22mm Draining Valve cover Adapter for EasyBreath Decathlon Mask

grabcad

As already done by oceanreef for its masks, this adapter makes it possible to mount 22mm filters for medical use on the draining valve of the decathlon easybreath mask. The design was intended to be sealed with silicone to the body of the mask in order to guarantee a secure seal since there is no seal element. By sealing the adapter with silicone, you can remove the drain valve (also known as chin valve). We advise using these masks transformed into PPE only in extreme circumstances. There are differing opinions on the use and effectiveness of these devices as PPE. Therefore, I am providing below links to two of several publications available on this matter. https://docs.google.com/document/d/1J22le3dBZBnNDXGlJLRb38z7v7LaOjKfDeN9f0tFeKY/edit#heading=h.kbdc4jqikxwz https://antwerpdesignfactory.be/decathlon.html?fbclid=IwAR2wIJQrCjazJ26KXFARSE2e4llA21Qjkuc_kfzt-6JTRq-T1ooBejwC-bk#Methods Print the top at high resolution, using flexible materials (avoid ABS or non FDA compliant).
