Document Type and Number:
Japanese Patent JP2021108669
Kind Code:
A
Abstract:
To solve problems of a conventional mask, problems of 1) the mask gets wet by the moisture of exhalation to deteriorate air permeability; 2) exhalation and clean air are mixed in the mask, simultaneously sucking carbon dioxide and moisture to cause stuffiness; 3) ambient air comes in to lower filtration performance; 4) the mask gets wet by exhalation, which causes discomfort and impurity by proliferation of various germs; 5) exhalation makes the mask smell inside to produce unpleasantness; and 6) a method of inserting a nostril tube into a nostril is suffocative because of a small capacity of a filter.SOLUTION: The present invention is a nostril mask in which a nostril header having nostril tubes is covered with a mask. The nostril header, which is a respiratory apparatus, has an inhalation port and an exhalation port, with the inhalation port having a check valve for inhalation, and with the exhalation port having a check valve for exhalation. The apparatus is structured: 1) there is no mixture of exhalation and clean air inside the mask; 2) air permeability of the mask is improved to dissolve stuffiness; 3) smell and increase in humidity inside the mask by exhalation is prevented to solve unpleasantness.SELECTED DRAWING: Figure 1
