    摘要: An exhale valve assembly includes a housing, a valve carrier body, a primary valve assembly, a plunger, a lock assembly, and an air pressure activated actuator assembly. The valve carrier body is disposed the housing and has a passageway. The primary valve assembly is mounted to the valve carrier body. A first air flow path passes through the passageway and a second air flow path passes through the primary valve assembly. The plunger is configured to permit a flow through the first air flow path when the plunger is in a first position and to direct a flow through the second air flow path when the plunger is in a second position. The lock assembly is configured to secure the plunger in the first position. The air pressure activated actuator assembly is configured to release the lock responsive to a pressure change within the cavity of the housing.

    摘要: A configurable exhale system for a respirator has a first valve assembly disposed within a chamber which is configured to prevent air from flowing through the first valve assembly when an air pressure differential between an upstream side and a downstream side of the first valve assembly is below a first opening pressure. A second valve assembly is disposed within the chamber in fluid communication with the first valve assembly which is configured to prevent air from flowing through the second valve assembly when an air pressure differential between an upstream side and a downstream side of the second valve assembly is below a second opening pressure, which is greater than the first opening pressure. A bypass opening is positioned adjacent the second valve assembly configured to enable air to bypass the second valve assembly with a bypass member positioned adjacent to the bypass opening. The bypass member is movable between two positions with the bypass member blocking the bypass opening in a first position and the bypass member does not block the bypass opening in a second position.

    摘要: A respiratory inlet having a mask end and a fitting end is provided. The respiratory inlet also includes a cavity and an exterior mating surface. The exterior mating surface is disposed proximate the fitting end, and is configured to matingly accept a first type of air supply fitting. The first type of air supply fitting is configured as a female fitting, and the respiratory inlet is configured to operate in a first mode when the female fitting is mated to the exterior mating surface. The cavity includes an opening oriented toward the fitting end, and an interior mating surface configured to matingly accept a second type of air supply fitting. The second type of air supply fitting is configured as a male fitting, and the respiratory inlet is configured to operate in a second mode when the male fitting is mated to the interior mating surface.
