摘要： A retracting needle assembly for use with a syringe barrel having a distally-facing annular sealing surface includes an outer hub having a conduit therethrough, a proximally facing annular sealing surface and means for connecting the outer hub to the syringe barrel. An inner hub having a passageway therethrough is provided. The inner hub includes a distally extending stem and a proximal flange for releasably engaging the outer hub. A needle having a sharp distal end and a proximal end is mounted in the passageway of the inner hub so that the sharp distal end projects distally outwardly. An elongate spring is disposed about the stem of the inner hub and is deflected to provide a bias between the inner hub and the outer hub. A hollow sleeve sized to fit within the conduit of the outer hub over the spring is provided. The sleeve has a sharp edge at its distal end for cutting through the flange to activate the retracting needle feature.

摘要： A single use syringe assembly includes a barrel having a chamber for retaining fluid, an open proximal end and a distal end including an elongate tip extending distally therefrom having a passageway therethrough in fluid communication with the chamber. A needle cannula having a lumen therethrough is connected to the elongate tip so that the lumen is in fluid communication with the passageway. An elongate needle shield having a longitudinal opening therein is hingedly connected to the barrel. A needle shield is capable of pivoting from an open position or a closed needle protecting position. The plunger including an elongate body portion and a stopper is slidably positioned in fluid-tight engagement with the inside surface of the barrel. Structure is provided for locking the plunger in the barrel by applying distally directed force to the plunger after fluid has been delivered from the chamber.
摘要翻译：一次性注射器组件包括具有用于保持流体的腔室的筒，敞开的近端和远端，其包括从其向远侧延伸的细长末端，其具有与腔室流体连通的通道。具有穿过其中的内腔的针插管连接到细长尖端，使得内腔与通道流体连通。在其中具有纵向开口的细长针护罩铰接地连接到筒体上。针护罩能够从打开位置或闭合的针保护位置枢转。包括细长主体部分和塞子的柱塞可滑动地定位成与筒体的内表面流体密封接合。提供了结构，用于通过在从腔室输送流体之后向柱塞施加向远侧的力而将柱塞锁定在筒体中。

摘要： A new tip for a conventional lancer that provides for improved blood flow from a lancet puncture site not located on a patient's finger. The new lancer tip includes a plurality of crenellations that exert rotational force on the skin surrounding the lancet puncture site when the lancer is rotated to enhance blood flow from the lancet puncture site.
