Apparatus for vascular guide wire insertion with blood flashback containment features |
摘要 |
The device includes a barrel having a flashback chamber. An inner cannula in the flashback chamber communicates with an inserter needle mounted on the barrel. The inner cannula includes an aperture communicating with the flashback chamber. A porous vent plug is slidably disposed in the chamber in fluid-tight engagement with both the barrel and the inner cannula. The vent plug can be slid from a proximal position where the aperture in the inner cannula is exposed to a distal position where the aperture in the inner cannula is blocked. A guide wire in the inner cannula blocks blood flow. |
