There is provided a method of manufacturing a heat exchanger including a hollow fiber membrane layer that is configured to include a plurality of hollow fiber membranes each of which has a hollow portion allowing a heat medium to pass therethrough and is obtained from a base material in which the plurality of hollow fiber membranes are accumulated so as to form an overall shape of a cylindrical body. The manufacturing method includes a winding step of winding each of the hollow fiber membranes about an axis of the cylindrical body while the hollow fiber membrane is caused to be wound along an axial direction of the cylindrical body so as to obtain the base material. In the winding step, each of the hollow fiber membranes is wound about the axis of the cylindrical body within a range from one round to less than two rounds during one round trip in which the hollow fiber membrane starts from one side toward the other side of the cylindrical body in the axial direction, turns back at the other side, and returns to the one side again.

An extracorporeal blood cooling or heating circuit includes an intravenous catheter for withdrawing a patient's blood coupled to a combined pump/heat exchanger device. One or more sensors are provided upstream and/or downstream of the pump/heat exchanger device for measuring pressure, temperature, fluid flow, blood oxygenation, and other parameters. A controller is operatively coupled to the pump/heat exchanger device and the one or more sensors to control the speed of the pump inside the pump/heat exchanger device and regulate the blood temperature by controlling the operation of the heat exchanger. The combined pump/heat exchanger device includes a housing having at least one inlet and at least one outlet, a pump portion defining a blood circuit inside the housing, and a heat exchanger portion contained within the housing for selectively heating or cooling the blood.
