UHF RFID Surgical Sponge Tracking for Fast Missing Item Location
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surgical articles, particularly sponges and towels, are difficult to account for during and after surgery due to their flexible and absorbent nature, leading to potential inadvertent retention in patients, and existing tracking systems are costly and time-consuming with limited ability to locate missing items.
Innovation Solution
Implementing UHF RFID tags on surgical articles that provide unique identification information for each article and the entire pack, allowing for efficient tracking and location of missing items through electronic counting and interrogation signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual counting of surgical articles is performed, then all items can be accounted for, but the process is labor intensive and time consuming
Solution Approach 1:
The patent replaces manual mechanical counting with automated RFID scanning systems. RFID readers automatically detect and track surgical articles through electromagnetic fields, eliminating the need for manual visual inspection and counting by surgical teams, thereby reducing time while maintaining accuracy
2Productivity
If barcoding and radio frequency tagging systems are utilized, then workload and expense are reduced, but the ability to locate missing items is limited
Solution Approach 1:
The patent introduces RFID tags as intermediary devices attached to surgical articles. These tags contain unique identifiers that enable both automated tracking for productivity improvement and precise location detection through RFID readers, resolving the contradiction between tracking efficiency and location capability
3Object-generated harmful factors
If surgical sponges and towels are made of flexible absorbent fabric, then they effectively absorb body fluids, but they become difficult to distinguish and account for
Solution Approach 1:
The patent uses RFID tags that create an electronic copy or digital representation of each surgical article's identity and location. This electronic identifier allows the system to track and distinguish each absorbent sponge or towel individually, even when they are physically indistinguishable due to their flexible fabric nature and saturation with body fluids

AI summary
Surgical articles, such as sponges, are provided in a pack which contains individual surgical articles having UHF RFID or other electronic labels which provide both (a) unique identification information for each article as well as (b) unique identification information for all articles in the pack. Prior to the surgical procedure, the labels are scanned and the identification information for all articles in the pack uploaded to a processor to create a list of available individual surgical articles. At the end of the surgical procedure, the surgical articles are collected and the electronic labels read and compared to the initial list to determine if there are any unaccounted individual surgical articles. The UHF RFID tag may then be used to determine a location of the unaccounted article outside the patient's body.
