  • Patent number: 9216263
    Abstract: A breath intake valve is connected to a tracheostomy tube inserted into a patient's trachea. The inner end of the valve attaches to the tracheostomy tube. An apertured disk endpiece with an O-ring around its circumference is releasably set into the outer end of the tubular valve body. A floppy diaphragm overlying the inner face of the disk endpiece functions as an intake valve to allow patient inhalation and air intake, and as a check valve to block patient exhalation, thereby to redirect it to the patient's larynx, sinuses, and mouth for normal speech. The O-ring gives way to forceful patient exhalation to release the disk endpiece from the tubular valve body. The disk endpiece is tethered to the breath intake valve body to prevent misplacement of the endpiece after such a release. The breath intake valve is itself likewise tethered to the tracheostomy tube to prevent its misplacement after any disconnection.
