Description

一种液体样本等分仪 技术领域
本发明一种液体样本等分仪涉及一种能够对检测用体液进行等量样本分配的等分仪，属于医疗器械领域。
 背景技术
目前，在对人体检测使用的液体样本采集后，由于检测的项目不同，需要将检测液体分配为等量的多个样本，有的需要进行长时间的观察研究，要务必确保定量的分配，现有的都是采用滴管进行，效率低下，单一的进行采集定量。
 技术解决方案
为了改善上述情况，本发明一种液体样本等分仪提供了一种能够对液体样本分配成多个等分样本的等分仪，效率高，分配定量精度高。
本发明一种液体样本等分仪是这样实现的：本发明一种液体样本等分仪由夹持板，刻度尺,主导出管，辅导出管，连通挂环，支撑板，胶管，支撑座，螺杆，导向块，贯穿槽，螺套和封闭杆组成，夹持板置于支撑座上，夹持板上开有多个卡槽，多个支撑板对应置于夹持板上，且和卡槽对应，所述支撑板位于卡槽外缘，夹持板的两端开有贯穿槽，夹持板的端部开有贯穿孔，所述贯穿孔和卡槽连通，螺杆置于贯穿孔内，封闭杆置于螺杆上，且和卡槽侧壁切合，导向块套置于封闭杆上，且位于贯穿槽内，螺杆和夹持板之间设置有螺套，封闭杆和夹持板之间置有导向套，刻度尺垂直置于夹持板上，且和卡槽对应，主导出管、辅导出管通过胶管相连通，连通挂环置于连接点，连通挂环卡置于支撑板上沿，胶管卡置于卡槽内，主导出管、辅导出管为透明管材，且口部为斜切口。
 有益效果
一、能够进行燃气灶上方支托。
二、翻转收纳，能够对明火进行格挡。
三、垫板直接配合燃气灶加热进行烹饪。
 附图说明
图1为本发明一种液体样本等分仪的立体结构图。
图2为本发明一种液体样本等分仪的结构示意图。
图3为本发明一种液体样本等分仪主体框的立体结构图。
附图中其中为：夹持板（1），刻度尺（2）,主导出管（3），辅导出管（4），连通挂环（5），支撑板（6），胶管（7），支撑座（8），螺杆（9），导向块（10），贯穿槽（11），螺套（12），封闭杆（13）。
 本发明的实施方式
本发明一种液体样本等分仪是这样实现的：使用时，将液体样本从主导出管（3）导入，由于主导出管（3）、胶管（7）、辅导出管（4）相互连通，注入主导出管（3）内的液体液位上升，使得主导出管（3）、辅导出管（4）内的液位等高，通过刻度尺（2）观察液位高度，然后旋转螺杆（9），螺杆（9）推压封堵杆，对胶管（7）进行加压，使得胶管（7）受力闭合，此时胶管（7）和主导出管（3）、辅导出管（4）断开，然后翻转将主导出管（3）、辅导出管（4）内的液体导出至不同的容器内，所述主导出管（3）、辅导出管（4）数量为多个，且能够形成连通，进行多组等量的分配。
所述主导出管（3）、辅导出管（4）口部斜向开口能够便于液体的倾倒。
所述胶管（7）能够被夹紧形成闭合，将液体分成三段，便于定量。
达到对液体样本进行等量分配的目的。
