Solution Overview
Problem
Current methods for controlling blood treatment devices after completion of treatment are inefficient and prone to human error, requiring manual intervention and potentially compromising hygiene and safety.
Innovation Solution
An automated method for controlling blood treatment devices, involving steps such as closing patient hose clamps, conveying dialysis fluid, and using a dialysis fluid pump to manage the extracorporeal blood circuit, which includes a blood filter with a membrane separating blood and dialysis fluid chambers, to facilitate rinsing and preparation for subsequent use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual methods are used to control blood treatment device after treatment, then flexibility and adaptability are maintained, but time consumption and risk of human error increase
Solution Approach 1:
The control device automatically executes the rinsing and preparation method without requiring manual intervention. The system self-regulates by automatically closing clamps, activating pumps, controlling fluid flow rates, and monitoring process parameters, thereby eliminating human error and reducing time consumption while maintaining procedural flexibility through programmable sequences.
2Reliability
If automated control is implemented for post-treatment procedures, then time efficiency and precision are improved, but device complexity increases
Solution Approach 1:
The control device integrates multiple functions into a single automated system that can perform clamp actuation, pump control, fluid flow regulation, and process monitoring. This multi-functional approach consolidates what would otherwise require separate manual operations, achieving high reliability through automation while managing complexity through functional integration rather than proliferation of separate components.
3Object-affected harmful factors
If manual intervention is required for post-treatment procedures, then ease of operation is maintained, but hygiene and safety may be compromised
Solution Approach 1:
The system replaces manual mechanical operations with automated electronic control. Electronic signals actuate clamps, control pumps, and regulate fluid flow, eliminating the need for physical manual manipulation of blood treatment components. This substitution maintains ease of operation through simple interface interaction while dramatically improving hygiene and safety by preventing human contact with potentially contaminated surfaces and fluids.
