| 63 | INDICATING HAZARDOUS EXPOSURE IN A SUPPLIED AIR RESPIRATOR SYSTEM | US15190564 | 2016-06-23 | US20170368381A1 | 2017-12-28 | Steven T. Awiszus; Kiran S. Kanukurthy |
| An exposure-indicating supplied air respirator system comprises a head top, a clean air supply source and a portable personal communication hub. The head top comprises a visor that is sized to fit over at least a user's nose and mouth, a position sensor secured to the head top, and a head top communication module. The clean air supply source is connected to the head top that supplies clean air to the interior of the head top. The position sensor detects whether the visor is in a closed position or in an open position and the head top communication module communicates the visor position to the personal communication hub.

| 64 | Device for Fit Testing of Gas Masks | US15593503 | 2017-05-12 | US20170326311A1 | 2017-11-16 | Bryan I. Truex; Gueorgui M. Mihaylov; Ryan Day |
| Fit testing is conduct to ensure that gas mask provide proper protection to workers that may be exposed to airborne contamination. Standard fit test procedures require the mixing of fit test compounds to specific fit testing composition required for threshold testing and subsequent fit testing. A device is needed for easy mixing of the components of the fit test composition and easy delivery of fit test composition during a fit test. For example, a device for fit testing of a gas mask on an individual wearer may include a sprayer, at least one ampoule containing a fit testing component, and a reservoir containing the ampoule and a solvent for the fit test component. The reservoir may be hollow body having a sealed inner volume. The reservoir may be deformable to break at least one hermetically sealed ampoule without tearing or otherwise breaking the reservoir. Therefore, the ampoule may be broken within the reservoir to mix the gas mask fit testing component into the solvent to generate the desired concentration for either a threshold test or gas mask fit test. | ||||||

| Indicating fit status of a mask in communication with a respiratory assistance device is disclosed. Upon initiating a therapeutic gas delivery from the respiratory assistance device to the mask, one or more measurements from respective one or more sensors of the respiratory assistance device is received. A leakage value from these measurements is derived, and a mask fit index is assigned. This is based at least upon a correlation of the leakage value to a particular sub-range of predetermined leakage values that corresponds to the mask fit index. The particular sub-range of predetermined leakage values is one among a plurality of sub-ranges, which together comprises an overall mask fit range defined at least by an ideal mask fit region, a loose mask fit region, and a tight mask fit region. A mask fit status based upon the assigned mask fit index is output to an indicator interface. | ||||||

| 76 | Respirator fit-testing apparatus and method | US13193410 | 2011-07-28 | US08528559B2 | 2013-09-10 | 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. | ||||||

| A sealing device for positive pressure testing is attached to a respirator face mask and includes an outer frame integrally joined to a movable cap by a flexible link that biases the cap in an open position for the operational use of the face mask against a manually applied force to move the cap to a sealed position for the positive pressure testing to assure the proper fit of the face mask on the wearer. The method for positive pressure testing includes flexibly moving the sealing device from the open position to the sealing position such that the sealing surface of the cap seals the exhalation valve assembly closed. The wearer then exhales into the mask to test the seal of the mask. When the test is completed, the sealing device is released and the inherent biasing force moves the cap from the sealing position to the open position. | ||||||
