Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Apheresis systems face issues with incorrect loading of disposables, leading to leaks and termination of procedures due to improper positioning of disposable kits, which can result in loss of blood components.
Innovation Solution
The use of optical and audio systems, combined with a processor, to detect the position of disposables in medical devices, such as apheresis machines, to determine if they are correctly positioned, preventing leaks and ensuring proper operation by alerting operators or stopping the process until correct alignment is achieved.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual loading of disposable kits is used in apheresis machines, then the device complexity is reduced, but the positioning accuracy and reliability of disposable loading deteriorates leading to leaks and procedure termination
Solution Approach 1:
The patent replaces manual mechanical loading with an automated optical detection system. Optical sensors and cameras automatically detect and verify the positioning of disposable kits, eliminating the need for manual alignment while improving positioning accuracy and preventing leaks through real-time monitoring.
Solution Approach 2:
The system implements real-time feedback through optical sensors that continuously monitor the positioning of disposable kits. The system provides visual or audible alerts when misalignment is detected, allowing operators to correct positioning errors before they cause leaks or procedure termination, thereby improving reliability.
2Adaptability or versatility
If multiple step set-up and configuration is required for apheresis procedures, then the adaptability of the system is improved, but the ease of operation deteriorates increasing the risk of incorrect loading
Solution Approach 1:
The system performs preliminary detection and verification of disposable kit positioning before the apheresis procedure begins. Optical sensors scan and confirm correct alignment in advance, allowing operators to identify and correct loading errors before they affect procedure outcomes, thus simplifying operation while maintaining adaptability.
Solution Approach 2:
The system automatically detects and verifies disposable kit positioning without requiring extensive manual configuration steps. The optical detection system performs self-verification of loading correctness, reducing the burden on operators while maintaining system adaptability through automated guidance and alerts.
