Temperature changing intracorporeal fluid delivery system

An intracorporeal fluid delivery device for heating a fluid to be administered to a patient, the device comprising:

• an outer shell, wherein the outer shell comprises an inner impermeable layer with an activation aperture, and an outer permeable layer, wherein the inner layer and the outer layer form an internal enclosure within the outer shell;
• a heat generation layer disposed inside the internal enclosure, wherein the heat generation layer comprises at least one first liquid permeable heater comprising a first exothermic reactant;
• an intracorporeal fluid conduit disposed within the outer shell or internal to the inner impermeable layer, wherein the intracorporeal fluid conduit has a path through the device, and wherein the intracorporeal fluid conduit further comprises an inlet port adjacent to a proximal end of the device and an outlet port adjacent to a distal end of the device;
• and
• a heater activation system disposed within the outer shell, comprising:
• at least one sealed bladder disposed inside the internal enclosure adjacent to the heat generation layer;
• and
• an activator liquid disposed in the at least one sealed bladder;
• wherein the activator liquid, when released from the at least one sealed bladder, contacts the heat generation layer and permeates the at least one first liquid permeable heater to combine with the first exothermic reactant causing a first exothermic reaction that heats fluid in the intracorporeal fluid conduit.
