- 穿刺針の基端部を支持する針ハブに対して保護カバーが相対回動可能で且つスライド移動可能とされており、該針ハブと該保護カバーとの相対回動によって該穿刺針の長さ方向を該保護カバーのスライド移動方向に合わせた状態で該保護カバーを該針ハブに対して相対的にスライド移動させることで該穿刺針の針先が該保護カバーで覆われるようになっていることを特徴とする針組立体。
- 前記穿刺針の長さ方向が前記保護カバーのスライド移動方向とは異なる方向で、前記針ハブと該保護カバーとの相対回動を位置決めする第一の回動防止機構を備えた請求項1に記載の針組立体。
- 前記穿刺針の長さ方向が前記保護カバーのスライド移動方向に合った方向で、前記前記針ハブと該保護カバーとの相対回動を位置決めする第二の回動防止機構を備えた請求項1又は2に記載の針組立体。
- 前記保護カバーが、手指で把持されるハウジングによって構成されている請求項1〜3の何れか1項に記載の針組立体。
- 前記保護カバーが、手指で把持されるハウジングに対して相対移動可能に組み付けられた別部材で構成されている請求項1〜3の何れか1項に記載の針組立体。
- 前記保護カバーを前記針ハブに対してスライド移動方向に付勢する付勢手段が設けられている請求項1〜5の何れか1項に記載の針組立体。
- 前記針ハブと前記保護カバーとの相対回動に伴い、前記穿刺針の長さ方向が該保護カバーのスライド移動方向と異なる相対回動位置では該保護カバーのスライド移動が阻止されて該穿刺針の針先が該保護カバーから突出した状態に維持されるようになっている一方、該穿刺針の長さ方向が前記保護カバーのスライド移動方向に合った相対回動位置では該保護カバーのスライド移動が許容される請求項1〜6の何れか1項に記載の針組立体。
- 前記針ハブには前記保護カバーとの相対回動の中心軸方向で両側に突出する回動軸が設けられていると共に、前記保護カバーにはスライド移動方向に延びて該針ハブの該回動軸が差し入れられる案内溝が設けられている一方、
該案内溝の一端部側には該案内溝の溝幅より大きい内寸の回動穴が設けられており、
前記針ハブの前記回動軸の外寸が周方向で異ならされて該案内溝の溝幅より小さい外寸と該案内溝の溝幅より大きい外寸とが周上の異なる位置に設定されていることによって、該回動軸の該回動穴内での回動位置に応じて、該回動軸の該案内溝への入り込みが阻止されて該回動穴に保持される係止位置と、該回動軸の該案内溝への入り込みが許容される係止解除位置とが、切り換えられる請求項7に記載の針組立体。 - 前記針ハブの前記保護カバーに対する回動端が規定されており、一方の回動端が該針ハブの該保護カバーに対するスライド移動が阻止された係止位置とされていると共に、他方の回動端が該針ハブの該保護カバーに対するスライド移動の阻止が解除された係止解除位置とされている請求項8に記載の針組立体。
- 前記針ハブを前記保護カバーに係止してスライド移動を阻止することにより前記穿刺針の針先が該保護カバーから突出した状態に保持すると共に、外部操作により該針ハブの該保護カバーへの係止を解除して該保護カバーのスライド移動を許容する操作部材が設けられた請求項1〜7の何れか1項に記載の針組立体。
- 前記保護カバーの先端には前記針ハブと該保護カバーとの回動方向に延びるスリットが形成されており、前記穿刺針が該スリットを通じて該保護カバーから露出されるようになっている請求項1〜10の何れか1項に記載の針組立体。
- 前記穿刺針を前記保護カバーで覆われる保護位置に保持する再露出防止手段が設けられている請求項1〜11の何れか1項に記載の針組立体。
