Abstract

本实用新型涉及一种医疗器具。公知的各种安全输液器,都十分复杂,成本也较高,不太理想。本实用新型提供一种由传统输液器及浮球组成的安全输液器,其特征是:在原输液器内设置一无毒塑料空心浮球,浮球下部设置一瓶塞式的圆柱体,其直径与输液器下管道内壁相密闭配合。当所输液体快完时,随着输液器内液面降低,浮球即下沉堵塞封闭输液器管口,不致让空气进入输液针头,余液有一定重力以防止血液回流,起到安全输液的作用。

Description

安全输液器
技术领域
本实用新型涉及一种医疗器具。
背景技术
目前,公知的各种安全输液器,都十分复杂,成本也较高,不太理想。
发明内容
为了克服上述不足,本实用新型提供一种安全输液器,就能达到结构简单、成本低廉的目的。
本实用新型解决其技术问题的技术方案是:由传统输液器及浮球组成的安全输液器,其特征是:在原输液器内设置一无毒塑料空心浮球,浮球下部设置一瓶塞式的圆柱体,其直径与输液器下管道内壁相密闭配合。当所输液体快完时,随着输液器内液面降低,浮球即下沉堵塞封闭输液器管口,不致让空气进入输液针头,余液有一定重力以防止血液回流,起到安全输液的作用。
本实用新型的有益效果是:结构简单、使用方便、成本低廉、保证输液安全效果好。
附图说明
下面结合附图和实施例对本实用新型作进一步说明:
图1为本实用新型结构示意图。
图中1.原输液器,2.浮球。
具体实施方式
在图1中,在原输液器(1)内设置一无毒塑料空心浮球(2),浮球下部设置一瓶塞式的圆柱体,其直径与输液器下管道内壁相密闭配合。当所输液体快完时,随着输液器内液面降低,浮球即下沉堵塞封闭输液器管口,不致让空气进入输液针头,余液有一定重力以防止血液回流,起到安全输液的作用。
