Syringe-Based Aesthetic Treatment Simulation With Diverted Fluid Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing simulation systems for aesthetic medicine treatments require complex structures to collect injected liquids, leading to durability issues and high costs, or use non-puncturable dummies that lack realism and effective training.
Innovation Solution
A simulation system with a synthetic anatomical structure and a syringe that diverts fluid flow externally, using a needle isolated from the syringe cavity, combined with a cam to simulate viscosity and a display for real-time feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a puncturable dummy is used to simulate fluid injection, then training realism is improved, but durability deteriorates due to repeated punctures and fluid exposure
Solution Approach 1:
The patent uses a synthetic anatomical structure that copies the essential training function of a puncturable dummy (allowing needle insertion and fluid injection simulation) while using durable materials that resist degradation from repeated use and fluid exposure, thus maintaining training realism without sacrificing durability
Solution Approach 2:
The synthetic anatomical structure employs a flexible outer layer that can be punctured by needles like real tissue, providing realistic training feedback, while the underlying structure maintains integrity and durability through repeated puncture cycles and fluid exposure
2Object-generated harmful factors
If a collection system is added to the dummy to recover injected fluid, then fluid leakage is prevented, but device complexity increases
Solution Approach 1:
The patent introduces a fluid collection system with reservoirs and conduits that act as intermediaries to capture and contain injected fluid, preventing leakage while maintaining a relatively simple overall system architecture that integrates smoothly with the synthetic anatomical structure
3Reliability
If the needle is fluidically connected to the syringe cavity, then fluid injection realism is improved, but fluid leakage and contamination risks increase
Solution Approach 1:
The patent segments the fluid pathway by introducing a valve mechanism that separates the needle from the syringe cavity, allowing the needle to be fluidically connected during injection for realism while preventing leakage and contamination when the valve is closed
Solution Approach 2:
The patent employs a dynamic valve system that can switch between open and closed states, providing fluidic connection between needle and syringe cavity during injection for realism, and disconnecting them afterward to prevent leakage and contamination
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system maintains durability and realism by simulating fluid injection and aspiration without internal fluid exposure, providing realistic training with durable and cost-effective simulations.
Implementation Method 1
the cam (15a) is capable of at least partially compressing and throttling a pipe that is at least partly compressible of the connection means (9), in such a way as to modify the resistance provided by the pipe to the flow and simulate different viscosities of the injected or aspirated fluid
