    • The present invention is a safety syringe for use with a plurality of interchangeable needles. The plurality of needles may be inserted by the user into the safety syringe for use. In operations, the user selects the desired needle, e.g., a needle having a particular gauge or size or of a particular type. The user inserts the needle (14) into a safety syringe (10) comprising a barrel (6), a needle assembly area (18) located within or attached to the barrel and a plunger (66). The needle couples to the syringe by a number of means. For instance, a locking mechanism (20, 22) may be used by which a needle hub located within the needle assembly has an area adapted to mate with a corresponding area on the needle. Or, the needle may be formed as part of a separate needle assembly, whereby the user will place the entire needle assembly onto the end of the syringe barrel. During use, the user operates the syringe like other safety syringe, using one hand to depress the plunger, which ultimately causes a spring to propel the needle into the barrel of the syringe.
    • 本发明是一种用于多个可互换针的安全注射器。 多个针可以由使用者插入安全注射器中以供使用。 在操作中,用户选择所需的针,例如具有特定规格或尺寸或特定类型的针。 用户将针(14)插入安全注射器(10)中,安全注射器(10)包括筒体(6),位于筒内或附着于针筒的针组件区域(18)和柱塞(66)。 针通过多种方法将针连接到注射器。 例如,可以使用锁定机构(20,22),通过该锁定机构,位于针组件内的针毂具有适于与针上的相应区域配合的区域。 或者,针可以形成为单独的针组件的一部分,由此使用者将整个针组件放置在注射器筒的端部上。 在使用过程中,使用者像其他安全注射器一样操作注射器,用一只手按压柱塞,这最终导致弹簧推动针头进入注射器的枪管。

    • A metal roof truss assembly is provided comprising a plurality of elongated structural members, including a top chord, a bottom chord, and a web member. Each structural member comprises a planar base and planar legs extending from the longitudinal edges of the base. The base and the legs define an open longitudinal channel. A flange integral with the longitudinal edges of each leg has a planar first portion extending outwardly from the legs and a planar second portion extending from the longitudinal edges of the first portion of the flanges. The end of a first structural member is inserted into the channel defined by the legs and the base of a second structural member. The inserted end of the first structural member has no flanges for a length equal to at least the depth to which the first structural member is received in the channel of the second structural member so that the outer surface of the legs of the first structural member are adjacent the inner surface of the legs of the second structural member.
    • 提供一种金属屋顶桁架组件,其包括多个细长结构构件,包括顶弦,底弦和腹板构件。 每个结构构件包括平面基部和从基部的纵向边缘延伸的平面腿。 基部和腿部限定开放的纵向通道。 与每个腿部的纵向边缘成一体的凸缘具有从腿部向外延伸的平面的第一部分和从凸缘的第一部分的纵向边缘延伸的平坦的第二部分。 第一结构构件的端部插入由腿部和第二结构构件的基部限定的通道中。 第一结构构件的插入端没有法兰,其长度至少等于第一结构构件在第二结构构件的通道中被容纳的深度,使得第一结构构件的腿的外表面是 邻近第二结构构件的腿的内表面。
