在病理组织包埋过程中有较多的石蜡油雾挥发,包埋时还需不断用酒精灯燃烧带有石蜡的镊子,产生一种石蜡燃烧时特有的黑烟,污染周围的环境。石蜡含有致癌物质,并有引起中毒性黑变病的可能,我们应尽量减少蜡雾和蜡燃烧时的悬烟侵入人体。为此,我科自己制作了一种排除石蜡油雾的简易装置,经过一年时间的使用,效果令人满意,现介绍如下。 In the pathological tissue embedding process more volatile paraffin oil mist, burial also need to continue to use alcohol lamp burning with paraffin tweezers, resulting in a paraffin-burning unique black smoke, pollute the surrounding environment. Paraffin waxes contain carcinogens and may cause toxic melanosis. We should try our best to minimize the intrusion of suspended tobacco into the human body when the wax fog and the wax burn. To this end, our department made a simple device to exclude paraffin oil mist, after a year of use, the results are satisfactory, are presented below.
