To monitor irrigation fluid used during surgery.SOLUTION: A method includes ejecting irrigation fluid from a distal end of a probe so as to irrigate tissue, and receiving, over a period of time, initial signals indicative of respective temperatures of the distal end, from a temperature sensor in the distal end. The method also includes formulating from the initial signals a temperature range between upper and lower temperature thresholds and, when a further signal from the temperature sensor, received subsequently to the period of time, is indicative of a further temperature above the upper temperature threshold, raising an alarm that a bubble is present in the irrigation fluid.SELECTED DRAWING: Figure 1 【課題】 手術中に使用される灌注流体を監視すること。【解決手段】 プローブの遠位端から灌注流体を放出して組織を洗浄することと、ある期間にわたって、遠位端の温度センサから遠位端のそれぞれの温度を示す初期信号を受信することと、を含む、方法。方法はまた、初期信号から、上限温度閾値と下限温度閾値との間の温度範囲を定式化することと、ある期間の後に受信された温度センサからの更なる信号が上限温度閾値を超える更なる温度を示す場合、灌注流体中に気泡が存在するというアラームを発することと、を含む。【選択図】 図１
