Treating surface of fluid product distribution device, by modifying surface by ionic implantation using multicharged and multi-energy ion beam, where product is pharmaceutical fluid intended to be sprayed and/or inhaled nasally/orally

摘要

The process for treating a surface of a fluid product distribution device, comprises modifying a surface to be treated by ionic implantation using multicharged and multi-energy ion beam. The modified surface has properties that limit the formation of a biofilm and prevent the occurrence and/or proliferation of bacteria. The ion beam is created by an electron cyclotron resonance source. The surface to be treated is made of a synthetic material, elastomer, glass or metal. The ionic implantation is carried out at a depth of 0-3 mu m.
