Drug Inspection Device Using Image Analysis for PTP Bundle Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current drug inspection methods for PTP-packaged drugs rely heavily on visual confirmation by pharmacists, leading to inefficiencies and increased mental strain, as they require disassembly of bundled sheets and manual counting of tablets, which is not accurate or efficient.
Innovation Solution
A drug inspection device that uses image processing and recognition to classify and count drugs by imaging a bundle of PTP-packaged drugs collectively, allowing for accurate drug classification and dosage determination without disassembling the bundle, using stereoscopic imaging and a computer-based system to analyze captured images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If pharmacists perform visual inspection of bundled PTP sheets, then drug classification can be confirmed, but the inspection process requires disassembly of bundles and manual counting which reduces efficiency
Solution Approach 1:
The patent uses image capture to create visual copies of the bundled PTP sheets, allowing the inspection system to analyze multiple sheets simultaneously without physical disassembly. The image processing unit generates digital representations that can be processed automatically, replacing the need for manual handling and counting of individual sheets.
Solution Approach 2:
The patent replaces the mechanical process of manual disassembly and counting with an automated image processing system. The inspection device captures images of the bundled sheets and uses software algorithms to automatically identify drug classifications, count sheets, and verify dosages, eliminating the need for pharmacists to physically manipulate and count each sheet individually.
2Ease of manufacture
If multiple drug sheets are bundled together, then storage and handling are simplified, but individual sheet inspection becomes more complex
Solution Approach 1:
The patent transitions the inspection process from a one-dimensional sequential examination of individual sheets to a two-dimensional simultaneous analysis of multiple sheets through imaging. By capturing images that show multiple sheets in the bundle at once, the system can process information from all sheets in parallel, maintaining the benefits of bundling while simplifying the inspection process.
3Measurement precision
If manual counting of tablets is performed, then dosage verification is possible, but the process is time-consuming and prone to errors
Solution Approach 1:
The patent replaces manual tablet counting with automated image processing techniques. The system captures images of the tablets visible through the PTP packaging and uses computer vision algorithms to automatically count and verify dosages across multiple sheets simultaneously, dramatically reducing the time required while maintaining or improving accuracy compared to manual counting.
