Pneumatic Cuff Identification by Valve Pressure Curve Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pneumatic cuffs are prone to operator error due to incorrect selection of type, size, or brand, leading to ineffective medical care, as current systems rely heavily on manual verification and lack accurate identification methods.
Innovation Solution
Integrating unique valves in the pneumatic pathway of cuffs that generate distinct pressure-time curves, allowing a processor to identify the correct cuff type by comparing these curves with reference values, using advanced data validation techniques to ensure accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual cuff selection is used, then operator flexibility is maintained, but operator errors increase leading to incorrect pressure application
Solution Approach 1:
The system performs self-identification by automatically detecting the cuff type through pressure curve analysis during inflation, eliminating the need for manual operator selection and reducing human error in cuff selection
Solution Approach 2:
The system provides feedback to the operator by comparing the measured pressure curve against stored reference curves, automatically identifying the cuff type and confirming correct cuff selection through the display interface
2Measurement precision
If automated cuff identification is implemented, then operator errors are reduced, but device complexity increases due to additional sensors and processing
Solution Approach 1:
The existing pressure sensor and processor in the pneumatic control system are utilized for dual purposes: traditional blood pressure measurement and automated cuff type identification, eliminating the need for separate dedicated sensors and reducing overall system complexity
Solution Approach 2:
Reference pressure curves for different cuff types are pre-stored in the system memory, enabling rapid automated identification when a cuff is connected, eliminating the need for complex real-time analysis algorithms
3Measurement precision
If pressure curve analysis is used for cuff identification, then identification accuracy improves, but measurement time increases during cuff connection
Solution Approach 1:
The system performs cuff identification using only the initial pressure curve data collected during the first few seconds of cuff inflation, before full inflation is completed, allowing rapid identification without delaying the overall medical procedure
Solution Approach 2:
Reference pressure curves are pre-stored in the system, enabling immediate comparison and identification as soon as the cuff begins to inflate, eliminating the need for lengthy measurement or analysis periods

AI summary
A system and method for automatic determination of type of pneumatic cuff is disclosed. A system can include a pneumatic cuff with an integrated valve, and a console connectable to the pneumatic cuff. The console can be a pneumatic control system that can include a processor and memory including instructions, which when executed by the processor causes the processor to: inflate the pneumatic cuff through the integrated valve past a threshold pressure such that the integrated valve opens, receive sensor data indicative of a pressure curve during inflation of the pneumatic cuff, compare the pressure curve to stored pressure curves, determine a recommendation, based on the comparison, including information verifying the type of pneumatic cuff attached, and output the recommendation to a user.
