Tracheostomy tube with filleted flange

1. A connector for a tracheostomy tube, comprising:

an annular body having a proximal end, a distal end, and a central bore extending from the proximal end to the distal end;

a flange coupled to the annular body, the flange comprising a first flange section and a second flange section spaced apart from the first flange section, wherein the first flange section and the second flange section radially extend from the annular body and wherein the first flange section and the second flange section each comprise:

a connector end coupled to the annular body and comprising a first tapered surface having a first taper angle;

a filleted end comprising a second tapered surface having a second taper angle that is different from the first taper angle; and

a main flange section disposed between the connector end and the filleted end, wherein the main flange section comprises a top surface and bottom surface extending between the connector end and the filleted end, wherein the top surface opposes the bottom surface, wherein the bottom surface of the main flange section is curved, and wherein the first tapered surface and the second tapered surface extend away from a top surface of the main flange section.

2. The connector of claim 1 , wherein the first tapered surface of the connector end extends from the annular body distally towards the main flange section.

3. The connector of claim 1 , wherein a distal terminus of the annular body is positioned within a recess formed between bottom surfaces of the first flange section and the second flange section.

4. The connector of claim 1 , wherein the first taper angle is 25-35 degrees.

5. The connector of claim 1 , wherein the second taper angle is 30-40 degrees.

6. The connector of claim 1 , comprising a tie hole disposed entirely within and extending through the filleted end.

7. The connector of claim 1 , wherein a bottom surface of the filleted end is curved.

8. The connector of claim 1 , wherein the annular body has a sloped surface at the distal end, and wherein the connector end is adjacent to the sloped surface.

9. The connector of claim 1 , wherein a total length of each of the first and second flange sections is between approximately 1.5 inches and 2.5 inches.

10. The connector of claim 1 , wherein the bottom surface of the main flange section is curved between opposing side surfaces of the main flange section.

11. A connector for a tracheostomy tube, comprising:

an annular body having a proximal end, a distal end, and a central bore extending from the proximal end to the distal end;

a flange coupled to the annular body, the flange comprising a first flange section and a second flange section separated from the first flange section by the annular body, wherein each flange section extends radially from the annular body and comprises:

a connector end coupled to the annular body;

a filleted end; and

a main flange section disposed between the connector end and the filleted end, wherein the main flange section comprises a top surface and bottom surface extending between the connector end and the filleted end, wherein the top surface opposes the bottom surface, wherein the bottom surface of the main flange section is curved, wherein the connector end is angled in a distal direction between the annular body and the main flange section such that the bottom surface of the main flange section is positioned distally relative to the distal end of the annular body, and wherein the filleted end is angled proximally away from the top surface of the main flange section.

12. The connector of claim 11 , wherein the filleted end comprises a first tapered surface and the connector end comprises a second tapered surface.

13. The connector of claim 11 , wherein a bottom surface of the filleted end is curved.

14. The connector of claim 11 , wherein the flange section is curved at the position where the main flange section meets the filleted end.

15. A tracheostomy tube, comprising:

a cannula;

a connector comprising an annular body, a proximal end, a distal end, and a central bore extending between the proximal end and the distal end, wherein the distal end of the connector is coupled to a proximal end of the cannula;

a flange coupled to the annular body and comprising a pair of flange sections spaced apart about a circumference of the annular body, wherein an individual flange section of the pair of flange sections comprises:

a connector end coupled to the annular body;

a filleted end comprising a tie hole and a curved bottom surface; and

a main flange section disposed between the connector end and the filleted end, wherein the main flange section comprises a top surface and bottom surface extending between the connector end and the filleted end, wherein the top surface opposes the bottom surface, wherein the bottom surface of the main flange section is curved between opposing side surfaces of the main flange section, and wherein the curved bottom surface curves towards the top surface of the main flange section.

16. The tracheostomy tube of claim 15 , wherein a terminus of the filleted end is positioned proximally of a top surface of the main flange section.

17. The tracheostomy tube of claim 15 , wherein the distal end of the connector is sloped or angled.

18. The tracheostomy tube of claim 15 , wherein the filleted end comprises a first tapered surface and the connector end comprises a second tapered top surface.

19. The tracheostomy tube of claim 18 , wherein the first tapered surface comprises a taper angle of 30-40 degrees.

20. The tracheostomy tube of claim 18 , wherein the second tapered surface comprises a taper angle of 25-35 degrees.
