Fight against hospital germs

NP® protected textile surfaces in the healthcare sector: sensational microbiological results without the use of biocides!

nanopool targeted to improve the protection against infectious diseases and multi-resistant hospital germs. In case of the increasing medical- nursing tasks in hospitals and other institutions, established measures in the hygiene sector should be continuously improved in case of hospital germs.

Microbiological examination of NP® coated textiles in hospitals – a passive coating as option to prevent microbial resistances towards biocides.

Employees of Danish research institutes investigated the cleaning potential of hospital furniture having NP®-coated textiles.

In the waiting room at the outpatient lung department, microbiological swab tests have been taken from different arm rests of chairs within a pre-set test period (plastic (reference), wool. Polyester) to determine the number of hospital germs.

The hands of the patients are in direct contact with the armrests of the chairs, what represents the biggest risk for cross contamination. The specific premises offered a broad patient mix and an ongoing flow of patients, and this constant people traffic was important to have all the different chairs frequently in use.

Results of surfaces that reach an acceptable bacteria level

Material Before cleaning After cleaning
Polyester – unprotected 0% 50%
Polyester – NP® protected 62.5% 100%
Wool  – unprotected 37.5% 62.5%
Wool – NP® protected 37.5% 100%
Plastic (reference – unprotected) 25% 25%

This case study about the effect of passive coating for the cleaning potential of upholstery showed a considerable difference between the tested surfaces. Only those textiles treated with the special NP® product were able to be cleaned to an acceptable level below the critical limit value of 2,5 CFU / cm². Neither the conventional textiles, nor the regular armrest made of plastic could be cleaned to achieve that level.

This allows to offer a microbial protection without the risk of bacteria and microorganisms form resistances against biocides used.

Furthermore, this also allows to use conventional upholstery in hospitals, what benefits the hospital design and the healing process / recovery of the patients, as the physical environment influences the patients’ healing process.
