A carrier for carrying at least one compressed gas bottle of a breathing apparatus includes a carrier plate configured for removably receiving the at least one compressed gas bottle, and at least one filling element positioned in a space between the carrier plate and the at least one compressed air bottle. The at least one filling element includes a first positive connection element having a surface for engaging the at least one compressed gas bottle, and a second positive connection element connected to the first positive connection element and the carrier plate.

Proposed is an emergency evacuation oxygen mask provided with a hood configured to be worn on a user's head and an oxygen canister configured to supply oxygen to the user who wears the hood. The emergency evacuation oxygen mask includes an upper cover in which the hood is accommodated, a female coupling portion coupled to a lower end portion of the upper cover and connected to an oxygen supply port that is provided at the hood, and a male coupling portion provided on the oxygen canister and coupled to the female coupling portion, wherein when the upper cover or the oxygen canister is rotated, oxygen is discharged from the oxygen canister.

An air purifying mask having a face mask along with components some of which are arranged inside a casing. The casing may contain an air filtering system, along with other associated components for the mask including blower, appropriate pressure, flow control and filtration settings, and heating control. A flexible attachable/detachable connecting coaxial duct for inhale and exhale, may connect the mask and the air filtration system. The system may have a heating element for self-cleaning and temperature control. The heating element may also help for disinfection of air path within the system and air mask.

A cooling purified air breathing system for use during activity or in warm environments. The system includes a wearable portable air purifier having an opening for discharging cooling air, and a face mask configured to cover at least a user's nose and mouth. Air tubing is used to direct cooling filtered air into the mask, either through an opening or via a clip and connector attached to an edge of the mask. The air purifier is preferably worn in close proximity to the mask, such as around the back of the neck of the user.

Apparatus for supplying oxygen to a vehicle user, comprising a source of pressurized respiratory gas containing oxygen-enriched air, a flow-regulating and/or pressure-regulating unit, and at least one mask provided for supplying gas to the respiratory tract of said user, the regulating unit comprising at least one inlet connected to the source and at least one outlet connected to the mask, the regulating unit being configured to regulate the flow and/or the pressure of the respiratory gas supplied to the mask according to the respiratory demand of the user, the apparatus comprising at least one sensor measuring the pressure and/or the flow of respiratory gas delivered by the regulating unit to the mask, and an electronic data storage and processing unit configured to receive the measurements from the at least one sensor and to calculate, from these measurements, the frequency of the gas flows supplied to the mask and corresponding to the respiratory frequency of the user, to compare this calculated frequency against a threshold frequency and, when this calculated frequency is greater than the threshold frequency, to generate an audible and/or visual and/or vibratory warning signal.

A ducted breathing apparatus and methods for assembling and using such ducted breathing apparatus are provided. The ducted breathing apparatus may include a face cover for sealing at least a portion of a user's face. The ducted breathing apparatus may include a ducted air channel element for providing direct air flow from a user's mouth within the mask to the outside environment. The ducted breathing apparatus may include a coupling element for providing a sealed mating connection between the ducted air channel element and the face cover.

The invention relates to a respirator carrier frame 1 comprising a central frame portion 2, two wing portions 3 extending on opposing sides from the central frame portion 2, as well as at least one hinge 4 between the central frame portion 2 and each of the two opposing wing portions 3.

The present technology relates to open respirator devices having sensors for measuring breath biometrics. For example, a respirator device (100) can include a mask component (102) that fits at least partially over a user's face and forms a gap (112) between a periphery of the mask component and the user's face, thereby forming a breathing chamber (108) between the mask portion and the user's face. A fan unit can provide air from the external environment to the breathing chamber for the user to inhale. In some embodiments, the air may be filtered before entering the breathing chamber and the fans may provide a positive pressure seal between across the gap. One or more sensors can be coupled to the mask component for measuring one or more metrics associated with the user's breath.
