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. 11,857,453.

Summary of the Inventive Concept

A family of ostomy appliances adapted for use in high-security, disaster relief, extreme weather, high-altitude, and space exploration environments, providing improved safety, convenience, and performance in these unique settings.

Background and Problem Solved

The original patent disclosed an ostomy appliance with a non-circular flange for mechanical attachment of a bag or pouch. However, these appliances are not designed to meet the specific challenges of niche environments. The present inventive concept addresses the limitations of the original patent by providing specialized ostomy appliances tailored to the unique demands of high-security, disaster relief, extreme weather, high-altitude, and space exploration settings.

Detailed Description of the Inventive Concept

The present inventive concept encompasses a range of ostomy appliances, each designed to operate effectively in a specific niche environment. For high-security needs, the appliance features a tamper-evident flange and secure pouch attachment mechanism. In disaster relief settings, the appliance has a water-resistant coating and is paired with a drape material containing an integrated antimicrobial agent. For extreme weather conditions, the appliance incorporates a thermal insulation layer, while the high-altitude version features a pressure-resistant flange. Finally, the space exploration variant boasts a microgravity-compatible design. These adaptations enable users to maintain their ostomy care regimens even in the most challenging environments.

Novelty and Inventive Step

The new claims introduce novel features and combinations that distinguish them from the original patent. The inventive step lies in recognizing the need for specialized ostomy appliances in niche environments and designing solutions that address the unique challenges of each setting.

Alternative Embodiments and Variations

Alternative embodiments may include ostomy appliances with adjustable flanges for customizable security, or appliances with integrated sensors for monitoring environmental conditions. Variations could also include appliances designed for use in other niche environments, such as search and rescue operations or remote wilderness areas.

Potential Commercial Applications and Market

The present inventive concept has significant commercial potential in the medical device industry, particularly in the areas of ostomy care, wound management, and emergency response. Target markets may include government agencies, disaster relief organizations, and private companies operating in extreme environments.
