International Classification:

A61M 16/06
A61M 39/10

US Classification:

12820216, 12820624

Abstract:

A non-invasive ventilation patient interface comprises a frame, a facial skin interface, and a self-sealing tube insertion region. The frame is configured for coupling with a head strap system, where head strap system is configured for supplying a securing force to secure the patient interface in a position over a respiratory opening of a patient. The facial skin interface is coupled with the frame and configured for interfacing with facial skin of the patient and sealing the patient interface about the respiratory opening in response to the securing force. The self-sealing tube insertion region is coupled with the facial skin interface and configured for self-sealing about a tube disposed between the facial skin and the facial skin interface, such that the securing force is diverted around the tube while the tube is inserted in the self-sealing tube insertion region.

International Classification:

A61M 16/06

US Classification:

12820512

Abstract:

A non-invasive ventilation patient interface comprises a fresh gas entry port, an exhaust gas vent port, and a filter media disposed in the exhaust gas vent port. The fresh gas entry port is configured for coupling with a fresh gas supply. The exhaust gas vent port is configured for allowing expulsion of exhaust gas from the patient interface in response to exhalation of a patient. The filter media is configured for filtering contagious from the exhaust gas, diffusing the exhaust gas, and controlling an expulsion flow of the exhaust gas through the exhaust gas vent port.

International Classification:

A61M 16/06

US Classification:

12820525, 12820624, 12820622

Abstract:

A non-invasive ventilation patient interface comprises a fresh gas entry port, a frame, and a zygomatic facial interface. The fresh gas entry port is configured for coupling with a fresh gas supply. The frame is configured for coupling with a head strap system, wherein the head strap system is configured for supplying a securing force to secure the patient interface in a position over a respiratory opening of a patient. The zygomatic facial interface is coupled with the frame and configured for spreading the securing force away from a nasal bridge of the patient and onto left and right zygomatic arch regions of the patient.

International Classification:

A61M 16/06

US Classification:

12820624

Abstract:

A ventilation mask comprises a corrugated flexible seal, and a plurality of ridges disposed along the corrugated flexible seal. The corrugated flexible seal is configured for establishing a fluid seal between the ventilation mask and a patient, and for allowing facial movements of the patient while maintaining the fluid seal. The plurality of ridges disposed along the corrugated flexible seal is configured for physical contact with the patient.

International Classification:

A61B 5/097
A61B 6/00

US Classification:

600473, 600532

Abstract:

A carbon-dioxide sampling system for accurately monitoring carbon dioxide in exhaled breath. The system includes a ventilator. The ventilator is configured to ventilate a patient with respiratory gases. The ventilator includes a carbon-dioxide sampling control unit and a carbon-dioxide analyzer. The carbon-dioxide sampling control unit is configured to control the timing of sampling of carbon dioxide in the exhaled breath of a patient, and to control the timing of the analysis of exhaled gases by the carbon-dioxide analyzer.

International Classification:

A61B 5/097

US Classification:

600532

Abstract:

A carbon-dioxide sampling device for non-invasively measuring carbon dioxide in exhaled breath. The device includes a breath-sampling chamber and a carbon-dioxide collector. The breath-sampling chamber is configured to be disposed over a respiratory opening of a patient, and is also configured to seal with the patient's face preventing unintentional leakage of respiratory gases from the chamber. The carbon-dioxide collector is disposed in the breath-sampling chamber in fluid dynamic isolation from the respiratory gases. Moreover, the carbon-dioxide collector is configured to be disposed in proximity to, and outside of, the respiratory opening of the patient, and to collect a sample of exhaled breath from the patient.
