Description

一种防残液药液注射器
技术领域
本发明涉及医用用品，具体涉及一种防残液药液注射器。
背景技术
现有的注射器存在这样的技术问题，当注射剂完成注射后注射器内部存在大量的药物残留，面对较昂贵的药物的时候，如抗癌药，会造成药物的浪费。因此需要提供一种技术方案来解决这样的技术问题。
发明内容
本发明提供了一种防残液药液注射器，设计的目的是：减少昂贵药物的浪费。
本发明采用了如下技术方案：一种防残液药液注射器，包括注射器本体1、针座2、注射针3，所述注射针3与所述针座2连接，其特征在于，所述防残液药液注射器还包括第一注射活塞4、第二注射活塞5，所述第二注射活塞5的中心设有孔腔，所述第一注射活塞4通过所述孔腔与所述第二注射活塞5活动连接，所述第一注射活塞4的一端与所述注射器本体1的头部内腔6间隙配合
本发明的有益效果如下：本装置在使用过程中所述第一注射活塞4、第二注射活塞5的一端平齐，然后推动第二注射活塞5将注射器内腔中的药物推出进行注射。当推送至极限位置的时候。随时头部内腔6中含有残留的药液，此时推送第一注射活塞4，使得第一注射活塞4一端将头部内腔6中的药液挤出。减少昂贵药物的浪费。
附图说明
图1是本发明所述一种防残液药液注射器的结构示意图。 具体实施方式
以下结合附图与具体实施例对本发明作进一步描述。
图1中：注射器本体1、针座2、注射针3、第一注射活塞4、第二注射活塞5、头部内腔6。
一种防残液药液注射器，包括注射器本体1、针座2、注射针3，所述注射针3与所述针座2连接，其特征在于，所述防残液药液注射器还包括第一注射活塞4、第二注射活塞5，所述第二注射活塞5的中心设有孔腔，所述第一注射活塞4通过所述孔腔与所述第二注射活塞5活动连接，所述第一注射活塞4的一端与所述注射器本体1的头部内腔6间隙配合。
