Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current injection training methods lack standardization and uniformity, leading to inadequate training and certification of injectors, resulting in variable expertise and increased risks of complications such as chronic pain, bruising, and irreversible damage due to limited access to diverse anatomical models and internal organ training simulations.
Innovation Solution
The development of injection training systems that utilize a needle with a fluorescent tip emitting omnidirectional light, allowing for precise detection of needle position through sensors, enabling improved training and certification in artificial injection sites, such as artificial faces, to assess skill levels and provide real-time feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If classroom-based training with live models is used, then hands-on practice is provided, but the availability and diversity of training models are limited
Solution Approach 1:
The patent creates artificial injection sites that are copies or replicas of real human anatomical structures. These artificial models replicate skin layers, subcutaneous tissue, and internal organs, allowing trainees to practice on realistic replicas without the limitations of live models. The artificial face model includes layered structures mimicking human anatomy, providing versatile training opportunities.
Solution Approach 2:
The patent employs fluorescent materials and light-emitting components that change the optical parameters of the training model. The fluorescent tip on the needle and fluorescent markers in the artificial site enable detection and tracking of needle position through fluorescence imaging, transforming the training system into an interactive, feedback-providing platform that overcomes the limitations of static live models.
2Measurement precision
If fluorescent material is added to the needle tip, then light emission for detection is improved, but the complexity of the testing tool increases
Solution Approach 1:
The patent utilizes fluorescent materials that emit light at different wavelengths when excited. The needle tip contains fluorescent material that absorbs light at one wavelength and emits at another, creating a detectable signal for position tracking. This optical property change enables precise detection without requiring complex mechanical or electronic modifications to the needle itself.
Solution Approach 2:
The patent introduces fluorescent material as an intermediary substance between the needle and the detection system. Rather than making the needle itself complex with embedded sensors, the fluorescent coating acts as a mediator that converts the needle's position into detectable light signals, simplifying the overall system architecture while maintaining high measurement precision.

AI summary
Systems, methods, and apparatuses for providing substantially omnidirectional light emission from a tip of a needle for use with injection training systems are provided. The substantially omnidirectional light emission improves the angular range of detection of the emitted light. The approach uses principles of fluorescence and/or light diffusion to emit light in a substantially omnidirectional pattern from the needle tip in order to improve the detectability of the emitted light by a light detector.
