Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical systems combining infusion and sensing functions are difficult to manufacture and handle, particularly for patients with diabetes, requiring a simpler and more reliable apparatus for insulin delivery and glucose monitoring.
Innovation Solution
A medical apparatus with a biocompatible casing, a flexible cannula, and a sensor system integrated with a single seal mechanism that allows for easy insertion and withdrawal of the insertion needle, ensuring reliable sealing and minimizing the number of piercing locations, facilitating simultaneous insulin infusion and glucose detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a medical system combines infusion and sensor sections using separate piercing members, then the system can perform both infusion and detection functions, but the system becomes difficult to manufacture and handle
Solution Approach 1:
The patent merges the infusion cannula and sensor into a single integrated assembly that is inserted through a single piercing location. The cannula and sensor are combined in one housing structure, eliminating the need for separate piercing members and reducing the overall complexity of the device while maintaining both infusion and detection capabilities
Solution Approach 2:
The single insertion needle serves multiple functions: it acts as both the infusion delivery vehicle and the sensor insertion vehicle. The housing structure is designed to accommodate both the cannula for infusion and the sensor for detection, allowing one piercing location to serve dual purposes for both fluid delivery and substance measurement
2Reliability
If multiple separate piercing members are used for infusion and sensor sections, then each component can be optimized independently, but the number of piercing locations increases causing more discomfort
Solution Approach 1:
The patent combines the infusion cannula and sensor into a single integrated assembly that is inserted through a single piercing location. The cannula and sensor are combined in one housing structure, eliminating the need for separate piercing members and reducing the overall complexity of the device while maintaining both infusion and detection capabilities
Solution Approach 2:
The insertion assembly is segmented into distinct functional components (cannula, sensor, housing) that can be independently optimized and manufactured, while being assembled into a single unit for insertion. This allows component optimization without requiring multiple separate piercing operations
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus simplifies the construction and handling of the medical system, providing reliable insulin delivery and glucose monitoring, reducing discomfort and manufacturing costs, while ensuring accurate blood glucose control for diabetic patients.
Implementation Method 1
a seal (in particular comprising a deformable material, in particular comprising a flexible material, in particular located at the opening or close to the opening) adapted to annularly sealingly surround the insertion needle, when the insertion needle is arranged in the opening
Implementation Method 2
a sensor system (in particular comprising a detection portion for detecting the substance, and a supply portion or a cable portion for conducting sensor signals indicative of the substance and/or for supplying the sensor system with electric energy and/or a control signal) for detecting the substance of the organism
Implementation Method 3
a cannula (being in particular of a tubular shape, being in particular manufactured from a flexible material such as plastic, the cannula in particular providing a flexible tube or tubular structure having in particular an outer mantel having a circular or oval cross-sectional shape and enclosing the lumen) having a lumen (providing a space through which the medication fluid can be transported) being in fluid communication with the chamber
