Abstract
The present technology relates to systems and methods for managing core body temperature in a subject using, for example, an esophageal heat exchange device. In one aspect, the disclosure provides a method for reducing duration of a hospital stay in a subject undergoing core body temperature management.
Core Innovation
The invention relates to devices, systems, and methods for controlling core body temperature in a subject in need thereof. A heat exchange device comprises a heat exchange region having at least one lumen providing a fluid path for flow of a heat exchange medium, and a portion of the heat exchange region is orally placed in an esophagus with a proximal portion extending beyond an oral cavity.
A thermally insulating sleeve surrounds at least part of an outer surface of the proximal portion extending beyond the oral cavity. The thermally insulating sleeve comprises an elongate tubular structure positioned between the proximal portion and exposed skin of the subject to reduce or prevent direct contact between the outer surface of the proximal portion and exposed skin.
The method includes initiating flow of the heat exchange medium through the fluid path to control core body temperature prior to initiation of any anti-shivering interventions. The subject is assessed for a shivering response, and at least one anti-shivering intervention is provided if and only if the subject demonstrates mild to severe shivering.
Claims Coverage
The provided independent claims include two inventive features centered on an esophageal heat-exchange region with a thermally insulating sleeve, together with temperature control initiated prior to anti-shivering interventions and a conditional shivering-based anti-shivering strategy.
Esophageal heat-exchange region with thermally insulating sleeve
A heat exchange device has a heat exchange region with at least one lumen providing a fluid path for flow of a heat exchange medium; at least part of the heat exchange region is orally placed in an esophagus with a proximal portion extending beyond an oral cavity; and at least part of the outer surface of the proximal portion is surrounded with a thermally insulating sleeve comprising an elongate tubular structure.
Reducing or preventing direct skin contact via sleeve positioning
The thermally insulating sleeve is positioned between the proximal portion of the heat exchange region and exposed skin of the subject to reduce or prevent direct contact between the outer surface of the proximal portion and the exposed skin.
Initiating heat-exchange-medium flow for core temperature control
Flow of the heat exchange medium is initiated through the fluid path.
Initiating heat-exchange flow prior to anti-shivering interventions with conditional treatment
Heat exchange-medium flow is initiated to control core body temperature prior to initiation of any anti-shivering interventions, the subject is assessed for a shivering response, and at least one anti-shivering intervention is provided if and only if the subject demonstrates mild to severe shivering.
The claim coverage combines esophageal placement of a heat exchange region with a thermally insulating, elongate tubular sleeve positioned to reduce or prevent direct contact with exposed skin, and further requires initiation of heat-exchange-medium flow before anti-shivering interventions with treatment given only when mild to severe shivering is demonstrated.
Stated Advantages
Reducing duration of a hospital stay in a subject undergoing core body temperature management.
Reducing or preventing direct contact between the outer surface of the proximal portion of the heat exchange region and exposed skin of the subject.
Minimizing anti-shivering interventions by providing at least one anti-shivering intervention if and only if the subject demonstrates mild to severe shivering.
Documented Applications
