Dialysis Line Holder Assembly with Anchor Base
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dialysis systems face challenges in organizing and securing medical lines to prevent contamination, entanglement, and accidental displacement, particularly in environments where space for mounting line holders is limited.
Innovation Solution
A line holder assembly featuring an anchor base made of impact-resistant polymer material, such as silicone, with a nested design that secures lines in a vertical position, providing stability and resistance to movement, and allowing easy repositioning and cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a line holder is mounted on or near the dialysis machine, then lines can be secured in an easy to reach area, but mounting space may not be readily available
Solution Approach 1:
The line holder assembly transitions from a two-dimensional surface mounting approach to a three-dimensional vertical positioning approach. The nest is oriented substantially perpendicular to the plane of the anchor base, allowing the line holder to extend upward from the surface rather than requiring lateral mounting space on the dialysis machine.
Solution Approach 2:
The anchor base with nest structure serves as an intermediary element between the dialysis machine and the line holder. This intermediate component provides a stable mounting foundation that can be positioned on available surfaces (such as the dialysis cart) rather than requiring direct mounting on the machine itself.
2Strength
If the line holder assembly is made of impact-resistant polymer material, then stability and resistance to movement are improved, but the material selection becomes more specific and potentially more expensive
Solution Approach 1:
The line holder assembly utilizes polymer materials with impact-resistant properties, combining durability requirements with manufacturing feasibility. The use of polymer materials allows for molding and shaping while providing the necessary mechanical strength and impact resistance for the application.
3Stability of the object's composition
If the nest is oriented perpendicular to the anchor base, then lines are held in a stable vertical position, but the structure becomes more complex
Solution Approach 1:
The nest structure is integrated with the anchor base in a nested configuration, where the nest is coupled to the anchor base with the nest oriented perpendicular to the anchor base plane. This nested design allows the line holder to be secured within the nest while the entire assembly remains anchored to the surface, providing vertical stability without requiring separate complex mounting mechanisms.

Function Achieved in This Case
Effectively organizes and secures medical lines, reducing the risk of contamination and entanglement while being portable and easy to clean, with enhanced stability and impact resistance.
Implementation Method 1
an anchor base including a portion comprising a polymer material that, when in contact with a surface, resists movement of the line holder assembly across the surface

AI summary
A line holder assembly may include a molded nest coupled to an anchor pad or base having a flat bottom with sufficient surface area in contact with a table or other surface to secure the line holder assembly in place during use. The nest is designed to extend around a cart or table edge and having tabs to accept a line holder for holding and organizing lines and which may be disposed in a vertical position. The anchor base may be made of or otherwise include a flexible, rubber-like material, such as silicone, and thereby use the material's natural stickiness to provide fixation to the table or cart. The line holder assembly may be beneficially used in connection with a home dialysis machine, such as a peritoneal dialysis (PD) cycler, in which lines and connectors are desirably organized and anchored during a dialysis treatment.
