US Patent 8075524 - Syringe set with CNT heater

http://www.freepatentsonline.com/8075524.html

For many medical procedures injected fluid needs to be maintained near body temperature. This patent from Hon Hai Precision (Foxconn) teaches using carbon nanotube material as the heater in a syringe set. Claim 1 reads:

1. A syringe set comprising:

a syringe; and

a heating device comprising:

a heating module in thermal engagement with the syringe, the heating module comprising a heating element, a first electrode and a second electrode, wherein the heating element comprises a plurality of carbon nanotubes forming at least one electrically conductive path between the first electrode and the second electrode, and the first electrode and the second electrode electrically connect with the carbon nanotubes; and

a body supporting the heating module;

wherein the at least one electrically conductive path is adapted to convert a current into a heat and transfer the heat.
