Abstract
Various embodiments of tracheostomy tube assemblies including a cannula and a flange are provided. One of the cannula and the flange includes a pair of slots and the other of the cannula and the flange includes a pair of protrusions adapted to be received by the pair of slots. The pair of slots and the pair of protrusions enable two or more degrees of freedom of movement of the flange with respect to the cannula.
Claims18
A tracheostomy tube assembly, comprising:
- a cannula comprising a distal end and a proximal end, the distal end being adapted to be inserted into a patient's trachea and the proximal end comprising a collar comprising a first slot and a second slot;
- and
- a flange member comprising an aperture configured to receive the proximal end of the cannula, a first protrusion adapted to be received by the first slot, and a second protrusion adapted to be received by the second slot, wherein the first protrusion and the second protrusion extend into the aperture from opposite surfaces of the flange member, wherein the first protrusion and the second protrusion of the flange member are configured to engage with the first slot and the second slot of the cannula to enable the flange member to move with two or more degrees of freedom with respect to the cannula when the tracheostomy tube assembly is positioned for operation such that the distal end of the cannula is inserted into the patient's trachea and the flange member is engaged with the patient's neck to support the tracheostomy tube assembly and maintain the flange member outside of the patient's body, wherein one of the two or more degrees of freedom of movement comprises movement of the flange member longitudinally with respect to the length of the cannula between the distal end and the proximal end of the cannula.
A tracheostomy tube assembly, comprising:
- a cannula comprising a distal end and a proximal end, the distal end being adapted to be inserted into a patient's trachea and the proximal end comprising one of a pair of slots or a pair of pins;
- and
- a flange member comprising the other of the pair of slots configured to engage with the pair of pins on the cannula, or the pair of pins configured to engage with the pair of slots on the cannula, and wherein when the tracheostomy tube assembly is positioned for operation such that the distal end of the cannula is inserted into the patient's trachea and the flange member supports the tracheostomy tube assembly via engagement with the patient's neck to maintain the flange member outside of the patient's body, the pair of slots and the pair of pins are configured to enable two or more degrees of freedom of movement of the flange member with respect to the body, wherein one of the two or more degrees of freedom of movement comprises movement of the flange member longitudinally with respect to the length of the cannula between the distal end and the proximal end of the cannula.
A tracheostomy assembly, comprising:
- a cannula comprising a distal end and a proximal end, the distal end being adapted to be inserted into a patient's trachea;
- a collar coupled to the proximal end of the cannula;
- and
- a flange coupled directly to the collar or the cannula and comprising a pivoting means that permits pivotal movement about a transverse axis in two or more degrees of freedom of movement of the flange with respect to the collar or the cannula when the tracheostomy tube assembly is positioned for operation such that the distal end of the cannula is inserted into the patient's trachea and the flange member is engaged with the patient's neck to support the tracheostomy tube assembly and maintain the flange member outside of the patient's body, wherein one of the two or more degrees of freedom of movement comprises movement of the flange member longitudinally with respect to the length of the cannula between the distal end and the proximal end of the cannula.
