| titleOfInvention |
Face mask seal for use with respirator devices and surgical facemasks, having an anatomically defined geometry conforming to critical fit zones of human facial anatomy, and capable of being actively custom fitted to the user's face |
| abstract |
The present disclosure is a face seal (FS) device for filtering face piece respirators (FFR) of all types, that corrects inner face seal leakage (FSIL) of particulate material that occurs due to well documented failures in FS designs of the prior art. The present disclosure differs from those of the prior art in having compensatory accentuations at locations along the entire 360 deg. FS inner perimeter that are based on specific details of facial human anatomy which are known to be sites of FSIL. The FS is also constructed of a heat activated thermoplastic copolymer that enables the device to be custom fitted to the user's face. Experimental data, confirmed with workplace protective factor (WPF) studies, show a 60-240 fold improved performance over FS designs of the prior art. |
