Dialysis Machine Automatic Priming and Integrity Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dialysis systems require manual intervention for priming and integrity testing, which is time-consuming and inefficient, and often require users to arrive early to power on the machine before a treatment, lacking automated scheduling and alert features.
Innovation Solution
The implementation of an automatic priming method that includes integrity tests such as battery, conductivity, and temperature tests, with a user interface guiding the user through the priming process, and the ability to automatically power on the dialysis machine at a scheduled time, along with alert systems to notify personnel before activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual priming and integrity testing procedures are used, then the dialysis machine requires user intervention for each step, but this increases the time required for setup and reduces efficiency
Solution Approach 1:
The dialysis machine automatically performs integrity tests on itself without requiring user intervention. The system self-tests various components including the dialyzer, blood lines, and pumps by circulating test fluids and monitoring parameters, thereby reducing setup time while maintaining operational safety
Solution Approach 2:
The system performs integrity tests automatically during the priming sequence before actual dialysis treatment begins. This preliminary automated testing ensures all components are functioning correctly before patient use, eliminating the need for separate manual testing steps
2Ease of operation
If the dialysis machine is powered on manually before treatment, then the user can control when the machine is ready, but this requires the user to arrive early and reduces convenience
Solution Approach 1:
The dialysis machine is configured to automatically power on at a predetermined time before the scheduled treatment. This preliminary automated activation allows the machine to complete its startup sequence and be ready for use without requiring the user to arrive early or manually activate the system
3Reliability
If comprehensive integrity tests are performed manually, then system safety is ensured, but the testing process becomes time-consuming and complex
Solution Approach 1:
The dialysis machine automatically performs multiple integrity tests including pressure testing of the dialyzer, leak detection in blood lines, and pump functionality verification. The system self-monitors these tests and interprets results without requiring user intervention, maintaining comprehensive safety checks while simplifying the user experience
Solution Approach 2:
The integrity testing functions are merged into the existing priming sequence. Multiple tests (pressure testing, leak detection, flow verification) are combined and executed automatically during the priming phase, ensuring system safety without adding separate complex testing procedures
