Abstract

本实用新型公开了一种防回血的输液器,包括输液管道,所述输液管道上设有滴速观测管,所述输液管道上设有滴速调节装置,所述滴速观测管内放置塑料小球,所述输液管道上设有输液针。本实用新型结构简单、观测方便,能有效防止回血。

Description

防回血的输液器
技术领域
本实用新型涉及一种防回血的输液器。
背景技术
主要用于静脉输液的经过无菌处理的、建立静脉与药液之间通道的常见的输液器式样一次性的医疗耗材。一般由静脉针、护帽、输液软管、药液过滤器、流速调节器、滴壶、瓶塞穿刺器、进气管空气过滤器连接组成。
实用新型内容
    本实用新型提供一种结构简单、观测方便,能有效防止回血的输液器。
本实用新型解决技术问题提供如下方案:
一种防回血的输液器,包括输液管道,所述输液管道上设有滴速观测管,所述输液管道上设有滴速调节装置,其特征在于:所述滴速观测管内放置塑料小球。
所述输液管道上设有输液针。
本实用新型输液器在观测管内放置塑料小球,由于小球的密度小于水的密度,小球会悬浮与液面上,不会阻碍液体的流通,当液体输完后,小球会随着液体下降,堵住粗管与细管的链接口,达到了防回血作用。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
参见附图,一种防回血的输液器,包括输液管道1,所述输液管道1上设有滴速观测管2,所述输液管道1上设有滴速调节装置3,所述滴速观测管2内放置塑料小球4,所述输液管道1上设有输液针5。

Claims (2)

1.一种防回血的输液器,包括输液管道,所述输液管道上设有滴速观测管,所述输液管道上设有滴速调节装置,其特征在于:所述滴速观测管内放置塑料小球。
2.根据权利要求1所述防回血的输液器,其特征在于:所述输液管道上设有输液针。
