Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical training devices are limited to specific procedures and prioritize durability over realism, failing to provide a comprehensive and realistic simulation of human anatomy for a wide range of medical techniques, especially in the surgical field.
Innovation Solution
A multi-layered device with a skin-simulating outer layer, subcutaneous fat-simulating layer, fascia-simulating layer, and muscle-simulating layers, along with blood vessel-simulating tubes, made from specific silicone and polyurethane materials to mimic human anatomy and simulate realistic tissue behavior, allowing for a variety of medical procedures including vascular anastomoses creation and vascular access training.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a multi-layered structure with specific materials (silicone rubber, polyurethane foam) is used to improve realism of tissue simulation, then the realism and functionality for medical training is improved, but the durability and reusability deteriorate
Solution Approach 1:
The device is divided into multiple detachable layers (skin layer, subcutaneous fat layer, fascia layer, muscle layer) that can be separated and replaced independently. This segmentation allows the realistic multi-layered structure to be used for training while individual layers can be replaced when worn, balancing realism with durability through modular replacement rather than requiring the entire device to be durable and reusable.
Solution Approach 2:
The patent employs materials and layer structures that prioritize realistic simulation over long-term durability, accepting that these layers may be consumable or require replacement. The focus is on providing authentic training experience in the initial use, with the understanding that replacement layers can be used to maintain training quality without requiring the same level of long-term durability.
2Adaptability or versatility
If the device is designed for a wide range of medical procedures (vascular anastomoses, vascular access, etc.), then the versatility and adaptability is improved, but the device complexity increases
Solution Approach 1:
The device is designed with multiple layers and integrated blood vessel tubes that can support various surgical procedures including vascular anastomoses, vascular access, and other medical techniques. The multi-layered structure with embedded tubes serves multiple training functions simultaneously, allowing a single device to replace several specialized trainers while maintaining manageable complexity through unified design.
Solution Approach 2:
The blood vessel tubes are embedded within the multi-layered structure (nested within muscle layer, fascia layer, etc.), creating a compact integrated system. This nesting approach allows complex functionality (multiple procedures) to be achieved without proportionally increasing external complexity, as the tubes are contained within the existing layer structure rather than requiring separate components.
