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. 11,857,497.

Summary of the Inventive Concept

This inventive concept presents a series of direct improvements and enhancements to the original fluid transfer station in a robotic pharmaceutical preparation system, focusing on efficient, accurate, and safe fluid transfer.

Background and Problem Solved

The original patent, 'Fluid transfer station in a robotic pharmaceutical preparation system', addressed the need for efficient fluid transfer in pharmaceutical preparation. However, it had limitations in terms of alignment, flow rate control, and contamination risk. The new inventive concept tackles these limitations by introducing advanced sensors, real-time monitoring, and self-cleaning mechanisms.

Detailed Description of the Inventive Concept

The enhanced fluid transfer station comprises a container-septum alignment sensor to detect and adjust the alignment of the container-septum and fluid transfer connector septum for efficient fluid transfer. Additionally, a manipulator with a built-in fluid flow rate sensor monitors and controls the fluid transfer rate in real-time, ensuring accurate and efficient fluid transfer. A self-cleaning mechanism for the container-septum and fluid transfer connector septum reduces the risk of contamination and improves system reliability. Furthermore, a method for automatic detection and correction of fluid transfer errors is implemented, comprising monitoring fluid transfer parameters, detecting deviations from predetermined thresholds, and initiating corrective actions to ensure accurate and efficient fluid transfer.

Novelty and Inventive Step

The new inventive concept's novelty lies in the integration of advanced sensors, real-time monitoring, and self-cleaning mechanisms, which provide a significant improvement over the original patent's limitations. The inventive step is in the combination of these features to achieve efficient, accurate, and safe fluid transfer.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include the use of different types of sensors, such as optical or ultrasonic sensors, or the integration of machine learning algorithms to predict and prevent fluid transfer errors. Variations of the self-cleaning mechanism could include the use of different cleaning agents or the implementation of a sterilization process.

Potential Commercial Applications and Market

The enhanced fluid transfer station has significant commercial potential in the pharmaceutical industry, particularly in hospitals and clinical settings where accurate and efficient fluid transfer is critical. The target market includes robotic pharmaceutical preparation system manufacturers and healthcare providers seeking to improve the safety and efficiency of their fluid transfer processes.
