Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current self-administration injection devices lack advanced digital capabilities, leading to concerns about incomplete medication delivery, needle safety, and user anxiety due to unfamiliarity with the devices, especially among those with little medical experience.
Innovation Solution
A resettable injection training device with a releasable locking outer housing, a slidable safety shield, and a plunger that simulates medication delivery, providing tactile and visual feedback to mimic the experience of using a needle without actual penetration, allowing for repeated practice and safe resetting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a needle-containing injection device is used for self-administration, then medication delivery is achieved, but user anxiety and fear increase due to unfamiliarity with the device and potential risks
Solution Approach 1:
The patent employs a training device that creates a realistic copy of the actual injection device, including the housing, plunger, and needle assembly. This copy allows users to practice the injection procedure repeatedly without the harmful effects of actual needle penetration, thereby reducing anxiety while maintaining operational familiarity
Solution Approach 2:
The training device serves as an intermediary between the user and the actual injection device. It provides tactile and visual feedback that mimics the real device's operation, allowing users to build confidence and competence before transitioning to actual medication administration
2Ease of operation
If a training device is used to reduce user anxiety, then familiarity with the injection process improves, but the device requires resetting capability for repeated practice
Solution Approach 1:
The training device is divided into separable components including the housing, plunger assembly, and needle assembly. The needle assembly can be detached and reattached, allowing the device to be reset for repeated practice sessions without requiring complete disassembly or complex resetting mechanisms
Solution Approach 2:
The needle assembly is designed to be easily removed and replaced, simulating the disposal of used needles while allowing the training device itself to be reused indefinitely. This approach simplifies the resetting process by focusing on component replacement rather than mechanical resetting
3Ease of operation
If the injection simulation member is extended for practice, then tactile feedback is provided, but safety concerns arise if the device is not properly reset
Solution Approach 1:
The needle assembly is extracted as a separate, removable component from the housing. This allows the sharp needle to be completely removed after training sessions, eliminating any risk of accidental contact while preserving the housing and plunger mechanisms for continued practice
Solution Approach 2:
The device incorporates a safety feature where the needle assembly must be properly reattached to the housing before the plunger can be operated. This preliminary check prevents accidental activation and ensures the device is in a safe state before each use
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 device reduces user anxiety and improves familiarity with the injection process, enhancing accuracy and safety by simulating the experience of medication delivery and needle use without actual skin penetration, thus addressing concerns about incomplete doses and needle safety.
Implementation Method 1
a biasing member disposed between the outer housing and the safety shield, said biasing member extends the shield in a proximal direction upon release of the locking tabs

AI summary
A resettable injection training device embodiment is provided. In one embodiment, the device may include an outer housing comprising locking tabs at its proximal end, a safety shield, the safety shield being slidable relative to the outer housing between a ready-to-fire position, and a fired position, wherein when the safety shield is in a fired position, the injection simulation member is retracted into the outer housing. The device may further include a plunger comprising a proximal end and a distal end, the proximal end comprising a plunger contact portion for interfacing with the locking tabs to displace the locking tabs to unlock the safety shield, and a biasing member disposed between the outer housing and the safety shield to extend the shield in a proximal direction upon release of the locking tabs, wherein retraction of the plunger and proximal movement of the outer housing resets the device.
