Abstract
Systems for phase-change particulate slurry cooling equipment and methods to induce hypothermia in a patient through internal and external cooling are provided. Subcutaneous, intravascular, intraperitoneal, gastrointestinal, and lung methods of cooling are carried out using saline ice slurries or other phase-change slurries compatible with human tissue. Perfluorocarbon slurries or other slurry types compatible with human tissue are used for pulmonary cooling. And traditional external cooling methods are improved by utilizing phase-change slurry materials in cooling caps and torso blankets.
Claims38
A method of treating a patient comprising;
- administering to the patient a phase-change particulate slurry internally;
- and
- continuing to administer the slurry until a state of hypothermia is induced in the patient.
A method of treating a patient comprising:
- administering to the patient a phase-change particulate ice slurry internally;
- and
- continuing to administer the slurry until a state of hypothermia is induced in the patient.
A phase-change particulate ice slurry for inducing hypothermia in a patient comprising a medical grade saline solution and ice particles, the saline concentration being in a range between about 0.5% to 3.0%.
An apparatus for inducing hypothermia in a patient comprising:
- (a) a liquid vessel containing a phase-change particulate slurry;
- (b) means connected to the liquid vessel for delivering the phase-change particulate slurry internally to the patient;
- (c) means for continuously administering the phase-change particulate slurry from the liquid vessel to the patient until a state of hypothermia is induced in the patient.
An apparatus for inducing hypothermia in a patient comprising:
- (a) a liquid vessel containing a phase-change particulate slurry;
- (b) means connected to the liquid vessel for delivering the phase-change particulate slurry internally to the patient, whereby the phase-change particulate slurry is delivered from the liquid vessel to the patient until a state of hypothermia is induced in the patient.
An apparatus for administering a phase-change particulate slurry to a patient comprising:
- (a) a liquid vessel containing a phase-change particulate slurry;
- (b) a delivery device including a flexible, tubular member connected to the liquid vessel for delivering the phase-change particulate slurry internally to the patient, the flexible, tubular member having a first end and a second end, the first end insertable inside a patient, and the second end connected to the liquid vessel and in fluid communication with the liquid vessel, whereby the phase-change particulate slurry is delivered from the liquid vessel through the flexible, tubular member and into the patient until a state of hypothermia is induced in the patient.
