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. 11,857,723.

Summary of the Inventive Concept

The inventive concept enhances the original air delivery device by optimizing airflow efficiency through real-time sensor feedback, adaptive impeller speed adjustment, and user feedback, resulting in improved patient outcomes.

Background and Problem Solved

The original patent disclosed a device for delivering air to a patient, comprising a first portion with a sensor and a second portion with an impeller and outlet. However, the original device had limitations in terms of airflow efficiency, impeller speed adjustment, and user feedback. The new inventive concept addresses these limitations by introducing real-time sensor feedback, adaptive impeller speed adjustment, and user feedback to optimize air delivery efficiency.

Detailed Description of the Inventive Concept

The new inventive concept consists of a device with a first portion having a first airflow inlet and a sensor, and a second portion having a second airflow inlet, an impeller, and an outlet. The sensor is configured to sense airflow and adjust the impeller speed in real-time to optimize air delivery efficiency. The device is further configured to provide real-time feedback to the user on the air delivery efficiency. Additionally, the device can adapt to changes in the patient's respiratory rate and adjust the impeller speed accordingly. This results in improved air delivery efficiency, reduced energy consumption, and enhanced patient safety.

Novelty and Inventive Step

The new inventive concept introduces the following novel and non-obvious features: real-time sensor feedback, adaptive impeller speed adjustment, and user feedback. These features are not present in the original patent and provide a significant improvement in air delivery efficiency.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept may include different sensor types, such as pressure sensors or flow sensors, and different impeller designs, such as axial or centrifugal impellers. Additionally, the device may be integrated with other medical devices, such as ventilators or oxygen concentrators, to provide a comprehensive air delivery system.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in the medical device industry, particularly in the areas of cardiopulmonary resuscitation, ventilation, and oxygen therapy. The device can be marketed to hospitals, emergency medical services, and home healthcare providers, with potential applications in both developed and developing markets.
