Resettable Injection Training Device Safety Shield Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Self-administration of injectable medications using existing devices is hindered by user anxiety, incomplete dosing, accidental needle sticks, and lack of familiarity, particularly among those with little medical experience, due to the intimidating nature and potential risks associated with these devices.
Innovation Solution
A resettable injection training device that simulates the injection process with a safety shield and plunger mechanism, allowing for repeated practice and ease of use, featuring a safety shield that moves between retracted, unlocked, and locked positions to ensure proper usage and prevent accidental device removal during training.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a real injection device with needle is used for training, then the training realism and effectiveness are improved, but the risk of accidental needle sticks and disease transmission increases
Solution Approach 1:
The patent creates a training device that is a safe copy of a real injection device. It includes an outer housing, safety shield, and plunger mechanism that replicates the appearance and operation of actual injection devices, allowing users to practice proper technique without using real needles or medications.
2Ease of operation
If a resettable training device is used, then the ease of operation and repeated practice are improved, but the device complexity increases
Solution Approach 1:
The training device incorporates dynamic components including a safety shield that can move between extended and retracted positions, and a plunger that can be depressed and reset. These dynamic elements allow the device to simulate real injection motions while maintaining the ability to be reset for repeated practice.
3Object-affected harmful factors
If a safety shield mechanism is added to prevent accidental removal, then the safety is improved, but the device complexity increases
Solution Approach 1:
The safety shield is designed to extend automatically to a locked position that prevents premature removal or accidental activation. This preliminary protective action ensures the device cannot be accidentally activated or removed before proper use, while the locking mechanism engages automatically without requiring additional user actions.

AI summary
A resettable injection training device for simulating an injection is provided in an embodiment herein. The device may include an outer housing, a safety shield having a proximal end and a distal end, the distal end for engaging with a target surface during an injection simulation, the safety shield comprising a retracted position, an extended unlocked position and an extended locked position, a plunger; and a locking tab for interfacing with the safety shield for interfacing with the safety shield the extended locked position, wherein if the safety shield distal end disengages from the target surface during an injection simulation, the safety shield extends to the extended, locked position until the device is reset.
