| titleOfInvention | Hollow fiber membrane for use in an anesthetic circuit |
| abstract | Hydrophobic poly(4-methyl-1-pentene) hollow fiber membrane for retention of anesthetic agents with an inner and an outer surface and between inner and outer surface an essentially isotropic support layer with a sponge-like, open-pored, microporous structure free of macrovoids and adjacent to this support layer on the outer surface a dense separation layer with a thickness between 1.0 and 3.5 µm. The membrane has a porosity in the range of greater than 35% to less than 50% by volume and a permeance for CO 2 of 20-60 mol/(h·m 2 ·bar), a gas separation factor α(CO 2 /N 2 ) of at least 5 and a selectivity CO 2 / anesthetic agents of at least 150. n The process for producing this membrane is based on a thermally induced phase separation process in which process a homogeneous solution of a poly(4-methyl-1-pentene) in a solvent system containing compounds A and B is formed, wherein compound A is a strong solvent and compound B a weak non-solvent for the polymer component. After formation of a hollow fiber the hollow fiber is cooled in a liquid cooling medium to form a hollow fiber membrane. The concentration of the polymer component in the solution may be between 42.5- and 45.8 wt.-% and the hollow fiber leaving the die runs through a gap between die and cooling medium with a gap length in the range of 5-30 mm. |
