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.
A method for producing antimicrobial plastic bodies, comprising the steps of:
A method of producing plastic bodies, comprising the steps of coating a plastic blank with at least one antimicrobially active metal or metal compound by means of a chemical or physical method, processing the coated plastic blank by at least one of comminuting and melting down, and subsequently giving the plastic a desired shape,
