Liposuction Fat Separation System and Gravity Aliquot Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current liposuction procedures, such as water-jet liposuction, result in fat being aspirated with water, making it difficult to handle and inject safely and practically, as the fat is not isolated from contaminants during processing and injection.
Innovation Solution
A closed system comprising taking means, separation syringes arranged vertically to separate fat from aqueous fluids by gravity, and connection means to manage the separation and storage of fat in sealed aliquots, ensuring isolation from contaminants throughout the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If fat is aspirated with water during liposuction, then the fat can be easily removed from subcutaneous tissue, but the fat becomes mixed with water and contaminants making it difficult to handle and inject
Solution Approach 1:
The system divides the mixed adipose material into separate components using vertical separation syringes where fat and water naturally separate by gravity. The fat rises to the top while water settles at the bottom, allowing selective extraction of pure fat aliquots for injection while discarding the water layer.
Solution Approach 2:
The closed system acts as an intermediary between the liposuction aspiration and the final injection process. It provides a controlled environment where separation occurs without exposure to external contaminants, and enables precise aliquoting of fat for subsequent medical procedures.
2Ease of operation
If the container is opened to take doses of fat with a syringe, then the fat can be accessed for injection, but the fat is exposed to contaminants from the outside environment
Solution Approach 1:
The system maintains a closed, sterile environment throughout the entire process of fat separation and aliquoting. The separation syringes and collection vials remain sealed until the moment of use, creating an inert atmosphere that prevents contamination from external sources while still allowing controlled access to the fat for injection.
Solution Approach 2:
The system performs preliminary separation of fat from water and contaminants before the injection process begins. By pre-separating the adipose material into pure fat aliquots in a closed system, it eliminates the need to open the container during dose preparation, thus preventing contamination while maintaining accessibility.
3Device complexity
If fat and water are mixed in the same container, then the aspiration process is simple, but the subsequent separation and dosing becomes complex and impractical
Solution Approach 1:
The system uses vertically oriented separation syringes that automatically segment the mixed fat-water mixture into distinct layers based on density. Fat rises to the upper portion while water settles at the bottom, enabling easy extraction of pure fat doses without complex separation equipment or procedures.
Solution Approach 2:
The separation process occurs automatically through gravity acting on the vertical syringes, requiring no active intervention or complex mechanical separation devices. The system self-separates the mixture, making the dosing process simple and practical while maintaining sterility.
