Patent ID: 7827815

Claim:
A portable apparatus for selective, on-demand bodily cooling of a patient by providing a cooled liquid for administration into a vascular system of a patient, comprising: a portable source of a liquid for vascular administration; a portable cooling reservoir for receiving liquid from said source, including: an inlet that is one of interconnected and interconnectable to the portable source for receiving said liquid therefrom; an outlet that is one of interconnected and interconnectable to a vascular interface device; a portable sorption-based heat exchanger for cooling said liquid received in said portable cooling reservoir from said portable source, free from electrical power requirements, including: a vessel containing refrigerant; an evaporative area for receiving and vaporizing said refrigerant therein; a sorptive material for sorping vaporized refrigerant; and, a heat exchange member for conducting thermal energy from said liquid received in said portable cooling reservoir into said evaporative area; and, an actuator selectively actuable by a user to flow said refrigerant from said vessel into said evaporative area to provide selective cooling of said liquid received in said portable cooling reservoir for vascular administration to a patient.
