Portable apparatus and method for the administration of heat exchange in the lungs of a mammal

An apparatus for the administration of heat exchange in the lungs of a mammal by cyclically delivering and removing a biocompatible liquid to and from the lungs, comprising:

• a) an ice water container having an open top end and adapted for containing ice water;
• b) a biocompatible liquid tank having an open top end with said biocompatible liquid tank disposed within the ice water container and adapted for containing a biocompatible liquid;
• c) a biocompatible liquid infusion reservoir having an open top end with said biocompatible liquid infusion reservoir disposed within the biocompatible liquid tank, said biocompatible infusion reservoir adapted to contain a predetermined volume of biocompatible liquid;
• d) a heat exchanger and ice water pump and sprayer disposed within the ice water container, with the ice water pump and sprayer having a tubular connection to the heat exchanger;
• e) a refill pump disposed within the biocompatible liquid tank, with the refill pump having a tubular connection with the infusion reservoir, whereby said refill pump can deliver biocompatible liquid from said biocompatible liquid tank to said infusion reservoir;
• f) a return pump and a return tube disposed within the biocompatible liquid tank, with the return pump and return tube having a tubular connection with the heat exchanger;
• g) a pump assembly platform, adapted for placement upon the open top end of the biocompatible liquid tank, said platform containing an infusion pump adapted for tubular connection to the infusion reservoir, an ice water jacket pump adapted for tubular connection to an ice water supply assembly disposed within the ice water container, and a suction pump adapted for tubular connection to the biocompatible liquid tank;
• h) an insulation jacket assembly having a watertight open passage within the jacket assembly;
• and
• i) a tube assembly comprising a biocompatible liquid infusion tube, a biocompatible liquid suction tube, an ice water supply tube, and an ice water return tube, said infusion tube partially disposed within the passage within the jacket assembly with an open end of tube extending through a first end of the jacket assembly and adapted for a tubular connection to the infusion pump and with the other open end of the tube extending through a second end of the jacket assembly and adapted for tubular connection to an endotracheal tube, said suction tube adapted at an open end for tubular connection to the suction pump and at the other open end to the endotracheal tube, said ice water supply tube partially disposed within the passage within the jacket assembly with an open end of the tube extending through the first end of the jacket assembly and adapted for tubular connection to the ice water pump and with the other open end disposed within the passage within the jacket assembly, and said ice water return tube adapted at an open end for tubular connection to the passage within the jacket assembly and positioned at the other open end for returning ice water to the ice water container;
• and said tube assembly further comprising a manually compressible air bag adapted for tubular connection to an oxygen supply source and to the endotracheal tube, whereby said ice water supply and return tubes can be utilized to circulate ice water from the ice water container within the insulation jacket assembly in order to cool the biocompatible liquid within said biocompatible liquid infusion tube that is disposed within the jacket assembly,
• whereby said apparatus can use ice water to cool the predetermined volume of biocompatible liquid and can cyclically deliver and remove the cooled predetermined volume of biocompatible liquid to and from the lungs of the mammal, while allowing the use of the manually compressible air bag to supply oxygen breaths to the lungs during the delivery of the biocompatible liquid to the lungs, with said apparatus capable of cooling the mammal at a rate of approximately 4.0° C. within approximately 5 minutes.
