Protective mask that “starves” germs to death



目前,市面上的口罩主要针对PM2.5的防护设计,对颗粒物附着的大量病毒和细菌大多无能为力。我国专家新研发的一种生物防护过滤新材料,可有效截留病毒并通过生物技术将其“饿死”,达到“既阻隔又杀灭”的效果。由这种新材料制成的口罩不仅可以有效滤除PM2.5颗粒物,而且可以防病毒、防过敏原、防细菌。   这种口罩由北京汇朗生物科技研发。该公司研发团队主要由军事医学科学…

目前,市面上的口罩主要针对PM2.5的防护设计,对颗粒物附着的大量病毒和细菌大多无能为力。我国专家新研发的一种生物防护过滤新材料,可有效截留病毒并通过生物技术将其“饿死”,达到“既阻隔又杀灭”的效果。由这种新材料制成的口罩不仅可以有效滤除PM2.5颗粒物,而且可以防病毒、防过敏原、防细菌。

  这种口罩由北京汇朗生物科技研发。该公司研发团队主要由军事医学科学院、解放军总医院原科研人员组成。该团队围绕如何有效防护病毒所致的,特别是由呼吸道传播的疾病,如SARS,进行了深入研究和探讨。针对病毒所具有的共同特点,研制成功了对病毒、过敏原和细菌具有截留灭活作用的广谱生物防护过滤材料。试验显示,样品组病毒截留率-无纺布组病毒截留率的差值>40%,样品有截留效果。

According to the R&D personnel, this biological protection filter medium is mainly composed of a biological liquid that is harmless to the human body and a fiber layer sprayed with this liquid. This biological liquid is specifically combined with viruses, allergens, and bacteria and has high affinity. The receptors or ligands are scientifically formulated After natural air is filtered through this fiber layer, it can effectively adsorb and prevent viruses, allergens and bacteria from entering the human respiratory tract, and hinder the synthesis and metabolism of trapped viruses and bacteria. The intracellular lysosomal membranes of viruses and bacteria will rupture, autolysis and death �通俗来说,就是通过改变病毒和细菌赖以生存的微环境,将其“饿死”� �目前,“生物防护过滤介质及其应用”技术已获国家发明专利�
