A portable chemical oxygen generator for delivering oxygen to a patient is described. The generator includes a housing containing a reaction chamber. Within the reaction chamber is a quantity of a peroxide adduct. A valve is provided with a lower portion of the valve in fluid communication with the reaction chamber. An upper portion of the valve is in fluid communication with a reservoir that holds a quantity of an aqueous solution. An internal chamber is formed within the valve by releasable seals that separate the internal chamber from the upper portion of the valve and a lower portion of the valve. The internal chamber holds a quantity of a peroxide-decomposing catalyst. The generator also includes a valve actuator. Operation of the valve actuator releases the seals in the valve and creates a fluid path from the reservoir through the internal chamber into the reaction chamber. When the valve is actuated, the aqueous solution flows from the reservoir through the internal chamber and into the reaction chamber. This flow washes the catalyst into the reaction chamber along with the aqueous solution. The solution and catalyst mix with the peroxide adduct and cause an oxygen-generating reaction.

A breathing mask includes a mask body unit and a container. The mask body unit includes a mask body having an inner surface configured to cooperate with a user's face to define an interior space therebetween, and two straps respectively connected to two opposite sides of the mask body. The container has a container body defining a chamber for receiving working liquid and formed with a plurality of vent holes for communicating the chamber with the interior space. At least one gas generating unit is connected to the container, and includes an electrolysis device disposed in a casing thereof for electrolyzing the working liquid into a hydrogen/oxygen gas mixture.

A method for inactivating medically important Gram-positive bacteria including Methicillin-resistant Staphylococcus aureus (MRSA), Coagulase-Negative Staphylococcus (CONS), Streptococcus, Enterococcus and Clostridium species, comprising exposure to visible light, and in particular light within the wavelength range 400-500 nm.

An oxygen generation apparatus of the first embodiment includes an outer container, a container lid, a piercing member, and an inner container. An annular flange is formed inside the inner container, and a surface of the annular flange is provided with two sealing films to accommodate an oxygen generating agent. The piercing member may move from a first position to a second position relative to the container lid, so as to break the sealing films to mix the oxygen generating agents to generate oxygen; an oxygen generation apparatus of the second embodiment includes two inner containers, where an annular flange is formed on one inner container to dispose a sealing film to accommodate an oxygen generating agent, a bottom surface of another inner container is provided in a concave manner with an accommodation space which accommodates the piercing member.

A portable oxygen generating system is provided that comprises a reaction chamber, a feed system for providing and controlling hydrogen peroxide solution to the reaction chamber, and a cooling/condensing system for cooling the hot oxygen and water vapor leaving the reactor and condensing and removing water. The portable chemical oxygen generation system produces humidified, breathable oxygen, that is substantially free of hydrogen peroxide and other contaminants, at a controlled flow and temperature over an extended period of time.

A sterilization, disinfection, sanitization, or decontamination system having a chamber defining a region, and a generator for creating a free radical effluent with reactive oxygen, nitrogen, and other species and/or a vaporizer. A closed loop circulating system without a free-radical destroyer is provided for supplying the mixture of free radicals from the generator mixed with the hydrogen peroxide solution in the form of the effluent to the chamber. The system is used in sterilizing, disinfecting, sanitizing, or decontaminating items in the chamber or room and, with a wound chamber, in treating wounds on a body. The wound chamber may be designed to maintain separation from wounds being treated. Various embodiments can control moisture to reduce or avoid unwanted condensation. Some embodiments can be incorporated into an appliance having a closed space, such as a washing machine. Some embodiments may include a residual coating device that deposits a bactericidal coating on sterilized items.

The invention relates to a device (1) for producing oxygen by means of a chemical reaction, in particular by means of an exothermic chemical reaction, wherein the device (1) comprises a chemical core (2), in which a substance producing oxygen by way of chemical reaction is present, and the chemical core (2) comprises a first reaction body (3) and a second reaction body (4) which are arranged in a manner such that they can be simultaneously activated, so that a first reaction front (13) propagates in the first reaction body (3) and simultaneously a second reaction front (14) propagates in the second reaction body (4).
