Materials such as polyvinyl chloride, polypropylene, and polyethylene are used for the construction of medical equipment, including inhalation equipment. Inhalation equipment, because of the wet conditions and good oxygenation, constitutes a perfect environment for microbial biofilm formation. Biofilms may affect microbiological cleanliness of inhalation facilities and installations and promote the development of pathogenic bacteria. Microbial biofilms can form even in saline environments. Therefore, the aim of this study was to evaluate the effect of medicinal brines on microbial biofilm formation on the surfaces of inhalation equipment. The study confirmed the high risk of biofilm formation on surfaces used in inhalation equipment. Isolated microorganisms belonged to potential pathogens of the respiratory system, which can pose a health threat to hospital patients. The introduction of additional contaminants increased the amount of bacterial biofilm. On the other hand, the presence of brines significantly limited the amount of biofilm, thus eliminating the risk of infections.
材料如聚氯乙烯、聚丙烯和聚乙烯被用于医疗设备的构建，包括呼吸设备。呼吸设备，由于湿润的条件和良好的氧合作用，构成了微生物生物膜形成的完美环境。生物膜可能会影响呼吸设备和设施的微生物清洁度，并促进病原菌的发展。微生物生物膜甚至可以在盐环境中形成。因此，本研究的目的是评估药用盐水对呼吸设备表面微生物生物膜形成的影响。研究证实了在呼吸设备表面形成生物膜的高风险。分离出的微生物属于呼吸道的潜在病原体，可能对医院患者的健康构成威胁。引入额外的污染物会增加细菌生物膜的数量。另一方面，盐水的存在显著限制了生物膜的数量，从而消除了感染的风险。
