Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adipose tissue processing devices lack features to prevent overflow, minimize filter clogging, and ensure sterility during tissue extraction, leading to inefficiencies and potential contamination in autologous fat transfer procedures.
Innovation Solution
A tissue processing system with a container having a filter structure, flow management device, and a flexible outlet with a stop mechanism to prevent overfilling, along with a design that includes a valve to control fluid levels and a configuration that prevents leakage during tissue extraction, and mixing blades that unclog filter pores to enhance processing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid outlet port is used in existing tissue processing devices, then the device structure is simple, but the distal opening leaks during tissue extraction and requires manipulation during syringe changes
Solution Approach 1:
The outlet port is constructed with a flexible distal portion that can conform to syringe openings and maintain seals during manipulation. This flexible structure prevents leakage while accommodating the dynamic movements required during tissue extraction and syringe changes, eliminating the need for complex manipulation procedures.
2Productivity
If the filter structure has small pore size to maximize tissue processing volume, then more tissue can be processed, but the filter pores clog more easily
Solution Approach 1:
The filter structure incorporates movable components that can shift or expand to prevent clogging. The dynamic design allows the filter to adapt to varying tissue flow conditions, maintaining open pores even when processing high volumes of tissue, thus preventing clogs while maximizing processing capacity.
Solution Approach 2:
The filter pore size or configuration can change during operation to optimize performance. When clogging is detected or anticipated, the system adjusts filter parameters such as pore opening size or flow distribution to maintain tissue processing volume while preventing pore blockage.
3Device complexity
If no stop mechanism is added to existing devices, then the device structure is simpler, but the fluid fill level must be manually monitored to prevent overflow
Solution Approach 1:
The stop mechanism is designed to automatically prevent overflow without requiring user intervention or monitoring. The device self-regulates fluid fill level by stopping inflow when the maximum level is reached, eliminating the need for manual monitoring while adding minimal structural complexity.
4Device complexity
If the outlet port requires manipulation during tissue extraction, then the device structure can be simpler, but fat leakage occurs and sterility may be compromised
Solution Approach 1:
The flexible outlet port maintains continuous contact with the syringe opening through its ability to deform and conform, creating a consistent seal that prevents fat leakage and maintains sterility without requiring manual manipulation or repositioning during tissue extraction.
