Vacuum-Assisted Fat Collection Filter for Lipoinjection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conventional microlipoinjection process for fat transplantation is cumbersome, time-consuming, and inefficient due to clumsy instruments, high risk of fat cell damage, and contamination, especially during the washing and treatment of tissue, which complicates the separation of desired fat from unwanted materials.
Innovation Solution
A tissue collection vessel with a filter and vacuum system that allows for the separation of fat from additives and fluids within the vessel, reducing manual handling and contamination risks, and facilitating the preparation of fat for reinjection by using a collection bag and syringe system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional microlipoinjection process is used, then fat transplantation can be performed, but the process is cumbersome, time-consuming, and causes significant fat cell damage
Solution Approach 1:
The conventional multi-step process is segmented into a single integrated vacuum-assisted collection system where fat is directly separated from fluids through vacuum filtration during collection, eliminating the need for separate washing and processing steps
Solution Approach 2:
The collection, washing, and separation functions are merged into a single vacuum-assisted collection device that performs all operations simultaneously, reducing the number of steps from approximately 10 to just a few critical actions
2Productivity
If conventional instruments and techniques are used, then fat can be collected and transferred, but 50% or more of fat cells are damaged during the process
Solution Approach 1:
The manual mechanical transfer process using plunger syringes is replaced with a vacuum-assisted system that uses negative pressure to draw fat through a filter, eliminating the mechanical compression and forcing actions that damage fat cells
Solution Approach 2:
A porous filter is integrated into the collection device that allows fluids to pass through while retaining intact fat cells, providing automatic separation without mechanical manipulation that would damage the cells
3Productivity
If conventional multi-step process with separate centrifuging is used, then fat can be separated from fluids, but sterility is difficult to maintain and handling time increases
Solution Approach 1:
The collection and separation functions are merged into a single vacuum-assisted device that performs both operations simultaneously within a closed sterile system, eliminating the need for separate centrifuging steps that require leaving the sterile field
Solution Approach 2:
A disposable collection device with integrated filter acts as an intermediary between the sterile surgical field and the collection process, maintaining sterility while enabling efficient fat separation through vacuum-assisted filtration
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 solution streamlines the fat transplantation process by reducing tissue trauma, contamination risks, and handling time, improving the efficiency and success rate of fat graft 'take' through effective separation and preparation of fat for reinjection.

AI summary
A system in accordance with embodiments of the present invention includes a permeable tissue collection vessel or filter element disposed within a collection container. Collected tissue is deposited within the filter element through an inlet. Fluid that passes through the filter element is withdrawn from the collection canister through an outlet. An access port can be provided in a lid of the collection container to facilitate the removal of collected tissue from the tissue collection vessel.
