Surgical Cassette Identification Using RFID Encoding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical cassette identification systems only recognize the type of cassette installed, failing to provide information on its specific performance characteristics, which limits the ability of surgical consoles to adjust operating parameters accordingly.
Innovation Solution
Implementing a cassette identification system using bar coding or RFID technology to encode and read unique information such as lot number, pressure sensor calibration data, flow, and pressure data, allowing the surgical console to recognize and adjust for the specific performance characteristics of each cassette.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional cassette identification systems using frangible tabs are used, then the surgical console can recognize the type of cassette installed, but the system cannot identify specific performance characteristics of individual cassettes
Solution Approach 1:
The patent uses bar codes or RFID tags to create information copies of cassette performance characteristics. These codes encode specific performance data (flow rates, pressure values, calibration information) that can be read by the surgical console without physically altering the cassette or requiring complex mechanical recognition systems.
Solution Approach 2:
The patent replaces the mechanical frangible tab system with optical (bar code) or electromagnetic (RFID) recognition systems. This substitution allows the console to read cassette identification information remotely and automatically, eliminating the need for physical tab manipulation and providing more comprehensive data storage capability.
2Adaptability or versatility
If cassette-specific performance data is encoded and stored, then the surgical console can adjust operating parameters for optimal performance, but the manufacturing and tracking process becomes more complex
Solution Approach 1:
The patent encodes cassette performance characteristics during the manufacturing process itself. Performance data such as flow rates, pressure values, and calibration information are captured when the cassette is tested at manufacture and stored in the bar code or RFID tag before the cassette leaves the factory. This preliminary encoding eliminates the need for separate data collection steps later.
Solution Approach 2:
The patent changes the state of cassette identification from simple mechanical tabs to encoded data structures containing multiple performance parameters. The bar code or RFID tag stores numerical values representing flow rates, pressure thresholds, and calibration data, allowing the console to read and adjust operating parameters based on specific cassette characteristics.
3Reliability
If bar coding or RFID technology is implemented for cassette identification, then unique cassette information can be recognized and processed, but the system requires additional hardware and software integration
Solution Approach 1:
The patent implements a universal identification system using standard bar code or RFID technology that can be integrated into existing surgical console architectures. These technologies are widely used across different industries and can store multiple types of information (cassette type, performance characteristics, calibration data, manufacturing batch information) using the same hardware platform.
Data Source
AI summary
A surgical system and cassette, the cassette having an identification method that is specific to the cassette. Suitable methods include bar coding or Radio Frequency Identification (“RFID”). Cassette information that may be encoded include features such as lot number and performance characteristics, such as pressure sensor calibration data, flow and pressure data and any other performance characteristics of the cassette captured during testing of the cassette at manufacture.
