Abstract: A tracheal tube assembly includes an outer cannula configured to be positioned in a patient airway and an inner cannula configured to be disposed inside the outer cannula. The tracheal tube assembly further includes a flange member secured about the outer cannula, and an outer cannula connector coupled to a proximal end of the outer cannula. The inner cannula includes a proximal end region with features that facilitate insertion and/or removal.

Abstract: A tracheal tube system includes a tracheal tube assembly having a cannula configured to be positioned in a patient airway, and a connector coupled to the proximal end of the cannula. The tracheal tube assembly further includes a flange member secured about the cannula. The flange member includes an interior face configured to be disposed onto a patient neck when in use and a first plurality of protrusions disposed on top of the interior face, wherein the cannula and the connector form a contiguous passageway for exchanging fluid with the patient airway in operation.

Abstract: A speaking valve includes a hollow body configured to be secured to a connector of a tracheostomy system disposed in a patient. The speaking valve further includes a cap that houses a valve member, which enables the speaking valve to act as a one-way check valve. The valve member, hollow body, or other components of the valve may include a material that undergoes a chemical changed when exposed to moisture, i.e., a hydrosensitive material. Particularly, the hydrosensitive material may exhibit a color change when exposed to moisture. As such, the hydrosensitive material may be useful in providing a visual indication of the saturation and/or moisture level of the speaking valve.

Abstract: A pilot balloon assembly for a tracheal tube includes a pilot balloon guard for a pilot balloon. The pilot balloon guard includes an enclosure having walls that define an interior volume that is greater than an interior volume of a pilot balloon. The pilot balloon is received by the enclosure and inflates within the enclosure to indicate inflation of a cuff of the tracheal tube. The pilot balloon guard enclosure absorbs externally applied forces to prevent transfer of the externally applied forces to the pilot balloon.
