PROBLEM TO BE SOLVED: To provide a highly-operable injection-needle recapping device capable of reliably preventing an injection-needle erroneous pricking accident.SOLUTION: The injection-needle recapping device includes a cylindrical body part 12Aa on an upper end, where the body part 12Aa and a lower-end bottom part 12Ab are connected via two connecting parts 15A. The height of the connecting parts 15A is so set that a tip of a second cap 6 attached to a first cap 5 does not exceed the bottom part 12Ab, and an interval between the body part 12Aa and the bottom part 12Ab is formed into a wide space other than the two connecting part 15A.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】注射針の誤刺事故を確実に防ぐことができ、操作性の良い注射針リキャップ器を提供する。【解決手段】上端に円柱形の本体部12Aaが形成され、本体部12Aaと下端の基底部12Abとは、連結部15A2つを介して連結している。第一キャップ5に付けた第二キャップ6の先端は,基底部12Abを越えないように連結部15Aの高さが設定され、本体部12Aaと基底部12Abとの間は、2つの連結部15A以外は広い空間となっている。【選択図】図2
