Automated Barrier Sampling System for Pharmaceutical Plants
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for microbiological sampling in pharmaceutical production plants require manual operator intervention via glove ports, leading to contamination risks, variability in sampling conditions, and errors in documentation, making them unreliable and non-reproducible.
Innovation Solution
A fully automated barrier system with a handling device that removes and opens contact samples to perform reproducible surface sampling without human intervention, using a robot arm or similar mechanism to ensure consistent sampling parameters and minimize contamination risks by eliminating the need for glove ports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual sampling via glove ports is used, then sampling can be performed inside the barrier system, but contamination risk increases and sampling reliability decreases
Solution Approach 1:
The automated handling device performs sampling operations autonomously without human intervention. The device retrieves contact samples from the magazine, opens them, performs sampling on surfaces, and returns them automatically, making the system self-sufficient and eliminating contamination risks from manual operations through glove ports
Solution Approach 2:
The patent replaces the manual mechanical operation of sampling through glove ports with an automated handling device that uses mechanical arms, grippers, and automated movement systems to perform all sampling operations, thereby eliminating the need for human operators to physically access the barrier system
2Adaptability or versatility
If manual sampling operations are performed, then flexibility in sampling is maintained, but sampling conditions vary and reproducibility is lost
Solution Approach 1:
The automated handling device maintains sampling flexibility while ensuring reproducibility by programmatically controlling all sampling parameters including pressure, contact time, speed, and positioning. The system can adapt to different sampling locations and surfaces while maintaining consistent operational parameters through automated control, eliminating variability introduced by manual operations
3Loss of information
If manual sampling documentation is performed, then sampling locations can be recorded, but errors in documentation occur and traceability is compromised
Solution Approach 1:
The automated handling device incorporates detection devices that automatically detect and document sampling locations, times, and parameters. The system provides real-time feedback and recording of all sampling operations, eliminating documentation errors and ensuring complete traceability through automated data capture and storage
4Ease of operation
If doors are opened for sampling removal, then samples can be taken out, but contamination of the plant occurs
Solution Approach 1:
The automated handling device performs all sample removal operations autonomously within the barrier system. The device retrieves contact samples from the magazine, performs sampling operations, and returns samples to the magazine or designated locations without requiring door openings, making the system self-sufficient and maintaining continuous barrier integrity
