摘要:
A thermal device includes an inflatable non-perforated blanket, a conduit structure, and a recirculating assembly. The inflatable non-perforated blanket is configured to transport warm air internally. The conduit structure is configured to provide conduit to transport the warm air externally to the inflatable non-perforated blanket. The recirculating assembly is configured to inflate the inflatable non-perforated blanket with the warm air and: (1) to cause the warm air to flow from the first port to the second port in a first direction, and (2) to recirculate the warm air through the conduit structure to flow from the second port to the first port in the first direction. The inflatable non-perforated blanket includes first and second sheets. The first sheet faces ambient air and has a first thermal conductivity. The second sheet faces the subject body and has a second thermal conductivity higher than the first thermal conductivity.
摘要:
Disclosed is a thermoregulation system, including an output port (54), an input port (62), a thermoregulation fluid supply system, an output pump (52) for pumping thermoregulation fluid out through the output port, an input pump (64) for pumping thermoregulation fluid in through the input port, and a pressure control system. The pressure control system is for selectively operating a pressurising element of a personal thermoregulation pack to apply a pressure independently of operation of the input (64) and output (52) pumps.
摘要:
An apparatus and method for providing heat exchange in the lungs of the mammal during partial liquid ventilation are provided. The apparatus and method can control delivery and removal of partial liquid ventilation to the lungs of a mammal by responding to pressure change in the lungs to minimize danger of causing barotrauma to the patient.

An extracorporeal blood cooling or heating circuit includes an intravenous catheter for withdrawing a patients blood coupled to a combined pump/heat exchanger device. One or more sensors are provided upstream and/or downstream of the pump/heat exchanger device for measuring pressure, temperature, fluid flow, blood oxygenation, and other parameters. A controller is operatively coupled to the pump/heat exchanger device and the one or more sensors to control the speed of the pump inside the pump/heat exchanger device and regulate the blood temperature by controlling the operation of the heat exchanger. The combined pump/heat exchanger device includes a housing having at least one inlet and at least one outlet, a pump portion defining a blood circuit inside the housing, and a heat exchanger portion contained within the housing for selectively heating or cooling the blood.
摘要:
Method for treatment of a body of a mammal in cardiac arrest, comprising the step of performing a therapeutic hypothermia of the body after the cardiac arrest has occurred, said therapeutic hypothermia comprising: cooling the body to a target temperature during a cooling time period, said cooling being performed by total liquid ventilation which comprises alternately filling lungs of the body with a cooling liquid and removing from the lungs said cooling liquid, maintaining the body at the target temperature for a hypothermia duration.
摘要:
Peritoneal heat exchange provides the benefit of extremely rapid cooling of the patient's target organs such as the heart and brain as well as facilitating global patient body temperature reduction to therapeutically effective temperatures. The heat exchange medium of the present invention is a chilled gaseous fluid suspension of frozen ice particles.
摘要:
Arrangements of components for use in support of a Hyperthermic Intraperitoneal Chemotherapy (HIPEC) System which conveys fluids from a system to a patient and back to the system in a complete circuit. The described arrangements provide multiple means of rapidly configuring the number of input lines and output lines into and out of the patient. Included are integral temperature probes in the inflow and outflow lines. Also included are various means of introducing and removing the fluids from the patient and additional temperature probes to be used at the discretion of the clinician.
摘要:
A prosthetic socket system includes a socket having an inner surface defining a socket cavity. A liner is adapted to receive a residual limb and be removably positioned within the socket cavity. A substantially sealed volume is defined between at least a portion of an outer surface of the liner and a corresponding portion of the inner surface of the socket. A wicking material is positionable in the substantially sealed volume and at least one cooling fluid can be carried by the wicking material. The at least one cooling fluid is adapted to selectively boil within the substantially sealed volume such that heat from the residual limb is converted into latent heat of vaporization by the at least one cooling fluid for a cooling effect.
摘要:
A method for providing and adjusting cerebral cooling in response to changes in a physiological parameter. A spray having a boiling point between 38-300° C. is delivered to the surface of a patient's nasal cavities. The spray causes cooling by direct heat transfer through the nasopharynx and hematogenous cooling through the carotids and the Circle of Willis. A physiological parameter, such as cerebral temperature, changes in cerebral blood flow or brain oxygenation is monitored. The delivery rate of the spray is adjusted in response to the physiological parameter.
摘要:
The present invention provides a method and device for non-invasive anatomical and systemic cooling. The method and device provide for cooling of various bodily fluid-containing spaces or surfaces, such as mucus-containing spaces or surfaces via delivery of a dry fluid not including a coolant into or upon the mucus-containing space or surface. Exposure of such mucus to the dry fluid results in evaporation and cooling of the anatomical feature and/or systemic cooling, as intended. In this fashion, therapeutic hypothermia may be achieved to provide for neuroprotection of various organs after ischemic insult, such the brain after cardiac arrest.
