Adjustable Infusion Element for Glucose Regulation Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing infusion sets for glucose regulation systems, such as those used by diabetes patients, require separate components for insulin and glucagon, leading to increased costs and reduced flexibility due to mischanneling prevention mechanisms.
Innovation Solution
An adjustable infusion element that can be adapted from a neutral condition to specific conditions for either insulin or glucagon, ensuring compatibility with only one type of transport element, thereby reducing the need for multiple components and enhancing safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different connectors are provided for insulin and glucagon to prevent mischanneling, then safety is enhanced, but costs increase and flexibility decreases
Solution Approach 1:
The connector is designed with a movable element that can be adjusted between a first position (allowing connection to first type of transport element) and a second position (allowing connection to second type of transport element). This dynamic adjustment capability enables a single connector to replace multiple fixed connectors, reducing device complexity while maintaining safety through controlled adaptability.
Solution Approach 2:
The single connector is designed to perform multiple functions by connecting to different types of transport elements (first type for insulin, second type for glucagon) through position adjustment. This multi-functional design eliminates the need for separate dedicated connectors for each substance, reducing costs and improving flexibility while preventing mischanneling through the adjustment mechanism.
2Reliability
If separate infusion elements are provided for insulin and glucagon, then mischanneling is prevented, but costs increase and user flexibility decreases
Solution Approach 1:
The movable element in the connector allows the infusion element to be dynamically reconfigured between different connection states. Users can adjust the connector position based on the specific transport element being connected, providing flexibility while maintaining mischanneling prevention through the controlled adjustment mechanism.
Solution Approach 2:
The connector is divided into separable components including a movable element that can be independently adjusted. This segmentation allows the user to manipulate individual parts to achieve the correct connection configuration, enhancing user flexibility while maintaining safety through the structured adjustment process.

AI summary
An infusion set for a system for regulating the concentration of glucose in the blood of a person includes an infusion element having an infusion means for infusing a substance into a body of said person, and a transport element having a transport means for transporting the substance. The infusion element is adjustable from a neutral condition to at least a first or second condition, and in the first or second condition the infusion element is adapted to a first or second type of transport element only. A system for regulating the concentration of glucose in the blood of a person including two such infusion sets and to the use of such a system.
