Handle for catheters

The present invention provides a medical material and a blood purification apparatus each having high anti-thrombotic properties and high safety. The apparatus is produced by incorporating therein a medical material which has a hydrophilic copolymerization polymer present on a surface thereof which is to be in contact with blood, wherein particulate protuberances each having a particle diameter of 50 nm or more are present on the surface which is to be in contact with blood at a density of 3 particles/&#x3bc;mor less and the relaxation time of adsorbed water in the hydrophilic copolymerization polymer is 2.5&#xd7;10seconds or shorter and 5.0&#xd7;10seconds or longer at &#x2212;40&#xb0; C.

Medical material and hollow fiber membrane module

A take-up apparatus for tape type non-twisted carbon fiber bundles, in which a traverse guide unit consists of an introduction guide roller disposed so that an angle .theta..sub.1 between the introduction guide roller and the axial direction of the bobbin is substantially 90.degree., a final guide roller disposed so that an angle .theta..sub.e between it and the axial direction of the bobbin is -5.degree..+-.10.degree.(i.e., -15.degree. to +5.degree.), and at least one intermediate guide roller disposed between the introduction guide roller and final guide roller so that an angle difference between an intermediate guide roller and an adjacent guide roller is not more than 45.degree.. A take-up apparatus is also disclosed for tape type non-twisted carbon fiber bundles, in which a traverse guide unit has a helically continuing curved guide surface, an initial portion, i.e. an introduction surface portion of the curved guide surface extending at substantially right angles to the axial direction of a bobbin, and a final portion, i.e. discharge surface portion of the curved guide surface extending at an angle in the range of -5.degree..+-.10.degree. with respect to the axial direction of the bobbin.
