Removable Cartridge Fluid Concentrator for Body Fraction Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical treatments face challenges in effectively concentrating and processing body fluids and tissues for therapeutic applications, particularly in achieving precise separation and concentration of desired fractions for various medical conditions and tissue regeneration.
Innovation Solution
A fluid concentrator system comprising a main housing and a removable cartridge with a separation chamber and ports, allowing for the extraction, separation, and concentration of body fluids and tissues, which can be further processed through filters or separation media within the cartridge to produce concentrated products for medical treatments and tissue culture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a batch process is used for concentration of body fluids, then separation and concentration of desired fractions can be achieved, but the device complexity and difficulty of operation increase due to manual handling and processing steps
Solution Approach 1:
The device is divided into modular components: a main body housing containing the separation chamber and a removable cartridge containing the concentration chamber with filter medium. This segmentation allows the complex separation-concentration process to be divided into distinct functional modules that can be independently optimized and easily replaced, reducing operational complexity while maintaining high separation precision.
Solution Approach 2:
The cartridge acts as an intermediary component between the separation chamber and the final concentrated product collection. It contains the filter medium and provides a controlled environment for concentration, mediating the transition from separated fractions to concentrated therapeutic products while simplifying the overall process control.
2Ease of operation
If a removable cartridge design is implemented, then ease of operation and cartridge replacement is improved, but the device complexity increases due to additional engagement mechanisms and sealing requirements
Solution Approach 1:
The removable cartridge design segments the concentration function from the separation function, allowing the cartridge to be easily removed and replaced. The cartridge includes integrated sealing elements and engagement features that simplify the replacement process while maintaining fluid-tight connections, reducing operational complexity despite the modular design.
Solution Approach 2:
The cartridge combines multiple functions into a single integrated component: it contains the concentration chamber, filter medium, sealing elements, and engagement mechanisms. This merging of functions into one replaceable unit simplifies operation by allowing users to replace a single component rather than managing multiple separate parts, despite the internal complexity of the cartridge design.

Function Achieved in This Case
Enables the production of concentrated body fluid fractions for diverse medical applications, including wound treatment and tissue regeneration, by selectively concentrating and filtering body fluids and tissues, thereby enhancing therapeutic efficacy and promoting healing.
Implementation Method 1
a separation chamber that is adapted to receive body fluid and to separate the body fluid into different fractions
Implementation Method 2
The selected fraction is passed through a material in the cartridge, such as a filter or separation medium, to form a concentrated product

AI summary
A fluid concentrator includes a main housing and a cartridge removably engaged to the main housing. The main housing includes a first end portion having a first port and a second port, an oppositely disposed second end portion and a separation chamber that extends between the first and second end portions. The second end portion has an inlet port and defines a cartridge passage that extends through the second end portion. The separation chamber is in fluid communication with the inlet port. The cartridge includes a first axial end portion that is engaged with the first end portion and an oppositely disposed second axial end portion, a portion of the second axial end portion is disposed in the cartridge passage of the second end portion of the main housing. The cartridge is adapted to filter fluid from the separation chamber.
