Activated Carbon Fiber Oral Adsorbent for Uremic Toxin Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current orally administered adsorbents for uremic toxins, such as those comprising spherical activated carbon, have insufficient adsorption performance and require high daily doses, leading to gastrointestinal symptoms and inefficacy in rapidly reducing harmful substances in the body, particularly in patients with chronic kidney disease.
Innovation Solution
Activated carbon fibers (ACFs) with specific properties, including high specific surface area, uniform diameter, and controlled fiber length, are used for oral administration to enhance adsorption performance and selective adsorptivity, allowing for rapid and effective removal of uremic toxins while minimizing adsorption of essential high-molecular-weight compounds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spherical activated carbon is used as an orally administered adsorbent, then the adsorbent can be administered orally to remove uremic toxins, but the adsorption performance is insufficient requiring high daily doses which causes gastrointestinal symptoms
Solution Approach 1:
The patent employs activated carbon fibers with a highly developed porous structure and large specific surface area to enhance adsorption performance. The porous material captures uremic toxins more effectively, allowing lower dosages that avoid gastrointestinal side effects while maintaining therapeutic efficacy.
Solution Approach 2:
The invention changes the physical and chemical parameters of the carbon adsorbent by using activated carbon fibers instead of spherical activated carbon. This includes optimizing the specific surface area, pore volume, and surface chemistry to achieve superior adsorption capacity and selectivity for uremic toxins at lower doses.
2Reliability
If high daily doses of spherical activated carbon are administered to achieve sufficient adsorption, then uremic toxin removal is improved, but the treatment imposes great strain on patients with chronic kidney disease
Solution Approach 1:
Activated carbon fibers provide a larger effective surface area per unit mass compared to spherical activated carbon, enhancing the adsorption capacity. This allows the same therapeutic effect to be achieved with lower doses, reducing the burden on patients who must control their fluid intake.
Solution Approach 2:
The patent develops composite formulations incorporating activated carbon fibers with specific functional groups that enhance selectivity for uremic toxins. This composite approach improves toxin removal efficiency at lower doses, thereby reducing patient burden.
3Productivity
If spherical activated carbon adsorbents are used, then intestinal adsorption and excretion of uremic toxins can be achieved, but the adsorption performance is insufficient requiring high doses
Solution Approach 1:
The activated carbon fibers possess a highly developed porous structure with large specific surface area and appropriate pore size distribution, which dramatically enhances the adsorption rate and capacity for uremic toxins. This allows faster and more efficient toxin removal at lower doses.
Solution Approach 2:
The invention optimizes key parameters including specific surface area, total pore volume, micropore volume, and surface functional groups of the activated carbon fibers to maximize adsorption kinetics and capacity, achieving high productivity with reduced material quantity.
