Anti-kink and ergonomic nasal cannula device

A nasal cannula device for delivering breathing gas, comprising:

• a flexible tube having an inner surface and an outer surface;
• one or more anti-kink devices attached to a distal end of the flexible tube that connects to a connection adapter, so that the one or more anti-kink devices provide support to the flexible tube to prevent kinking of the flexible tube;
• one or more ear protection devices attached to or integral with a portion of the flexible tube that is configured to contact a user's ear, wherein the one or more ear protection devices comprise a soft material to mitigate skin irritation of the user's ear;
• wherein the one or more anti-kink devices extend from the connection adapter and attach to the one or more ear protection devices and wherein the one or more anti-kink devices are configured to be selectively attachable and detachable to surround and conform to and prevent kinking along the flexible tube;
• a plurality of first sensors disposed within the one or more anti-kink devices and configured to monitor and measure pressure, wherein at least one of the plurality of first sensors comprises a pressure sensor configured to detect a kink in the flexible tube;
• at least one second sensor positioned proximate the one or more ear protection devices, the at least one second sensor configured to detect a biological analyte on the user's skin;
• and
• a processing unit in communication with the plurality of first sensors and the at least one second sensor to monitor and adjust an oxygen level to maintain a predetermined oxygen supply delivered to a user during movement and exertion;
• and
• wherein the processing unit is configured to receive and process signals generated by the at least one sensor of the plurality of first sensors to detect the kink in the flexible tube.
