Humidifier cartridge for low-flow oxygen therapy

Humidifier for low-flow oxygen therapy

A method for drying a gas sample comprises flowing purge gas over the exterior of tubes of a perfluorosulfonic acid membrane and flowing the gas sample through interior of tubes, wherein the drying operation is conducted under deep vacuum and with the purge gas flowing at a rate that is typically less than that of the gas sample being dried.

Method for a portable sampling system

Humidifier base for low-flow oxygen therapy

A system for humidifying oxygen for low-flow oxygen therapy includes a volume-adaptable water reservoir that contains, in addition to water, a water-vapor-permeable membrane.

Low-flow oxygen therapy humidifier and method

A hybrid cooler/dryer that conditions a sample gas includes a heat exchanger, a condensate-removal device, and a membrane dryer. In some embodiments, the hybrid cooler/dryer also includes passive cooling, as embodied by an air amplifier and heat sink, or a length of tubing that exposes the sample gas to ambient temperature. The hybrid cooler/dryer requires no electrical power.

Hybrid cooler/dryer and method therefor

A portable sampling system includes a heated probe, an input/output ('I/O') system, and one membrane dryer in the form of a conduit that couples the probe to the I/O system. The dryer has purge gas flowing over the drying membrane and a gas sample flowing through the drying membrane, which is in the form of tubes of a perfluorosulfonic acid material, and wherein the dryer is operated in some embodiments under deep vacuum and with the purge gas flowing at a rate that is typically less than that of the gas sample being dried.
