Dialysis Parameter Adjustment Using Patient Comfort Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blood treatment systems do not adequately consider patient comfort during dialysis, leading to potential discomfort and psychological aversion due to inconsistent treatment parameters.
Innovation Solution
Incorporation of a patient comfort feedback mechanism in blood treatment machines that allows real-time adjustment of parameters based on subjective patient input, such as ultrafiltration rate, to enhance comfort and reduce discomfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fixed treatment parameters are used throughout the dialysis session, then the treatment protocol is simple to implement, but patient comfort deteriorates due to inability to adapt to changing patient needs
Solution Approach 1:
The patent implements dynamic adjustment of treatment parameters (ultrafiltration rate, blood flow rate, dialysate flow rate) based on real-time patient comfort feedback. The system transitions from static fixed parameters to dynamic adaptive parameters that automatically adjust during the dialysis session according to patient comfort level input through the feedback mechanism.
Solution Approach 2:
The patent introduces a patient comfort feedback mechanism that continuously receives patient comfort level input and feeds this information back to the control system. This closed-loop feedback enables the system to automatically adjust treatment parameters in response to patient comfort changes, resolving the contradiction between operational simplicity and adaptability.
2Adaptability or versatility
If treatment parameters are frequently adjusted during dialysis, then patient comfort is improved through adaptive treatment, but treatment complexity increases
Solution Approach 1:
The patent implements a self-adjusting control system that automatically modifies treatment parameters based on patient comfort feedback without requiring manual intervention from operators. The system serves itself by autonomously interpreting comfort level input and executing appropriate parameter adjustments, thereby managing complexity internally while maintaining adaptability.
Solution Approach 2:
The patent focuses on changing specific treatment parameters (ultrafiltration rate, blood flow rate, dialysate flow rate) in response to patient comfort feedback. By targeting key parameters for adjustment rather than overhauling the entire control system, the patent achieves adaptability with controlled complexity through selective parameter modification.
3Adaptability or versatility
If manual monitoring and adjustment of treatment parameters is performed, then treatment flexibility can be achieved, but time consumption and operator workload increase
Solution Approach 1:
The patent replaces manual mechanical monitoring and adjustment operations with an automated electronic control system. The system electronically monitors patient comfort feedback and automatically adjusts treatment parameters, substituting manual operator actions with automated electronic control to eliminate time loss and reduce operator workload while maintaining treatment flexibility.
Solution Approach 2:
The patent enables continuous automatic adjustment of treatment parameters throughout the dialysis session based on ongoing patient comfort feedback. This continuous adaptive action eliminates interruptions for manual monitoring and adjustment, maintaining treatment flexibility while optimizing treatment time and reducing operator time consumption through uninterrupted automated control.
