Abstract

A treatment system includes a vaporizer, a tent for maintaining a high humidity environment in a chamber around at least the upper body of an individual under treatment, and a flexible conduit from the vaporizer to the chamber. The tent includes a supporting framework and a porous fabric supported by the framework. The fabric, preferably a polyester tricot, consists of multifilament strands woven to provide a porosity of about fifty percent. So constructed, the fabric is air permeable, yet tends to block a substantial percentage of moisture droplets suspended in the air, thereby increasing the relative humidity inside the therapy tent to a value substantially above ambient relative humidity, for example over ninety percent while ambient levels outside the tent remain at about fifty percent. As a result, a therapeutic, high humidity environment is maintained about the patient, without the need for oxygen supplies, pumps, blowers or other special equipment. Thus, treatment is provided at substantially lower cost and at less risk to the patient.
