Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical training devices lack realistic simulations of natural human tissue, limiting the effectiveness of training for medical procedures such as injections, surgeries, and wound management.
Innovation Solution
Development of multi-layer tissue inserts and models that accurately mimic human anatomy, including skin, subcutaneous, fascia, and muscle layers, using a combination of platinum-cured silicone thermosets and other materials to provide realistic tactile feedback and resistance, which can be used with existing manikins or incorporated into new training systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If earlier attempts to mimic human tissue using two-component silicone gels and nylon fabric are used, then basic tissue simulation is achieved, but realistic tactile feedback and anatomical accuracy are inadequate
Solution Approach 1:
The tissue model is divided into multiple distinct layers including skin layer, subcutaneous layer, fascia layer, and muscle layer, each made from materials with different physical properties to accurately represent the unique characteristics of each anatomical layer
Solution Approach 2:
The patent uses composite materials consisting of platinum-cured silicone thermoset blended with various additives including silicone oil, silicone foam, pigments, and other compounds to create materials that simultaneously provide anatomical accuracy, realistic tactile feedback, and appropriate mechanical properties for each tissue layer
2Manufacturing precision
If multi-layer tissue inserts with complex material compositions are developed, then realistic tactile feedback and anatomical accuracy are improved, but manufacturing complexity increases
Solution Approach 1:
The patent adjusts material parameters such as shore hardness, viscosity, and composition ratios to achieve the desired balance between anatomical accuracy and manufacturing feasibility, using specific ranges for blend ratios and additive concentrations
Solution Approach 2:
The patent incorporates additives and pigments into the base silicone materials during the mixing stage before molding, pre-preparing the multi-component material compositions to simplify the overall manufacturing process and ensure uniform distribution of properties throughout each tissue layer
