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. 11,857,169.

Summary of the Inventive Concept

An advanced, collapsible fluid collection system for point-of-care diagnostics, featuring temperature control, fluid flow regulation, sample preparation, data tracking, and enhanced safety, thereby improving the efficiency, safety, and accuracy of diagnostic testing.

Background and Problem Solved

The original patent for a collapsible fluid collection system addressed the need for timely and accurate diagnostic testing, particularly in point-of-care settings. However, the original system had limitations in maintaining sample integrity, ensuring consistent fluid flow, and providing real-time data tracking. The new inventive concept addresses these limitations by integrating advanced features that improve the overall diagnostic testing process.

Detailed Description of the Inventive Concept

The enhanced collapsible fluid collection system comprises a temperature-controlled compartment to maintain a desired temperature of the collected fluid sample during transport and storage. The system also includes a collapsible container with an integrated fluid flow regulator to ensure consistent fluid flow rates during sample collection. Additionally, the system features a built-in sample preparation module, configured to prepare the collected sample for analysis, thereby reducing processing time and increasing testing efficiency. Furthermore, the system includes an integrated data tracking module, capable of recording and storing sample collection data, including date, time, location, and user identification. Finally, the system incorporates an enhanced safety feature, comprising a fluid containment membrane that prevents accidental spills or leakage of the collected fluid sample during transport and storage.

Novelty and Inventive Step

The new inventive concept introduces a novel combination of advanced features, including temperature control, fluid flow regulation, sample preparation, data tracking, and enhanced safety, which are not present in the original patent. These features provide a significant improvement in the efficiency, safety, and accuracy of diagnostic testing, thereby constituting a non-obvious and innovative solution.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include variations in the temperature control mechanism, such as using phase-change materials or thermoelectric cooling. Other variations could include different types of fluid flow regulators, such as pressure-controlled or vacuum-assisted regulators. Additionally, the sample preparation module could be adapted for specific types of diagnostic tests, such as PCR or ELISA.

Potential Commercial Applications and Market

The enhanced collapsible fluid collection system has significant commercial potential in the point-of-care diagnostics market, particularly in applications such as infectious disease testing, cancer diagnostics, and precision medicine. The system's advanced features and improved efficiency could appeal to healthcare providers, research institutions, and diagnostic companies seeking to improve the accuracy and speed of diagnostic testing.
