Abstract
A blanket includes a cavity therewithin defined between spaced layers of the blanket directing a fluid conduit therethrough. The fluid conduit is in cooperative and fluid communication with a control housing to include cooling and heating structure in association with a pump to direct cooled or heating fluid through the conduit within the blanket cavity. A modification of the invention includes a secondary reservoir to include fluid at ambient air temperature to stabilize a blanket temperature as an alternative to creating a temperature gradient relative to the ambient temperature environment of the blanket.
