Mobile Tank Apparatus for Dialysis Fluid Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dialysis systems require complex handling and do not allow for easy fluid changes while the patient remains connected, as they often rely on fixed tanks within the blood treatment device.
Innovation Solution
A system where a mobile tank apparatus can be connected to the blood treatment device, allowing for the removal and replenishment of dialysis fluid without the need for a tank on the device itself, enabling flexible fluid management and automatic or demand-driven connection establishment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed tank is integrated into the blood treatment device, then the device structure is stable and fluid supply is reliable, but the device complexity increases and fluid changes require patient disconnection
Solution Approach 1:
The system separates the fluid storage function from the treatment device by using an external mobile tank apparatus. The tank is divided into separate compartments for fresh dialysis fluid and waste fluid, allowing independent management of fluid supply and disposal without increasing the complexity of the main treatment device.
Solution Approach 2:
A mobile tank apparatus serves as an intermediary between the fluid supply source and the blood treatment device. This intermediate component enables fluid changes without requiring patient disconnection, as the mobile tank can be replaced or refilled while the patient remains connected to the treatment device through the fluid connection system.
2Productivity
If the total amount of dialysis fluid is provided in a tank prior to treatment, then the treatment can start immediately, but the system lacks flexibility for fluid changes during treatment
Solution Approach 1:
The system transitions from a static fixed tank to a dynamic mobile tank apparatus that can be moved, replaced, or refilled during treatment. The mobile tank design allows the system to adapt to different treatment requirements and enables fluid changes without interrupting the treatment, combining the benefits of immediate treatment start with flexible fluid management.
Solution Approach 2:
The mobile tank apparatus serves multiple functions: it stores fresh dialysis fluid, collects waste fluid, and can be replaced or refilled during treatment. This multi-functional design provides both the immediate availability needed for treatment start and the flexibility required for fluid changes during the procedure.
3Ease of manufacture
If manual handling of fluid tanks is required, then the system is simple to construct, but labor effort increases and contamination risk rises
Solution Approach 1:
The mobile tank apparatus is designed with features that enable self-service operation, including automatic fluid level monitoring, integrated waste fluid drainage, and standardized connection interfaces. These features reduce the labor effort required for fluid changes and minimize contamination risk by reducing manual handling, while maintaining simple system construction.
4Quantity of substance
If the patient is disconnected for fluid changes, then complete fluid replacement is possible, but treatment interruption occurs and patient comfort decreases
Solution Approach 1:
The mobile tank apparatus acts as a buffer intermediary between the dialysis circuit and the fluid supply source. This allows complete fluid replacement in the mobile tank without requiring disconnection of the patient from the treatment device, as the fluid exchange occurs in the intermediary tank rather than in the patient connection line, eliminating treatment interruptions.
