PROBLEM TO BE SOLVED: To provide a spacer for mounting a probe for ultrasonic diagnosis which can be mounted the probe for the ultrasonic diagnosis of high frequency not less than 10 MHz without using a mounting member and can be commonly used even though the shapes of the probes are different in some degree and the probe for the ultrasonic diagnosis mounting the same.SOLUTION: The spacer 1 for mounting used being mounted on the probe for the ultrasonic diagnosis and being interposed between a body surface and the probe comprising a gel elastic body having adhesiveness has a probe distal end covering part 1a covering the distal end of the probe and adhering fixing parts 1b, 1b arranged continuously at both the side of the covering part 1a and adhered and fixed to the outer surface of the probe. A mounting member becomes dispensable, the wall thickness of the spacer can be made thin, thereby it makes possible to mount the probe for the ultrasonic diagnosis at the high frequency and to diagnose living body tissues close to the body surface.COPYRIGHT: (C)2012,JPO&INPIT【課題】10MHz以上の高周波数の超音波診断用探触子にも取付け部材を使用しないで装着でき、探触子の形状が多少異なっていても共用できる超音波診断用探触子の装着用スペーサーと、これを装着した超音波診断用探触子を提供する。【解決手段】超音波診断用探触子に装着され、体表との間に介在されて使用される装着用スペーサー1であって、該スペーサーは粘着性を有するゲル弾性体からなり、探触子の先端を被覆する探触子先端被覆部1aと、その両側に連設され且つ探触子の外面に粘着固定される粘着固定部1b,1bとを備えた装着用スペーサーとする。取付け部材が不要となり、スペーサーを薄肉化できるので、高周波数の超音波診断用探触子にも装着して体表近くの生体組織を診断を行うことが可能となる。【選択図】図1
