- 先鋭な穿刺体を先端部に有するランセットとばね部材とがハウジング内に収容されており、該ランセットが該ばね部材で付勢されることによって、該穿刺体の先端が該ハウジングの開口部から突出して穿刺作動すると共に、該穿刺作動後に該穿刺体の先端が該ハウジング内に入り込んだ引込み位置に後退するようにされたディスポーザブル型採血器具において、
前記ハウジングの前記開口部の周辺部分が、内部を視認可能な透明性を有する可視部とされていると共に、
前記ばね部材が、前記ランセットが前記引込み位置に後退したときに、前記穿刺体の先端の位置よりも該穿刺体の後退方向側に位置している
ことを特徴とするディスポーザブル型採血器具。 - 前記ランセットが、前記ばね部材により前記穿刺体の突出方向に付勢された状態で、該穿刺体の先端を前記ハウジング内に収容させた待機位置に配されているときに、該ランセットを該ばね部材の付勢力に抗して該待機位置に保持する係止手段が、該ランセットと該ハウジングとの間に設けられていると共に、
該係止手段による該待機位置への該ランセットの保持を該ハウジング外部からの操作で解除する係止解除手段が設けられている請求項1に記載のディスポーザブル型採血器具。 - 前記ランセットにおいて、自由端とされた先端部分が該ランセットの外周面に接近する方向に撓み変形可能とされた可撓アームが突設されていると共に、該ランセットが前記待機位置に配されているときに該可撓アームが係止される係止部が前記ハウジングに設けられており、それら可撓アームと係止部とを含んで前記係止手段が構成されている一方、
外部からの操作によって該可撓アームの先端部分が該ランセットの外周面へ向けて撓み変形することにより、該可撓アームの該係止部への係止を解除する前記係止解除手段が構成されている請求項2に記載のディスポーザブル型採血器具。 - 前記可撓アームが、前記ランセットに沿って前記穿刺体の突出方向の前方側から後方側に向かって延びるように突設されており、該可撓アームの延出方向の中間部分において前記係止部に係止されている一方、
前記係止解除手段において外部からの操作が行われる操作部が、該可撓アームの該係止部への係止部分よりも延出方向の先端側に設けられている請求項3に記載のディスポーザブル型採血器具。 - 前記穿刺体の先端を覆うカバー部が前記ランセットの先端部に対して分離可能に設けられていると共に、
該ランセットが、前記ばね部材により該穿刺体の突出方向に付勢された状態で、該穿刺体の先端を前記ハウジング内に収容させた待機位置に配されているときに、該ハウジングに対する係合作用に基づいて該ランセットを該ばね部材の付勢力に抗して該待機位置に保持する係合部が、該カバー部に設けられている請求項1〜4の何れか1項に記載のディスポーザブル型採血器具。
