Pharmacy Workflow Management System with Dual Counters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pharmacy workflow management systems and tablet counters face challenges in accurately counting tablets, particularly when using incorrectly calibrated or sized cassettes, leading to errors in prescription fulfillment and inefficiencies in workflow management.
Innovation Solution
A pharmacy workflow management system incorporating multiple automatic object counters and a data processing platform that compares counts from different counters, verifies medication using barcode scanning, and manages workflow to ensure accurate counting and prescription fulfillment, allowing for manual or automated feeding of tablets from cassettes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single automatic object counter is used to count tablets, then counting speed is improved, but counting accuracy deteriorates when cassettes are incorrectly calibrated or sized
Solution Approach 1:
The system uses multiple object counters that simultaneously count tablets from the same cassette, and a data processing platform compares the counts to detect discrepancies. When calibration errors or sizing issues occur, the feedback mechanism identifies the problem through count mismatches, allowing for correction while maintaining automated high-speed counting.
Solution Approach 2:
The system performs preliminary verification by having multiple counters independently count the same tablet batch before finalizing the prescription fulfillment. This preliminary cross-checking action prevents inaccurate counting from propagating to patient medication, resolving the accuracy issue while preserving productivity.
2Measurement precision
If multiple automatic object counters are added to verify counting accuracy, then counting accuracy is improved, but device complexity increases
Solution Approach 1:
The multiple object counters are integrated into a unified pharmacy workflow management system that performs both counting and verification functions. The data processing platform serves multiple purposes: comparing counts, detecting calibration errors, and managing prescription fulfillment. This multi-functionality approach improves accuracy while minimizing the increase in overall system complexity.
3Adaptability or versatility
If manual tablet pouring is used instead of automated feeders, then adaptability to different cassette types is improved, but productivity decreases
Solution Approach 1:
The system provides feedback to the pharmacist when count discrepancies are detected, indicating potential cassette calibration or sizing issues. This allows the pharmacist to manually adjust or replace cassettes while maintaining the benefits of automated counting for standard configurations, balancing adaptability with productivity.
Solution Approach 2:
The data processing platform acts as an intermediary between the automated counters and the pharmacist, managing the workflow and determining when manual intervention is needed. This intermediary coordination allows the system to maintain high productivity through automation while enabling manual cassette handling when adaptability is required.
Data Source
AI summary
A pharmacy workflow management system including plural counters and a pharmacy workflow management method. In embodiments, the system includes a housing, a first automatic object counter and a cassette dispenser which feeds objects from a cassette mounted thereto to the first object counter. A second object counter counts objects fed from a cassette mounted to the cassette dispenser. A data processing platform within the housing is programmed with instructions that enable the system to compare the counts from the first and second object counters. The data processing platform also provides for management of pharmacy workflow by providing improved control of prescription fulfillment.
