Re: AW: AW: [HSF] the little heat exchanger for arch op´s

[prasannasimha]

I have seen these sort of coils in disposable things but was wondering 
if they have a reusable one- that would be great -
Some years ago (I think around 14 years back) I made a heating cooling 
blanket using 1/4th inch tubes coiled in a counter current mechanism to 
warm and cool our patients. Actually one of my perfusionists presented 
it in their conference.
Hence my interest especially wrt to design.
