A device and a process for the heating and humidification of gas, especially respiratory gas. Fluid from a fluid reservoir is supplied to a sprinkling type chamber where, for the purpose of humidification, it is moved through the gas. The point is that the fluid is heated by a temperature controlled heater to a preset temperature. In addition to the description of the device, a description of the process underlying the operation of the device is described.

A humidifier device according to claim 1, wherein said pump is adapted to feed the fluid from the fluid reservoir to the humidification surface, the humidification surface and the fluid reservoir being connected in a circuit. 5. A humidifier device according to claim 1, wherein the humidification surface includes a sieve surface configured to distribute the fluid within the chamber. 6. A humidifier device according to claim 1, further comprising a bottom chamber to collect the fluid that has passed through the humidification surface. 7. A humidifier device according to claim 6, wherein the fluid collected in the bottom chamber is recirculated back to the fluid reservoir. 8. A humidifier device according to claim 2, wherein the filling material includes knitted aluminium, stainless steel wool, or metal pearls. 9. A humidifier device according to claim 1, wherein the humidification surface is configured to provide a large surface area for humidity exchange. 10. A respiratory system for providing a supply of pressurized humidified gas to a patient, the system comprising: a humidifier device according to claim 1 to humidify a supply of gas;a gas flow generator coupled to the humidifier device configured to control the pressure of the supply of gas; anda patient interface device coupled to an air delivery tube for delivery of the pressurized humidified supply of gas to the patient. 11. A respiratory device according to claim 10, wherein the gas flow generator is provided downstream of the humidifier device. 12. A respiratory device according to claim 11, wherein the supply of gas for the humidifier device is provided from a gas reservoir. 13. A respiratory device according to claim 10, wherein the gas flow generator is provided upstream of the humidifier device. 14. A process of humidifying a supply of gas comprising: providing a flow of gas between a gas inlet and a gas outlet of a humidification chamber;providing a supply of heated fluid to a humidification surface within the humidification chamber, the gas flow configured to flow through the humidification surface between the gas inlet and the gas outlet; anddriving the heated fluid to move through the humidification surface in a direction substantially opposite to the direction of the gas flow,wherein the heated fluid is provided to the humidification surface from a fluid reservoir via a drive device,wherein the drive device pumps the heated fluid to the humidification surface. 15. A process according to claim 14, wherein the flow of gas is provided by a gas flow generator provided upstream of the gas inlet. 16. A process according to claim 14, wherein the flow of gas is provided by a gas reservoir provided upstream of the gas inlet. 17. A process according to claim 16, wherein the humidification chamber is pressurized.
