SYSTEM AND METHOD FOR SELECTING A RESPIRATOR

摘要

Apparatus and associated methods may relate to a system for predicting a respirator fit by comparing a respirator model in a deformed state to a specific facial model. In an illustrative example, an internal measurement may be calculated between an inside part of the respirator model and the facial model. The internal measurement may be compared against a predetermined threshold to determine a fit of the respirator model, for example. In various implementations, the internal measurement may be a distance and/or a volume between the respirator and facial model. In some implementations, a 3D representation of the respirator model may be displayed upon a 3D representation of the facial model. In some implementations, a color-coded facial display may characterize areas of comfort and discomfort with respect to the respirator model. For example, areas of comfort and discomfort may be objectively determined in view of an applied pressure by the respirator.

1. A method of predictively fitting a respirator to a specific user, the method comprising:
retrieving respirator shape data representative of a shape of a selected respirator; capturing facial shape data representative of a facial shape of a selected facial area; overlaying said respirator shape data upon said facial shape data to obtain deformation parameters for said respirator; computationally deforming the respirator shape data according to the obtained deformation parameters; determining an internal dimension between an internal surface of said respirator and a portion of said facial area behind said respirator; and generating a fit recommendation for display to a user based upon said internal dimension between said respirator and said facial area.
