    摘要: A production method for a medical instrument includes a plurality of integrated hollow fiber membrane producing a base material forming a cylindrically-shaped body. Each of the hollow fiber membranes sequentially passes through a first point, a second point, a third point, a fourth point, and a fifth point that are set on a core member. In an outward path heading toward the third point from the second point, the hollow fiber membrane reaches the third point from the second point at the shortest distance while being wound in the circumferential direction of the core member. Moreover, in a homeward path heading toward the fifth point from the fourth point, the hollow fiber membrane reaches the fifth point from the fourth point at the shortest distance while being wound in the circumferential direction of the core member in the same direction as in the case of the outward path.

    摘要: An oxygenator includes a housing; a hollow fiber membrane layer that is stored in the housing and has multiple integrated hollow fiber membranes with a gas exchange function; a gas inlet portion and a gas outlet portion that are provided on the upstream and downstream of gas passages in lumens of the hollow fiber membranes, respectively; and a blood inlet portion and a blood outlet portion that are provided on the upstream and downstream of blood passages outsides of the hollow fiber membranes, respectively. The hollow fiber membranes in the hollow fiber membrane layer are fixed relative to each other at one end portion and the other end portion thereof. Conditions 30≦ε60 and OD≦4.5×ε are met where ε [μm] is an average separation distance between the adjacent hollow fiber membranes at a fixed portion of the hollow fiber membrane layer and OD [μm] is the outer diameter of the hollow fiber membrane.

    摘要: An Oxygenator as a medical instrument includes at least one first hollow fiber membrane layer comprised of a plurality of integrated first hollow fiber membranes, and forms a shape of a cylindrical body as a whole, and at least one second hollow fiber membrane layer disposed at the outer circumferential side of the first hollow fiber membrane layer in a state of being concentric with the first hollow fiber membrane layer, has a plurality of integrated second hollow fiber membranes, and forms a shape of a cylindrical body as a whole. Moreover, each of the first hollow fiber membranes is wound around a central axis, and each of the second hollow fiber membranes is wound around a central axis. The number of times the second hollow fiber membranes are wound is smaller than the number of times the first hollow fiber membranes are wound.
