CLAIMS

1. A tracheostomy tube pack including an outer tracheostomy tube (1 , 1 ', 1 "), an inner cannula (30, 30', 30") adapted for removable insertion within the outer tube and packaging (40, 40', 40", 50) within which the outer tube (1, , 1") and the inner cannula are enclosed, characterised in that the outer tracheostomy tube is provided with non-alphanumeric visible marking (22) of a particular characteristic in a region (20) of the tube visible externally of the patient when the tube is inserted in a patient and that is indicative of a property of the tube, and that the inner cannula (30, 30', 30") and the packaging (40, 40', 40", 50) also are both provided with a

corresponding marking (43, 43', 43", 54, 61) of the same characteristic as that on the tube.

2. A pack according to Claim 1 , characterised in that the property of the tube ( 1 , 1 ' , 1 " ) is its size.

3. A pack according to Claim 1 or 2, characterised in that the characteristic of the

visible marking is its colour.

4. A pack according to Claim 1 or 2, characterised in that the characteristic of the

visible marking is its pattern.

5. A pack according to any one of the preceding claims, characterised in that the region of the tube on which the marking is provided is a flange (20) of the tube (1, , 1").

6. A pack according to any one of the preceding claims, characterised in that the

packaging (40, 40', 40") includes a tray (41, 4 , 41") with a peel-off sealing sheet (42).

7. A pack according to Claim 6, characterised in that the packaging includes an outer carton (50) in which the tray (41, 4 Γ, 41 ") is contained.

8. A tracheostomy tube assembly including an outer tracheostomy tube (1, Γ, 1") and an inner cannula (30, 30', 30") adapted for removable insertion within the outer tube, characterised in that the outer tracheostomy tube (1, 1 ', 1 ") is provided with a non- alphanumeric visible marking (22) of a particular characteristic in a region of the tube visible externally of the patient when the tube is inserted in a patient and that is indicative of a property of the tube, and that the inner cannula (30, 30', 30") is also provided with a corresponding marking (33) of the same characteristic as that on the tube.

9. A tracheostomy tube assembly according to Claim 8, characterised in that the

property of the tube (1 , 1 ', 1 ") is its size.

10. A tracheostomy tube assembly according to Claim 8 or 9, characterised in that the region of the tube on which the marking is provided is a flange (20) of the tube (1 , 1 ', 1").

11. A set of a plurality of tracheostomy tube assembly packs each comprising packaging (40, 40', 40") containing an outer tracheostomy tube (1, , 1") and an inner cannula (30, 30', 30") for use with the outer tube, at least two of the packs in the set containing tracheostomy tubes that differ in size between the packs, characterised in that the packaging (40, 40', 40") , outer tracheostomy tube (1, 1 ', 1 ") and inner cannula (30, 30', 30") in each pack are each provided with non-alphanumeric visible marking (22, 33, 43, 43', 43", 54) of the same particular characteristic and that the marking on tubes of the same size are of the same characteristic whereas the marking on tubes of different sizes are of different characteristics.

12. A set of packs according to Claim 11 , characterised in that the markings (22) of tubes (1, Γ, 1") of different sizes are of different colours.

13. A set of packs according to Claim 11 , characterised in that the markings (22) of tubes (1, Γ, 1") of different colours are of different patterns.

14. A method of making a tracheostomy tube pack including the steps of forming a tracheostomy tube (1 , Γ, 1") having a non-alphanumeric visible marking (22) of a particular characteristic on a part (20) of the tube visible externally of the patient when the tube is inserted in a patient, forming an inner cannula (30, 30', 30") dimensioned to fit within the tracheostomy tube and having a marking of the same characteristic as the tracheostomy tube, providing packaging (40, 40' 40") also having a marking (43, 43', 43") of the same characteristic as the tracheostomy tube (1, , 1") and inner cannula (30, 30', 30") and placing the tracheostomy tube and inner cannula in the packaging (40, 40' 40") to complete the pack so that the nature of the tube and inner cannula in the pack can be determined from the marking on the pack.
