Dosing pump for pharmaceuticals, with anti-contamination protection

摘要

The device (2) has a fluid reservoir (1) with outlet (23). Air flows into the reservoir during fluid discharge, for pressure compensation. The air intake contains elements for sterilisation/germ killing/germ-reduction of the air. One section of the fluid outlet has similar separate elements to treat the outgoing fluid. The elements contains substances with oligo-dynamic or germ-reducing capabilities, e.g. a heavy metal and/or a heavy metal alloy, which is active in metallic and/or ionic form, and may be silver.
