RFID Infusion Line Identification for Spaghetti Syndrome
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The tangling of infusion lines (known as 'spaghetti syndrome') and the difficulty in tracking infusion line expiration in healthcare settings, particularly in intensive care units and operating rooms, pose challenges for clinicians managing multiple infusions, leading to inefficiencies and risks in medication administration.
Innovation Solution
Infusion sets equipped with ultra-high frequency (UHF) radio-frequency identification (RFID) tags and locator devices that store and transmit essential information, allowing clinicians to quickly identify and locate infusion lines using RFID readers and mobile devices, reducing the need for manual tracing and label reading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple infusion lines are connected to a single patient simultaneously, then infusion therapy effectiveness is improved, but spaghetti syndrome occurs making it difficult to identify and manage each infusion line
Solution Approach 1:
RFID tags serve as intermediaries between infusion lines and clinicians. Each infusion line has an RFID tag that stores identification information, allowing the clinician to quickly identify each line by scanning the tag rather than visually tracing through tangled lines. The RFID reader acts as another intermediary that retrieves and displays the stored information.
Solution Approach 2:
The patent creates digital copies of infusion line information stored in RFID tags. Instead of relying on physical labels that can be missed or misread, the system creates electronic copies of identification data that can be quickly accessed and verified through RFID scanning, reducing human error in identification.
2Reliability
If manual tracing of infusion lines is performed to identify medication and parameters, then accurate medication administration is ensured, but time consumption increases
Solution Approach 1:
The RFID tags store infusion line identification information, medication details, and parameters in advance before the clinician needs to access them. This preliminary storage of information eliminates the need for manual tracing during critical moments, allowing rapid retrieval of accurate information through a simple scan.
Solution Approach 2:
The patent replaces the mechanical action of manually tracing infusion lines with an electromagnetic scanning system. The RFID reader uses radio frequency waves to communicate with the RFID tags, automatically retrieving information without requiring physical contact or visual tracing of the infusion lines.
3Loss of information
If labels are used on infusion lines to provide identification, then medication information is visible, but risk of healthcare infection increases
Solution Approach 1:
The patent replaces physical labels with RFID tags that use electromagnetic fields for identification. This substitution eliminates the need for visible paper or plastic labels on infusion lines, thereby removing the potential infection risk associated with these materials while maintaining complete identification capability through digital storage and retrieval.
4Reliability
If infusion lines are tracked manually to monitor expiration, then timely replacement is ensured, but complexity of management increases
Solution Approach 1:
The RFID tags automatically store and maintain infusion line expiration information without requiring manual tracking or intervention. The system serves itself by automatically retrieving and displaying expiration dates when scanned, eliminating the need for clinicians to manually monitor and track multiple expiration dates across numerous infusion lines.

AI summary
An example system for streamlining management of multiple infusion sets includes first and second infusion sets. The first and second infusion sets each include respective infusion lines and respective UHF RFID tags affixed to the respective infusion lines. Each of the UHF RFID tags is configured to receive information associated with the respective infusion sets, store the information, and transmit the information to an RFID reader. The RFID reader is configured to transmit the information to one or more servers after receiving it from the UHF RFID tags. Optionally, the system may also include locator devices affixed to each of the first and second infusion sets. The locator devices are each configured to receive an identification request and, responsive to receiving a request, illuminate an LED, activate a speaker, or activate a vibrator.
