Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional medical training methods lack the ability to visualize and monitor the placement of medical devices inserted into or around the heart, as well as the impact on blood flow patterns and velocities, posing a risk of adverse complications during procedures.
Innovation Solution
A simulator system with a removable chest plate, fluid reservoirs, pumps, and translucent atrium allows for the visualization of medical device placement and blood flow patterns, simulating the insertion of devices via cannulation into a model of the heart, using pulsatile flow paths and anatomically correct structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional training methods are used for teaching medical procedures involving remote placement of medical devices, then the training can be conducted without specialized equipment, but the ability to visualize and monitor device placement and blood flow patterns is lost, leading to inability to detect placement errors
Solution Approach 1:
The patent creates a physical model copy of the heart and vasculature that replicates anatomical structures. This model allows visualization of device placement without requiring actual patient procedures, solving the contradiction by providing measurement capability through a simplified replica rather than complex real-time monitoring of actual procedures
Solution Approach 2:
The patent introduces an intermediary visualization system that includes transparent or translucent sections of the model, markers, and visual indicators. This intermediary allows observers to see device placement and blood flow patterns without directly interfering with the procedure, providing measurement capability while keeping the training system relatively simple
2Reliability
If traditional training methods are used without visualization capabilities, then the training system remains simple and inexpensive, but adverse complications cannot be detected or monitored during procedures
Solution Approach 1:
The patent uses color-coded components within the model, such as colored blood substitutes or colored device sections, to indicate proper versus improper placement. This visual differentiation provides reliable error detection through simple color observation rather than complex monitoring equipment
Solution Approach 2:
The patent incorporates visual parameters such as transparency, color, and visual markers that change or differ based on device placement quality. These parameter changes provide immediate feedback on placement accuracy, enabling reliable error detection through observation rather than complex instrumentation
3Adaptability or versatility
If realistic simulation of heart procedures is provided with visualization of blood flow patterns, then training effectiveness is improved, but the system complexity and cost increase significantly
Solution Approach 1:
The patent divides the heart model into segmented sections with different levels of transparency or visibility. Critical areas where device placement matters most are made transparent or include visual indicators, while other areas maintain realistic appearance. This segmentation provides realistic simulation where needed without requiring the entire system to be overly complex
Solution Approach 2:
The patent designs the model to serve multiple training purposes simultaneously - it can be used for teaching anatomy, practicing device insertion, visualizing blood flow patterns, and detecting placement errors all in one system. This multi-functionality increases adaptability while distributing the complexity across various usable features rather than requiring separate specialized systems

AI summary
Systems and methods for simulating the insertion of a device via cannulation include an external shell which is at least partially filled with a silicone material, a simulated venous flow path, a simulated arterial flow path, one or more pumps to provide fluid to these flow paths, and a visible atrium in fluid communication with the venous flow path. The venous and arterial flow paths are made of flexible and distensible tubing, which is at least partially embedded within the silicone material in cannulation regions, and which is configured to be pierced to allow for insertion of a device therein. The atrium comprises a translucent front wall to enable, before, during, or after insertion of the device, visible inspection inside of the atrium.
