<p><P>PROBLEM TO BE SOLVED: To provide a nasal mask preventing the falling of droplets formed by dew-condensation of wet components contained in respiration gas on a mask inner face onto the face of a patient in the nasal mask supplying the respiration gas to the patient. <P>SOLUTION: The nasal mask is formed by either one of the following solutions: (1) the nasal mask is provided with a droplet guide groove to prevent the growth of small droplets from merging and is constituted to trap the droplets moving downward; (2) a droplet movement prevention means is provided inside the nasal mask to prevent the growth of the droplets; (3) the inside of the nasal mask is formed to have hydrophilicity to prevent the formation of droplet; and, (4) the inside of the nasal mask is formed to have water-shedding quality to move the droplets downward while they are small. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
