创新背景

医院环境中微生物无处不在,但很多场景下医院都需要保持高度清洁的无菌环境,研发相关的材料有助于提高医疗卫生水平。

 

创新过程

芬兰国家技术研究中心(VTT)、于韦斯屈莱应用科学大学、芬兰中部医疗保健区和一家公司在2021年联合在于韦斯屈莱的芬兰中部中央医院进行了一项测试,发现木质化合物可以作为医疗环境中塑料用具的替代品,它具有良好的安全环保抗菌性能。
医院病房的窗帘必须具有抗菌特性,能够杀死微生物并抑制其生长。研究团队在医院进行了为期两个月的随访测试,对比用木皮单宁处理的窗帘织物中的微生物数量和以往医用窗帘的微生物数量,发现单宁水平使窗帘中的细菌减少了60%,证明树脂和木皮单宁是具有实用性的抗菌化合物。

研究发现轻微润湿单宁涂层可以增强它的有效性,改善细菌和单宁之间的接触。通过采用医院中使用的几种表面材料对比测试涂层区域和未涂层表面,研究证实了木质单宁和树脂防污和易于清洁的功能性和耐用性。医院进行的卫生测量表明,涂层区域的卫生水平比未涂层控制表面高出32%。

此外,研究还涉及测试紫外线相机技术,使用紫外敏感相机观察到表面上杂质的增加,评估涂层表面的清洁度。紫外相机技术可以在许多不同的表面上识别污点,即使在正常房间照明条件下看不到的可见杂质也会被该技术识别出来。测试进行在学校建筑门把手上,用紫外线相机拍摄的门把手样品的照片显示,即使看起来很干净的门把手也积聚着污染物,污垢和抗菌涂层在恶化。

研究有效证明了树脂和木质单宁在医院环境中作为抗菌涂层的可用性,将进一步开发相关的材料和成品,帮助医院使用清洁无害可降解的涂层。

 

创新关键点

将树脂和树皮与医院使用的抗菌材料进行对比,考虑木质涂料的可用性。

 

The use of wood coatings can reduce microorganisms on hospital surfaces

The Finnish National Centre for Technology Research (VTT), the Jyväskylä University of Applied Sciences, the Central Finland Healthcare District and a company in 2021 jointly conducted a test at the Central Finland Central Hospital in Väskjöllkray and found that lignon compounds can be used as an alternative to plastic appliances in medical environments, and it has good safe and environmentally friendly antibacterial properties.

Curtains in hospital wards must have antibacterial properties that kill microorganisms and inhibit their growth. The research team conducted a two-month follow-up test at the hospital, comparing the number of microorganisms in the curtain fabric treated with veneer tannins and the number of microorganisms in previous medical curtains, and found that tannin levels reduced the bacteria in the curtains by 60%, proving that resin and veneer tannins are practical antibacterial compounds.

Studies have found that slightly wetting the tannin coating can enhance its effectiveness and improve contact between bacteria and tannins. By comparing the tested areas and uncoated surfaces using several surface materials used in hospitals, the study confirmed the functionality and durability of wood tannins and resins that are stain-resistant and easy to clean. Hygiene measurements carried out by hospitals show that the level of hygiene in the coated area is 32% higher than that of the uncoated controlled surface.

In addition, the study involved testing ultraviolet camera technology, observing an increase in impurities on the surface using a UV-sensitive camera, and assessing the cleanliness of the coated surface. UV camera technology can identify stains on many different surfaces, and even visible impurities that cannot be seen under normal room lighting conditions are recognized by the technology. Tests were conducted on school building doorknobs, and photos of samples of doorknobs taken with ultraviolet cameras showed that even doorknobs that looked clean were accumulating pollutants, dirt and antimicrobial coatings that were deteriorating.

Studies that effectively demonstrate the availability of resins and wood tannins as antimicrobial coatings in hospital settings will further develop relevant materials and finished products to help hospitals use clean, harmless, and degradable coatings.
