摘要： An airflow control valve (20) for use in a breathing apparatus (10) to control a flow of air from a pressurized air supply to a respirator. The valve comprises an inlet port (31) for connection to a pressurized air supply, and first (32) and second (33) outlets. The valve is configurable between a first position in which the inlet port is in restricted fluid communication with the first outlet to allow a restricted flow of air from the inlet port to the first outlet and in which the second outlet is sealed from the inlet port and, a second position in which the inlet port is in substantially unrestricted fluid communication with the second outlet to allow an unrestricted flow of air from the inlet port to the second outlet.

摘要： Apparatus and associated methods relate to fitting a virtual mask to a virtual face by first fitting a chin region of the virtual mask to the virtual face, then determining an virtual mask angle that maintains the fitted chin region while simultaneously fitting a nose-bridge region of the virtual mask to the virtual face, and then calculating a fit-quality metric corresponding to the fitted position. In an illustrative embodiment, the fitted chin region may include the high curvature menton region of the chin. In some examples, a virtual mask may be virtually pressed toward the virtual face using a predetermined force corresponding to a force of a mask securing device of a real mask corresponding to the virtual mask In an exemplary embodiment, the fitting of a virtual mask to a virtual face may advantageously yield a mask's fit quality in a brief amount of time.

摘要： An air delivery hose (10) has a CBRN resistant outer butyl rubber layer (12) convolute over a metal wire reinforced thermoplastic polyurethane inner hose (14). A combination unit respirator (20) has an air delivery hose (10, 10′) with a proximal end (22) with a three position lockable switch (40) that allows selection of APR, PAPR or SCBA modes, and a distal end (24) with a compact demand valve (30) responsive to the switch position. A filter cover accessory (60) is a modular accessory to a PAPR manifold that protects a PAPR filter (62) from premature degradation in harsh environments.

摘要： Apparatus and associated methods relate to determining a fit-quality metric for a mask/face combination based upon a calculated dead-space volume between a virtual mask and a virtual face virtually aligned so as to create an integrity seal circumscribing a mouth and nose region. In an illustrative embodiment, an interactive virtual fitting system may receive a three-dimensional (3D) virtual face associated with a person. The system may retrieve 3D models of various respirators selected by user determined criteria. The system may then compute a fit-quality metric for each of the retrieved 3D models. The potential wearer may then be presented with the metrics for review. The potential wearer may select a respirator based upon these computed metrics. A virtual fitting of many respirators may advantageously reduce the time needed for selecting a properly fitting respirator while simultaneously ensuring that the selected respirator may be comfortable and well fitting.

摘要： An emergency oxygen supply system for use on aircraft in the event of a loss in cabin pressure is configured for delivering allotments of oxygen and timing the delivery such allotments to each passenger so as maximize the efficiency of the transfer of such oxygen into the passenger's bloodstream. The delivery of each allotment is selected so that the entire allotment is available for inhalation into the region of the lung most efficient at oxygen transfer while the volume of the allotment is selected to substantially coincide with the volume of such region of the lung.
