Solution Overview

Problem

Current methods for processing adipose tissue, such as sedimentation, centrifugation, and filtration, are time-consuming, prone to contamination, and lack automation, especially due to the need for manual handling and open-space processing, which complicates the separation and purification of adipose tissue for lipofilling procedures.

Innovation Solution

A device comprising a container with an outlet duct and a separating float that allows for automated separation and suction of adipose tissue layers, including a container with a translucent design and a lid for easy handling, and a float that facilitates the separation and collection of the upper oil layer, enabling efficient separation and collection of adipose tissue layers without manual handling.
