    摘要： An enhanced catheter introducer and method for making the same are disclosed. The catheter introducer may have a splittable sleeve assembly configured to be inserted into a blood vessel with a cannula. The cannula may then be removed, and a catheter may be inserted into the sleeve assembly. The sleeve assembly may be removed from the catheter by pulling handles of the sleeve assembly in different directions to split the sleeve assembly into two pieces. The sleeve assembly may have failure zones that enable the sleeve assembly to be easily split; the failure zones may take the form of thinned regions running along the length of the sleeve assembly. The sleeve assembly may be injection molded with a single step by injecting flows of molten plastic into a cavity of a mold such that the flows converge into an even distribution about the circumference of the sleeve. The mold may have a core pin designed to fit into the cavity. Through the use of the even distribution of flows, the core pin may seat within the cavity in an untensioned manner.

    摘要翻译： 公开了一种增强导管引导器及其制造方法。 导管导引器可以具有被配置成用插管插入血管的可分开的套筒组件。 然后可以移除套管，并且可以将导管插入套筒组件中。 可以通过沿着不同方向拉动套筒组件的手柄将套筒组件从导管中移除，以将套筒组件分成两部分。 套筒组件可以具有使得套筒组件容易分裂的失效区域; 故障区域可以采取沿套筒组件的长度延伸的变薄区域的形式。 套筒组件可以通过将熔融塑料流注入模具的空腔中，通过单个步骤注塑成型，使得流动汇集成围绕套筒圆周的均匀分布。 模具可以具有设计成适合于空腔的芯销。 通过使用均匀的流动分布，芯销可以以未张紧的方式安置在空腔内。

    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。
