Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surgical instrument kits are expensive and prone to misplacement due to inefficient tracking methods, leading to significant financial losses for hospitals and surgery centers, with existing tracking technologies being cumbersome and costly.
Innovation Solution
A system utilizing Bluetooth® Low Energy (BTLE) devices housed in a waterproof and heat-resistant clamshell configuration, integrated with surgical instrument kits, enables precise geolocation and identification through a handheld device, updating a secure network for real-time tracking and alerting responsible personnel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RFID tags are used to track instrument kits, then tracking capability is improved, but device complexity and cost increase
Solution Approach 1:
The patent extracts the tracking functionality from complex RFID hardware systems and implements it using a simple Bluetooth Low Energy (BLE) device that can be easily attached to instrument kits. This extraction principle resolves the contradiction by maintaining tracking capability while eliminating the need for complex infrastructure hardware installation.
Solution Approach 2:
The patent uses a simplified copy of tracking technology - instead of implementing full RFID functionality with complex hardware, it employs a lightweight BLE device that replicates the essential tracking function. This copying approach maintains the core tracking capability while dramatically reducing device complexity and installation requirements.
2Device complexity
If manual tracking methods are used, then device complexity is reduced, but productivity and accuracy deteriorate
Solution Approach 1:
The tracking system operates autonomously without requiring manual intervention. The BLE device automatically transmits location data, and the system self-updates the central server with instrument kit locations. This self-service mechanism dramatically improves tracking productivity and accuracy while keeping the device complexity low, as no manual tracking operations are required.
Solution Approach 2:
The system implements continuous feedback loops where the BLE device constantly reports location information to a central server, which then provides real-time tracking data. This automated feedback mechanism eliminates manual tracking errors and significantly improves tracking efficiency while maintaining system simplicity.
3Reliability
If existing tracking systems are implemented, then tracking capability is improved, but loss of time for installation and maintenance increases
Solution Approach 1:
The tracking system is segmented into independent, modular components - a small BLE device that can be separately attached to each instrument kit without requiring system-wide installation. This segmentation allows for rapid deployment and easy maintenance, resolving the contradiction by maintaining tracking accuracy while minimizing installation and maintenance time investment.

AI summary
Systems and methods herein provide for tracking surgical instrument kits. One system includes a surgical instrument kit operable to retain a plurality of surgical instruments for sterilization in an autoclave, a Bluetooth® low energy (BTLE) device operable to transmit a signal for locating and identifying the surgical instrument kit, a battery operable to provide power to the BTLE device, and a housing operable to retain the BTLE device and the battery and to withstand temperatures in excess of 250 degrees Fahrenheit. Then, a handheld computing device can detect the signal from the BTLE device and determine a geolocation and an identification of the BTLE device for transmission to a secure network. The system also includes a computing system that processes the geolocation and the identification of the BTLE device and alerts a user responsible for the surgical instrument kit.
