Description

注射针头安全自毁组件
技术领域：
    本发明涉及一种注射针头安全自毁组件，属于医疗技术领域。
背景技术：
    专利公告号CN200620116145.9中提出专利名称为“安全静脉注射针结构”,它具有安全装置，仅单一动作即可将针头收纳于针筒中，可降低过多操作流程所造成的针扎机率，故可减少人为操作的安全隐患，但是使用中还是有被二次利用的可能性。
传统的注射针仅仅是采用护套的方式进行保护，但是其还是有被二次利用的可能性，因此会造成疾病和传播。
传统的注射针不能在有效使用和得到保护之间取得平衡，要不就结构繁杂，容易脱落，使用不易。
传统的注射针使用起来不方便，需要专门用胶带进行粘贴，对护士要求较高。
发明内容：
针对上述问题，本发明要解决的技术问题是提供一种注射针头安全自毁组件。
本发明的安全自毁组件，它包含输液导管、注射针针头、插针管，输液导管与插针座连接的插针管连接，所述的插针管的外侧滑动设置有保护套，保护套内部设置有簧片，插针管上设置有环形卡槽，且环形卡槽的下面设置有圆锥形凸台，所述的簧片自毁时卡合在环形卡槽内。
作为优选，所述的簧片有两个且在保护套内部对称分布，簧片与保护套是一体注塑成型的，簧片外侧是镂空体。
作为优选，所述的环形卡槽槽底与槽壁成直角，槽内上下壁相互平行；环形卡槽外圆直径大于簧片之间的距离。
作为优选：所述插针座与保护套之间为可脱开结构。
本发明的有益效果：能够在有效使用和安全自毁之间获得平衡，方便安全，使用迅速，不会交叉感染，有利于医疗卫生。
附图说明：
为了易于说明，本发明由下述的具体实施及附图作以详细描述。

图3为本发明的侧面剖面结构示意图；

具体实施方式：
如图1-7所示，本具体实施方式采用以下技术方案：它包含输液导管1、注射针针头6、插针管7，输液导管1通过插针管7与注射针针头6连接，其特征在于：所述的插针管7的外侧滑动设置有保护套3，保护套3内部设置有簧片，插针管7上设置有环形卡槽11，且环形卡槽11的下面设置有圆锥形凸台12，所述的簧片自毁时卡合在环形卡槽11内。
其中，所述的输液导管1连接插针座2，所述的插针座2上包含两个凸起状的锁扣8，锁扣8能够套入锁孔9，锁孔9位于保护套3上，锁扣8套入锁孔9将其锁定，所述的保护套3外部有把手4；所述的簧片有两个且在保护套3内部对称分布；即在节省成本和完成有效自锁的基础上，对称分布能有效实现自锁；所述的把手4包含两个且围绕保护套中心线对称分布；本处也是为了在人体上固定的时候的受力稳定和固定稳固；所述的把手4为扁平状；本处的扁平状为优选结构，但是其不对本具体实施造成限制；所述的插针座2包含手捏部分，所述的手捏部分上有花纹，所述的手捏部分朝内捏能将锁扣8和套入的锁孔9分离；所述的注射针针头6外部还套有针管护套5，针管护套5安装在保护套底座10上，所述的针管护套5为圆筒状的结构。
本具体实施方式中两块簧片之间的距离与插针管上的环形卡槽槽底圆直径相当， 当插针管顺着保护套内壁向下滑动时，锥形台会推开簧片滑动，直到簧片卡在环形卡槽内为止，同时保护套端口也封住了针头。
本具体实施方式能够将锁扣8和锁扣9脱离锁定状态，保护套3能够朝上滑行，朝上滑行的过程中，簧块会嵌合进环形卡槽11从而将保护套3覆盖住注射针针头6，并且由于其锁定并没有解锁结构，因此完成安全自毁。
以上显示和描述了本发明的基本原理和主要特征和本发明的优点。本行业的技术人员应该了解，本发明不受上述实施例的限制，上述实施例和说明书中描述的只是说明本发明的原理，在不脱离本发明精神和范围的前提下，本发明还会有各种变化和改进，这些变化和改进都落入要求保护的本发明范围内。本发明要求保护范围由所附的权利要求书及其等效物界定。
