Embodiment Construction

[0537] In the drawings, a semi-permeable arrangement according to the invention is shown. Figure 1 to Figure 3 A first embodiment of a semi-permeable arrangement and its components are shown, generally indicated by reference numeral 1 . The semi-permeable arrangement has a structural frame 2 and a plurality of porous members 3 arranged within the structural frame 2 . The structural frame 2 is a single layer frame formed by a plurality of structural bars 4 . The structural bars 4 are arranged in a first set of structural bars 5 and a second set of structural bars 6, wherein each set of structural bars 5, 6 has a plurality of structural bars arranged in spaced apart parallel relationship. The interval between the structural rods 4 of the first group of structural rods 5 and the second group of structural rods 6 is 3 mm. The first set of structural rods 5 is arranged perpendicular to the second set of structural rods 6, and they are woven together to form a mesh network 8 with...

Abstract

A semipermeable arrangement for use in clinical, agricultural, industrial and / or environmental settings. The semipermeable arrangement has a structural arrangement formed from a material such as ePTFEthat has an affinity to a lubricating fluid such as perfluorocarbon. The structural arrangement may be infused with a lubricating fluid such that the semipermeable arrangement resists fouling. The semipermeable arrangement is further arranged with barriers to prevent or limit the movement of the lubricating fluid through at least part of the structural arrangement. The semipermeable arrangement further has passageways that are free from the presence of, and / or cannot be infused with, lubricating fluid. The passageways permit the movement of fluids such as air, water and dissolved substances through the structural arrangement. The semipermeable arrangement is thereby both self-cleaning and porous and has a wide range of uses.

Description

technical field [0001] The present invention relates to semi-permeable arrangements for use in clinical, agricultural, industrial and / or environmental settings. Background technique [0002] A semi-permeable arrangement such as a porous membrane limits the material passing through its passages to only certain selected substances. Typically, the selected substances include water and dissolved substances, and prevent solid particles and microorganisms from passing through the porous membrane. However, the excluded particles and microorganisms can settle on the inlet side of the porous membrane, and the microorganisms can colonize the surface and plug the pores of the membrane ("fouling"). When enough material builds up and / or microbes spread across the membrane surface, the membrane will no longer be effective. Where porous membranes are used clinically, for example where they are applied or implanted on a recipient, the porous membrane may become a source of microbial infec...
