Description

胃液PH值检测装置
技术领域
本实用新型涉及医疗器械领域，详细地讲是一种胃液PH值检测装置。
背景技术
众所周知，胃病患者需经常进行胃液PH值检测，一种方法是将吸液管从胃镜栓孔中伸入胃腔，用注射器吸取胃液，但其操作复杂，并且患者痛苦大；另一种方法是，将化学试剂加入负压瓶中，与胃液产生化学反应，根据试纸颜色的变化估算胃液的酸度，这种方法准确性不高，不能直接测定胃液的PH值，结构复杂，并且不易操作。
发明内容
为了克服现有技术的不足，本实用新型提供一种胃液PH值检测装置，结构简单，易于操作，可直接测定胃液的PH值，并且准确性高。
本实用新型解决其技术问题所采用的技术方案是：一种胃液PH值检测装置，设有阀体，阀体采用三通阀式结构，阀体的中部开口为圆锥式塞孔，塞孔内安装有圆锥式阀塞，阀塞经定位键与塞孔上的定位槽定位，阀塞上加工有凹槽，凹槽与阀塞顶部的出液孔相连通，出液孔上安装有单向阀。
本实用新型的有益效果是，结构简单，易于操作，可直接测定胃液的PH值，并且准确性高。
附图说明
下面结合附图和实施例对本实用新型进一步说明。
图1，本实用新型的结构示意图。
图中1.阀体，2.阀塞，3.阀顶，4.出液孔，5.定位槽，6.定位键，7.PH值试纸、8.凹槽、9.直通孔，10.锥形接头，11.塞孔。
具体实施方式
在图1中，本实用新型设有阀体1，阀体1采用三通阀式结构，阀体1横向为直通孔9，直通孔9两端分别安装有一个阶梯式锥形接头10，阀体1的中部开口为圆锥式塞孔11，塞孔11内安装有圆锥式阀塞2，阀塞2经定位键6与塞孔11上的定位槽5定位，阀塞2上加工有凹槽8，凹槽8内设有PH值试纸7，阀塞2顶部为阀顶3，阀顶3上加工有出液孔4，凹槽8与出液孔4相连通，出液孔4上安装有单向阀，单向阀的作用是液体只能从凹槽8进入出液孔4，并阻止空气经出液孔4进入凹槽8。
本实用新型当需要对患者的胃液进行检测时，将阀体1两端的阶梯式锥形接头10安装在胃镜与负压瓶之间，旋转阀塞2，则胃液经凹槽8流向出液孔4，并与凹槽8内的PH值试纸7接触，PH值试纸7与胃液发生化学反应并变色，从而可直接准确地显示出胃液的PH值。
