A contact-free, shapely dispenser system for dental and medical offices. One-way 500 ml bottles with one-way pumps contain liquid soap or hand disinfection. A battery-operated infrared sensor is activated by approaching your hand and dispenses an adequate portion into your hand. Contact-free operation and avoidance of refilling and cleaning the dispenser, which was the common proceeding up to now, meet the latest hygienic guidelines of the Robert Koch Institute. Hygenius fits in the existing drill holes of conventional dispenser systems on worktops. Different versions like a mobile or a wall-mounted dispenser are available.
