Abstract
【解決手段】 血液採集器具は、フラッシュバックチャンバと、フラッシュバックチャンバを被覆する排気栓とを有した針ハブを具える。排気栓は、排気栓を通る気体の流れは許容し、排気栓を通る液体の流れを防止する。静脈カニューレにはハブに取り付けられ、フラッシュバックチャンバへと延びる。非患者側のカニューレは、ハブに取り付けられ、また、フラッシュバックチャンバに連通して延びる。受動的な遮蔽器具は、ハブが取り付けられ、静脈カニューレが露出される近位位置から、静脈カニューレが部分的に遮蔽される遠位位置まで移動できる。フラッシュバックチャンバは、静脈へのアクセスを早く表示することができる。その結果、流体採集チューブは、非患者側のカニューレに連通する場所に配置され、同時に安全シールドの移動のトリガとなる。
