  • Patent number: 11260192
    Abstract: A respiratory mask can be used to provide therapy to patients who also require a nasogastric (NG) tube. The mask seal can include a path that is designed to deform around an NG tube or other without lifting the mask away from a patient's face. The deforming path can help to minimize gaps that form between the patient's face and the mask seal as a result of the tube, thus reducing leaks and improving the efficacy of the treatment.

  • Patent number: 10898669
    Abstract: The present invention discloses a carbon dioxide inhalation treatment device for central sleep apnea comprising a blower, a gas cylinder filled with carbon dioxide (CO2), an airbag, a mask, and a detection mechanism for detecting the central apnea by measuring the electromyographic activity of the chest wall muscles. The mask is provided with multiple holes providing a communication between the inside and outside of the mask in order to prevent any sense of resistance of breathing and to provide greater control of inspired CO2. Inspired CO2 from a gas mixture containing also a minimum 20% O2 is driven by air using a blower into a mixing chamber. This carbon dioxide inhalation treatment device for central sleep apnea can provide a stable, mild level of carbon dioxide for patients with central sleep apnea, thus by preserving respiratory drive correcting central sleep apnea without increasing the arousal and microarousal frequency.

    Abstract: A patient interface device uses a pressure flap which extends inwardly from an outer edge of a mask of the device. The pressure flap is for contacting the skin of the patient to provide a seal or partial seal between the mask volume and the ambient surroundings. The pressure flap includes a cavity area which is exposed to a reduced pressure compared to the mask volume. This assists in keeping the pressure flap pressed against the patient's skin, and thereby maintain a large contact area. This in turn gives a reduction in local high pressure areas.

  • Patent number: 9974913
    Abstract: A seal device or gasket assembly usable with respiration or ventilation mask systems and that is preferably at least one of adhesive or deformable. The gasket is disposed between the mask and the wearer and reduces the escape of respiration gases between the perimeter edge interface of the mask with the anatomy of the wearer and limits exposure of the epidermis located within the perimeter of the mask and between the mask and the wearer to the respiration gas flows. The mask system is particularly useful for improving communication of the respiration gases for those wearers having facial hair, abnormal dontia, and/or other abnormal facial features.
