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. 11,857,774.

Summary of the Inventive Concept

This inventive concept leverages the core technology of the original intravenous tubing venting assembly to create adaptable air extraction systems for diverse industries, including aircraft cabins, urban areas, personal protective equipment, industrial machinery, and residential buildings.

Background and Problem Solved

The original patent addressed the issue of air bubbles in intravenous tubing, but its application was limited to the medical field. However, the problem of air bubbles and air quality persists in various industries, where it can have significant consequences. This inventive concept addresses these limitations by applying the core technology to new, high-impact areas.

Detailed Description of the Inventive Concept

The adaptable air extraction systems comprise a venting valve configured to allow air bubbles to escape while preventing fluid passage through the venting path, and a controller configured to regulate air flow and pressure. In the aircraft cabin application, the system monitors and controls air quality, ensuring a safe and healthy environment for passengers. In urban areas, the system reduces air pollution by deploying a network of air extraction devices in-line with ventilation systems. For personal protective equipment, the wearable device monitors and controls air quality, removing air bubbles and pollutants from the air supply. In industrial machinery, the system removes air bubbles from hydraulic fluid, improving equipment performance and longevity. Finally, in residential buildings, the system improves indoor air quality by removing pollutants and air bubbles from the air.

Novelty and Inventive Step

The new claims introduce novel applications and use cases for the core technology, demonstrating a non-obvious expansion of the original patent's scope. The inventive step lies in the adaptation of the air extraction technology to address distinct problems in diverse industries, leveraging the original patent's advantages while introducing new functionality and benefits.

Alternative Embodiments and Variations

Alternative embodiments may include variations in the venting valve design, controller configurations, and system integration approaches to accommodate specific industry requirements. Additionally, the use of advanced materials, sensors, and AI-powered control systems could further enhance the adaptable air extraction systems.

Potential Commercial Applications and Market

The adaptable air extraction systems have significant commercial potential across various industries, including aerospace, environmental remediation, personal protective equipment, industrial manufacturing, and residential construction. The market demand for innovative air quality solutions is growing, driven by increasing concerns about public health, environmental sustainability, and industrial efficiency.
