Human Body Simulation Device with Dynamic Heart and Vessel Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current human body simulation systems lack the capability to simulate procedures for the heart, such as percutaneous coronary intervention (PCI) for coronary ischemic heart disease, and do not effectively model minimally invasive treatments or inspections using medical devices like catheters.
Innovation Solution
A human body simulation device comprising a heart model, blood vessel model, pulsation mechanism, and control system that mimics heart and blood vessel dynamics, allowing for adjustable heart and pulsation rates, and simulates both normal and arrhythmic states, with input options for users to set heart rates and display changes in heart rate for a more realistic simulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a simulation system includes only an aorta model, then the system structure is simple, but the system cannot simulate treatment or inspection procedures for the heart
Solution Approach 1:
The simulation system integrates multiple biological models (aorta model, heart model, blood vessel models) into a single unified system that can perform multiple simulation functions including aortic procedures, cardiac procedures, and coronary interventions, allowing one system to serve multiple medical training purposes
Solution Approach 2:
The heart model is nested within the aorta model structure, with the heart model containing internal chambers and valves, while the aorta model provides the external vascular framework, creating a hierarchical nested structure that enables comprehensive cardiac simulation
2Reliability
If the control portion changes beat rate and pulsation rate depending on prescribed heart rate, then the simulation realism is improved, but the device complexity increases
Solution Approach 1:
The control portion dynamically adjusts the beat rate of the heart model and pulsation rate of the aorta model based on prescribed heart rate values, transforming static simulation parameters into dynamic, adaptable variables that respond to different physiological conditions
Solution Approach 2:
The control portion receives prescribed heart rate information as input and uses this feedback to automatically regulate the beating motion of the heart model and the pulsation of the aorta model, creating a closed-loop control system that maintains physiological accuracy

AI summary
A human body simulation device includes a heart model simulating a heart, a beat portion for causing the heart model to beat, a blood vessel model simulating a blood vessel, a pulsation portion for sending a pulsated fluid into the blood vessel model, and a control portion for changing a beat rate of the beat portion and a pulsation rate of the pulsation portion depending on a prescribed heart rate.
