Healthcare Protective Air Filtration

传统的一次性外科口罩或FFP 2或FFP 3口罩在危急护理情况下的使用，例如在治疗新冠肺炎患者时所需的使用，在使用和有效保护使用者方面存在缺点。一次性口罩的正确佩戴是一个主要问题，测试表明，这些类型的口罩的效率可以降低30%以上，由于面部毛发或不同脸型周围的不合适。佩戴这些面罩会产生呼吸阻力，并且面罩内的热量和水分会积聚，使得佩戴这些面罩特别是长时间佩戴时不舒服和不愉快。事实上，在关键的COVID-19护理情况下工作的医生的反馈在电视采访中得到了强调，他们发现很难工作超过2小时。戴这种类型的口罩突出的另一个问题使医生和护士难以有效沟通，一些报道诉诸于使用对讲机来帮助沟通。由于无法完全看到面部，因此很难识别重症监护人员（因此需要在PP工作服上写上姓名和工作职能）我们提出的保护性空气过滤系统使用引导的空气流在面部上形成保护屏障，防止有害污染物颗粒的呼吸，从而提供比典型空气过滤系统更高的保护系数。FFP 2和FFP 3口罩。空气滤网（在透明面罩后面产生）不会覆盖面部，因此它是完全可见的，不会妨碍言语交流，也不会隐藏面部，使护理专业人员之间的互动更加流畅和自然。它的主要好处是不会因热量和水分积聚而引起不适，但实际上会产生一股清新的气流供用户呼吸，保持用户凉爽和平静。GEO ltd使用行业标准向内泄漏测试协议进行了模拟和物理测试，以验证他们开发和拥有的气流技术结果证实性能等于或优于最佳性能的一次性口罩，并且结果不会由于头发的面部形状而降低性能。GEO需要资金将该技术开发成可行的商业产品。GEO是一家工业设计顾问公司，曾为客户成功设计和开发了许多呼吸系统，为客户提供商业PAPR和SCBA套件。在新冠肺炎大流行期间，市场开放，为医疗保健以外的PPE需求提供了广泛的扩展。现在，在许多部门，包括教育、酒店、零售、工业和办公室环境中，安全地开展活动都需要有效的PPE。这不仅增加了HPAF的市场潜力，还需要更多样化的产品供应和业务战略来成功瞄准这些市场。

The use of conventional disposable surgical masks or FFP2 or FFP3 masks in critical care situations such as needed when treating covid-19 patients have disadvantages in use and in protecting users effectively.Correct fitting of disposable masks is a major issue, tests have shown efficiency of these types of masks can be reduced by over 30% due to facial hair or bad fitting around different face shapes.Wearing of these masks create breathing resistance and the build up of heat and moisture within the mask making them uncomfortable and unpleasant to wear particularly over extended periods of time. Indeed feedback from doctors has been highlighted on TV interviews working in critical covid -19 care situations where they have found it difficult to work for longer than 2 hours.Another issue highlighted by wearing these types of masks has made it difficult for doctors and nurses to communicate effectively, some reporting resorting to using walkie talkie radios to aid communication. Not being able to fully see the face makes recognition of the critical care worker difficult (hence the need to write the name and job function on PP gowns) and impossible to interpret facial expression and effective verbal communication.The protective air filtration system we are proposing uses guided air flows over the face to create a protective barrier from respiration of harmful contaminant particles providing increased protection factor over typical FFP2 and FFP3 masks. The air screen (generated behind a clear face guard) does not cover the face so it is fully visible, does not impede verbal communication and does not hide the face from view making interaction between care professionals much more fluid and natural.And the major benefit it does not cause discomfort from heat and moisture build up, but in fact creates a refreshing stream of air to breath keeping the user cool and calm.GEO ltd have simulated and physically tested using industry standard inward leakage test protocols to validate the air stream technology they have developed and have had results confirming performance equal to or better than best performing disposable masks and results which do not degrade performance due to facial shape of hair.GEO require funding to develop this technology into a viable commercial product. GEO are industrial design consultants that have worked on the successful design and development of many respiratory systems for clients delivering commercial PAPR and SCBA kit.During the progression of the covid pandemic the market has opened up to provide a vast extension to PPE requirement outside of healthcare. Effective PPE is now required in conducting activities safely in many sectors including education, hospitality, retail, industrial and office environments. This not only increases the market potential for HPAF but also requires a more diverse product offering and business strategy to successfully target these markets.
