Development and Testing of a Low Friction and Biosuppressive, Fabric, Reusable Type II Medical Face Mask

随着对人员流动的限制被取消，可能仍有必要密切关注社交距离措施，包括戴口罩，以防止新冠肺炎从潜在感染者进一步传播给附近的其他人。因此，一次性医用口罩的使用可能会变得普遍。这些口罩在长时间佩戴后很可能会变得不舒服，而且处理数百万件此类物品可能会对环境产生巨大的负面影响。该项目旨在生产一种由织物制成的可清洗和可重复使用的口罩，符合现有一次性口罩的严格医疗和质量标准。这种面膜将有额外的好处，在衬里织物，已经用于其他医疗产品，以防止压力溃疡，将是非常舒适和干燥的皮肤。它将被设计为降低将包括新冠肺炎在内的病原体传播给他人的风险（通过防止呼吸、说话、咳嗽和打喷嚏时从口腔和鼻腔喷出的飞沫）。它将包含另一种创新的面料，这种面料具有天生的能力，可以在长达8小时的穿着时间内减少细菌的积聚。例如，根据英国政府的指导方针，在访问养老院、商店、理发店、健身房、电影院、体育赛事或任何公共场所时，都将建议穿着，因为这些地方有无法保持社交距离的风险。向公共机构（包括英国国民保健服务）和公众宣传，现在有一种舒适的、可重复使用的口罩，它已经通过了一次性口罩所需的所有功效测试。一种使用相同技术的不同形状的口罩将推出给普通公众，他们可能不愿意在日常生活中戴外科口罩。该项目还旨在使口罩达到某些NHS和其他医疗/兽医环境（IIR型）所需的最高保护水平。

As restrictions on movement of people are lifted it is likely that it will remain essential to pay careful attention to social distancing measures, including the wearing of masks to prevent the further spread of Covid-19 from potentially infected people to other people in close proximity. The use of disposable medical masks is likely to become widespread therefore. These masks may well become uncomfortable after longer periods of wear and the negative environmental effects of disposing of millions of such items could be substantial. This projects aims to produce a washable and reusable mask made of fabric that meets the strict medical and quality standards of the available disposable masks. This mask will have added benefits in the the lining fabric, already used in other medical products to prevent pressure ulcers, will be very comfortable and dry against the skin. It will be designed to reduce the risk of spreading pathogens, including Covid-19, to others (by preventing droplets from the mouth and nose being ejected by breathing, speaking, coughing and sneezing). It will contain another innovative fabric that has an innate ability to reduce the build-up of bacteria over periods with wear up to 8 hours. Wear will be suggested, for example, when visiting care homes, in shops, at hairdressers, in gyms, in cinemas, at sports events or in any public places where there is a risk of being unable to maintain social distancing, in accordance with UK Government Guidance.The extension for impact project will focus on alerting the companies, charities, public organisations (including the NHS) and the general public that a comfortable and reusable surgical-style mask is now available that has passed all of the efficacy tests required of the disposable equivalent. A different shape of mask using the same technology will be launched for members of the general public that may be reluctant to wear a surgeons mask in ordinary life. The project will also aim to take the mask to the highest level of protection required in some NHS and other medical/veterinary settings (Type IIR).
