<p>In one variation, a temperature-maintenance device includes a heater (1016) and is placeable in a circulation loop of an ultrasound transducer coupling bolus (1076), for degassing circulating liquid of the loop and for operating the heater for performing temperature control of the liquid. A temperature setpoint, such as a normal body temperature, for the liquid at the bolus may be entered. A device, either open- or closed-looped with respect to fluid flow, may include, in some variations, a degassing chamber, a water trap (1012), and an intervening cooler, all vacuumized by a vacuum pump (1024). The chamber may be configured and aligned for letting condensation automatically drain out. The water trap may be emptied, automatically and without the need for user intervention, by a motorized trap emptier and/or be emptiable by the user.</p> |
