Abstract: Face coverings that protect the facial T-Zone region (i.e., eyes, nose, and mouth) from airborne transmission of infectious and other harmful particles are disclosed. The face coverings disclosed herein are designed to attach to the temples, frames, and/or the bridge of eyewear, which provides protection for the eyes of the wearer and dispenses of the need to adjust straps traditionally found on face masks. The face coverings may be converted to different configurations depending on the amount of protection and comfort desired by the wearer. For example, the face coverings disclosed herein can convert from a free-hanging position to a more protective configuration in which the mask conforms closely to the face of the wearer.

Abstract: A vent arrangement is provided to a mask or associated conduit to discharge exhaled gas from the mask to atmosphere. The vent arrangement is structured to diffuse the exhaust vent flow to produce less air jetting, thereby increasing the comfort of the patient and their bed partner. For example, the vent arrangement may include one or more grill components and/or media constructed and arranged to diffuse vent flow.

Abstract: In an example, a ventilator includes an outer container containing liquid, an inverted container submerged in the liquid to provide inverted container space between a closed top and an inner container liquid level; gas supply line to supply breathing gas to the inverted container space; and inhalation line having an inlet in the inverted container space to provide breathing gas to patient. The inverted container moves upward from a first elevation when the inverted container space reaches a hydrostatic delivery pressure and volume of the inverted container space increases. The inverted container stops moving upward and the gas supply line stops supplying when the inverted container reaches a second elevation above the first. Based on a breath demand signal or preset timing, the inhalation line opens to permit flow of breathing gas to the patient at the hydrostatic delivery pressure, lowering the inverted container due to lost buoyancy resulting in sinkage.
