Abstract: A powered air purifying respirator includes an inlet air filter; a flow generator configured to cause air from an ambient environment to flow through the inlet air filter and elevate pressure of the air to above ambient conditions; a mask in fluid communication with the flow generator and configured to fit tightly against a user's face or neck for delivery of the air to the user at the elevated pressure; and a one-way outlet valve configured to allow air exhaled by the user to be vented to the ambient environment. An outlet filter may be included to filter the air flowing through the one-way valve, and the outlet filter may be retrofit. The outlet filter may be preferred when filtration of both inlet and outlet air is desirable.

Abstract: A method includes detecting an event at a wearable mobile device, generating an alert in response to the event, and transmitting the alert over a communication path that comprises a cellular network. The wearable mobile device, such as a watch, necklace, bracelet, and the like, includes a safety module/application. The safety module/application may incorporate both event detection via one or more sensing or recordation modules and notification functionality. Emergency contacts, including public safety organizations, family members, friends, and the like may be notified in a variety of ways based on the particular event that is detected.

Abstract: A CPAP device includes a humidifier including humidifier tub having a heat conducting base plate; and a cradle to support the humidifier tub in an operative position. The cradle may also support a flow generator in operative relation to the humidifier tub. The cradle includes a heater plate in communication with the heat conducting base plate of the humidifier tub in use. The cradle further includes a retaining mechanism to retain the humidifier tub in the cradle, the retaining mechanism being structured to force the base plate into engagement with the heater plate. The humidifier and/or flow generator may include various features to manage inadvertent back-spill of water from the humidifier to the flow generator.

Abstract: A CPAP device includes a flow generator including an outlet, a humidifier including an inlet, and an adaptor connector between the outlet of the flow generator and the inlet of the humidifier. The connector includes a flexible and conformable sealing portion that is movable to accommodate misalignment.

Abstract: A mask system includes a frame, cushion, cushion clip, swivel elbow, headgear and/or headgear clips that are configured for use in a clinical or hospital environment. One or more components of the mask system are configured to promote single patient use, e.g., by providing an age indicator and/or preventing disassembly and/or cleaning, etc.

Abstract: A medicament container configured to improve entrainment of the medicament in the air and to improve deposition of the medicament in the lungs includes an upper layer and a bottom layer with medicament disposed therebetween. The upper layer is punctured to provide first and second openings to allow airflow to enter and exit through the upper layer of the medicament container. In a preferred embodiment, the medicament container has a projection which forms an elbow-shaped medicament containment/flow channel between the upper layer and the lower layer. The medicament container is preferably used in a housing which selectively controls airflow through the medicament container and the housing to improve deep lung deposition of the medicament.
