摘要： A spike adapter and blunt cannula spike adapter assembly comprises a spike adapter having a hollow chamber extending axially therethrough from a first body end to a second body end. The hollow chamber is adapted to receive and accommodate attachment with a blunt cannula therein. A spike shaft projects axially outwardly away from the adapter body second end and has a sharpened tip at a distal end. A spike cover is disposed over the spike shaft to cover the sharpened tip. The spike shaft includes a hollow channel extending axially therethrough that is adapted to accommodate placement of a blunt cannula shaft concentrically therein to allow the blunt cannula to access medicine containers having unslit septums or stoppers. The spike adapter body includes axially extending grooves that accommodate blunt cannula tongues therein to form a tongue and groove attachment therebetween. Notches project from surface portions of the adapter body disposed across the grooves, and are designed to engage blunt cannula tongues to lock the blunt cannula into the spike adapter. The adapter body includes surface portions that are diametrically opposed to the grooves and that are deformable in a radially inwardly direction to permit the elastic deformation of the adapter body to unlock the tongues from the respective notches.
摘要翻译： 尖钉适配器和钝头插管尖钉适配器组件包括具有从第一主体端到第二主体端轴向延伸穿过的中空室的钉式适配器。 中空腔适于接纳并容纳与其中的钝头套管的附件。 尖钉轴从适配器主体的第二端轴向向外突出，并且在远端具有尖锐的尖端。 尖钉盖设置在钉轴上方以覆盖尖锐的尖端。 尖钉轴包括轴向延伸穿过其中的中空通道，其适于容纳钝性插管轴同心地放置在其中，以允许钝头插管进入具有不起泡的隔膜或塞子的药物容器。 钉适配器主体包括轴向延伸的凹槽，其在其中容纳钝的插管舌片，以在它们之间形成榫舌和凹槽附接。 槽口从设置在槽周围的适配器主体的表面部分突出，并被设计成接合钝的插管舌片以将钝头插管锁定到钉式适配器中。 适配器主体包括与凹槽径向相对的表面部分，并且可沿径向向内的方向变形，以允许适配器主体的弹性变形使舌片从相应的凹口解锁。
