粉碎机是药物粉碎常用的设备。我院使用的粉碎机是万能粉磨机,该类机器在使用中会出现齿柱的缺损或断落,严重时会导致机器的报废。分析其损坏原因主要有:一、被粉碎药物中混有金属物如铁块、铁针或石块等,因异物硬度大,容易造成齿柱的硬损伤。二、没有掌握好进药量,进药过多,容易造成齿柱的超负荷,特别是粉碎硬度较大的药物时如玉金等,超负荷粉碎时极易使齿柱断裂。三、对一些不宜粉碎的药物强行粉碎如虎杖等,其结果在瞬间能使内、外两盘上的金属齿变形或外盘齿大面积的断落,更甚者也可因药物或断落、变形的金属具卡在其它具间隙中,引起高速旋转的内盘骤停导 Crushers are commonly used equipment for drug crushing. The pulverizer used in our hospital is a universal pulverizer. In the use of such machines, there will be defects in the dentition or breakage of the dentition. In severe cases, the machine will be scrapped. Analysis of the causes of damage are: First, the crushed drugs mixed with metal objects such as iron, iron or stone, etc., due to the hardness of foreign bodies, easily lead to hard tooth column damage. Second, it is difficult to master the amount of drug, too many drugs, easily lead to overload of the dentition, especially when crushing drugs with higher hardness, such as jade gold, etc. Third, some drugs that should not be crushed are forcibly crushed, such as the knotweed, and the results can instantaneously cause the metal teeth on the inner and outer trays to be deformed or the outer disc teeth to be broken off. Even worse, it can also be caused by drugs or breaks. The deformed metal jig stuck in other gaps causing high-speed rotation of the inner disc stop.
