle geometry, real-time radiation exposure monitoring, and personalized customization for enhanced patient comfort and safety.

Background and Problem Solved

The original patent for an intra-oral device for protecting oral tissues during radiation treatment has limitations in terms of tongue positioning precision, patient discomfort, and radiation exposure monitoring. The new inventive concept addresses these limitations by introducing advanced features that enhance the overall efficacy and patient experience.

Detailed Description of the Inventive Concept

The advanced intra-oral radiation protection system comprises a dental arch assembly with an improved tongue-deviating paddle geometry, allowing for increased precision in tongue positioning and reduced discomfort for the patient. The system also features integrated sensors for monitoring radiation exposure and providing real-time feedback to the practitioner. Additionally, the system can be customized for individual patients using machine learning algorithms to predict optimal tongue positioning and generate a personalized tongue-deviating paddle design based on the patient's anatomy. The detachable and sterilizable tongue-deviating paddle ensures easy cleaning and reduces the risk of infection.

Novelty and Inventive Step

The new inventive concept introduces several novel features, including the improved tongue-deviating paddle geometry, real-time radiation exposure monitoring, and personalized customization, which are not obvious from the original patent. These advancements provide a significant improvement over the existing technology, enhancing patient safety and comfort during radiation treatment.

Alternative Embodiments and Variations

Alternative embodiments of the advanced intra-oral radiation protection system could include variations in the tongue-deviating paddle geometry, such as adjustable or modular designs, or the use of different materials for the paddle and dental arch assembly. Additionally, the system could be integrated with other radiation treatment technologies, such as imaging systems or treatment planning software, to further enhance its functionality.

Potential Commercial Applications and Market

The advanced intra-oral radiation protection system has significant commercial potential in the radiation oncology market, particularly in hospitals and cancer treatment centers. The system's ability to enhance patient safety and comfort during radiation treatment, while also providing real-time radiation exposure monitoring, makes it an attractive solution for healthcare providers seeking to improve treatment outcomes and reduce costs.
