Problem
Existing wearable injection devices face limitations in delivering highly viscous medicaments, require manual filling, are costly, and users lack confidence in self-administering injections due to needle anxiety and incorrect placement, leading to noncompliance with therapeutic regimens.
Innovation Solution
A resettable injection training device with a housing, removable container, actuation member, and sensors that simulate injection, providing feedback and ensuring correct placement and operation, allowing for safe and effective practice.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wearable patch pumps are used for subcutaneous delivery, then delivery control is improved, but device complexity and cost increase due to manual filling requirements
Solution Approach 1:
The patent creates a training device that replicates the appearance, structure, and operation of actual medicament delivery devices without containing real medicament. This copy allows users to practice proper technique, device handling, and injection procedures safely, reducing the complexity burden by eliminating the need for manual filling while maintaining operational training value
Solution Approach 2:
The training device is designed as a disposable or resettable tool that does not require expensive medicament reservoirs or complex filling mechanisms. By using simple, replaceable components rather than permanent expensive systems, the device maintains ease of operation for learning while reducing overall system complexity and cost
2Ease of manufacture
If auto injection devices are used, then cost and ease of use are improved, but therapeutic delivery capability is limited for highly viscous medicaments
Solution Approach 1:
The training device replicates various types of injection devices including auto-injectors and wearable pumps in a single platform. By creating accurate copies of different device types, it allows users to practice with cost-effective auto-injector designs while also preparing them for versatile therapeutic deliveries including highly viscous medicaments that may require different device types
Solution Approach 2:
The training device serves multiple functions: it can simulate auto-injectors, wearable patch pumps, and other injection devices. This multi-functionality allows a single cost-effective training tool to prepare users for various therapeutic delivery scenarios, including those involving highly viscous medicaments that auto-injectors cannot handle, thereby expanding adaptability without increasing cost
3Productivity
If rapid injection is performed with high viscosity compound, then injection time is reduced, but tissue distension and pain increase
Solution Approach 1:
The training device includes simulation elements that replicate the sensation and visual feedback of proper injection technique. By copying the experience of correct slow injection for viscous materials, users learn to control injection speed to avoid tissue distension and pain, while still achieving productive delivery through proper technique rather than rapid injection
