Existing manual counting methods for surgical sponges during surgeries are prone to human error and do not effectively prevent the inadvertent retention of sponges within patients, necessitating a more efficient and accurate tracking system.
Innovation Solution
A surgical article management system utilizing RFID tags and a hand-held reader with a cradle for counting surgical articles, enabling modes for counting-in and counting-out, and ensuring accurate tracking and detection through near-field communication and Bluetooth pairing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual counting methods are used for surgical sponges, then the process is simple and requires no additional equipment, but it is prone to human error and cannot reliably prevent retention of sponges within patients
Solution Approach 1:
The patent replaces manual mechanical counting with an automated RFID system. RFID tags attached to surgical sponges communicate wirelessly with readers, enabling automatic tracking and counting without human intervention. This substitution of mechanical manual counting with electromagnetic field-based automated detection significantly improves reliability while reducing human error.
Solution Approach 2:
The surgical sponges equipped with RFID tags perform self-identification and self-tracking without requiring manual handling or counting by healthcare professionals. The sponges carry their own identification information that is automatically read by RFID readers, making the tracking process autonomous and eliminating dependency on human counting accuracy.
2Measurement precision
If RFID tags and hand-held readers are used for tracking surgical sponges, then counting accuracy is improved, but the system complexity increases due to additional equipment and procedures
Solution Approach 1:
The RFID reader device serves multiple functions including counting sponges, identifying individual sponges, tracking their location, and monitoring their status throughout the surgical procedure. This multi-functionality consolidates what would otherwise require multiple separate systems into a single device, reducing overall system complexity while maintaining high measurement precision.
Solution Approach 2:
The patent introduces RFID tags as intermediary elements that bridge the surgical sponges and the tracking system. These tags act as mediators that carry identification information and enable wireless communication between the sponges and readers, simplifying the interaction mechanism and reducing the complexity of direct tracking systems.
3Reliability
If strict procedures for accounting for each sponge are followed, then patient safety is improved by preventing retained sponges, but the time required for counting and verification increases
Solution Approach 1:
The RFID system enables continuous tracking of surgical sponges throughout the entire surgical procedure without requiring periodic stops for manual counting and verification. The system operates continuously in the background, automatically monitoring sponge locations and status, thereby maintaining patient safety while eliminating time-consuming intermittent counting procedures.
Solution Approach 2:
Surgical sponges are pre-equipped with RFID tags before the surgical procedure begins. This preliminary attachment of identification devices allows for immediate automated tracking from the start of the procedure, eliminating the need for post-procedure counting and verification that would otherwise extend the surgical timeline.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides precise and reliable tracking of surgical sponges, reducing the risk of retention by ensuring accurate inventory management and alerting on the presence of the reader in the cradle, thus enhancing patient safety.
Implementation Method 1
The cradle is operable to determine a presence of the hand-held reader received in the cradle
Implementation Method 2
The hand-held reader may include an RFID reader and wherein the identification tag comprises an RFID tag
Data Source
AI summary
System and method of managing one or more surgical articles, wherein the surgical article can include a surgical sponge comprising an identification element, and wherein managing can include counting, locating, or both. The identification element can be a RFID tag. The RFID tag stores unique identification information relative to the surgical sponge. The system and method for detecting RFID tags may include a hand-held RFID reader operable in a first count-in mode and in a second count-out mode; the hand-held RFID reader may be receivable in a cradle that can determine the presence of the hand-held RFID reader in the cradle; and where operation of the hand-held RFID reader in the second count-out mode is enabled when the hand-held RFID reader is present in the cradle and the second count-out mode is disabled when the hand-held RFID reader is absent from the cradle.
