Description

一种可换针头的安全注射器
技术领域：
本实用新型涉及一种一次性注射器，更具体地涉及一种适用国际标准型号针头的，并能使针头回缩损毁的医用安全注射器。
背景技术：
目前使用较多的一次性注射器，因接触病体后，被污染的针头暴露在外，医务人员或清扫员工稍不注意，极易被针头刺伤感染，根据目前公开的该技术方案，其缺点是：因结构不合理，在运输过程中或使用不当，都会造成自动损坏，另外针头固定后不能更换，其使用的型号也不符合国际标准，因此难以推广使用。
发明内容：
本实用新型提供一种可换针头的安全注射器，为克服了上述缺点，从结构设计上保证了该注射器能安全可靠地多次使用，使用完毕后又能方便可靠地将针头回缩，达到彻底损毁注射器之目的。本实用新型的技术方案是：一种可换针头的安全注射器，包括：针头、针栓、针筒；其特征是：针筒下端的内侧上设一微凸体，针筒的顶端置一筒颈，针头连接座置于筒颈内，筒颈的上口设有与针头连接座的外顶端相抵的内凸圈，针头连接座的内顶端置一针头座，其上置一针头，筒颈内侧上设一微凹槽，微凹槽内置一密封圈，针栓的顶端设一活塞，其外侧设有两条活塞凹槽，活塞凹槽内各置一密封圈套，活塞的顶端设一弹性活塞圈，其底部中间置有的倒梯形凹空与活塞中间置有的倒梯形凸块相扣，活塞的中央设一倒钩体。本实用新型可换用各种国际标准与非标准的针头，并能多次或一次使用，最终达到损毁之目的。
附图说明：
图1为本实用新型的结构示意图。
图2为本实用新型的损毁状态示意图。
其中：1针头  2针栓  3针筒  4微凸体  5筒颈6针头连接座  7内凸圈  8针头座  9微凹槽  10密封圈  11活塞12活塞凹槽  13密封圈套  14弹性活塞圈  15凹空  16凸块17倒钩体  18斜臂
具体实施方式：
如图1所示：本实用新型包括：针头1、针栓2、针筒3；针筒3下端的内侧上设一微凸体4，针筒3的顶端置一筒颈5，针头连接座6置于筒颈5内，筒颈5的上口设有与针头连接座6的外顶端相抵的内凸圈7，针头连接座6的内顶端置一针头座8，其上置一针头1，筒颈5内侧上设一微凹槽9，微凹槽9内置一密封圈10，针栓2的顶端设一活塞11，其外侧设有两条活塞凹槽12，活塞凹槽12内各置一密封圈套13，活塞11的顶端设一弹性活塞圈14，其底部中间置有的倒梯形凹空15与活塞11中间置有的倒梯形凸块16相扣，活塞11的中央设一倒钩体17。
如图1、图2所示：本实用新型的倒钩体17的斜臂18长度大于针头连接座6的内径，倒钩体17斜臂18的下端与弹性活塞圈14的表面处于一个平面，或稍低于该表面。
如图1、图2所示：本实用新型工作时，只要将针栓2用力向前推进，针筒3内的药液从针头1排出，当针栓2顶端的弹性活塞圈14抵达针筒3的筒颈5时，针筒3内的药液排尽，此时当针栓2拉出，即可反复多次使用，当用力将针栓2顶端的弹性活塞圈14推至筒颈5，使弹性活塞圈14被压缩后，活塞10中间的倒钩体17进入针头连接座6内，只要将针栓2向后拉动，倒钩体17的斜臂18两端斜挎在针头连接座6的内壁上，带动针头连接座6、针头座8，使其针头1收入针筒3内，而且针尖倒向针筒3内的一侧，此时再将针栓2向前推进，将针头1折弯，从而达到了损毁针头1，报废注射器之目的。
