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. 11,857,646.

Summary of the Inventive Concept

Improved methods and systems for preparing phospholipid-based ultrasound contrast agents adapted for specialized applications, such as high-security environments, disaster relief, extreme weather conditions, remote areas, and areas with limited access to clean water.

Background and Problem Solved

The original patent disclosed improved methods for preparing phospholipid-based ultrasound contrast agents, but these methods have limitations when applied to specific, narrow market or unique operational environments. The new inventive concept addresses these limitations by providing specialized variations and niche solutions for preparing phospholipid-based ultrasound contrast agents in challenging environments.

Detailed Description of the Inventive Concept

The new inventive concept comprises a system for preparing phospholipid-based ultrasound contrast agents in high-security environments, featuring a secure, tamper-evident container for storing divalent metal cations, and a phospholipid solution formulation that is resistant to precipitation induced by said cations. Additionally, the concept includes a method for preparing lipid-encapsulated gas microspheres in disaster relief situations, utilizing a portable, battery-powered mixing device and a phospholipid blend that is tolerant of varying temperatures and humidity levels. Furthermore, the concept encompasses a phospholipid-based ultrasound contrast agent formulation for use in extreme weather conditions, comprising a combination of DPPA, DPPC, and MPEG5000-DPPE, and a stabilizing agent that prevents precipitation of the phospholipids in the presence of divalent metal cations. The concept also includes a system for preparing phospholipid-based ultrasound contrast agents in remote or resource-limited areas, featuring a compact, self-contained manufacturing unit that includes a phospholipid solution formulation and a means for filtering out precipitated phospholipids. Finally, the concept includes a method for preparing lipid-encapsulated gas microspheres in areas with limited access to clean water, utilizing a phospholipid blend that is resistant to contamination by heavy metals and other impurities.

Novelty and Inventive Step

The new inventive concept is novel and non-obvious compared to the original patent, as it provides specialized variations and niche solutions for preparing phospholipid-based ultrasound contrast agents in challenging environments, which were not addressed in the original patent. The inventive step lies in the adaptation of the original methods to specific, narrow market or unique operational environments, resulting in improved performance, stability, and safety in these environments.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include the use of different phospholipid blends, stabilizing agents, or manufacturing units adapted for specific environments. Variations could also include the integration of additional features, such as sensors for monitoring environmental conditions or automated systems for preparing the phospholipid solution formulations.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in various industries, including medical imaging, disaster relief, and environmental monitoring. The target markets include high-security facilities, disaster relief organizations, and remote or resource-limited areas, where the specialized variations and niche solutions provided by the inventive concept can address specific needs and challenges.
