Abstract
A tracheal tube (e.g., an endotracheal tube) includes an inserting cannula (that may be able to swivel), and wherein the inserting cannula is connected to an elbow adaptor through a Bayonet Neill-Concelman (BNC) connection. The BNC connection may provide more secure connection of the corresponding components and may be able to withstand greater amounts of force exerted on them without becoming detached from each other. The elbow adapter may further be coupled to a pressure release valve that will alleviate pressure buildup within the tracheal tube.
Claims15
A tracheal tube assembly comprising:
- an inserting cannula having a proximal end and a distal end, the distal end having two or more pins extending laterally from a sidewall of the distal end;
- and
- an elbow adapter configured to couple the inserting cannula with a mechanical ventilator for providing air to a patient;
- a pressure release valve on the elbow adapter configured to mitigate high airway pressures that may cause disconnections or lung damage;
- and
- a Bayonet Neill-Concelman (BNC) connector configured to secure the elbow adapter to the inserting cannula, wherein a locking region of the BNC connector is transparent or translucent and is configured to change color when the BNC connector is engaged with the inserting cannula, wherein the BNC connector comprises two or more channels on the elbow adapter configured to mate with the two or more pins on the inserting cannula, wherein the two or more channels are arcs that are curved 90 degrees or more and extend longitudinally.
A tracheal tube assembly comprising:
- an inserting cannula having a proximal end and a distal end, the distal end having two or more pins extending laterally from a sidewall of the distal end;
- an elbow adapter configured to couple the inserting cannula with a mechanical ventilator for providing air to a patient;
- a Bayonet Neill-Concelman (BNC) connector on the elbow adapter configured to secure the elbow adapter to the inserting cannula wherein a locking region of the BNC connector is transparent or translucent and is configured to change color when the BNC connector is engaged with the inserting cannula, wherein the BNC connector comprises two or more channels on the elbow adapter configured to mate with the two or more pins on the inserting cannula, wherein the two or more channels are arcs that are curved 90 degrees or more and extend longitudinally;
- and
- a pressure release valve on the elbow adapter configured to release excess pressure to mitigate high airway pressures that may cause disconnections or lung damage, wherein the pressure release valve is configured to release pressure above 65 cm H2O.
A method of using a tracheal tube within a patient, the method comprising:
- inserting a cannula into a patient's mouth or nose, wherein the cannula has a proximal end and a distal end, the distal end having two or more pins extending laterally from a sidewall of the distal end;
- coupling an elbow adapter to the cannula through a Bayonet Neill-Concelman (BNC) connection, wherein the elbow adapter is coupled to a mechanical ventilator through an elbow adapter-ventilator connection, wherein the BNC connection comprises two or more channels on the elbow adapter configured to mate with the two or more pins on the inserting cannula, wherein the two or more channels are arcs that are curved 90 degrees or more and extend longitudinally;
- and
- operating the tracheal tube so that a force greater than or equal to 45 N must be applied to separate the cannula from the elbow adapter.
