器。[Scope of Claim for Utility Model Registration] (1) A large number of heat exchange tubes each having an internal space that is fluid-tightly partitioned from the blood circulation space in a cylindrical blood circulation space along the longitudinal axis of the blood circulation space. A section is arranged along the direction of the heat exchange tube and performs heat exchange between the blood flowing through the blood circulation space through the tube wall of the heat exchange tube and the heat exchange medium flowing through the internal space of the heat exchange tube. In the medical heat exchanger, a blood introduction tube that introduces blood into the blood circulation space and a blood outlet tube that draws blood out of the blood circulation space are perpendicular to the longitudinal direction of the blood circulation space and A medical heat exchanger characterized in that each of the medical heat exchangers is extended from the outside along a straight line touching the circumferential surface and communicated with a blood circulation space. (2) A large number of heat exchange tubes are arranged spaced apart from each other along the longitudinal direction of the housing in a cylindrical housing with both ends closed, and a plurality of heat exchange tubes are provided at both ends of the housing. The partition walls hold the heat exchange tubes liquid-tightly on the housing side wall without blocking the openings of the heat exchange tubes, and partition the inside of the housing into three spaces, both partition walls and the housing side wall. A blood introduction tube and blood extending from the outside along a straight line perpendicular to the longitudinal direction of the housing and in contact with the circumferential surface of the housing are inserted into the blood circulation space formed in the center of the housing by the outer wall of the heat exchange tube and the outer wall of the housing. The heat exchange medium flows into one of the two heat exchange medium circulation spaces formed at the end portion of the housing, which are fluid-tightly partitioned from the blood circulation space and communicated with the internal space of the heat exchange tube body. A medical heat exchanger according to claim 1, wherein one tube is connected to the other and a heat exchange medium outflow tube is connected to the other tube. (3) According to the scope of claim 2 of the utility model registration, the blood inlet tube communicates with the blood circulation space from the vicinity of one partition wall, and the blood outlet tube communicates with the blood circulation space from the vicinity of the other partition wall. Medical heat exchanger as described. (4) Any of claims 1 to 3 of the utility model registration claim, characterized in that the blood inlet tube and the blood outlet tube are rotated approximately 180 degrees on the circumferential surface of the blood circulation space. A medical heat exchanger described in .
