摘要:
The present invention relates to a hollow fiber membrane made of two coextruded layers A and B, wherein layer B has a non-woven type structure having a mesh size of 0.1 to 10 μm and layer A has a porous structure. The present invention further relates to a method for producing a membrane according to the invention and the use thereof.
摘要:
A hollow fiber filter device for dialysis having a housing and an end cap is described. The end cap is attached to an axial end of the housing, and has a curved channel in fluid communication with a fluid port, a fluid chamber having a flow path defined by a plurality of curved members connected to an upper interior surface. The distance between circumferentially adjacent curved members may decrease in a radially outward flow direction.
摘要:
The present invention relates to a hollow fiber made of a semipermeable membrane material, with the hollow fiber having exactly one restriction over its total length in which the inner diameter of the hollow fiber is reduced with respect to the section or sections of the hollow fiber adjoining the restriction. The present invention further relates to a hollow fiber bundle, to a filter and to a method for the manufacture of a hollow fiber or of a hollow fiber bundle.
摘要:
A filter device having two flow paths. The first flow path having at least one cap and fluid port. The second flow path surrounding the first fluid flow path and having at least one cap that overlaps the cap of the first fluid flow path. The second flow path also having at least one fluid port. The filter device providing a simple arrangement that is easily disinfected or sterilized.
摘要:
The invention relates to a capillary membrane which comprises at least two coextruded layers in a way corresponding to the solution of the invention. The invention also relates to a device for producing the coextruded multilayer capillary membrane.
摘要:
The invention relates to an apparatus for administering a medical fluid comprises a film-sheet pouch of a heat-sealed polymeric material, which includes a first chamber containing medical fluid and a second chamber for receiving used medical fluid, and comprises a cross-over conveying device detachably enclosed within a third chamber of the film-sheet pouch that includes a fluid conduit line, having a first end heat-sealed into the bonded seam defining the first chamber and a second end including a connector coupled to a peritoneal catheter. The apparatus of the present invention also includes at least one shut-off element to control the flow of fluid out of the first chamber into the conduit line.
