Stopgap Surgical Face Mask (SFM)

This model has been superseded by Stopgap Surgical Face Mask revision B, which was designed to increase comfort.  This version may still be used, but see the revision B link for improvements.

This item should only be manufactured in a current Good Manufacturing Practices (cGMP) facility. If this is not manufactured in a cGMP facility under an appropriate quality management system, it should not be used in a clinical setting. 

This mask should only be printed with Multi-Jet Fusion (MJF) or Selective Laser Scintering (SLS) technologies out of powder-bed nylon

The Stopgap Face Mask was created as an emergency action in effort to protect people by providing backup PPE options if the standard PPE has become unavailable. This device has not gone through the same regulatory approval process as standard PPE.

The Stopgap Face Mask consists of two main components (the mask body and the filter cover) and contains features for attaching two elastic straps and receiving a patch of filter material.  It is recommended that the rectangular filter patch and elastic straps are disposed of after every use of this device. The remaining parts of the plastic mask can be disinfected using common disinfecting solutions or sterilized and reused.
