Integrated Infusion Catheter and CGM Assembly for Single Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insulin pumps require separate insertion of infusion catheters and CGM sensors, which is cumbersome and increases the number of needle sticks and application steps for users.
Innovation Solution
A cartridge assembly with an integrated infusion catheter and CGM sensor subassembly that can be deployed together through a single insertion using an introducer needle, minimizing the number of insertion steps and reducing discomfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate insertion of infusion catheter and CGM sensor is used, then each component can be inserted independently, but the number of needle sticks and application steps increases
Solution Approach 1:
The patent combines the infusion catheter and CGM sensor into a single integrated subassembly that is inserted through one needle stick. The carrier holds both components in aligned positions, allowing simultaneous insertion into the tissue through a single puncture, thereby reducing the number of application steps while maintaining functional independence of each component
Solution Approach 2:
The carrier serves multiple functions: it holds the infusion catheter, positions the CGM sensor, guides both components through the tissue during insertion, and can be removed after deployment. This multi-functional design enables a single device to accomplish what previously required separate insertion procedures
2Object-affected harmful factors
If multiple separate devices are used for infusion and CGM, then each device can be optimized independently, but the number of needle sticks increases causing more discomfort
Solution Approach 1:
By merging the infusion catheter and CGM sensor into one insertable unit, the patent reduces the number of needle sticks from two separate procedures to one single insertion, directly reducing user discomfort and trauma while the integrated design manages the complexity of coordinating both functions
3Productivity
If separate insertion procedures are used, then each component can be inserted with optimal positioning, but the application time increases
Solution Approach 1:
The carrier is pre-configured with the infusion catheter and CGM sensor in their correct relative positions before insertion. This preliminary arrangement eliminates the need for separate positioning steps during the procedure, allowing both components to be inserted simultaneously in a single action, thereby increasing application speed
