Abstract: The present invention safety device is a one-piece needle assembly that has a base and a housing pivotally connected to the base. The base has a distal portion to which a needle is fitted. At the base there is formed longitudinally along its distal portion a catch mechanism that may be in the form of an anchor projection. At the back wall of the housing there is extended another catch mechanism that may be configured in the form of two clasping fingers. Also providing in the housing is an integral hook. As the housing and the base are pivoted relative to each other, and as the needle makes contact with the hook, the respective catch mechanisms at the base and the housing also make contact with each other, resulting in the coupling of the catch mechanisms and the coupling of the needle to the hook. As a result, the catch mechanisms are interlocked and the needle is fixedly retained by the hook within the housing. The catch mechanisms may also be configured as a hook and a latch in the form of a rib with an opening whereto the hook is fixedly coupled. The catch mechanisms may further be configured as respective interlockable pairs of loops and bosses. The gauge of the needle may be determined by the color of both the base and the housing, which are molded as a unitary single unit.

Abstract translation: 本发明的安全装置是一体式针组件，其具有基部和枢转地连接到基座的壳体。 底座具有一个远端部分，针头装配到该远端部分。 在基部处，沿着其远端部分纵向地形成可以是锚定突起的形式的捕捉机构。 在壳体的后壁处延伸另一个可以被配置成两个扣紧手指形式的止动机构。 在外壳中也提供了一个整体的钩子。 当壳体和基座相对于彼此枢转时，并且当针与钩接触时，基部和壳体处的相应的卡止机构也彼此接触，导致卡扣机构和 针与钩的耦合。 结果，锁定机构是互锁的，并且针被壳体内的钩固定地保持。 捕获机构还可以被配置为具有开口的肋形式的钩和闩锁，钩子固定地联接在该开口上。 捕获机构还可以被配置为各自可互锁的环和凸起对。 针的尺寸可以由基座和外壳的颜色确定，这两种颜色被模制成一体的单一单元。
