Description

一种医用三联三通组合注射器具
技术领域
本发明涉及医用注射器具技术领域，尤其涉及一种医用三联三通组合注射器具。
背景技术
目前，医务人员在使用三联三通等组合注射器具为患者进行注射造影剂时，在注射器内部常会有危害患者生命安全的气泡出现，由于在为患者注射过程中采取中断注射等方法来排除空气，步骤繁琐，操作不便。
发明内容
本发明要解决的技术问题是如何克服现有技术的不足，提供一种医用三联三通组合注射器具。
本发明为实现上述目的采用的技术方案是：一种医用三联三通组合注射器具，包括注射器、三联三通、注射软管，所述三联三通的一端安装在所述注射器的乳头端，所述注射软管的一端与所述三联三通的另一端相连接，所述注射器的活塞内部沿活塞杆方向设有若干通孔，所述注射器的活塞末端覆盖有 TPU防水透气膜，所述通孔位于所述TPU防水透气膜的覆盖范围内。
进一步地：所述TPU防水透气膜的面积大于所述通孔的面积。
进一步地：所述通孔至少有两个。
本发明的优点在于在不拆除注射装置的状态下，快速将存留在注射器内部的气体排出，本发明结构简单，便于制作，操作简便。
附图说明
图1本发明整体结构示意图。
图2本发明插针机构示意图。
具体实施方式
一种医用三联三通组合注射器具，包括注射器1、三联三通2、注射软管3，所述三联三通2的一端安装在所述注射器1的乳头端，所述注射软管3的一端与所述三联三通2的另一端相连接，所述注射器1的活塞11内部沿活塞杆14 方向设有若干通孔12，所述注射器1的活塞末端覆盖有TPU防水透气膜13，所述通孔12位于所述TPU防水透气膜13的覆盖范围内。
所述TPU防水透气膜13的面积大于所述通孔12的面积，所述通孔12有三个。
在使用时，若注射器1内部出现气泡，只需将注射器1倾斜，轻微用力按压注射器1的活塞，便能够快速将气体排出。
上述实施例只是为了说明本发明的技术构思及特点，其目的是在于让本领域内的普通技术人员能够了解本发明的内容并据以实施，并不能以此限制本发明的保护范围。凡是根据本发明内容的实质所作出的等效的变化或修饰，都应涵盖在本发明的保护范围内。
