Forehead and nose bridge pad for cpap interface

Номер: US20120199128A1
Автор: Karen Leigh Moore
Принадлежит: Individual

A pad is attachable to the forehead part of a CPAP face mask with pockets sewn into the body of the pad. The pad protects the forehead of the wearer and the nose bridge by a flap of material that fits between the seal of the mask and the wearer's nose bridge distributing the pressure from the mask seal. Persons with sleep apnea rely on CPAP therapy to prevent the obstruction in order to continue to breathe while sleeping. The CPAP masks appear medical and strange, especially to a new user of the device. By making the CPAP mask more comfortable with soft padding and also preventing marks and sores, it is more likely that the person will continue their therapy and improve their health. The invention is designed to be colorful, soft and comforting to help people with sleep apnea continue to get the necessary therapy.

Принадлежит: ResMed R&D Germany GmbH

The present invention provides a method for producing a filled hollow structure, preferably a cushion for a breathing mask. According to said method, a hollow structure of a first material having a cavity is produced, wherein the hollow structure has an inlet to and an outlet from the cavity. The hollow structure is positioned on a tool for holding the hollow structure. Subsequently a second material is inserted through the inlet into the cavity, while gas present in the cavity can escape through the outlet. Finally, the inlet and/or the outlet is sealed. During the step of inserting the second material through the inlet into the cavity the outlet resists flow of said second material.

Filter media for filtering gas streams (e.g., air) are described herein. In some embodiments, the filter media may be designed to have desirable properties such as stable filtration efficiency, high oil repellency, low instantaneous resistance, and/or stable service life. One or more layers of the media may have a certain value of thickness over instantaneous resistance (and/or a ratio of thickness over instantaneous resistance between two layers). The filter media described herein may be particularly well-suited for applications that involve filtering gas streams (e.g., face masks, cabin air filtration, vacuum filtration, respirator equipment), though the media may also be used in other applications.
