Description

一种非重力输液器
技术领域
本发明涉及输注医疗器械领域，具体涉及一种非重力输液器。
背景技术
输液是医疗过程中常见常用的医疗手段，在输液过程中，常常无法避开重力的困扰，无法在特殊环境中使用。现有的非重力输液装置多采用挤压药囊的形式，需要将现有输液瓶内药液先注入药囊中，且更换药液时要重新灌注药囊，步骤繁琐，药囊内药液剩流较多，造成药液浪费和用药剂量不易控制。
发明内容
本发明提供一种非重力输液器，所述的一种非重力输液器可以充分应用现有输液器部件，输液速度稳定，换液方便。
本发明所述的一种非重力输液器，包括穿刺器、储药腔体和两个筒体；所述两个筒体内设置有胶塞，胶塞下部连接推杆；所述两筒体的上端通过管道分别与储药腔体上端和穿刺器下端联通；所述两筒体与储药腔体间的管道间分别设置有使药液只向储药腔体方向流动的单向阀，所述两筒体与穿刺器间的管道间分别设置有使药液只向筒体方向流动的单向阀。
所述储药腔体内固定设置有止液膜，当输液过程即将结束，液面下降到止液膜时，止液膜防止空气进入止液膜以下进而流入储药腔体下连接的输液导管，又可起到药液过滤功能。
所述单向阀为鸭嘴状的弹性塑胶阀。
本发明所述的一种非重力输液器在使用时，穿刺器插入药液瓶内，在储药腔体下端连接输液管，两推杆连接输液动力器，输液动力器可以使胶塞在筒体内上下往返运动。初始时，两胶塞都处于筒体的顶部；当输液动力器运行时，推拉左右两侧筒体内的胶塞做往返推拉运动，一个抽取药液瓶内药液，一个推出药液，同时运行。筒体内的胶塞向外拉表示筒体正在吸入药液。当筒体内的胶塞向内推的时候，表示药液正在被推出而进入储药腔体，储药腔体中有止液膜，防止空气流入储药腔体下端连接的输液导管而进入人体。
本发明所述的一种非重力输液器结构简单，造价低，输液时药液输入较为完全，更换药液简单。
附图说明
图1为本发明的结构示意图。
具体实施方式
以下结合附图，对本发明的具体实施方式作进一步说明：
如图1所示，本发明所述的一种非重力输液器，包括穿刺器1、储药腔体2和两个筒体3；储药腔体2内固定设置有止液膜4；所述两个筒体内设置有胶塞5，胶塞5下部连接推杆6；所述两筒体3的上端通过管道7分别与储药腔体2上端和穿刺器1下端联通；所述两筒体3与储药腔体2间的管道7间分别设置有使药液只向储药腔体2方向流动的鸭嘴状的弹性塑胶阀单向阀8，所述两筒体3与穿刺器1间的管道7间分别设置有使药液只向筒体3方向流动的鸭嘴状的弹性塑胶阀单向阀8。
