    • Objects for use in medical application that are produced from plastics required to have an antimicrobially effective content of metals (or metal compounds) can be produced inexpensively by coating a plastic blank in the form of film, granules or fibers with the desired metal (or metal compound) according to the methods used in thin-film technology. The thus obtained intermediate is subsequently comminuted and mixed and, as the starting product for the desired final form, further processed. As a result, these objects are antimicrobially effective on every area of their surface, i.e. also on internal surfaces. The amount necessary for full effectiveness of the antimicrobially active substances, which in the case of the subject-matter of this invention are oligodynamically active metals (or metal compounds), is only a small percentage of that necessary when they are introduced into the plastic in the form of powder, which fact results in considerable financial advantages.
    • 可以通过用所需金属(或金属(或金属)形式的薄膜,颗粒或纤维的形式涂覆塑料坯料,廉价地制造由塑料制成的用于医疗应用的用于具有抗微生物有效成分的金属(或金属化合物)的物体 化合物)根据薄膜技术使用的方法。 随后将如此获得的中间体粉碎并混合,并作为所需最终形式的起始产物进一步处理。结果,这些物体在其表面的每个区域,即内表面上都是抗微生物的。 在本发明的主题为非动力活性金属(或金属化合物)的情况下,抗微生物活性物质的完全有效性所需的量只有当它们被引入塑料时才是必需的一小部分 粉末的形式,这实际上带来了相当大的财务优势。
