Abstract

A medical treatment gas humidifier for providing a patient with a relatively highly stabilized and humidified medical treatment gas. The humidifier comprises a liquid- and gas-tight container the inside of which is divided with a gas selectively permeable membrane into a water region where humidifying water stays and a gas region where the medical treatment gas sent from medical treatment gas supply means stays. The medical treatment gas staying in the gas region is humidified with water vapor vaporized from the water region, and the humidified medical treatment gas is sent forcedly by pressure to the patient. The water region has a water inlet for liquid- and gas-tightly connecting a water supply container and a pressure regulation pipe. The water supply container has a water storage unit disposed in a position higher than the humidifier so as to supply a predetermined amount of water to the humidifier. The pressure regulation pipe extends to a gas staying space over a water storage unit of the water container. The gas region has a gas outlet for sending the humidified medical treatment gas to the patient forcedly by pressure and a connection port for connection of a pressure regulation pipe for returning, if an excessive pressure of the medical treatment gas is loaded inside the humidifier, the excess pressure to the water supply container.
