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。
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: ::
发明内容： 针对上述问题， 本发明要解决的技术向题是提供一种注射针头安全
本发明的安全自毀组件， 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， 所述的簧片自毀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， II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。 本发明的有益效果： 能够在有效使用和安全1 毀之间获得平衡， 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 i为本发明使用前状态结构图；
圏 4为本发明自毁后结构 IE面示意国；
图 δ为本发明自毁后立体结构示意图；
图 6为本发明的连接底座部分结构局部放大图；
