A medical tube clamp wherein first and second plate parts including, on opposing surfaces, compressive protrusions for closing a medical tube are provided with a pair of side walls on both sides projecting from one toward an other of the plate parts, and are also provided with a central guide protrusion projecting from the other toward the one of the plate parts. Both sides of a tip portion of the central guide protrusion make sloping guide surfaces projecting toward a center. When the plate parts are displaced relative to each other so as to become closer, lateral displacement of them is corrected by a slide of the pair of side walls and the sloping guide surfaces, and the central guide protrusion is inserted between the pair of side walls.

There is provided a protective filterfor an extracorporeal circulation circuit pressure monitor, having a dialysis device side housing, an extracorporeal circulation circuit side housing, and a hydrophobic filterheld between both the housings, which allows passage of a gas but does not allow passage of a liquid, characterized in that a plurality of ribsandcapable of supporting the hydrophobic filterare respectively provided in both housings, and a protective memberfor preventing direct contact between the ribsand the hydrophobic filteris interposed between the ribsprovided in the extracorporeal circulation circuit side housingand the hydrophobic filter

Protective filter for extracorporeal circulation circuit pressure monitor

A dialyzer in which a nearly cylindrical case is provided therein with a hollow fiber bundle made of a plurality of hollow fiber membranes, a blood flow path formed by lumens of the hollow fiber membranes, a dialyzate flow path formed by a space between the inner wall of the case and the hollow fiber membranes and a cylindrical heat-shrinkable tube provided on the outside of the hollow fiber bundle and at least a part of which can be shrunk by heating, and a method for manufacturing the dialyzer.
