PROBLEM TO BE SOLVED: To provide an ultrasonic irradiation apparatus in which safety can be secured even when operated by a patient for oneself, the ultrasonic wave is irradiated in a region other than lesion, and a systemic effect other than the region can be obtained.SOLUTION: An ultrasonic irradiation part 110 is an ultrasonic irradiation part for an arm region, fixed to the region in a position matched with direction where the longitudinal direction of the ultrasonic irradiation part 110 expands from an elbow region to a peripheral region, for irradiating ultrasonic waves from the region ranging from the elbow region to the peripheral region, or the region other than the lesion of a living body is a region ranging from an ankle to the peripheral region, and the ultrasonic irradiation part 110 is an ultrasonic irradiation part for a foot region, fixed to the region in the position matched with the direction where the longitudinal direction of the ultrasonic irradiation part 110 expands from a heel to a toe, for irradiating the ultrasonic wave to the region from the ankle to the peripheral region.COPYRIGHT: (C)2014,JPO&INPIT【課題】患者が自ら操作しても安全性を確保でき、超音波を病変部以外の局部に照射し、局部以外の全身性効果が得られる超音波照射装置を提供すること。【解決手段】超音波照射部110は、超音波照射部110の長手方向が肘部から末梢部に向かう方向に一致した位置関係で局部に固定されて肘部から末梢部までの一部に対して超音波を照射する腕部照射用超音波照射部であるか、又は、生体の病変部以外の局部は、足首から末梢部までの一部であり、超音波照射部110は、超音波照射部110の長手方向が踵から足指先に向かう方向に一致した位置関係で局部に固定されて足首から末梢部までの一部に対して超音波を照射する足部照射用超音波照射部である。【選択図】図3
