In recent times there has been more and more awareness of the role that water and its hygiene play in the transmission of pathogens.

Today, for example, it is known that hospital drains are a very important reservoir of pathogens, 7,8,9, it is also known that the siphons under the sinks in hospitals are another open reservoir of pathogens and a continuous source of germs, these they contain an average of 10 5-10 10 CFU/ml of bacteria, including 10 3-10 6 CFU/ml of gram-negative bacilli. 1,2,3

When water enters the siphon, aerosols form on the surface of the sealing liquid, which can emit germs up to a radius of 1.5 meters from the siphon. In case of bacterial contamination of the sealing fluid with >10 5 CFU/ml, so many microorganisms enter the room air that a measurable transfer of germs from the sealing fluid to the hands of the patient or nursing staff occurs. 2,5,6

As for drains, they are very prone to accumulating bacteria and other pathogens due to the fluids that pass through them. If these are not kept clean and disinfected, they will become a reservoir of microorganisms that cause nosocomial infections.

Biogen Technologies has developed H2O Flusher that, although on the one hand it has a practicable drain that allows it to be disinfected, on the other hand it has an absolutely watertight non-return valve that prevents the emission of germs present in the siphon from the sealing liquid.
