Product History
Drain traps are a well known reservoir for facultative pathogens. Numerous publications report outbreaks associated with sink drains, some of which have lasted for years (z. B. Hota et al. 2009; Lowe et al. 2012; Gbaguidi-Haore et al. 2018 etc.)1,2,3.
1970s
As early as the 1970s, studies on the occurrence of Pseudomonas aeruginosa in sink drains were published, as well as related attempts to reduce the bacteria in the drain by means of heating (z. B. Kohn 1970; Mäkelä et al. 1972; Ayliffe et al. 1974)4,5,6.
1970s
1991
In 1991, during a four-week prospective epidemiological study at the University Children's Hospital in Tübingen, Germany, it was discovered that P. aeruginosa genotypes isolated from drains were also present on the hands of staff. This suggested a route of transmission from drains to hands via aerosols. To prevent bacterial growth in sink drains, sink drains were heated up to 70 °C. This prevented not only bacterial growth in the drains but also P. aeruginosa aerosol formation, which in turn precluded transmission to the hands of medical staff when washing hands.7
1990s
These investigations were followed by initial development work on a self-disinfecting drain trap, with the aim of completely preventing biofilm formation and emission of pathogens on a permanent basis. These finally led to a safe and validatable disinfection system, which was successfully tested for the first time under the name "Biorec".
1990s
2002
Starting in 2002, a long-term study was conducted at the Oberlausitz-Klinikum Bischofswerda. Pathogen statistics and the survey of nosocomial infections showed a significant decrease in patient colonization and the occurrence of nosocomial infections after the installation of the Biorec disinfection devices.8,9
