CPAP mask, NPPV mask with notches or holes for attaching non-woven fabric with water absorption and water retention, and CPAP mask and NPPV mask with non-woven fabric with water absorption and water retention

摘要

To provide a CPAP mask and an NPPV mask as a CPAP mask to be used for treatment of a sleep apnea syndrome, and an NPPV mask to be used for a non-invasive positive pressure ventilation therapy, allowing mounting a dew condensation water absorbing and retaining nonwoven fabric which prevents water droplets generated due to dew-condensation of wetting components contained in respiration gas and wetting components contained in respiration gas of a user himself/herself inside the mask from dropping and invading to the face and nostril of a patient, and also controls humidity of respiration gas.SOLUTION: A mask 1 (CPAP mask, NPPV mask) is provided with a notch or hole 2 for mounting a dew condensation water absorbing and retaining nonwoven fabric 3, as shown in figure 1. The dew condensation water absorbing and retaining nonwoven fabric 3 is mounted by using the notch or the hole 2 so as to absorb and retain dew condensation water generated inside the mask 1, and prevent water droplets generated due to dew condensation inside the mask 1 from dropping and invading to the face or nostril of a user of the mask 1. Humidity of respiration gas is controlled by the dew condensation water absorbing and retaining nonwoven fabric 3 mounted on the mask 1.SELECTED DRAWING: Figure 1
