摘要： Improved systems and methods for extracorporeal blood temperature control and patient temperature control, e.g., for induced hypothermia and optional normothermia, may include or otherwise employ a heat exchanger for cooling/warming of a fluid, a thermal exchange module having fluidly isolated first and second volumes, and a fluid pump for circulating the fluid through the heat exchanger and the first volume of the thermal exchange module. A blood pump may be provided for the flow of blood through the second volume of the thermal exchange module, and a first controller may be provided for providing output signals for use in operation of the heat exchanger to selectively control thermal exchange between the fluid circulated through the first volume of the thermal exchange module and the blood flowed through the second volume of the thermal exchange module, thereby providing for selective cooling/warming of the blood. A multi lumen catheter may be utilized for the flow of blood from a patient vascular system to the second volume of the thermal exchange module, and for flow of blood from the second volume of the thermal exchange module back to the patient vascular system. The circulated fluid may be optionally circulated through a patient contact pad(s) for contact cooling/warming, wherein patient cooling/warming may be provided in a first mode via blood cooling/warming in the thermal exchange module, and patient cooling/warming may be provided in a second mode via thermal exchange by the contact pad(s).

摘要： An improved medical pad for contact thermal exchange with a patient includes a fluid circulation layer for containing a thermal exchange fluid circulatable therethrough, a first port and a second port for circulating the thermal exchange fluid in to and out of the fluid circulation layer, and a hydrogel layer interconnected to and extending across one side of the fluid circulation layer to define an adhesive surface for adherence to a patient's skin. The hydrogel layer comprises an ultra violet light-cured composition that includes a cross-linking copolymer in an amount of between about 15% to 30% by weight of the composition, water in an amount of between about 15% to 40% by weight of the composition, and glycerol in an amount of between about 25% to 35% by weight of the composition. The hydrogel layer is provided to have a thermal conductivity of at least about 1.9 ca//hr-cm-° C.

摘要： A system for extracorporeal blood temperature control includes a heat exchanger configured to cool a circulated fluid, a thermal exchange module including a first volume fluidly isolated from a second volume, a fluid pump, a blood pump, and a controller. The fluid pump can pump the circulated fluid through the heat exchanger and the first volume of the thermal exchange module. The fluid pump can establish a negative pressure within the first volume of the thermal exchange module The blood pump can pump blood through a first blood flow line, the second volume of the thermal exchange module, and a second blood flow line. The controller can cool the blood by controlling thermal exchange between the circulated fluid pumped through the first volume of the thermal exchange module and the blood pumped through the second volume of the thermal exchange module.

摘要： A medical pad having a dual layer portion including a fluid circulation and containment layers and a single layer portion including the fluid circulation layer. The fluid circulation layer is for containing a first thermal-exchange fluid circulatable therethrough, with the medical pad being operable for thermal exchange between the first thermal-exchange fluid and a patient through a first side of the fluid circulation layer. A fluid containment layer of the medical pad is interconnected to a portion of second side of the fluid circulation layer, opposite to the first side of the fluid circulation layer. The fluid containment layer encloses a second thermal-exchange fluid that may have a freezing point of 0° C. or less. Portions of the fluid circulation layer that extend beyond the fluid containment layer define flaps that provide additional area for fluid circulation.
