Abstract:
1. A molecular exchange device comprising: a casing, extending from a proximal end portion to a distal end portion, supporting at least two fluid conduits extending from the proximal end portion to the distal end portion; the at least two fluid conduits comprising a first fluid conduit and a second fluid conduit, the first fluid conduit comprising a lumen allowing fluid flow in a first direction from the proximal end portion to the distal end portion of the casing, the second fluid conduit comprising a lumen allowing fluid flow in a second direction, opposite the first direction, from the distal end portion to the proximal end portion of the casing; the casing comprising at least first and second exchange apertures located between the distal end portion and the proximal end portion, wherein the first fluid conduit comprises a porous portion exposed by the first exchange aperture, and the second fluid conduit comprises a porous portion exposed by the second exchange aperture; wherein the proximal end portion of the casing is configured to house a proximal end portion of the first fluid conduit and a proximal end portion of the second fluid conduit, and the distal end portion of the casing is configured to house a distal end portion of the first fluid conduit and a distal end portion of the second fluid conduit such that the proximal end portions of the first and second fluid conduits are supported by the casing proximal end portion and the distal end portions of the first and second fluid conduits are supported by the casing distal end portion; and a separator extending from the proximal end portion of the casing to the distal end portion of the casing, the first and second fluid conduits being arranged on opposite sides of the separator; wherein the first fluid conduit is spaced from the separator within the first exchange aperture to define a gap between the first fluid conduit and the separator, the gap allowing the porous portion of the first fluid conduit to be exposed to an external fluid around the entire circumference of the porous portion of the first fluid conduit; wherein the second fluid conduit is spaced from the separator within the second exchange aperture to define a gap between the second fluid conduit and the separator, the gap allowing the porous portion of the second fluid conduit to be exposed to an external fluid around the entire circumference of the porous portion of the second fluid conduit.
