ABSTRACT:
The present invention relates to improved methods and apparatus for the delivery of respiratory therapy in the treatment of respiratory disorders and abnormalities, such as apnea and other sleep disorders. A qualified professional takes a moulage of a patient's facial skeletal structure and therefrom casts a custom hard shell of the imprinted facial features. Upon the shell hardening, the shell is then lined and further manipulated and a soft gasket interface attached to the mask where the mask interfaces with the patient's face. The contact medium, coupled with the custom hard shell, allows for a vacuum-like seal. A section is then cut and an area sufficient to allow the attachment of the respiratory devices for the supply of air is created. The apparatus is further held in place by means of a strap-like device having one or more contact points upon the present invention. The present disclosure overcomes the prior devices, enhancing seal, comfort effectiveness and patient compliance.
