PROBLEM TO BE SOLVED: To provide a catheter detection device which eliminates a detection coil located in a dead zone and can reliably detect a location of a catheter end.SOLUTION: A catheter detection device comprises: a detected part located at an end of a catheter and a detection part detecting a location of the detected part. The detected part is composed of a transmission coil generating electromagnetic waves. The detection part has: 4 first detection coils 23B, 23D, 23F, 23H which are located at symmetrical positions with respect to intersections on a coordinate axis on orthogonal coordinate axes respectively and whose respective coil axes coincide with the direction heading for the intersections and 4 second detection coils 23A, 23C, 23E, 23G which are located at symmetrical positions with respect to intersections of the coordinate axes on the coordinate axes and whose respective coil axes coincide with directions orthogonal to directions heading for the intersections.COPYRIGHT: (C)2016,JPO&INPIT【課題】不感帯に位置する検出コイルを無くし、カテーテル先端の位置を確実に検出できるカテーテル検出装置を提供する。【解決手段】カテーテルの先端に配置した被検出部と、被検出部の位置を検出する検出部とを備えたカテーテル検出装置である。被検出部は電磁波を発生する送信コイルからなり、検出部は、直交する座標軸上で座標軸の交点に対する対称な位置にそれぞれ配置され、それぞれのコイル軸が交点に向かう方向に一致する4個の第1検出コイル23B,23D,23F,23Hと、座標軸上で座標軸の交点に対する対称な位置にそれぞれ配置され、それぞれのコイル軸が交点に向かう方向と直交する方向に一致する4個の第2検出コイル23A,23C,23E,23Gとを有する。【選択図】図6
