CV-19 Guardian Respirator Adaptor · 模型 199208
In response to shortages in NIOSH-approved PPE during the COVID-19 crisis, many individuals including healthcare professionals and first responders are turning to improvised masks for protection. To help provide for more controlled protection under these circumstances, Dominion Engineering, Inc. (DEI) has developed a custom adaptor that, along with commonly available materials, can be used to convert a standard snorkel mask into a reusable, full face respirator that effectively protects the eyes, nose and mouth from airborne particles. We have coordinated independent testing to confirm that these converted masks pass a standard mask fit test and to assess the efficacy of commonly available filter insert materials. To assist individuals who may lack access to approved PPE such as N95 respirators and face shields, DEI is publishing the CV-19 Guardian Respirator Adaptor design here, along with instructions for making a converted mask using this adaptor. For additional technical information, including filter efficacy testing results for commonly available materials that can be used to make filter inserts for this adaptor, refer to the attached PDF file. Disclaimer: Improvised devices of the type discussed herein are not NIOSH-approved and the user bears all liability associated with the use of such devices. DEI is making this information available as a public service, but does not make any warranty, expressed or implied, that the use of the device described herein will protect a party from COVID-19 or any other airborne viruses. To assemble a converted respirator mask, you will need the following: 1 - 3D printed adaptor (design file attached) 2 - Compatible snorkel mask 3 - Filter insert material 4 - Wide mouth lid (mason jar, or equivalent) Snorkel Mask: The CV-19 Guardian Respiratory Adaptor is designed to fit the DIVELUX snorkel mask (https://www.amazon.com/dp/B072KDWVSV/ref=cm_sw_em_r_mt_dp_U_PJ5FEbJPZE8VG). Many other commonly available snorkel masks utilize similar construction. DEI will continue to evaluate the compatibility of other masks with the CV-19 Guardian Respirator Adaptor and publish additional compatibility information as it becomes available. Filter Insert: Once the CV-19 Guardian Respirator Adaptor is inserted into the compatible snorkel mask, a filter insert cut from a commonly available material that effectively captures airborne particles is placed on the sealing surface of the adaptor and secured in place using a compat...
