Medical Device Scanner for Inter-Device Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current extracorporeal photopheresis methods, particularly offline systems, face challenges in ensuring proper irradiation of mononuclear cells before reinfusion, leading to potential errors and the need for extensive traceability procedures due to the separation of devices and reliance on paper records.
Innovation Solution
An integrated system comprising a multifunctional automated apheresis device and an independent irradiation device, connected through a scanner and display for electronic communication, ensures that irradiation is successfully completed before proceeding with reinfusion, using a machine-readable indicator to confirm treatment completion and maintain traceability without manual documentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If offline photopheresis methods are used with separate apheresis and irradiation devices, then device versatility and independence are improved, but traceability reliability and error prevention deteriorate due to reliance on paper records and manual documentation
Solution Approach 1:
The patent introduces an intermediary communication system consisting of a display device at the irradiation device and a scanner at the apheresis device. This intermediary electronic communication channel mediates between the separate apheresis and irradiation devices, replacing paper records with digital data transmission to ensure reliable traceability while maintaining device independence.
Solution Approach 2:
The system implements feedback by having the irradiation device send confirmation data back to the apheresis device through the display-scanner communication channel. This feedback loop ensures that the apheresis device receives verification that irradiation was successfully completed, enabling automatic prevention of reinfusion until confirmation is received, thereby improving traceability reliability.
2Device complexity
If offline photopheresis methods are used with separate devices and manual documentation, then device complexity is reduced, but operational efficiency and error prevention deteriorate due to extensive traceability procedures
Solution Approach 1:
The patent replaces the mechanical/manual system of paper-based documentation and manual traceability procedures with an electronic communication system. The display-scanner interface automatically transmits and records irradiation confirmation data, eliminating manual paperwork and significantly improving operational efficiency without adding substantial complexity to the devices.
3Device complexity
If paper-based traceability procedures are used, then device complexity is minimized, but measurement precision and confirmation accuracy of irradiation completion deteriorate
Solution Approach 1:
The patent uses digital copying of data through the display-scanner communication channel instead of manual transcription from paper records. The irradiation device displays digital confirmation data that is scanned and stored in the apheresis device, creating an accurate digital copy of the irradiation completion status, thereby improving measurement precision without significantly increasing device complexity.
