摘要： A system and method are provided, the system including a monitoring device to monitor sensory data of a patient and to provide a sensory data response thereto, and a control unit configurable to cool or warm circulated fluid through at least one contact pad for thermal exchange with the patient. The monitoring device can be configured to monitor a patient physiological response to a change in temperature of the patient (e.g. pursuant to induced hypothermia therapy), wherein a monitoring signal is provided by the monitoring device. A processor can be provided to process the monitoring signal and provide an output employable by medical personnel. The processor can be programmed to control automatically a temperature of the circulated fluid to cool or warm the patient in different treatment phases in accordance with a predetermined protocol, and process the sensory data signal to provide an output signal indicative of a sensory measurement.

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 can include an ultraviolet light-cured composition with a cross-linking copolymer, water, and glycerol. The hydrogel layer is provided to have a thermal conductivity of at least about 1.9 ca//hr-cm-° C.

摘要： A medical pad has multiple layers. A first 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 first layer. A second layer of the medical pad is interconnected to a second side of the first layer, opposite to the first side of the first layer. The second layer encloses a second thermal-exchange fluid that may have a freezing point of 0° C. or less. The medical pad is operable for thermal exchange between the second thermal-exchange fluid and the patient.
