Abrégé

A modular powered air purifying respirator (PAPR) is provided including one or more of a first inlet configured to receive an ambient gas, a gas filter in fluid communication with the first inlet and configured to filter the ambient gas; a blower configured to boost at least one of a flow rate or a pressure of the ambient gas entering and/or exiting the gas filter; a second and independent inlet configured to receive a non-ambient gas; a first outlet configured to selectively provide a breathing gas to a user from the ambient gas or the non-ambient gas; and/or a controller and switching device configured to select the source of the breathing gas between the first inlet and the second inlet. Embodiments may also include a power source for the blower.

A filter housing for use with a protective mask or other personal protective equipment is described including a base, a top, a sidewall connecting the top and the base, and a void that houses a filter medium or a filter medium cannister. The housing also includes an inlet with an inlet opening for receiving ambient gas into the container, an outlet including an outlet opening for discharging gas from the container to the protective mask, and an interface for removably securing the filter housing to the protective mask or other personal protective equipment. The base may include a concave surface substantially surrounding the opening and the interface, and a space between the void and the concave surface of the base may be partitioned by a plurality of members connected at least partially to the base or the sidewall and define a substantially planar surface facing the void.

The present invention relates to a breath controlled air inlet valve for controlling a flow of air supplied to a wearer of a facemask, the valve permitting the flow of air when a wearer breathes in and restricting the flow of air when the wearer breathes out. The valve includes an inlet, an outlet, one or more pivotable shutters, and a shutter articulating mechanism for articulating the one or more shutters between an open state and a closed state. The shutter articulation mechanism actuates in response to the respiration of the wearer. The valve also enables a positive pressure to be maintained within the facemask by permitting an amount of air to flow around the one or more shutters when the one or more shutters are in the closed state.

A collapsible patient isolation pod for preventing flow of contaminants to or from a patient is disclosed. The isolation pod is preferably fabricated at least partially from a transparent, biochemically resistive material and includes a flexible enclosure that is configurable to receive a contaminated patient therein. The top is maintained spaced apart from the bottom such that the top is maintained out of physical contact with a contaminated patient received in the enclosure. The isolation pod has a plurality of wide, gloved access points to allow easy, multiple access points to a patient. A central connection manifold for oxygen, intravenous connections, or other fluids, may optionally be provided. Ventilation is provided within the isolation chamber with a negative pressure ventilation system and filtration on the air input near the patient's head, and provides filtration on output near the patient's feet. An integral pocket underneath the isolation pod may be provided to allow for a spine board or stretcher to be used. The invention provides a patient isolation system that permits health care providers safe and relatively unencumbered access to the isolated patient.
