    摘要： A needle assembly especially suited for hypodermic syringe use in which an axially collapsible sleeve is positioned over the needle. The sleeve includes an upper axially rigid portion sized to mount over the base portion of the needle, an axially collapsible intermediate portion, and an axially rigid lower portion defining a central bore sized to telescopically receive and protect the lower pointed end of the needle. In use, the sleeve selectively collapses axially as the needle enters the subject so that the point of the needle is never exposed during insertion, and selectively extends axially during withdrawal of the needle so that again the pointed tip of the needle is never exposed.

    摘要翻译： 特别适用于皮下注射器使用的针组件，其中轴向可折叠套管位于针上方。 套筒包括上部轴向刚性部分，其尺寸适于安装在针的基部上，可轴向折叠的中间部分和限定中心孔的轴向刚性下部，该中心孔的尺寸适于可伸缩地接收和保护针的下尖端。 在使用中，当针进入受试者时，套筒选择性地塌陷，使得针头在插入过程中不会露出，并且在抽出针时可选择性地延伸，从而针头的尖端从未暴露。

    摘要： Safety needle assemblies that include a needle having a sharp distal tip and a needle tip cover mounted on the needle are disclosed. The needle tip cover includes a proximal wall having an opening for the needle to pass therethrough. The needle tip cover urges against the needle in a ready to use position and shields the sharp distal tip in the secured position. The needle tip cover is moved proximally by a spring after the needle has been inserted into a patient a predetermined depth.

    摘要： A medical needle shield apparatus is provided that includes a needle hub having a needle cannula extending therefrom. At least one shield is extensible from a retracted position to an extended position to enclose a distal end of the needle. The shield includes a binding member disposed within the shield and defines binding surfaces that form an aperture configured for slidable receipt of the inner needle. The binding member includes at least one drag inducing member that engages the inner needle during slidable receipt to create a drag force. The drag force facilitates rotation of the binding member such that the binding surfaces engage the inner needle to prevent slidable movement. The shield and/or hub includes a retention element engageable between the shield and hub and a sheath retention element. The hub includes a magnifier for viewing fluid flashback.

    摘要： A safety needle assembly of an infusion set for infusing fluids into a subcutaneously implanted access port is disclosed. The needle assembly is configured to prevent fluid/vapor escape therefrom so as to reduce or prevent fluid exposure to a clinician using the needle assembly. In one embodiment, the needle assembly comprises a handle portion including a needle extending therefrom, the needle defining a lumen for passage of a fluid therethrough. The needle assembly also includes a safety assembly defining a needle hole through which the needle initially extends. The safety assembly is selectively and axially slidable along the needle in order to shield a distal tip of the needle and prevent user contact therewith. A fluid isolation component is included in the safety assembly for isolating fluid escape from the needle to prevent exposure to a clinician.
