MoveoSiphon - Model ST24 - Disinfection System for Sink Drains
Odour traps are commonly known germ reservoirs and origin of the transmission of pathogens and patient colonization. Practical solutions to exclude the odour trap as pathogenic source did not exist for a long time.
Sink drains under wash basins in clinics and hospitals are open pathogen reservoirs and sources for emitting bacteria.1,2,3 They contain on average 105-1010 CFU/ml of bacteria, including 103 - 106 CFU/ml of gram-negative rods.4
Water ?owing into the sink drain produces aerosols on the surface of the seal water which can emit the bacteria up to a distance of 1.5 metres around the siphon.5
In case of bacterial contamination of the seal water of >105 CFU/ml so many microorganisms are carried into the air in the room that a measureable transmission of bacteria from the seal water to the hands of patients or staff takes place.2,6
Numerous clinical investigations prove:
conventional sink drains do not ful? l the high hygiene standards needed in invasive intensive care.4,5
The thermo disinfection carried out by the MoveoSiphon ful?ls at least the standards of the technical process of pasteurization by means of heating (10 to 15 seconds at 85°C). In the process the unit heats up to the set tem-perature (85°C) and slowly cools down while the subsequent vibration cleaning takes place.
Once the minimum set temperature has been reached (75°C), the heating process and thus the disinfection cleaning cycle recommence once again.
If no interruption is caused by additional water in? ow, then the entire process is completed after 5-6 cycles in a period of approximately one hour and the MoveoSiphon switches into standby mode until water ? ows in again.
Odour traps are commonly known germ reservoirs and origin of the transmission of pathogens and patient colonization. Practical solutions to exclude the odour trap as pathogenic source did not exist for a long time.
To prevent the bacterial growth in drain pipes Prof. Döring and his employees did some tests at university hospital in Tübingen. They heated the drain pipes up to 70 degrees and succeeded in getting the hands of the staff free from P. aeruginosa cultures after hand washing.1 In the 90s opportunities were sought for the disinfection of wash basins (odour traps) of mucoviscidosis patients but the thermal disinfection turned out to be uncontrollable and the use of peracetic acid too cost-intensive.2
In 1996 Dr. Schluttig (Biorec/Lauta) started the development of a self-disinfecting odour trap aiming at the prevention of biofilm formation and bioaerosol formation. The result of this development was a safe and validated disinfection system: the medical hygiene siphon Biorec.
First successful tests of the Biorec-system took place at the university hospital Tübingen in 1999.2
In 2002 a long-term study was carried out at the “Oberlausitz-Klinikum Bischofswerda”. The pathogen statistics and the data collection of nosocomial infections showed a significant decrease in patient colonization and occurrence of nosocomial infections after the installation of the Biorec devices.3,4
Even tests at a neonatal intensive care unit showed that the combination of continuous thermal disinfection with low frequency vibration of the Biorec hygiene siphon prevents the biofilm formation and eliminates the siphon as bacterial reservoir. Thus, the Biorec hygiene siphon is an efficient technology that stops the airborne transmission of nosocomial pathogens by odour traps.5
In 2004 the hygiene siphon was integrated in the Water Safety Plan of the University Hospital of Greifswald.6
Since 1st September 2012 the hygiene siphon is manufactured and refined by MoveoMed GmbH in Radebeul nearby Dresden. The sonothermal disinfection system is since then marketed under the brand name “MoveoSiphon“. Several publications and case reports from hospitals in Germany, The Netherlands and Canada document the effective operation (see Downloads).
