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 a connector coupled to a proximal end of the outer cannula. The connector is configured to provide a view of the inner cannula, and the inner cannula and the connector form a contiguous passageway for exchanging fluid with the patient airway in operation.

Abstract: A filtering device for use in breath sampling including a filter configured to absorb moisture, a first connector configured to allow connection of a user interface to the filtering device, and a second connector configured for connection to the gas analyzer; wherein the filter is essentially flat, such that when the filtering device is connected to a gas analyzer, the filter is in-line with a panel of the gas analyzer; and wherein a circumference of the first and second connectors are smaller than a circumference of the filter.

Abstract: A breath sampling line connector including a housing and a first mating plate, the first mating plate having a non-circular orifice and a geometric feature, the geometric feature configured to determine an alignment of the first mating plate relative to a second mating plate of a mating connector; wherein the alignment determines a cross sectional area of the non-circular orifice.

Abstract: The present disclosure describes systems and methods that utilize a tracheal tube with an integral visualization device, such as a camera. The tracheal tube system may include a camera apparatus or other visualization device that is associated with a lumen formed in the wall of the tube. In addition, the camera apparatus may be positioned within a holder associated with a distal end of the tracheal tube that functions to hold and position the optical components of the camera relative to the tube and provides an acceptable profile for comfortable intubation. Further, the camera apparatus and its associated holder may include additional components, such as integral light sources and flushing or cleaning devices to remove any buildup from the camera or optical components.

Abstract: An airway access device having a first end including a first connector configured to be connected to an airway device; a second end including a second connector configured to be connected to a ventilation machine; an airway channel extending between said first and second ends; and at least two access ports configured to allow access into a patients airway without disconnecting the ventilation machine.

Abstract: Various embodiments of tracheostomy tube assemblies including a cannula, a cap, and a flange are provided. The cannula includes a distal end and a proximal end, the distal end being adapted to be inserted into a patient's trachea. The annular cap includes an annular body having a first surface adapted to be received into the proximal end of the cannula to retain a portion of the cap in the annular body. The flange member includes a second surface that engages the proximal end of the cannula such that the proximal end of the cannula is retained between the second surface of the flange member and the first surface of the annular cap. The flange member also includes a third surface adapted to engage an inner surface of the annular body of the annular cap to retain the flange member between the annular cap and the proximal end of the cannula.

Abstract: Various embodiments of a tracheal tube having a suction lumen are provided. For example, the suction lumen may be associated with two spaced apart pressure transducers, whereby a pressure drop between the transducers indicates that the suction lumen is free of blockages and a characteristic lack of pressure drop and/or particular pressure curve is indicative of a blockage. In addition, embodiments may include a tracheal tube with sensors configured to sense a buildup of secretions. The sensors may be located proximate to an opening in the suction lumen. In other embodiments, a blockage-clearing system for a suction lumen may be provided that blows air into the suction lumen to clear blockages. In particular, in certain embodiments, the blockage-clearing system may operate to create its own pressurized air source by utilizing the pressure change created in the suction line by a blockage.

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.

Abstract: A tracheal tube assembly includes a cannula connector that includes a cannula connector cap coupled to a flange assembly. The flange assembly is in turn coupled to a cannula. The flange assembly includes a portion that extends through slots formed at or near a proximal end of the cannula connector cap. The flange assembly may be overmolded.
