Description

一种静脉输液器
技术领域
本发明属于医疗器械技术领域，具体涉及一种静脉输液器。
背景技术
静脉输液器是一种常见的医疗耗材，经过无菌处理，建立静脉与药液之间通道，用于静脉输液。一般由静脉针或注射针、针头护帽、输液软管、药液过滤器、流速调节器、滴壶、瓶塞穿刺器、空气过滤器等八个部分连接组成，部分静脉输液器还有注射件，加药口等。而现有的静脉输液器存在易使空气进入人体血液和静脉针易从输液管上脱落等缺点。
发明内容
本发明的目的是解决现有静脉输液器存在易使空气进入人体血液和静脉针易从输液管上脱落的技术问题，提供一种静脉输液器。
为解决上述技术问题，本发明采用的技术方案为：
一种静脉输液器，包括瓶塞穿刺器、上输液管、墨菲氏滴管、下输液管、药液过滤器、流速调节器和静脉针，所述瓶塞穿刺器的尾部与上输液管的进液口连接，上输液管的出液口与墨菲氏滴管的进液口连接，墨菲氏滴管的出液口与下输液管的进液口连接，下输液管的出液口与静脉针头皮针管的连接头连接，流速调节器设在下输液管上，其中：药液过滤器设在上输液管上。
在下输液管的出液口设有连结帽，在连结帽的内壁设有螺旋状凸缘，静脉针头皮针管的连接头与下输液管的连结帽套接，螺旋状凸缘用于防止静脉针头皮针管的连接头从下输液管的连结帽中脱落或空气进入。
所述静脉输液器还包括设在墨菲氏滴管内腔中的浮球。
所述静脉输液器还包括加热套，加热套包裹在上输液管或下输液管的外壁。
所述静脉输液器还包括设在下输液管上的夹持装置。
在所述药液过滤器上设有加药口。
本发明采用以上技术方案，于背景技术相比，具有以下优点：
1)药液过滤器设在上输液管上，药液过滤器上设有加药口，便于加药，减少了药液过滤器残存的气体进入人体血液；
2)静脉针头皮针管的连接头与下输液管的连结帽套接，增大了静脉针头皮针管的连接头与下输液管连接处的摩擦力，使得静脉针不易从输液管上脱落或空气进入；
3)在滴壶内腔中的浮球，在药液滴完后，浮球堵住下输液管的进液口，截断流通；
4)在上输液管或下输液管的外壁包裹加热套，患者在冬天输液时，避免了冰冷的药液进入人体血液给患者带来不适；下输液管上的夹持装置用于输液室将输液器固定于输液瓶架上或患者近身处，防止其晃动带来安全隐患。
附图说明
图1是本发明的结构示意图；
图2是本发明静脉针头皮针管与下输液管连接处分离的结构示意图。
具体实施方式
如图1和图2所示，本实施例中的一种静脉输液器，包括瓶塞穿刺器1、上输液管9、墨菲氏滴管2、下输液管10、药液过滤器4、流速调节器5和静脉针7，所述瓶塞穿刺器1的尾部与上输液管9的进液口连接，上输液管9的出液口与墨菲氏滴管2的进液口连接，墨菲氏滴管2的出液口与下输液管10的进液口连接，下输液管10的出液口与静脉针7头皮针管的连接头连接，流速调节器5设在下输液管10上，其中：药液过滤器4设在上输液管9上。
在下输液管10的出液口设有连结帽11，在连结帽11的内壁设有螺旋状凸缘11，静脉针7头皮针管的连接头与下输液管10的连结帽11套接，螺旋状凸缘11用于防止静脉针7头皮针管的连接头从下输液管10的连结帽11中脱落或空气进入。
所述静脉输液器还包括设在墨菲氏滴管2内腔中的浮球3。
所述静脉输液器还包括加热套6，加热套6包裹在上输液管9或下输液管10的外壁。
所述静脉输液器还包括设在下输液管10上的夹子13。
在所述药液过滤器4上设有加药口12。
上述实施例中的夹子13还可以用其它夹持装置代替。
