日本 CC—108型血球计数器配套用的 AD—240自动稀释器,使用中由于稀释液内易存在一些毛状物,经常堵塞,造成稀释比例不正确或不能进行自动稀释。需要修理人员打开机壳,取出机内管路中的两个过滤器清除过滤网上的堵塞物,才能重新正常使用。这样维护既麻烦,又影响正常的临床使用。为此对该稀释器的吸液口做了一点改进。用有机玻璃做一个喇叭状的过滤器外壳(图1),中间装一块与其相适宜的喇叭状海绵,使两者密封牢固。把 Japan CC-108 hematology counter supporting the use of AD-240 automatic diluter, due to the use of dilute liquid easily exist some hair, often blocked, resulting in the dilution ratio is incorrect or can not be automatically diluted. Need to repair personnel to open the case, remove the two filters in the pipeline to remove clogs on the filter, in order to resume normal use. This maintenance is both troublesome, but also affect the normal clinical use. To this end, the dilution of the liquid suction port made a little improvement.
