PROBLEM TO BE SOLVED: To provide a medical ultrasonic transducer that can singly or simultaneously perform diagnosis and treatment and that is equipped with a cooling means capable of easily suppressing generation of heat from the ultrasonic transducer.SOLUTION: The medical ultrasonic transducer includes an ultrasonic transducer 11 for diagnosis, an ultrasonic transducer 12 for treatment, and a cooling pad 16. The ultrasonic transducer 11 for the diagnosis and the ultrasonic transducer 12 for the treatment, which are disposed in close vicinity to each other, can singly or simultaneously perform the diagnosis and the treatment. In the cooling pad 16, a second container 16b made of a resin film thinner than a resin film constituting a first container and filled with water is housed in the first container 16a made of the resin film and filled with a coolant causing an endothermic reaction by the presence of the water. The coolant in the first container causes the endothermic reaction by making the second container broken by an external impact.COPYRIGHT: (C)2012,JPO&INPIT【課題】 診断と治療が単独で又は同時に行え、超音波振動子の発熱の抑制を容易に行える冷却手段を備えた医療用超音波振動子を提供する。【解決手段】 医療用超音波振動子は、診断用超音波振動子11及び治療用超音波振動子12と、冷却パッド16とから構成される。近接配置された診断用超音波振動子11及び治療用超音波振動子12は診断と治療が単独で又は同時に行える。前記冷却パッド16は、水の存在で吸熱反応を起す冷却剤を充填した樹脂フィルム製の第1の容器16aの内部に、前記第1の容器を構成する樹脂フィルムよりも更に薄い樹脂フィルム製の水を充填した第2の容器16bが収容され、外部からの衝撃により前記第2の容器が破れて前記第1の容器内部の冷却剤が吸熱反応を起すように構成されている。【選択図】 図1
