Anesthesia mask adapter for alternatively sourced filter material

thingiverse

Hi Everyone, I'm excited to share this production-ready version of my design for converting anesthesia masks into improvised PPE. The part is attached to the mask using either Silicone or Epoxy, and then secured with a ~4" swatch of improvised filter material across the opening via a special clip. The clip's design allows for different thicknesses of materials without modification. So far, our top contenders for filter material are HEPA vacuum bags and HALYARD H600 sterilization wrap fabric, which may be plentiful in hospitals. I'd love to connect with someone who can provide guidance on testing these materials. Here's a video demonstrating how to attach a filter: https://youtu.be/7R3c6xa5Yk8 And here's a video showing how to glue the part onto a mask: https://youtu.be/nN5sEOZbJ_I This design can be adapted to other types of readily available masks if a suitable source is found. Must be printed in PET or ABS. All my prototypes have been printed in PET, as I believe PLA lacks the necessary flex for the fingers. I print my prototypes with 3 shells, solid infill, .6mm extrusion width, and .3mm layer height, achieving watertight prints on my machines. The adaptor can also be sealed with thinned epoxy or silicone.
