De­vel­op­ment of a clean­ing method for the safe and eco­nom­i­cal re­moval of high­ly ef­fec­tive drugs on sur­faces in hos­pi­tals using cy­to­tox­i­cs as an ex­am­ple

AiF 13711 N

Sub­ject of the pro­ject which was car­ried out in co­op­er­a­tion with the in­sti­tute for en­er­gy and en­vi­ron­men­tal tech­nol­o­gy (IUTA) was the re­moval of residues of cy­to­tox­i­cs (an­ti­cancer drugs) from floors with pro­tec­tive lay­ers which have to ad­sorb the cy­to­tox­i­cs and work against en­train­ment. Cur­rent­ly known tem­po­rary pro­tec­tive lay­ers on elas­tic floor­ings were de­vel­oped under the point of view of the op­ti­mi­sa­tion of care prop­er­ties and the min­imi­sa­tion of re-soil­ing. These lay­ers are used to in­crease the re­sis­tance of floors against cleansers and other sub­stances and ad­di­tion­al­ly they have to in­crease the re­sis­tance against abra­sion and/or they’re used as pro­tec­tive lay­ers for the spe­cif­ic abra­sion. In order to avoid a neg­a­tive im­pact on the op­ti­cal ap­pear­ance of the floor­ings, all in­gre­di­ents had to be trans­par­ent and had to form a ho­mo­ge­neous film. Re­gard­ing the ad­he­sion of the films, the swelling ca­pa­bil­i­ty of the coat­ing must be taken into ac­count, which leads to changes of the sur­face prop­er­ties in the case of tem­per­a­ture and hu­mid­i­ty vari­a­tions.

We thank the Ar­beits­ge­mein­schaft in­dus­trieller Forschungvere­ini­gun­gen “Otto von Gu­er­icke” e.V. (AiF) (As­so­ci­a­tion of In­dus­tri­al Re­search Or­gan­i­sa­tions) (AiF-No. 13711 N) for fund­ing these pro­jects through a fi­nan­cial sup­port by the Fed­er­al Min­istry of Eco­nom­ic Af­fairs.

Fur­ther­more we would like to thank dif­fer­ent mem­ber com­pa­nies for sup­port­ing the in­ves­ti­ga­tions.


The re­search re­port is avail­able on re­quest from FRT.
