  • Respiratory mask
    Patent number: 7121279
    Abstract: A respiratory mask is reduced in size to better fit patients with smaller faces by folding accordion folds of the mask. An adjustment member allows for selective folding of the accordion folds, thereby determining the size of the mask. The respiratory mask can thus be adjusted to fit both larger and smaller persons.

  • Respiratory mask
    Patent number: 6851428
    Abstract: A respiratory mask is reduced in size to better fit patients with smaller faces by either (a) folding one or more accordian folds formed in an upper portion of the mask, or (b) tearing away a part of the upper portion of the mask. The respiratory mask for adult patients can thus be adjusted to fit smaller adults and larger children. The respiratory mask for children can thus be adjusted to fit smaller children. A ball joint swivel connector is provided to connect the gas inlet of the masks to the hose connection for respiratory or nebulizer treating gases or aerosols.
