Abstract
【解決手段】 上記針装置12は、針カニューレ20と、針カニューレ20に取り付けられたハブと、前記針カニューレ20に沿って摺動可能なチップガード26とを備えている。上記チップガード26は、上記針カニューレ20の先端部が安全に被覆された先端位置に摺動可能である。折り畳み可能なガード装置28は、上記ハブに取り付けられ、ハブから上記チップガード26に延びる折り畳み可能な一対の板ばね86を備えている。折り畳まれた各板ばね86に対するグリップを解放するといった単純な操作により、上記板ばね86を折り畳み前の状態へ弾性復帰させることができ、これにより上記チップガード26を針カニューレ20の先端周りに被覆係合するように変位させることができる。
