1. A medical device comprising: a multilayer printed circuit board (PCB) comprising a heating element on an inner layer of the PCB; a single-cell electrical power source to power the heating element; and a chamber adapted to contain a liquid, at least part of the chamber being defined by a thermally conductive material configured to provide a thermal transfer interface between the chamber and the PCB, wherein the interface between the thermally conductive material and the PCB comprises a larger surface area than the area of the chamber defined by the thermally conductive material.
