Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack efficient real-time tracking and monitoring of surgical tools across multiple locations, leading to challenges in infection control, particularly in scenarios like Creutzfeldt-Jakob disease outbreaks, where improper cleaning and handling can cause contamination and spread of infections.
Innovation Solution
A computerized system utilizing RFID-enabled tags paired with surgical instruments, which communicate location data to a central server via signal receiving units, allowing for real-time monitoring and notification of tools involved in detected events, ensuring proper cleaning, sanitizing, or disposal protocols are followed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If surgical tools are tracked across multiple locations using manual recording methods, then the system complexity is low, but the tracking speed and real-time monitoring capability are insufficient
Solution Approach 1:
The patent replaces manual mechanical recording systems with an automated RFID-based tracking system. RFID tags attached to surgical tools communicate wirelessly with receiving units at various locations, eliminating the need for manual data entry and enabling real-time tracking without increasing operational complexity for users
Solution Approach 2:
The patent introduces RFID tags as intermediary devices between surgical tools and the tracking system. These tags serve as mediators that automatically transmit location information to receiving units, enabling fast tracking while keeping the overall system simple to operate as users only need to attach the tag once
2Measurement precision
If real-time tracking of surgical tools is implemented using automated systems, then the tracking accuracy and response time improve, but the device complexity and cost increase
Solution Approach 1:
The patent divides the tracking system into independent modular components: RFID tags attached to individual tools, receiving units at each location, and a central server. This segmentation allows each component to be simple and inexpensive while achieving high tracking accuracy through their coordinated operation
Solution Approach 2:
The RFID tags automatically transmit their identification information without requiring manual intervention. The system serves itself by having tags continuously broadcast their identity, which receiving units automatically capture and report to the central server, achieving high precision tracking with minimal operational complexity
3Reliability
If surgical tools are monitored for infection control events, then the infection control effectiveness improves, but the time required to locate and recall tools increases
Solution Approach 1:
The patent implements a feedback mechanism where the central server continuously receives location data from receiving units and maintains an updated record of each tool's current location. When an infection control event is detected, the system instantly queries the current locations of affected tools and notifies relevant personnel, enabling rapid response while maintaining high infection control effectiveness
Solution Approach 2:
The system performs preliminary actions by continuously tracking and recording tool locations before any infection control event occurs. This pre-established location information allows for immediate tool recall when needed, reducing response time while maintaining reliable infection control through advance preparation
