A modular breathing apparatus system integrating self-contained breathing apparatus (SCBA) and powered air purifying respirator (PAPR) capabilities in a unified platform includes a body-worn carrier frame with a removable air canister carrier configured to accommodate varying configurations of pressurized air canisters. A PAPR system with filter cartridges and blower removably attaches to the air canister carrier via a latching mechanism. A second stage regulator configured for connection to protective equipment selectively receives air from either the PAPR system or the SCBA system through an integrated shutoff mechanism. The modular design enables rapid reconfiguration between different air canister configurations without modifying other system components. The air canister carrier can be swapped to accommodate different sizes and numbers of pressurized air canisters while maintaining compatibility with the integrated PAPR system, addressing inefficiencies in traditional separate SCBA and PAPR systems and providing operational flexibility for varied mission requirements.

A portable air sterilization device attached to a respirator has been disclosed for personal protection of individuals working for long periods in highly infectious environments. This air sterilization device neutralizes 99.99% to 100% of aerosolized viruses and bacteria present in infected air and is portable. To sterilize infected air, the device uses a method of thermal stress (Grinshpun et al., 2010).

A mask frame, comprises a central conduit connection aperture and lateral arms having a 3-D curvature. The lateral arms extend: outwardly from a center of the frame, rearwardly, towards the patients ears, and upwardly, along a vector passing from below the nose to a point between the temple the top of the ear. The lateral arms "twist" along their length, such that a bottom margin of an end of each lateral arm is positioned further away from a notional vertical plane passing through the centre of the conduit connection aperture than a top margin. Also provided is an anti-rotation feature which limits or prevents rotation between straps of a headgear, and the mask frame. Further provided is a buckle for a closed loop headgear the buckle being formed with a plurality of openings and posts configured to form an angled headgear strap path through the buckle through which part of a headgear strap loop can pass. The buckle also comprises a friction loop opening through which a further of the headgear strap loop can pass, the angle of the angled path being such that the further part of the headgear strap loop frictionally engages the friction loop opening. 20 24 22 72 63 11 O ct 2 02 4 2 0 2 4 2 2 7 2 6 3 1 1 O c t 2 0 2 4
