Claims

[Claims for Utility Model Registration] 1. A cylindrical housing with both ends open, a bundle of a plurality of substances or thin tubes for heat exchange provided inside the housing along its longitudinal direction, and the aforementioned housing. a pair of partition walls that liquid-tightly support each capillary tube so as not to block the inside of each capillary tube at both ends thereof; and a body fluid connected to each end of the housing and communicating with the inside of each capillary tube outside the partition wall. A body fluid substance or heat exchange device having a body fluid inlet port and a body fluid outlet port forming an inflow chamber or a body fluid outflow chamber and having a body fluid inlet port or a body fluid outlet port communicating with each of the chambers, The minimum inner diameter of the body fluid inlet is smaller than the minimum inner diameter of the body fluid outlet, and the density of the tubules of the tubule bundle of the partition located in the body fluid inflow direction is smaller than the density of tubules in other parts. A substance or heat exchange device for characterized body fluids. 2. The body fluid substance or heat exchange device according to claim 1, wherein the minimum inner diameter of the body fluid inlet is 3 mm or less. 3. The substance or heat exchange device for body fluids according to claim 1 or 2, wherein the part of the partition wall with a low density of tubules is the central part of the partition wall. 4. The body fluid substance or heat exchange device according to claim 3, which has a region in the center of the partition wall that has a diameter larger than the minimum inner diameter of the body fluid inlet and is free of thin tubes. 5. The body fluid inlet port and the body fluid outlet port have a substantially cylindrical passage formed along the solid axial direction of the body fluid inlet port or the body fluid outflow port, and the cylindrical passage of the body fluid inlet port. The length of the cylindrical passage in the body fluid outlet is divided by the distance from the opening end of the body fluid inlet to the bulkhead on the body fluid outflow chamber side.
