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. 11,857,713.

Summary of the Inventive Concept

Adaptations of automated peritoneal dialysis systems for specific, narrow markets or unique operational environments, such as high-altitude, disaster relief, high-security, extreme cold, and emergency response situations.

Background and Problem Solved

The original patent described an automated peritoneal dialysis system with a focus on adapting to patients' private lives and therapy needs. However, these systems may not be suitable for specific environments with unique challenges, such as high-altitude, disaster relief, high-security, extreme cold, and emergency response situations. The new inventive concept addresses these limitations by providing specialized variations of the automated peritoneal dialysis system tailored to these niche environments.

Detailed Description of the Inventive Concept

The new inventive concept encompasses a range of specialized automated peritoneal dialysis systems, each designed to operate effectively in a specific niche environment. For example, the high-altitude system features a portable APD machine adapted for low-oxygen environments and a specialized UF curve module for adjusting therapy based on altitude-related fluid shifts. The disaster-relief system includes a solar-powered APD machine and a remote prescription filtering module to prioritize regimens based on available resources. The high-security system incorporates an APD machine with biometric authentication and an encrypted data transfer module for secure prescription transfer. The extreme cold environment system features an insulated APD machine housing and a cold-resistant UF curve module for adjusting therapy based on temperature-related fluid shifts. The mobile peritoneal dialysis unit for emergency response includes a compact APD machine and a satellite-enabled prescription filtering module for remote regimen selection.

Novelty and Inventive Step

The new claims introduce novel and non-obvious adaptations of the automated peritoneal dialysis system to specific niche environments, which are not addressed in the original patent. These adaptations include specialized components, such as portable and solar-powered APD machines, biometric authentication, and encrypted data transfer, as well as tailored UF curve modules and prescription filtering modules.

Alternative Embodiments and Variations

Alternative embodiments of the specialized automated peritoneal dialysis systems could include additional features, such as real-time monitoring and remote software updates, or different form factors, such as wearable or implantable devices. Variations could also be developed for other niche environments, such as tropical or desert regions.

Potential Commercial Applications and Market

The specialized automated peritoneal dialysis systems have significant commercial potential in various industries, including healthcare, disaster relief, and emergency response. The high-altitude system could be marketed to patients living in mountainous regions, while the disaster-relief system could be deployed in disaster zones. The high-security system could be targeted at government agencies or high-risk individuals, and the extreme cold environment system could be marketed to patients living in Arctic or Antarctic regions. The mobile peritoneal dialysis unit for emergency response could be used by emergency responders and first responders.
