从事检验工作的同志,经常使用一些量器,来准确的测量液体的体积。而各种容量的吸管使用的机会特别多,通常使用吸管的方法都是用口吸法。然而口吸法常因技术不佳或精神不集中而误将液体吸入口内,可引起各种不良后果。如:感染、腐蚀、甚至生命危险。消灭口吸法的缺点是很必要的。有见于此,近年来,我们使用了一种简单液体吸引器,能较圆满地达到上述目的。今介绍如下,请同志们指正。一、吸引器结构:
Comrades engaged in inspection work, often use some measuring device to accurately measure the volume of liquid. The various capacity of the straw there are particularly many opportunities to use, usually using the straw are the method of mouth suction. However, the suction method often due to poor technology or lack of concentration and mistakenly inhaled liquid, can cause a variety of adverse consequences. Such as: infection, corrosion, and even life-threatening. The shortcomings of the elimination of suction method is necessary.
