DIALYZER COMPRISING BUNDLE OF HOLLOW FIBERS AND METHOD FOR PRODUCING SUCH HOLLOW FIBERS

摘要

PROBLEM TO BE SOLVED: To provide a dialyzer comprising a bundle of hollow fibers and a method for producing such hollow fibers.SOLUTION: The present invention relates to a dialysis membrane and a hollow fiber as pre-product as well as a method for producing the hollow fiber. The dialysis membrane according to the present invention includes a distribution of the pore sizes which follows an exponential function, in particular an e-function. The inverse value of the exponential coefficient (K) of the e-function is at least 30 nm, in particular 80 nm. The dialysis membrane includes at least 50 pores per μmand the share of an effective flow area at a surface of the dialysis membrane amounts to at least 2.5%.
