RFID Tag Hierarchy for Surgical Device Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional distribution management systems for surgical devices and accessories are inefficient and prone to inaccuracies due to manual tracking, which leads to high costs and errors, and traditional identifiers often fail to withstand sterilization processes.
Innovation Solution
The use of radio frequency identification (RFID) tags, including a parent tag attached to a surgical device carrying apparatus and child tags attached to individual devices, allows for efficient tracking and repeated sterilization, enabling accurate identification and management of surgical devices throughout their distribution and sterilization cycles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual tracking and documentation methods are used for surgical devices, then labor costs and time consumption increase, but tracking accuracy may be compromised due to human error
Solution Approach 1:
The patent replaces manual mechanical tracking methods with an automated RFID-based electronic tracking system. RFID tags attached to surgical devices and carrying trays enable automatic identification and tracking without manual intervention, eliminating human error while improving tracking efficiency and accuracy simultaneously.
Solution Approach 2:
The patent creates electronic copies of device identifiers through RFID tags that can be read and tracked multiple times without degrading the original device or identifier. This allows simultaneous tracking at multiple points in the distribution chain without requiring physical handling or manual documentation.
2Reliability
If traditional identifiers are used on surgical devices, then initial tracking is possible, but they cannot withstand repeated sterilization processes
Solution Approach 1:
The patent changes the material and technological parameters of the identifier from traditional labels or barcodes to RFID tags, which have different physical and chemical properties that allow them to withstand extreme temperatures and sterilization processes without degradation, enabling repeated sterilization cycles.
Solution Approach 2:
The patent replaces physical labels or barcodes that are damaged by sterilization with RFID tags that are embedded or attached to the device in a manner that survives sterilization. This substitution eliminates the need to replace identifiers after sterilization, improving both durability and operational efficiency.
3Measurement precision
If detailed manual documentation is performed for each surgical device, then inventory accuracy can be maintained, but significant time and labor resources are consumed
Solution Approach 1:
The RFID system enables devices to essentially track themselves through automatic identification and location tracking. The system self-documented device movement, sterilization status, and inventory status without requiring manual intervention, maintaining precise inventory records while eliminating documentation time.
Solution Approach 2:
The patent replaces manual documentation processes with automated RFID reading and data capture systems that continuously track device status and location, providing precise inventory information without requiring human time or effort for documentation.
4Measurement precision
If identifiers are attached to each individual surgical device, then precise tracking is achieved, but the cost of employing staff to manage and track each identifier increases
Solution Approach 1:
The patent merges the identification functions into an integrated RFID system where tags on individual devices communicate with a centralized tracking system. This consolidation maintains precise device-level identification while reducing the need for separate manual tracking processes and staff, simplifying the overall system complexity.
