Description
ここで、挿入装置位置決め誘導システム100のブロック図である図1が参照される。システム100は、少なくとも1つの関心のある部位103b(例えば、患者の胴等の治療部位)をカバーする電磁場103bを発生させるように構成された電磁場発生器102、
関心のある部位103b(通常、被験者の胴)の解剖学的マップ(図3A~図3B)上の(挿入装置の遠位先端部分に位置する)先端センサの位置を示すために、センサ104、106、及び108等の複数の電磁センサを含む。システム100は、該電磁場発生器を操作し、薄板形センサ、基準センサ、及び登録センサから得られる信号を読み取り、該電磁場発生器に対するその位置及び向きを計算し、被験者の胴を表す解剖学的マップを生成するように構成されたプロセッサ110をさらに含む。プロセッサ110は、被験者の移動とは関係なく、並びに電磁場発生器102の位置及び/向きの偏差とは関係なく、事前に指定された解剖学的位置に関して先端センサの位置及び経路の解剖学的マップでの視覚化を容易にするように構成される。システム100は、プロセッサ110に動作可能なように接続され、解剖学的マップ上に、挿入部位の位置及び/又は挿入位置先端から挿入部位までの経路を表示するように構成されたモニタ112をさらに含む。いくつかの実施形態では、モニタ112は、オールインワンコンピュータの場合において等、プロセッサ110と統合されてよい。したがって、医療処置(例えば、肺とは対照的に胃に対する栄養チューブの挿入)の成功の判断が可能である。
胃腸管(例えば、経鼻栄養チューブ)、気管内チューブ、気管カニューレ、胃管、カテーテル管、又は輪状甲状靭帯切開管等の栄養チューブを含む。挿入装置の他の例は技術で周知である。
