Abstract

A molded tracheostomy tube may provide enhanced comfort for a patient. A unitary molded coating over areas of the tracheostomy tube that come into contact with the patient'"'"'s skin may prevent irritation. Further, the overmolding manufacturing process may allow the tracheostomy tube assembly to incorporate features that allow for greater ease of movement for a patient, such as features that allow flexing at the connection point of the tracheostomy tube to other medical devices.

Claims

1. A tracheostomy tube 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 flange member molded over the proximal end of the cannula; and

a conduit disposed on the flange member in communication with the cannula, wherein the conduit is adapted to operatively connect to a medical device.

2. The tracheostomy tube of claim 1, comprising an inflatable cuff disposed on cannula.

3. The tracheostomy tube of claim 1, wherein the medical device comprises a ventilator.

4. The tracheostomy tube of claim 1, comprising a disposable cannula lining adapted to be slidably insertable into the cannula.

5. The tracheostomy tube of claim 1, wherein the conduit comprises a grooved portion adapted to allow the conduit to flex relative to the flange member.

6. The tracheostomy tube of claim 1, wherein the conduit is adapted to be substantially orthogonal relative to the flange member absent any deforming forces.

7. The tracheostomy tube of claim 1, wherein the flange member comprises a flexible radial section substantially surrounding the conduit adapted to allow the conduit to flex relative to the flange member.

8. The tracheostomy tube of claim 1, wherein the flange member comprises at least one groove adapted to allow the conduit to flex relative to the flange member.

9. The tracheostomy tube of claim 1, wherein the flange member comprises a thermoplastic elastomer, a polyvinylchloride, or a polyurethane.

10. The tracheostomy tube of claim 9, wherein the thermoplastic elastomer comprises at least one of a styrenic block copolymer, thermoplastic vulcanizate alloy, thermoplastic polyurethane, silicone, ethyl vinyl acetate, elastomer alloy, or a combination thereof.

11. The tracheostomy tube of claim 1, wherein the proximal end of the cannula comprises a flared region.

12. The tracheostomy tube of claim 11, wherein the flared region comprises a plurality of perforations.

13. The tracheostomy tube of claim 1, wherein the conduit is integral with the flange member.

14. The tracheostomy tube of claim 1, wherein the flange member is permanently coupled to the proximal end of the cannula.

15. The tracheostomy tube of claim 1, wherein the flange member is chemically bonded to the proximal end of the cannula.

16. A method of manufacturing a tracheostomy tube comprising:

providing a cannula comprising a distal end and a proximal end, the distal end being adapted to be inserted into a patient'"'"'s trachea;

molding a flange member over the proximal end of the cannula such that the proximal end of the cannula is coupled to the flange member; and

disposing a conduit disposed on the flange member in communication with the cannula, wherein the conduit is adapted to operatively connect to a medical device.

17. The method of claim 16, comprising disposing an inflatable cuff on the cannula.

18. The method of claim 16, comprising providing a disposable cannula lining adapted to be slidably insertable into the cannula.

19. The method of claim 16, comprising molding a grooved portion on the conduit adapted to allow the conduit to flex relative to the flange member.

20. The method of claim 16, wherein disposing the conduit comprises molding the conduit along with the flange member.

21. The method of claim 16, comprising providing a flexible radial section on the flange member substantially surrounding the conduit adapted to allow the conduit to flex relative to the flange member.

22. The method of claim 16, comprising providing at least one groove on the flange member adapted to allow the conduit to flex relative to the flange member.

23. The method of claim 16, wherein the flange member is molded over the proximal end of the cannula by injection molding, insert injection molding, or two-shot molding.

24. The method of claim 16, comprising providing a second conduit extending from the first conduit.

25. The method of claim 16, wherein the proximal end of the cannula comprises a flared region.

26. The method of claim 25, wherein the flared region comprises a plurality of perforations.

27. A method of sealing a patient'"'"'s trachea comprising:

inserting a tracheostomy tube into a patient'"'"'s trachea, wherein the tracheostomy tube comprises;

a cannula comprising a distal end and a proximal end, the distal end being adapted to be inserted into a patient'"'"'s trachea;

a flange member molded over the proximal end of the cannula; and

a conduit disposed on the flange member in communication with the cannula, wherein the conduit is adapted to operatively connect to a medical device.

28. The method of claim 27, comprising inflating a cuff disposed on cannula.

29. The method of claim 27, wherein the medical device comprises a ventilator.

30. The method of claim 27, comprising inserting a disposable cannula lining into the cannula.

31. The method of claim 27, wherein the conduit comprises a grooved portion adapted to allow the conduit to flex relative to the flange member.

32. The method of claim 27, wherein the flange member comprises a flexible radial section substantially surrounding the conduit adapted to allow the conduit to flex relative to the flange member.

33. The method of claim 27, wherein the flange member comprises at least one groove adapted to allow the conduit to flex relative to the flange member.

34. The method of claim 27, wherein the proximal end of the cannula comprises a flared region.

36. A tracheostomy tube mold form comprising:

a mold cavity defining a flange member;

a mold cavity defining a conduit adapted to be disposed on the flange member in communication with the cannula; and

an opening in the mold form adapted to receive a cannula comprising a distal end and a proximal end, wherein the proximal end of the cannula is adapted to be inserted into at least a portion of the mold cavity defining the flange member.

35. The method of claim 36, wherein the flared region comprises a plurality of perforations.

37. A unitary molded tracheostomy tube assembly comprising:

a cannula adapted to be inserted into a patient'"'"'s trachea comprising a distal end and a proximal end;

a flange member disposed on the proximal end of the cannula; and

a conduit disposed on the flange member in communication with the cannula, wherein the conduit is adapted to operatively connect to a medical device, and wherein the cannula, the flange member, and the conduit comprise a unitary molded structure.
