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. 11,857,727.

Summary of the Inventive Concept

The present inventive concept relates to a family of patient interface devices adapted for use in specific, challenging environments, including high-altitude, disaster relief, high-security, extreme weather, and remote, off-grid locations. These devices leverage the original double-Y supporting structure design to provide reliable, effective respiratory therapy in situations where standard devices may be inadequate.

Background and Problem Solved

The original patent disclosed a patient interface device with a frame assembly featuring a double-Y supporting structure. While this design has proven effective in general use cases, it may not be suitable for more extreme or specialized environments. The present inventive concept addresses this limitation by adapting the original design for specific niche applications, ensuring that users in these environments can still benefit from reliable respiratory therapy.

Detailed Description of the Inventive Concept

The inventive concept comprises a series of patient interface devices, each tailored to a particular environment or use case. For high-altitude environments, the device features a frame member with a double-Y supporting structure adapted to withstand increased air pressure, paired with a high-density, breathable cushion member. In disaster relief scenarios, the device is integrated with a portable oxygen generator powered by a rechargeable battery. For high-security environments, the frame member includes a tamper-evident feature, and the cushion member incorporates a biometric sensor for user identity verification. In extreme weather conditions, the device is coupled to a portable, weather-resistant respiratory therapy unit with a heating or cooling element to regulate gas temperature. Finally, for remote, off-grid locations, the device is designed for use with a portable, solar-powered respiratory therapy unit and features a cushion member with a built-in, rechargeable power source.

Novelty and Inventive Step

The present inventive concept introduces novel adaptations of the original double-Y supporting structure design to address the specific challenges of niche environments. The inventive step lies in the recognition of the need for specialized patient interface devices and the development of targeted solutions that combine the benefits of the original design with new features and materials tailored to these environments.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include variations in the materials used, the specific features incorporated, or the integration with other devices or systems. For example, the frame member could be constructed from lightweight, high-strength materials for use in aerospace applications or feature additional sensors or monitoring systems for enhanced user safety.

Potential Commercial Applications and Market

The present inventive concept has significant commercial potential in various industries, including healthcare, aerospace, disaster relief, and security. The market for specialized patient interface devices is substantial, with potential customers including hospitals, emergency responders, and military organizations. The devices could be marketed as standalone products or integrated into larger systems and platforms.
