ABSTRACT:
A dehumidifying device for use in a ventilator for reducing the relative humidity of the expired air of a patient has a plurality of tubes, permeable to moisture, arrayed in a bundle and encircled by a loosely wound spiral harness between a first connection section and a second connection section in the dehumidifying device. When gas expired by the patient reaches the dehumidifying device, the water vapor therein diffuses into the tubes, and the relative humidity of expired gas is decreased.
