Abstract
A portable apparatus and method for providing a cooled liquid for vascular administration are disclosed. The portable apparatus includes a source of liquid for vascular administration, a cooling reservoir for receiving liquid from the source, and a sorption-based heat exchanger for cooling liquid in the cooling reservoir by a sorption-based process. The heat exchanger may include an evaporative area for receiving and vaporizing a refrigerant, a sorptive material for sorping vaporized refrigerant, and a heat exchange member for conducting thermal energy from liquid in the cooling reservoir into the evaporative area. Additional componentry may be provided for fluidly interconnecting and controlling the flow of liquid from the source to the cooling reservoir and from the cooling reservoir to a vascular interface device. Such componentry may be conveniently packaged in a sterilized manner together with at least the cooling reservoir.
