Solution Overview
Problem
Existing medical device management systems lack efficient methods for tracking and ensuring compliance with procedural protocols, device calibration, and inventory management, particularly for disposable and single-use devices, leading to potential errors and inefficiencies.
Innovation Solution
Integration of RFID tags with medical devices and emitters to provide real-time information and automatic calibration, tracking, and compliance monitoring, utilizing passive RFID tags that do not require a power source and can be integrated into various medical devices and systems, including fiber optic stylets, ultrasound systems, and medical device kits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual tracking and data entry methods are used for medical devices, then device management can be performed without additional components, but tracking efficiency is low and manual data entry errors occur
Solution Approach 1:
The RFID tag enables the medical device to automatically provide identification and tracking information without requiring manual data entry. The device self-identifies through the RFID tag when interrogated by the emitter, eliminating the need for manual tracking processes and reducing human error while improving productivity.
Solution Approach 2:
The patent replaces manual mechanical tracking methods with an electromagnetic field-based RFID system. The RFID emitter uses electromagnetic signals to automatically query and track the medical device, substituting the manual mechanical process of tracking and data entry with an automated electromagnetic communication system.
2Reliability
If RFID tags are integrated into medical devices, then automatic tracking and compliance monitoring are enabled, but device complexity increases
Solution Approach 1:
The RFID system is segmented into separate functional components: a passive RFID tag attached to or integrated with the medical device, and an RFID emitter integrated into the medical device holder or tracking system. This segmentation allows the compliance monitoring functionality to be added without significantly complicating the medical device itself, as the RFID tag is a standalone component.
Solution Approach 2:
The RFID tag serves as an intermediary component that bridges the medical device and the tracking system. Rather than directly integrating complex monitoring electronics into the medical device, the passive RFID tag acts as a mediator that stores identification information and communicates with the emitter, enabling compliance monitoring while keeping the medical device relatively simple.
3Ease of manufacture
If passive RFID tags are used that do not require a power source, then ease of manufacture is improved, but the range of interrogation is limited
Solution Approach 1:
The system optimizes the electromagnetic parameters of the RFID emitter to achieve effective communication with passive RFID tags at the required interrogation distances. By adjusting parameters such as signal power, frequency, and antenna design of the emitter, the system compensates for the limitations of passive tags and achieves sufficient interrogation range while maintaining the manufacturing advantages of passive tags.

Data Source
AI summary
Disclosed herein are RFID enabled medical device systems including an RFID emitter configured to provide an interrogation signal that impinges on an RFID tag associated with a medical device to trigger a response signal. The response signal can indicate and presence or absence of the medical device proximate to the RFID emitter. A console communicatively coupled to the RFID emitter can determine, record, and analyze procedural or usage information about the medical device. Further information about the medical device can be encoded within the response signal and provided to the console. Console settings can be automatically updated based on the information within the response signal. Additional modalities are also contemplated including optical image recognition of medical device kits. Further AR viewers can provide image overlays to guide a user in correct procedure. Procedural compliance can be automatically recorded and monitored.
