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. 11,857,769.

Summary of the Inventive Concept

An improved drive assembly for a drug delivery system that enhances safety, efficiency, and environmental sustainability while reducing overall weight and waste.

Background and Problem Solved

The original patent's drive assembly, while effective, has limitations in terms of weight, material usage, and environmental impact. The new inventive concept addresses these limitations by introducing lightweight, high-strength materials, rechargeable batteries, and advanced sensors to prevent accidental air injection.

Detailed Description of the Inventive Concept

The enhanced drive assembly features a plunger member made of a lightweight, high-strength material, reducing the overall weight of the drive assembly. The drive assembly is powered by a rechargeable battery, minimizing waste and environmental impact. Additionally, the drive assembly includes a sensor to detect the presence of air in the container, preventing accidental injection of air into the patient. The plunger member also includes a built-in safety feature to prevent accidental activation of the drive assembly. Furthermore, the drive assembly features a quick-release mechanism for easy assembly and disassembly.

Novelty and Inventive Step

The new inventive concept introduces novel features such as the use of lightweight, high-strength materials, rechargeable batteries, advanced sensors, and built-in safety features, which are not present in the original patent. These features provide a significant improvement over the original drive assembly, enhancing safety, efficiency, and environmental sustainability.

Alternative Embodiments and Variations

Alternative embodiments of the enhanced drive assembly could include different materials, geometries, or actuation mechanisms. For example, the plunger member could be made of a composite material, or the drive assembly could be powered by a different type of energy source, such as a spring or a motor.

Potential Commercial Applications and Market

The enhanced drive assembly has significant commercial potential in the medical device industry, particularly in the field of drug delivery systems. The improved safety, efficiency, and environmental sustainability features make it an attractive solution for pharmaceutical companies, hospitals, and patients.
