Abstract

一种防反流输液器。主要解决现有输液器在输液结束时易出现血液反流的问题。其特征在于:针头(1)与输液管(2)之间有阀管(3),阀管(3)内下部有隔板(4),隔板(4)上有1个以上通液孔(5),阀管(3)内隔板(4)上有阀球(6)。该防反流输液器能够在输液结束时防止血液反流现象产生。

Description

防反流输液器
技术领域
本实用新型涉及一种内科所用的输液器,尤其是防反流输液器。
背景技术
在内科医治过程中,普遍采用输液器给患者用药。而现有输液器由于结构原因在输液结束时,由于拔针不及时等各种原因易出现血液反流的问题,因而给患者带来痛苦及危害,影响治疗效果。
发明内容
为了解决现有输液器在输液结束时易出现血液反流的问题。本实用新型提供一种防反流输液器。该防反流输液器能够在输液结束时防止血液反流现象产生。
本实用新型的技术方案是:该防反流输液器包括针头、输液管以及阀管。针头与输液管之间有阀管,阀管内下部有隔板,隔板上有1个以上通液孔,阀管内隔板上有阀球。
本实用新型具有如下有益效果:该防反流输液器由于采用针头与输液管之间有阀管,阀管内下部有隔板,隔板上有1个以上通液孔,阀管内隔板上有阀球结构。利用阀管和阀球组成单流阀,只能进液,在输液结束时阀球关闭,达到防止血液反流的目的。所以说该防反流输液器能够在输液结束时防止血液反流现象产生。
附图说明:
附图1是本实用新型结构示意图。
图中1-针头,2-输液管,3-阀管,4-隔板,5-通液孔,6-阀球。
具体实施方式:
下面结合附图对本实用新型作进一步说明:
如附图所示,该防反流输液器包括针头1、输液管2以及阀管3。针头1与输液管2之间有阀管3,阀管3内下部有隔板4,隔板4上有1个以上通液孔5,阀管3内隔板4上有塑料的阀球6。当常输液时,阀球6座在隔板4上,药液经隔板4上的通液孔5进入针头1;在输液结束时,患者血液推动阀球6堵在阀管3内与输液管2相连的口处,进而关闭血液不能外流,达到在输液结束时防止血液反流现象产生的目的。
