Abstract

本实用新型公开了一种输液器进气管，由穿刺针、连接导管、空气过滤器组成，其要点在于在连接导管上设置一个带针座的液体过滤器，液体过滤器与连接导管为活动连接。本实用新型具有结构合理、操作简单等优点，向输液瓶内加注药液时，将进气管下部的连接导管从液体过滤器的针座处拔下，将注射器插入针座，药液通过液体过滤器进入输液瓶，使药液得以过滤，并避免了输液瓶瓶塞的反复穿刺。

Description

一种输液器进气管
技术领域本实用新型属于护理医疗器具技术领域，涉及一种输液器进气管。
背景技术现有技术的输液器进气管，依次由穿刺针、连接导管、空气过滤器组成，输液时由穿刺针穿过瓶塞，进入输液瓶内只起进气作用。在向输液瓶中加注药液时，再用注射器穿过瓶塞加入输液瓶中，由于药液未经过过滤，易将玻璃碎屑及瓶塞上的橡皮屑带入药液中，引起输液并发症。
发明内容本实用新型要解决的技术问题是，向输液瓶中加注药液未经过滤的问题，从而提供一种向输液瓶中加注药液使药液过滤的输液器进气管。
为解决上述技术问题，本实用新型的技术方案是：以现有输液器进气管为基础，由穿刺针、连接导管、空气过滤器组成，其要点在于在连接导管上设置一个带针座的液体过滤器，液体过滤器与连接导管为活动连接。
为避免穿刺针穿刺瓶塞时将橡皮屑带入药液中，所说穿刺针的出气孔在穿刺针体的一侧。
本实用新型具有结构合理、操作简单等优点，向输液瓶内加注药液时，将进气管下部的连接导管从液体过滤器的针座上拔下，将注射器插入针座，药液通过液体过滤器进入输液瓶，使药液得以过滤，并避免了输液瓶瓶塞的反复穿刺。
附图说明附图为本实用新型结构示意图。
具体实施方式根据附图，本实用新型依次由穿刺针1、连接导管2、5和空气过滤器6组成，在连接导管2上增设一个带针座4的液体过滤器3，液体过滤器3与连接导管2、5为活动连接。向输液瓶内加注药液时，将注射器插入针座4，药液通过液体过滤器3进入输液瓶，向输液瓶加注药液后再将下部的连接导管5与针座4连接。

Claims (2)
