Abstract Means for controlling the temperature of intravenous fluids being administered to a patient and comprising a pair of relatively thin films of flexible silicone rubber bonded together to form a generally rectangular parallelepiped having a pair of opposed major surfaces and having a plurality of generally parallelly disposed flow channels extending therebetween, the flow channels being arranged transversely to the elongated axis of said parallelepiped; means defining an inlet orifice along one edge thereof communicating with an inlet manifold at one end of said parallel flow channels and an outlet orifice along the opposite edge thereof communicating with an outlet manifold at the opposite end of said flow channels; and a highly thermally emissive coating applied along one of said major surfaces, and a highly thermally reflective coating applied to the opposed major surface.
The means as defined in claim 1 being particularly characterized in that said thermally emissive and thermally reflective coatings are applied externally of said generally rectangular parallelopiped.
Claim 2
Dependent Claim
22 words
The means as defined in claim 1 being particularly characterized in that said relatively thin flexible films are fabricated from silicone rubber.
Claim 3
Dependent Claim
30 words
The means as defined in claim 1 being particularly characterized in that means are provided along said flexible films for attaching the structure to the skin surface of a human.
Claim 4
Dependent Claim
38 words
The means as defined in claim 1 being particularly characterized in that pressure sensitive coatings are applied along the surface coated with thermally emissive material for securing said structure to the surface of the skin of a human.
Claim 5
Dependent Claim
37 words
The means as defined in claim 1 being particularly characterized in that said rectangular parallelopiped has an elongated axis and a shorter transverse axis, and said parallelly disposed flow channels are generally parallel to said transverse axis.
