API Seed Crystal Transfer Sleeve for Closed Powder Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The storage, transfer, and dispensing of active pharmaceutical ingredients (APIs) in powder form require extensive clean room protocols and personal protective equipment (PPE) to prevent contamination and cross-contamination, which is cumbersome and inefficient.
Innovation Solution
A transfer station apparatus with a flexible feed sleeve and piping assembly, featuring a removable flexible conduit liner, allows for the transfer of APIs without the need for clean rooms or PPE, using a flow control device and containment bags to isolate the contaminated atmosphere from the room atmosphere, ensuring minimal particulate leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If APIs are stored and transferred in traditional open systems, then operators can access and dispense materials easily, but contamination and cross-contamination risks increase significantly
Solution Approach 1:
The patent employs a flexible feed sleeve that forms a sealed barrier between the API bulk bag and the receiving container. This flexible membrane allows for easy connection and disconnection while maintaining containment, enabling operators to transfer APIs without exposing them to the external environment, thus preventing contamination while keeping operations simple.
Solution Approach 2:
The system creates a closed transfer environment where APIs remain contained within the flexible feed sleeve and piping assembly during transfer. This isolated environment prevents contact with external contaminants and eliminates the need for operators to work in exposed conditions, maintaining product purity without complicating operational procedures.
2Reliability
If clean room protocols and PPE are used for API handling, then product purity is maintained, but operational efficiency and speed decrease
Solution Approach 1:
The patent extracts the contamination risk from the transfer process by implementing a closed system with a flexible feed sleeve that isolates the API from the external environment. This eliminates the need for clean room protocols and PPE, allowing operators to perform transfers at normal speed without compromising product purity.
Solution Approach 2:
The flexible feed sleeve is designed as a disposable component that can be easily replaced after each use. This eliminates the need for time-consuming cleaning and decontamination procedures between transfers, maintaining product purity while significantly increasing operational speed and productivity.
3Reliability
If the piping assembly is cleaned thoroughly after each transfer, then cross-contamination is prevented, but time and resources are consumed
Solution Approach 1:
The flexible conduit liner is designed as a disposable component that lines the interior of the piping assembly. After each transfer, the liner is removed and discarded, eliminating the need for thorough cleaning of the piping assembly. This prevents cross-contamination while saving significant time and resources that would otherwise be spent on decontamination procedures.
Solution Approach 2:
The piping assembly is segmented into a reusable outer structure and a disposable inner liner. This segmentation allows the reusable portion to remain in place while the contaminated liner is easily removed and replaced, preventing cross-contamination without requiring cleaning of the permanent infrastructure, thus reducing decontamination time.

AI summary
The present disclosure is directed to a big-bag transfer station for API seed crystals. The transfer station may permit the filling of smaller containers, such as bags or pouches, from a large container, such as a big bag. The transfer station may permit the transfer without contaminating the atmosphere of the room in which the station is housed. Additionally, the transfer station may limit cross-contamination between filling cycles by employing single-use liners.
