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. 11,857,499.

Summary of the Inventive Concept

An innovative pressure-regulating vial adaptor system that integrates vapour-containment and pressure-regulation modules to minimize vapour loss, optimize pressure regulation, and enhance user safety during fluid transfer.

Background and Problem Solved

The original patent disclosed a pressure-regulating vial adaptor, but it had limitations in terms of vapour containment and pressure regulation. The new inventive concept addresses these limitations by introducing a vapour-containment module and a pressure-sensing element that triggers a pressure-relief valve, ensuring improved safety and efficiency during fluid transfer.

Detailed Description of the Inventive Concept

The enhanced pressure-regulating vial adaptor system comprises a vapour-containment module integrated with a pressure-regulation module. The vapour-containment module is designed to minimize vapour loss during fluid transfer, while the pressure-regulation module features a pressure-sensing element that triggers a pressure-relief valve when a predetermined pressure threshold is exceeded. The system also includes a detachable vapour-containment cartridge that can be replaced with a new one after a predetermined number of uses to maintain optimal vapour containment. Additionally, the pressure-regulation module features a variable-flow orifice that can be adjusted to accommodate different fluid viscosities and flow rates. The system also includes a data-logging module that tracks pressure fluctuations and provides real-time feedback for optimizing pressure regulation.

Novelty and Inventive Step

The new claims introduce a vapour-containment module, a pressure-sensing element, a detachable vapour-containment cartridge, a variable-flow orifice, and a data-logging module, which are not present in the original patent. These features provide a significant improvement over the original patent, making the new inventive concept novel and non-obvious.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include different designs for the vapour-containment module, such as using alternative materials or geometries. The pressure-regulation module could also be implemented using different types of sensors or valves. Additionally, the system could be adapted for use with different types of medicinal vials or containers.

Potential Commercial Applications and Market

The enhanced pressure-regulating vial adaptor system has significant commercial potential in the pharmaceutical and healthcare industries, particularly in applications involving the transfer of sensitive or hazardous fluids. The system's improved safety and efficiency features make it an attractive solution for hospitals, clinics, and pharmaceutical manufacturers.
