The patent application (Publication Number: US20240016830A1) describes a method for removing protein-based toxins, inflammatory mediators, and positively charged ions from physiological fluids using a biocompatible polymer system. The polymer system includes a polymer with pores and a sulfonic acid salt functionality. The method involves contacting the physiological fluid with this polymer system to achieve the desired removal.

The method outlined in the patent application specifies various aspects such as the molecular weight range of the toxins and inflammatory mediators, the pore structure of the polymer, and the biocompatibility of the polymer. Additionally, the application discusses the use of agents like heparin to enhance biocompatibility, the form of the polymer system (solid support), and the specific types of toxins and mediators targeted for removal. The application also details the production methods for the polymer, including polymerization techniques and the incorporation of sulfonic acid groups. Furthermore, the application mentions the potential housing of the polymer in containers for blood transfusion or in devices for extracorporeal circuits.
