A humidifier that can easily control temperature and humidity in an independent manner, irrespective of a flow rate of medical gas to be supplied, is provided. The humidifier is connected to a respiratory assistance device configured to regulate or assist ventilation of a user. The humidifier is configured to add moisture to gas fed from a gas source in the form of fine particles or water vapor. The humidifier includes a liquid container configured to contain liquid containing at least water, a mist-droplet generation unit configured to generate mist droplets being fine particles of the liquid, and a water retaining member configured to hold at least a part of the mist droplets.

A high flow therapy system for delivering heated and humidified respiratory gas to an airway of a patient, the system including a respiratory gas flow pathway for delivering the respiratory gas to the airway of the patient by way of a non-sealing respiratory interface; wherein flow rate of the pressurized respiratory gas is controlled by a microprocessor.

Illnesses result from individuals having insufficient cellular energy for normal functioning and to respond to various adverse events. In addition to receiving cellular energy from the metabolism of food, living creatures are dependent upon an environmental force termed KELEA, an abbreviation for Kinetic Energy Limiting Electrostatic Attraction. This energy drives what the Applicant refers to as the Alternative Cellular Energy (ACE) Pathway. It is expressed as an added dynamic or kinetic quality of the body's fluids. Water from various natural sources has varying levels of acquired KELEA. Various means are available to increase the level of KELEA in water. KELEA activated water has medicinal qualities in the prevention and cure of illnesses attributed to insufficient cellular energy. It is typically used in individual patients being either consumed as drinking water or used topically on the skin as a spray. The present invention describes the novel use of KELEA activated water in a humidifier to increase the overall environmental level of the KELEA activated water vapor in an enclosed environment. This approach is intended to enhance the ACE pathway of those present for; prolonged periods within such an environment. This can provide both incidental and directed benefits for large groups of individuals. This method is especially applicable when using KELEA activated water which is abundantly available from certain locations, including a location specified in this application.

A respiratory humidification system includes a humidifier that is capable of electronic communication with one or more other components of the system thereby permitting transfer of data or control signals between the humidifier and other components of the system. In some systems, a flow generator, such as a ventilator, is provided to supply a flow of breathing gas. The humidifier and the flow generator are capable of electronic communication with one another. In some arrangements, an operating mode or parameter of the humidifier to be set or confirmed by the flow generator, either automatically or manually through a user interface of the flow generator. The humidifier can also utilize data provided by the flow generator or other system component, such as an incubator, to set or confirm an operating mode or parameter of the humidifier. In some arrangements, a user interface of the humidifier can display data from another system component, such as a nebulizer or pulse oximeter.

A gas conduit for respiratory apparatus includes a lumen for passage of a breathable gas to a patient and a flexible conduit wall surrounding the lumen. The flexible conduit wall has a humidification apparatus for delivering water vapour into the gas passing through the lumen.

A unitary humidity oxygen nasal prong cannula assembly includes two oxygen supply assemblies. Each assembly includes a body (5) having an oxygen inlet (7) and a prong (9) extending from the body (5). The prong (9) is configured for insertion into a nostril of a patient. The body and the prong define a passageway for supplying oxygen to the nostril of the patient. The assembly also includes a heat and moisture exchange (“HME”) device (13) for providing moisture and heat to cold oxygen supplied to the cannula from an oxygen concentrator. The HME device forms a part of the body and is configured so that cold oxygen passing through the passageway passes through the HME device.

A humidifier for humidifying a flow of pressurized breathable gas to be delivered to a patient includes a dock and a humidification tub. The dock includes a device compartment that is configured to at least partially removably receive an RPT device that is configured to supply the flow of pressurized breathable gas. The dock also includes a humidification compartment that is fluidly connected to the device compartment. The humidification tub is configured to contain a supply of water and is at least partially removably received within the humidification compartment so that, in an operational configuration, the humidification tub is arranged to receive the flow of pressurized breathable gas and output the flow of pressurized breathable gas with increased humidity. The dock also includes a heater fixed to the humidification tub. The heater is configured to heat the supply of water.

A humidifier system for humidifying a microenvironment in a neonatal incubator includes a reservoir configured to hold water to be evaporated for humidifying the microenvironment. A movable heating element is positioned at a surface level of the water inside a heating chamber so as to heat the water at the surface level inside the heating chamber. The heating element is configured such that it is moved downward within the heating chamber so as to maintain the heating element at the surface level of the water as an amount of water in the reservoir decreases.

Over-enthalpy conditions when using a respiratory and/or surgical humidifier system can be prevented. A heating element power in an inspiratory conduit can be limited based at least in part on one or more parameters of the gases flow, and/or on an ambient temperature. The limit on the heating element power in the inspiratory conduit can be achieved using a processor and/or protection circuit(s) located outside the processor. For example, the system can use the processor to determine and/or apply the limit as a level of protection and use the protection circuit(s) as another level of protection.

A humidifier tub for a respiratory apparatus is configured to deliver pressurized breathable gas to a patient's airways. The humidifier tub includes a base and a side wall defining a reservoir for containing a supply of liquid to be evaporated. In addition, the container is made of a first material. The humidifier tub also includes a heating element provided inside the container and covered by a layer. The layer includes a second material different from the first material.
