    • A blood collection device combining an elongated needle cannula and vial insertion cannula fixed to a rotatable reel. The rotatable reel is supported in an L-shaped bowl and hollow stem combination. A sloping needle cannula is injected into a body or vein inside of a body so blood or other fluid flows from the body into the needle cannula and into the vial insertion cannula. A vial is inserted into the bowl until the vial insertion cannula penetrates the soft vial plug and the vial then is filled with blood or other fluid. When sufficient blood or fluid is drawn into the vial, the vial is removed and a lever or button is pushed, releasing a biased coil spring which causes the reel to rotate, thus winding the needle cannula and the vial insertion cannula around the reel, destroying the needle cannula and the vial insertion cannula and further pulling the needle cannula into the hollow stem and the vial insertion cannula into the bowl, preventing a person from being accidentally pricked or otherwise injured by either contaminated cannula.
    • 一种将细长的针插管和固定到可旋转卷轴上的小瓶插入套管组合的采血装置。 可旋转卷轴支撑在L形碗和中空杆组合中。 倾斜的针插管被注入到身体内部的身体或静脉内,使得血液或其它流体从身体流入针插管并进入小瓶插入套管。 将小瓶插入到碗中,直到小瓶插入套管穿透软瓶塞,然后小瓶中充满血液或其他液体。 当足够的血液或液体被吸入小瓶中时,取出小瓶并推动杠杆或按钮,释放引起卷轴旋转的偏置螺旋弹簧,从而将针套管和小瓶插入套管卷绕在卷轴上,破坏 针套管和小瓶插入套管,并且进一步将针套管拉入中空杆和小瓶插入套管进入碗中,防止人被任何被污染的插管意外刺伤或以其它方式受伤。

    • The invention comprises a needle aspiration safety syringe having a barrel, a plunger, a retractable needle, and a delayed engagement mechanism. The needle is functionally connected to the plunger by the delayed engagement mechanism such that when the plunger is retracted from an initial extended position, the needle does not retract immediately. The needle provides passage into the fluid receiving cavity, such that retraction of the plunger causes tissue fluid to flow from a target tissue through the needle and into the fluid receiving cavity. Further retraction of the plunger causes the delayed engagement mechanism to engage, whereupon the needle can be withdrawn completely into the fluid receiving cavity, such that the sharp end of the needle is no longer exposed. After the needle withdraws completely into the fluid receiving cavity, the needle cannot exit the fluid receiving cavity, such that the sharp end of the needle poses no danger of sticking a user or patient. Fluids can be stored in the fluid receiving cavity, and can be discharged through a port by depressing the plunger. When the plunger is depressed to discharge collected tissue fluid, the needle deforms inside the barrel.
    • 本发明包括具有镜筒,柱塞,可伸缩针和延迟接合机构的针抽吸安全注射器。 针通过延迟接合机构功能地连接到柱塞,使得当柱塞从初始伸出位置缩回时,针不会立即退回。 针提供通道进入流体接收腔,使得柱塞的缩回导致组织液从目标组织流过针并进入流体接收腔。 柱塞的进一步缩回导致延迟的接合机构接合,于是可以将针完全抽出到流体接收腔中,使得针的尖端不再暴露。 针完全退回到液体接收腔中后,针头不能离开流体接收腔,使得针尖的尖端不会粘附使用者或患者的危险。 流体可以存储在流体接收腔中,并且可以通过压下柱塞而通过端口排出。 当柱塞被压下以排出收集的组织液时,针在筒内变形。
