Abstract
一次性使用无菌过滤型静脉推注注射器，是由针管、针柄、毛细管、上壳、过滤膜、针座、注射器串联胶结组成，它是在原上壳与注射器之间，固定封装一个，可用来过滤药液中的不溶性微粒、杂质的过滤器，本实用新型的优点在于：这种集针管、针柄、毛细管、上壳、过滤膜、针座、注射器为一体的一次性使用无菌过滤型静脉推注注射器，大大地方便了医务工作者，在临床治疗抢救患者过程中的使用程序，减少了使用时，药液过滤器、注注射器未配套使用，无法过滤药液中的不溶性微粒、杂质，易造成血液***污染这一环节，就是减少了给患者造成不必要伤害的机会，确保了临床治疗抢救患者过程中的医疗质量，保证患者的身体健康和生命安全。
Description
技术领域
本实用新型涉及一种一次性使用无菌注射器领域，具体是涉及一次性使用无菌过滤型静脉推注注射器。
背景技术
在临床治疗抢救患者的过程中，静脉推注药液，是抢救的重要的必需的手段之一，在静脉推注药液时，需要用静脉输液针和注射器组合合用。现在临时使用的是把一次性使用静脉输液针(无过滤器)和注射器相配合使用，是由针管、针座和注射器组成，这种进行静脉推注药液的缺点是：由于没有过滤装置，在静脉推注药液的过程中，推注溶液中的死亡细菌、玻璃碎屑、粉剂中一些不溶性微粒、杂质，随注射液进入人体的血液中，特别是这些不溶性微粒、杂质，会与血液产生血栓子，会对人体中的一些小血管、神经末梢等血液供应***产生堵塞现象，造成这些细胞的死亡，导致一些器官的功能性损坏的现象，给患者造成不必要的严重的隐性伤害。
发明内容
本实用新型要解决的技术问题是，提供一种既能有效地过滤不溶性微粒、杂质，同时又不需要另外安装过滤器的注射器进行静脉推注药液。
为了解决上述问题，是通过以下技术方案实现的。一种一次性使用无菌过滤型静脉推注注射器，是由针管、针柄、毛细管、上壳、过滤膜、针座、注射器组成，其特点是：过滤膜安装在上壳和针座之间，针管、针柄、毛细管、上壳、过滤膜、针座、依次串联胶结在一起，针座与注射器连接。
本实用新型是一种一次性使用无菌过滤型静脉推注注射器，与现有一次性静脉输液针、药液过滤器分体技术相比，简化使用程序，注射器和药液过滤器的组合使用，可将药液中的不溶性微粒、杂质过滤出去，杜绝一切对人体有损害的杂质通过注射液进入人体血液***内，造成对人体的伤害。保护人们的身体健康和生命安全。从而使用十分方便、安全。
附图说明
图1为一次性使用无菌过滤型静脉推注注射器整体结构示意图
图中
针管1、针柄2、毛细管3、上壳4、过滤膜5、针座6、注射器7
具体实施方式
下面结合附图1与具体实施例对本实用新型作进一步详细描述。
如图1所示一次性使用无菌过滤型注射针，是由针管1、针柄2、毛细管3、上壳4、过滤膜5、针座6、注射器7串联胶结组成。过滤膜5固定封装在上壳4和针座6之间。根据临床治疗抢救患者的需要，选择合适型号的一次性使用无菌过滤型静脉推注注射器，就可以进行静脉注射了。
