Description

输液排气阀
技术领域
本实用新型涉及医疗器械技术领域，具体的来说涉及一种输液排气阀。
背景技术
医用输液器，一般用于给患者静脉注射用。一般使用时，输液瓶高置，输液器一端插入输液瓶中，另一端插入患者体内静脉，将药液注入患者体内的静脉循环。输液开始时，输液器管中除液体之外往往含有气体，在输液时，有时输液器内空气未排尽，有时在静脉输液前，需要静脉推射药液，推射完毕需要将输液器接回输液管，此时输液管内会混有空气；或者静脉输液前需要静脉抽血，抽血完毕，输液器接回输液管，也会混有空气；气体注入患者静脉内是非常有害的，对健康十分不利。
实用新型内容
本实用新型所要解决的技术问题在于，克服现有输液器中易混入气体的缺点，提供一种输液排气阀。
为了解决上述问题，本实用新型的技术方案是这样的：
一种输液排气阀，包括阀体，设置在阀体上连接输液器管路的上下接口，以及设置在阀体上排出输液器内气体的出气口，其特征在于，所述阀体内具有阀心，所述阀心内具有三个互相导通的径向通道，所述阀心还具有与三个径向通道相通的轴向通道，所述轴向通道在排气状态下连通出气口，所述阀心一端固定连接一阀心旋钮。
所述三向导通的径向通道，其中两向为输液通道，且成直线布置，另一向通道为排气通道，且排气通道垂直两向输液通道，三向通道在交接处与轴向通道导通。
所述阀心在出气口处具有连接轴向通道与出气口的连接通道，所述连接通道与排气通道在阀心截面上的投影为直线。
有益效果，本实用新型可以有效的避免输液过程中产生的气泡，保证了输液过程中患者的输液安全，结构简单，安装方便，使用便捷。
附图说明
下面结合附图和具体实施方式来详细说明本实用新型；
图1为本实用新型输液排气阀的输液状态结构示意图。
图2为本实用新型输液排气阀的排气状态结构示意图。
图3为本实用新型输液排气阀的A-A截面示意图。
图4为本实用新型输液排气阀的B-B截面示意图。
图5为本实用新型输液排气阀的输液状态液体流向示意图。
图6为本实用新型输液排气阀的排气状态气体流向示意图。
具体实施方式
为了使本实用新型实现的技术手段、创作特征、达成目的与功效易于明白了解，下面结合具体图示，进一步阐述本实用新型。
参看图1-图4，一种输液排气阀，包括阀体1，所述阀体1上具有连接输液器管路的上下接口2、3，所述阀体1上还具有排出输液器内气体的出气口4，所述阀体1内具有阀心6，所述阀体1的一端固定连接一阀心旋钮5，所述阀心6内具有三个互相导通的径向通道，所述阀心6还具有与三个径向通道相通的轴向通道61，所述三向导通的径向通道62、63、64，其中两向为输液通道62、63，且成直线布置，另一向通道为排气通道64，且排气通道64垂直两向输液通道62、63，三向通道在交接处与轴向通道61导通，所述轴向通道61在排气状态下连通出气口4。
所述阀心6在出气口4处具有连接轴向通道61与出气口4的连接通道65，所述连接通道65与排气通道64在阀心6截面上的投影为直线。
参看图5，当输液进行时，输液通道62、63与输液管路的上下接口2、3连通，液体顺畅的从阀体内流过，排气通道64被阀体堵住无法连接输液管路，此时与轴向通道61连接的连接通道65被阀体堵住，无法连接出气口4。
参看图6，当输液器排气时，将旋钮旋转90度，此时排气通道64连通输液管路的上接口此时与轴向通道61连接的连接通道65连接出气口4，气体由排气通道64进入轴向通道61，再经连接通道65由出气口4排出，此时输液通道62、63被阀体堵住无法连接输液管路。当排气完毕时，将旋钮回旋转90度即恢复输液。
本实用新型可以有效的避免输液过程中产生的气泡，保证了输液过程中患者的输液安全，结构简单，安装方便，使用便捷。
以上显示和描述了本实用新型的基本原理、主要特征和本实用新型的优点。本行业的技术人员应该了解，本实用新型不受上述实施例的限制，上述实施例和说明书中描述的只是说明本实用新型的原理，在不脱离本实用新型精神和范围的前提下本实用新型还会有各种变化和改进，这些变化和改进都落入要求保护的本实用新型范围内。本实用新型要求保护范围由所附的权利要求书及其等同物界定。
