Remote Dialysis Message Processing with Visual Contact Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dialysis machines face challenges in ensuring safety and reducing the risk of cross-contamination due to the need for frequent disinfection of touchscreens, which can be time-consuming and prone to neglect, and existing remote control systems do not adequately address operational safety and flexibility.
Innovation Solution
Implementing a remote processing method for dialysis machines that requires a security criterion check, using an identification device to verify visual contact between the operator and the patient or machine, allowing secure remote control only on approved application devices that meet defined safety conditions, and enabling message processing through digital and analog signal exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If remote control of dialysis machines is implemented, then operational flexibility and efficiency are improved, but safety risks increase due to potential misuse and inability to verify operator-patient visual contact
Solution Approach 1:
The patent introduces an intermediary verification system consisting of detection devices (cameras, sensors) that monitor and verify the spatial relationship between the operator and patient during remote control operations. This intermediary layer ensures safety criteria are met before allowing remote message processing, thus resolving the contradiction between operational efficiency and safety.
Solution Approach 2:
The system dynamically changes the operational parameters of remote control based on verified safety conditions. When visual contact and proximity criteria are confirmed through detection devices, the system transitions from a restricted state to an enabled state for remote message processing, allowing flexible yet safe operation.
2Object-affected harmful factors
If frequent disinfection of touchscreen interfaces is performed, then cross-contamination risk is reduced, but time consumption and operational burden increase
Solution Approach 1:
The patent extracts the message processing function from the physical touchscreen interface and relocates it to a remote device. By taking out the critical control function from the contaminated surface, the system eliminates the need for frequent disinfection while maintaining operational safety, thus resolving the contradiction between contamination prevention and time efficiency.
Solution Approach 2:
The system creates a digital copy of the dialysis machine's interface and messages on a remote device. This copy allows operators to interact with the system without physically touching the touchscreen, eliminating cross-contamination risks while preserving full operational capability.
3Adaptability or versatility
If remote message processing is allowed without security verification, then operational flexibility increases, but safety and security risks increase due to potential misuse
Solution Approach 1:
The patent implements preliminary verification actions before enabling remote message processing. Detection devices first verify that safety criteria (visual contact, proximity) are met, and only after this preliminary check passes is remote processing authorized. This preliminary action ensures security while maintaining operational flexibility.
Solution Approach 2:
The system continuously monitors safety criteria through detection devices and provides feedback to control whether remote processing should be enabled or disabled. This real-time feedback mechanism ensures that operational flexibility is maintained only when security conditions are satisfied, resolving the contradiction between adaptability and security.
