A cartridge system comprising a container and at least four cartridges for generating oxygen, a compressor for compressing the generated oxygen, at least one storage tank configured to store the compressed oxygen received from the compressor, an oxygen pressure regulator enabling a uniform flow of oxygen at pre-defined oxygen pressure, an oxygen flow control knob regulating flow ratio of the oxygen being supplied to the patient in an instant, a humidifier means imparting humidity to the oxygen being supplied to a patient, and a display unit displaying a set of information associated with the system and communicatively coupled to the portable oxygen generator system 10 via wireless network. The cartridges may be triggered in a plurality of ways to maintain a continuous outflow of generated oxygen for a longer duration. Further, the operation of the system may be monitored or controlled wirelessly from a distant location.

An apparatus for delivering pressurized, humidified breathable gas to a patient having a sleep-related disorder includes a CPAP unit with a blower configured to generate a flow of pressurized breathable gas. The Apparatus also includes a liquid storage container configured to hold a body of liquid. The liquid storage container has a gas feed opening, a gas discharge opening and a humidifying region above a metallic heat conducting material. In addition, the apparatus includes a support housing integrated directly into the CPAP unit and having a receiving space configured to removably receive the liquid storage container. The liquid storage container is structured such that when the liquid storage container is received by the support housing, the gas feed opening aligns with and engages with an ending portion of a gas feed flow path defined by the support structure and the gas discharge opening aligns with and engages with a beginning portion of a gas discharge flow path defined by the support structure so that the liquid storage container fluidly connects the gas feed flow path and the gas discharge flow path.

A system includes a closed-circuit respirator (1) with a breathing mask (2), a closed breathing circuit, which leads from the breathing mask via an exhalation tube (3), a lime cartridge (4) for binding CO.sub.2, a spring-loaded breathing bag (5) and an inhalation tube (7) to the breathing mask. A pressurized oxygen tank (11) is connected to the circuit via a constant dispensing unit (8) and to the breathing bag via a minimum flow control valve (9), which opens upon a collapse of the breathing bag (lack of breathing gas in the circuit) and fills the breathing bag from the oxygen tank. A pressure sensor (12) detects the pressure in the oxygen tank. A constant dispensing unit introduces oxygen with a volume lower than a mean oxygen volume demand. A monitoring device (13-15) calculates a quantity of oxygen consumed and still remaining from the detected pressure and an initial pressure value.

An air purifier. A dry filter section includes a filter member, a dust sensor, and a UV lamp to primarily collect ultrafine dust particles. A suction pump is disposed to forcibly supply the intaken air with the dust particles removed. First and second wet purification sections are filled with water to secondarily purify the intaken air and purified air. A control section controls the operation of the suction pump and respective valves connecting the dry filter section, and the first and second wet purification sections. First and second bubble removers are rotatably provided in the first and second wet purification sections, respectively, to remove air-bubbles injected into the first and second wet purification sections, under the control of the control section.

A positive pressure gas supply system configured to supply positive pressure gas to a patient includes a CPAP unit configured to generate a flow of positive pressure gas. A humidifier base is positioned to receive the flow of positive pressure gas from the CPAP unit. A receiving portion of the humidifier base is configured to removably receive a refilling module. The refilling module is configured to hold a volume of water, complete a gas flow path partially defined by the humidifier base, and humidify the positive pressure gas. In addition, a respiration tube connecting portion is positioned to remain in communication with a gas discharge passage of the humidifier base when the refilling module is removed from the humidifier base. The respiration tube connecting portion is configured to be connected to a respiration tube and deliver the humidified positive pressure gas to the respiration tube.

A humidifier assembly for a CPAP includes a base housing with a gas inlet configured to receive respiratory gas from the CPAP unit. The base housing includes a first connecting device located at a sidewall of the base housing and configured to directly, removably connect the base housing to the CPAP unit. The base housing also includes a second connecting device configured to be coupled to an air delivery hose. The humidifier assembly further includes a liquid storage container that is removably received in the base housing. The liquid storage container includes a liquid storage space configured to store liquid and a humidifying region configured to receive the respiratory gas from the gas feed opening and receive a partial amount of the liquid stored in the liquid storage space to enrich the respiratory gas with moisture.

Thermally deformable face seals and respirators including such face seals. The thermally deformable face seal structures comprise composite phase change materials that mold to the face of a user to provide a personalized but one-size-fits-all facial fit having excellent shape retention after use and long term durability. The phase change material is applied onto a base component to cover all or substantially all of the surface area of the base component and adapts to the face of the user to provide a secure, leak-free seal.

A portable air conditioning and ambient fresh air supply system that provides ambient fresh or conditioned air to a user wearing a respirator. The apparatus comprises a cabinet having an upper chamber and a lower chamber. The lower chamber holds a refrigerant air conditioning system and the upper chamber holds a blower that supplies cooled air to the surroundings. The user is able to control the temperature of the conditioned air by means of a control panel and the air flow rate by a blower control switch. An air outlet manifold supplies fresh or conditioned air through an air supply line to a respirator mask.

A breathable gas supply apparatus has a flow generator configured to pressurize a flow of breathable gas and a humidifier base unit configured to be coupled to the flow generator. A water container is configured to be removably coupled to the humidifier base unit and includes an air inlet and an air inlet passage extending into an interior of the water container from the air inlet. The air inlet passage is configured to direct the pressurized flow of breathable gas in a direction that is substantially parallel to a base of the water container. A barrier wall is provided across an outlet end of the air inlet passage and extends downward from the air inlet passage toward the water container base. In addition, a curved wall opposes both the outlet end of the air inlet passage and the barrier wall and extends downward toward the water container base. The breathable gas supply apparatus also includes a connector defining an airflow passage between an outlet of the flow generator and the air inlet of the water container.

A system for thermal regulation of a nebulizer is provided that is structured to deliver a chilled mist to the snout, muzzle, beak, or trunk of an animal. The system includes a container to house a nebulizer and a thermal material together and a mask to deliver the chilled mist to an animal. The thermal material acts to chill a liquid located inside the nebulizer in order to deliver a chilled mist to the animal for therapeutic purposes, such as initiating therapeutic hypothermia, or treating various respiratory illnesses such as croup, laryngobronchitis, and smoke inhalation.
