    • An apparatus to automatically secure an end of a needle after contact with a blood vessel. The apparatus includes a housing (102) and a biasing member (114), where the housing includes a hollow interior region extending between a proximal end and a distal end thereof. A proximal opening (106) is integrated into the proximal end, while a distal opening (110) is integrated into the distal end. The proximal and distal openings are configured to receive a needle (116) therethrough along a longitudinal axis. The biasing member is coupled to the housing and configured to apply a force to the needle. The force is oriented to displace the needle relative to the longitudinal axis upon retracting an end of the needle through the distal opening into the hollow interior region. Embodiments of the present invention may thus secure the end of the needle within the hollow interior region after use to prevent accidental needle sticks and exposure to blood and blood-borne pathogens.
    • 一种在与血管接触后自动固定针头的装置。 该装置包括壳体(102)和偏置构件(114),其中壳体包括在其近端和远端之间延伸的中空内部区域。 近端开口(106)集成到近端中,而远端开口(110)被集成到远端中。 近端和远端开口构造成沿着纵向轴线容纳穿过其中的针(116)。 偏压构件联接到壳体并且构造成向针施加力。 当将针的端部通过远端开口缩回到中空的内部区域中时,该力被定向成相对于纵向轴线移位针头。 因此,本发明的实施例可以在使用后将针的端部固定在中空内部区域内,以防止意外的针刺和暴露于血液和血源性病原体。
