  • Stretch fabric substrate for medical use
    Patent number: 7207962
    Abstract: The present invention provides a stretch fabric substrate for medical use in a simple knitted structure with a good productivity having such a desired elastic recovery of elongation that no reduction of the fabric substrate in the widthwise direction takes place when elongation is applied to a necessary extent in the lengthwise direction. The fabric substrate according to the present invention is constituted by means of a warp knit substrate, the warp knit substrate is formed by means of a chain stitch using a stretch multifilament textured yarn and elastic yarns and non-stretch yarns are inserted in the lengthwise direct ion and in the widthwise direction, respectively to the chain stitch.
    Type: Grant

  • Apparatus for exchanging substances
    Patent number: 5395525
    Abstract: An apparatus for exchanging substances, such as artificial lung, in which, for raising exchange efficiency by feeding liquid to the outer wall of hollow fiber membranes efficiently without channeling and for reducing the size of the apparatus, an exchanging part comprising a multitude of hollow fiber membrane (3) disposed cylindrically or annularly to permit liquid to flow through the hollow parts is provided, and a pump (P) is disposed on the inner periphery of said exchanging part so that liquid may continuously be fed to the hollow membrane vertically with respect to the axial direction of said hollow fiber membrane (3).
