Abstract: Heat exchange pads for use on a patient are described herein. An example heat exchange pad can include a surface defining an internal volume and having a flexible patient contacting portion, an inlet fluidly connected to the internal volume for delivery of fluid into the internal volume, an outlet fluidly connected to the internal volume for removal of fluid from the internal volume, and at least one extended surface structure positioned within the internal volume to disrupt laminar flow of fluid from the inlet to the outlet.

Abstract: Disclosed herein are dual temperature, dual reservoir devices for providing contrast therapy. An example device has separate liquid heating and cooling systems, each of which have their own designated liquid reservoir. In some embodiments, each system is served by its own dedicated energy source, and has its own water flow circuit that is equipped with pressure relief valves and check valves. Some exemplary systems also include electronically controlled three way valves that ensure that either heated liquid or cooled liquid is flowing to and from the therapy pad at any given time, but never simultaneously. This allows for nearly instantaneous switching between the cooling and heating functions. Certain embodiments of the contrast therapy devices disclosed herein also have programmable features that enable a user to adjust certain variables of the therapy, or allow for a personalized therapy regimen to be developed.

Abstract: Example heat exchange pads are described herein. A heat exchange pad can include an input compartment, an output compartment arranged in fluid connection with the input compartment, and an internal member disposed between the input and output compartments. The internal member can include an array of holes formed therein. Additionally, the internal member can be configured to produce impinging flow convection heat transfer in proximity to a heat exchange surface of the output compartment.
