  • Hydrophilic membranes with a non-ionic surfactant
    Patent number: 8528744
    Abstract: The invention relates to hydrophilic membranes which are supplemented or treated with a non-ionic surfactant and processes for preparing such membranes. The membranes are particularly suitable for plasma separation or for haemodialysis and haemodiafiltration, but can also advantageously be used in other applications. Accordingly, the invention is further directed to the use of such membranes for plasma separation, plasma filtration, micro filtration, plasma therapy, haemodialysis and haemodiafiltration or cell filtration applications, respectively. The treated hydrophilic membranes show excellent biocompatibility, such as reduced platelet drop and decreased TAT levels.
