Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for practicing hypodermic needle insertion techniques lack effective visualization of anatomical landmarks, which can lead to inaccuracies in needle placement during training and actual procedures.
Innovation Solution
A kit and method utilizing a deformable needle receiving object with anatomical landmark indicia and needle insertion site indicia, such as a template, to guide proper needle insertion, including a pierceable housing and aids like templates with raised borders to simulate tissue manipulation and muscle bulging, facilitating accurate needle placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional practice methods (oranges, grapefruits, or simple pads) are used for needle insertion training, then the training can be performed, but the anatomical landmark visualization is insufficient leading to inaccurate needle placement
Solution Approach 1:
The patent creates a simplified copy of human anatomy through the anatomical model with surface features representing skin, subcutaneous tissue, and muscle layers. This copy includes printed anatomical landmarks and injection site indicators that replicate real anatomical references, allowing trainees to practice needle insertion with proper landmark visualization without using actual human subjects.
Solution Approach 2:
The patent employs color-coded indicators to differentiate various anatomical structures and injection sites. The anatomical model uses distinct colors for skin, subcutaneous tissue, and muscle layers, with specifically colored indicators marking safe injection zones and anatomical landmarks, enhancing visual discrimination and accuracy for trainees.
2Measurement precision
If real human subjects are used for needle insertion practice, then anatomical accuracy is maintained, but ethical concerns and safety risks arise
Solution Approach 1:
The patent creates a simplified copy of human anatomy through the anatomical model with surface features representing skin, subcutaneous tissue, and muscle layers. This copy includes printed anatomical landmarks and injection site indicators that replicate real anatomical references, allowing trainees to practice needle insertion with proper landmark visualization without using actual human subjects.
Solution Approach 2:
The anatomical model is designed as a disposable, low-cost training aid that can be discarded after use. This eliminates the need for repeated use on the same model, ensuring hygiene and preventing contamination risks while providing unlimited practice opportunities through multiple single-use models.
3Measurement precision
If detailed anatomical models are created to improve landmark visualization, then needle placement accuracy improves, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The anatomical model is segmented into distinct functional layers (skin, subcutaneous tissue, muscle) represented by different materials and colors. This segmentation allows each layer to be optimized independently for its specific function while maintaining overall simplicity in the manufacturing process.
Solution Approach 2:
The patent uses parameter changes in material properties (firmness, color, texture) to differentiate anatomical layers without adding structural complexity. The skin layer uses a softer material, while muscle layers use firmer materials, and color variations provide visual differentiation, all achievable through standard manufacturing techniques.
