在医院的化验分析设备中,用于人体血液钾、钠含量分析的火焰光度计是使用比较频繁的一种仪器。但由于仪器工作时标本需由操作员一个一个试管地送入,因而操作极不方便。为改变这种状况,我们设计了如图所示的小装置,减轻了劳动强度,提高了工作效率。操作时,把配制好的标本试管按序号插入该装置试管盘后,用手转动试管盘。试管盘上的定位槽在定位片及手的旋转压力作用下使试管盘向下移动,仪器采样吸管就退出
In the hospital laboratory analysis equipment, human blood potassium, sodium analysis of the flame photometer is the use of a more frequent instrument. However, the operation of the instruments is extremely inconvenient as the specimens are fed by the operator one by one in a test tube. To change this situation, we designed a small device as shown in the figure, which reduced labor intensity and increased work efficiency. Operation, the preparation of a good sample tube according to the serial number of the test tube into the device, turn the test tube by hand. Test tube plate positioning groove in the positioning plate and the hand under the pressure of the rotation of the test tube tray down, the instrument sampling straw to exit
