ABSTRACT:
A disposable, inhalation-therapy, container in which a chamber for liquid is defined between the sides, top and bottom of the container by transverse upper and lower, flexible, multi-slitted partitions, spaced from the top and bottom of the container. The partitions are porous when flexed by inhalation gas pressure and impervious when not so flexed. Inhalation gas under pressure is introduced into the space between the container bottom and the lower partition and flexes it to porosity, the gas bubbling through theliquid chamber is silenced and slowed by the upper partition as it is flexed into porosity by the gas pressure to better humidify the escaping gas for inhalation. When the therapy ceases, inhalation gas pressure is shut-off and the sterile liquid is resealed by the unflexed partitions in the liquid chamber.
