Rawwater 'click-fit' reusable visor for pandemic protection/humanitarian aid

**考虑到当地全科医生、一线医护人员、关键工作人员和护理人员在抗击COVID-19时无法获得全脸保护的人数，总部位于沃灵顿的Rawwater Engineering Company Ltd.着手设计一种可重复使用的面罩。Rawwater只用了不到三天的时间就完成了原型设计，并开始为医护人员免费3D打印护目镜。与传统的一次性遮阳板不同，它使用透明的醋酸片，用于一次性使用，Rawwater的遮阳板使用坚固的国内，餐饮或医疗质量的一次性保鲜膜。使用后，保鲜膜很容易取出并折叠起来，作为医疗废物安全处理。然而，遮阳板可以重复使用，并在第一次用米尔顿或类似消毒后重新涂膜。这意味着，在大流行期间或其他有感染传播风险的情况下，只需要一个遮阳帽和一套廉价的薄膜就可以帮助医务工作者/关键工作人员保持安全。与醋酸盐供不应求不同，合适等级的保鲜膜很容易获得。Rawwater遮阳板具有简单的点击设计和一种巧妙而直接的方式来拉伸遮阳板膜，以确保它保持教导和清晰。遮阳板重量轻，舒适，可以戴在处方眼镜。它不会起雾或影响佩戴者的视力。Rawwater一直在用两台3D打印机尽可能快地打印遮阳板。为了加速生产，它还允许其他企业免费使用其设计。也就是说，Rawwater只需要24小时就能打印出4个遮阳板。这是一段很长的时间。进一步发展的设计，快速，高效的注射成型是答案。Rawwater认为它的遮阳板设计提供了一个有效的解决方案，无论传统的面部保护是迫切需要/短缺。该公司将利用Innovate UK授予的资金：•进一步开发遮阳板设计，以实现快速、经济高效的规模扩展；•研究专门用于遮阳板的一次性薄膜；•确保所有必要的监管批准；•与精心挑选的专家合作，开始为医院、医疗保健/关键工作人员、海外和人道主义援助开发紧急遮阳板/薄膜包——事实上，在任何情况下，可重复使用的遮阳板都可能是生与死的区别。该项目将在Rawwater的研究中心创造至少5个技术岗位。

**Reusable visor to protect healthcare staff from COVID-19**Concerned by the number of local GPs, frontline healthcare staff, key workers and carers who were unable to obtain full-face protection in their fight against COVID-19, Warrington-based Rawwater Engineering Company Ltd. set about designing a reusable visor.It took fewer than three days for Rawwater to finalise its proto type design and begin 3D printing visors free of charge for healthcare staff.Unlike traditional disposable visors which use clear acetate sheet and are intended for single use, Rawwater's visor uses strong domestic, catering or medical-quality disposable cling film.After use, the cling film is easily removed and folded in on itself for safe disposal as medical waste. The visor, however, can be reused and re-filmed after first being sterilised with Milton or similar.This means that just one visor and a supply of inexpensive film could help keep a medical worker/key worker safe for the duration of a pandemic or in other circumstances where there is a risk of infection transmission.Unlike acetate that is in short supply, suitable grades of cling film are readily available.The Rawwater visor features a simple click-together design and an ingenious yet straightforward way of tensioning the visor film to ensure it remains taught and clear.The visor is lightweight, comfortable and can be worn over prescription glasses. It does not mist up or impact the vision of the wearer.Rawwater has been printing visors as quickly as it can using two 3D printers. To accelerate production, it has also given other businesses free access to its design.That said, it takes Rawwater 24 hours to print just four visors. And that's a long time. Further development of the design for fast, efficient injection moulding is the answer.Rawwater sees its visor design as providing an effective solution wherever traditional face protection is in urgent need/short supply.The company will use the funds awarded by Innovate UK to:• Further develop the visor design for rapid, cost-effective scale-up,• Research disposable films specifically for use with the visor,• Secure all necessary regulatory approvals,• Work with carefully selected specialists to begin developing emergency visor/film packs for hospitals, healthcare/key workers, overseas and humanitarian aid - in fact, any circumstances where a reusable visor could be the difference between life and death.The project will create at least 5 skilled jobs at Rawwater's research centre.
