The invention relates to a forced air warming blanket for regulating a temperature of a patient, the blanket having a patient drape detachably connected thereto.

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.

Methods for treating fluid overload in a subject comprise shifting fluids directly and non-invasively from an interstitial compartment of the subject to skin of the subject through controlled local sweating. Methods of the invention allow for removal of excess fluid from the interstitial compartment of the subject and treat fluid overload in the subject. Sweat stimulation systems comprise a chamber and first and second relative humidity sensors. The chamber is sized to fit around a body part of a subject, comprises an inlet and an outlet, and is configured such that air flows through the chamber from the inlet to the outlet. The first relative humidity sensor is operably located inside the inlet, and the second relative humidity sensor is operably located proximate the outlet.

An apparatus for facilitating delivery of conditioned air across a barrier in a cage for holding an animal patient to a blanket arrangement providing the conditioned air to the patient. The apparatus comprising a first duct part, a second duct part and a mounting mechanism arranged to mount the first duct part on one side of the barrier and the second duct part on the other side of the barrier opposite thereto, to provide a duct for ducting conditioned air across the barrier. The barrier comprising bars or mesh, and the apparatus further comprising a seal arrangement to provide at least a partial seal across the bars or mesh. The mounting mechanism comprises a fastening mechanism for fastening the first and second duct parts to each other across the barrier, wherein the fastening mechanism is a keyhole-style fastening arrangement utilising a plurality of headed projections on a flange of the first duct part engagable with respective keyhole-style apertures on a flange of the second duct part.

Various implementations include a Human Thermoregulation Simulator (HTRS) that simulates the natural and primary thermoregulatory functions of a patient that are relevant during therapeutic hypothermia procedures. For example, in various implementations, a HTRS includes a core container configured to be at least partially filled with water, and the core container includes a heat generator configured to heat the water inside the core container. A middle container is disposed concentrically around the core container, and the middle container includes a foam layer configured to be saturated by water. An outer container is disposed concentrically around the middle container, and the outer container includes a network of tubing disposed on at least a portion of an inner surface of the outer container. The HTRS also includes a pump configured to circulate water from the core container through the network of tubing.

Aspects of the present disclose related to a system. The system includes a warming device having at least a first zone and a second zone and a sensor. The system also includes a controller that includes one or more processor circuits configured to receive a first sensor reading from the sensor corresponding to a first zone, wherein the first sensor reading corresponds to a first heat transfer rate. The one or more processor circuits are configured to determine whether the sensor reading is sufficient and increase a first heat transfer rate to a second heat transfer rate in the first zone in response to the sensor reading being insufficient.

Aspects of the present disclosure relate to a convective blanket that includes an air permeable upper sheet having a periphery. The convective blanket includes a lower sheet bonded to the upper sheet with a peripheral seal proximate to the periphery of the upper sheet to form an interior space therein between the upper and lower sheets. The convective blanket includes a wing portion partially surrounded by a portion of the peripheral seal and a body portion. Additional aspects relate to a system including the convective blanket and a method that uses the convective blanket.

A thermal pack (10) for therapeutic treatment of a mammal that includes a bladder (12, 4) and a separator element insert (22). The bladder (12, 14) is formed of a pair of superposed sheets (12, 14) of flexible, heat conductive liquid impermeable polyurethane material and includes an inlet (18) and an outlet (20). The sheets (12, 14) are welded together at a central spine (17) and along a series of branches (16) so as to provide a turning, tortuous fluid passageway therein. The separator element insert (22) is received within the fluid passageway and provides a fluid conveying track that extends throughout the fluid passageway from the inlet (18) to the outlet (19) to maintain the sheets (12, 14) in spaced apart relationship to mitigate restrictions in fluid flow when the pack (10) is flexed out of the plane of the sheets (12, 14). The separator element insert (22) includes a series of deflector ribs (36, 38, 40, 42, 44) along the fluid conveying track that deflect fluid flow away from the separator element insert (22) and into the fluid passage way along at each turn of the fluid passageway.

Embodiments include a heated underbody support with electrosurgical grounding, such as a heated mattress, heated mattress overlay, or heated pad for supporting a person. The heated underbody support may include a flexible heating element formed of a sheet of conductive or semi-conductive material, a first bus bar along a first edge of the heating element adapted to receive a supply of electrical power, a second bus bar extending along the second edge of the heating element, and a temperature sensor. The heated underbody support may include a layer of compressible material adapted to conform to the person under pressure from the person resting upon the support located beneath the heating element. A water resistant shell may encase the heating element, the first and second bus bars, and the temperature sensor. A return electrode wire may be electrically connected to the flexible heating element to connect to an electrosurgical generator.

A self-heating warming blanket includes a pliable outer shell forming a liquid impermeable enclosure. A heat generation layer disposed inside the enclosure has a plurality of liquid permeable heater compartments containing an exothermic reactant. The blanket also has a heater activation system including a sealed bladder containing an activator liquid inside the enclosure. An activation strip extends from outside the outer shell into the enclosure. One segment of the strip is an unsealing segment connected to the bladder. Another segment of the strip is a handle segment outside the outer shell. Pulling on the handle segment opens the bladder and releases the activator liquid into the enclosure where at least a portion of it permeates at least one heater compartment and combines with the exothermic reactant contained therein to initiate an exothermic chemical reaction that heats the warming blanket.
