An improved safety device for a self-contained breathing apparatus, and an improved self-contained breathing apparatus having thermal imaging capabilities.

A mask is provided that can inactivate viruses adhering thereto even in the presence of lipids and proteins regardless of whether or not the viruses have an envelope. The mask can inactivate viruses adhering thereto and includes a mask body provided with a member used when the mask is worn and virus inactivating fine particles having a virus inactivating ability and held by the mask body. The virus inactivating fine particles are particles of at least one selected from the group consisting of platinum(II) iodide, palladium(II) iodide, silver(I) iodide, copper(I) iodide, and copper(I) thiocyanate.

A compact aromatic diffuser configured to be used in conjunction with a breathing mask, allowing full consumption of the diffused essential oil by the user. The compact aromatic diffuser may also be used as a hand held inhaler for application proximate the user's face or a standalone diffuser for treating the atmosphere in a room or closed compartment.

A respiratory equipment for an aircraft, a pilot or first officer of the aircraft forming a user of the respiratory equipment, the respiratory equipment comprising a head armature, configured to be worn on the user's head, a respiratory mask configured to be applied, in a use position around the mouth and nose of a user, an inflatable harness configured to be coupled to a pressurized gas source, an inflation of the inflatable harness causing an extension of the inflatable harness such that the respiratory mask can be brought opposite the mouth and nose of a user, and a purge of the inflatable harness causing a constrained application of the inflatable harness against the mouth and nose of a user, wherein the head armature comprises at least an occipital member, and a front cradle for receiving and lodging the respiratory mask in a waiting position, wherein the inflatable harness is fixed to the occipital member and the inflatable harness is coupled to the respiratory mask.

A barrier system, device, and method protects medical professionals and patients from exposure to contaminants and bodily fluids. The system includes a head unit (e.g., 708) shaped to be worn over the head of the wearer; a hood (e.g., 704) positioned over the head unit; one or more sensors (e.g., 1902) configured to produce one or more sensor-output signals; and a controller (e.g., 1904) connected to the one or more sensors and configured to produce one or more controller-output signals based on the one or more sensor-output signals. Further, a device inside a barrier system is controlled by (a) sensing one or more characteristics; (b) producing one or more sensor signals based on the sensed one or more characteristics; (c) converting and/or processing the one or more sensor signals to produce one or more controller-output signals; and (d) controlling the device based on the one or more controller-output signals.

A breathing gas delivery system comprising a gas flow controller, at least one breathing apparatus, and at least one first length of tubing coupling the breathing apparatus to the gas flow controller. The gas flow controller has a body having an on/off switch, at least one gas input, at least one gas output, and at least one control mechanism for controlling flow of gas to the gas output. The breathing apparatus comprises a T-shaped gas input, a breathing bag coupled to the T-shaped gas input, a second length of tubing having two opposed ends, wherein one end is coupled to the other arm of the T-shaped gas input, a filter coupled the second length of tubing, and a nasal assembly coupled to the filter.

A device for regulating breathing gas delivered to a user, comprising a gas circuit comprising a main line having at least an upstream end intended to be connected to at least one gas source and a downstream end intended to be connected to at least one user station such as a mask, the main line comprising at least one electromechanical control valve configured to regulate the gas pressure between the upstream and the downstream, the circuit comprising a secondary line comprising an upstream end intended to be connected to at least one gas source and a downstream end intended to be connected to the same user station(s), the secondary line comprising at least one auxiliary member for regulating the gas flow, the device comprising a switching system configured to control the flow of gas between the upstream and the downstream of the circuit via the main line or via the secondary line, characterized in that the auxiliary member for regulating the secondary line is a pneumatic pressure regulator.

A firefighting or rescue apparatus includes a cab and a body having a storage unit configured to store a self-contained breathing apparatus, contaminated by harmful chemicals at an emergency scene, in the body rather than in the cab where occupants ride, so the occupants are not exposed to the harmful chemicals, which might be hazardous, toxic, carcinogenic or otherwise deleterious to health. The storage unit can include a storage wall mounted on upper and lower telescoping rail systems, and can be selectively movable relative to a compartment opening from a storage mode, where the storage wall is disposed in a compartment to a retrieval mode, where the storage wall extends beyond the opening so a user can access air tank supports to store a self-contained breathing apparatus. Related methods of storing a contaminated apparatus in the storage unit, distal from the cab and occupants thereof, are also provided.
