| Apparatus and associated methods may relate to a system for predicting a respirator fit by comparing a specific respirator model to a specific facial model in a dynamic position. In an illustrative example, one or more dynamic positions may be generated by actual user movement and/or simulated user movement. For example, a facial model may be generated by altering a static model in view of actual and/or simulated movements. In various implementations, a facial model may be compared against a variety of respirator models from a respirator model database. 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. | ||||||

| A quantitative fit test (QNFT) system and method for assessing the biological fit factor (FF) performance of respiratory protective devices. The biological QNFT system includes the following three main elements: an aerosol generation system; an exposure chamber; and an aerosol sampling subsystem. The aerosol sampling subsystem includes an aerosol spectrometer that counts particles in discrete size units ranging from 0.5 to 20 micrometers (μm) making it possible to obtain several size-specific FF measurements from a single respirator fit test. A virtual impactor in the aerosol generation system increases the number of challenge particles in the primary target size of interest (1 to 5 μm) and increases the sensitivity of the method allowing FF values of up to one million to be measured without the need to correct for in-mask background particles. | ||||||

The remaining service indication systems for respiratory protections systems provide a warning to the wearer that the capacity of the chemical sorbent to adsorb or absorb further compounds is nearly depleted. A remaining service life indication system has a computer memory device for storing information concerning the canister for determining an end of the service life of a gas mask, a canister and/or a cartridge and such devices from the input of various sensors. | ||||||
| 220 | RESPIRATOR FIT-TESTING APPARATUS AND METHOD | US13193410 | 2011-07-28 | US20110277759A1 | 2011-11-17 | Clifton D. Crutchfield |
| Improved respirator fit-test methods and apparatus featuring an automated, respirator wearer-controlled, air-leak measurement system. For fit testing of a respirator positioned on a test subject's face and connected to a controlled negative pressure testing apparatus, the test subject simply holds his breath and then activates a switch in electrical connection with said apparatus, which results in the automatic closure of the breathing port on the respirator and the initiation of a complete fit-testing protocol. The fit-testing apparatus includes a single, self-contained, automated unit that includes a vacuum source, an air-flow measuring device, and an air-pressure transducer for connection to a respirator being tested. By measuring the rate of air exhausted from the respirator in order to maintain a constant challenge pressure, an air leakage rate is determined. | ||||||
