Abstract
【解決手段】波長が600nm〜1400nmの近赤外光が照射されることにより蛍光を発する発光剤が表面に塗布されるか又は練り込まれた発光可能な医療具1と、この医療具1に向かって上記近赤外光2を照射する光源3と、上記医療具1の発光剤が発する近赤外蛍光を受光するカメラ4と、このカメラ4が撮影した画像5を映し出すモニタ6とを具備してなる医療具位置確認システム。
【選択図】図1
Description
観察することによって行われている。
爆を受け続けるという問題がある。また、X線を透過する樹脂製の医療具には利用し難いという問題がある。
図1及び図2に示すように、この医療具位置確認システムでは、近赤外蛍光を発する医療具1と、この医療具1に向かって近赤外光2を照射する光源3と、上記医療具1の発光剤が発する蛍光を受光するカメラ4と、このカメラ4が撮影した医療具1の画像5を映し出すモニタ6とが用いられる。
図3に示すように、この実施の形態2で用いられる医療具1は、血管8内に挿入されるステントである。
具1であるステントの位置、姿勢等を容易に確認しつつ施術することができる。
図4に示すように、この実施の形態3で用いられる近赤外蛍光を発する医療具1は、血管8内に挿入される注射針である。
置関係を確認しつつ注射針を静脈内に簡易かつ正確に刺入することができる。
図5に示すように、この実施の形態4で用いられる近赤外蛍光を発する医療具1は、血管8内に挿入されるカテーテルである。
ルの先端や全体の位置、先端の進行方向等を確認しつつカテーテルを動脈内に簡易かつ正確に挿入することができる。
静脈にカテーテルを入れる際に、発光剤に適した波長と静脈が吸収しやすい波長の赤外光を一緒に照射しカメラで撮影することによって、静脈と医療具である注射針やカテーテルの位置確認を同時に行い、注射針やカテーテルが正確に静脈に入っているか否かを確認することができる。
