Cost Effective Disposable Face and Eye Protection for Medical Professionals

在最近的新冠肺炎大流行之后，对医疗领域的许多工作人员使用脸部/眼睛保护的要求有所增加。现有的产品在几何结构上很简单，这损害了它们保护用户的有效性，并且没有提供清晰的愿景。它们长时间佩戴也不舒服，而且价格昂贵，因为它们不是为一次性使用而设计的。设计意图是用最少的部件以低成本生产一种一次性口罩。它在使用者的眼前提供了一个高清晰度、无失真的区域，同时还显著地包裹了面部，提供了最大限度地防止空气污染物的保护。防护罩是真空成型的，两边都涂上了防雾涂层。防护罩磨损后，用可调节的注塑带子固定在适当的位置，将使用者的头部包裹在耳朵以上。盾牌将作为一个完整的组件或一套4个部件提供，并由第一个操作员组装，以将供应成本保持在最低限度。一旦调整好，盾牌就可以像戴上正确尺寸的帽子一样轻松地拆卸和更换。这款背带是为舒适而设计的，可以容纳所有成人的头部尺寸。所有用于此的材料都是100%可回收的。

Following the recent COVID-19 pandemic there has been an increased requirement for the use of face/eye protection for many workers in the medical field. Existing products are simple in their geometry which compromises their effectiveness in protecting the user and does not provide clear vision. They are also uncomfortable to wear over long periods and expensive as they have not been designed for single use.The design intent is to produce a disposable face mask to be produced from the least number of parts and at low cost. It provides a high clarity distortion-free region in front of the users' eyes yet a significant wrap-around of the face to provide the maximum protection from airborne contaminants. The Shield is vacuum formed with an anti-fog coating applied to both sides.The Shield is worn and kept in place with an adjustable injection moulded strap which surrounds the users' head above ear level. The Shield would be supplied as a complete assembly or as a set of 4 parts and assembled by the first operator to keep supply costs to a minimum.Once adjusted the Shield could be removed and replaced as easily as wearing a cap of the correct size. The strap has been designed for comfort and would be ranged to accommodate all adult head sizes.All materials used for this are 100% recyclable.
