PROBLEM TO BE SOLVED: To substantially prevent catheter insertion failure and provide a low profile infusion set.SOLUTION: An infusion set comprises a base, and an inserter removably connected to the base. A catheter is movable from a first catheter position, in which the catheter is disposed substantially entirely within the inserter, to a second catheter position, in which a free end of the catheter is disposed outside the base. An introducer needle is located within the catheter and movable with the catheter between a first introducer needle position, in which the introducer needle is disposed substantially entirely within the inserter, and a second introducer needle position, in which a free end of the introducer needle is disposed outside the base. A spring member moves the catheter from the first catheter position to the second catheter position, and moves the introducer needle from the first introducer needle position to the second introducer needle position to facilitate insertion of the catheter. The spring member is disposed substantially entirely within the base when the catheter is in the second catheter position.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】カテーテル挿入の失敗を実質上防止し、低プロファイルの注入セットを提供する。【解決手段】注入セットが、ベースと、ベースに着脱可能に接続された挿入器とを含む。カテーテルは、挿入器内に実質上完全に配置された第１のカテーテル位置から、カテーテルの自由端部がベースの外部に配置される第２のカテーテル位置へ動くことができる。導入針は、カテーテル内に位置し、挿入器内に実質上完全に配置された第１の導入針位置と、導入針の自由端部がベースの外部に配置される第２の導入針位置との間を、カテーテルとともに動くことができる。ばね部材は、カテーテルを第１のカテーテル位置から第２のカテーテル位置へ動かし、導入針を第１の導入針位置から第２の導入針位置へ動かして、カテーテルの挿入を容易にする。カテーテルが第２のカテーテル位置にあるとき、ばね部材はベース内に実質上完全に配置される。【選択図】図２
