Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current inventory control systems in medical facilities face challenges in accurately tracking medical devices and medications due to limitations in existing bar-code and magnetic stripe technologies, which result in errors, unaccounted devices, and difficulties in recording 'renegade' devices, leading to safety issues and increased costs.
Innovation Solution
A method and apparatus that utilize wireless communication to automatically identify and assign medical devices to patients within a medical facility network, ensuring accurate tracking and billing, with a high correct-reading ability and integration with a central computer system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If bar-code label scanning and magnetic stripe card technology are used to track medical devices, then tracking capability is provided, but the amount of information that can be embedded is low and reading reliability is only 80-90%
Solution Approach 1:
The patent replaces bar-code and magnetic stripe technologies with RFID (Radio Frequency Identification) technology. RFID tags can be embedded with substantial information and read remotely without line-of-sight requirements, achieving both high information capacity and near 100% reading reliability through wireless electromagnetic field communication.
Solution Approach 2:
The patent changes the physical and informational parameters of the tracking system by transitioning from 2-D bar codes with limited data storage to RFID tags with expanded memory capacity. This allows embedding of detailed device information, serial numbers, and tracking data that can be read remotely with high reliability.
2Reliability
If bar-code readers are used, then device tracking is enabled, but line-of-sight communication requirements create delays and reduce operational efficiency
Solution Approach 1:
The patent substitutes optical line-of-sight bar-code scanning with wireless RFID communication. RFID readers can detect and read tags on medical devices without requiring direct visual contact or precise positioning, eliminating the need for repeated passes and manual alignment, thereby significantly improving operational efficiency while maintaining tracking accuracy.
3Loss of information
If complex bar codes with smaller elements are used to increase information capacity, then more data can be stored, but the elements become more sensitive to smudging and dirt
Solution Approach 1:
The patent replaces physical bar-code labels with RFID tags that store information electronically. This eliminates the problem of smudging and dirt affecting smaller bar-code elements, as RFID data is stored in protected memory and read wirelessly through electromagnetic fields, ensuring both high information capacity and sustained reading reliability regardless of physical condition.
4Ease of operation
If prior art tracking systems are used without network connection, then basic reading function is provided, but error detection and renegade device identification are not possible
Solution Approach 1:
The patent implements a networked RFID system where readers communicate with a central computer or server. This feedback loop allows the system to verify device identities, detect errors by comparing against authorized device databases, identify renegade devices not in the system, and provide real-time alerts, thereby enhancing reliability while maintaining ease of operation through automated processes.

Function Achieved in This Case
This solution provides near 100% accurate tracking and assignment of medical devices, reducing errors, enabling better patient safety, and facilitating recall notifications, while improving billing accuracy and reducing the risk of 'renegade' devices being used.
Implementation Method 1
providing a medical device into a medical treatment area within a wireless range of a medical facility network and automatically identifying the medical device upon introduction into the medical treatment area
Data Source
AI summary
A system and method assigning a medical device to a medical facility is disclosed. Responsive to determining that a wireless connection being formed between a medical device and a wireless communication device inside a medical treatment area, a determination is made that the medical device moved into the medical treatment area and a determination is made as to whether the medical device is currently in an existing inventory associated with the medical facility. When the medical device is not determined to be within the inventory, device identity information is automatically obtained from the medical device and a new medical device record is created for the medical device and stored in the inventory.
